JP5000745B2 - Content distribution system and content distribution method - Google Patents

Description

  The present invention relates to a content distribution system and a content distribution method for distributing and presenting, for example, content for advertisement or promotion to a fixed terminal having a content presentation medium using a communication network using IMS (IP Multimedia Subsystem). .

  The Open Mobile Alliance (OMA), which defines application implementation standards in the field of mobile communications, defines an architecture and delivery method for dynamic content delivery called Dynamic Content Delivery (DCD). The DCD standard stipulates specifications for automatically distributing standby screens to terminals. According to the DCD specification, a telecommunications carrier places a DCD server that controls content distribution in its network, and prescribes Pull-type and Push-type distribution functions for terminals that have a DCD client installed in advance. In addition, the DCD client can register profile information related to content distribution, such as a content distribution channel, with the DCD server, and in response to this, the DCD server cooperates with the profile server and location information server in the IMS network. It is prescribed. In the DCD architecture, it is assumed that the content to be distributed is registered in advance in the DCD server, and the service provider registers the content in the DCD server in advance.

  In addition, as a content distribution method in DCD, methods such as SIP Push, SMS, HTTP, and WAP Push are assumed. DCD only stipulates that one of these is used as a delivery method, and there is no provision regarding the decision logic of the delivery method. Therefore, it is assumed that a provider that provides a DCD service prepares a DCD server and a DCD client that support any protocol (see, for example, Non-Patent Document 1).

  On the other hand, the Next Generation Network (NGN) discussed in ITU-T and the like assumes a network architecture in which services are provided via an IP (Internet Protocol) network. NGN has decided to adopt the IP Multimedia Subsystem (IMS) established by 3GPP, the standardization organization for third-generation mobile communication networks, and provides network services using this IMS. . IMS is a subsystem that performs service execution control, session control between terminals, registration processing, charging processing, and the like by using SIP (Session Initiation Protocol) (see, for example, Non-Patent Document 2).

  In the IMS, various applications are executed using a SIP application server (SIP AS). By using the SIP application server, IMS can not only establish a multimedia session between two parties but also realize an extended service. For example, NGN defines an interface with an application called ANI (Application Network Interface). The ANI is an interface that provides a communication path for realizing information exchange and the like between an application and an NGN function. On the other hand, in NGN, by using a SIP application server, an application can be disclosed to other networks in the form of API.

  In addition, as specifications relating to management of terminal location information in IMS, OMA also defines LOCSIP, which is an enabler that transmits location information based on SIP. LOCSIP is an XML-based location information notification technology that uses SIP SUBSCRIBE and NOTIFY methods, and it is assumed that not only terminals but also SIP-compatible entities in the NW receive notification of location information (for example, non- (See Patent Document 3).

  Further, OMA defines an XDM (XML Document Management) enabler specification as a specification of a function for managing user profiles. The XDM enabler provides a function for accessing and updating information related to a user-specific service stored in a network, which is defined and managed in an XML document (for example, Non-Patent Document 4). reference.).

  By the way, in recent years, services such as digital signage have been provided for advertising and promotion by displaying digital content on a fixed display installed on the street. These advertising services predict a passerby in front of the display in advance according to a time zone, a place, etc., and repeatedly display fixed content.

OMA; Dynamic Content Delivery v1.0. Open Mobile Alliance, Dec. 2009. Internet <URL: http://www.openmobilealliance.org/ Technical / elease_program / dcd_v1-0.aspx> 3GPP IP Multimedia (IM) Subsystem; IP Multimedia Subsystem (IMS); Stage 2 (Release 8), 3rd Generation Partnership Project (3GPP), Mar. 2009.

Open Mobile Alliance, Sep. 2008. Internet <URL: http: //www.openmobilealliance.org/Technical/release_program/xdm_v2_0.aspx>

  However, with this type of conventional advertising service, content is distributed based on pre-observed statistics, so it is not possible to display content suitable for individual users who actually pass through the display, It does not necessarily show the maximum advertising effect for passers-by.

  In addition, providing services with higher added value to users by linking functions of a fixed communication network and a mobile communication network, as typified by FMC, has been studied. Since the mobile communication network and the fixed communication network are generally constructed independently, the terminal profile information is individually managed by each communication network. Since the conventional technology basically assumes that the profile information and position information of the terminal are used in a single communication network, it is not possible to use profile information and position information collected in other communication networks. Can not. For example, the DCD enabler assumes cooperation with profile information and position information, but an interface for handling profile information of other communication networks is not defined. For this reason, even if the fixed communication network tries to realize an advertising service that conforms to the profile information of the mobile terminal by linking the functions of the fixed communication network and the mobile communication network, the mobile terminal managed by the mobile communication network The profile information of the fixed communication network could not be used.

  The present invention has been made paying attention to the above circumstances, and the purpose of the present invention is to allow the functions of existing mobile communication networks and fixed communication networks to cooperate with each other to present content suitable for individual users, Accordingly, it is an object of the present invention to provide a content distribution system and a content distribution method that can exhibit higher advertising effects.

In order to achieve the above object, one aspect of the present invention is to provide a mobile communication network using IMS (IP Multimedia Subsystem) in which a plurality of mobile terminals are accommodated, and a content presentation function distributed in a plurality of regions A fixed communication network using IMS in which a plurality of fixed terminals are accommodated, and a distribution control server connected to each of the mobile and fixed communication networks.
Then, means for managing the position information of the plurality of mobile terminals and the profile information of the users on the mobile communication network using the storage medium, and the position information and profile information of the mobile terminal that is the content presentation target from the storage medium. Selective transmission means for selectively reading and transmitting is provided. The distribution control server includes mobile terminal information acquisition means for acquiring location information and profile information of the mobile terminal that is the content presentation target from the mobile communication network, and location information of the acquired mobile terminal that is the content presentation target Means for transmitting a content distribution request including the information to the fixed communication network. Further, the fixed communication network includes means for managing position information of the plurality of fixed terminals using a storage medium, and a position of a mobile terminal that is a content presentation target included in the content distribution request when the content distribution request is received. Content selection means for selecting a fixed terminal located in an area including the location of the mobile terminal to be presented based on the information and the position information of the fixed terminal managed by the storage medium, and the selection Means for establishing a session between the fixed terminal and the requesting distribution control server. Furthermore, the distribution control server selects content corresponding to the profile based on the acquired profile information of the mobile terminal that is the content presentation target, and the selected content is transmitted to the fixed communication network. And a means for delivering to the selected fixed terminal via the session established by.

  Therefore, the distribution control server is interposed between the mobile communication network and the fixed communication network, so that the fixed communication network uses the location information of the mobile terminal managed by the mobile communication network to fix the content distribution target. It is possible to specify a terminal and distribute and present content corresponding to the profile information of the mobile terminal to the fixed terminal. For this reason, it becomes possible to present information of interest to the user at the location where the mobile terminal user exists, and a high advertising effect can be expected. Moreover, since the present invention is realized by utilizing the management function of the location information and profile information of the terminals provided in the mobile communication network and the fixed communication network, all functions are newly added to the distribution control server. There is an advantage that it can be realized easily and inexpensively as compared with the case where it is provided.

One aspect of the present invention is characterized by comprising the following aspects.
A first mode is a mobile terminal that is a content distribution target transmitted from the content distribution provider server when a content distribution provider server having a function of storing and distributing content is connected to the distribution control server. The distribution control server receives information designating the mobile terminal, and transmits a mobile terminal search request including the designation information to the mobile communication network. On the other hand, the mobile communication network reads the location information and profile information of the mobile terminal corresponding to the designation information included in the mobile terminal search request transmitted from the distribution control server from the storage medium, and this read location information And profile information is returned to the distribution control server.

  In this way, when the content distribution provider server designates the mobile terminal user, the location information and profile information of the mobile terminal user are retrieved by the mobile communication network and notified to the distribution control server. Then, the fixed terminal is selected by the fixed communication network using the notified position information, and the content is selected and distributed by the distribution control server using the notified profile information. For this reason, it becomes possible to present the content in which the mobile terminal user is interested in a location where the mobile terminal user exists, targeting a specific mobile terminal user.

  In the second aspect, when a content distribution provider server having a function of storing and distributing content is connected to the distribution control server, designation of at least a content distribution target area transmitted from the content distribution provider server The distribution control server receives distribution conditions including information, and transmits a registration request for the distribution conditions to the mobile communication network. On the other hand, when the mobile communication network receives the registration request for the distribution condition transmitted from the distribution control server, the mobile communication network stores the distribution condition included in the received registration request, and the content included in the stored distribution condition. The position information and profile information of the mobile terminal existing in the distribution target area are detected from the storage medium and returned to the distribution control server.

  In this way, when the content distribution company server designates a region as a distribution condition, a mobile terminal existing in this region is searched by the mobile communication network, and its location information and profile information are notified to the distribution control server. . Then, the fixed terminal is selected by the fixed communication network using the notified position information, and the content is selected and distributed by the distribution control server using the notified profile information. For this reason, it becomes possible to distribute and present content that the user is interested in to a mobile terminal user existing in this area, targeting a specific area.

  According to a third aspect, when a fixed communication network manages profile information representing a data format of content handled by a plurality of fixed terminals using a storage medium, the distribution control server serves as a fixed terminal to which the content is distributed. Profile information is acquired from the fixed communication network, and the data format of the content is converted into a format that can be handled by the fixed terminal of the distribution destination based on the acquired profile information of the fixed terminal.

  In this way, the data format of the content is converted in the distribution control server in accordance with the content decoding method, display specifications, etc. provided in the fixed terminal. For this reason, even when the data format handled by the fixed terminal is different for each fixed terminal, the content can be displayed in an appropriate format according to the data format of the fixed terminal.

  According to a fourth aspect, in a state where content corresponding to profile information of a mobile terminal that is a content presentation target is presented on a fixed terminal, operation information transmitted from the mobile terminal that is the content presentation target is transmitted by the distribution control server. In response to the received operation information, the distribution control server reselects content related to the content being presented, and the reselected content is fixed to the distribution control server by a fixed communication network. This is distributed to a fixed terminal through a session established with the terminal.

  In this way, when the mobile terminal user who has viewed the content presented on the fixed terminal operates his / her mobile terminal, the content of the content being presented can be changed according to the operation content. For example, it is possible to present a sequel or a continuation page or detailed contents of the content being presented, or to present other content related to the content being presented.

  In the fifth aspect, the distribution control server receives the operation information for requesting switching of the distribution destination of the content transmitted from the mobile terminal in a state where the content is presented on the fixed terminal. When the received operation information is information requesting to switch the content distribution destination from the fixed terminal to the mobile terminal, the distribution control server includes the mobile terminal included in the operation information. Based on the identification information, the fixed communication network is made to release the corresponding session established with the fixed terminal, and the new session is established with the mobile terminal. To the mobile communication network. The same content as the content presented on the fixed terminal based on the identification information of the content being presented and the information indicating the presentation status at the time of the switching operation of the content included in the operation information And the selected content is distributed from the presentation position at the time of the switching operation to the mobile terminal via the newly established session.

  In this way, when the user performs a switching operation of the distribution destination in the mobile terminal in order to switch the distribution destination of the content to the mobile terminal in a state where the content is distributed and displayed on the fixed terminal, the distribution destination of the content being distributed Switches from a fixed terminal to a mobile terminal. For this reason, for example, even when the user leaves the installation location of the fixed terminal, it is possible to continue browsing the same content on his / her mobile terminal.

  In the sixth aspect, the distribution control server receives operation information for requesting switching of the distribution destination of the content transmitted from the mobile terminal in a state where the content is presented at the mobile terminal. When the received operation information is information requesting to switch the content distribution destination from the mobile terminal to the fixed terminal, the distribution control server also includes the identification information of the mobile terminal included in the operation information. In addition, the location information of the mobile terminal is acquired from the mobile communication network, and based on the acquired location information of the mobile terminal and the location information of the fixed terminal managed by the storage medium, A terminal is selected, and a new session is established between the selected fixed terminal and the requesting distribution control server. The distribution control server then presents the content presented to the mobile terminal based on the identification information of the content being presented and information indicating the presentation status at the time of the switching operation of the content, which is included in the operation information. The same content is selected, and the selected content is distributed from the presentation position at the time of the switching operation to the fixed terminal via the newly established session.

  In this manner, when the user performs a distribution destination switching operation on the mobile terminal in order to switch the content distribution destination to the fixed terminal in a state where the content is distributed and displayed on the mobile terminal, the distribution destination of the content being distributed is changed. Switch from a mobile terminal to a fixed terminal. For this reason, for example, when the user approaches the installation location of the fixed terminal while browsing the content on his / her mobile terminal and desires to browse on the fixed terminal, the same content can be continuously browsed on the fixed terminal. Become.

According to the seventh aspect, when the distribution control server receives the operation information for requesting the reproduction control of the content transmitted from the mobile terminal in a state in which the content is presented on the fixed terminal, the seventh mode responds to the received operation information. Based on the identification information of the mobile terminal included in the operation information, the corresponding session established with the fixed terminal is searched, and the fixed communication network is updated. Then, based on the reproduction control information of the content being presented included in the operation information, the reproduction state of the content on the fixed terminal is controlled.
Examples of the type of content playback state control include fast-forwarding, pausing, rewinding, or changing the playback location of the content.

  In this way, when the user performs an operation for controlling the reproduction state of the content while the content is being distributed and displayed on the fixed terminal, the reproduction state of the content being distributed to the fixed terminal is controlled. Accordingly, by operating the user's mobile terminal, the user can remotely fast forward, pause, rewind, or change the playback location of the content being presented on the fixed terminal.

In an eighth aspect, the mobile terminal is provided with a plurality of position measuring means having different signal transmission sources for position measurement, the position information selectively measured by the plurality of position measuring means, and the plurality of position measurements. Any one of the position information obtained by combining the plurality of position information measured by the means is transmitted to the mobile communication network and stored in the position information server.
In this way, as position measurement means, positions transmitted from a plurality of sources such as wireless LAN access points, GPS satellites, femtocell base stations, contactless IC cards as well as mobile communication network base stations Position information can be acquired based on each measurement signal. For this reason, when the user is in the vicinity of the fixed terminal, the position information can be acquired with high accuracy.

In the ninth aspect, the mobile terminal is provided with a plurality of operation input means having different input forms, and generates operation information including a request corresponding to the input information according to information input by the operation input means, The generated operation information is transmitted to the distribution control server.
If it does in this way, a user will be able to perform operation intuitively by cooperation with various sensors, such as an acceleration sensor and a gyro sensor, for example, and it will become possible to collect user context.

  A tenth aspect includes a mobile communication network using an IMS (IP Multimedia Subsystem) that includes means for storing a plurality of mobile terminals and storing location information of the mobile terminals and profile information of the users, respectively. And a fixed communication network using IMS having means for storing a plurality of fixed terminals distributed in the area and storing arrangement position information of these fixed terminals, and a plurality of functions having a function of storing and distributing contents An API (Application) is arranged between the content distribution provider server, each of the mobile and fixed communication networks and the plurality of content distribution provider servers, and between each of the plurality of content distribution provider servers. A distribution control server capable of selectively performing communication using a programming interface) function, wherein the distribution control server includes: The mobile terminal receives location information and user profile information of the mobile terminal from the mobile communication network, and based on the received location information of the mobile terminal and the location information of the fixed terminal stored in the fixed communication network A fixed terminal arranged in an area including the location of the mobile terminal to be presented is selected, and information for associating the selected fixed terminal with the mobile terminal is stored. Then, the content corresponding to the user profile information of the mobile terminal is selected, and the access destination information for accessing the content server storing the selected content is notified to the fixed terminal associated with the mobile terminal. The access request transmitted from the fixed terminal that is the notification destination is transferred to the content distribution provider server, so that the content distribution provider server performs the content distribution processing.

  Therefore, by providing the API function on the distribution control server, it becomes possible for the distribution control server to communicate with each of the plurality of content distribution provider servers. Content can be distributed to any fixed terminal among a plurality of fixed terminals of the communication network. That is, each content distribution company does not need to install and operate a dedicated fixed terminal, and can share a large number of public fixed terminals connected to the fixed communication network.

  In addition, the mobile terminal and the fixed terminal arranged in the vicinity thereof are associated across the communication network. For this reason, various display processes of content can be performed in cooperation between the mobile terminal and the fixed terminal. For example, it is possible to display the same or related content on the mobile terminal and the nearby fixed terminal, or change the content displayed on the fixed terminal in accordance with a user operation on the mobile terminal. In addition, since the content selection process based on the user profile information is performed on the distribution control server, there is no concern that the user profile information will be known to the content distributor, thereby maintaining high confidentiality of the user's personal information. can do.

  In addition, when a content server operated by a content holder is provided independently of the content distributor server, an API function may be provided on each of the content distributor servers. In this way, each content distribution company server can take out and distribute the content from any of the plurality of content servers. That is, it is possible to separate each content server (content holder) and each content distribution provider server (distribution provider).

  According to an eleventh aspect, the distribution control server includes a content filter, and based on the user profile information of the mobile terminal and the profile information of the fixed terminal associated with the mobile terminal, the content filter changes the content server to the fixed terminal. The distribution policy information indicating whether or not the content can be distributed is set. Then, when an access request is sent from the fixed terminal that has notified the access destination information, transfer of the access request to the content distribution server is restricted based on the distribution policy information.

  In this way, content that should not be displayed on a specific fixed terminal can be prevented from being distributed according to the relationship between the user profile information of the mobile terminal and the profile information of the fixed terminal of the distribution destination. Thus, for example, content including personal information of the user or information related thereto can be prevented from being displayed on a public fixed terminal that displays information to an unspecified number of people such as an electronic bulletin board. In addition, since the restriction process is performed in response to the access request, it is possible to more appropriately restrict the distribution of inappropriate content compared to the case where the restriction process is performed on the distributed content.

In the twelfth aspect, the distribution control server monitors the change in the location information of the mobile terminal, and whether the location information of the mobile terminal has gone out of the area where the fixed terminal associated with the mobile terminal is located. Determine. When it is determined that the location information of the mobile terminal has gone out of the area where the fixed terminal is located, the information associating the mobile terminal with the fixed terminal and the distribution policy information are deleted. is there.
In this way, when the user of the mobile terminal moves away from the arrangement position of the fixed terminal, the information that associates the mobile terminal with the fixed terminal and the distribution policy information are automatically deleted. For this reason, when leaving the front of the fixed terminal, there is no need for the mobile terminal user to perform an operation to end the display of the content displayed on the fixed terminal.

  That is, according to the present invention, contents suitable for individual users can be presented by linking the functions of an existing mobile communication network and a fixed communication network, thereby further enhancing the information presentation effect. A distribution system and a content distribution method can be provided.

Then, the retrieved list of fixed terminals is returned to the SIP application server 25.

Next, an embodiment of the content distribution operation by the system configured as described above will be described.
Example 1
In the first embodiment, the content distribution provider server designates a specific mobile terminal that is a content presentation target, and acquires position information and profile information of the designated mobile terminal from the mobile IMS network. Then, a fixed terminal arranged at a position close to the acquired position information is selected by the fixed IMS network, a session is established between the fixed terminal and the content distributor server, and the profile information of the mobile terminal is set. The corresponding content is distributed to a fixed terminal and displayed.

5 and 6 are sequence diagrams showing the operation procedure.
In the mobile IMS network NW1, each of the mobile terminals MS1 to MSn transmits its location information to the S-CSCF 11 via the P-CSCF 12 each time the power is turned on or moves between cells. When receiving the location information of the mobile terminals MS1 to MSn, the S-CSCF 11 sends this location information to the location information server 17. When receiving the position information, the position information server 17 newly registers the position information in the position information database or updates the corresponding information in the position information database. When the position registration process is completed, a position information registration completion notification is returned. This location information registration completion notification is transferred from the S-CSCF 11 to the source mobile terminals MS1 to MSn via the P-CSCF 12. Thereafter, the location information in the location information database is updated each time the location of the mobile terminals MS1 to MSn changes.

  In this state, it is assumed that a specific mobile terminal user (for example, MSi) to be a content presentation target is specified in the content distribution provider servers AP1 and AP2, and a content distribution request including this specification information is transmitted. When the distribution control server DSV receives the content distribution request, the distribution control server DSV transmits a confirmation request for the condition-compliant terminal position information to the SIP application server 15 of the mobile IMS network NW1. Upon receipt of this confirmation request, the SIP application server 15 transmits a condition-compatible terminal search request to the location information server 17. When receiving the search request, the location information server 17 searches the location information database based on the designation information of the mobile terminal included in the received search request, and reads the location information of the corresponding mobile terminal MSi. If a plurality of mobile terminal users are designated as specific mobile terminal users, the location information of these mobile terminals is listed. Then, the created list of location information of the mobile terminal is returned to the SIP application server 15.

  Subsequently, the SIP application server 15 sends an acquisition request (distribution policy request) for the profile information of the mobile terminal MSi to the user profile database 16 and receives the profile information of the corresponding mobile terminal MSi from the database 16 as a distribution policy response. To do. Then, the acquired location information and profile information of the corresponding terminal MSi are returned to the distribution control server DSV as a response notification of the condition-compliant terminal location information.

  When receiving the response notification of the condition-compliant terminal location information, the distribution control server DSV next transmits a content distribution request to the SIP application server 25 of the fixed IMS network NW2, as shown in FIG. When this content distribution request is received, the content push distribution procedure X is executed as follows in the fixed IMS network NW2.

  That is, when receiving the content distribution request, the SIP application server 25 transmits a search request for a fixed terminal as a distribution destination to the position information server 27. When receiving the search request, the location information server 27 is based on the location information of the mobile terminal MSi included in the search request, and is a fixed terminal installed within a predetermined range centering on the location of the mobile terminal MSi. Search for. For example, the fixed terminal FSj installed within a radius of 50 m around the position of the mobile terminal MSi is searched. At this time, when a plurality of fixed terminals matching the conditions are searched, these are listed. Then, response information representing the search result is returned to the SIP application server 15.

  Subsequently, the SIP application server 15 sends a profile acquisition request of the fixed terminal FSj to the user profile database 26 based on the information of the fixed terminal FSj described in the response information representing the search result, and from the database 26 The profile information of the corresponding fixed terminal FSj is received.

  Next, the SIP application server 15 sends to the S-CSCF 21 a session establishment request for establishing a session between the own server 15 and the searched fixed terminal FSj. Upon receiving the session establishment request, the S-CSCF 21 transmits / receives a session establishment request and its establishment response to / from the fixed terminal FSj, and returns this establishment response to the SIP application server 15. Thus, a session is established between the SIP application server 15 and the fixed terminal FSj.

  Furthermore, the SIP application server 15 sends a session establishment request for establishing a session between the server 15 and the distribution control server DSV to the S-CSCF 21. Upon receiving the session establishment request, the S-CSCF 21 transmits / receives a session establishment request and its establishment response to / from the distribution control server DSV, and returns this establishment response to the SIP application server 15. Thus, a session is established between the SIP application server 15 and the distribution control server DSV, and the distribution control server DSV and the fixed terminal FSj are established by this session and the session previously established with the fixed terminal FSj. During this period, a session for content distribution is established.

  When the session is established, a session establishment completion notification is sent from the SIP application server 15 to the S-CSCF 21 and further transferred to the fixed terminal FSj. When the fixed terminal FSj receives the session establishment completion notification, the fixed terminal FSj transmits a content distribution request to the distribution control server DSV. Upon receiving this content distribution request, the distribution control server DSV, based on the profile information of the mobile terminal MSi previously obtained from the SIP application server 15 of the mobile IMS network NW1, identifies content information corresponding to the profile information. Select. For example, the identification information of the corresponding content is selected from the list of distribution content classified in advance according to the age, sex, occupation, hobby, etc. of the user described in the profile information and stored in the memory. And the content delivery request | requirement containing the identification information of this selected content is transmitted to content delivery provider server AP1, AP2.

  When the content distribution request is received, the content distribution provider servers AP1 and AP2 read the corresponding content from the content database 35 and transmit it according to the content identification information included in the received content distribution request. As a result, the content is transferred to the fixed terminal FSj via the distribution control server DSV.

  Note that in the content transfer process, the distribution control server DSV uses the fixed terminal FSj profile information acquired from the SIP application server 25 of the fixed IMS network NW2 as the content data format. Conversion is performed so that the format can be handled by FSj. For this reason, the content is appropriately displayed on the fixed terminal FSj regardless of the data format or display specifications of the fixed terminal FSj.

  Finally, when the content transfer ends, a session end notification is sent from the distribution control server DDSV to the fixed terminal FSj via the SIP application server 25. Then, a session end confirmation is returned from the fixed terminal in response to this session end notification, and when this end confirmation is transferred to the distribution control server DSDV via the SIP application server 25, the content distribution operation of the system ends.

(Example 2)
In the second embodiment, the content distribution provider server specifies content distribution conditions, and acquires location information and profile information of the mobile terminal that meets the specified distribution conditions from the mobile IMS network. Then, a fixed terminal arranged at a position close to the acquired position information is selected by the fixed IMS network, a session is established between the fixed terminal and the content distributor server, and the profile information of the mobile terminal is set. The corresponding content is distributed to a fixed terminal and displayed.

FIG. 7 is a sequence diagram showing the operation procedure. Since the location information management procedure of the mobile terminals MS1 to MSn in the mobile IMS network NW1 has been described in the first embodiment (FIG. 5), description thereof is omitted here.
In the content distribution provider servers AP1 and AP2, the operator inputs content distribution conditions. The distribution condition is input by displaying a distribution condition input screen as shown in FIG. 8 on the operation terminal and inputting the condition on this input screen or selecting from a list prepared in advance. . The distribution condition to be input includes position information of a content distribution target area, profile information of a mobile terminal user serving as a distribution target, and a URL indicating a location where the content to be distributed is stored. When the operator finishes inputting the distribution conditions and performs a transmission operation, a distribution condition registration request is transmitted from the content distribution provider servers AP1 and AP2 to the distribution control server DSV.

  When the distribution control server DSV receives the distribution condition registration request, the distribution control server DSV transfers the registration request to the SIP application server 15 of the mobile IMS network NW1. Upon receiving this distribution condition registration request, the SIP application server 15 sends the distribution condition to the location information server 17. The location information server 17 stores the delivery condition in the memory, and returns a delivery condition registration completion notification to the SIP application server 15 after the storage process is completed. The distribution condition registration completion notification is returned from the SIP application server 15 to the distribution control server DSV, and further transferred to the requesting content distribution provider servers AP1 and AP2.

  Now, it is assumed that the mobile terminal MSi in this state moves to the area designated as the distribution condition or is turned on in this area. Then, the location information of the mobile terminal MSi stored in the location information database of the location information server 17 is updated to the new one. The location information server 17 determines whether or not the updated location information of the mobile terminal MSi meets the delivery conditions stored in the memory. For example, it is determined whether or not the location of the mobile terminal MSi is included in the area represented by the location information described in the distribution conditions. As a result of this determination, if the location information of the mobile terminal MSi matches, the identification information of the mobile terminal MSi is transmitted to the SIP application server 15.

  Subsequently, when the SIP application server 15 receives the identification information of the mobile terminal MSi that meets the above distribution conditions, the SIP application server 15 accesses the user profile database 16 based on the received identification information, and profile information of the mobile terminal MSi. To get. When the profile information is acquired, the SIP application server 15 compares the acquired profile information of the mobile terminal MSi with the profile information described in the distribution conditions of the distribution condition memory, and determines whether or not distribution is possible. For example, if the profile information described in the distribution conditions is “male in his twenties” as shown in FIG. 8 and the profile information of the mobile terminal MSi is also “male in his twenties”, the two match. Therefore, it is determined that delivery is possible. Then, a content distribution request including information indicating that the distribution is possible and position information of the distribution target area described in the distribution condition is generated, and the content distribution request is transmitted to the distribution control server DSV.

  Upon receiving the content distribution request from the SIP application server 15, the distribution control server DSV transmits the content distribution request to the SIP application server 25 of the fixed IMS network NW2. Then, in the fixed IMS network NW2, the content push distribution procedure X shown in FIG. 6 is executed in the same manner as in the first embodiment described above. As a result, the content specified by the URL according to the distribution condition is the content distribution operator. Content is distributed from the servers AP1 and AP2 to the fixed terminal FSj.

  As described above in detail, in the first embodiment, a specific mobile terminal MSi that is a content presentation target is specified from the content distribution provider servers AP1 and AP2, or a distribution condition including a content distribution location and a profile is specified. Then, the distribution control server DSV acquires the location information and profile information of the specified mobile terminal MSi or mobile terminal that meets the distribution conditions from the mobile IMS network NW1. Then, the fixed terminal FSj arranged at a position close to the acquired position information is selected by the fixed IMS network NW2, and a session is established between the fixed terminal FSj and the content distributor server AP1, AP2. The content corresponding to the profile information of the mobile terminal MSi is distributed to the fixed terminal FSj and displayed.

  Therefore, using the location information and profile information management function of the mobile terminals MS1 to MSn included in the mobile IMS network NW1 and the location information management function and session control function provided in the fixed IMS network NW2 as a distribution target. It is possible to select the fixed terminal FSj arranged near the terminal MSi, and to distribute and display the content corresponding to the profile information of the mobile terminal MSi on the fixed terminal FSj. For this reason, it becomes possible to present information of interest to the mobile terminal user at a place where the mobile terminal user exists, and a high content effect can be expected. Moreover, since the present invention is realized by using the terminal location information and profile information management functions provided in the mobile IMS network NW1 and the fixed IMS network NW2, all functions are provided to the distribution control server DSV. There is an advantage that it can be realized easily and inexpensively as compared with the case where it is provided.

  Further, a distribution method in which the content distribution provider servers AP1 and AP2 specify mobile terminals to be distributed, a region to which the content distribution provider servers AP1 and AP2 are distributed, and a user profile to be distributed as distribution conditions. The specified delivery method can be used selectively.

  Further, the distribution control server DSV acquires the profile information of the fixed terminals FS1 to FSm, which are the distribution destinations of the content, from the fixed IMS network NW2, and the content data based on the acquired profile information of the fixed terminals FS1 to FSm. The format is converted into a format that can be handled by the fixed terminals FS1 to FSm as distribution destinations. For this reason, even when the content decoding method, display specifications, etc. handled by the fixed terminals FS1 to FSm are different for each of the fixed terminals FS1 to FSm, the content can be displayed in an appropriate format according to the data format of the fixed terminals FS1 to FSm. It becomes possible.

(Second Embodiment)
In the second embodiment of the present invention, in a state where content is displayed on a fixed terminal, the operation information transmitted from the mobile terminal that is the distribution target of the content is transmitted via the mobile IMS network NW1 to the distribution control server. In response to the received operation information, the distribution control server DSV reselects the content related to the content being displayed, and distributes the reselected content to the fixed terminal. .

  FIG. 9 is a diagram showing an outline of the operation, and FIG. 10 is a block diagram showing the functional configuration of the system. The basic configurations of the mobile IMS network NW1, the fixed IMS network NW2, the distribution control server DDSV, and the content distribution provider servers AP1 and AP2 in this embodiment are the same as those in the first embodiment. 4 will be explained.

  The mobile IMS network NW1 manages the location information of each mobile terminal MS1, MS2,. In this state, when the mobile terminal MS1 enters the content distribution target area (management area E1) designated in advance by the distribution conditions, the mobile IMS network NW1 uses the SIP application server 15 to obtain the location information and profile information of the mobile terminal MS1. The content distribution request including it is transmitted to the distribution control server DSV.

The distribution control server DSV includes a content distribution request receiving unit 61, a distribution content determining unit 62, a mobile terminal link function unit 63, and a distribution content control unit 64 as control functions according to the present invention.
The content distribution request receiving unit 61 receives the content distribution request (1) transmitted from the SIP application server 15 of the mobile IMS network NW1. When the content distribution request (1) is received, the distribution content determination unit 62 instructs the mobile terminal link function unit 63 to transmit the alert message (2) to the mobile terminal MS1. In response to the transmission instruction, the mobile terminal link function unit 63 transmits the alert message (2) to the mobile terminal MS1.

  The distribution content determination unit 62 selects content corresponding to the profile of the mobile terminal user based on the profile information included in the content distribution request (1), and instructs the distribution content control unit 64 to distribute the content. To do. The distribution content control unit 64 gives a content distribution request (3) to the SIP application server 25 of the fixed IMS network NW2 in accordance with the above instruction.

  When the SIP application server 25 of the fixed IMS network NW2 receives the content distribution request, the SIP application server 25 becomes a distribution destination installed in the area where the mobile terminal MS1 exists based on the location information included in the distribution request. The fixed terminal FS1 is selected (4). At the same time, a process for establishing a session between the selected fixed terminal FS1 and the distribution control server DSV is executed. The distribution content control unit 64 of the distribution control server DSV transfers the selected content (5) to the fixed terminal FS1 through the media transfer path formed by the established session.

  Further, the mobile terminal link function unit 63 of the distribution control server DSV has a function of receiving content distribution control information (6) transmitted from the mobile terminal MS1 in response to the transmission of the alert message, that is, a content update request. The distribution content determination unit 62 updates the distribution content in response to the received update request and instructs the distribution content control unit 64.

Next, the operation of the system configured as described above will be described with reference to FIG.
When the mobile terminal MS1 enters the content distribution target area (management area E1), a content distribution request including the location information and profile information of the mobile terminal MS1 is sent from the SIP application server 15 of the mobile IMS network NW1 to the distribution control server DSV. Sent. When receiving the location information and profile information of the mobile terminal MS1, the distribution control server DSV first transmits a message for calling attention to the content display to the mobile terminal MS1 in step 6a.

  At the same time, the distribution control server DSV sends a content distribution request to the SIP application server 25 of the fixed IMS network NW2. As a result, under the control of the SIP application server 25, the fixed terminal FS1 in the management area where the mobile terminal MS1 exists is selected based on the location information of the mobile terminal MS1 included in the content distribution request. A session is established between the fixed terminal FS1 and the distribution control server DSV. Then, the distribution control server DSV selects content corresponding to the profile information of the mobile terminal MS1, and transfers and displays this content to the fixed terminal FS1 via the session.

  In this state, it is assumed that the user of the mobile terminal MS1 who has visually recognized the content displayed on the fixed terminal FS1 inputs a content update request at the mobile terminal MS1. Then, in step 6b, the update request is sent as a response to the message to the distribution control server DSV via the mobile IMS network NW1. When the distribution control server DSV receives the update request, the distribution control server DSV changes the content of the content to be distributed in accordance with the content of the update request received in step 6c, and the changed content is already transferred to the fixed terminal FS1. Transfer to the fixed terminal FS1 via the established session.

  Therefore, according to the second embodiment, the user of the mobile terminal MS1 can change the content of the content displayed on the fixed terminal FS1 in accordance with his / her operation. For example, a sequel or a continuation page of the content being presented can be presented, or another content related to the content being presented can be presented.

(Third embodiment)
In the third embodiment of the present invention, when the content distributed from the distribution control server is displayed on the mobile terminal or the fixed terminal and the content distribution destination switching operation is performed on the mobile terminal, The terminal that is the delivery destination is switched from the mobile terminal to the fixed terminal, or from the fixed terminal to the mobile terminal.

FIG. 11 is a schematic configuration diagram of a content distribution system according to the third embodiment of the present invention. In the figure, the same parts as those in FIG.
In addition to the function of performing wireless communication with the mobile IMS network NW1, the mobile terminals MS1 to MSn are connected to a wireless LAN (Local Area Network) access point, a femtocell base station, and a GPS (Global Positioning System) satellite. It also has a function to communicate between them. Then, the position (latitude and longitude) of the terminal is calculated based on signals transmitted from these access points, femtocell base stations, and GPS satellites. That is, it has a function of measuring the position of its own terminal using a plurality of position measurement media. For this reason, it is possible to perform position measurement with higher accuracy than before. The measured position information is uploaded to the position information server 17 of the mobile IMS network NW1 and managed.

  The mobile terminals MS1 to MSn are provided with various sensors such as an acceleration sensor and a gyro sensor. Based on the detection data of these sensors, it is possible to generate a wider variety of user context information and more intuitive terminal operations.

By the way, the distribution control server DSV further includes the following functions as its control functions.
That is, in a state where the content transmitted from the content distribution server AP1 or AP2 is distributed and displayed to the mobile terminals MS1 to MSn or the fixed terminals FS1 to FSM, the content distribution destinations from the mobile terminals MS1 to MSn are displayed. When the switching request is received, the session is reestablished based on the location information of the mobile terminal managed by the mobile IMS network NW1 and the fixed IMS network NW2, the address information of the fixed terminal, etc. The process of switching the distribution destination of the content being distributed from the mobile terminals MS1 to MSn to the fixed terminals FS1 to FSM or vice versa.

Next, the content display switching operation in the system configured as described above will be described using two embodiments.
Example 1
In the first embodiment, when the content is distributed and displayed on the mobile terminal MS1, the user performs a distribution destination switching operation on the mobile terminal MS1 to switch the content distribution destination to the fixed terminal FS1. The DSV switches the distribution destination of the content being distributed from the mobile terminal MS1 to the fixed terminal FS1.

FIG. 12 is a diagram for explaining an outline of the switching operation, FIG. 14 is a diagram showing an outline of a control sequence between the respective parts in the system, and FIGS. 15 and 16 are diagrams showing details of the control sequence.
It is assumed that the user performs a content distribution destination switching operation on the mobile terminal MS1 while the content is being displayed on the mobile terminal MS1. For example, a specific button operation of the mobile terminal MS1 or an operation of shaking the mobile terminal MS1 is used for the distribution destination switching operation. When the delivery destination switching operation is performed, a content delivery destination switching request is transmitted from the mobile terminal MS1 to the delivery control server DSV as shown in (1) of FIG. At this time, the switching request includes the content ID being distributed, information indicating the content reproduction position at the time of the switching operation, and the mobile terminal ID.

  When the distribution control server DSV receives the content distribution destination switching request, first, based on the mobile terminal ID included in the received switching request, the location information of the mobile terminal MS1 as shown in (2) of FIG. To the location information server 17, and the location information of the mobile terminal MS1 is acquired from the location information server 17. Subsequently, the distribution control server DSV, based on the acquired location information of the mobile terminal MS1, specifies the fixed IMS network NW2 in order to identify the fixed terminal FS1 to be distributed as shown in (3) of FIG. The location information server 27 is inquired to obtain a fixed terminal ID as a delivery destination. Next, the distribution control server DSV establishes a session with the fixed terminal FS1, as shown in (4) of FIG. 12, based on the acquired fixed terminal ID. Then, the content represented by the content ID being distributed included in the switching request is transmitted from the position indicated by the content reproduction position information included in the switching request via the media path MR formed by the session. As shown in 12 (5), it is distributed to the fixed terminal FS1. At this time, the content is converted from the data format for the mobile terminal to the data format for the fixed terminal.

(Example 2)
Example 2 is a distribution control server when the user performs a distribution destination switching operation in the mobile terminal MS1 to switch the content distribution destination to the mobile terminal MS1 while the content is distributed and displayed on the fixed terminal FS1. The DSV switches the distribution destination of the content being distributed from the fixed terminal FS1 to the mobile terminal MS1.

FIG. 13 is a diagram for explaining the outline of the switching operation.
It is assumed that the user performs a content distribution destination switching operation on the mobile terminal MS1. When this distribution destination switching operation is performed, a content distribution destination switching request is transmitted from the mobile terminal MS1 to the distribution control server DSV as shown in (1) of FIG.

The processing function of the screening unit 731 described above is included in the media distribution control unit 54 in the functional block diagram shown in FIG.

  FIG. 20 shows a configuration of a system for transmitting content and terminal operation information between the mobile terminals MS1 to MSn among the functions provided in the distribution control server DSV and the mobile SIP application server (SIP AS) 15. FIG. The transmission system between the fixed terminals FS1 to FSm has already been described with reference to FIG.

The distribution control server DSV includes a content distribution order management unit 56, a content distribution request transmission unit 57, a content distribution request response reception unit 58, a session control function unit 59, a mobile terminal content distribution unit 60, and terminal operation information reception. The unit 61 is provided.
Among these, the content distribution request transmission unit 57 and the content distribution request response reception unit transmit and receive content distribution requests and responses to and from the mobile SIP application server 15. The session control function unit 59 instructs the mobile SIP application server 15 to establish and release a session.

The mobile terminal content distribution unit 60 transfers the content data transmitted from the content servers C1 and C2 to the mobile terminals MS1 to MSn.
The terminal operation information receiving unit 61 is used by the user in the mobile terminals MS1 to MSn for operations such as a request to change the content being displayed, a request to switch the content distribution destination, and a request to update the content displayed on the fixed terminal. Is received, the terminal operation information is received and notified to the content distribution order management unit 56.
Upon receiving the terminal operation information, the content distribution order management unit 56 adds new information to the mobile content distribution request transmission unit 57 and the fixed content distribution request transmission unit 51 (shown in FIG. 2) according to the operation details. A request to distribute the correct content.

The mobile SIP application server 15 includes a content distribution request receiving unit 160, a content distribution request response transmitting unit 161, a session establishment function unit 162, and a content distribution session establishment processing unit 163.
Among these, the content distribution request reception unit 160 and the content distribution request response transmission unit 161 receive and respond to the content distribution request between the content distribution request transmission unit 57 and the content distribution request response reception unit of the distribution control server DSV. Send. The session establishment function unit 162 performs session establishment / release processing in the mobile IMS in accordance with an instruction from the session control function unit 59 of the distribution control server DSV. The content distribution session establishment processing unit 163 performs session establishment or release processing with the mobile terminals MS1 to MSn.

Next, a content distribution operation by the system configured as described above will be described. FIG. 21 shows the operation.
The user is moving with the mobile terminals MS1 to MSn, and the positions of the mobile terminals MS1 to MSn are detected using the GPS position measurement function of the terminal and the cell ID of the femtocell. The terminal location information is transmitted to and stored in the location information server 17 as indicated by (1) in FIG. The SIP AS 15 of the mobile IMSNW 1 changes the location information of the content distribution target user's mobile terminal (for example, MS 1) stored in the location information server 17 together with the terminal ID together with the terminal ID as shown in FIG. As shown in (2), it is transmitted to the distribution control server DSV.

  In the distribution control server DSV, when the location information of the mobile terminal MS1 and the terminal ID thereof are received, the ID linkage unit 71 displays the received location information of the mobile terminal MS1 from the location information server 27 of the fixed system IMSNW2. 21 is collated with the arrangement position information of the fixed terminals FS1 to FSm obtained as (3) in FIG. Then, a fixed terminal (for example, FS1) arranged within a distance set in advance with respect to the current position of the mobile terminal MS1 is selected, and the terminal ID of the selected fixed terminal FS1 and the terminal of the mobile terminal MS1 are selected. Information associated with the ID is generated. Then, the generated terminal ID association information is notified to the content filter unit 73 as indicated by (4) in FIG.

  The content filter unit 73 acquires the mobile terminal user's profile information from the user profile DB 16 of the mobile IMSNW1 based on the notified terminal ID of the mobile terminal MS1. The user profile information includes the user's age, occupation, sex, address, and the like. At the same time, information about the installation location of the fixed terminal FS1 is acquired from the user profile DB 26 of the fixed IMSNW2. For information on the installation location of the fixed terminal FS1, the fixed terminal FS1 is, for example, a shared type terminal that is installed outdoors and simultaneously presents advertisements to an unspecified number of users, or is installed indoors and has one person at a time. Information indicating whether the terminal is a personal type terminal that presents information to the user.

  The content filter unit 73 sets a content distribution policy for the fixed terminal FS1 based on the acquired user profile information and information regarding the installation location of the fixed terminal FS1. Then, the information indicating the set content distribution policy is stored in the distribution policy storage unit 72 as shown in (5) of FIG.

  For example, the fixed terminal FS1 is now a shared type terminal and the fixed terminal FS2 is a personal type terminal, and the content server CS1 stores content including personal information of the user or related information, while the content server CS2 is personal information. 22 is set for the user U1 of the mobile terminal MS1, assuming that content composed of shared information not including such information is stored.

  The content distribution policy may be set in units of content genres or individual content units, in addition to being set in units of content servers CS1 and CS2. When setting in units of content servers CS1 and CS2, it is identified by address information of the server, and when setting in units of content, it can be identified by using a content URL.

  Next, the content filter unit 73 uses the rating unit 732 to select content to be distributed to the corresponding fixed terminal FS1 based on the acquired profile information of the user of the mobile terminal MS1 and the set distribution policy. . Then, the URL for accessing the content is transmitted to the fixed terminal FS1 as indicated by (6) in FIG. 21 by using the push distribution function using SIP by the fixed IMSNW2.

  When the fixed terminal FS1 receives the content URL when the terminal is in a state where the content can be displayed, the fixed terminal FS1 transmits an access request for the content according to the received URL. This access request is transferred to the content filter unit 73 of the distribution control server DSV as indicated by (6) ′ in FIG. When receiving the access request, the content filter unit 73 determines whether or not the access request destination is a restriction target by the screening unit 731 with reference to the content distribution policy stored in the distribution destination policy storage unit 72. As a result of this determination, if the access destination is not a restriction target, the access request is relayed and transferred as it is.

  For example, if the access destination of the access request transmitted from the fixed terminal FS1 is the content server CS2, the access request is relayed and transferred as it is to the content provider server (for example, AP2) according to the content distribution policy shown in FIG. As a result, under the control of the content distributor server AP2, the content data of the content server CS2 is transferred to the fixed terminal via the media route MR set on the fixed IMSNW2 as shown in (7) of FIG. It is transferred to FS1 and displayed.

  Therefore, the user U1 of the mobile terminal MS1 can view content such as advertisements delivered to the user himself / herself at the fixed terminal FS1 installed on the street, for example. Further, when the user U1 operates his / her mobile terminal MS1 in this state, the terminal operation information is sent to the distribution control server DSV as shown in FIG. When the distribution control server DSV receives the terminal operation information, the distribution control server DSV determines the control-target fixed terminal FS1 based on the information indicating the association between the terminal ID of the mobile terminal MS1 and the terminal ID of the fixed terminal FS1, and the operation contents Control for updating the content being displayed is executed according to the above. As a result, the fixed terminal FS1 displays the next page of the content being displayed and a page describing detailed information.

  On the other hand, as a result of the determination based on the content distribution policy, when the access destination of the access request transmitted from the fixed terminal FS1 corresponds to the restriction target, the content filter unit 73 controls not to relay the access request. To do. For example, if the access destination is the content server CS1, the access request is rejected without being transferred according to the content distribution policy shown in FIG. Therefore, a situation in which content including personal information of the user stored in the content server CS1 or information related thereto is displayed on the shared type fixed terminal FS1 without limitation is avoided.

  During execution of the above content distribution operation, in the distribution control server DSV, the ID linkage unit 71 uses the mobile terminal MS1 and the fixed terminal FS1 based on the location information of the mobile terminal MS1 sent from the location information server 17 of the mobile IMSNW1. The distance between is monitored. In this state, when it is detected that the mobile terminal MS1 has moved away from the fixed terminal FS1 by the preset distance or more, the ID link unit 71 moves the user U1 of the mobile terminal MS1 from the fixed terminal FS1 to another location. It is determined that the terminal ID of the mobile terminal MS1 and the terminal ID of the fixed terminal FS1 are associated with each other, and the corresponding content distribution policy stored in the distribution policy storage unit 72 is deleted.

  FIG. 23 shows a more specific configuration of the system according to the fifth embodiment described above. This system configuration uses a Web application server (Web AS) as the distribution control server DSV and the content distribution provider servers AP1 and AP2, makes the content filter unit 73 independent from the distribution control server DSV, and further uses a Web server as the content server. It is what was used. The Web AS and the SIP AS 15 of the mobile IMS, and the Web AS and the SIP AS 25 of the fixed IMS are both connected by an API using SOAP communication.

  24 and 25 are sequence diagrams showing the procedure of the content distribution operation in the system shown in FIG. In the figure, the position information of the fixed terminal FS1 is sent to and stored in the position information server 27 of the fixed system IMSNW2, and this position information is transmitted to the Web AS together with the fixed terminal ID by the SIP AS 25 of the fixed system IMSNW2. The transmission process of the fixed terminal position information is performed every time the installation position of the fixed terminal is updated.

  On the other hand, the location information of the mobile terminal MS1 is sent to and stored in the location information server 17 of the mobile system IMSNW1, and when the location information is updated as the mobile terminal MS1 moves, the updated location information is added to the SIP AS 15 together with the mobile terminal ID. Sent to Web AS. The Web AS selects the fixed terminal FS1 installed within a certain distance from the current position of the mobile terminal MS1, based on the received update position information of the mobile terminal MS1 and the installation position information of the fixed terminal. The terminal ID of the selected fixed terminal FS1 is associated with the terminal ID of the mobile terminal MS1. When the terminal ID association process is completed, the Web AS sends a content distribution policy setting request including a set of the associated fixed terminal ID and mobile terminal ID to the content filter unit 73.

  When the content filter unit 73 receives the content distribution policy setting request, the content filter unit 73 performs content for the fixed terminal FS1 based on the user profile information acquired from the user profile server 16 of the mobile IMSNW1 and information on the installation location of the fixed terminal. Set the delivery policy. Then, the content to be distributed to the user of the mobile terminal MS1 is selected based on the user profile information by the rating process, and the URL is responded to the Web AS.

  The Web AS notifies the content delivery request to the SIP AS 15 of the mobile IMS using SOAP based on the content URL. The SIP AS 15 notifies the content distribution request to the mobile terminal MS1 using SIP. In response to the content distribution request, when the user performs an operation for requesting content distribution in the mobile terminal MS1, the content request is sent from the mobile terminal MS1 to the content server CS1. As a result, the corresponding content data is transferred from the content server CS1 to the requesting mobile terminal MS1 and displayed.

  In parallel with the content push distribution process for the mobile terminal MS1, the Web AS transmits a content distribution request to the SIP AS 25 of the fixed IMSNW2 using SOAP. The SIP AS 25 notifies the content distribution request to the fixed terminal FS1 using SIP. When the fixed terminal FS1 transmits a content request in response to this content distribution request, the request is once received by the content filter unit 73.

  Using the screening function, the content filter unit 73 determines whether or not the access destination of the received content request is a restriction target with reference to the previously set content distribution policy. As a result of this determination, if the access destination is not a restriction target, the content request is transferred to the content server CS1. As a result, the content data is distributed and displayed from the content server CS1 to the fixed terminal FS1. This content data is also transferred after receiving the screening process of the content filter unit 73.

  Similarly, every time a content request is transmitted from the fixed terminal FS1, it is determined by the screening function of the content filter unit 73 whether the access destination of the content request is a restriction target. If it is not a restriction target, the content request is transferred to the content server CS1, and as a result, the content data is distributed and displayed from the content server CS1 to the fixed terminal FS1.

  On the other hand, it is assumed that an operation (for example, a link selection operation) for changing the access destination is performed in step 81 of FIG. Then, a content request is sent from the mobile terminal MS1 to the Aeb AS, and in response to this request, the corresponding content is transmitted from the Web AS to the requesting mobile terminal MS1 and displayed.

  At the same time, a content distribution request including an access destination URL is sent from the Web AS to the SIP AS 25 of the fixed IMSNW2 using SOAP, and the content distribution request is transferred from the SIP AS 25 to the fixed terminal FS1 using SIP. . When the fixed terminal FS1 transmits a content request in response to this distribution request, the content request is temporarily received by the content filter unit 73.

  In the content filter unit 73, the screening function determines whether or not the access destination of the received content request is a restriction target. As a result, if the access destination is a restriction target, the content data distributed from the content server CS1 is blocked from being transferred by the screening function of the content filter unit 73. Therefore, the content data is not transferred to the fixed terminal FS1. For this reason, a page including the user's personal information and related information is not displayed on the fixed terminal MS1.

  If the mobile terminal MS1 moves to another location in step 82 of FIG. 25 while the content is being displayed, the location information of the corresponding mobile terminal MS1 stored in the location information server 15 is updated, and this updated location is displayed. Information is transmitted from the SIP AS 15 to the Web AS together with the terminal ID. When the Web AS determines that the mobile terminal MS1 has moved away from the fixed terminal FS1 by a predetermined distance or more based on the notified location information of the mobile terminal MS1, the Web AS notifies the content filter unit 73 of the terminal ID of the mobile terminal MS1. And an instruction to release the association between the fixed terminal FS1 and the terminal ID of the fixed terminal FS1. As a result, the terminal ID association information between the mobile terminal MS1 and the fixed terminal FS1 and the content distribution policy corresponding thereto are deleted.

  As described above in detail, according to the fifth embodiment, since the API 75 is provided on the distribution control server DSV, the distribution control server DSV can communicate with both of the content distribution provider servers AP1 and AP2. As a result, each content distributor can distribute content to any fixed terminal among the plurality of fixed terminals FS1 to FSm of the fixed IMSNW2. That is, each content distribution company does not need to install and operate a dedicated fixed terminal, and can share a large number of public fixed terminals FS1 to FSm connected to the fixed system IMSNW2.

  Furthermore, since the APIs 81 and 82 are also deployed on the content distribution provider servers AP1 and AP2, each content distribution provider server AP1 and AP2 can extract and distribute content from any of the plurality of content servers CS1 and CS2. It becomes possible. That is, it becomes possible to separate the content holder and the content distribution provider.

  Further, the mobile terminals MS1 to MSn and the fixed terminals FS1 to FSm are associated with each other by their position information. For this reason, in cooperation with the mobile terminals MS1 to MSn and the fixed terminals FS1 to FSm, it is possible to perform various display processes such as switching of the content distribution destination and updating the page of the content being displayed.

  Further, based on the user profile information of the mobile terminals MS1 to MSn and the information indicating the installation status of the fixed terminals FS1 to FSm, a content distribution policy for the fixed terminals FS1 to FSm is set, and based on this content distribution policy, the content request Access is restricted. For this reason, for example, content including personal information of a user or information related thereto can be prevented from being displayed on a public fixed terminal that displays information to an unspecified number of people such as an electronic bulletin board. In addition, since the restriction process is performed in response to the access request, it is possible to more appropriately restrict the distribution of inappropriate content compared to the case where the restriction process is performed on the distributed content.

  Further, when the user of the mobile terminals MS1 to MSn moves away from the installation positions of the associated fixed terminals FS1 to FSm, information relating the mobile terminals MS1 to MSn and the fixed terminals FS1 to FSm and distribution policy information are automatically obtained. Erased. For this reason, when leaving the front of the fixed terminals FS1 to FSm, the mobile terminal user does not need to perform an operation to end the display of the content displayed on the fixed terminals FS1 to FSm.

(Other embodiments)
The present invention is not limited to the above embodiments.

The distribution control server DSV distributes content to a fixed terminal close to the position or area based on the position information. In this state, it is assumed that a user is operating the content distributed to the fixed terminal FSi by the mobile terminal MSi and another user operates the mobile terminal MSj to use the content distribution service. . In this case, the distribution control server DSV manages the service usage information of the mobile terminal MSi, and based on this management information, exclusively requests from other mobile terminals MSj that request content browsing on the fixed terminal FSi. To control. In this way, a specific user can exclusively use the content distribution service.

  On the other hand, when a certain user is operating the content distributed to the fixed terminal FSi by the mobile terminal MSi, when another user tries to use the content distribution service by operating the mobile terminal MSj, the distribution control server The DSV accepts a request from another mobile terminal MSj that requests content browsing at the fixed terminal FSi based on the service usage information by the mobile terminal MSi. Then, in addition to the content being distributed to the fixed terminal FSi, another content may be distributed, and for example, a multi-screen may be configured and displayed on the fixed terminal FSi in a composite manner. In this way, a plurality of users can use a single fixed terminal at the same time to browse content. That is, a plurality of users can use the content distribution service in cooperation.

  Other configurations of the mobile IMS network NW1, the fixed IMS network NW2, and the distribution control server DSV, the procedure and contents for the distribution control server DSV to acquire the location information and profile information of the mobile terminal from the mobile IMS network NW1, and the fixed system The procedure and contents of the selection process of the distribution destination fixed terminal and the session establishment process in the IMS network NW2 can be variously modified without departing from the gist of the present invention.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments.
