Abstract

The invention provides a method for strengthening a common user identity in a converged network and a network unit for controlling the communication of users in the converged network, wherein the common user identity is shared by a group of users; the converged network at least comprises a first network unit and a second network unit, and when a user of the group of the users registers in the converged network, the first network unit acquires a configuration file of the user from the second network unit. The method for strengthening the common user identity in the converged network comprises the following steps: the first network unit checks if the acquired configuration file indicates the fact that if the user is a manager of the group of users; and if the acquired configuration file indicates the fact that the user is the manager of the group of users, the first network unit notifies the user of communication states of other users of the group of the users and/or authorizes the user to intervene the communication of other users.

Description

Strengthen the method and the NE of the shared public user identity in the UNE

Technical field

The present invention relates to the communications field, particularly, relate to the technology of the shared public user identity in the UNE that strengthens IMS for example.

Background technology

At present, IP Multimedia System IMS (IP Multimedia Subsystem) is the core technology of next generation network.IMS is based on the general-purpose platform of SIP (Session Initiation Protocol); Can support plurality of access modes fixing and that move simultaneously; Realize the fusion of fixed network and mobile network, its main feature is to have adopted Session Initiation Protocol, be independent of access and bearing technology.The framework of IMS mainly comprises:

-home subscriber server (HSS; Home Subscriber Server); It is except storage user's CAMEL-Subscription-Information and positional information; Also preserve and user-dependent, as to be used to handle Multimedia session customization data, comprise local information, security information (checking and authorization message), log-on message, Service Trigger Information, userspersonal information and distribute to user's S-CSCF etc.;

-CSCF (CSCF, Call Session Control Function), it mainly is responsible for handling the IP signaling in the multimedia call session process.Its function comprises: Multimedia session control, address transition and service negotiation served conversion etc.; CSCF further can be divided into: proxy CSCF (P-CSCF), inquiry CSCF (I-CSCF) and serving CSCF (S-CSCF); Wherein S-CSCF is the Centroid of SIP signaling plane; Effect is similar to the Softswitch in the soft switchcall server, selects the application corresponding type of server so that the user to be provided required business from home subscriber server (HSS) download user services configuration information and according to concrete service application;

-application server (AS), it is a SIP entity of holding and carry out service, is used as sip user agent to provide various 3G professional.

In IMS R6 version, introduced the shared public user identity (PUID) by 3GPP TS 23.228 definition, it makes a shared PUID to be associated with a plurality of subscriber equipmenies and can be registered simultaneously from a plurality of subscriber equipmenies that use different private user identity and different contact addresses.Each IMS core network subsystem user can have one or more public user identity, and the user uses this public user identity to ask to other user's communications.

The public user identity of being shared by a plurality of subscriber equipmenies is useful for the cooperation work pattern; For example service hotline, urgent call 911 etc., but current public user identity shared model can not satisfy the requirement of wherein dynamically being controlled this scene of cooperation by the keeper.Share in the PUID pattern existing, the keeper is counted as identical with other group memberships, and he can not know its group membership's operating state and in time for this group master control is provided.For example, the keeper of service hotline need know each group membership's operating state, and perhaps father and mother worry that its children chat with mobile phone or play games.In some cases, the keeper possibly hope ongoing calling is controlled, and for example appears in this calling or the like.

Summary of the invention

In order to solve above-mentioned the problems of the prior art; According to an aspect of the present invention; Proposed a kind of method that is used for strengthening the public user identity of UNE, wherein, said public user identity is shared by one group of user; Said UNE comprises first NE and second NE at least; As the user of this group among user during to said UNE registration, said first NE obtains this user's configuration file from said second NE, and said method comprises: whether the configuration file that said first NE inspection is obtained indicates said user is this group user's keeper; And, if this user of said configuration file indication is the keeper, other user's communications states and/or the communication of authorizing this user intervention said other user carried out of then said first NE in this group of this user notification user.

According to another aspect of the present invention; A kind of NE that is used for controlling the user's communications of UNE has been proposed; Wherein, public user identity is shared by one group of user, and said UNE comprises said NE and another NE at least; As the user of this group among user during to said UNE registration; Said NE obtains this user's configuration file, said NE from said another NE: the user identity testing fixture, and whether the configuration file that is used for checking the user who is registered to said UNE indicates said user is this group user's keeper; And; The user identity management device, being used for indicating said user at said user's configuration file is to this group of this user notification user's other user's communications states and/or the communication of authorizing said other users of this user intervention to be carried out under keeper's the situation.

Embodiment

The present invention proposes a kind of method that is used for strengthening the shared public user identity of UNE, said UNE is meant here and moves and the fixing and fusing network.For example basic thought of the present invention is described below, promptly, in the PUID that shares, is introduced administrator role through the user's in the home subscriber server (HSS) configuration file is made amendment with reference to the IMS framework of Fig. 1.For example, can be to the modification of user profile based on carrying out with the prior contract of signing of user.

As shown in Figure 1, when utilizing, the keeper among one group of user shares PUID (being hotlineims.service.com in this example) when being registered in the IMS network, and S-CSCF is known its keeper's identity according to keeper's indication, here is keeper UE#1.Therefore, S-CSCF notifies this group membership's state to UE#1 at once.UE#1 can also control the calling that its group membership carries out, and for example adds this calling, interrupts this calling, forwards the call to the another UE, plays bell sound, music or prompt tone or the like.

Preferably, keeper's indication can be added in the configuration file that is stored in the user among the HSS.Fig. 2 a shows the uml model of the common identity class of definition among the 3GPP TS 29.228.Should be pointed out that in the IMS network public user identity can make the request of being used for and other telex networks by Any user, it can be SIP URL (SIP URL) or TEL URL (phone URL).When public user identity comprised SIP URL, it taked for example following form: sip:first.lastoperator.com usually.The TEL URL that comprises the telephone number of representing international format when public user identity is when (being used for the intercommunication with pstn telephone), and it takes for example following form: tel:+1-212-555-0293 usually.Shown in Fig. 2 b, the present invention has added new keeper's indication in this uml model.

Particularly, according to 3GPP TS 29.228, the user profile that transmits through Cx interface can be the form shown in Fig. 3 a and 3b.Shown in Fig. 3 a, preferably, new keeper's designator is added in the common identity data field.For example, the service provider can be in the common identity data field through keeper's indication being made as TRUE or FALSE indicates whether this user is the keeper.At the UE period of registration, S-CSCF is from HSS download user configuration file.Therefore, S-CSCF will know whether this UE is the keeper.If then S-CSCF will give the keeper and can for example control its communication based on keeper's indication with the status report of other UE of identical PUID registration.Under the situation shown in Fig. 3 b, a user has a more than PUID, and if desired, the user can create to each PUID and share the PUID group.Keeper's designator in the common identity data field of preserving among the HSS can be so that the IMS network be known the administrator role of this UE in each shared PUID group.For example, the UE#2 among Fig. 1 and its children share another PUID, so he is the keeper in this shared group.

The method of the shared public user identity that is used for strengthening UNE is according to an embodiment of the invention described with reference to Fig. 4 below.The method of present embodiment goes for for example front system shown in Figure 1, being described in this and no longer repeating about said system.

In step 401, whether the user's that the inspection of first NE is obtained configuration file indicates this user is one group of keeper among the user.Here, said first NE for example can be the S-CSCF among Fig. 1.As noted earlier, in the present embodiment, said public user identity PUID is shared by this group user, when the user among this group user when UNE is registered, said first NE obtains this user's configuration file from second NE.Here, said UNE for example can be the IMS network like Fig. 1, and said second NE for example can be the HSS among Fig. 1.

Particularly; For example can be for IMS network shown in Figure 1; UE#1, UE#2 and UE#3 are registered to the IMS network with public user identity hotlineims.service.com; Wherein UE#1 is the keeper among this group user, for example through the indication of the keeper in the common identity data field of configuration file is made as keeper's identity that TRUE indicates UE#1.

In step 402, be the keeper if this user's configuration file is indicated said user, other user's communications states and/or the communication of authorizing this user intervention said other user carried out of then said first NE in this group of this user notification user.Particularly, according to embodiments of the invention, when UE#1 was registered to the IMS network, S-CSCF obtained its configuration file from HSS, and identified keeper's identity of UE#1 according to this configuration file.Therefore, S-CSCF can notify its group membership's state to UE#1.As shown in Figure 1, its group membership UE#2 of I-SCSF notice UE#1 just converses with telephone number 0016309791234, and UE#3 just is being warned the new calling from VIP.UE#1 also can intervene its group membership's communication, and for example UE#1 can initiate to the calling of UE#3 or send a message to UE#3 to remind UE#3 to call out extremely important, and if desired, UE#1 can also appear in the calling of this and VIP.

Should be understood that; For example can know to the communication that UE#1 notifies its group membership's state or authorizes UE#1 to intervene its group membership under the situation of its keeper's identity and carry out the communication of perhaps notifying its group membership's state or authorizing its group membership of its intervention for it to the S-CSCF request automatically by UE#1 by S-CSCF.

Can know through above description; Adopt the method for shared public user identity that is used for strengthening UNE of present embodiment; Can dynamically control its group membership's communication through in the one group of user who uses common identity, introducing the keeper; The call state that is its group membership can be kept watch on and controlled by the keeper, this thereby strengthened current IMS standard.The Administrator Level can for example be limited the service provider; And the service provider can provide management service for the keeper through existing service point triggers and other services, and for example TS 24.141 exists service, TS 24.147 conference service, TS 24.247 message to transmit service or the like.

The method according to the embodiment of the invention of should be pointed out that can be applied to adopt existing and any agreement in the future, the UNE of standards and norms, such as but not limited to foregoing IMS network.

Explain how will be applied to for example IMS network with signaling process figure below according to the method for the embodiment of the invention.Fig. 5 a, 5b and 5c show the signaling process of application example according to the method for the invention.

Fig. 5 a shows the signaling process that when keeper UE registers, activates keeper's service.Step 1 is to 5 being UE register information flow of standard, specifically can be with reference to 3GPP TS 23.228 IPMultimedia Subsystem (IMS), at this not to its detailed description.In step 6, S-CSCF checks filter criteria, because this UE has management function, i.e. keeper's indication is made as TRUE, so S-CSCF will trigger " state reservation request " to management service application server (AS).Should be pointed out that this application server AS is meant logic entity here, it can integrate with S-CSCF or separate with S-CSCF.In step 7, S-CSCF is sent to AS with " state reservation request ".In step 8, AS carries out necessary authorization check and is authorized to use service to guarantee this user.In step 9,10 and 11, AS sends and responds to UE.In

step

12,13 and 14, in case completion status is subscribed, when the state of other UE in sharing the PUID group changed, AS was updated to keeper UE with regard to transmit status.Therefore, the call state of other UE can be kept watch on and control by keeper UE.In addition, from AS to UE " state notifying ", comprising calling ID, this calling ID can be used for controlling ongoing calling by keeper UE.Other information also can be included in " state notifying " according to the configuration of keeper UE, for example call out when replied, which side is the calling party or callee or the like.

Fig. 5 b shows keeper UE and sends " state reservation request " to change the signaling process of configuration according to its needs.As shown in the figure, when keeper UE was registered to the IMS network, it can select to send to from AS its state information type.

Fig. 5 c shows its group membership's of keeper UE control ongoing calling signaling flow process.In step 1, keeper UE sends " call operation request " to P-CSCF.Should be pointed out that P-CSCF comprise by the predefined operation code of service provider in order to the indication should be to the operation of taking by the specified calling of the calling ID in " state notifying ".The operation that the service provider provides it to take calling for keeper UE; For example interrupt call, diverting call to another user, add calling, monitored call, only with call out in square tube words, add other UE in call out, perhaps play bell sound, music or prompt tone or the like.In step 2, P-CSCF transmits " call operation request " to S-CSCF.In step 3, S-CSCF checks filter criteria, because this UE has management function, i.e. keeper's indication is made as TRUE, so S-CSCF will trigger " call operation request " to management service application server (AS).In step 4, S-CSCF sends " call operation request " to AS.Should be pointed out that service control logic can realize in the AS of indication S-CSCF executable operations logic.In step 5, use by the specified associative operation logic of operation code, AS indication S-CSCF accomplishes should

operation.In step

6,7 and 8, AS sends and responds the UE to the keeper.In step 9,10 and 11, state upgrades and is sent to keeper UE.
