Abstract

PURPOSE: A caller information display service system and method using a gateway are provided to display various display information designated by a caller on a terminal of a callee. CONSTITUTION: A subscriber registers display information desired to be display on a terminal of a callee for a display information server(S51). It is checked whether a call is generated from a caller(S52). An HLR(Home Location Register) searches subscriber information for a corresponding callee to check whether he/she has been subscribed for a caller information display service and the service has been activated(S53). If so, the HLR requests routing from a gateway and the gateway generates a call with an origination MSC(Mobile Switching Center)(S55). The HLR receives routing information required for call setup to a destination MSC from the gateway(S56). The gateway receives display information from the display information server and transmits it to the destination MSC(S57). The destination MSC pages a destination terminal through a BSC(Base Station Controller) and displays the display information(S58). A caller phone number and the display information are continuously displayed until a callee answers(S59). When the callee answers, the operation of displaying the caller display information is stopped(S61). A speech path is formed between the caller terminal and the callee terminal(S62).

The service performing operation of the caller information display service system using the gateway 20 according to the present invention having the above-described configuration will be described in detail with reference to FIGS. 4 and 5 as follows.

First, in order to receive the above-mentioned caller information display service, the caller information display service provided by the mobile service provider must be subscribed and the service must be activated. The information is managed by the home location register 15 as in the prior art.

In addition, in order to be provided with various display information as in the present invention, the caller's phone number on the display information server and display information to be displayed together with the phone number, for example, the caller's name (or nickname, etc.), an image, a ringtone, an emoticon, an avatar At least one piece of information such as text (business card information, etc.) must be registered, and it must be able to be managed. In this case, a method of registering and managing display information is performed through the ARS device 40 and contents supply. It may be divided into a method performed through the device 50.

Here, the method of registering and managing the display information through the ARS device 40, after the subscriber registered in the caller information display service accesses the ARS device 40, the ARS device 40 according to the guidance of the communication terminal Register the display information stored in the memory in the display information server 30, modify, delete, edit the display information registered in the display information server 30, or display the display information to be displayed along with the actual caller's telephone number among various display information. Means to perform management operations such as selecting information.

In addition, the method of registering and managing display information through the content supply device 50 includes a subscriber registered with the caller information display service connected to the content supply device 50 through the Internet, and then the content supply device 50. Produces display information to be displayed together with the caller's telephone number by using the display information production function provided by the registered information in the display information server 30, and corrects, deletes and edits the display information registered in the display information server 30. Or to select display information to be displayed together with the actual caller's telephone number from various display information.

At this time, the connection between the ARS device 40 or the content supply device 50 and the display information server 30 is connected through an external interworking processor 34 based on the TCP / IP protocol, and the caller is connected through the connected devices. The phone number and the display information to be displayed together with the phone number are received and stored in the DB processing unit 31 to register the display information for each subscriber.

In this way, if the subscriber is subscribed to the caller information display service and the service information is activated, the display information to be displayed on the called party's terminal together with the caller's telephone number is registered in the display information server 30 (step S51). A subscriber information display service is provided to a subscriber according to an operation procedure described below.

That is, as an arbitrary caller attempts to make a call to any called party using his or her communication terminal, it is checked whether an incoming call is generated from the calling party (step S52), and when an incoming call occurs, the calling side exchange 10a returns to the home position. A location request message (LOCREQ; LOCation REQuest message) is transmitted to the register 15 to request location information on the called party.

At this time, the home location register 15 receiving the location request message checks the subscriber information for the corresponding called party and checks whether the service is activated and the service is activated (step S53). If the caller information display service is not subscribed to or the service is not activated, the call is made with the called exchange according to the general call processing procedure (step S54).

However, when the caller information display service is subscribed and the service is activated, a routing request message (ROUTREQ; ROUTRE REQUEST message) is transmitted to the gateway 20 to provide the caller information display service according to the present invention. In this case, the gateway 20 transmits the reception information (TLDN) for call setup to the home location register 15 using a routing response message (routrsp) in response to the routing request.

Accordingly, the home location register 50 receiving the routing response message transmits the incoming information received from the corresponding gateway 20 as a response to the location request of the originating exchange 10a, wherein the incoming information is transmitted to the location response. The message is transmitted to the originating exchange 10a by using a location response message (locrsp).

Then, the source exchange 10a transmits an IAM (Initial Address Message) message including the incoming information to the gateway 20, and the gateway 20 receiving the corresponding IAM message transmits an address complete message (ACM) message. By transmitting to the originating exchange 10a, a call is generated with the originating exchange 10a (step S55), and a location request message (LOCREQ) to the home location register 15 for call setup to the actual called party terminal side. ) To request the location information for the called party. In this case, the gateway 20 transmits a service flag indicating that the message is transmitted by the gateway 20 to provide the caller information display service.

After receiving the location request message, the home location register 15 confirms that the service flag included in the location request message and the caller information display service in the subscriber information are activated, and then requests routing to the actual destination side exchange 10b. In response to the routing request, the destination exchange 10b includes the destination information (TLDN) for setting up a call, that is, routing information about the called party, in the routing response message (routrsp). The home location register 15.

Accordingly, the home location register 15 receiving the routing response message includes the incoming information in the location request message and transmits the received location information to the gateway 20 so as to transmit the routing information necessary for the call setup from the gateway 20 to the destination exchange 10b. The gateway 20 receives the display information to be displayed on the called party's terminal by transmitting a service request message (SERVREQ) to the display information server 30 (step S56).

That is, when the gateway 20 transmits a service request message including the caller's phone number to the display information server 30, the display information server 30 corresponds to the caller's phone number through the internal DB processing unit 31. After extracting the registered display information, name (or nickname, etc.), image, ringtone, emoticon, avatar, text, etc. corresponding to the caller's phone number, the corresponding display information is used as a response to the service request. servrsp (service response message) is included in the transmission to the gateway 20. At this time, when there is a large number of display information registered in correspondence with the caller's telephone number, the display information designated by the caller is extracted therefrom and transmitted to the gateway 20.

Thereafter, the gateway 20 receiving the service response message from the indication information server 30 transmits an IAM message including the called information to the called side exchange 10b for establishing a call with the called side exchange 10b. At this time, the indication information received from the indication information server 30 is included in the IAM message and transmitted to the destination side exchange 10b (step S57).

The receiving side exchange 10b receiving the IAM message including the incoming information and the indication information transmits a PAGERE message (PAGEREQ) to the base station controller in order to allocate a wireless channel with the called terminal. Accordingly, the base station controller allocates a radio channel to the called party terminal through the base station, and transmits a paging response message (pagersp) to the called side exchange 10b.

Then, the destination exchange 10b generates one call with the gateway 20 by sending an ACM message to the gateway 20, and also includes a setup message including call setup information for setting up a call to the actual called party terminal. (SETUP message) is transmitted to the base station controller to request the incoming call setup, at which time the base station controller responds to the incoming call setup request using the call configuration message (CALLCONF; CALL CONFiguration message), the incoming call after the timer is started It waits for the resource allocation request from the side exchange 10b.

Accordingly, the destination exchange 10b transmits a channel assignment request message (ASSIGNREQ; ASSIGNment REQuest message) to request a radio channel resource allocation to the base station controller, where the caller's telephone number and indication information corresponding to the telephone number are sent. The base station controller transmits a ring signal to the called party's terminal by transmitting a channel assignment request message including the calling party's telephone number and indication information to the base station, and simultaneously transmits the corresponding calling party information to the called party's terminal. Therefore, the caller's telephone number and display information corresponding to the telephone number, that is, a name (or nickname, etc.), an image, a ringtone, an emoticon, an avatar, or a text corresponding to the caller's telephone number, are displayed on the display unit of the called party's terminal. Step S58).

In addition, the base station controller transmits a channel assignment complete message (ASSIGNCOMP; ASSIGNment Complete message) to the destination exchange 10b when the base station controller receives a report that the channel allocation is completed from the corresponding base station after transmitting the channel assignment request message to the base station. After that, an ALERTing message indicating that the ring signal is being transmitted to the called party terminal is transmitted to the called side exchange 10b.

In this state, the called party's telephone number and display information are continuously displayed on the display unit until the called party answers the call (steps S59 and S60).

After that, when the called party answers the call, the called terminal stops displaying the corresponding caller indication information (step S61). At this time, the incoming call of the called terminal is reported to the base station controller through the base station. The CONNECT message corresponding to the incoming response of the terminal is transmitted to the called side exchange 10b.

Then, the destination exchange 10b transmits an ANM (ANswer Message) message indicating the incoming response to the gateway 20, and the gateway 20 transmits the corresponding ANM message back to the source exchange 10a. A call path is formed between the terminal and the called party's terminal to enable the call (step S62).

On the other hand, the embodiment according to the present invention is not limited to the above, it can be carried out by various alternatives, modifications and changes within the scope apparent to those skilled in the art with respect to the present invention, for example A subscriber who is subscribed to the caller information display service in the home location register and additionally manages a parameter indicating whether or not the display information is registered for the subscriber whose service is active, thereby providing a general caller information display service subscriber and caller information display service according to the present invention. Call processing is performed by distinguishing subscribers, thereby providing an appropriate caller information display service.

In addition, in the above-described embodiment, the gateway and the display information server have been described in a separate structure, but this can be implemented using only one system, for example, a gateway, in which case the gateway manages the display information managed by the display information server as its own database. Therefore, when the display information corresponding to the calling party's telephone number is to be transmitted to the destination exchange, the present invention is searched for its own database without transmitting a service request to the display information server, and the corresponding information is transmitted to the destination exchange. It is possible to provide a caller information display service according to.

As described above, the present invention registers a variety of display information for each subscriber in a separate display information server rather than a communication terminal or a home location register in relation to the caller information display service, and through the gateway to the corresponding caller information display service subscribers. By performing the call processing, it is possible to display not only the caller's telephone number but also specific display information designated by the caller through the gateway on the called party's terminal with minimal modification to the exchange equipment in connection with the caller's information display service. By registering in a separate display information server it is possible to provide the desired caller information display service to the existing communication terminal.
