Hereinafter, a multi-party call service method and a charging method according to the third generation mobile communication network according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a system configuration diagram to which the method of the present invention is applied and includes a base station 12 that communicates using a wireless section with wireless mobile terminals 10a to 10n; A control station (14) connected to the base station (12) to control the radio link and the wired link and to maintain the continuity of the call while the subscriber is moving; An exchange station (16) connected to the control station (14), constituting a subscriber's call path, and connecting to another communication network (for example, the Internet network) through an interworking function module (not shown); All permanent information of the wireless mobile terminal (eg, terminal information (NIM, ESN), subscriber information, additional service information required for connecting an incoming call to the wireless mobile terminals 10a to 10n or providing other mobile communication services). A home position register 18 storing the home position register 18; A billing server 20 for billing calls between subscribers; And a short message server 22 which receives a short message input by the wireless mobile terminal of the multi-party call service subscriber (for example, a short message indicating transfer of session authority and billing authority) and delivers it to a corresponding party. Equipped.

At least one of the users using the wireless mobile terminals 10a to 10n is a subscriber to a multiparty call service having session rights and billing rights.

The home location register 18 stores an internal subscriber database for processing various messages, location registration and deletion, subscriber information processing, error recovery, call processing, and additional services related to subscriber service requested by the switching center 16. Inquire or update.

2 is a flowchart illustrating a multi-party call service operation and a charging operation according to the third generation mobile communication network according to an embodiment of the present invention.

First, a subscriber subscribed to the multiparty call service generates a call with a remote party in turn in a multiparty session with session authority and charging authority (step S10). That is, when a user having a wireless mobile terminal 10a is a multi-party call service subscriber, the multi-party call service subscriber uses the wireless mobile terminal 10a to make an outgoing call to a wireless mobile terminal of a remote party located at a remote location. 12). The outgoing call is transmitted to the switching center 16 through the control station 14, and the switching station 16 contacts the corresponding party based on the subscriber's terminal information (e.g., a telephone number) stored in the home location register 18. Connect the incoming call.

In this way, the multi-party call service subscriber establishes a session with a plurality of remote parties and performs a call (step S12). At this time, the session right and the billing right belong to the multi-party call service subscriber, that is, the session establisher. And, the charging server 20 assigns an ID number to the remote counterpart in the order of joining the session. That is, the billing server 20 first assigns an ID number of "# 1" to a remote party who has joined the session, and secondly assigns an ID number of "# 2" to a remote party of the session. do. The ID assignment in the billing server 20 is for maintaining billing to the designated remote party when the multi-party call service subscriber wishes to leave the session later.

When the conference call subscriber tries to leave the session during the call, that is, when he tries to release his call (“Yes” in step S14), the conference call subscriber transfers his or her session rights and billing rights. The remote counterpart to be specified is specified (step S16). For example, the multi-party call service subscriber inputs a short message indicating that the session authority and the charging authority are transferred to the telephone number of the wireless mobile terminal of the person to be transferred by operating his wireless mobile terminal. Of course, in order to input a short message, a lot of time may be required according to the character key input. Therefore, it is only necessary to enter a phone number of the wireless mobile terminal of the person to be transferred. In this case, a special key (eg * Key or # key, etc.)

The predetermined short message (e.g., * 011-111-2222 #) containing the telephone number of the keyed wireless mobile terminal to be transferred is shorted via the exchange station 16 through the base station 12 and the control station 14; Is sent to the message server 22. The short message server 22 grasps the input short message as a short message related to billing and transmits the telephone number (011-111-2222) of the wireless mobile terminal in the short message to the subscriber database in the home location register 18. (Step S18).

The subscriber database in the home location register 18 updates the session right and the billing right based on the entered telephone number. That is, the database in the home location register 18 transfers the session right and the billing right that were in the multi-party call service subscriber to the user of the wireless mobile terminal corresponding to the input telephone number (011-111-2222) (step S20). ).

When the renewal of the session right and the billing right is completed, the home location register 18 provides the billing server 20 with information (for example, a phone number) about the person who has been transferred the billing right. Allow billing to continue for

In addition, the home location register 18 requests the short message server 22 to generate the short message indicating that the session right and the billing right have been transferred through the switching center 16 as the renewal of the session right and the charging right is completed. do. The short message server 22 generates a corresponding short message and transmits it to the user's wireless mobile terminal (telephone number 011-111-2222) to which the session right and the billing right have been transferred (step S22).

Accordingly, the user (remote party) who has transferred the session right and the billing right has a predetermined short message displayed on the display panel of his wireless mobile terminal (eg, "session right and billing right to you for the current call"). Has been transferred ", etc.) and acknowledges that session and billing rights for the current session have been transferred to you.

Thereafter, even if the multi-party call service subscriber who transfers the session right and the billing right leaves the session, that is, the call is released, the call in the session continues to be connected, and the billing server 20 charges the session. It continues (step S24, S26).

Here, the remote counterpart who has transferred the session right and the charging right may also transfer the session right and the charging right to another remote counterpart.

On the other hand, in the above-described embodiment of the present invention, when the multi-party call service subscriber designates the remote party, the session right and the charging right are transferred unconditionally, but the remote party receiving the previous notification information on the session right and the charging right The transfer of the session authority and the charging authority may be completed only when the acknowledgment signal for transferring the session authority and the charging authority is transmitted to the home location register 18. In this case, it is highly likely that all of the call charges for the multilateral call service subscriber will be transferred to the transferer.However, the call charges due to the charge until the transfer of the session right and the charge right of the multilateral call service subscriber are completed. The payment should be made by the subscriber of the call service.

As described in detail above, according to the present invention, even if the multi-party call service subscriber terminates the call, if the multi-party call service subscriber transfers his or her session authority and billing authority to a remote party, the session established by the multi-party call service subscriber is established. Continuity is ensured for calls that participate in and billing for that session continues.

On the other hand, the present invention is not limited only to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, the technical idea to which such modifications and variations are also applied to the claims Must see
