The system shown in FIG. 1 includes an advanced service server group 10 that provides individual services, a signal distribution GW (Gateway) function unit 13 that handles only control signals, a GW function unit 14 that controls media and sessions, It comprises a subscriber SIP server 15, a callee subscriber SIP server 16, edge routers (ER) 19, 20, 21, a caller terminal 22, and a callee terminal 23. The advanced service server group 10 includes an application server 11 that manages services and a media server 12 that sends media (guidance).
The advanced service server group 10 is outside the network of the network provider, and includes a calling party SIP server 11, a called party SIP server 12, a signal distribution GW function unit 13, a GW function unit 14, and an edge router. (ER) 19, 20, and 21 form an IP network.

The first embodiment shows a specific control method in the case where the terminal of the operator A makes a call and guidance is necessary before providing the service.
First, when the calling terminal 22 makes a call, the calling subscriber SIP server 15 detects the call from the calling terminal 22. The calling subscriber SIP server 15 confirms the telephone number and the contract condition of the caller from the detected signal, and transmits a signal to the signal distribution GW function unit 13 if it is applicable. Next, when the signal distribution GW function unit 13 receives a signal from the calling subscriber SIP server 15, the signal distribution GW function unit 13 creates an ID (identifier) associated with the service and converts it into a signal connectable to the outside. Is transmitted to the application server 11 of the advanced service server group 10 outside. When receiving a signal from the signal distribution GW function unit 13, the application server 11 checks whether or not the calling terminal 22 needs guidance before connecting a call with its own service provision condition. As a result of the collation, when guidance is required, a signal with an ID associated with the service is transmitted to the media server 12.

  Here, an ID associated with a service (referred to as an association ID in the following embodiment) is a network identification ID, a server identification ID, a service type (identifier of what kind of guidance is sent), a calling side / destination side It is derived from a combination of a user identification ID (for example, a telephone number) and a service provision time, or is uniquely determined within the network.

  Similarly, the application server 11 transmits a signal to which the association ID is given to the calling subscriber SIP server 15 via the signal distribution GW function unit 13. The calling subscriber SIP server 15 includes the association ID in a control signal (for example, SIP) having a function of transmitting media, and transmits the control signal to the other GW function unit 14. The control signal is controlled only from the inside of the network, and even if a signal other than the requested control signal or an IP packet comes from outside the network, it is discarded on the edge router (ER) side, so that security is maintained. The media server 12 extracts the association ID from the control signal received from the GW function unit 14, compares it with the association ID already transmitted from the application server 11, and if they match, the originating terminal 22 of the operator C network After the session is established between the media server 12 and the media server 12, the guidance associated with the association ID is transmitted to the calling terminal 22.

  In parallel, the calling subscriber SIP server 15 connects to the called subscriber SIP server 16 according to the incoming call number. The called subscriber SIP server 16 connects to the corresponding called terminal 23 and notifies the calling subscriber SIP server 15 when it detects that the called terminal 23 has responded. The calling subscriber SIP server 15 notifies the media server 12 of the end of the guidance so that a call can be made between the calling terminal 22 and the called terminal 23 based on the notification, and the calling terminal 22 and the called terminal 23, a call path is set to 23, and a call is enabled.

(Second Embodiment)

The second embodiment shows a specific control method in the case where the terminal of the operator C makes a call and guidance is required before providing the service.
First, a terminal (not shown) of the operator C network makes a call. When connecting between networks, network identification IDs are negotiated in advance between operators, and network identification IDs exchanged in advance with each other are assigned to each call and distributed through the interface between providers, or from which provider Or the SIP-GW 17, the network identification ID is assigned to each call by the SIP-GW 17, and distributed to the called subscriber SIP server 16 through the relay server 18.

  The destination subscriber SIP server 16 makes a service provision determination based on the network identification ID and the telephone number of the destination terminal 23, and sends a connection request to the signal distribution GW function unit 13 if the service is provided. To do. Upon receiving the connection request signal, the signal distribution GW function unit 13 converts the signal into a signal connectable to the outside, and transmits this signal to the application server 11 of the advanced service server group 10 located outside. When receiving a signal from the signal distribution GW function unit 13, the application server 11 collates with its own service provision condition whether guidance is required for the calling terminal of the carrier C network before connecting the call. As a result of the collation, when guidance is required, a signal with an association ID is transmitted to the media server 12.

  Similarly, the application server 11 transmits a signal to which the association ID is given to the called subscriber SIP server 16 via the signal distribution GW function unit 13. The terminating subscriber SIP server 16 includes the association ID in a control signal (for example, SIP) having a function of transmitting media, and transmits the control signal to the other GW function unit 14. The control signal is controlled only from the inside of the network, and even if a signal other than the requested control signal or an IP packet comes from outside the network, it is discarded on the edge router (ER) side, so that security is maintained. The media server 12 extracts the association ID from the control signal received from the GW function unit 14 and collates it with the association ID already transmitted from the application server 11. After a session is established with the media server 12, guidance associated with the association ID is transmitted to the originating terminal of the operator C network via the SIP-GW 17.

  In parallel, the called subscriber SIP server 16 connects to the corresponding called terminal 23 according to the incoming call number, and notifies the operator C when it detects that the called terminal 23 responds. Based on the notification, the operator C notifies the media server 12 of the end of the guidance so that a call can be made between the originating terminal and the terminating terminal 23 of the operator C network, and the originating terminal of the operator C network. And a call path between the callee terminal 23 and the callee terminal 23 are set to enable a call.

The third embodiment shows a specific control method when the originating service and the terminating service compete. In the future service provision, when competition control between the calling side service and the called side service is required, the association ID is used when the called side advanced service server asks the calling side advanced service server to determine the competition.
As a main process, the arrival side advanced service server 26 notifies the calling side advanced service server 25 of the association ID of the service scheduled to be started at the arrival side terminal 32, and makes a service conflict determination to the originating side advanced service server 25. When determined, the calling side advanced service server 25 collates the association ID of the service already started on the calling side terminal 31 with the association ID notified from the called side advanced service server 26, and determines the service conflict.
If there is no conflict as a result of the determination, the arrival side advanced service server 26 activates the service scheduled to be activated on the arrival side terminal 32 and provides the service. If there is a conflict, start the service.
