Step 701: The service request unit establishes a first call with the first service control unit, where the first service control unit is located in a signaling path of the first call. In this step, the terminal and/or the HTTP client save the terminal access network. The dialog of the first call; Step 702: The user clicks the HTTP page displayed on the user terminal to initiate a SIP second communication request, where the request carries the session identifier of the first call that the terminal accesses the network, and the session identifier of the first call of the terminal accessing the network may be It is from the network preset attached to the HTTP page, or it can also be saved from the user terminal;

Further, the SIP request may further carry an AS address of the terminal accessing the network, that is, the first service control unit address; Step 703, the service triggering unit receives the SIP second communication request, and obtains the address of the first service control unit;

The service triggering unit may obtain the first service control unit address according to the session identifier of the first call carried in the SIP second communication request, for example: when the SIP second communication request is a re-INVITE re-invitation message. The service triggering unit may obtain the first service control unit address according to the established signaling path of the first call according to the session identifier of the first call;

In addition, the service triggering unit may obtain the first service control unit address by using other methods, for example, when the first service control unit address has been carried in the SIP second communication request, the service triggering unit may obtain the first request from the request. a service control unit address; or, the service triggering unit may obtain the first service control unit address according to the iFC performing matching according to a conventional manner;

Step 704: The service triggering unit sends a SIP second communication request to the first service control unit address. Step 705: The first service control unit provides logical control of the request service.

In this step, the first service control unit may apply the request service to the first call according to the session identifier of the first call carried in the received SIP second communication request.

In this embodiment, the step 702, the AS address of the terminal accessing the network carried in the SIP request, or another service control unit, that is, the second service control unit address, in step 703, the service triggering unit After receiving the SIP second communication request, the SIP second communication request may be sent to the second service control unit address, and then the AS signaling path of the first call is processed; or, after step 705, the service triggering unit is After the AS signaling path of the first call is processed, the SIP second communication request is sent to the second service control unit address. In addition, after step 705, the first service control unit may also cull the signaling path of the first call by itself, and the specific steps are: the SIP request message returned by the first service control unit to the service triggering unit. The Record-Route header field no longer carries its own address, and the service triggering unit culls the signaling path of the first call.
