<p>A method for implementing service interaction in the IP multimedia subsystem is disclosed, wherein each service logic has an unique service identifier. The method includes the following steps: (a) service call session control function (S-CSCF) sends a session initiation protocol (SIP) request message to the application server (AP) to which an user request a service or to the service capability interaction manager (SCIM); (b) after the AS or SCIM has received the request and has executed this service, it inserts the service identifier of this service into the SIP request, and returns the SIP request with the service identifier to the S-CSCF. Most of the service interaction requirements are satisfied.</p> |
