METHODS AND APPARATUSES FOR SESSION CONTROL OF IMS SERVICES VIA A CS ACCESS BY USSD MESSAGES |
摘要 |
A system and method for allowing IMS subscribers to perform service and session control of IMS services via a CS access. A User Equipment, UE, that is registered with an IMS network but is not in a position to access the IMS network using IP can still access the IMS network and control the IMS sessions by sending Unstructured Supplementary Service Data, USSD, messages via an available Circuit Switched network that is connected to the IMS network. |
