摘要:
A method for implementing a chairman side conference service of an IP Multimedia Subsystem centralized service is disclosed. A non ICS UE has contracted a conference service and is currently in calls with multiple UEs. The method for implementing the conference service when the non ICS UE serves as a chairman UE comprises: the chairman UE originating a conference setup request to an eMSC; after receiving the request, the eMSC sending a session request message for setting up the conference service to a conferencing server according to the address of the conferencing server to which the chairman UE belongs; the conferencing server returning a success response message to the eMSC; after receiving the response, the eMSC inviting the UEs, which are currently in calls with the chairman UE, to participate in the conference, and returning a conference setup success message to the chairman UE after the participation is successful.

The present invention discloses an emergency service handover method which is applied in a single radio voice service system. A UE has established an emergency session between an IMS domain and an emergency call center via LTE/SAE network, wherein the emergency session is anchored to a service centralization and continuity application server, SCC AS, at a visited location. When MSC obtains information that the UE having established the emergency session needs to be switched to a CS domain, an enhanced MSC initiates a session establishment request to the visited SCC AS for performing a handover from the IMS domain to the CS domain on a service layer.

The present invention provides a method, a device, and a system for realizing a registration mechanism of an IP multimedia subsystem. In the above method, a S-CSCF obtains a private user identity and a public user identity of CS UE and characteristic information of a MSC Server from a received request message, wherein the request message includes a registration request or a de-registration request; and then matches the obtained private user identity, public user identity, and characteristic information with existing registration binding relationships. If the match is successful, an operation indicated by said request message is performed on the successfully matched registration binding relationship. Based on the solution proposed in the present invention, the logic of the registration service can be ensured to be normal.

A late call forwarding method in the IMS centralized service. During a call setting up, an ICCF receives a call request from the CSCF serving the called user, called session A, and the ICCF acquires a called user's roaming number and initiates a call to the called user. After receiving the call request, the VMSC serving the called user triggers the late call forwarding service according its determination. A CAMEL service is triggered when the VMSC initiates a call to the forwarding target. The VMSC exchanges messages with the ICCF and informs the ICCE about session associated information and the forwarding reason. When the ICCF determines that the forwarding is needed, it sends a response to the session A does not send the response message, after a telecom application server (TAS) receives the indication, the TAS initiates a regular forwarding service.

A method is provided for realizing session transfer, comprising: a service continuity application server (SCC AS), after receiving a session transfer request, when judging that a state of a session needed to be transferred is in a held state, updating a remote leg by using a held state session state information, and notifying an enhanced mobile switching center (eMSC) that the state of the session needed to be transferred is the held state; and the eMSC completing a call setup of a target access network according to the held state. A system is also provided for realizing session transfer. The method and system can realize correct transfer of a held state voice session, realize correct service logic and improve user experience.
