A non-call service processing method, apparatus and system in a Circuit Switch Fallback (CSFB) system are provided. The method includes that UE transmits a location updating request to VLRwhere a new LAI is located; VLRreceiving the location updating request transmits a location updating request to a HLR; the HLR receiving the location updating request transmits a location cancellation message carrying an address of VLRto VLRwhere original LAI is located; VLRreceiving the location cancellation message forwards a received non-call service request to VLR; VLRprocesses the received non-call service request, and transmits a processing result to VLR; and VLRtransmits the received processing result to the HLR or a GMLC which transmitted the non-call service request. Thus the interruption of a non-call service can be avoided, and the normal use of UE can be ensured.

Non-call service processing method, apparatus and system in circuit switch fallback system

The present invention discloses user equipment, a home subscriber data server (HSS) and a method and system for obtaining user equipment ability by a core network element. Wherein, the method for obtaining user equipment ability by the core network element includes: in and/or after the IP multimedia network subsystem (IMS) registration process, the home subscriber data server (HSS) informing the IMS network element of the ability information of user equipment (UE). The HSS is enabled to obtain the user equipment ability information in present invention, and can provide services for various operations of subscribers.

Method and system for obtaining user equipment ability by user equipment, home subscriber data server and core network element

The present application discloses a method and a system for implementing domain selection during a terminated call, in which an application server (AS) sends, according to a received call request message, a query request message to a home subscriber server (HSS); the HSS queries, according to the query request message, a packet switching (PS) domain mobility management network element to obtain information of a called terminal and/or a network accessed by the called terminal in the call request message; the HSS feeds back the obtained information of the called terminal and/or the network accessed by the called terminal to the AS; and the AS selects a domain to which a call message is to be routed according to the information of the called terminal and/or the network accessed by the called terminal.

Method and system for implementing domain selection during the terminated call

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.

Method, system, and device for realizing registration mechanism of IP multimedia subsystem

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.
