Abstract: 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 VLR2 where a new LAI is located; VLR2 receiving 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 VLR2 to VLR1 where original LAI is located; VLR1 receiving the location cancellation message forwards a received non-call service request to VLR2; VLR2 processes the received non-call service request, and transmits a processing result to VLR1; and VLR1 transmits 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.

Abstract: 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.

Abstract: Described is a releasing method for a conference, and the method includes: when it is determined that a participant leaves the conference, media resources of the conference which are related to the participant are released, and a sponsor of the conference is notified to release a transaction identifier used by the participant during the conference A releasing device and system for a conference, and a computer storage medium are further provided.

Abstract: Provided are a method, device and system for realizing visual identification. A visual identification device learns a visual identification feature of an identified device, and performs visual identification on the identified device accordingly. Thus automatic identification of the device is realized in a visual manner, and the unified manipulation on multiple identified devices can be easily realized.

Abstract: Provided are a method and device for sending identifier information or a call transfer request. The method for sending a call transfer request includes: determining that a call for which a UE initiates a transfer in a PS domain to a CS domain includes an emergency call; acquiring identifier information of an EATF to which the UE is anchored when initiating the emergency call; and initiating transfer of the emergency call of the UE in the CS domain according to the identifier information. By means of the technical solution, the problem that an emergency call cannot be transferred in a case of networking of multiple service domains is solved, and the effect of ensuring that transfer of the emergency call can be completed is further achieved.

The method includes that UE transmits a location updating request to VLR2 where a new LAI is located; VLR2 receiving 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 VLR2 to VLR1 where original LAI is located; VLR1 receiving the location cancellation message forwards a received non-call service request to VLR2; VLR2 processes the received non-call service request, and transmits a processing result to VLR1; and VLR1 transmits 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
