  • Patent number: 8433282
    Abstract: 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.

  • Patent number: 8363645
    Abstract: A method for implementing call forwarding on user-determined user busy, including the following steps of: step 1: after receiving a session request routed by a CSCF from a calling side (401, 402), an IMS Circuit Switched Control Function (ICCF) on a called side establishing a call with a called terminal having IMS Centralized Service (ICS) capability (403), and then the called terminal ringing (410); step 2: sending, by the called terminal, a user-determined user busy message to the ICCF when a called user rejects the call (404); and step 3: notifying, by the ICCF, a Telecom Application Server (TAS) that the called terminal is in a user-determined user busy state (405), and the TAS initiating a procedure of call forwarding on user-determined user busy (406). A method for releasing the established media resources resources and session is also provided.

  • Patent number: 8339999
    Abstract: 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.

  • Patent number: 8289887
    Abstract: 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.

  • Publication number: 20120178466
    Abstract: The present invention discloses a home NodeB access method comprising: during initialization, a home NodeB access point selecting a home NodeB gateway connected to one of core networks which the home NodeB access point has right to access as a serving home NodeB gateway; the home NodeB access point registering in the serving home NodeB gateway, registering user information with the serving home NodeB gateway after receiving a non-access layer message sent from a user equipment, and forwarding the non-access layer message to the serving home NodeB gateway; and the serving home NodeB gateway forwarding the non-access layer message to a core network corresponding to a network access identifier of the user equipment according to the identifier after receiving the non-access layer message; and the core network interacting with the user equipment to complete access of the user equipment; so as to achieve share of the home NodeB.

  • Patent number: 8180347
    Abstract: A domain transferring method for the single radio voice call continuity, a UE accesses via an LTE/SAE network, and sets up an IMS session anchored at a VCC AS with a remote node; when an S-IWF receives a handover request used to transfer the session to make the session access from a CS domain, the method comprises: the LTE/SAE network sends a handover command to the UE, the UE sends a handover complete message to a target access device after receiving the handover command; after the UE sends the handover complete message, or after the S-IWF receives the handover complete message, a release session notification message is sent to a VCC AS; after receiving the session release notification message, the VCC AS releases the session resources of the session.

  • Publication number: 20110145388
    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.

  • Publication number: 20110009121
    Abstract: A method for user equipment realizing handover across access networks in active state includes: during the process for a user equipment in active state handing over from an evolved packet system to a universal mobile telecommunications system or a global system for mobile communications, an evolved universal mobile telecommunication system radio access network notifies the user equipment whether this handover is a handover due to an incoming call of a circuit switched domain before informing the user equipment of performing the handover or when informing the user equipment of performing the handover; the user equipment will send a paging response message to a mobile switching center/visitor location register after handing over to the universal mobile telecommunications system or the global system for mobile communications if this handover is a handover due to an incoming call of the circuit switched domain.
