20100115110 | REALIZING METHOD OF EMERGENCY CALL REGISTRATION - A realizing method of emergency registration is disclosed. When the user equipment in the visited network initiates an emergency registration request, the method comprises the following steps: after P-CSCF of the visited network receives the emergency registration request sent from the user equipment, it forwards the message to S-CSCF of the home network. The S-CSCF sets the emergency registration expiration time according to the setting policy for emergency registration expiration time, includes it into the emergency registration response sent to the P-CSCF which retrieves the emergency registration expiration time from the emergency registration response and sends the message to the user equipment, which in turn retrieves the emergency registration expiration time from the emergency registration response. The factors of the setting policy for the emergency registration expiration time comprise: a type of the emergency call, the location information of the visited network and the location information of the user equipment. | 05-06-2010 |
20100185772 | METHOD FOR IMPLEMENTING SERVICE INTERACTION IN THE IP MULTIMEDIA SUBSYSTEM - A method for implementing service interaction in the IP multimedia subsystem is disclosed in the present invention, wherein each service logic has a unique service identifier. The method comprises the following steps: (a) a Serving-Call Session Control Function (S-CSCF) sends a session initiation protocol (SIP) request message to the service capability interaction manager (SCIM) or to the application server (AS) to which a user requests for a service; (b) after the AS or SCIM has received the request and has executed this service, it inserts the service identifier of this service into the SIP request, and returns the SIP request with the service identifier to said S-CSCF. With the present invention, most of the service interaction requirements can be satisfied. | 07-22-2010 |
20100189246 | METHOD FOR REALIZING USER DECISION USER BUSY FORWARDING - The present invention provides a method for implementing call forwarding on user-determined user busy, comprising the following steps of: step 1: after receiving a session request routed by a CSCF from a calling side ( | 07-29-2010 |
20100296418 | METHOD FOR IMPLEMENTING CENTRALIZED SERVICE CHAIRMAN SIDE CONFERENCE SERVICE OF IP MULTIMEDIA SUBSYSTEM - 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. | 11-25-2010 |
20120213221 | METHOD OF ESTABLISHING OPTIMIZED MEDIA PATH AND SIGNALING GATEWAY FOR IMPLEMENTING THIS METHOD - Provided are a method and signaling gateway for establishing an optimized media path applied in an IMS network. The method includes: during the process of forwarding a session description protocol (SDP) request and response, when receiving a SDP response of a first session, a first ALG judging that there is an optimized media path between itself and a second ALG, then when sending the SDP response of the first session, including indication information in the send SDP response; the first ALG sending a SDP request with the target being the second ALG; and after having received the SDP response of the first session including the indication information or after having received the SDP request with the target being the second ALG and the SDP response of the first session including the indication information, the second ALG sending the SDP response of the first session. | 08-23-2012 |
20120220300 | METHOD AND SYSTEM FOR REALIZING SESSION HANDOVER - 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. | 08-30-2012 |
20120278379 | Relay Node, Distributed Network of Relay Node and Networking Method Thereof - A relay node, a distributed network of a relay node and a networking method thereof are provided by the present invention, which can manage and select the relay node efficiently. The networking method of the distributed network of the relay node includes: a relay node joining in a distributed peer-to-peer network with its own home domain information being carried, and constructing a local route table; the relay node, according to a pre-obtained neighbor home domain information of a present node, searching the local route table of the present node or searching the local route table of the present node and the local route table of other relay node for the relay node in a neighbor home domain, and constructing a candidate relay node list of the neighbor home domain. | 11-01-2012 |
