摘要： A method and system for performing handoff between a source system and a target system are provided. The target system has a different network access standard from that of the source system. An access terminal, connected to the source system, transmits a request message including an identifier of the access terminal to be identified in the target system, to the target system, via the source system, in order to access the target system. A session storage of the target system acquires the identifier of the access terminal from the access terminal via the source system. The session storage of the target system acquires session information of the access terminal from an old session storage to which the access terminal was connected before it accesses the source system, using the acquired identifier. After the session information is acquired, a gateway of the target system acquires context information related to a data service of the access terminal from a gateway of the source system. After handoff of the access terminal, the target system provides the data service to the access terminal using the session information and the data service-related information.

摘要： A handoff method between a source network to which a terminal is connected in order of a Base Station (BS) and an Access Service Network (ASN), and a target network to which the terminal is connected in order of a Packet Data Service Node (PDSN), a Packet Control Function (PCF) and an Access Network (AN). The terminal sends a handoff request message with AN information of the target network to the ASN via the BS. The ASN forwards the handoff request message to the PCF via the PDSN using the AN information. Upon receipt of the handoff request message, the PCF sends a request for session information to the ASN via the PDSN. The PDSN sends a request for context information to the ASN. Upon receipt of the session information request and the context information request, the ASN transfers the context information to the PDSN and transfers the session information to the AN via the PDSN and the PCF.

摘要： A method and system for supporting a handoff of an MS in a PMIP mobile communication system are provided. The method includes a target node transmitting a first registration request message to an HA in order to request registration of the MS, when the MS moves from the service area of a serving node to the service area of the target node; the serving node discarding a second registration request message without processing the second registration request message, when the serving node receives the second registration request message from the MS before the target node receives a first registration response message for the first registration request message from the HA; and the serving node requesting deregistration of the serving node to the HA, when the target node receives the first registration response message from the HA.

摘要： A system is provided for managing mobility of an Access Terminal (AT) in a Proxy Mobile Internet Protocol (PMIP) communication system. As the AT performs a handoff, a target Signaling Radio Network Controller (SRNC) delivers session information of the AT, acquired from a source SRNC of a source network, to a target Access Network (AN). An Authentication, Authorization and Accounting server (AAA) performs an AT access authentication process. Then, a target Access Gateway (AGW) performs a proxy registration procedure, with the target AN, and receives, from the AT, a message indicating a need to establish an interface with the HA. A Home Agent (HA) performs mobility management for the AT, receives a message for requesting proxy registration for mobility management for the AT, sends an access request message to the AAA, receives an access accept message, and sends a response message for proxy registration to the target AGW.
