  • Method and system for handoff of mobile node in mobile communication system supporting proxy mobile internet protocol
    Patent number: 8224327
    Abstract: Disclosed is a way to solve a problem of an operation error, which may occur in transmitting a Binding Update (BU) or Registration ReQuest (RRQ) message for a mobile node to a home agent due to the fact that a PDSN supports a Proxy Mobile Internet Protocol (PMIP) for the mobile terminal and the corresponding mobile node supports a client mobile IP when there is the mobile node using the client mobile IP in a 3GPP2 mobile communication system supporting the PMIP, thereby enabling efficient communication.

  • Handoff method between heterogeneous networks and system thereof
    Patent number: 8036175
    Abstract: 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.

  • HANDOFF METHOD BETWEEN HETEROGENEOUS NETWORKS AND SYSTEM THEREOF
    Publication number: 20080170548
    Abstract: 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.
