摘要： A method for mobility management for a mobile node that establishes a connection with a first network while in a second network and traverses to a third network includes transferring location management information from the second network to the first network. An indirection path from the first network to the third network is established for data packets directed to the mobile node. The data packets directed to the mobile node are transferred using the indirection path without traversing the second network. This allows for the address anchor of the connection to remain at the second network while providing a flow anchor at the first network, which allows a direct flow to the third network.

摘要： An apparatus is configured to perform a method for optimized route mobility. The method includes determining that a mobile node moves from a first network to a second network. The method also includes, in response to determining the movement of the mobile node, receiving, at an access/gateway router of the second network, a prefix delegation message from a router of the first network, the prefix delegation message configured for movement of an IP prefix associated with a communication session of the mobile node from the first network to the second network, the prefix delegation message comprising the IP prefix previously allocated to the first network. The method further includes updating a routing table to reflect the moved IP prefix.

摘要： Embodiments of the present invention provide a routing method between base stations, a serving gateway, and a base station, where the method includes: receiving, by a first serving gateway, a first user data packet of first UE sent by a first base station, and determining, according to the first user data packet, whether the first serving gateway serves both the first UE and second UE, where the second UE is a communication peer end of the first UE; and if the first serving gateway determines that the first serving gateway serves both the first UE and the second UE, triggering, by the first serving gateway, the first base station to acquire first routing information required for direct communication with a second base station, and triggering the second base station to acquire second routing information required for direct communication with the first base station, so that the first base station and the second base station establish a direct connection according to the first routing information and the second routing information. According to the method provided in the embodiments, a route between the two base stations is more optimal, and a transmission delay of a data packet is also reduced.

摘要： An embodiment method for session handling for a connection between an UE and a network includes establishing, at a first distributed EPC, user and IP sessions over the connection through the first distributed EPC. The first distributed EPC includes a first PGW at which the IP session is anchored. The method also includes holding original IP resources and releasing original connection resources for the sessions at the first distributed EPC when the UE moves beyond the first distributed EPC to a second distributed EPC. The method then establishes a tunnel between the first PGW and a second PGW for the second distributed EPC. The tunnel utilizes the original IP resources and new connection resources at the second distributed EPC. The method then routes data from the tunnel, through the first PGW, and to the network.

摘要： An apparatus is configured to perform a method for mobility management. The method includes establishing a first Packet Data Network (PDN) connection between a user equipment (UE) and a first Packet Data Network Gateway (PGW) associated with a first group of Serving Gateways (SGW) within a first geographical area; establishing communication with a handover destination SGW associated with a second PGW, the second PGW associated with a second group of SGWs within a second geographical area; and upon a determination that the UE moves from the first geographical area to the second geographical area, establishing a General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel connection between the first PGW and the handover destination SGW, and updating the first PDN connection to use the GTP tunnel connection between the first PGW and the handover destination SGW.
