Abstract: 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.

Abstract: 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.

Abstract: 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.
