摘要： A method and apparatus for performing a detach procedure between a first device and a second device. The method includes receiving, at a first device, an informational exchange message to delete an IP security association between the first device and a second device. The informational exchange message further includes a notify message indicating that the deletion of the IP security association is due to a detach request. In response to the notify message indicating that the deletion of the IP security association is due to the detach request, the method further includes automatically deleting, at the first device, a mobility related state associated with the host-based mobility protocol.

摘要： A method and apparatus for performing a handover of a communication session from a non-3GPP access network to a 3GPP access network in which only a Gn/Gp-based Serving GPRS Support Node has been deployed in the 3GPP access network. The method includes establishing the communication session between a user equipment and an Evolved Packet Core through the non-3GPP access network, and performing a handover of the communication session from the non-3GPP access network to the 3GPP access network. Performing the handover includes providing information to the UE of a selected packet data network gateway prior to performing the handover, and providing the information of the selected packet data network gateway from the user equipment to the 3GPP access network during the handover to maintain continuity of the communication session between the user equipment and the Evolved Packet Core.

摘要： A media access gateway comprises a wireless network interface, an address assignment module, and a proxy mobility agent module. The wireless network interface establishes a wireless link with a wireless terminal. The address assignment module receives an address request message, which includes a mobility signal from the wireless terminal. The proxy mobility agent module selectively transmits a proxy binding update to a local mobility anchor and receives a proxy binding acknowledgement from the local mobility anchor. The address assignment module selectively transmits an address assignment message to the wireless terminal when the mobility signal indicates proxy mobility. The address assignment message is based on address information in the proxy binding acknowledgement.

摘要： A network control module includes an access module that determines whether a first packet data network gateway communicating with a first packet data network also communicates with a second packet data network. The network control module also includes a selection control module in communication with a mobile wireless terminal. The mobile wireless terminal attempts to access the second packet data network by establishing a connection with a second packet data network gateway that communicates with the second packet data network. In response to the access module determining that the first packet data network gateway also communicates with the second packet data network, the selection control module commands the mobile wireless terminal to access the second packet data network through the first packet data network gateway.
