Patent ID: 8599790

Claim:
A media access gateway comprising: a wireless network interface configured to establish a wireless link with a wireless terminal; a tunneling module configured to establish (i) a first tunnel with a first local mobility anchor associated with a first packet data network, and (ii) a second tunnel with a second local mobility anchor associated with a second packet data network; a proxy mobility agent module configured to store a mapping of assigned addresses to local mobility anchor identifiers, wherein the mapping includes an entry that maps a first assigned address to a local mobility anchor identifier of the first local mobility anchor, and upon receiving a packet from the wireless terminal, the proxy mobility agent is configured to select one of the first local mobility anchor and the second local mobility anchor in response to (i) a source address of the wireless terminal and (ii) the mapping, and the tunneling module is configured to tunnel the packet to the selected one of the first local mobility anchor and the second local mobility anchor; and an address assignment module configured to transmit an address assignment message to the wireless terminal, wherein the address assignment message includes the first assigned address and a prefix usage indicator, the first assigned address comprises a network-based mobility address in response to the prefix usage indicator having a first state, the first assigned address comprises a client-based mobility address in response to the prefix usage indicator having a second state, and the tunneling module, the proxy mobility agent module, and the address assignment module are implemented by one or more processors executing programs from one or more memories.
