A media access gateway includes a wireless network interface, an address assignment module, a proxy mobility agent module, and a profile module. The wireless network interface establishes a link with a wireless terminal. The address assignment module receives an address request message, including 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. The address assignment module transmits an address assignment message to the wireless terminal in response to the mobility signal indicating support or preference for proxy mobility. The address assignment message is based on address information in the proxy binding acknowledgement. The profile module retrieves a profile for the wireless terminal from a server. The address assignment module selectively transmits a second address assignment message to the wireless terminal based on the address information in the profile.
