Abstract
A system and method of facilitating handoff of communications with a mobile terminal between a first wireless access network and a second wireless access network having different air interfaces. The system and method including pre-registering the mobile terminal in the second access network prior to handoff, while the mobile terminal is conducting a communication session using the first access network. Upon a determination that a handoff is needed, communication is transparently tunneled to the secondary access network through the primary access network. During tunneling, the air link of the first wireless access network is employed to communicate with the secondary access network to facilitate the handoff.
