Abstract
Method and apparatus for effecting handoff in a system supporting both wireless and packet data service communications. In one embodiment, the serving network provides information to the target network sufficient to establish the Point-to-Point Protocol (PPP) connections for handoff. In an alternate embodiment, the serving network and the target network do not share capabilities with respect to concurrent multiple service instances. When the serving network knows the status of the target network, the serving network takes responsibility for the handoff.
