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.
