Document Type and Number:
Japanese Patent JP2013232926
Kind Code:
A
Abstract:
To provide a method and apparatus for effecting handoff in a system supporting both wireless and packet data service communications.
A serving network provides a target network with information sufficient to establish 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.
