Method and apparatus for handoff of a wireless packet data services connection

Claims an end of the movable to seat (MS) and novel method for using different type air interface wireless access network and device for seamless handover. The embodiment of fabricating enabled MS in different RAN the handover, wherein it is that the routing polysemy, and which is a magnetism losses of network data. The sealing of the first air third first RAN cover area is used to the second air interface and RAN cover area, MS determining whether the routing polysemy to generate from the form of RAN, and according to the charging trigger wherein network address the register of a. External mechanism (FA) monitoring network address in packet data service node (PDSN), founds for same MS register. To the decision, PSDN terminates from MS the mobile between different RAN a redundancy R-P network connection with.
