Abstract
A mobile node in communication with a first wireless system detects a handoff condition and responsively transmits a handoff request to a handoff controller. In response to the handoff request, the handoff controller selects a second wireless system for the mobile node and establishes a packet registration with the second wireless system on behalf of the mobile node. When the registration process is completed, the handoff controller transmits a handoff instruction to the mobile node. The mobile node may then acquire a radio link with the second wireless system and use the packet registration established by the handoff controller to send and/or receive packets via the second wireless system.
