Abstract
A method and apparatus of handoff decision making for heterogeneous network environments are described. In one embodiment, the method includes receiving session initiation protocol (SIP) messages from a mobile device via a wireless local area network (WLAN). The SIP messages contain data identifying at least one current network characteristic. The method further includes determining whether a handoff trigger for the mobile device is detected using the current network characteristic.
