This paper proposes an integrated mobile IP and SIP handoff management architecture that exploits the complementary capabilities of mobile IP and SIP and thus extends the mobility functionality that is beyond either of them if applied solely. Furthermore, the integrated approach reduces the functionality redundancies that a simple hybrid approach tends to exhibit. The design of handoff polices for different scenarios are described. In particular, we expound our design philosophies with the example of macro terminal handoff management and perform an initial evaluation using three metrics: handoff delay, handoff reliability and handoff signalling load.
