Abstract:
A method for processing handover to provide IP mobility for mobile user equipment, a system thereof, and a Mobile IP (MIP) client device using the same method. The method processing handover at a home agent in a heterogeneous protocol mixed network includes: at a home agent, creating a Proxy Mobile IP (PMIP) tunnel when user equipment accesses a PMIP network; at the home agent, creating a Client Mobile IP (CMIP) tunnel when a CMIP network is accessed due to handover of the user equipment; and at the home agent, severing the PMIP tunnel when the user equipment completes performing handover.
