Provided are a method for processing handover to provide IP mobility for mobile user equipment, a system thereof, and a Mobile IP (MIP) client device. 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.
Description
TECHNICAL FIELD[0001]Exemplary embodiments of the present invention relate to a method for processing handover to provide IP mobility for mobile user equipment, a system thereof, and a Mobile IP (MIP) client device; and, more particularly, to a method for processing handover in a heterogeneous mobility protocol mixed networkS, a system thereof, and a MIP client device, which are for providing mobility of mobile user equipment in a heterogeneous mobility protocol mixed networkS where a method for providing mobility for mobile user equipment is changed to a Client Mobile IP (CMIP) scheme or a Proxy Mobile IP (PMIP) scheme according to the network to be accessed.[0002]In an embodiment of the present invention, a client mobile Internet protocol (CMIP) and a proxy mobile Internet protocol (PMIP) will be described as an example of a heterogeneous mobility protocol. However, the present invention is not limited thereto. A method for processing handover between two different mobility protoc...
