LOCATION REGISTRATION METHOD FOR A MOBILE NODE

摘要

A location registration of a mobile terminal which controls 3 layer location registration and portability by using 2 layer identifier information of a multimode mobile terminal supporting the heterogeneous access network mobility is provided to perform 3 layer location registration through various access network. A mobile node(MN)(208) accesses 2 layer to a PoA(Point of attachment)(205) which performs handover(S11). The wireless access point transmits 2 layer identifier information of the mobile terminal to an access router(202). The access router requests the location registration of the mobile terminal corresponding to 2 layer identifier information to the portability control server(201) controlling the movement of the mobile terminal the administration(S17). The access router transmits the network binding information transmitted to the response about request to the mobile terminal(S19). According to the transmitted network binding information, the mobile terminal completes the location registration.
