ABSTRACT:
A proxy is utilized to limit the RF bandwidth needed for foreign IP registration. An existing RF log-in procedure causes the proxy to initiate and complete the foreign IP registration procedure with the foreign agent at the RF site where the mobile node is located. The proxy then acts as a locally connected (i.e., direct ethernet connected) device for each IP address for which it is proxying, and thus there is no need to use RF to register a mobile with the active foreign agent. This allows the use of off-the-shelf home and foreign agents to complete the mobile IP architecture, and reduces the RF bandwidth used, since the RF portion of the registration process (the registration between the active foreign agent and the mobile) is reduced.
