Abstract

A method and system for servicing a mobile node by a proxy when it joins a foreign network is disclosed. When the mobile node connects to a first point-of-attachment in the foreign network, the foreign network detects the existence of this mobile node. Then, a first mobile node proxy is established that is in communication with the foreign network. The proxy acquires the home network based IP address associated with the mobile node and IP addresss associated with a mobile agent servicing the mobile node through the proxy pretending that the proxy is the mobile node. On behalf of the mobile node, the proxy establishes a communication route between the mobile node proxy to the home network through the foreign network using the acquired IP addresses. As such, the proxy shields the mobile node from conducting at least one control signaling process when the mobile node joins the foreign network so as to eliminate the need for the mobile node to be cognizant of the control signaling process, thereby further eliminating the need for the mobile node to consume resources for participating in the control signaling process.
