Method, Apparatus, and System for Mobile Virtual Private Network Communication

摘要

A mobile packet gateway obtains a network address of the terminal and a network address of a gateway virtual interface. The network address of the gateway virtual interface and the network address of the terminal belong to a same network segment. A virtual interface is created for a Packet Data Protocol Context (PDP context) of the MS according to the network address of the gateway virtual interface. A network segment address of a branch network served by the MS is obtained from the MS through the virtual interface according to a dynamic routing protocol.
