<p>The embodiments of the present invention disclose a method, an apparatus, and a system for mobile Virtual Private Network (VPN) communication, and relates to the communications field. To solve the problem that network maintenance efficiency is low when IP traffic of a branch network served by a Mobile Subscriber (MS) is transmitted on a VPN, the technical solutions in the embodiments of the present invention includes: a mobile packet gateway obtains a network address of the terminal and a network address of a gateway virtual interface, where the network address of the gateway virtual interface and the network address of the terminal belong to a same network segment; creating a virtual interface for a Packet Data Protocol Context (PDP context) of the MS according to the network address of the gateway virtual interface; and obtaining a network segment address of a branch network served by the MS from the MS through the virtual interface according to a dynamic routing protocol. The technical solutions provided in the embodiments of the present invention may be applied in VPN communication.</p> |
