Patent ID: 6970459

Claim:
A communication network system capable of providing communication via an internetwork, the communication network system comprising (a) a tunnel server which provides for a tunneling service via an internetwork, and has a global address for identifying a first end point of a tunnel provided by the tunneling service; (b) a mobile wireless system for communicating via a wireless link, and having a mobile virtual tunneling protocol client which has access to the global address for the first end point so as to enable communication with the tunnel server, the mobile wireless system being capable of being transported to a location remote from the first end point; and (c) a tunnel agent subsystem for communication via the wireless link with the mobile virtual tunneling protocol client of the mobile wireless system and for communication via an internetwork with the mobile virtual tunneling protocol server for establishing a mobile virtual tunneling protocol tunnel between the mobile virtual tunneling protocol client of the mobile wireless system located at a second end point remote from the first end point and the mobile virtual tunneling protocol server at the first end point, the tunnel agent subsystem assigning to the mobile wireless system a local end point identification for identifying the second end point of the mobile virtual tunneling protocol tunnel.
