ABSTRACT:
The virtual private network for cellular communications implements a secure local area voice and data network for use by members of an organization, such as a corporate customer. The virtual private network is implemented in the existing non-terrestrial cellular communications network in the form of software and routing tables that isolate the calls in the virtual private network from the existing cellular communications network infrastructure. This isolation can be effected, for example, by assigning fictitious station identifiers, such as telephone numbers, to the cellular subscriber stations served by the virtual private network. These fictitious numbers are identified by the gateway cellular switch that serves a customer's facility as subscribers served by the virtual private network.
