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.
