  • Patent number: 6175622
    Abstract: A system and method for allowing a wireline or wireless carrier or service provider to transparently provide a virtual private network to wireless callers of the network. The method works in a telecommunications network including a service switch point, a service control point, and a first and second telephone. The method provides a virtual private network for the first and second telephone by performing a series of steps. First, an identifier for the first telephone is stored in a memory accessible by the service control point. Next, a first dialed number is received from the first telephone by the service switch point. The service switch point notifies the service control point to determine if the identifier for the first telephone is in the memory. If so, the service control point converts the number dialed by the first telephone to a second dialed number. The service control point then provides the second dialed number, being assigned to the second telephone, to the service switch point.
