Abstract
A telecommunications system and method for allowing calls to and from mobile terminals to be handled directly by a remote terminal without the need for trunk lines between the remote terminal and the network. This is accomplished by tunneling the signaling messages between the remote terminal (RT) and the network (Mobile Services Center/Visitor Location Register), for example, via the Transfer Communication Protocol/Internet Protocol (TCP/IP), which is a communications link of the type used by the Internet. The remote terminal preferably consists of a traffic channel controller for allocation and release of traffic channels over the satellite, an interworking function for speech coding and for signaling via, for example, the TCP/IP, and the Public Switched Telephone Network (PSTN) interface. These main three components function together to provide cost-effective cellular coverage to remote villages.
