Title: Signal transfer system for linking mobile communications networks
Inventor: MORAN TIMOTHY LEO
IPC: H04W36/14
Filed: 1998-10-05
Abstract: The system uses a circuit allocation method ensuring communication between different radio systems. The process for establishing signal transfer between a first mobile radio communication system, and a second radio communication system includes use of a terrestrial line switching element.  The method includes a number of stages, the first of which comprises establishing a number of circuit links between the base station and the first mobile station, with the base station being connected to the processing platform.  The second stage is detection by the first radio system of the need to transfer a signal. The third stage comprises channelling the message through the data platform prior to the fourth stage of selection of circuit links. This is followed by  allocation of a mobile communication network by the second system on the basis of the message, and finally transfer of the signal to the mobile communication resource via the selected circuit.
