Protocol for local routing of incoming calls from the public switched telephone network to a cellular network

摘要

The method involves initialising local authentication by identifying the location of a transceiver which is used for access. Service subscriber digital words, personal communications signals, identification numbers and a confidential code are then sent to a management control centre. A selection number is then allocated, a direct path provided and service access authentication performed. The call is then connected and an interrogating signal is transmitted to the control services. A call message containing an ID number is then transmitted which establishes the aerials to be used and establishes the path.
