Communication system providing mobility management internetworking between a C-interface radio system and an overlay mobile radio network

Image Number 5 for United States Patent #5629974.

A communication system providing mobility management interworking between a C-interface radio system and an overlay mobile radio network. In the first embodiment the radio system uses NCAS signalling and communicates with the SCP using the MMAP protocol. The SCP then makes the conversion to traditional MAP protocol when necessary to communicate with other network entities. The SCP takes care of the interworking between these transactions. In the second embodiment the SCP only relays the MAP operations embedded into TCAP messages transparently between the radio system RS and the overlay network element when the communication takes place between the RS and the overlay network. Thus the transaction is between the RS and the overlay network element. A Relay Protocol is needed between the RS and the SCP to carry the appropriate address information and to discriminate between the transparent MAP operations and non-transparent MMAP operations.
