Abstract
Abstract An improved cellular mobile radio telephone system is described wherein the switching matrices used to provide communication paths between subscribers is also used to provide paths for carrying control information between a network control and the various transceivers, receivers and transmitters at cell sites. Additionally, statistical multiplexers are provided at the cell sites for multiplexing control signals for many transceivers, receivers and transmitters onto the transmission facilities connecting the cell site with the network control system. At the network control system, apparatus is provided to reformat and packetize control signals from many statistical multiplexers and present the reformatted, packetized information to a network control processor.

Claim 1
Independent Claim
319 words
A cellular mobile radio service system, comprising: a plurality of cell sites each comprising a plurality of transceivers each transceiver having a first control port and being responsive to control signals at said first control port; a network control system coupled to each of said plurality of cell sites and to the telephone network for controlling said plurality of transceivers and for establishing telephone connections between said telephone network and said plurality of transceivers; and a plurality of first transmission facilities each coupled between said network control system and one of said cell sites; each of said cell sites further comprising a first statistical multiplexer having a plurality of lower data rate ports and a higher data rate port, each of said plurality of transceivers having its first control port coupled to one of said plurality of lower data rate ports, said higher data rate port being coupled to one of said plurality of first transmission facilities each of said plurality of transceivers having an audio signal port, coupled to one of said plurality of first transmission facilities; said network control system comprising: a switching matrix having a first plurality of terminals coupled to said telephone network, a second plurality of terminals coupled to said plurality of first transmission facilities, and a third plurality of terminals; a processor for controlling the selection of paths through said switching matrix to establish telephone connections between said plurality of transceivers and said telephone network, and for exchanging control signals with said plurality of transceivers; a control concentrator having a first plurality of ports coupled to said third plurality of terminals and a port coupled to said processor; said processor controlling the establishment of second paths through said switching network between said control concentrator and a plurality of said first statistical multiplexers, each of said second paths coupling one of said plurality of statistical multiplexers to one of said third plurality of terminals.
Claim 2
Dependent Claim
319 words
A cellular mobile radio service system, comprising: a plurality of cell sites each comprising a plurality of transceivers each transceiver having a first control port and being responsive to control signals at said first control port; a network control system coupled to each of said plurality of cell sites and to the telephone network for controlling said plurality of transceivers and for establishing telephone connections between said telephone network and said plurality of transceivers; and a plurality of first transmission facilities each coupled between said network control system and one of said cell sites; each of said cell sites further comprising a first statistical multiplexer having a plurality of lower data rate ports and a higher data rate port, each of said plurality of transceivers having its first control port coupled to one of said plurality of lower data rate ports, said higher data rate port being coupled to one of said plurality of first transmission facilities each of said plurality of transceivers having an audio signal port, coupled to one of said plurality of first transmission facilities; said network control system comprising: a switching matrix having a first plurality of terminals coupled to said telephone network, a second plurality of terminals coupled to said plurality of first transmission facilities, and a third plurality of terminals; a processor for controlling the selection of paths through said switching matrix to establish telephone connections between said plurality of transceivers and said telephone network, and for exchanging control signals with said plurality of transceivers; a control concentrator having a first plurality of ports coupled to said third plurality of terminals and a port coupled to said processor; said processor controlling the establishment of second paths through said switching network between said control concentrator and a plurality of said first statistical multiplexers, each of said second paths coupling one of said plurality of statistical multiplexers to one of said third plurality of terminals.
Claim 3
Dependent Claim
180 words
A cellular mobile radio service system in accordance with claim 1, wherein each of said cell sites further comprises: a second statistical multiplexer having a plurality of lower data rate ports and a higher data rate port and wherein each of said plurality of transceivers has a second control port, said transceiver being responsive to control signals at said first or said second port; each of said plurality of transceivers having its second control port coupled to one of said plurality of lower data rate ports of said second statistical multiplexer; said system comprising a plurality of second transmission facilities each coupled between said network control system and one of said cell sites; said switching matrix comprising a fourth plurality of terminals, coupled to said plurality of second transmission facilities; each of said second statistical multiplexer higher data rate port being coupled to one of said plurality of second transmission facilities; said processor being operable to control the establishment of said second paths through said switching network between said control concentrator and said pluralities of said first and second multiplexers.
