  • Method of upgrading a cellular network
    Patent number: 5251249
    Abstract: A method of enhancing an existing cellular network is described such that a new system can operate in tandem with an existing cellular network without disrupting service to existing subscribers and without requiring the replacement of existing equipment. In particular, this is achieved by giving control of all dedicated control channels (CCHs) in each cell to a second switch. The second switch thereby is provided with the control of call set-ups, thus providing for more than one category of mobile subscriber. Some subscribers can be serviced by the existing switch and others by the second switch.
