Abstract: A cellular or non cellular radiotelephone system consisting of a plurality of base station radios at one or more radio base station sites including method of connection of such base station radios to the Mobile Switching Center by the use of standard public telephone circuits whereby connections on these public telephone circuits are established only when required to provide communications to a mobile subscriber served by the radio base station.
Abstract: A method and system for identifying the location of mobile units within a cellular telephone system. A subset of cells is dynamically assigned to a mobile unit based upon the cell location of the mobile unit at the time of registration. The mobile unit records the subset information, and as long as the mobile unit remains in one of the cells in the subset, it does not re-register its location with the system. The system is able to locate the mobile unit within the assigned subset of cells. When the mobile unit enters a new cell that is not within the subset of cells, it re-registers with the system which then assigns a new subset of cells corresponding to its location within a new cell that did not belong to the previous subset.

Abstract: A cellular radiotelephone system including plurality of channels with a mechanism for dividing the channels into two diverse sets based on a division of the control channels used to transmit control information. The division is effected by providing that one group of subscriber sets begins scanning the control channels at the first control channel and only scans up to a maximum number of control channels, and a second group of subscriber sets begins scanning at another control channel not scanned by the first group.
