Wireless communications system and method having dynamic reallocation of communication frequencies
First Claim
1. In a telephone system in which plural base stations communicate with plural remote units using RF links and in which said base stations provide telephone coverage over a predetermined geographic area, said base stations comprising RF communication means for communicating with said remote units over a predetermined set of RF frequencies, the communications between said base stations and said remote units on the set of predetermined RF frequencies utilizes a time series of repeating frames, each frame comprising plural slots and each slot at a particular base station may be communicated using a different frequency from the other slots within a frame, a method of communicating comprising the steps of:
- (a) monitoring at each base station within the telephone system each of the predetermined set of RF frequencies to determine which frequencies are in use by remote units of the same telephone system within the communications range of said base station, each of said base stations determining available slot/frequency combinations within the predetermined set of RF frequencies;
(b) using one of the frequencies determined not to be in use when a need to establish a new communication with one of said remote units within the same telephone system is requested by said remote unit.

Abstract
In a wireless communication system in which plural base stations communicate with plural mobile stations using a control slot and plural voice (or data) slots, the present invention dynamically allocates which of a predetermined set of frequencies are used by a given base station at a given time. The base stations monitor the predetermined set of frequencies to determine which frequencies are being used within which slots within the range of radio reception of the base station. Currently unused frequency/slot combinations are assigned by a base station to service the next request for a voice slot.
