METHOD FOR DYNAMIC CHANNEL ALLOCATION WITH REARRANGEMENT IN A TDD/CDMA RADIO COMMUNICATIONS SYSTEM AND SYSTEM THEREFOR

摘要

Method for distributing radio channels in a radiocommunications system in which a fixed unit (11-j) allocates radio channels to a plurality of remote units (12-1 to 12-m), and in which the radio channels are defined by a time slot of a frame and a pseudo-random sequence. Processor means carry out an analysis of the quality requirements in relation with an incoming, or in process, or foreseen incoming call, and of a list of occupied channels prepared by the fixed unit (11-j), with the object of releasing, by means of a handover procedure, a busy channel on the list and belonging to a time slot having the quality closest to that required for the call to which it is desired to allocate a channel. The fixed unit (11-j) allocates to said call the time slot that includes the released radio channel.
