<p>In a network for serving cordless stations located in microcells, speech channels are divided into channel groups such that no intermodulation products occur among the channels of each group. Base units are located respectively in the microcell sites to establish two-way speech channels with their cordless stations. Each base unit generates and updates priority values of the channel groups as representations of usages of all channels through a statistical process. Depending on the updated priority values different channel groups are uniquely assigned to the base units. Timeslots are defined uniquely by the respective base units using the identifiers of the assigned channel groups for broadcasting zone-registration polling signals during the defined timeslots to elicit a zone registration response from each cordless station. <IMAGE> <IMAGE></p> |
