Cordless telecommunication network with dynamically assigned unique timeslots for zone registration polling
First Claim
1. A telecommunication network for serving cordless units located in a plurality of service zones, said network having radio speech channels which are organized into a plurality of channel groups such that no intermodulation products occur among the channels of each group, said network comprising a plurality of base units located respectively in said service zones, each of said base units comprising:
- means for establishing two-way speech channels with those of the cordless units which are located in the same zone as the base units;
means for generating priority values of said channel groups as representations of usages of said groups through a statistical process and uniquely assigning one of said channel groups to the base units according to said priority values; and
means for defining a timeslot depending on the assigned channel group and transmitting a polling signal from the base units during the defined timeslot to elicit a response from the cordless units located in the same zone as the base units.

Abstract
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.
