Abstract: PROBLEM TO BE SOLVED: To perform dynamic allocation and to obtain the growth of a simple system and a high capacity by allocating channels according to a priority that is set to a channel list as a function of long-term and short-term interference fluctuation in every cell/sector in a wireless communication network. SOLUTION: A telephone exchange center 10 which controls entire operations of a system has a dynamic channel allocating system IBDCA on an interference base and performs signal measurement, channel sequencing, call allowance, channel allocation, call maintenance, hand-off, etc. A base station 14 sequences an entire spectrum by signal intensity RSS to long-term fluctuation based on the result that the intensity RSS of a mobile communication device 20 and a carrier-to-interference ratio are measured, and further sequences several channels of the highest order based on the RSS of short-term fluctuation. Then, it allocates a channel that is sequenced based on a prescribed reference in response to a call. Thereby, a channel can dynamically and automatically be allocated to a mobile station.

Abstract: An interference based dynamic channel assignment scheme for a wireless communication network, for self configuring dynamic channel assignment of a plurality of channels, comprises the steps of: prioritizing a channel list and prioritizing a selected subset of the prioritized channel list. In further enhancements of the present invention, prioritizing a channel list is distributed on a per cell/sector basis so that prioritization is independent of frequency usage information from other cells/sectors and prioritization is based upon uplink and downlink characteristics.
