Abstract
A telecommunications system and method is disclosed for assigning channels based upon interference and channel quality measurements. The interference level measurements are carried out on the uplink of the cellular network. Channels are categorized in accordance with interference bands depending upon the interference levels. Incoming service is pre-assigned to a channel in the highest available interference band and a channel quality measurement (CQM) is conducted. The service is either continued (assigned) on the same channel, reassigned to a channel with lower interference or dropped if no other channel with lower interference is available based upon the channel quality measurement and the interference bands having available channels.
