Abstract:
Method of channel allocation in a mobile communications network comprising at least base transceiver stations and mobile stations and wherein connections between the base transceiver station and mobile stations are set up over the radio path, in which network the method comprising:defining for each base transceiver station a predetermined safety area which comprises a set of cell areas of other base transceiver stations surrounding the base transceiver station in which introduction of channels for other connections between base transceiver stations in the safety area and mobile stations within their cell areas could cause mutual interference between previous connections of the base transceiver station and the other connections,measuring channel interference levels,averaging the measurements of the channel interference levels,allocating a channel K for usage as a first connection between a mobile station and a base transceiver station based on the channel interference levels,introducing said channel K, and after introduction of channel Ktemporarily limiting introduction of channels for the other connections between base transceiver stations in the safety area and mobile stations in the safety area, if introduction of the other channel would cause mutual interference between the first connection and the other connections.
