<p>A channel allocation process for a cellular telephone network (99) starts from a position of homogeneity (phase 100) in which each base station has the potential to use all channels, and develops ever greater heterogeneities by processing a combination of short and medium range interactions between the base stations themselves (phase 200), causing each base station of the cellular telephone network to inhibit its neighbours from using a given channel, to generate (step 203) a usage factor for each channel in each cell indicative of the level of interference to be expected on that channel in that cell. Channels can then be allocated to each base station according to the ranking of the usage factors determined for the channels at that base station (phase 300). The entire network may be emulated by a single processing means, controlling the base stations of the network (99) in accordance with the results of the process. Alternatively, each base station of the network (99) performs that part of the process relating to itself, in cooperation with its neighbours, and utilises channels in accordance with the results.</p> |
