<p>A cellular telecommunications method for use in a cellular telecommunications network having at least one cluster of adjoining cells, including allocating a respective control channel frequency to each cell for transmitting a control channel in a cell, allocating a set of frequencies to the cluster for use by the cells, with each cell having a respective subset of said set, and swapping between the frequencies of a subset for first traffic channels of a cell (34) and swapping between the sets of frequencies in a cluster for second traffic channels of the cell (32). The control channel frequency is allocated to third traffic channels of the cell (30). Calls are selectively allocated to one of the traffic channels based on transmission characteristics of the call. The quality of service provided by the second channels is greater than that of the first channels which again is greater than that of the quality of service provided by the third channels. A cellular network, in particular a GSM network, has base stations which are adapted to provide the first, second and third traffic channels by executing intracell slow frequency hopping and intercell frequency allocation swapping.</p> |
