Traffic statistics in a self-organizing cellular telephone system

A novel family of techniques for assigning channels to calls in a cellular mobile telephone system based on real-time measurements of signal strength is introduced. A discussion of the behavior of the system using self-organizing techniques is presented. Results are presented for traffic distribution per channel, traffic distribution per cell site, mean time between handoffs, and mean signal-to-interference ratio. In each case, it is shown that the system behavior is progressive and degrades gracefully with increasing traffic; there is, for example, no threshold behavior in signal-to-interference ratio. This suggests that the concept can be introduced in stages as the traffic demand increases, without abrupt changes in system behavior
