Optimal system capacity in handover prioritised schemes in cellular mobile telecommunication systems

This paper investigates the issue of capacity maximisation in the presence of new call and handover requests in cellular mobile telecommunication systems. Initially, both non-prioritised and prioritised handover schemes are analysed leading to the identification of the optimal configuration (e.g. number of reserved channels, queue length) in order to maximise the system capacity. The 'guard channels' prioritised scheme is analysed in the sequel and it is proved that it does not maximise the system capacity, however, it approximates the optimal configuration. Finally, a new handover prioritised scheme, which achieves the maximum system capacity, is proposed and analysed. This scheme is based on a new resource management scheme: the 'unequally shared channels', which are allocated it, new calls and handovers with a different priority determined by a single control parameter.
