Mathematical Model of Operation of a Cell of a Mobile Communication Network With Adaptive Modulation Schemes and Handover of Mobile Users

A model of a cell communication network, divided into zones, with the dependence users' service time on zone, in which they are located, is considered. The arrival flow users defined by marked Markovian process. number that can receive simultaneously finite. If reached limit, then new lost, except come to already during (handover users). For short-term storage such users, there buffer finite capacity. Cell operation modeled multi-server queueing system. behavior this system described multi-dimensional Markov chain. algorithms for calculating stationary distribution chain and main characteristics quality have been developed.
