Dynamic channel management scheme to increase performance index of cellular networks

A dynamic channel management scheme (DCMS), using both a one-layer cellular architecture (OLCA) and a two-layer cellular architecture (TLCA), for use in areas with random offered traffic load, is presented. The philosophy of DCMS is based either on OLCA or TLCA, and is proposed for optimisation of the handoff blocking probability performance of highspeed moving terminals and the call blocking probability of the rest of the calls in a congested urban area, with random offered traffic load. Also, the number of channels assigned to microcells and the umbrella cell, is regulated dynamically achieve to the foregoing objectives.
