Abstract

The authors address the problem of increasing the utilization of scarce radio spectrum by sharing a common pool of land mobile radio channels between mobile telephone and mobile dispatch services, which are assumed to have Erlang-B and Erlang-C service models, respectively. Due to differences in their traffic characteristics and quality of service requirements, direct sharing proves to be infeasible. To harmonize these differences, a new technique called the reserve margin algorithm is introduced. Simulation results show that the new strategy is effective in trading between the mobile telephone blocking probability and the mobile dispatch cell setup delay, and is more efficient than a previously considered strategy. Although the authors consider specifically the application of the new resource sharing strategy in mobile communication networks, the strategy is generally applicable in an queueing systems combining the blocked-calls-queued and blocked-calls-dropped services
