Admission Policy in Wireless Systems with Overlapping Coverage

  • Xavier Lagrange

In a typical cellular network, one finds a considerable portion of the service areas are served by multiple base stations. The so called overlapping cells provide opportunities to improve the traffic handling capacity or quality of service of the network. However, the limited overlapping coverage results in different quality of service to different subsets of mobile terminals and hence causes unfairness. We propose a simple admission policy that equalizes the quality of service across the system. Furthermore, through this policy and the reduction in the variance of the quality of service, we gain considerable improvements in traffic handling capacity and probability of forced termination of calls in progress. We develop a model based on a Markov Modulated Poisson process and quantify the benefits from this policy.
