Dynamic base station selection for personal communication systems with distributed control schemes

Distributed control schemes allow base stations to be placed at locations corresponding to high expected traffic. This flexible base station placement creates overlapping segments-a property which can be utilized to improve the system's performance. A new dynamic base station selection technique for overlapping cell placement is considered. This base station selection scheme in overlapping areas affects the system's performance. The technique realizes robust traffic performance for personal communication systems in fluctuating and heavily tapered traffic. A mathematical analysis method based on a state transition model is used to evaluate a system which employs the proposed technique. The results indicate that the proposed technique improves blocking probability and carried traffic performance.
