Enhancing Terminal Coverage and Fault Recovery in Configurable Cellular Networks Using Geolocation Services
Mostafa A. Bassiouni, Wei Cui · Kluwer Academic Publishers eBooks · 2005
In this paper, we discuss the application of geolocation services in improving mobile connectivity and enhancing the effectiveness of fault recovery in configurable cellular networks. Real-time location measurements (e.g., GPS) are used to guide the movement of the mobile base stations to provide better coverage of the different groups (swarms) of mobile terminals. Umbrella coverage via a more powerful transceiver is used to enhance the overall terminal coverage and simplify the movement coordination strategies and improve the efficiency of the channel allocation protocol. When a base station becomes immobilized or faulty, a recovery protocol is used to prevent discontinuation of coverage for the mobile terminals that were being serviced by this base station. Real-time location measurements are crucially important for the proper execution of the recovery protocol.
