Admission Control and Channel Mapping Strategies for GEO Satellite Multicast/Broadcast Systems

One central problem in the network planning and optimisation of W-CDMA GEO Satellite networks is the efficient use of the limited satellite resources such as power, capacity and bandwidth, task that is under the responsibility of Radio Resource Management. Services offered by a W-CDMA satellite network can be classified as conversational, streaming, interactive and background. In this paper we present an Admission Control (AC) strategy for unidirectional (downlink) satellite systems delivering multicast and broadcast services to mobile users. The results from the simulation study that demonstrate its performance are presented and conclusions derived. Key-Words: Admission Control, RRM, GEO satellites, multiplexing, W-CDMA.
