Dynamic radio resource management in GSM/GPRS using scalable resource allocation technique

Abstract

A scalable resource allocation (ScRA) algorithm is developed to improve the mobile network radio resource utilization. The traditional mobile dimensioning is based on the "busy hour" traffic intensity, and this static resource allocation (StRA) methodology does not seem to be able to provide efficient radio resource utilization for the future/present multiservices environment, with their expected spatially and temporally varying loads. This is a hindrance for the introduction of wireless IP based services, for which the demand is rapidly increasing. This paper provides an extension analysis by incorporating single slot FIFO and single slot round robin (single slot RR), blocked-call cleared (BCC) and blocked-call delayed (BCD) strategies in the ScRA scheme. By employing the ScRA scheme in an example GSM and GPRS network, we specifically investigate and evaluate the system throughput for both the circuit-and packet-switched networks. The findings show that single slot FIFO ScRA and single slot RR ScRA schemes obtained no difference in system throughput. On the other hand, when BCD is implemented in the ScRA scheme, there is significant throughput gain.
