Scalable resource allocation algorithm for GPRS

This paper compares the proposed scalable resource allocation (ScRA) and static resource allocation (StRA) schemes for a mixed packet as well as circuit switched traffic sharing a common pool of spectrum. To evaluate the performance, a computer simulation model of a GSM/GPRS system was developed. Results show that the ScRA scheme can optimally allocate radio resources to time varying circuit switched and packet switched traffic while maintaining the specified quality of service (QoS) for each type of traffic. The novelty of the scheme resides in the derivation of a threshold level for the packet switched session for different sets of QoS requirements. This investigation can be used for call admission control in an integrated network.
