Abstract

This paper presents a call admission control (CAC) algorithm that aids in the quality of service (QoS) support in a wireless network base station. The threshold access sharing (TAS) scheme provides improved performance over generalized methods of current CAC algorithms. The TAS algorithm relies on a prioritization of admitted traffic through bandwidth thresholds. This is particularly vital for high priority real-time calls and preapproved QoS handover calls. In addition, the CAC algorithm must rely on some advanced levels of channel estimation to most effectively use the limited channel resources
