“…The relationship between the BLER switching thresholds and coding schemes can be found in [11][12][13] where reference thresholds are provided to switch among the four coding schemes in the GPRS networks. The improvement of acknowledgement procedures at the RLC level, the effect of correlation in multi-slot transmission, and the impact of imperfect LA can be, respectively, found in [14][15][16].…”

A teletraffic analysis for the performance evaluation of the joint use of Dynamic Resource Allocation (DRA), Channel De-Allocation (DAS), and Channel Re-Allocation (RAS) strategies in GSM/GPRS networks is developed. In addition, an efficient DRA strategy with a link quality awareness policy, Channel De-Allocation and Re-Allocation policies as well as user prioritization (called DRA LA DAS RAS) is proposed. To the authors' knowledge, most related works have either studied Link Adaptation (LA) or Dynamic Resource Allocation (DRA) strategies as independent topics but have failed to address their combined effect on GSM/GPRS systems. DRA LA DAS RAS uses both call degradation and call compensation techniques. Calls with the largest number of channels allocated and the worst link quality are degraded first. Conversely, calls with the lowest number of channels allocated and the best link quality are upgraded first. This allows upgraded calls to release resources more rapidly, making them readily available for new calls. Numerical results show that the proposed DRA LA DAS RAS strategy significantly improves system performance, i.e. up to 82% (74%) {58%} [37%] <27%> less blocking probability relative to the DRA (DRA LA with p=0.75) {DRA DAS} [DRA LA DAS with p=0.75] strategy.

In this paper, the performance of dynamic resource allocation and channel de-allocation in integrated voice/data wireless networks with link adaptation is mathematically analyzed and evaluated. To our knowledge, all previous related works published in the literature have considered only link adaptation (LA) or dynamic resource allocation (DRA) separately. Additionally, a DRA strategy with link quality-aware prioritized channel de-allocation (called DRA LA DAS) is proposed. With the DRA LA DAS scheme that calls with the greatest number of channels and the worst link quality are degraded first. In this way, in DRA LA DAS preference is given to data users with good quality link which, on average, retain resources less time than data users with bad quality link. Numerical results show that the proposed DRA LA DAS strategy significantly improves system performance. The GSM/GPRS system is used as a case study. The GSM voice new call blocking and forced termination probabilities, GPRS packet dropping probability, average GPRS packet transmission time, and channel utilization are analyzed.
