“…In the past, a few literatures have proposed and studied different channel allocation scheme such as channel reservation, non-preemptive or preemptive queueing priority, dynamic channel allocation, channel deallocation scheme [6][7][8][9][10][11][12][13][14][15]. Lin et al [14,15] compared the performance of several proposed channel allocation schemes and the authors suggested that a dynamic channel allocation scheme with buffering mechanisms could provide flexible and better performance.…”

In this paper, we analyze the performance of GSM/GPRS networks with the emphasis on the study of the adaptive characteristics implied by multi-slot capability. Previous work employing the multi-slot service commonly assume that one or two channels are required by a GPRS data request for the sake of analytical simplicity. In this paper, we remove this assumption and generalize the GPRS data channel requirement (M channels). In addition, we propose a channel re-allocation schemes (RAS) upon channel release by re-allocating the released channels to the GPRS data which is currently using less than M channels with the potential to fully utilize the available resources.The result shows that RAS can significantly decrease the voice call blocking probability and the GPRS packet transmission time, and simultaneously increase the channel utilization with negligible penalty on GPRS packet blocking probability. Small M (e.g.M = 2) will underestimate the performance achievements of the prior channel allocation scheme as well as RAS, which shows that the multi-slot capability in GPRS network is able to increase the system performance.

“…The packet-switching makes the resource allocation issue in GSM/GPRS different from that in cellular and PCS since the channel allocation schemes previously proposed for cellular and PCS do not distinguish different requirements in bandwidth between voice and data services, i.e., the slot numbers allocated for voice and data requests are equal; however, the number of slots allocated for data in GPRS is flexible based on the demand-basis. In the past, only a few papers have addressed this issue in the integrated GSM/GPRS system, e.g., [8], [9], [11], [13], [15], [17]. [8] tried to identify that how many channels should be allocated to GPRS sessions using the Markov-Modulated Poisson Process (MMPP) to model data traffic.…”

We propose dynamic channel allocation schemes which employ techniques such as channel reservation, service priority and queueing strategies (with or without threshold control) etc. Using these techniques allows system designers to differentiate Quality of Service (QoS) requirements (e.g., new call blocking/handoff forced termination probability and delay) required by different types of service. Via the simulation approach, the improvements offered by different strategies under different parameter sets and different network situations are investigated. The results obtained in this paper provide system designers guidelines of how to provide an excellent channel allocation scheme and how to choose suitable parameters in the integrated GSM and GPRS system.
