Analysis of Efficient Queueing Management with Multiple priority calls in Multimedia Personal Communication Services
Dong Chun Lee · 2000
Channels make use of queueing sheme for reducing blocking probability of calls in personal communication system(PCS). In this paper, we propose the queuing model of multiple priorities traffic control mechanism which multiclass calls can wait in the queue under multimedia Personal Communications System(MPCS). This queueing model is based on Head of Line(HOL) method which has time priority. The analytic model is shown blocking probability, and mean waiting time of multiple priorities traffic according to threshold value, priority calls. The proposed analytic model is verified by performing the simulation language, SLAM II. We can see that each calls of MPCS is important to reduce the blocking probability and mean waiting time by changing dynamically performance parameters as threshold value, queue size, traffic density, and mixing ratio of priority traffics.
