“…Pool 2 will be shared between the handoff voice traffic and handoff data traffic. The complete sharing strategy has been proved to have a better system utilization among the other channel allocation strategies [4] [2]. Therefore, the complete sharing strategy is adopted in each partition.…”

The demand of voice and data services on the Global System for Mobile Communications (GSM) is unprecedented in the annals of the history of telecommunication systems. As a result, grade of service (GoS) is no longer stable in the face of this high demand. This paper explores the use of prioritized multilevel Access Allocation (PMAA) scheme to stem the instability of data services when there is high demand. This paper classifies calls into Handover (HD), Real-Time (RT) and Non-Real-Time (NRT) based on the nature of their service and thereafter, priority was set among them. The HD has the highest priority followed by RT and NRT respectively. The channels in the cell were partitioned into three pools named as q 1 , q 2 , and q 3. Data and voice calls have different characteristics, therefore, voice always have priority over data since it cannot tolerate delay in call processing. The q1 is reserved for voice only, q3 reserved for data only while q3 is reserved for handoff calls for both voice and data. General Terms GSM Networks

“…There are three different resource allocation strategies for integrated voice/data services, i.e., complete partitioning, complete sharing, and partial sharing [26]. The results in [26] shows that the complete sharing strategy gives better system utilization than the other two strategies. Therefore, the complete sharing strategy is adopted in this work.…”

Next generation of wireless cellular networks aim at supporting a diverse range of multimedia services to Mobile Terminal (MT) with guaranteed Quality of Service (QoS). The challenge is to maintain the playing continuity of multimedia streams during handoff. In this paper, a bandwidth reservation scheme based on mobility prediction is proposed, to enable high accurate prediction of next crossing cell (target cell) which a MT is going to, in order to avoid too early or over reservation resulting in a waste of resources. The amount of bandwidth to be reserved is dynamically adjusted according to (a) the current position (location) and the extrapolated direction of MT and; (b) the sector and zones of the cell. A Call Admission Control scheme (CAC) is also considered to further guarantee the QoS of real time traffic. The performance of the system is evaluated through discrete event simulation of the wireless cellular environment. Simulation results show that the proposed scheme as compared to several existing schemes is able to reduce the Handoff Call Dropping Probability (HCDP) of real time traffic and the number of terminated ongoing calls of non-real time traffic. In addition, it is efficient to reduce the number of cancelled reservation and subsequently increase the system bandwidth utilization.

“…However, in modern networks, the ratio of source population and the capacity of a system is often limited and the value of traffic load offered by calls of particular classes is dependent on the number of occupied bandwidth units in the group, i.e. on the number of in-service traffic sources [30], [31]. Such systems are described by the Generalised Multiclass Engset Model (GMEnM) [30]- [35].…”

This paper presents a new approximate calculation method of the occupancy distribution and the blocking probability in switching networks which are offered multi-service traffic streams generated by a finite population of two-state sources. The proposed method belongs the class of methods known as the effective availability methods. The basis of the proposed calculation algorithm is the occupancy distributions in interstage links as well as in the outgoing links (forming outgoing directions). These distributions are calculated with the help of the full-availability group model and the limited-availability group model. The results of analytical calculations of the blocking probabilities are compared with the simulation results of threestage switching networks with infinite source population, and, therefore, the validity of the assumptions used in the model is proved.
