Call Admission Control Scheme And The Desire For Prioritization In Mobile Networks

The wireless communication system usually called the global system for mobile communication (GSM) has been a great catalyst for the telecommunication industry. Since its inception in Nigeria in the late 1990’.There have been tremendous increase in the number of subscribers to the various network providers available. This increase in demand has led to traffic congestion due to the limited frequency spectrum available. An easy approach to solve this problem is to increase the network capacity, but this is uneconomical because even at their current size, the network are under-utilized during off peak period and very congested at peak period. Call admission control and prioritization of hand off are necessary tools for the effective management of the network for a better quality of service (QOS) to the consumers. This paper provides a survey of admission control scheme and handoff prioritization for cellular network several (CAC) schemes are discussed with handoff prioritization being a common characteristic of these schemes.
