“…In the call admission control mechanism proposed in [1], each station independently reserves a number of channels in order to guarantee a specified probability of handoff call drop is not exceeded according to predetermined quality of service. The reserved handoff call channels, which are reserved for handover change dynamically in order to respond to the varying traffic conditions in the cell.…”

Cellular mobile communication Networks have many services and each type of Services has distinct characteristics and Quality of Service requirement. It is important issues in 3-G and beyond networks are to prepare a framework for multiple class service, which performs call admission and handoff efficiently. There have been handful existing mechanisms for improving Call Admission Control (CAC) and Handoff Techniques in mobile network but most of them have considered only single class of service or might have touched value of few classes but not beyond. In this paper we have considered 8 types of services, which are differentiated according to their: Acceptable delay in transmission, Buffering capacity, Transmission mode and Bit rate. In this approach CAC and Handoff issues are resolved by awarding calls with some Priority Number by which each call will be recognized. Another issue of collision in CAC and handoff will be resolved by priority and authority to access the channel. Performance of this framework for CAC and Handoff is evaluated by calculating Call Dropping probability and Call Completion probability in this paper.

“…In fixed multi-rate networks, each class has a particular arrival rate and holding time, while in mobile multi-rate networks, the amount of time each mobile host spends in the cell has to be also considered. The cell dwell time has been shown to follow a generalised gamma distribution [9], but could be approximated with an exponential distribution [2] [3]. The cell dwell time affects the average call holding time for each class as well as the handover rate, and these in turn Eryk Dutkiewicz is now with Motorola Australia Research Labs.…”

This paper investigates the use of fixed bandwidth reservation for multi-service mobile networks. In particular it extends previous fixed multi-service network results to the mobile scenario and presents analytical and simulation results for new and handover call blocking probabilities. It also investigates the performance sensitivity to different traffic load ratios as well as the cell dwell time distribution. Disciplines Physical Sciences and Mathematics Publication Details

In mobile Networks each type of Services has distinct characteristics and QoS requirement. The important issues in 3-G N/W are to prepare a framework for multi-class services to perform call admission and handoff efficiently. The available Call Admission Control (CAC) and Handoff Techniques in mobile network have considered only single class of service or have touched value of few classes but not beyond. In this paper we have considered 8 types of services, which are differentiated according to their Acceptable delay in transmission, Buffering capacity, Transmission mode and Bit rate. In this approach CAC and Handoff issues are resolved by awarding Priority Number to each cal, which will also resolve issue of collision in CAC and handoff. Performance of proposed frame-work for CAC and Handoff is evaluated by calculating Call Dropping probability and Call Completion probability.
