Certain investigations On performance analysis of call Admission control mechanisms For improvement of quality Of service in 3gpp LTE networks

Abstract

In the modern telecommunications there is a development of newlinewide range of innovative technologies Among them Third Generation newline 3G mobile telecommunications is the predominant generation of newlinestandards for mobile devices and mobile telecommunication services newlineLong Term Evolution LTE networks aim to provide integrated services newlinelike multimedia services voice and data through the mobile devices newlineTo handle the heavy user requirements in the mobility management newlineProcess the new mechanisms are evolved to meet the challenges next to newlinethe Quality of Service QoS In an active mobility based environment newlineintegrated services there is a need to have a proper resource provisioning newlinemechanism to provide a high level of QoS newlineCall admission control is an efficient resource provisioning newlinestrategy for the limited number of resources in the networkIt satisfies the newlineQoS requirements based on the quality policies to maximize the resource newlineUtilization Due to the high speed of users mobility call dropping newlineprobability is always high and hence the call rejection rate is very high newlineA key challenge of call admission control scheme is providing efficient newlineresource utilization and guaranteed the QoS for all types of calls newline newline
