Call Admission Control and Resource Utilization in 3G Networks?

Every newly developed technology faces the challenges to justify its potential and become alive in a real working environment. Combining two of the leading new technologies, GPRS and multicasting in the field of mobile communications makes this challenge even more exigent. At a time when radio and core network resources are utilized at maximum, multicasting has the potential to improve overall resource utilization and as result to provide more channels for voice or data transmission. This also significantly improves the quality of the service and allows applications with high bandwidth demands such as streaming video and viceo conferencing to be widely promoted. In this we will focus on studying the impact of multicast implementation on GPRS platforms. From the analyses of the output results from the system simulator we will determine the multicast influence on a GPRS and different network loads, number of users and multicast density modes. We have studied the impact of packet delays and packet overflow which is in close relation to the Quality of Service provided by the system.
