Abstract
In this paper, we propose a novel call admission control scheme which improves call blocking probabilities as well as the packet–level QoS in the multiservice environment of next generation cellular networks. In our scheme, we suggest that bandwidth–inefficient service sessions such as WWW browsing of which traffic pattern contains frequent think time are grouped dynamically into a set, called lock, and forced to share the bandwidth with others on the basis of on demand round robin instead of being allocated separate bandwidth especially when the resource availability is unfavorable. Compared with the corresponding results of a conventional reconfiguration strategy by the use of simulation study, our scheme shows improved packet delay and loss rate in the case of WWW traffic, and superior performance in terms of blocking probabilities of both new call and handoff cases.
