Dynamic resource allocation of extended policy based network management (PBNM) model in mobile environment
LI Mu-shan · Journal of Jilin University · 2010
The conditions and actions of traditional static policies are constant,which leads to less preferable adaptability to the change of network state. In this paper,a dynamic resource allocation scheme based on extended PBNM model in mobile environment is proposed. This scheme applies the policy with dynamic format and improves the conventional PBNM model by adding the modules that can update policies during runtime according to network state. The method for dynamic resource allocation is described. Experiment and analysis show that this scheme decrease the probabilities of handoff call dropping and new call blocking,while,increases the utilization rate of network resources,which is more flexible compared with traditional resource allocation method.
