Admission Control in Heterogeneous Network: Overview

Rajeshwari C. Choukimath | Vasudha V. Ayyannavar

Abstract: The heterogeneous networks should support a broad range of multimedia services with guaranteed quality of service. In order to support the requirements; a new call admission control is needed to support the integrated architecture. Because rejecting a handoff session would lead to the result much worse than rejecting a new session; service class differentiation is adopted to define the service priority according to service type and handoff type. A new admission algorithm is used for service utility functions to maximize the utility function and balance load of heterogeneous networks; Hence admission control mechanism is effective to the extent. Network operators have been reluctant to deploy IP multicast services mainly due to the lack of native control over multicast groups. This lack of control does not only prevent operators from generating revenue from multicast based services but also hinders regular network management. Hence in this paper we provide a overview that enunciate architecture; that uses the existing Authentication Authorising Accounting (AAA) functionality to perform user identification and multicast session admission control.
