Radio Resource Management Strategies in 3G UMTS Network

Third generation (3G) mobile communication system, namely Universal Mobile Telecommunication System (UMTS), will support a wide range of applications with different quality of service (QoS) profiles. At present many of these applications are not possible to predict. Also the usage of the different applications are difficult to predict i.e. it is not possible to optimise UMTS to only one set of applications. Next generation wireless access system will have features and requirements that are quite distinct from current systems, mostly designed for telephony. Such features include higher bandwidth, mixed, packet oriented and strongly asymmetric traffic patterns as well inhomogeneous network architectures. In this paper we have identified some significant problems in Radio Resource Management (RRM) in future wireless IP based multimedia systems and have proposed some potential solutions.
