Abstract: Optimising available radio resource efficiently to the diverse traffic categories in a heterogeneous interworking network, is the key issue of radio resource management (RRM). In this paper, an advanced RRM method specified as dynamic application centric resources provisioning algorithm (DAC-RP), to provide users with a dedicated set of suitable channels to real-time (RT) and non-real-time (NRT) services based on bandwidth conditions, to maximise the capacity with satisfied QoS constraints is proposed. The DAC-RP is realised over an ultra mobile broadband (UMB)-worldwide interoperability for microwave access (WiMAX)-wireless local area network (WLAN) hybrid interworking network, linked over novel intelligent internet protocol (IIP) architecture. IIP, an unified architecture, obtained by the merging IMS call session control functions (CSCFs), application services, enhanced IMS and centralised services, under a single layer with a common set of control and routing functions, to converge the heterogeneous protocols, functional entities and applications. The competency of the IIP and DAC-RP is validated by comparing the performance metrics of RT and NRT applications, simulated for the IIP based UMB-WiMAX-WLAN network developed using the OPNET to the scenario with existing IMS and UMTS-WiMAX-WLAN network.
