Enhanced Common Radio Resources Managements Algorithm in Heterogeneous Cellular Networks

Deployment of new radio technologies in the mobile world has not been more critical than it is now. The customers and applications have been starving for more data throughput while operators are struggling to deliver the promised high data rates to customers. Operators are using existing traffic information from GSM/GPRS technologies to deploy WCDMA and HSDPA systems. The deployment of WCDMA in the existing GSM/GPRS cell sites has proven to enhance the network resources available to the operators. The diversity of the services and the availability at the moment of two radio access networks to choose from to deliver these services makes the management of available resources rather complex. Therefore, Common Radio Resources Management (CRRM) has been standardized by 3 GPP. Radio Access Technology (RAT) selection is a key element for CRRM. In this paper, we propose a new algorithm to optimize the available network resources in multi radio environment based on service requests. The proposed algorithm efficiently optimizes the radio resources available based on the services supported in 3 GPP standards.
