Analysis of cell reselection in evolved UMTS radio access network: Radio Resource Allocation

Radio Resource Allocation (RRA) is a key challenge in every wireless communication generation. Due to scarcity of wireless spectrum, resources are shared based on requirement. We can find there is a tradeoff between availability and utilization of resources. However resource requirement also changes varying with user request, certain network failure incident, or time varying consumption patterns. In Long Term Evolution (LTE) reselection process is defined to facilitate user requirement. In our work we have analyzed all aspects of cell selection process and highlighted challenges and solutions to optimize resource management.
