RF Optimization for Call Setup and Analysis of GSM Network Using Agilent Tools

The Call Set up Success Rate, successful handovers, and maintaining the quality of call are most important features used by all mobile operators. So, it is extremely necessary and mandatory to identify possible means to measure these parameters and eliminate the existing problems in a GSM network. Therefore the different operators can use various type of optimization process. How to optimize the GSM coverage area successfully along with better service is the real challenge. In this paper the main motive is to identify the causes of call setup failures in a GSM service test area and necessitate steps to increase the call success rate using RF optimization. RF optimization consists of drive testing, post processing, data analysis, recommendations and action steps. Optimization will be continuous and iterative process of improving network quality. By successful optimization, the Quality of Service, reliability and availability of RF Coverage area is highly improved. RF optimization is used to make proposals on how operators can optimize radio resources as well as provide the required of service quality to the subscribers. Since call drop and call failure are the major problems in the GSM networks. So this RF optimization technique helps to solve this problem.
