In a GSM cellular system, and generally in any cellular system, the operator has to carry an essen- tial task of optimizing the system which is an ongo- ing need for the life of the system operation. Optimization is normally understood as the tuning of the radio interface in order to offer the sub- scribers the best quality. Optimization is normally benchmarked against some performance parameters of the system: drop call rate, call establishment suc- cess rate, subjective quality, bit error rate measure- ments, etc. The operator normally gets the data he needs to optimize a cellular system in a variety of forms: drive testing the system, statistics provided by the system, subscriber surveys/complaints, etc. From this data, the operator determines the actions needed: tuning of radio database parameters, anten- na modifications, new sites needed, etc.
