In GSM networks, call blocking, call dropping and bad voice quality are the most common types of service quality problems. The occurrence rate of these problem types is closely connected with the size of the cell served by a BTS. Large cells tend to generate more input traffic and call blocking may occur. Also, the radio signal quality may not be adequate in the border of large cells, causing bad voice quality and call dropping. The size of the cell can be controlled by adjusting, for example, the minimum received signal strength that is required when MSs initiate new calls. In this paper, a model suitable to compute the cell size adjustments that minimise the occurrences of call blocking, call dropping and bad voice quality is presented. The model is based on model estimation from massive data records as well as intensive use of well-known theories of mobile communication.
