A cellular network like a GSM network is built up using a number of base stations to cover a large geographical area. The area covered by one base station can be seen as a cell in the network. Regardless of the location of a user the network should b

Mobile networks produce a huge amount of spatio-temporal data. The data consists of parameters of base stations and quality information of calls. The self-organizing map (SOM) is an efficient tool for visualization and clustering of multidimensional

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
