Question

Draw functional architecture of a GSM system and explain.

Answer 1

The GSM network architecture provided a simple and yet effective architecture to provide the services needed for a 2G cellular system.

There were four main elements to the overall GSM architecture and these could often be further split. Elements like the base station controller, MSC, AuC, HLR, VLR and the like are brought together to form the overall system.

The 2G GSM network architecture, although now superseded gives an excellent introduction into some of the basic capabilities required to set up a mobile phone network and how all the entities operate together.
