The goal of this chapter is to give an overview about the architecture of GSM and GPRS networks, and introduce to the reader the protocols used for mobility management and call control at the core network. To make it easier to understand the way in which the protocols work, we give many examples to help the readers in his studies. We show how the location update takes place, how the calls are originated and terminated, how the short messages are handled, et cetera.
