With the introduction of digital cellular mobile networks, such as GSM, mobile telephone users experienced the freedom of traveling and always being connected. Even with a call in progress it is now possible to move from one radio cell into another without the call being interrupted. The action of switching a call in progress from one radio channel to another to secure the continuity of an established call is named handover. Originally this was the case for circuit switched voice and data connections. As GPRS is based on the 2G GSM network, handover is working with packet switched data connections as well. In the packet switched domain handover is known as routing area update (RAU).
