EDGE for Mobile Internet

The General Packet Radio Service (GPRS) allows an end user to send and receive data in packet transfer mode within a public land mobile network (PLMN) without using a permanent connection between the mobile station (MS) and the external network during data transfer. This way, GPRS optimizes the use of network and radio resources (RRs) since, unlike circuitswitched mode, no connection between the MS and the external network is established when there is no data flow in progress. Thus, this RR optimization makes it possible for the operator to offer more attractive fees.
