Serving GPRS Support Node (SGSN). A GSM time slot allocated for GPRS is called a packet data chan-nel (PDCH). The radio resources are more efciently used than in GSM, since the PDCHs in a cell are shared between the GPRS users, and not, as in GSM, reserved for one user at a time. Access to the PD-CHs is controlled by the Radio Link Control/Medium

further increase in data rate by means of 'Enhanced Data Rates for GSM Evolution' (EDGE; new modulation: 8PSK). (E)GPRS is simply an extension of GSM and uses physical resources of GSM (phase 2 or 2.5). Packet-oriented data communication means that resources are only used if data is actually to be transmitted. In (E)GPRS, this is referred to as
