In the GSM General Packet Radio System (GPRS), a mobile station (MS) must be located at the cell level before a downlink data transmission can proceed (MS- terminated data transfer). During this location discov- ery process, the MS must identify itself to the network using a unique identity in order for the network to accurately transmit the data packet within the correct cell. This process requires the exchange of several sig- naling messages, which contribute to the packet trans- fer delay and consumes radio channel resources. GSM PAGING PROCEDURE In GPRS, the paging procedure requires at least 4 messages.
