2.5G Mobile Networks: GPRS and EDGE
Sumit Kasera, Nishit Narang, and A.P. Priyanka( http://www.tatamcgrawhill.com/)
The GPRS edge
The GPRS (general packet radio services) core network has two types of entities, viz. databases (or registers) and routers, says 2.5G Mobile Networks: GPRS and EDGE by Sumit Kasera, Nishit Narang, and A.P. Priyanka. They explain how “GPRS emerged as the first genuine packet-based wireless technology,” by reserving RR (radio resources) only when data is sent, in services such as Internet access. An important advantage of GPRS, the authors observe, is that it provides a migration step towards 3G (third generation) networks.
