The general packet radio system (GPRS) provides packet radio access for mobile Global System for Mobile Communications (GSM) and time-division multiple access (TDMA) users. In addition to providing new services for today’s mobile user, GPRS is important as a migration step toward third-generation (3G) networks. GPRS allows network operators to implement an IP-based core architecture for data applications, which will continue to be used and expanded for 3G services for integrated voice and data applications.

GPRS due to its wireless infrastructure is characterized with the following benefits: open architecture, IP services, same infrastructure for different air interfaces, integrated telephony and internet infrastructure, leverage industry investment in IP and service innovation independent of infrastructure.

Mobility management is one of the major functions of a GPRS . In this talk the tasks of mobility management ( paging, attach, detach), Packet Data Protocol (PDP) context handling, intra- and inter- SGSN routing area update are discussed.
