The General Packet Radio Service (GPRS) is a new bearer service for GSM tha
t greatly improves and simplifies wireless access to packet data networks,
e.g., to the Internet. It applies a packet radio principle to transfer user
data packets in an efficient way between mobile stations and external pack
et data networks. This tutorial gives an introduction to GPRS. The article
discusses the system architecture and its basic functionality. It explains
the offered services, the session and mobility management, the routing, the
GPRS air interface including channel coding, and the GPRS protocol archite
cture. Finally, an interworking example between GPRS and IP networks is sho
wn.
