GPRS is a packet switched access mode for GSM systems, which will enable more efficient use of the radio resources leading to increased data speeds and capacity. It is an important migration step toward 3G networks. This course provides a detailed analysis of the workings and implications of GPRS.
Review of GSM architecture, the new network entities required for GPRS. How the existing GSM network entities needs to be upgraded. How GPRS roaming will work. How intra and inter PLMNs work together. How billing works in the GPRS network.
Brief review of IP, IP stack over GPRS, IP addressing in GPRS, DHCP, GPRS configuration for IP. IP packet flows. WAP and GPRS.
Messaging scenarios used over the GPRS Gb, Gs and Gp Interfaces. How the handset performs a GPRS attach and detach. GPRS roaming and how it works. Links used between GPRS Roaming Exchanges (GRX). GPRS terminal attach message flow in the NSS, PDP context message flow in the NSS, GPRS paging message flow, GPRS terminal detach message flow.
The components of the protocol stack. How each component works. How encapsulated packets are sent. How each component links to the next component.
The new GPRS channels required. How the new channels work. How to map GPRS logical channels onto physical channels. How they enable session activation. The difference between master PDCHs and slave PDCHs.
The 3 classes of terminal available. How the handset performs a GPRS attach and detach.
