GPRS Mobility

GPRS is the technology that provides packet data access to the existing GSM networks. It is designed to support an efficient mobile packet network. One of the greatest advantages of GPRS is that it allows a subscriber to access data services at a higher data rate while on the move. Therefore, mobility is a key requirement for wireless data networks. This course explores the issues of providing mobility within the GPRS network, such as how the mobile moves from cell to cell, as well as from Serving GPRS Support Node (SGSN) to SGSN. Roaming issues for packet data services are explored as a subscriber moves beyond their home service provider’s coverage area. GPRS has specified GPRS Roaming Exchange (GRX) to enable data roaming between operators. The course discusses how GRX enables roaming and the different services provided by GRX operators. At the end of the course, both equipment manufactures and services providers will have an understanding of all the issues involved in packet data mobility and how they are resolved in GPRS networks.
