Features: Upgrading from GSM to GPRS systems requires relatively small investments in hardware and software, allowing for the maximum utilization of existing systems. Since GPRS is a packet data service, it eliminates the need for dial-up access for users to connect to the internet, enabling "always online, pay-as-you-go." For operators, it improves resource utilization and reduces operational costs. Additionally, through software upgrades to SGSN in the GPRS system and the use of shared GGSN, a smooth transition from the 2G GSM network to the 3G UMTS network can be achieved. This book provides a comprehensive and detailed analysis and introduction to the development background, overall structure, protocol stack, services offered by GPRS, air interface, transmission, WAP applications, and the transition to the third generation. It serves as an excellent introductory guide for technical personnel and university students in related fields to learn and understand GPRS technology.
