| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 90 === With the success and popularity of the Second Generation Mobile Systems and Internet during the recent years, there is an increasing demand for convergence of radio communication with packet transmission. The GPRS system, as an extension for the European GSM standard, was produced to cater for packet transmission. The Northern American PACS standard already had data packet transmission functionality in its initial form. This thesis is focused on the comparison between GPRS and PACS/PPC subsystem at the seven important features, including Logical Channel, Mobility Management, Data-link Layer, Power Control, Flow Control, Handset Function, VoIP Packet Service Delay. We also analyze how network design affects the structure, function and application of both subsystems.
