Abstract


General Packet Radio Service (General Packet Radio Service) referred GPRS is a digital cellular network ( GSM , DCS, PCS) new data business , which uses sublet end-to-end wireless rules in GPRS or GPRS terminal message ( such as end-user to the network transmission protocol IP and X.25 ) . In the transmission of data services , GPRS- packet switched mode is more effective than the GSM circuit-switched mode . This paper first introduces the GPRS system 's business structure , network node ; combined with the actual work of the author , a brief introduction of the the Motorola GPRS device structure and function . And then focus on the factors that affect the GPRS data transfer rate on the wireless interface , analysis and discussion of the impact of these factors on the transmission rate and specific optimization suggestions , also discussed in detail the encoding technology of data transfer rate , and gives the specific test program . Finally , Tianjin Mobile Communications Corporation GPRS network using the CS-3 / CS-4 coding scheme is suggested. Of engaged in the construction work of the mobile GPRS network in Tianjin from 2002 , after more than two years of efforts to complete the work of the mobile GPRS network construction in Tianjin , during which conducted the feasibility study of the project , engineering design, construction and implementation , network optimization , problem analysis and fault handling a lot of work . In the meantime , I am on the GPRS network and related technology research, and identify and solve many practical problems , has a certain significance and practical value of the work on the implementation of the Tianjin mobile GPRS network optimization .
