Research On Optimization Of GPRS Networks

As the 2G mobile technology ,GSM provided the data service only based on the circuits, which can not satisfy speed demand of the people. GPRS was the further development of GSM, provides the higher data speed service to GSM. The emergence of GPRS supplies GSM original shortage of data service. The GPRS network's appearance, makes the network optimization work to optimize from the traditional pronunciation quality to optimizes excessively gradually take the data as in the key goal.In this thesis the author first introduced the composition of GPRS network and the signaling structure, and have carried on the description to each kind of channel's structure and the code type. Then, through to GPRS network present situation's enumeration, introduced the problems in the network optimization. In view of these questions, obtains from the GPRS success rate of access and the transmission speed, through carries on the multianalysis to the crucial target and the signaling flow, classifies deals with the GPRS network issue daily the solution method, forms the quite complete optimized processing mentality. Finally provides a series of illustrative cases according to the present stage promotion data traffic's experience and the method.The author unifies the practical work, puts forward the the success rate and the transmission in GPRS wireless network of Tianjin ,through from aspects and so on statistical target and signaling flow analyzes, summaries promotes the GPRS wireless target the processing method and the overall mentality. In GPRS wireless network optimal process, only then bases on the foundation principle, has the analysis question method, summarizes the processing question method, can the effective addressing each kind of network question.
