Research Of CDMA Wireless Network Optimization Technology Of JINZHOU Telecom

As China Telecom CDMA2000network construction scale increasing, thenetwork operation quality and service level face more severe tests. In order to ensurethe rational allocation of CDMA2000system resources, effectively solve thenetwork problems, make network operation and network service quality greatlyimproved, the research of CDMA2000wireless network optimization technology isimperative. This paper aimed at CDMA2000network optimization of JINZHOUtelecom based on the basic method and process of network optimization. On thebasis of the mastery of CDMA2000network structure and basic principle, we havenot only carried on the RSSI check optimization, adjacent regions optimization andsome similar implementation of the network optimization, but also made thenetwork optimization analysis for several typical cases of JINZHOU Telecom.The main content of this paper includes the following aspects:First of all, we show the overview of the development of mobilecommunication, simply introduce the evolution of mobile communications from1Gto4G. Based on the evolution of mobile communications, we introduce the researchsignificance of wireless network optimization, the paper content and organizationalstructure.Secondly, we summarize the CDMA2000system which is used by ChinaTelecom, including the evolution, network structure, basic principle (CDMA2000code sequence, forward/reverse channel, system communication model) and keytechnology (power control, soft switching, diversity) of CDMA2000.Thirdly, we show the CDMA2000network optimization and implementation.We briefly introduce the content, process, classification and testing methods ofnetwork optimization, and implement the RSSI examination optimization, adjacentregions optimization, multiple carrier frequency optimization of CDMA2000of JINZHOU Telecom.Finally, we analysis the cases of CDMA2000network optimization ofJINZHOU Telecom, containing the JINZHOU Normal Training College EVDO notconnected case, JINZHOU red eagle village EVDO call failure case, JINZHOUBSC2boundary1X drop phone case. We make the problem description, problemanalysis, network optimization and optimization effect for the three typical cases.
