WCDMA Wireless Network Optimization Of China Unicom Shijiazhuang Branch

The GSM users take over eighty percent an2G times. The WCDMA network definited by ITU uses Rep-R4-R5-R6standard to saving huge invest and making benefit continued. The transition way of enhance UMTS ont only optimizes the network resources but also simplify the network structure and operation during the development. Those features show the inheritance of GSM facilities usage.This topic is mainly study on WCDMA radio network optimization method and propagation model calibration, a city, through hands-on, find and handled as softswitch deal with subsequent switching3G Council to cut the low success rate of money problems. Through the implementation of the interim programme cut out of the3G Council success rates by significant escalation; Through the analysis of interface messages, call drop wireless are the main factors of quality problems caused by, including the one with nothing to go with off network failure, and the end user, and so on, optimally solve the wireless environment, improve the level of network operation.
