After two years of development of China Unicom WCDMA network

the number of users is increasing

and the load of network also is gradually increasing

however

shortage of code resource of closely related with user-aware begin to appear

and gradulally result in that network performance began to fluctuate even to deteriorate

such as wireless successful rate is lower than before

single subscriber rate is decreasing.By analysising using of code resource of Changsha WCDMA radio network

this article aims to optimize and settele the problems from the following aspects:the cover control

dual-carrier program

parameter optimization

etc.
