ABSTRACT
With the third generation mobile communications technology gradually entering the commercial phase of large-scale, the introduction of new business after another, the number of users has become increasingly onerous. Therefore, operators have to continuously optimize the system to achieve the optimal allocation of system resources, so that the WCDMA wireless mobile communication network resources and the best performance in running the state, the only way to within a reasonable cost for customers the greatest degree of satisfaction with services.
The charm is in the high-speed 3G data and multimedia services, and video telephony, video streaming, gaming and other high-speed data services requires a good wireless network, wireless network performance will directly affect the user experience and operator revenue . The wireless network optimization, a key factor for success.
The main content is based on the existing WCDMA network and the network optimization. Based on the WCDMA 3G mobile network technology research, spells out the basic method of wireless network optimization and process, and WCDMA network optimization for some common problems, specific solutions are given and means.
