Wideband Code Division Multiple Access is an optimized version for 2.5G and 2.5G GPRS. WCDMA can be said to be a 3G wireless mobile technology basically used for fast data transfer transactions in form of voice, data applications to internet surfing and other several online operations. WCDMA was designed primarily intelligent systems and others smart phones due to its high speed internet accessibility. In  recent times, network has drastically reduced in its efficiencies due to increase in the number of intelligent systems and smart phone users, this has posed a great challenge to internet providers on the quality of service they render to their subscribers especially on the rate of call drops. Based on the stated observations, this work is geared towards providing an improved congestion mitigation approach by employing fuzzy logic technology to better the quality of services to subscribers. The optimization was stimulated using a Matlab fuzzy tool, the result showed a great deal improvement on the network congestion. This was done using Fuzzy optimization intelligent system which monitors incoming cell by accepting mean bit rate, reject mean burst rate, monitor and constantly adjust its queue capacity whenever network instability or variation is experienced and feeding the quality of service at every end of the service. The system intelligently and constantly re-adjusts until an optimum quality of service is attended
