Abstract: While next generation wideband wireless communications network can provide the users high speed service, image or video information transmission and high speed access Internet services, it brings the new challenge for system’s handover scheme. The former handover scheme which only considers the sole factor of the system is not suitable for the next generation wideband wireless communication network. This article uses the fuzzy logic technology to carry on the select of goal cell in handover scheme. Compared with the traditional methods, the fuzzy logic technology may give attention to many kinds of factors to provide more reasonable selection result and also can balance the load of the system, reduce the reject rate of handover.

Key words: fuzzy logic, handover, resource management

摘要： 下一代宽带无线通信网在为用户提供高速率语音服务以及图像、视频信息的传输和高速接入Internet服务等丰富的业务类型的同时，也给系统的切换策略带来新的挑战。以往仅考虑单一因素对系统影响的切换策略已不适用于具有丰富业务类型的下一代宽带无线通信网络。该文利用模糊逻辑技术进行切换过程中的目标小区选取。相比传统方案，模糊逻辑技术可以兼顾多种因素，使得选取结果更加合理，并且可以均衡系统负载、减少切换的拒绝率。
