Aiming at the feature interaction in the next generation network（NGN）,this paper summarizes and sorts the existing feature interaction,and decides to solve the problem with Service Broker.Then,based on compatible class,a new solution to feature interaction and a new architecture of Service Broker are pr esented,and the new procedure of service trigger is analyzed in detail.Experim ent proves that the new Service Broker can resolve feature interaction effective ly.%针对下一代网络（Next Generation Network,NGN）中的业务交互问题,提出了一种新的Service Broker架构,解决了业务交互中的共享触发类和无限循环类这2类主要的业务冲突问题。论述了Service Broker系统在网络架构中的地位,并设计了一种基于兼容类的业务交互解决算法,对新的业务触发流程进行了详细分析。实验证明,该Service Broker模块可以有效地解决业务交互问题。
