摘　　要：针对IMS中业务交互管理问题,本文首先介绍和分析了IMS中现有基于过滤规则的业务触发机制和存在问题,然后针对3GPP标准中新增的SCIM实体,介绍了相关研究现状和改进方式,最后分析了现有业务交互管理中存在的问题并提出下一步发展方向。Aiming at the service interaction problem in IMS, we survey and analyze current research and applications, as well as existing problems. Firstly, we look into the service triggering mechanism based on filter criteria and analyze remaining problems in it. Secondly, we review current research and applications on service capability interaction manager （SCiM）, whichis known as a newly added entity in 3GPP＇s specifications. At last, we point out the existing problems in SCIM research and propose further research.
