Abstract:	3GPP has standardized IP multimedia subsystem (IMS) as the solution for multimedia service delivery based on Internet for future next-generation networks (NGNs) and it aims to merge Internet and wireless cellular networks together in order to enable rich multimedia services. The home subscriber server (HSS) is a crucial entity in IMS, which provides the functions such as access authentication and authorization as well as service data management in GPRS and CS domain. However, it still cannot provide the automatic service selection to help the users access application servers according to their demands and contexts. This paper proposes a novel context-aware service selection approach which helps perform service selection according to individual user`s contexts such as the preferences and habits. This approach includes two main components which are set in HSS. One is context management and the other is selection engine, which employs the dynamic fuzzy analysis hierarchy model (DFAHM) to conduct service selection according to the contexts. Based on the quantified dynamic and fuzzy evaluation, the DFAHM helps select the most suitable services for the users. And, the model evaluation is presented to verify the feasibility of DFAHM. The results show that the DFAHM helps achieve service selection according to the users` contexts.
