摘　　要：设计了一个基于SLP协议的带上下文感知能力的服务发现模型――SBCAS。将一个上下文感知系统构建于DA(目录代理)与UA(用户代理)的通信之间,对DA产生的查询结果作进一步过虑以得到符合当前环境和用户需要的服务。上下文感知系统能通过各种传感器感知当前工作环境的各种信息,并以此影响整个查询系统的行为及查询服务的结果,使SLP协议更加智能化。最后通过模拟实验证明了SBCAS系统确实能够在用户最少干预的情况下,得到最满足当前需要的服务。A service discovery model with ability of context-awareness based on SLP protocol --SBCAS is proposed in the paper. The context-awareness system is built on the communication between DA and UA, in that to take the further filter of original query result to fit the current need of user. The context-awareness system can sense various kind of information of current working envi- ronment with these sensors, and then use them to influence the behavior of the whole enquiry system and the finally query result, and this can make the SLP protocol more intelligent. In the last of the essay, the experiment proved the context-awareness system really can get the appropriate service with the least user interference.
