摘　　要：基于Parlay业务规范的开放业务技术是下一代网络研究的重要内容。虽然Parlay业务规范目前已经被电信界普遍接受,但是,Parlay业务规范是否可以满足现在和未来电信业务发展的需求,这仍然是一个尚未解决的问题。论文通过构造两个典型的移动业务模型,并基于Parlay业务规范,设计了相应的实现模型,论证了Parlay业务规范对移动业务的支持能力。为了保证实现模型的正确性,论文采用通信顺序进程(CSP)理论描述了移动业务实现模型。最后得出结论:Parlay业务规范在跨业务管理域的业务调用、用户身份验证和用户业务逻辑传递方面仍然无法支持业务的移动性。Open service technology based on Parlay specifications is one of the important works in the researches of next generation networks. Although the Parlay specifications are widely accepted by telecommunication industry, it is still an unsolved question whether the Parlay specifications can meet the requirements of telecommunication development both at present and in the future. This paper tries to validate the supporting of Parlay specifications to the service mobility by building two typical mobile service models and designing correspondent implementation models based on Parlay service specifications. In order to guarantee the correctness of the models, it applies communicating sequential processes (CSP) theory to describe the implementation models. It concludes that Parlay specifications can not support service mobility in following aspects: service invocation, client authentication and service logic transferring across different service domains.
