Analyzing the Mobility of Parlay-Based Services
Shen Su-bin · Journal of Nanjing Institute of Posts and Telecommunications · 2004
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.
