Analysis And Simulation Of Software Architecture On Program Controlled Switcher In GSM

Software architecture (SA), which has a place in software development, is the key and base of successful software development. Based on the series of C&C08 digital program controlled switcher, with the method of analyzing from the whole to its portions, by taking out the core part from these switchers, this thesis takes apart and simulate SA of the switcher in the 2nd generation mobile system, which belongs to one research on Domain-Specific Software Architecture.Firstly, this thesis simply describes GSM and expatiates its global structure and the interfaces and protocols between many functional modules. Secondly, the article takes a synoptic analysis of the switcher software in order to grasp its SA. Thirdly, it takes a material analysis of No.7 Signal System, which is the important part of the software system in switcher. Finally, this paper take a detailed analysis of Service Process Module of the switcher ,and summarizes the specialty of SA in one switcher---hierarchy and modularization.
