Research And Implementation In Mobile Station Testing Set Of The Signaling Protocol On The Radio Interface Of GSM Mobile Communication System

With the impetuous growth of mobile communication system,it brings a rapid increase in mobile communication testing and repair market correspondingly.At the same time,because of the competition of the 3G mobile communication standards and long time's waiting for the 3G system's commercial use ,the mobile communication testing market still gives the leading position to 2G productions.To be the representation of 2G mobile system ,GSM's successful using for business in china makes the demand for GSM testing equipment rising dramticallyo And so the maket expects good mobile communication testing equipments which are made in our country.According this actuality ,The Wuhan University of Technology and The Wuhan ZhongYou Company empolder the GSM Mobile Station Test Set in the project.lt is designed for the requirements of testing GSM mobile station and supports all the required protocol for estimating GSM900/1800 dual-frequency mobile station.According to the research to radio-interface of GSM,the central control module CCM's CPU processor accomplishes the Layer2,Layer3 protocols' function of the radio-interface part to implements the location updata to MS ,MS Call,BS Call,and then provides testing and service based on the link between MS and the test set.
