Research Of Client Service System Based On Unstructured Supplementary Service Data(USSD)

As an operator of mobile communication, service is the powerful tool to compete in market and the root to survival and development. It's also become the key point that all operators pursue continually to deepen the connotation of service, widen the area of service and innovate service model as to improve the contentment degree of customer, keep customer and then enlarge the market share under the growing competition of market and service. As a convenient and agile client service method, Unstructured Supplementary Service Data (USSD) has higher speed and ability to interact than Short Message Service(SMS), and it is an effective access method which can adapt most daily need of most ordinary mobile user, and it also is the constitute and important supplement to client service system in existence.This paper analyzes the need of Guizhou mobile communication corporation (GMCC) palmtop client service system (PCSS) in detail, discusses the advantage and possibility of construction PCSS using USSD in GMCC. It presents the work of network alteration, function, service and flow design based on the network status, develop layout and total requirement. The basic work includes:1. It concludes the technique and application character of USSD, the related network structure of USSD platform, explains the handle flow of the interactive response of USSD.2. By analyzing the application type in mobile communication and market benefit of USSD, combining the feature of USSD service platform, it presents the infrastructure of USSD system and application, include composing of core system, deployment of application (assignment of service code, suitable application type and market benefit), and the influence and change to the existent network.3. Basing the status of the network of GMCC and the real requirement of the "service centralized" idea of client service, and after analyzing the relative service flow, it discusses the possibility and presents a proposal of implementation USSD in GMCC existent network, and applies the research work and implementation infrastructure on the construction of USSD based PCSS in GMCC. It is positive to the construction of PCSS of GMCC and obtains the predicted effort.Because it is flexible to exploit new service through USSD, the research anddevelopment of USSD has gained more and more concentrate, and wireless application protocol based on USSD adapt to this situation has then come up. With the development of electronic commerce and the wide application of USSD in wireless area, it is more and more convenient to get information through mobile phone, and the operator who can provide USSD service will have a much expansive market. With the popularization and gradually maturation of USSD application, operators can fully use its GSM network resource, alter their construct thought, and combine USSD, SMS and WAP to satisfy all kinds requirement of mobile data service from their client, and provide support to client service at any time and any place.Based on the trend of wireless telecommunication market of recent years, value added service has become the new rise of economic of wireless telecommunication. With the open of the domestic market of value added service of telecommunication, and it being easy to enter this area, many equipment provider, operator and Service Provider (SP) national or international has good expedition on it and join this market one after another, and the competition has become more and more intensive, so the construction of PCSS based on USSD is of important practicability.
