Design And Implementation Of Key Technologies Of Authentication Subsystem Of Open Mobile Platform

With the advent of the mobile Internet, in order to extend the advantages already existing on the Internet, integrate system resources, and improve user adhesion, open platform concept was first proposed by the Internet giant. At present, both domestic and foreign Internet companies are urged to build their own open platform, in order to seize the initiative in this technology wave. In this condition, any evasive action on the openness of the Internet and the developer community building are short-sighted. Meanwhile, in order to avoid gradually becoming a data pipe, traditional telecom operators also begin to try to launch their own open platform to face the upcoming crisis and challenges.OMP (Open Mobile Platform) is an open platform designed by China Mobile Communications Corporation in order to meet the needs of mobile Internet business. It is an open, standards-based integrated platform for the integration of Internet and telecommunications infrastructure, providing OpenAPI and also acting as an operation and management platform. For third-party developers, it provides a complete application publishing and running environment; for ordinary users it supports applications mall where applications can be purchased conveniently; for mobile operators, it has comprehensive operation and management functions. OMP is essentially a additional network facility and a running engine to support the running of mobile Internet applications bounding specific capacities based on the telecommunications network. And it involves key technologies such as the design and implementation of OpenAPI as well as the ability of operation, safety certification and charging.As a running engine of an integrative platform of the telecommunication network and Internet business, the network architecture and open technology of OMP are unique. This article focuses on authentication subsystem (AUS), elaborating on AUS architecture, services management module, and then analyzing the key technologies involving the design and implementation of this program. The first chapter describes the development of open platform both domestic and international, and thus leads to the concept of the telecommunications open platform and OMP. The second chapter describes the the authentication subsystem architecture, the protocol interfaces, function modules, and a few basic services. Chapter III analyses several key technical solutions while designing AUS:solution to ensure system’s high availability (load balancing, overload control, etc.), security authentication mechanism (in the terminal environment), design of service expansion while adding In-App Purchase capacity. In Chapter4we first do AUS performance testing and analysis of the current performance bottlenecks; then we do time-delay testing of the whole OMP platform, analysis of the statistics of the time delay between each module. Chapter five states some legacy issues, pointing the direction for the next phase of work.The research on open the platform is still a relatively new topic. Though the design and realization of the OMP has completed and the testing and operation result of the platform basically meet the current needs, with the development of service, there still exists huge space to further enhance.
