Mobile Network Architecture

The Mobile Network Architecture (MNA) is designed to provide a cohesive, consistent framework for the development of a new generation of mobile data communications systems. This new generation of systems is required to meet the varying needs of current and future users, providing integrated support for the development, attachment and operation of diverse mobile applications. This paper describes the form and function of the three component architectures of the MNA, and how these components provide service to the users of an integrated mobile data network. The Communications Architecture, which is based upon the CCITT Open Systems Interconnection reference model, supports a layering of communications services and protocols for mobile data transport. The Operations, Administration and Maintenance Architecture, which is derived from the ISO OSI Management Framework, facilitates centralized management and control of a mobile network. Finally, the Applications Architecture, which uses a transaction-based model derived from experience with existing mobile applications, supports user applications in the harsh mobile environment.
