[0002] Satellite mobile communication systems can transmit information in a timely, accurate and effective manner, and can cover areas that are difficult to reach with other ground communication methods, such as vast oceans and deserts, and can be used in remote areas. Satellite mobile communications are less affected by natural and environmental factors, have better channel conditions, and have relatively stable communication quality.

[0003] The Tiantong industry application system consists of front-end applications (including Tiantong terminals), Tiantong satellite mobile operation network, Tiantong access system, user application system and other parts. Among them, the Tiantong satellite mobile operation network is built by China Telecom and has been put into operation. It does not require construction by users in various industries. It only needs to forward the front-end application to the user's related application system through the Tiantong system. However, due to the wide variety of services involved in the system, it is not possible to simply access the user application system, and access translation is required. The access translation process involves Tiantong satellite mobile communication technology, which industry users cannot grasp in time. Therefore, it is necessary to design a universal Tiantong access platform so that users can realize the access of various terminal information and services to the user application system without feeling, and complete terminal management and business presentation.
