TECHNICAL FIELD

[0002] Satellite communication technology has the characteristics of long communication distance, wide service coverage, high system transmission reliability and not easy to be affected by the ground environment, and is widely used in various industries. With the more and more extensive application of satellite communication technology, large satellite communication constellations have begun to be popularized, and various types of communication satellites such as medium-low orbit, inclined orbit, and near-polar orbit have also begun to be more widely used. The corresponding satellite communication system and communication network topology are more diverse. In mission support applications, there is an increasing demand for various hybrid heterogeneous networks to form an integrated mission support communication network, and the network scale is becoming larger and larger. Therefore, the demand for multi-network rapid networking, high-quality communication task support, network interconnection, and unified management of large-scale hybrid heterogeneous networks is increasing. In order to improve the networking speed, task support quality, and multi-network integrated management and interconnection management capabilities of hybrid heterogeneous networks, a system and method capable of unified planning and management of multi-satellite joint support and multi-type hybrid heterogeneous networks are needed to improve the integrated management capabilities and support efficiency of satellite communication systems.

[0003] The satellite communication integrated management system not only includes communication network planning of multiple systems and multiple network topologies according to the task support requirements from users to realize rapid and high-quality networking, but also includes management of the interconnection relationship and strategy between various networks and health state management of the various networks. In addition, the system can also implement integrated centralized management and hierarchical and regional management of the various networks.

Moreover, traditional multiple task networks are independent of each other and isolated from each other, which cannot realize the interconnection between multiple system and multiple structure networks, seriously restricting the unified management and collaborative task support capabilities of satellite communication networks.
