Problems solved by technology
However, the linear velocity of low-orbit satellites relative to the ground is also relatively large. Generally, the low-orbit satellites connected to user equipment will not be able to cover the currently connected user equipment 10 to 20 minutes after the connection is established. In order to maintain the continuity of communication , it is necessary to switch the service of the user equipment from the current low-orbit satellite to a low-orbit satellite that can cover the user equipment for a period of time
The current related technology is to perform handover directly. In this way, when multiple user equipments are handed over, a large number of handovers will be performed concurrently in a short period of time, which will bring a lot of signaling overhead, which will affect the performance of the communication satellite before and after the handover, and even cause communications satellite crash

Embodiment Construction
[0055] In this embodiment, the application scenario of the communication satellite switching method is as follows figure 1 shown. refer to figure 1 On the left side, in the first time period, the first communication satellite sat1 covers a plurality of user equipments including user equipment A, and the first communication satellite sat1 is connected to some or all of the user equipments, and communicates with all of them. The connected user equipment provides communication services. refer to figure 1 The right side of , enters the second time period after the first time period ends, and multiple user equipments including user equipment A move relatively slowly or are stationary relative to the ground. Therefore, multiple users including user equipment A can move The device is considered to be still within the coverage area of the first communication satellite sat1 in the first time period. Due to the relative ground motion of the first communication satellite sat1, the f...

The invention discloses a communication satellite switching method, a space-ground integrated information network system, a computer device and a storage medium. The communication satellite switching method includes obtaining the access time of each user equipment and the characteristic services provided by the first communication satellite to each user equipment Type, determine the third weight according to the access time of the user equipment and the characteristic service type, determine the switching sequence of each user equipment according to the third weight, switch the connection of each user equipment from the first communication satellite to the second communication satellite, etc. . The present invention can allocate multiple user equipments to different moments in a time period for switching in the case of batch switching of multiple user equipments, so as to prevent multiple user equipments from accessing the second communication satellite at the same time and causing damage to the second communication satellite. impact, improve the working stability of communication satellites, and can comprehensively consider the influence of user equipment access time and business type, and improve business stability. The invention is widely used in the field of communication network technology.
Description
technical field [0001] The invention relates to the technical field of communication networks, in particular to a communication satellite switching method, a space-ground integrated information network system, a computer device and a storage medium. Background technique [0002] The communication satellite switching method composed of a space-based satellite network and a ground-based core network can integrate the advantages of large ground communication capacity, low delay, high performance, and wide coverage of satellite communication. Since the low-orbit satellites are close to the ground and the communication delay with the user equipment is low, the user equipment is generally connected to the low-orbit satellites when connecting to the satellite network. However, the linear velocity of low-orbit satellites relative to the ground is also relatively large. Generally, low-orbit satellites connected to user equipment will not be able to cover the currently connected user ...
