Abstract

The invention discloses a high-throughput satellite terminal beam switching method and device based on a 5G core network. The method comprises the following steps: periodically receiving position information reported by a satellite terminal through a network management system, judging whether the satellite terminal needs to carry out beam switching or not according to the position information, if so, notifying a target network control center to carry out resource preparation, notifying a source Internet gateway to carry out a switching preparation start command; meanwhile, satellite network data in the target internet gateway are sent; after the switching preparation work is completed and the network management system receives a switching start confirmation message sent by the source internet gateway, the satellite terminal is notified to log in a specified target beam in a mode that a source network control center sends a unicast satellite terminal information message; and after the satellite terminal completes beam switching, the target network control center notifies the target Internet gateway that switching is completed through the network management system. According to the invention, beam switching and exception handling of the satellite terminal can be successfully completed.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method and device for switching beams of high-throughput satellite terminals based on a 5G core network. Background technique [0002] At present, satellite communication has the characteristics of wide coverage, wide frequency band, large capacity, and flexibility, and is an ideal solution. However, the coverage of a single satellite is limited, and the capacity cannot support communication needs, so it is necessary to combine satellites in different regions. These satellites form partially overlapping communication beams on the ground, so they must face the problem of beam switching. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the deficiencies of the prior art and provide a high-throughput satellite terminal beam switching method and device based on the 5G core network. [0004] Technical solution...
