Problems solved by technology

In the staring mode, due to the movement of the source satellite, there is no way to continue to provide services for the staring area in the staring mode. The target satellite needs to continue to provide services to the terminal equipment in the staring area of ​​the source satellite. At this time, the staring area of ​​the source satellite All terminal devices in the network must be switched to the target satellite, which will generate signaling storms and cause network congestion, thereby affecting communication performance

Embodiment Construction

[0063] The technical solution of the application can be applied to a satellite communication system. see figure 1 , figure 1 It is a schematic diagram of the architecture of the satellite communication system. The satellite communication system 100 generally consists of three parts: space segment, ground segment and user segment. The space segment may be composed of geostationary earth orbit (geostationary earth orbit, GEO) satellites, non-geostationary earth orbit (none-geostationary earth orbit, NGEO) satellites, or a multi-satellite network 101 composed of both. The ground segment generally includes a satellite measurement and control center 102, a network control center (NCC) 103, and various gateway stations (gateway) 104, etc., which are also called gateway stations. Wherein, the network control center is also called a system control center (system control center, SCC). The user segment consists of various terminal equipment. The terminal equipment may be various mo...

Abstract

The present application provides a method and device for switching. The method includes: determining some terminal devices that will be switched among multiple terminal devices in the staring area of ​​the first beam; sending a first switching request message to the target satellite, where the first switching request message includes the context of some terminal devices; receiving the target The satellite sends the switching instruction to some terminal devices through the first beam according to the switching instruction sent by the first switching request message, and the switching instruction includes switching parameters for some terminal devices to perform switching. The method can switch some of the multiple terminal devices in the staring area, can avoid the problem of signaling storm, and helps to improve communication performance.

Description

technical field [0001] The present application relates to the field of satellite communication, and more particularly, to a method and a switching device for handover in the field of satellite communication. Background technique [0002] In some important fields, satellites play an irreplaceable role, such as space communication, aviation communication, maritime communication, military communication, etc. Satellite communication has the advantages of long communication distance, large coverage area, and flexible networking. Satellites can provide services for both fixed terminal equipment and mobile terminals. [0003] In satellite communications, satellites can be divided into geostationary orbit satellite systems and non-geostationary orbit satellite systems according to the height of the orbit where the satellite is located. Among them, non-geostationary orbit satellite systems can be divided into medium-orbit satellite systems and low-orbit satellite systems. The low-or...
