Beam-hopping satellite cross-beam-position resource allocation method

Abstract

The invention provides a cross-beam-position resource allocation method for a beam-hopping satellite, which is used for solving the problem of resource allocation when a user terminal moves across a beam position in a satellite beam-hopping scene. The basic idea of the method is that when a user terminal moves to the coverage range of another beam position from one beam position, a satellite control module determines the resources of the mobile terminal according to the beam jump of a source beam position and a target beam position; wherein the principle of resource allocation is to provide non-inductive cross-beam service for the mobile terminal on the premise of not influencing the existing online user terminal. According to the method, a resource allocation scheme during terminal beam crossing is designed for a satellite beam-hopping scene, the implementation principle is simple, the operability is high, and the reliability is relatively high. The method can be applied to a related hopping beam satellite communication system, and has guiding significance for the design of a satellite load.

Description

technical field [0001] The invention relates to a cross-beam resource allocation method for a beam-hopping satellite, belongs to the technical field of beam-hopping, and studies the resource allocation method under cross-beam. Background technique [0002] The combination of satellite and beam hopping is a new technology. Through the investigation of related technologies, the resource allocation schemes in the following two cases are summarized. [0003] (1) Resource allocation scheme for satellite fixed beam coverage [0004] Many satellite systems in our country have the ability to allocate resources independently on the satellite. Due to the fixed beam coverage of the satellite, when the terminal is moving, the target area will have beam coverage. When the terminal crosses the beam, it only needs to allocate resources at the target wave position through the satellite to ensure continuous service. [0005] Due to the characteristic of beam hopping covering specified wav...

Problems solved by technology

[0010] The technical problem solved by the present invention is to provide a cross-beam resource allocation method for beam-hopping satellites according to the beam-hopping characteristics of beam-hopping. According to whether the source wave position and target wave position have beam-hopping services, the service mode is distinguished, which not only ensures In order to ensure that the services of the existing terminals on the network are not affected, and try to keep the resources of the mobile terminals unchanged, only when the two cannot be satisfied, then re-allocate new beam-hopping resources for them, which improves resource utilization and simplifies Terminal operation steps
