Agile spot beam bidirectional collaborative polling method for satellite signaling

Abstract

The invention discloses an agile spot beam bidirectional collaborative polling method for satellite signaling, which comprises the following steps that: 1, a ground station sends a forward backward beam hopping pattern to a satellite through a load service management and control channel, a hopping beam controller of the satellite demodulates a forward backward hopping beam control instruction pattern, and the forward backward hopping beam control instruction pattern is sent to the ground station; the wave beam jumps according to the instruction; 2, a forward beam polls each beam position on the ground in sequence to provide broadcast signaling, when the beam position where the user terminal is located receives the forward beam, one or more beam frame durations are fixedly delayed, a backward beam is scheduled to poll the beam position, and backward signaling data are transmitted; and 3, under the condition that the numbers of the forward and backward beams are not equal, optimal matching of forward and backward beam resources is achieved through cross polling of each beam position. According to the method, the forward wave beam and the backward wave beam of the satellite can be set as wave beams which can flexibly jump, so that satellite resources can be utilized in a collaborative and efficient manner.

Description

Technical field [0001] The present invention relates to the field of satellite communication, and more particularly to a bidirectional coordination of satellite signaling. Background technique [0002] With the development of satellite network, the application based on satellite network is increasingly common. Satellite networks are an important supplement to the ground network, which can provide Internet access, emergency communication, etc. In a conventional multi-beam satellite communication system, the surface user is generally served in a fixed beam. For example, in HTS (High Throughsatellite, high-through-satellite) system, the pointing and coverage of satellite beams are fixed, generally assigned to each beam power, and time-frequency resources are constant. However, in the satellite communication system, different users have a variety of communication service types and business requirements, space-space distribution, different regions, users of different regions, differen...

Problems solved by technology

However, in the use of agile beams, the existing technology cannot give full play to the efficiency of the beams, and the system interaction is complicated and not concise.

At the same time, under normal circumstances, the number of satellite forward beams and return beams is not equal, and the existing technology cannot make forward / return coordination achieve optimal system performance
