Hopping beam satellite system workflow and signaling frame design method for controlling associated service

Abstract

The invention discloses a hopping beam satellite system workflow and signaling frame design method for controlling an associated service, which comprises the following steps that: 1, a system controlsignaling is sent through a service beam, and user synchronization, network access, hopping beam resource application and other operations are completed through wave position polling when a certain service demand area is served for the first time; 2, a network control center establishes an objective function oriented to resource global scheduling and flexible allocation; 3, the target function inthe step 2 is solved; 4, a wave beam hopping period and a wave beam residence time parameter are set, and a hopping wave beam time schedule is generated by utilizing the time slot number of the wave beam; 5, the framing of the BHTP signaling frame is completed; 6, the satellite and the user demodulate the BHTP signaling to complete satellite-ground integrated beam synchronous hopping; and 7, the user performs service transmission and completes service application of the next hop beam period. According to the invention, an independently configured control beam is not needed, extra overhead caused by re-synchronization of a user in a beam hopping period is avoided, and the utilization rate of system time slot resources is improved.

Description

technical field [0001] The invention proposes a work flow design scheme of a satellite communication system based on beam hopping, which belongs to the field of satellite communication. It mainly involves the workflow in the scenario where the control signaling follows the service beam in the beam hopping satellite, and the optimal design of the beam hopping rule and the beam hopping time plan (BHTP) signaling frame structure in this process. Background technique [0002] Communication satellites can increase capacity by increasing the number of spot beams. However, the traditional multi-beam satellite method of allocating fixed resources to each beam results in a waste of system resources due to the limitation of allocating available resources within a single beam and the unevenness of user service requirements. , limiting the increase in system throughput. In recent years, the research work on the theory and technology of beam hopping shows that beam hopping technology ca...

[0004] The purpose of the present invention is to propose a beam-hopping satellite system work flow that controls the beam-hopping satellite system that follows the service and the process under the flow in view of the problem that the satellite load and the amount of terminal equipment are large in the existing interactive mode in which the control of the beam-hopping system is separated from the business. The BHTP signaling design method reduces the amount of equipment in the beam-hopping satellite system, avoids the additional overhead caused by re-synchronization of users during the beam-hopping period, improves the utilization of system time slot resources, and meets user business service needs
