Elastic beam position resource scheduling system and scheduling method for jump beams

Abstract

The invention provides an elastic beam position resource scheduling system and scheduling method for jump beams. A beam position refers to a coverage area of a jump beam on the earth surface on a specific direction, and the availability is subject to the allocation of time slots. The elastic beam position resource scheduling system comprises: a resource manager, a processor, a beam controller, a transmitting antenna and a receiving antenna, the resource manager completes an elastic beam position resource scheduling process according to service access request signaling and sends an instructionto the receiving antenna and the beam controller in the sending antenna so as to control the jump timing sequence of the jump beam, and sends scheduling information to the processor to ensure the synchronous cooperation of the transmitted data and the beam position. The elastic beam position resource scheduling method, that is, a processing and control operation flow of the resource manager, mainly comprises determining an elastic beam position, resource optimization distribution and the jump control. Based on the high dynamics of the user demand distribution and the shaping variability of thejump beam, the utilization ratio of jump beam resources and the flexible anti-interference capability can be effectively improved.

Description

technical field [0001] The invention relates to a flexible scheduling system and scheduling method for wave position resources oriented to hopping beams, and belongs to the field of satellite communication resource management. Background technique [0002] The use of beam-hopping technology can meet the high-gain coverage requirements of any point in the field of view, and has become a necessary configuration for satellite communication systems to support dynamic distribution of service terminals in large areas, flexible communication, and improve system anti-interference capabilities. In view of the fact that the beam resource of beam hopping is closely related to the location distribution of users, it is of great significance to study the scheduling mechanism of beam resource oriented to beam hopping. [0003] In the case of limited system frequency band resources and limited on-board processing resources, phased array beam-hopping can solve regional communication problems...
