A Resource Management Method Based on Satellite-Ground Cooperative Processing

Abstract

The present invention provides a resource management method based on satellite-ground collaborative processing, including the following steps: S1. Randomly generate an initial resource allocation scheme corresponding to a beam, so as to randomly allocate part of user services covered by the beam to on-star processing and remaining users The business is allocated to the ground processing, and the initial comprehensive optimization target value is calculated; S2, the initial resource allocation plan is pre-adjusted for multiple rounds until the preset adjustment stop condition is met, and the resource allocation plan corresponding to the minimum comprehensive optimization target value is retained; S3, according to The final resource allocation scheme allocates all user services under the current beam coverage to on-board processing or ground processing, and adjusts the power configuration of user links and feeder links. The present invention integrates the distribution of service types under beam coverage, service QoS guarantee requirements, and user channel quality, etc., performs satellite-ground collaborative processing and allocation of services under beam coverage, and maximizes the use of network resources to obtain the minimum average delay and maximum throughput. quantity.

Description

Technical field [0001] The present invention relates to wireless communications technology, particularly, relates to dynamic radio resource management technique in the field of wireless communications, and more particularly, to a multi-beam satellite in a satellite communication network to co-resource management method. Background technique [0002] Limited current carrying capacity of the satellite system, the communication load to use more elbow-type transparent transponder payload, and the fixed resource allocation method is simple and easy to achieve in resource management. Fixed resource allocation method lacks flexibility in the allocation of resources capacity, can not effectively respond to business changes in the beam coverage, resulting in inefficient use of resources in the resource manager. In addition, due to the high orbit far from the ground, satellite transmission delay service network is usually relatively large, to protect the user QoS problems faced. Based on t...

Problems solved by technology

However, the role of these technologies in improving the utilization of wireless resources, such as improving beam throughput and reducing packet loss rate and other key performance indicators, has not been further explored, and on-board resources including computing resources, storage resources, and on-board feeder resources have been ignored. When the wireless resources of the power and user links are jointly allocated, it can reduce the delay and improve the beam throughput.
