Satellite communication system based on communication traffic prediction and wireless resource dynamic allocation

Abstract

The invention relates to a satellite communication system based on communication traffic prediction and wireless resource dynamic allocation. The system comprises a CS and PS service request module which is used for collecting and accumulating corresponding service communication traffic in a period of history time window; a CS and PS prediction module which is used for setting a prediction model for the corresponding service communication traffic, receiving the communication traffic and providing a prediction value for the corresponding service communication traffic in a period of future time window; a service communication traffic analysis module which is used for carrying out summarizing operation on the prediction value, thereby at least obtaining a proportion relationship for the service communication traffic and the total communication traffic; a wireless resource allocation strategy module which is used for setting a wireless resource allocation strategy; a wireless resource coordination module which is used for adjusting a wireless resource allocation proportion for the service communication traffic according to the allocation strategy; and a wireless resource allocation module which is used for carrying out proportional allocation on the satellite wireless resources. The system has the beneficial effects that through dynamical adjustment of the service resource allocation share proportion, the integrated utilization efficiency of the satellite wireless resources is improved, moreover, the fairness is ensured, and the normal operation of other service is ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a satellite communication system based on communication traffic prediction and wireless resource dynamic allocation. Background technique [0002] At present, the satellite communication system mainly adopts CS domain (circuit switching) or PS domain (packet switching). The CS domain is circuit-oriented and can carry transmission services of various bandwidths; the PS domain is represented by satellite broadband communication systems, and its operating services are mainly IP data packets. For example, the International Maritime Satellite System (Inmarsat), Thuraya Satellite System (Thuraya), Asian Cellular Satellite System (ACeS), and Globalstar System (Globalstar) mainly use circuit switching to provide narrowband services such as voice, fax, and SMS; and Broadband satellite systems such as IPSTAR broadband satellite system, AmerHis satellite communication system, and WIN...
