METHOD, SYSTEM AND DEVICE FOR POWER OPTIMIZATION BASED ON DIGITAL SUBSCRIBER LINE

摘要

A method, system, and device for power optimization based on Digital Subscriber Line (DSL) are provided. The method includes the following steps. Service information of a subscriber is collected, and physical layer target parameters are obtained according to Quality of Experience (QoE) parameters corresponding to the service information. Line running information of the subscriber is received. The physical layer target parameters and the line running information are used as input parameters of a power optimization algorithm, and an optimized power spectrum is obtained through the power optimization algorithm. Therefore, a DSL network is optimized according to the QoE, and subscriber's experience is improved. Moreover, a least power method is adopted to optimize a transmit power spectrum, and the total power consumption and crosstalk between different DSL signals are reduced while meeting the QoE, so that the signal transmission of the system is stable, and the service transmission quality is improved.
