Problems solved by technology

[0017] The inventor found in the process of researching the prior art that although maximizing the line rate can meet the user's requirements for the rate, with the emergence of services such as VOIP services and IPTV services that require higher line quality, only the line rate can be satisfied. The requirements may cause line quality degradation, such as voice delay and picture frame loss, etc. Due to the unstable line operation quality, the user experience is reduced; and since users do not need a high rate in most cases, the maximum line rate is used. The way will waste the power in the system, increase the crosstalk between the lines, and increase the cost of the system

Embodiment Construction

[0042]Embodiments of the present invention provide a DSL-based power optimization method, system, and equipment, which collect user service information, obtain physical layer target parameters according to QoE parameters corresponding to each service information, and receive line operation information of the user. The line operation information includes test parameters and pre-stored line target parameters, and the physical layer target parameters and the line operation information are used as input parameters of a power optimization algorithm to obtain an optimized power spectrum through the power optimization algorithm.

[0043] In DSL technology, it is difficult to optimize and improve the DSL network conditions by obtaining the maximum rate, that is, it is difficult to improve performance indicators such as bit error rate and dropped call rate, so customer experience is not high. In order to improve the customer's QoE, the embodiment of the present invention optimizes the D...

Abstract

The invention discloses a power optimization method, system and device based on digital user line. The method comprises: collecting user business information, obtaining physical layer target parameter according to QoE parameter corresponding to information of every business, receiving user line operation information which includes test parameter and pre-stored line target parameter, obtaining optimized power spectrum by power optimization algorithm using physical layer target parameter and the line operation information as power optimization algorithm parameter. In the invention DSL network is optimized according to QoE, user experience is promoted, emission power spectrum is optimized adopting minimum power method, total power consumption is reduced simultaneously QoE is satisfied, crosstalk between different DSL signal is reduced and so system signal transmission is stable and transmission quality is promoted.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a DSL (Digital Subscriber Line, Digital Subscriber Line)-based power optimization method, system and equipment. Background technique [0002] DSL technology is a technology for high-speed data transmission through UTP (Unshielded Twist Pair, unshielded twisted pair), including ADSL (Asymmetrical Digital Subscriber Line, Asymmetrical Digital Subscriber Line), VDSL (Very-high-bit-rate Digital Subscriber Line , Very High Speed ​​Digital Subscriber Line), IDSL (Integrated Services Digital Network Digital Subscriber Line, user digital line based on integrated services digital network) and SHDSL (Single-pair High-bit-rate Digital Subscriber Line, single-pair High-bit-rate Digital Subscriber Line), etc. . [0003] Among various DSL technologies, except IDSL and SHDSL and other DSLs that transmit services through baseband, other DSLs usually use passband to transmit servi...
