CROSSTALK CANCELLATION METHOD, APPARATUS AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/077991

Kind Code:

A1

Abstract:

Embodiments of the present invention provide a crosstalk cancellation method, apparatus and system. The crosstalk cancellation method of the present invention comprises: when the number of online customer premises equipments (CPEs) is to change, determining the type of the online CPEs before change and predicting the type of online CPEs after change, wherein the type of the CPEs refers to that the online CPEs are all nonlinear CPEs or a mixture of nonlinear CPEs and linear CPEs, a linear CPE is a CPE supporting only linear crosstalk cancellation on a line connected to the CPE, and a nonlinear CPE is a CPE supporting both linear crosstalk cancellation and nonlinear crosstalk cancellation on a line connected to the CPE; and if the determined type of the online CPEs before change is inconsistent with the predicted type of the online CPEs after change, sending handover instruction information to the online CPEs before change according to a crosstalk cancellation mode supported by the predicted type of the online CPEs after change. The embodiments of the present invention solve the problem that CPEs of different modes cannot get online at the same time, and improve communication performance.
