Title:
POWER ADJUSTING METHOD, NETWORK MANAGEMENT SYSTEM, CABLE MODEM TERMINAL SYSTEM AND CABLE MODEM
Document Type and Number:
WIPO Patent Application WO/2018/023701
Kind Code:
A1
Abstract:
Provided in the present invention are a power adjusting method, a network management system, a CMTS and CMs. The power adjusting method comprises: a network management system obtaining a first SNRCM which is between two CMs and which is connected with a CMTS, the first SNRCM representing a signal ratio between a signal which is received by a first CM and which is sent by the CMTS to the first CM and a signal which is received by the first CM and which is sent by a second CM to the CMTS; the network management system, according to the first SNRCM as well as a first relation between an SNRCM and a transmitting power used by the CMTS to send signals to the first CM, sending instruction information to the CMTS, wherein the instruction information is used to instruct the CMTS to adjust the transmitting power used by the CMTS to send signals to the first CM, so that the SNRCM corresponding to the adjusted transmission power is a target value of a same frequency mutual interference signal-to-noise ratio between the two CMs. Provided in the present invention are a power adjusting method, a network management system, a CMTS and CMs, capable of adjusting the power of the CMTS according to a same frequency interference signal-to-noise ratio between the CMs and the relationship between the same frequency mutual interference and the power, so as to be able to flexibly change the same frequency interference signal-to-noise ratio between the CMs, and flexibly group the CMs.
