METHOD AND SYSTEM FOR INTERFERENCE DETECTION AND MITIGATION

摘要

In a method for adjusting the modulation of information onto subcarriers transmitted on a network, a first modulation profile of a network node on the network is set a first density. A plurality of messages in support of a link maintenance operation (LMO) on the network are monitored. The first modulation profile of the network node is updated to a second modulation profile having a second density. The updating is based on the monitored messages. Interference is detected by determining that a link between the first network node and a second network node on the network is not conveying a predetermined class of messages correctly. The first network node is set to a third modulation profile more robust than the first and second modulation profiles in response to the detected interference. The third modulation profile is common to each network node on the network.

1. A method for adjusting modulation on a network, the method comprising;
determining that at least one of a probe request or probe report has been transmitted during a link maintenance operation (LMO) between an LMO node and a network node; detecting interference on a link between the LMO node and a network coordinator (NC) or on a link between the network node and the NC that interferes with the reception of the transmitted probe request or probe report; and in response to the detected interference, the NC sending a message to the LMO node or to the network node that instructs the LMO node or the network node to adopt a robust modulation profile for transmissions to the NC.
