Abstract

The invention provides a processing method and a CCo in a power line communication network. The method includes that the CCo detects the state of the PCo, and the state of the PCo includes: the PCo is normal or the PCo is offline; after determining that the PCo is offline, the CCo designates a new PCo for the hidden station corresponding to the offline PCo. The embodiment of the present invention can try to ensure that the service of the hidden site is not interrupted after the PCo is offline.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a processing method and a central coordinator (Central Coordinator, CCo) in a power line communication network. Background technique [0002] Power line communication (Power Line Communication, PLC) is to load high-frequency signals carrying information onto the power line, and use the power line for data transmission. The home broadband PLC network is a PLC-based network. There is a CCo in each home broadband PLC logic network. The central coordinator can manage the entire network, such as coordinating the transmission of sites in the network and authenticating new sites that join the network. , manage encryption keys, and coordinate resource sharing with adjacent networks. In a home broadband PLC logical network, due to channel conditions or other factors, some stations may not be able to detect messages such as beacons sent by the CCo, that is, there are ...
