Description

Channel management method, device, equipment, system and storage medium

Technical Field

Background

In an existing gigabit passive Optical Network G/EPON management model, internet service configuration for Optical Network Units (ONUs) is mainly in a Point-To-Point (P2P, point To Point) manner, that is, wireless parameters are configured for each ONU individually. Because the number of the networked intelligent devices is increased, on one hand, the efficiency of configuring wireless parameters in a P2P mode is low; on the other hand, the number of wireless routing devices accessing the channel is increased, and the congestion degree of the channel is increased.

The channel transmission speed may be affected by a complex environment of a surrounding Wireless network (WIFI), and if a channel where a user uses a WIFI signal overlaps with a channel of a surrounding WIFI signal, the channel may be interfered, and therefore, the Wireless routing device needs to switch channels frequently. However, the existing channel switching method usually directly selects the best channel of the current signal and then switches, but the congestion situation of the signal changes very rapidly, if the channel with the best quality is directly selected each time, the channel switching is quite frequent, and the service life of the routing device is reduced.

In an environment of Fiber To The Room (FTTR), a plurality of ONUs enter a user home, and high bandwidth and large capacity support capability of a Fiber channel is brought while satisfying The current mainstream home entertainment and interconnection requirements. However, wireless management is performed on a plurality of ONUs in batches, so that the Network speed and stability of a Wireless Local Area Network (WLAN) for surfing the internet are improved, the Wireless configuration process of the ONUs is simplified, the coordination and interconnection requirements required by the ONUs are met, and an effective solution is not available at present based on a traditional management means.
