base stations

102 and 103 respectively allocated to the

base stations

A channel indication message, wherein the channel indication message includes a second radio channel resource.

In the embodiment of the present application, the triggering event may be, for example, that the central management device 101 receives the reported channel scan result from the

base station

For example, the triggering event is that the base station 102 reports the channel scan result, and when receiving the channel scan result reported by the base station 102, the central management device 101 triggers the central management device 101 to obtain the channel scan result of the predetermined time range, and then the central management device 101 is based on the preset. The channel scan result of the time range determines whether the first radio channel resource f1 allocated to the base station 102 in advance has interference and the type of interference exists. The preset time range may be the channel scan result reported by the base station 102 in the past 24 hours. The specific time limit is only used to better understand the present application, and is not limited thereto.

For another example, the triggering event may be, for example, that the central management device 101 receives the electronic tag request instruction of the external application system for the electronic tags 105-1, 105-2, 105-3, and 105-4, and triggers the central management device 101 to acquire the channel scan result of the predetermined time range, and then The central management device 101 determines whether the first wireless channel resource f ₂ allocated to the base station 103 in advance has interference and the type of interference based on the channel scan result of the preset time range. The preset time range may be the channel scan result reported by the base station 103 within 4 hours before the trigger event is received. The specific time limit is only used to better understand the present application, and is not limited thereto.

The processor of the central management device 101 determines the interference type of the first radio channel resource based on the obtained channel scan result of the preset time range, and then generates a channel indication message according to the interference type, and includes the second radio channel resource in the channel indication message.

base station

102, 103 broadcasts the foregoing channel indication message to the electronic tags 104-1, 104-2, 104-3, 104-4, 105-1, 105-2, 105-3, 105-4. The electronic tag that receives the channel indication message establishes communication with the second radio channel resource carried by the channel indication message between the base station, and after the completion of the process, carries the usage indication to modify or release the radio resource according to the channel indication message.
