- the detecting the resource usage status of the current eNB is generally detected multiple times, and may be real-time detection or periodic detection.
- the detecting that the resource usage status of the current eNB meets the alarm condition includes: initially detecting that the resource usage rate of the current eNB exceeds a first preset threshold, or initially detecting that the resource usage rate of the current eNB is lower than a second preset threshold. Or detecting that the resource usage status information in the current eNB is inconsistent with the resource usage status information of the current eNB that is detected last time, and detecting that the resource usage status of the current eNB exceeds a first preset threshold, or detecting the current eNB. The resource usage status is lower than the second preset threshold.
- the first preset threshold and the second preset threshold may be set according to requirements in an actual application.
- the first preset threshold is a threshold for determining that the resource usage rate is high. When the actual resource usage rate exceeds the first preset threshold, the resource usage rate of the current eNB is considered to be high, and the alarm condition is met, for example, when When the resource usage rate of the eNB exceeds 80%, the alarm condition is considered to be reached;
- the second preset threshold is a threshold for determining that the resource usage rate is low, and when the actual resource usage rate is lower than the second preset threshold, the current eNB is considered as the current eNB.
- the resource usage rate is low, and the alarm condition is met. For example, when the resource usage rate of the current eNB is less than 20%, the alarm condition is considered to be reached.
- the first preset threshold should be no less than a second preset threshold.
- the neighboring eNB may determine the location and interaction relationship of the other eNBs in the actual application in the actual application, and may be one or multiple.

- the resource usage status of the current eNB changes, for example, the resource usage status is detected as the resource usage rate is high, and the resource usage status detected this time is low, the resource usage status information is transmitted to the eNB again.
- the resource usage status is detected to be in the resource usage high/low state last time, and the detected resource usage status is still the resource usage rate high/low state, it indicates that the neighboring two detection resource usage states do not occur.
