It should be noted that, in this embodiment of the present disclosure, reference may be made to the process of detecting the interference condition of the carrier signal in the next data acquisition period by the terminal device in step S405, and details of this process are not described herein.
Step S408, if the total interference index values are smaller than the total interference index value threshold and the statistical signal interference period is larger than the third threshold, determining whether the total interference index value of the previous data acquisition period is smaller than the total interference index value threshold.
In the embodiment of the present disclosure, the third threshold is a critical value for determining whether there is an interfered data acquisition period of the carrier signal, and the third threshold is determined based on actual needs, which is not limited in the embodiment of the present disclosure. For example, the third threshold may be 0.
In an optional embodiment, if the terminal device determines that the total interference index value of the current data acquisition period is smaller than the total interference index value threshold, it is determined that the carrier signal is not interfered in the current data acquisition period; and if the terminal equipment determines that the signal interference period statistic is larger than the third threshold, it can be determined that the interfered data acquisition period exists in the carrier signal when the current data acquisition period is cut off in the interference detection process of the carrier signal. Further, the terminal device may determine whether the total value of the interference index of the previous data acquisition period is smaller than the total value threshold of the interference index, so that the terminal device determines whether the carrier signal has an undisturbed condition of consecutive data acquisition periods, and further determines whether the interference of the carrier signal is eliminated.
In an optional implementation manner, if the terminal device determines that the total interference index value is smaller than the total interference index value threshold, it is determined that the carrier signal is not interfered in the current data acquisition period; if the terminal device determines that the signal interference period statistic is smaller than or equal to the third threshold, it can be determined that the current data acquisition period is cut off and the interfered data acquisition period does not exist in the carrier signal in the interference detection process of the carrier signal; whether the current data acquisition period is the last data acquisition period corresponding to the carrier signal can be further judged, if the current data acquisition period is the last data acquisition period corresponding to the carrier signal, it can be determined that the carrier signal is not interfered in the interference detection process of the carrier signal, and the interference detection process of the carrier signal is finished; and if the current data acquisition period is not the last data acquisition period corresponding to the carrier signal, detecting the interference condition of the carrier signal of the next data acquisition period.
Step S409, if it is determined that the total interference index value of the previous data acquisition period is smaller than the threshold of the total interference index value, updating the statistics of the signal interference cancellation period.
In the embodiment of the present disclosure, the signal interference cancellation period statistic is used to indicate the number of consecutive undisturbed data acquisition periods corresponding to the carrier signal after the carrier signal is interfered.
In step S409, the process of updating the signal interference cancellation period statistic by the terminal device may include: and determining the sum of the signal interference elimination period statistic value of the carrier signal and a second reference value to obtain an updated signal interference elimination period statistic value, wherein the second reference value is 1. It is to be understood that the second reference value of 1 is used to indicate that the carrier signal is not interfered during the current data acquisition period. The total value of the interference index of the last data acquisition period of the carrier signal is smaller than the threshold value of the total value of the interference index, and the statistical value of the signal interference elimination period is greater than or equal to 1.
In step S410, if it is determined that the updated signal interference cancellation period statistic is greater than or equal to the fourth threshold, it is determined that the interference of the carrier signal is cancelled.
In the embodiment of the present disclosure, the fourth threshold is a critical value for determining whether the interference of the carrier signal is eliminated, and the fourth threshold may be determined based on actual needs, which is not limited in the embodiment of the present disclosure. Illustratively, the fourth threshold may be 2.
In an optional implementation manner, if the terminal determines that the updated signal interference cancellation period statistic is greater than or equal to the fourth threshold, which indicates that the carrier signal has an undisturbed condition with continuous data acquisition periods, and the number of continuous undisturbed data acquisition periods meets the interference cancellation determination condition, it determines interference cancellation of the carrier signal; and if the terminal determines that the updated signal interference elimination period statistic is smaller than the fourth threshold, determining that the interference of the carrier signal is not eliminated.
In step S411, if it is determined that the total interference index value of the previous data acquisition period is greater than or equal to the total interference index value threshold, it is determined that the interference of the carrier signal is not eliminated.
In step S411, if the terminal device determines that the total interference index value of the previous data acquisition period is greater than or equal to the total interference index value threshold, it may be determined that the carrier signal is interfered in the previous data acquisition period, the carrier signal does not have the situation of not being interfered in consecutive data acquisition periods, and the interference of the carrier signal is not eliminated. It can be understood that, since the carrier signal is not interfered in the current data acquisition period, the terminal device may update the signal interference cancellation period statistic of the carrier signal to 1, so as to determine whether the interference of the carrier signal is cancelled in the next data acquisition period.
Further, the terminal device may determine whether the current data acquisition period is the last data acquisition period corresponding to the carrier signal, and if the current data acquisition period is the last data acquisition period corresponding to the carrier signal, end the interference detection process of the carrier signal; and if the current data acquisition period is not the last data acquisition period corresponding to the carrier signal, detecting the interference condition of the carrier signal of the next data acquisition period.
Illustratively, as shown in fig. 5, fig. 5 shows a histogram of an interference detection result plot for a plurality of data acquisition periods of a carrier signal, wherein the abscissa represents the data acquisition period and the ordinate is used to indicate the total interference index value for the data acquisition period; if the total interference index value corresponding to the data acquisition period is smaller than or equal to the total interference index value threshold, the column height corresponding to the data acquisition period is smaller than or equal to 0, indicating that the carrier signal is not interfered in the data acquisition period, and if the total interference index value corresponding to the data acquisition period is greater than the total interference index value threshold, the column height corresponding to the data acquisition period is greater than 0, indicating that the carrier signal is interfered in the data acquisition period.

The process of combining the interfered sectors in the sector interference information map by the terminal device to obtain the updated sector interference information map may include: determining at least one first target sector of which the interference index total value in the current data acquisition period is greater than the interference index total value threshold, acquiring a second target sector of which the interference index total value is highest in the at least one first target sector, determining the distance values between the second target sector and other first target sectors, and determining and combining other first target sectors and second target sectors of which the distance values are less than the preset distance values.
Further, in at least one first target sector, a third target sector with the highest interference index total value in the first target sectors which are not combined is determined, distance values between the third target sector and other first target sectors which are not combined are determined, and other first target sectors which are not combined and have distance values smaller than a preset distance value are determined to be combined with the third target sector.

Wherein the preset distance value may be determined based on a scene of the base station. For example, if the communication base station is in a city, the preset distance value may be 1 km; if the communication base station is in a rural area, the preset distance value may be 5 km.
