Summary of the application
After an 800M/900M low frequency network is re-cultivated from LTE (Long Term Evolution ) to NR (New Radio interface), external interference, such as interference of a private repeater, interference of a parking lot and an expressway gateway, is still a main source, and the interference problem will directly affect user experience, such as reduction of uplink rate, increase of drop rate, reduction of RRC (Radio Resource Control protocol) establishment success rate, and the like.
At present, an uplink interference measurement method of an FDD (Frequency Division duplex) system generally includes two means, namely, manual Frequency sweeping and system data analysis, wherein the manual Frequency sweeping obtains Frequency domain characteristics interfering a certain moment, if the interference characteristics need to be obtained comprehensively, a large amount of time needs to be consumed, and requirements on professional level and working experience of network optimization personnel are high. The system data analysis mainly comprises the network management data analysis at the base station side and the MR (Measurement Report) side data analysis at the terminal side, and interference characteristics are obtained. However, the method for obtaining the system terminal MR is not suitable for the initial stage of 5G re-cultivation, because the amount of users is small, and the traffic volume of the cell can raise the cell background noise and the background noise on a certain PRB (Physical Resource Block), so that the background noise data cannot represent the actual external interference level when the traffic load is relatively large, fig. 1 is a schematic diagram of the background noise variation of a certain non-interference cell in one day (the data is from the average value of the received interference noise of each uplink PRB collected by the network management side), the horizontal axis is small, the vertical axis is the background noise, and the unit dBm, as can be seen from fig. 1, the non-external interference factors still affect the cell background noise level. If only the interference characteristic analysis is selected in idle time, the interference characteristic is lost, and the interference measurement is deviated.
In view of the above technical problems, the present application provides an uplink interference measurement method, apparatus, and readable storage medium, which can remove the influence of cell uplink service on the background noise, obtain the background noise level caused by only external interference, and avoid the occurrence of deviation in interference measurement, thereby facilitating subsequent interference characteristic analysis, interference identification, positioning, and removal by performing uplink muting on target subframes of a cell to be measured and neighboring cells and performing interference level measurement during uplink muting.
Having described the basic principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Example 1:
the present embodiment provides an uplink interference measurement method, which is applied to a cell base station to be measured, and as shown in fig. 2, the method includes:
step S101: and performing uplink silencing on the target subframe of the cell to be tested according to the uplink silencing parameter of the pre-configured cell to be tested.
Step S102: sending an uplink silent opening message carrying uplink silent parameters of the neighbor cell to the neighbor cell base station, so that the neighbor cell base station performs uplink silent on the target subframe of the neighbor cell according to the uplink silent parameters of the neighbor cell;
step S103: and measuring interference data of the cell to be measured and the base station of the adjacent cell during uplink silence to obtain a corresponding uplink interference value.
In this embodiment, the target subframe generally refers to any subframe in a radio frame, the interference data may be a background noise, and since a user may raise the background noise when performing an uplink service, the acquired background noise is larger than an actual external interference value, in order to remove factors in the system that affect the background noise, uplink muting needs to be performed on a cell to be measured and a neighboring cell thereof when performing interference level acquisition, that is, uplink service is not performed, in order to not affect an uplink rate, uplink muting may be performed only on a certain subframe, so that cell and user performance are hardly affected, and the measured background noise may directly reflect the interference level.
Specifically, fig. 3 shows a schematic diagram of performing uplink muting on subframe 2, and as shown in fig. 3, the cell to be measured (i.e., the local cell) and its neighboring cells do not perform uplink service on subframe 2 at the same time, so that the influence of the uplink service of the cell on the background noise can be removed when interference level acquisition is performed, and an actual external interference level is obtained.

(2) After receiving the message, each adjacent cell base station starts uplink silence in the next subframe of the time point of starting silence, namely the uplink does not send any data, the rest subframes normally send data, and the repeated operation is carried out according to the period;
(3) Measuring interference data of a cell to be detected and an adjacent cell base station during uplink silencing, wherein the base noise level can represent the actual external interference level because the target subframe does not have the uplink service of the cell and the adjacent cell, obtaining the average PRB base noise level of the cell and the base noise level of each PRB, and further drawing an interference time domain diagram and a frequency domain characteristic diagram of the corresponding cell so as to realize the analysis of the interference type and the positioning of an interference source;
(4) When the uplink interference measurement needs to be finished, the base station of the cell to be measured sends an uplink silence finishing message to the base station of the adjacent cell through an X2 interface, wherein the uplink silence finishing message carries the PCI of the silent cell, and the message is configured to the cell to be measured;
(5) And after receiving the message, each adjacent cell base station stops performing uplink silencing on the target subframe of the adjacent cell according to the uplink silencing end message, and at the moment, the adjacent cell and the cell to be tested recover to be normal.
