Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the accuracy of positioning the TD-LTE uplink interference type, the embodiment provides a method performed by an OMC (Operation and Maintenance Center) or a device capable of performing data interaction with the OMC. Fig. 1 is a schematic flowchart of a TD-LTE uplink interference positioning method provided in this embodiment, and referring to fig. 1, the method includes:
step 101: acquiring interference information corresponding to each subframe in at least one type of subframe, wherein the interference information comprises interference noise of a Physical Resource Block (PRB) in the subframe; the at least one type of subframe comprises a special subframe and an uplink service subframe.
It should be noted that at least one type of subframe refers to various types of subframes that are helpful for positioning the uplink interference type, such as special subframes and uplink service subframes. The special subframe comprises a subframe 1 and a subframe 6, and the uplink service subframe comprises a subframe 2 and a subframe 7.
The step 101 comprises: interference noise corresponding to 100 PRBs (Physical Resource blocks) in subframe 1, subframe 6, subframe 2, and subframe 7 is obtained respectively.
Step 102: and respectively determining the subframe waveform corresponding to each subframe in each type of subframe according to the interference information.
In step 102, waveforms of interference noise with frequency, that is, sub-frame waveforms corresponding to sub-frames are generated for the interference information corresponding to sub-frames 1, 6, 2, and 7, respectively.
Step 103: determining the uplink interference type of the base station according to the subframe waveform corresponding to each subframe; the uplink interference types comprise far-end interference, GPS deviation interference, intra-network interference, external equipment interference and base station equipment problems.
Because the interference of different uplink interference types can cause different changes of the subframe waveforms, the uplink interference types are analyzed through the subframe waveforms corresponding to the subframes, and the uplink interference types can be accurately positioned according to the influence of the interference on each subframe.
In the TD-LTE uplink interference positioning method provided in this embodiment, a subframe waveform is determined for each type of subframe including an uplink service subframe and a special subframe, and an uplink interference type of a base station is determined according to the subframe waveform of each subframe in each type of subframe. The method has the advantages that the determination of the uplink interference type is refined to each subframe in each type of subframe, so that the determination of the uplink interference type is combined with the characteristics of the subframes in each type of subframe, all interference characteristics which are beneficial to determining the uplink interference type are reserved, the accuracy of TD-LTE interference type positioning is improved, and misjudgment is reduced.
Further, the step 103 includes:
judging whether each subframe in a first type subframe is interfered or not according to a subframe waveform corresponding to each subframe in the first type subframe, and judging whether each subframe in a second type subframe is interfered or not according to a subframe waveform corresponding to each subframe in the second type subframe;
(1) far-end interference: if the subframes in the first type of subframes are interfered, the subframes in the second type of subframes are not interfered, and the interference meets a first judgment condition, the uplink interference type is remote interference;
(2) a first method for determining intra-network interference: if all subframes in the first type of subframes are not interfered, subframes in the second type of subframes are interfered, and the interference meets a second judgment condition, the uplink interference type is intra-network interference;
the first type of subframe is a special subframe, and the second type of subframe is an uplink service subframe; the first judgment condition comprises that the interference is full-band interference, and the interference is influenced by time intervals and regions; the second judgment condition comprises that interference is influenced by a time interval, and the change of the subframe waveforms corresponding to the first type of subframe and the second type of subframe is inconsistent.
The embodiment provides a method for judging far-end interference and in-network interference, and realizes quick positioning of the far-end interference and the in-network interference.
Wherein, judge whether the subframe receives the interference according to the subframe waveform, including: and calculating the average value of interference noise corresponding to the PRB in the subframe waveform for any subframe waveform, wherein if the average value is greater than the preset noise, the subframe corresponding to the subframe waveform is interfered. Wherein the preset noise is-110 dBm.
Specifically, for the far-end interference located in (1) above, the determination may be performed only by subframe waveforms of the first type subframe and the second type subframe, where the first type subframe and the second type subframe satisfy the following conditions: subframe 1 and subframe 6 are interfered, and subframe 2 and subframe 7 are not interfered. Fig. 2 is a schematic diagram of a positioning process of far-end interference provided in this embodiment, and referring to fig. 2, the determining process includes further determining a subframe 2 and a subframe 7 if there is interference in the subframe 1 and the subframe 6, and if the subframe 2 and the subframe 7 are not interfered, the uplink interference type is far-end interference. Otherwise, the analysis needs to be continued in combination with the characteristics of the waveform to determine the uplink interference type.
In this embodiment, in order to further improve the accuracy of uplink interference type positioning, auxiliary determination is performed according to the first determination condition. Further, for the remote interference located in (1), there is also a rule that the uplink interference type can be further determined in combination with the rule in the actual determination process. The rule is as follows: in some cases, subframe 2 and/or subframe 7 may also be interfered after the interference source is beyond a certain distance from the base station.
Further, the first determination condition specifically includes:
frequency domain dimension: full band interference. Generally, in the northwest region, the PRB interference strength at the middle position in the subframe waveform may be lower than the remaining PRB interference strength in the subframe waveform. In the southeast coastal region, the PRB interference strength at the middle position in the subframe waveform may be higher than the remaining PRB interference strength in the subframe waveform.
The time dimension is as follows: the interference is periodic, and the interference time of different areas can be different. Generally, interference appears in the southeast coastal area at night, the interference gradually disappears in the daytime, and the far-end interference appears in the northwest area for a long time at present.
Regional dimension: the interference of provinces or cities is more serious, the influence of high stations in rural areas in suburbs is more serious, and the influence of urban sites is less or has no interference.

It can be seen that when a propagation delay occurs in a special subframe, the special subframe propagated in the next slot is affected. Fig. 4 is an interference waveform of the far-end interference in a certain area provided in this embodiment, and fig. 5 is an interference waveform of the far-end interference in another area provided in this embodiment, as can be seen from fig. 4 and fig. 5, the far-end interference is full-band interference, and is affected by time period and area, and meets the first determination condition.
Specifically, fig. 6 is a schematic diagram of a positioning process of intra-network interference provided in this embodiment, referring to fig. 6, for intra-network interference positioned in (2), there are two determination manners, one determination manner is determined by subframe waveforms of a first type subframe and a second type subframe, if subframe 1 and subframe 6 are not interfered and subframe 2 and subframe 7 are interfered, intra-network interference may be determined, and the other determination manner is that if subframe 1 and subframe 6 are interfered and subframe 2 and subframe 7 are interfered and satisfy a certain "waveform change law", intra-network interference may be determined. Wherein, the "waveform variation law" may include: whether the interference noise of the previous preset number of PRBs is lower than that of the rest PRBs or not is judged.
Further, referring to fig. 6, (2) a first determination method of intra-network interference: further comprising:
if the subframes in the first type of subframes are interfered and the subframes in the second type of subframes are interfered, judging whether the interference noise of the PRBs with the preset number is lower than that of the rest PRBs in the subframe waveforms corresponding to the subframes in the first type of subframes;
if the interference noise of the pre-set number of PRBs is lower than that of the rest PRBs in the subframe waveform corresponding to each subframe in the first type of subframe and meets the second judgment condition, the uplink interference type is intra-network interference;
and the rest PRBs are the PRBs after the PRBs of the preset number in the subframe waveform.
The embodiment provides another method for judging the intra-network interference, and the positioning of the intra-network jammer is realized.
Wherein the preset number is 4.
In this embodiment, in order to further improve the accuracy of uplink interference type positioning, the auxiliary determination is performed according to the second determination condition.

Frequency band dimension: subframe 1/subframe 6, which does not coincide with the interference waveform of subframe 2/subframe 7. Wherein, the waveform characteristics are as follows: and the interference waveforms of the subframe 2/the subframe 7 hour level are consistent, the interference waveforms are lifted in a segmented mode, and the interference intensity of the first 4 PRBs is weaker than that of other PRBs. The IOT (Interference over Thermal) of the first 4 PRBs of the UpPTS (Uplink Pilot Time Slot) of the subframe 1 and the last 4 PRBs of the UpPTS of the subframe 6 are much lower than those of other PRBs, and its IOT is close to the noise floor.
