Description

Method and device for checking cell signal leakage

technical field

The invention relates to the field of communication technology, in particular to a method and device for checking cell signal leakage.

Background technique

At present, for mobile communication networks, indoor leakage is a problem of great concern. Leakage of indoor signals refers to the propagation of mobile communication signals that should cover indoors to areas covered by outdoor macro cells. The impact is mainly reflected in the terminal in the coverage area of the outdoor macro cell, which is relatively close to the coverage area of an indoor cell. At this time, the terminal may detect a strong indoor signal and switch to the indoor cell. Since the leakage of indoor cells is often covered by pinpoints, and the coverage drops suddenly outdoors, it is possible that when the terminal switches from the indoor cell to the macro station, the call drop due to the sudden drop in the signal level may cause the handover to fail. Seriously affect the service experience of users on the operator's network.

At the same time, the intrusion of the macro cell signal into the indoor distribution system will also cause the above-mentioned similar problems, such as the steep drop of the indoor environmental signal, the interference between the indoor distribution signal and the macro cell signal, etc., which affect user perception. In addition, since the indoor distribution system is deployed, the macro cell There is no need to invade the room distribution system to share the traffic of the room distribution system.

However, the prerequisite for the optimization work of indoor leakage and macro cell intrusion is to find the base station of indoor leakage and macro cell intrusion and understand the severity of the related problems. At present, indoor leakage and macro cell intrusion are mainly checked and verified by drive test equipment, that is, network optimization personnel carry test equipment around buildings with indoor cell distribution to check indoor leakage, or check macro cell signal intrusion indoors question. Drive testing is carried out by network optimization personnel on a regular basis across the entire network, or in areas where user complaints or network key performance indicators (KPIs) are abnormal. However, due to the wide distribution of indoor and outdoor collaborative scenarios, drive testing is time-consuming and laborious, and it is difficult to conduct a comprehensive inspection of signal leakage.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

An embodiment of the present invention provides a method for checking cell signal leakage, as shown in Figure 1, the method includes:

101. Acquire a measurement report MR reported by a terminal.

Wherein, the terminal periodically or aperiodically measures the cells in which the terminal can detect signals, and the cells in which the terminal can detect signals include the main serving cell of the terminal and other cells. Then, the terminal forms an MR to report the detected measurement results of each cell to the equipment on the access network side, such as base station, RNC and other equipment.

Wherein, the MR includes the identifier of the primary serving cell of the terminal and the signal strength information of the primary serving cell, the identifier of the other cell and the signal strength information of the other cell.

Wherein, the signal strength information of the primary serving cell and the signal strength information of the other cells may be: signal level strength or useful signal ratio information of the primary serving cell and the other cells.

Specifically, if the primary serving cell and the other cells are cells of a WCDMA communication system, the signal strength information of the primary serving cell and the signal strength information of the other cells are: received signal code power RSCP, signal-to-interference ratio Ec /Io, signal-to-noise ratio Ec/No.

If the other cell in the MR is a cell of the GSM communication system, the signal strength information may be: level strength Rex level, signal-to-interference ratio C/I, etc.;

If the other cell in the MR is a cell of the LTE communication system, the signal strength information may be: cell-specific reference signal strength RSRP, signal-to-noise ratio RSRQ, signal-to-interference-noise ratio SINR, and the like.

102. Acquire a first reference number of sampling points according to the identity of the primary serving cell.

Wherein, the first reference sampling point may be an MR selected from MR sampling points of the whole network and including the primary serving cell being the first cell.

Optionally, the first reference sampling point may also be an MR where the primary serving cell is a first cell and the signal strength information of the primary serving cell is greater than a second preset threshold.

103. Obtain the number of signal leakage sampling points, the signal leakage sampling point is that the main serving cell is the first cell, the other cells include the second cell, and the signal strength information of the cell with the highest signal strength is the same as the second cell The difference between the signal strength information of the two cells is less than the MR of the first preset threshold.

Wherein, the first cell and the second cell are respectively a macro cell and an indoor cell, or are respectively an indoor cell and a macro cell.

Specifically, the MR whose difference between the signal strength information of the cell with the highest signal strength and the signal strength information of the second cell is smaller than a first preset threshold may be selected from all the first reference sampling points; of course, it may also be Filter from the MR data of the whole network, where the filter conditions must meet the following conditions:

(1) The primary serving cell is the first cell;

(2) The other cells include the second cell;

(3) An MR whose difference between the signal strength information of the cell with the highest signal strength and the signal strength information of the second cell is smaller than a first preset threshold.

Of course, it should be noted that no matter whether the signal leakage sampling points are screened from all the first reference sampling points or all the MR data of the whole network, it can screen the signal strength information of the cell with the highest signal strength and the first The difference between the signal strength information of the two cells is less than the MR of the first preset threshold; the MR whose signal strength information of the second cell is greater than the third preset threshold can also be screened; the signal strength of the first cell can also be screened An MR whose difference between the information and the signal strength information of the second cell is smaller than a fourth preset threshold.

Of course, to filter signal leakage sampling points, if the difference between the signal strength information of the cell with the highest signal strength and the signal strength information of the second cell is less than the MR of the first preset threshold, it can be more easily identified Output signal leakage sampling point. The reason for this is that the difference between the signal strength information of the cell with the highest signal strength and the signal strength information of the second cell can better reflect whether the second cell leaks signals to the first cell.

For example, in MR data, the signal of the primary serving cell may be particularly weak, while the signals of some cells in other cells are often stronger than the signal of the primary serving cell. At this time, if the difference between the signal strength information of the primary serving cell and the signal strength information of the second cell is used to screen the signal leakage sampling points, the selected signal leakage sampling points may not be accurate enough. The information thus provided may cause misjudgment by network optimization personnel.

Wherein, it should be noted that the signal leakage sampling point may be an indoor division signal leakage sampling point or a macro station intrusion sampling point. The indoor signal leakage sampling point refers to: the first cell is a macro cell, the second cell is an indoor cell, and the signal strength information of the cell with the highest signal strength is the same as the signal strength of the second cell The information difference is less than the MR of the first preset threshold. The macro station intrusion sampling point refers to: the first cell is an indoor cell, the second cell is a macro cell, and the signal strength information of the cell with the highest signal strength and the signal strength of the second cell The information difference is less than the MR of the first preset threshold.

The reason is that no matter whether it is room division leakage or macro station intrusion, it depends on the proportion of strong signals. Therefore, using the signal strength information of the cell with the highest strength as the calculation benchmark has certain advantages and can better reflect actual problems.

For example, in a WCDMA system, the RSCP in the MR can be selected as the signal strength information, and the specific screening method is as follows: Assuming that the first cell in MR1 is a macro cell, and the signal strength of the first cell is the strongest, The second cell is an indoor cell, and the difference obtained by subtracting the RSCP value of the second cell from the RSCP value of the first cell is less than or equal to 6dB (if the difference is negative, it also meets the condition of being less than or equal to 6dB), then The MR1 is considered to be the sampling point of the compartment leak.

If macro station intrusion is judged, the first cell is an indoor cell, and the second cell is a macro cell. The calculation process is similar, and the statistics are for signal leakage in the opposite direction, which will not be repeated here.

It should be noted that, if the signal leakage sampling points are screened from all the first reference sampling points, step 102 and step 103 may be performed in no particular order. That is, the number of first reference sampling points can be obtained first, and then the number of signal leakage sampling points can be obtained; of course, the number of signal leakage sampling points can be obtained first, and then the number of first reference sampling points can be obtained; of course, the first reference sampling points can also be obtained at the same time The number of points and the number of signal leakage sampling points are not specifically limited in this embodiment of the present invention.

104. Determine whether the signal of the second cell leaks to the first cell according to a ratio of the number of signal leakage sampling points to the number of first reference sampling points.

Specifically, a ratio of the number of signal leakage sampling points to the number of first reference sampling points is calculated. Then judge whether the signal of the second cell leaks to the first cell according to the ratio. Wherein, the larger the ratio is, the more serious the leakage of the signal of the second cell to the first cell is.

Specifically, network optimization personnel can determine whether to perform optimization processing on the first cell and the second cell based on this.

It should be noted that, in the description process, the embodiment of the present invention is directed to the cell pair of the first cell and the second cell, that is, it is judged whether the signal of the second cell leaks to the first cell. Of course, for the MR data of the whole network, the method provided by the embodiment of the present invention is applicable to the cells of the whole network, which can traverse the data of the whole network to check the signal leakage problem of each cell pair. Wherein, the first cell may be any primary serving cell in the MR data of the entire network, and the second cell may be any cell included in other cells in the MR data of the entire network. Of course, the embodiment of the present invention discusses the problem of signal leakage, so the above-mentioned cell pair of the first cell and the second cell refers to a cell pair composed of a macro cell and an indoor cell.
