Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, 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 only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
As described above, at present, when monitoring and maintaining a repeater, people with experience need to carry a spectrometer and a directional antenna to detect and identify whether the repeater is configured in a cell on the spot, and this method has high cost and low efficiency, and cannot meet the requirement of normalized network maintenance optimization after the network scale is enlarged. Therefore, the identification scheme capable of efficiently and conveniently determining whether the repeater is configured in the cell is provided.
FIG. 1 is a flowchart of a method for identifying a repeater configured in a cell according to an embodiment of the present invention, including the following steps:
s102, acquiring longitude and latitude information of the mobile equipment, and time advance information and reference signal receiving power information of a target cell corresponding to the mobile equipment from reported data of the mobile equipment.
The reporting of the data by the mobile device may include: minimum Drive-Test (MDT) data, over The Top (OTT) data, measurement Report (MR) data, etc., which are not listed herein.
Taking the minimum Drive-Test (MDT) data as an example, the MDT data can not only collect accurate position (longitude and latitude) information corresponding to a measurement result, but also support the collection of idle terminal measurement data, support the collection of related measurement data during an abnormal event, and support the measurement reporting of more measurement items.
The key fields in the MDT measurement report include:
1) The timing advance SCTadv (hereinafter referred to as TA value) of the serving cell. The TA value reflects the signal propagation time from the UE to the serving base station, which is a main indicator reflecting the distance between the UE and the serving base station. In mobile communication, in order to ensure orthogonality of uplink transmission signals and avoid intra-cell interference, uplink signals of different terminals are required to arrive at a base station side in time alignment, i.e., uplink synchronization. To achieve this, the base station needs to estimate the transmission delay caused by the distance of each terminal, and informs the terminal to send out data packets at a corresponding time (TA value) in advance. The unit of the TA value in MDT is Ts, which is defined in 3gpp Ts36.213, one Ts being about 0.03255us, corresponding to a distance equal to [3 × 108 × 1/(15000 × 2048) ]/2=4.89m, meaning distance = propagation speed (speed of light) × 1Ts/2 (sum of uplink and downlink paths). The distance corresponding to the TA command value is calculated with reference to 1 Ts.
2) The UE carries out positioning based on GPS, beidou, glonass and other satellite positioning systems to obtain position information, and the position information comprises UE longitude information and UE latitude information.
S104, based on the latitude and longitude information of the mobile device and the latitude and longitude information of the base station of the target cell, the distance between the mobile device and the target cell is calculated, and based on the time advance information of the target cell corresponding to the mobile device, the time advance distance of the target cell corresponding to the mobile device is calculated.
In particular to
May be based on a formula
Calculating a distance D between the mobile device and the target cell 1 (ii) a Where R is the earth radius, lonA represents longitude information of the target cell base station, latA represents latitude information of the target cell base station, lonB represents longitude information of the mobile device, and LatB represents latitude information of the mobile device. And the number of the first and second groups,
based on formula D 2 = SCAdv × 4.89, and the time advance distance D of the mobile device corresponding to the target cell is calculated 2 Wherein SCTadv is said moveThe time advance value of the mobile device corresponding to the target cell is 4.89, which is the time advance distance corresponding to the unit time advance value defined by the above-mentioned 3gpp ts36.213 protocol.
S106, determining the influence coefficient of the reported data of the mobile equipment by the repeater based on the distance between the mobile equipment and the target cell and the time advance distance of the target cell corresponding to the mobile equipment.
Under normal conditions, the difference between the longitude and latitude distance (hereinafter referred to as longitude and latitude distance) and the time advance distance (hereinafter referred to as TA distance) of the mobile device and the cell is small. After the signal is processed by the repeater, the TA distance is increased by at least about 553 × 4.89=2765 meters due to the signal processing delay of the repeater, so that the difference between the TA distance and the longitude and latitude distances is caused.
Here, for convenience of understanding, the TA value ranges affected by the repeater and not affected by the repeater, the average TA distance, and the comparison between the average TA distance and the difference between the latitude and longitude distances may be compared through the following table.
As can be seen from the above table, according to the field test result, the difference between the TA distance and the longitude and latitude distance of the regenerated signal processed by the repeater is larger, which is about 3000 meters; the difference between the TA distance and the longitude and latitude distance of the signal which is not processed by the digital optical fiber repeater is smaller, and is about 20 meters.
That is to say, the difference between the distance between the mobile device and the target cell and the distance of the time advance of the comfortable target cell corresponding to the mobile device can calculate the influence coefficient of the reported data of the mobile device on the repeater. The influence coefficient is used for judging whether the reported data is influenced by the repeater or not.
S108, determining whether the target is configured with the repeater or not based on the influence coefficient of the reported data corresponding to the target cell by the repeater.
Specifically, when the influence coefficient of the repeater on the reported data of the mobile equipment reaches a preset influence coefficient threshold value, the reported data of the mobile equipment is determined to be influenced by the repeater; the preset influence coefficient threshold is determined according to the cell signal amplification capacity of the repeater.
In this step, when the ratio of the reported data affected by the repeater and related to the determined target cell to all the reported data related to the target cell reaches the preset ratio threshold, it is determined that the repeater is configured in the target cell.
For example, as shown in the following table, if the reported data ratio affected by the repeater for a certain cell reaches 5%, it may be determined that the cell is a repeater information source cell, and the information source cell indicates a cell configured with a repeater.
In addition to the foregoing manner, it may also be determined that the repeater is configured in the target cell when the number of the reported data affected by the repeater related to the determined target cell reaches the preset number threshold, which is not described herein again for example.
The method of the embodiment of the invention calculates the distance between the mobile equipment and the target cell based on the longitude and latitude information of the mobile equipment carried by the reported data of the mobile equipment, and calculates the time lead distance of the mobile equipment corresponding to the target cell based on the time lead information of the mobile equipment corresponding to the target cell carried by the reported data, thereby determining the influence coefficient of the reported data of the mobile equipment on the repeater according to the distance between the mobile equipment and the target cell and the time lead distance of the mobile equipment corresponding to the target cell, further determining whether the repeater is configured for the target, and subsequently carrying out repeater maintenance on the cell where the repeater is deployed purposefully, thereby having the effect of assisting mobile network optimization.
The method of the present embodiment is described in detail below with reference to an actual application scenario.
In the application scenario, through the longitude and latitude information and the TA information of the data reported by the UE in the MDT data, whether the UE signal is subjected to extra time delay caused by the repeater on digital-to-analog conversion or not is analyzed, so that the UE signal is used as a key basis for judging whether the repeater is configured in a cell or not. The corresponding flow includes the following steps as shown in fig. 2:
reading MDT data, extracting key fields, and mainly comprising: sample time (single sample data acquisition time), cell identification ECI, cell frequency point, TA value, UE longitude and latitude information and the like.
And carrying out MDT sampling point grouping according to the ECI, traversing all ECI groups, and sequentially judging whether the cell is provided with the repeater or not.
Specifically, for the current ECI packet, each sampling point is traversed, and the longitude and latitude distances between the UE and each cell and the TA distance of the UE corresponding to each cell are calculated by using the UE position information contained in the MDT sampling point data.
For each cell, if (TA distance-longitude and latitude distance) > repeater distance difference threshold (set to 2700 meters according to the performance characteristics of the repeater), the number of the repeater sampling points of the cell is added by 1.
And completing the traversal of ECI packet sampling points, and if the total number of the repeater sampling points of a certain cell exceeds a threshold (such as 100) or the proportion of the repeater sampling points exceeds the threshold (such as 5%), judging that the repeater is configured in the cell.
In addition, corresponding to the identification method shown in fig. 1, the embodiment of the present invention further provides an identification apparatus for a cell configuration repeater. Fig. 3 is a schematic structural diagram of an identification device 300 implemented by the present invention, which includes:
an information obtaining module 310, configured to obtain longitude and latitude information of a mobile device, and timing advance information and reference signal received power information of a target cell corresponding to the mobile device from reported data of the mobile device;
a distance calculating module 320, configured to calculate a distance between the mobile device and the target cell based on the latitude and longitude information of the mobile device and the latitude and longitude information of the base station of the target cell, and calculate a time advance distance corresponding to the target cell for the mobile device based on the time advance information of the target cell corresponding to the mobile device;
a repeater influence determining module 330, configured to determine an influence coefficient of reported data of the mobile device on a repeater based on a distance between the mobile device and the target cell and a time advance distance of the mobile device corresponding to the target cell;

The device of the embodiment of the invention calculates the distance between the mobile equipment and the target cell based on the longitude and latitude information of the mobile equipment carried by the reported data of the mobile equipment, and calculates the time lead distance of the mobile equipment corresponding to the target cell based on the time lead information of the mobile equipment corresponding to the target cell carried by the reported data, thereby determining the influence coefficient of the reported data of the mobile equipment on the repeater according to the distance between the mobile equipment and the target cell and the time lead distance of the mobile equipment corresponding to the target cell, further determining whether the repeater is configured for the target, and subsequently carrying out maintenance on the repeater on the cell where the repeater is deployed purposefully, thereby having the effect of assisting mobile network optimization.
Optionally, the distance calculating module 320 is specifically based on a formula

The preset influence coefficient threshold is determined according to the cell signal amplification capacity of the repeater.
Or, the repeater configuration determining module 340 may further determine that the repeater is configured in the target cell when the determined number of the reported data affected by the repeater related to the target cell reaches a preset number threshold.
