Description

Base station testing method and system, terminal and cloud server

Technical Field

The invention relates to the technical field of communication, in particular to a base station testing method and system, a terminal and a cloud server.

Background

At present, a base station must first undergo a single-station (single-base-station) verification test before accessing a network for service, so as to ensure that the base station parameter information such as the installation condition, parameter configuration and the like of the base station is consistent with the planning parameter information in a planning scheme, and ensure that the basic functions (such as access, voice call, FTP uploading and downloading services and the like) and signal coverage of each cell in the coverage area of the base station site are normal, thereby reducing adverse effects on later maintenance and optimization.

The existing base station test flow is as follows: after receiving a test task, a tester first determines a basic parameter information list of a base station to be tested, such as a base station name, a base station address, base station location information (longitude and latitude), an antenna hanging height, a direction angle, a downward inclination angle (including a mechanical and electronic downward inclination angle), planned cell data (such as a base station ID, a cell ID, a frequency point) and the like, and before going to a station, the tester needs to check all test instrument devices, so that the test is prevented from being influenced by device problems, for example: the equipment needing to be checked comprises a vehicle, a vehicle-mounted inverter, a testing computer, a power line, drive test software, a testing terminal, a USB (universal serial bus) connection data line, a camera, a GPS (global positioning system) for the computer, a handheld GPS, a USB Hub, a SIM (subscriber identity module) card, a compass (used for measuring the azimuth angle and the mechanical inclination angle of an antenna), a paper map and the like. Then, the tester acquires information such as base station position information, antenna hanging height, direction angle, downward inclination angle, base station sky picture and the like on the base station according to the determined basic parameter information list; and executing a network test case at a preset test point, for example: manually completing fixed point and mobile service tests such as access, voice call, FTP uploading/downloading, switching and the like; then, the tester returns to the station, manually inputs and analyzes the test data, and compares the results; manually integrating test data, base station photos, test coverage maps and other base station information by testers, and sorting and outputting test reports; if the test data can not meet the judgment standard or part of test items are missed, the tester needs to go to the station for retesting for the second time until the test is passed.

Therefore, the existing base station test scheme mainly has the following problems:

firstly, the preparation work before the tester is on station is too complex, the required test instrument tools are numerous, and whether the tester is actually on station can not be verified;

secondly, different test cases need to use different test equipment, the operation is complex, and the requirement on the technical level of testers is high. For example, the longitude and latitude acquisition of a base station needs to use a handheld GPS; the collection of the antenna direction angle and the downward inclination angle information needs to use a compass; the network test requires a special test notebook to be externally connected with a test terminal and an external GPS and load drive test software; testers need to be skilled in mastering the use methods of various instruments and tools, so that the operation complexity is high;

moreover, post-processing analysis of the test data is manually completed, and the test data has great difference due to different levels of field testers; particularly, for the problems in the network, such as antenna feeder reverse connection and antenna feeder blocking, at present, the manual judgment of a tester is relied on, and the test accuracy completely depends on the experience and responsibility of the tester, so that serious misjudgment and missed judgment are easily caused, and the difficulty is increased for later-stage network optimization.

In summary, the existing base station testing scheme has the problems of high complexity, low accuracy, low testing efficiency and the like, and a more suitable base station testing scheme needs to be found urgently.

Wherein, the network test case may further include: indoor network test cases, for example: base station level test cases (indoor and outdoor switching), cell level tests (attachment/detachment, voice call CSFB), and floor level traversal FTP uploading/downloading test cases; outdoor network test cases, for example: base station level test cases (FTP upload/download drive tests), cell level test cases (attach/detach, voice call CSFB).

The technical solutions according to the present invention are described in detail below by specific schemes, and the present invention includes, but is not limited to, the following examples.

Example one

As shown in fig. 2, a schematic step flow chart of a base station testing method according to an embodiment of the present invention is provided, where the testing process mainly includes:

step 21: and the cloud server receives the identification of the base station to be tested, which is sent by the terminal.

Wherein the base station to be tested is determined by the terminal.

Step 22: the cloud server searches a stored test plan list according to the identification of the base station to be tested, and matches a test plan corresponding to the identification of the base station to be tested, wherein the test plan comprises a parameter test case and a network test case.

The parameter test case may specifically be: acquiring basic parameter information of a base station to be tested, acquiring engineering parameter information of the base station, and acquiring site information of the base station.

The network test case may specifically be: various information interaction such as LTE access, voice call CSFB, FTP uploading/downloading and the like is carried out between the terminal and the base station, and meanwhile, various test data in the test process are collected.

Step 23: and the cloud server sends the test plan to the terminal so that the terminal tests the base station to be tested according to the test plan.

In a specific implementation process, the terminal performs tests according to the parameter test cases and the network test cases in the test plan.

Step 24: and the cloud server acquires test data obtained by the terminal test in real time, and analyzes the test data to obtain a test result aiming at the base station to be tested.

According to the cloud server, the test data obtained by the terminal test are obtained in real time and are automatically analyzed, so that the problems that the test is inaccurate and the test result is not fed back timely due to the fact that the test data obtained by the terminal is manually analyzed in the prior art are solved.

Optionally, the cloud server analyzes the test data, and specifically may include at least the following test cases:

a test case I:

and the cloud server determines whether the base station parameter information obtained according to the parameter test case test in the test data is consistent with the planning parameter information.

For example: comparing the longitude and latitude of the base station, the hanging height of the cell antenna, the azimuth angle of the cell, the downward inclination angle of the cell antenna and the like in the base station work parameter information obtained by testing with planning parameter information, if the base station work parameter information is consistent, the base station work parameter information of the base station to be tested is correct, the base station to be tested does not need to be debugged, and if the base station work parameter information is inconsistent, a tester or other debuggers need to go up to carry out debugging work on the base station parameters, so that the base station work parameter information of the base station to be tested is adjusted to be consistent with the planning parameter; in addition, other base station basic information and base station field information need to be compared and analyzed according to the method, and whether the base station to be tested is debugged or not is further determined. By the test scheme, the base station basic information which does not accord with the plan in the base station to be tested can be reasonably debugged, so that the base station to be tested can possibly be used as the base station which accords with the standard to execute the network access service.

In fact, the single-station test of the base station includes not only the comparison and analysis of the base information of the base station, but also the analysis of the network information interaction condition between the base station to be tested and the terminal, which is embodied as analyzing according to the test data obtained during interaction, as shown in the following test case two and test case three.

And a second test case:

and the cloud server determines whether the cell of the base station to be tested has antenna feedback connection feedback according to the test data.

Optionally, as shown in fig. 4, which is a flowchart illustrating a specific execution step of the second testing scheme of the present invention, the second testing scheme may analyze whether an antenna feedback exists in a cell of a base station to be tested according to the following steps:

step 41: and screening the test point position information of all the cells from the test data.

Step 42: and determining whether the cell is a suspected antenna feed back cell according to the position information of the test point of each cell.

In particular, this step 42 may be specifically performed as:

the first step is as follows: determining an included angle between the test point and the main direction of the current cell according to the position information of each test point in the cell and the position information of the base station;

the second step is that: counting the occupation ratio of the test points with the included angle larger than the preset angle value in the current cell;

the third step: and judging whether the occupation ratio is larger than a first threshold value or not, if so, determining that the current cell is a suspected antenna feeder connection feedback cell, and otherwise, determining that the current cell is an antenna feeder connection normal cell.

Step 43: and counting the number of the cells which are determined as suspected antenna feedback cells in all the cells.

Step 44: and judging whether the number of the cells is larger than a second threshold value, if so, determining that the cells of the base station to be tested have antenna feed connection feedback, and otherwise, determining that the cell antenna feed connection of the base station to be tested is normal.

As shown in fig. 5, a coverage area diagram of three cells of a base station to be tested is shown, where the three cells A, B, C are respectively shown in a sector area, each cell corresponds to a main direction Li of the cell, and various dots filled with patterns in the diagram represent tests of network communication quality performed by a worker around the base station to be tested, where the positions of the dots represent test point positions, and the patterns of the dots represent different signal strengths.

In general, there are 3 cells corresponding to a base station, and if there is an antenna feeder feedback, there must be at least two cells with antenna feeder feedback, so when verifying the antenna feeder connection problem of the cell of the base station to be tested:

first, test point location information of all cells is screened from test data, for example: location information of all test points of the cell a (e.g. an area sandwiched by extension lines of two boundaries of a sector area of the cell a in the figure), location information of all test points of the cell B, and location information of all test points of the cell C.

For example, for test point a1, test point a2 and test point a3 in cell a, the included angles α 1, α 2 and α 3 between each test point and the main direction of the current cell are respectively determined according to the respective test point position information and the base station position information.

Secondly, in the included angles α 1, α 2, and α 3, the percentage of the test point in the current cell that is greater than the preset angle value is counted, and whether the percentage is greater than a first threshold is further determined, if yes, the current cell is determined to be a suspected antenna feeder connection feedback cell, otherwise, the current cell is determined to be an antenna feeder connection normal cell.

And then, determining the antenna feeder connection condition of the cell B and the cell C according to the mode.

And finally, counting the number of the cells which are determined to be suspected antenna feed back cells in all the cells, and considering that the situation of antenna feed back inevitably affects at least two cells, therefore, when the number of the cells which are determined to be suspected antenna feed back cells is more than 2, determining that the cell of the base station E to be tested has antenna feed back, if the number of the cells which are determined to be suspected antenna feed back cells is less than 2, determining that the cell antenna feed connection of the base station to be tested is normal, and the reason for determining to be suspected antenna feed back cells may be other connection problems.

By the mode, the reverse situation of antenna feeder connection of the cell of the base station to be tested is analyzed by using the test data obtained by field test, a real test result can be accurately and effectively obtained, and the problems of inaccuracy and low efficiency caused by manual subjective judgment according to the difference of the point position of the field test point and the orientation of the cell in the prior art are solved. Moreover, the mode is favorable for unifying the test standards, ensures that the tests of all the base stations to be tested are the same test standards, and avoids the difference and inaccuracy caused by manual participation and subjective judgment.

And (3) test case III:

and the cloud server determines whether the cell of the base station to be tested has antenna feeder blockage according to the test data. The antenna feeder blocking means a blocking object for blocking signals between the base station to be tested and the test point, for example: a large mountain and an office building can be used as barriers.

Optionally, as shown in fig. 6, a flowchart of a specific execution step of the third testing scheme of the present invention is shown, where the third testing scheme may analyze whether there is an antenna feeder blocking in a cell of a base station to be tested according to the following steps:

step 61: for any cell: and screening the test point position information of all test points in the cell from the test data, and determining the empty path loss of each test point.

Optionally, step 61 is specifically executed as: according to the position information of the test point and the position information of the base station in the test data, determining the air interface path loss of the test point by using the following space propagation model formula:

wherein, the

It should be noted that the above spatial propagation model formula can be specifically transformed into an OKUMURA-HATA model or a COST-HATA model, and specifically, the model can be selected according to different values of the signal frequency f with reference to the following table, where different spatial propagation models have different coefficients:

TABLE 1

Step 62: and determining the predicted receiving level value of each test point according to the determined air interface path loss.

Specifically, the predicted reception level value is air interface transmission power-air interface path loss, where the air interface transmission power is generally 20W.

And step 63: and subtracting the actually measured receiving level value corresponding to each test point from the predicted receiving level value to obtain a difference value, and counting the occupation ratio of the test points of which the difference values are greater than a third threshold value in the current cell.

The actually measured receiving level value is a type of test data collected by using a network test case.

Step 64: and judging whether the occupation ratio is larger than a fourth threshold value, if so, determining that the cell of the base station to be tested has the antenna feed blockage, and otherwise, determining that the cell of the base station to be tested does not have the antenna feed blockage.

For each base station, air interface path loss does exist, however, in order to ensure the network signal strength of the cell covered by the base station, a smaller obstacle can be ignored, so when determining whether an antenna feeder blockage exists in the cell of the base station to be tested, it is necessary to determine the occupation ratio of the test points with the difference values larger than the third threshold value in all the test points of the current cell, if the occupation ratio is larger than the fourth threshold value, it is indicated that the measured reception level values of the plurality of test points in the cell are deviated from the predicted reception level values, the cell has an antenna feeder blockage, otherwise, it is determined that the cell does not have an antenna feeder blockage, and the network signal coverage condition in the cell is good.

It should be noted that the first threshold, the second threshold, the third threshold, and the fourth threshold mentioned above may be flexibly selected according to an actual test environment, and the present invention is not limited to this.

Step 25: and the cloud server sends the test result to the terminal.

Optionally, in order to improve the safety and the authenticity of the test scheme, as shown in fig. 3, before performing step 21, the test process further includes the following steps:

step 31: and receiving terminal position information or base station keyword information sent by the terminal.

Specifically, the terminal position information or the base station keyword information is automatically determined by the terminal according to the position of the terminal, and is sent to the cloud server through the confirmation operation of the tester. Therefore, the position information of the terminal or the keyword information of the base station does not need to be manually input by a tester, and the condition that the test point does not accord with the test data due to manual input is avoided.

Step 32: and matching a base station list to be tested containing at least one base station identifier according to the terminal position information or the base station keyword information, and sending the base station list to be tested to the terminal, so that the terminal determines the base station to be tested from the base station list to be tested according to the requirements of users.

Because the test point may not be covered by only one base station, after the cloud server matches a series of base station identifications according to the received terminal position information or the base station keyword information, a list of base stations to be tested is formed; and then, the cloud server sends the list of the base stations to be tested to the terminal, and then the list is displayed to the tester through the terminal, so that the tester can select the base stations to be tested.

It can be seen that the execution of the

above steps

31 and 32 can bring the following effects: on one hand, the terminal position information or the base station keyword information acquired by the cloud server is completely determined automatically by the terminal according to the position of the terminal, and the conditions that a tester manually inputs and modifies data are not involved, so that the authenticity of the test point and the test data is ensured. On the other hand, the cloud server needs to match a list of base stations to be tested according to the acquired terminal position information or the base station keyword information and then send the list to the terminal so that a tester can determine the base stations to be tested, thereby realizing the security verification of the terminal by the cloud server and ensuring that the terminal interacting with the cloud server is the terminal used for testing the base stations.

and then, the terminal receives the base station list to be tested and determines the base station to be tested from the base station list to be tested according to the requirements of users.

Step 73: and sending the acquired test data to a cloud server in real time, so that the cloud server analyzes the test data to obtain a test result for the base station to be tested.

In this step 73, different from the prior art, the terminal sends the collected test data to the cloud server in real time, and does not perform manual analysis on the test data after collecting all the test data, in particular, perform manual comparison on the base station parameter information and perform manual determination on the antenna feeder connection and the antenna feeder blocking condition according to the test data.

Step 74: and receiving a test result sent by the cloud server.

According to the technical scheme, the test of the base station to be tested and the acquisition of test data can be realized through the information interaction of the cloud server and the terminal, a tester is not required to utilize various test tools to test for many times, the use of the test tools and the complexity of the test are reduced, in addition, the terminal sends the acquired test data to the cloud server in real time for analysis and processing, the inaccuracy and the non-uniformity of the test result caused by manual analysis are avoided, the subsequent maintenance optimization work is influenced, the accuracy and the automation of the analysis and processing are improved, and the efficiency of the whole test scheme is improved. Moreover, because the test data is transmitted in real time, the cloud server can find the problems of error test, missing test and the like in time so as to carry out retest, and the complexity of needing to return to a station for retest for the second time in the prior art is completely avoided.
