Description

High-speed rail simulation drive test data acquisition method and device

Technical Field

The embodiment of the invention relates to the technical field of mobile communication, in particular to a method and a device for acquiring high-speed rail simulation drive test data.

Background

With the development of science and technology, transportation is also rapidly developed, and particularly, the appearance of high-speed rails facilitates the travel of people. In order to facilitate the operation control of the high-speed rail and the use of users on the high-speed rail, a special mobile communication network, which is called a private network for short, is established for the high-speed rail. When people go out on a high-speed rail, people can still talk or surf the internet through a mobile communication network covering the high-speed rail.

However, since the high-speed rail has a faster operation speed, it is more difficult to ensure the network quality, and it is usually necessary to test the high-speed rail network to evaluate the service condition of the network, the service state of the high-speed rail station, and the perception condition of the user, especially the VIP user, when the user moves on the highway, and to optimize the high-speed rail network to improve the communication quality of the user. In the prior art, a method for testing a high-speed rail network, namely testing a high-speed rail, generally includes that a tester carries test equipment, rides a high-speed rail, obtains test data and tests the high-speed rail network, namely testing a high-speed rail. Because the number of high-speed rail lines is increased, the number of high-speed rail networks to be tested is also increased, and therefore, in the prior art, the resource demand of the high-speed rail network test, such as resources of manpower, equipment and the like, is relatively high. In addition, if the high speed has a long line overlapping coverage with the high-speed railway (in fact, this is the case in many cases), the high-speed users may fall into the private network and occupy a certain time for operating the private network cell for one reason or another, and since the high speed and the high-speed railway operate at speeds very close to each other under certain road conditions (such as approaching to the urban area or temporarily stopping in the middle), these high-speed users may be mistakenly identified as high-speed railway users, which results in inaccurate selection of target users, which may cause great deviation to the result of the high-speed railway network test, i.e., the high-speed railway test, and may mislead the next optimization work.

Therefore, how to provide a method which can save the resources required by the traditional high-speed railway survey becomes an urgent problem to be solved.

And pre-establishing high-speed rail line cell list information of the high-speed rail line to be tested, wherein the high-speed rail line cell list information comprises a high-speed rail cell number of the high-speed rail line cell corresponding to the high-speed rail line to be tested and high-speed rail line direction information of the high-speed rail line to be tested. The high-speed rail line cell is a network cell of a high-speed rail special network with a signal coverage range covering the high-speed rail line to be tested, and different high-speed rail line cells may correspond to different directions of the high-speed rail line to be tested, so that the high-speed rail line direction information of the high-speed rail line to be tested is stored in the high-speed rail line cell list information of the high-speed rail line to be tested in the embodiment of the invention. Such as: if the high-speed rail to be tested is a high-speed rail in the east-west direction, the information of the high-speed rail cells from east to west can be stored as one high-speed rail cell list information, and the information of the high-speed rail cell from west to east can be stored as another high-speed rail cell list information, namely, one high-speed rail to be tested can correspond to two high-speed rail cell list information and can be used as two high-speed rails to be tested. When the network service quality of a high-speed rail line to be tested needs to be tested, the cell list information of the high-speed rail line to be tested and the occupied cell list information of the user terminal in a preset time period are obtained. The occupied cell list information includes the number information of the network cell occupied by the user terminal in the preset time period and the corresponding time when the network cell is occupied. In addition, the sequence of network cells occupied in the cell list information may be arranged according to the time sequence of the cells occupied by the user terminal.

The preset time period may be set as required, and specifically, the operation time of the high-speed rail line to be tested may be obtained for setting, if the operation time of the high-speed rail line B to be tested is from 9 am to 3 pm each day, the preset time period may be set from 9 am to 3 pm, and of course, other preset time periods may be set as required, which is not specifically limited in the embodiment of the present invention.

And S3, if the user terminal is judged to meet the preset conditions, taking the user terminal as a target user terminal of the high-speed rail simulation drive test, and taking the communication data of the target user terminal as the high-speed rail simulation drive test data.

Specifically, if the user terminal is judged to meet the preset conditions according to the occupied cell list information and the high-speed rail line cell list information, the user terminal is used as a target user terminal of the high-speed rail simulation drive test, communication data of the target user terminal is used as high-speed rail simulation drive test data, and the network service quality of the high-speed rail line to be tested is further tested. Wherein the communication data of the user terminal may include: the signal intensity of the service cell, the voice quality, the signal intensity indication Ec and the signal quality indication Ec/Io of the adjacent cell, the signaling process of switching and accessing, the cell identification code, the area identification code, the service establishing success rate, the switching proportion, the average throughput rate of the uplink and the downlink, the geographic position of the mobile phone, the call management, the mobile management \ the service establishing delay and the like. And further counting to obtain KPIs (Key Performance Indicators) of the high-speed railway to be tested and abnormal events of the wireless network, wherein the KPIs are used for evaluating the service quality of the network and optimizing the wireless network.

The occupied cell list information and the communication data of the user terminal may be obtained by obtaining interface data in the LTE network, specifically, may be obtained by obtaining MR (Measurement Report) data of a control plane, a user plane and the user terminal of the target user terminal, or may be obtained by other methods.

According to the method for acquiring the high-speed rail simulation drive test data, provided by the embodiment of the invention, the two list information are analyzed by acquiring the occupied cell list information of the user terminal and the high-speed rail line cell list information of the high-speed rail to be tested, the target user terminal is identified, and the communication data of the target user terminal is used as the high-speed rail simulation drive test data. The interface data in the LTE network are directly obtained to obtain the high-speed rail simulation drive test data, redundant test equipment is not needed, and resources required by the traditional high-speed rail test are saved.

On the basis of the above embodiment, the determining whether the user terminal satisfies a preset condition includes: if the user terminal is judged to meet the first preset sub-condition and the second preset sub-condition at the same time, determining that the preset condition is met, wherein:

satisfying the first preset sub-condition comprises: acquiring a first number of the occupied cell list information belonging to the high-speed rail line cells in the high-speed rail line cell list information and a total number of the high-speed rail line cells in the high-speed rail line cell list information according to the occupied cell list information and the high-speed rail line cell list information, taking a ratio of the first number to the total number as a ratio of the occupied high-speed rail line cells, and determining that a first preset sub-condition is met if the ratio of the occupied high-speed rail line cells is greater than a first threshold value;

satisfying the second preset sub-condition comprises: and calculating a first moving distance and a first moving speed of the user terminal according to the occupied cell list information and the high-speed railway line cell list information and a preset rule, and determining that a second preset sub-condition is met if the first moving distance is greater than a distance threshold and the first moving speed is greater than a speed threshold and the moving direction of the user terminal is judged to be the same as the high-speed railway line direction information.

Specifically, after acquiring the high-speed rail line cell list information of the high-speed rail line to be tested and the occupied cell list information of the user terminal, analyzing the high-speed rail line cell list information and the occupied cell list information, judging whether the following two preset sub-conditions are met simultaneously, if so, determining that the user terminal meets the preset conditions, and taking the user terminal as a target user terminal.

Wherein judging whether the first preset sub-condition is met comprises: according to the network cell number of the network cell in the occupied cell list information and the high-speed rail cell number of the high-speed rail line cell in the high-speed rail line cell list information of the high-speed rail line to be tested, a first number of the high-speed rail line cells in the high-speed rail line cell list information of the high-speed rail line to be tested in the occupied cell list information is obtained, then the total number of the high-speed rail line cells in the high-speed rail line cell list information is obtained, and the ratio of the first number to the total number is used as the occupied high-speed rail line cell ratio. And judging whether the calculated occupied cell ratio is greater than a first threshold value, if so, determining that a first preset sub-condition is met, otherwise, determining that the user terminal does not meet the first preset sub-condition. For example: setting parameters for identifying cell names in the network cell numbers and the high-speed rail cell numbers, if the parameters for identifying the cell names in the network cell numbers of 80 network cells in the occupied cell list information of the user terminal A are the same as the parameters for identifying the cell names in the high-speed rail cell numbers of the high-speed rail line cells in the high-speed rail line cell list information of the high-speed rail line B to be tested, namely the first number of the high-speed rail line cells occupied by the user terminal A on the high-speed rail line B to be tested is 80. If the total number of the high-speed railway cells in the high-speed railway cell list information of the high-speed railway B to be tested is 100, the occupied cell ratio is 80/100 is 0.8. Assuming that the first threshold is 0.7, it is determined that 0.8>0.7, that is, the occupied cell ratio of the user terminal a is greater than the first threshold, and it is determined that the user terminal a satisfies the first preset sub-condition.

Wherein judging whether the second preset sub-condition is met comprises: according to the occupied cell list information of the user terminal and the high-speed rail line cell list information of the high-speed rail line to be tested, calculating a first moving distance and a first moving speed of the user terminal according to a preset rule, and if the calculated first moving distance is judged to be larger than a distance threshold value and the first moving speed is judged to be larger than a speed threshold value, and the moving direction of the user terminal is judged to be the same as the high-speed rail line direction information of the high-speed rail line cell list information of the high-speed rail line to be tested, determining that the user terminal meets a second preset sub-condition. Because the moving speed can affect the effect of network testing, the larger the moving speed is, the larger the influence on the network service quality is, the more easily the problems of the wireless network can be displayed, and the testing personnel can evaluate, optimize and maintain the network quality. In addition, the traveling speed of the high-speed rail is generally high, and therefore the moving speed of the corresponding user terminal is also high. In order to make the test result more accurate, the embodiment of the invention calculates the first moving distance and the first moving speed of the user terminal, and compares the calculated first moving distance and the calculated first moving speed with the preset distance threshold and speed threshold respectively, so that the screened user terminal is more reasonable. The speed threshold and the distance threshold may be set according to an actual condition of the high-speed rail running of the high-speed rail line to be tested, for example, the speed threshold is set as an average speed of the high-speed rail running in the high-speed rail line to be tested, the distance threshold may be set to be less than or equal to the length of the high-speed rail line to be tested, and of course, other values may also be set according to the actual condition.

According to the method for acquiring the high-speed rail simulation drive test data, whether the user terminal meets a first preset sub-condition and a second preset sub-condition at the same time is judged according to the list information of the occupied high-speed rail line cells of the user terminal and the list information of the high-speed rail line cells of the high-speed rail to be tested, if yes, the user terminal is determined to be a target user terminal, and the communication data of the target user terminal is used as the drive test data to perform network evaluation, optimization and maintenance on the high-speed rail to be tested. The accuracy of the high-speed rail simulation drive test data is improved, and the resource demand of the high-speed rail simulation drive test, such as human resource demand and equipment resource demand, is reduced.

On the basis of the foregoing embodiment, the calculating a first moving distance and a first moving speed of the user terminal according to a preset rule includes:

according to the occupied cell list information and the high-speed rail line cell list information, acquiring a starting high-speed rail cell and a corresponding first starting time of the user terminal on the high-speed rail to be tested, and terminating the high-speed rail cell and a corresponding first terminating time;

calculating a first moving distance of the user terminal according to the starting high-speed rail cell and the ending high-speed rail cell;

calculating a first moving time of the user terminal on the high-speed railway to be tested according to the first starting time and the first termination time;

and taking the ratio of the first moving distance to the first moving time as the first moving speed.

Specifically, according to the network cell number and the time when the user terminal occupies the network cell in the occupied cell list information of the user terminal, and the high-speed rail cell number in the high-speed rail line cell list information of the high-speed rail line to be tested, the start high-speed rail cell C1 and the corresponding first start time TS1 of the user terminal on the high-speed rail line to be tested, and the end high-speed rail cell C2 and the corresponding first end time TS2 of the user terminal on the high-speed rail line to be tested are obtained. Calculating a first moving distance S of the user terminal according to the longitude and latitude coordinates of the base station where the starting high-speed rail cell C1 is located and the longitude and latitude coordinates of the base station where the ending high-speed rail cell C2 is located, calculating a first moving time T of the user terminal on the high-speed rail to be tested according to the first starting time TS1 and the first ending time TS2, taking the ratio of the first moving distance S to the first moving time T as a first moving speed V of the user terminal, namely V is S/T, and then judging whether the calculated first moving distance is greater than a distance threshold value or not and whether the first moving speed is greater than a speed threshold value or not. The method for calculating the first moving distance of the user terminal may also adopt other manners, such as calculating by using the longitude and latitude coordinates of the geometric center of the starting high-speed rail cell C1 and the longitude and latitude coordinates of the geometric center of the terminating high-speed rail cell C2, or other methods, which is not limited in the embodiment of the present invention.

The method for acquiring the high-speed rail simulation drive test data provided by the embodiment of the invention calculates the first moving distance and the first moving time of the user terminal on the high-speed rail to be tested and the first moving speed of the user terminal on the high-speed rail to be tested, and screens out the user terminal meeting the requirements according to the calculated first moving distance and the first moving speed. The acquisition of the high-speed rail simulation drive test data is more reasonable and accurate, the identified high-speed rail user is more accurate, the accuracy of the high-speed rail simulation drive test result is improved, and the resources required by the traditional high-speed rail test are saved.

On the basis of the above embodiment, the method further includes: sequentially numbering the high-speed rail line cells in the high-speed rail line to be tested according to the direction information of the high-speed rail line from small to large to obtain the high-speed rail cell numbers of the high-speed rail line cells;

correspondingly, the determining that the moving direction of the user terminal is the same as the high-speed rail line direction information includes:

and acquiring a first high-speed rail cell number corresponding to the initial high-speed rail cell and a second high-speed rail cell number corresponding to the terminal high-speed rail cell, calculating a difference value between the first high-speed rail cell number and the second high-speed rail cell number, and if the difference value is smaller than zero, determining that the moving direction of the user terminal is the same as the high-speed rail line direction information.

Specifically, when the list information of the high-speed rail line cells of the high-speed rail line to be tested is established, the high-speed rail line cells with longitude and latitude information along the way are sequentially input according to one direction, namely according to the direction information of the high-speed rail line, and all the high-speed rail new line cells are numbered according to the sequence from small to large. Namely, each high-speed rail line cell corresponds to a high-speed rail line cell number, and partial parameters in the high-speed rail line cell numbers are numbered from small to large in sequence along one direction according to the position of the high-speed rail line cell on a high-speed rail line to be tested. And acquiring an initial high-speed rail cell and an initial high-speed rail cell of the user terminal according to the occupied cell list information of the user terminal and the high-speed rail line cell list information of the high-speed rail line to be tested. And respectively acquiring a first high-speed rail cell number corresponding to the initial high-speed rail cell and a second high-speed rail cell number corresponding to the termination high-speed rail cell according to the high-speed rail cell number in the high-speed rail line cell list information of the high-speed rail line to be tested. And calculating the difference value between the first high-speed rail cell number and the second high-speed rail cell number, if the obtained difference value is less than zero, namely the initial high-speed rail cell number is less than the termination cell number, and indicating that the initial high-speed rail cell of the information user terminal is before the termination of the high-speed rail cell along the high-speed rail line direction of the high-speed rail line to be tested. That is, the user terminal is considered to move along the direction information of the high-speed rail defined in the cell list information of the high-speed rail to be tested, and the moving direction of the user terminal is determined to be the same as the direction information of the high-speed rail to be tested.

In addition, other methods may also be employed to determine the moving direction of the user terminal, such as: judging the distance between the starting high-speed rail cell and the first high-speed rail line cell in the high-speed rail line cell list information of the high-speed rail line to be tested and the distance between the ending high-speed rail cell and the first high-speed rail line cell, comparing the two distances, namely judging the distance between the starting high-speed rail cell and the ending high-speed rail cell and the starting point of the high-speed rail line to be tested, further judging whether the user terminal is along the starting point far away from the high-speed rail line to be tested or close to the starting point of the high-speed rail line to be tested, and if the user terminal is far away from the starting point, determining that the moving direction of the user terminal is the same as the high-speed rail line direction information of the high-speed rail line to be tested. Of course, whether the moving direction of the user terminal is the same as the high-speed rail line direction information of the high-speed rail line to be tested may also be determined according to the method, and the embodiment of the present invention is not particularly limited.

According to the method for acquiring the high-speed rail simulation drive test data, provided by the embodiment of the invention, according to the number of a first high-speed rail cell of an initial high-speed rail cell and the number of a second high-speed rail cell of a terminal high-speed rail cell of a user terminal on a high-speed rail to be tested, the user terminal with the moving direction being the same as the high-speed rail line defined by the high-speed rail to be tested is acquired and used as an alternative target user terminal. The acquisition of the high-speed rail simulation drive test data is more reasonable and accurate, the accuracy of the high-speed rail simulation drive test result is improved, and resources required by the traditional high-speed rail test are saved.

On the basis of the above embodiment, the method further includes: if the high-speed line to be tested is judged and known to have the high-speed line with the network coverage overlapping degree larger than the preset threshold, acquiring high-speed line cell list information of the high-speed line, wherein the high-speed line cell list information comprises a high-speed network cell number corresponding to the high-speed line;

correspondingly, the determining whether the user terminal meets the preset condition further includes: simultaneously satisfying a third preset sub-condition, wherein satisfying the third preset sub-condition comprises:

acquiring an initial high-speed cell and a corresponding second initial time of the user terminal on the high-speed line according to the occupied cell list information and the high-speed line cell list information, and terminating the high-speed cell and the corresponding second termination time;

calculating a second moving distance of the user terminal according to the starting high-speed cell and the terminating high-speed cell, calculating a second moving time of the user terminal according to the second starting time and the second terminating time, and taking the ratio of the second moving distance to the second moving time as the second moving speed;

if the second moving distance is judged to be larger than the distance threshold and the second moving speed is judged to be larger than the speed threshold, acquiring a second number of the high-speed network cells of the occupied cell list information belonging to the high-speed line cell list information, and taking a ratio of the second number to a third number as a ratio of the occupied high-speed cells, wherein the third number is the sum of the first number and the second number, and if the ratio of the high-speed cells is smaller than the second threshold, determining that a third preset sub-condition is met.

Specifically, because some high-speed railway lines to be tested are built with high-speed railway lines, when an expressway which is consistent with the direction of the high-speed railway line to be tested or partially consistent with the direction of the high-speed railway line to be tested and has coverage overlapping with the high-speed railway line to be tested in the meaning of a mobile network exists, namely when the signal coverage overlapping degree of a private network of the high-speed railway line to be tested and a public network corresponding to the high-speed railway line is greater than a preset threshold value, some high-speed users can be switched to the private network of the high-speed railway line under some conditions. This may cause some user terminals moving at a high speed to be erroneously identified as high-speed rail user terminals, which may cause inaccurate identification of the target user terminal of the high-speed rail simulation drive test, and further cause inaccurate high-speed rail simulation drive test. In the embodiment of the invention, when the high-speed line with the network coverage overlapping degree larger than the preset threshold value exists in the high-speed railway to be tested, the high-speed line cell list information of the high-speed line is obtained, wherein the high-speed line cell list information comprises the high-speed network cell number corresponding to the high-speed line. Then, according to the acquired list information of the high-speed line cells, the list information of the occupied cells of the user terminal and the list information of the high-speed line cells of the high-speed rail to be tested, the user terminal moving at a high speed is deleted, that is, whether the user terminal meets a third preset sub-condition is judged, and the specific method comprises the following steps:

acquiring occupied cell list information of the user terminal meeting the first preset sub-condition and the second preset sub-condition, acquiring a starting high-speed cell c1 and a corresponding second starting time ts1 of the user terminal on a high-speed line according to the occupied cell list information and the acquired high-speed line cell list information, and terminating the high-speed cell c2 and the corresponding second terminating time ts 2. Specifically, the starting high speed cell and the terminating high speed cell may be obtained by referring to a method for obtaining the starting high speed cell and the terminating high speed cell, which is not described herein again. And calculating a second moving distance s of the user terminal according to the longitude and latitude coordinates of the base station where the starting high-speed cell c1 is located and the longitude and latitude coordinates of the base station where the ending high-speed cell c2 is located, calculating a second moving time t of the user terminal on the high-speed railway to be tested according to a second starting time ts1 and a second ending time ts2, taking the ratio of the second moving distance s to the second moving time t as a second moving speed v of the user terminal, namely v is s/t, and then judging whether the calculated second moving distance is greater than a distance threshold or not and whether the second moving speed is greater than a speed threshold or not. And if the calculated second moving distance of the user terminal is greater than the distance threshold and the second moving speed is greater than the speed threshold, the user terminal is considered as a possible high-speed user terminal. And then acquiring a second number y of the high-speed network cells of which the occupied cell list information belongs to the high-speed line cell list information and a first number x of the high-speed line cells occupied by the user terminal, taking the sum of the first number x and the second number y as a third number z, and calculating the ratio of the second number y to the third number z, namely the ratio of the occupied high-speed cells W to y/z to y/(x + y). And if the calculated high-speed cell ratio is greater than the second threshold value, determining that the user terminal is a high-speed user terminal and deleting the user terminal.
