本发明涉及网络领域，具体涉及一种识别高铁上终端设备的方法及装置。The invention relates to the field of networks, in particular to a method and device for identifying terminal equipment on a high-speed rail.
背景技术Background technique
截至2018年9月，中国已完成2.8万公里的高铁建设，2019年新建4200公里，预计2025年总长度将超过3.8万公里。移动运营商认为高铁上的用户是高价值用户，需要重点保证高铁上用户的用户体验。所以，针对高铁建立专门高铁专网，让高铁用户专享高铁专网以提供好的速率体验。As of September 2018, China has completed the construction of 28,000 kilometers of high-speed rail, with 4,200 kilometers newly built in 2019, and the total length is expected to exceed 38,000 kilometers in 2025. Mobile operators believe that users on high-speed rail are high-value users and need to focus on ensuring the user experience of users on high-speed rail. Therefore, a special high-speed rail network is established for high-speed rail, so that high-speed rail users can enjoy the high-speed rail private network to provide a good speed experience.
而在实际实施过程中，不是高铁上的用户也会接入高铁专网小区，特别是城区内高铁附近人口密度较大时，会有大量不是高铁上的用户接入高铁专网小区，这样会导致高铁专网小区拥挤，从而无法保证高铁上用户的用户体验，而基站无法识别哪些是高铁用户，哪些不是高铁用户。此外，高铁上的用户也很容易切换到非高铁专网的小区上，这样可能会导致频繁切换，从而也对于高铁上用户的用户体验造成影响。In the actual implementation process, users who are not on the high-speed rail will also access the high-speed rail private network community, especially when the population density near the high-speed rail in the urban area is large, a large number of users who are not on the high-speed rail will access the high-speed rail private network community. As a result, the high-speed rail private network cells are crowded, so that the user experience of users on the high-speed rail cannot be guaranteed, and the base station cannot identify which are high-speed rail users and which are not high-speed rail users. In addition, users on the high-speed rail can easily switch to a non-high-speed rail private network, which may lead to frequent handovers, which also affects the user experience of users on the high-speed rail.
现有基站中有一些识别算法来识别高铁用户，用以控制高铁上的终端设备留在高铁专网的小区中，避免不在高铁上的用户接入高铁专网的小区，尽可能的保证高铁用户的用户体验。而当前基站识别高铁上终端设备的方法主要包括：根据终端设备的移动速度、频偏测量或者切换频度来识别，这些方法由于不能获取终端的准确位置和位移，误差很大，导致识别的准确率很差。There are some identification algorithms in the existing base stations to identify high-speed rail users, to control the terminal equipment on the high-speed rail to stay in the high-speed rail private network cell, to prevent users not on the high-speed rail from accessing the high-speed rail private network cell, and to ensure the high-speed rail users as much as possible. user experience. The current methods for identifying terminal equipment on high-speed railways by base stations mainly include: identifying according to the moving speed of the terminal equipment, frequency offset measurement or switching frequency. These methods cannot obtain the accurate position and displacement of the terminal, and the errors are large, resulting in accurate identification. rate is poor.
发明内容SUMMARY OF THE INVENTION

The method includes: acquiring the number of movement events of the terminal equipment in a unit time, where the movement events include handover events, measurement reporting events, data transmission events, Information change events related to the connection between the base station and the terminal equipment; when the number of mobile events of the terminal equipment per unit time is greater than or equal to the first threshold, it is determined that a high-speed rail handover event occurs; when it is determined that a high-speed rail handover event occurs, the terminal that has been handed over is updated. The count value of the number of high-speed rail switching events of the device; when it is determined that the count value of the high-speed rail switching event times of the terminal equipment where the high-speed rail switching event occurs is greater than or equal to the second threshold value, it is determined that the terminal device that occurs the high-speed rail switching event is a terminal on the high-speed rail. equipment.
本方案不采用移动速度评估，不采用频偏检测，也不采用切换频度计算。根据高铁固有的特点“用户集中”事件来确定发生高铁切换事件。当单位时间内终端设备的移动事件次数大于或等于第一门限值时，相当于“一大群终端设备”在短时间内网络环境集中发生变化。比如，在短时间内发生集中切换事件，则可以确定高铁发生切换事件。该高铁切换事件可以为高铁离开原先基站管理的区域，或进入下一个基站管理的区域，或位于某个小区内。当发生高铁切换事件时，若发生高铁切换事件的终端设备发生高铁切换事件的次数计数值大于或等于第二门限值时，可以确定该终端设备为高铁上的终端设备。采用这种方式识别高铁上的终端设备误差较低，可以提高识别的准确率。This scheme does not use moving speed evaluation, frequency offset detection, and switching frequency calculation. According to the inherent characteristics of high-speed rail "user concentration" event to determine the occurrence of high-speed rail switching events. When the number of movement events of the terminal equipment in a unit time is greater than or equal to the first threshold value, it is equivalent to that "a large group of terminal equipments" collectively changes the network environment in a short period of time. For example, if a centralized handover event occurs in a short period of time, it can be determined that a handover event occurs in the high-speed rail. The high-speed rail handover event may be that the high-speed rail leaves the area managed by the original base station, or enters the area managed by the next base station, or is located in a certain cell. When a high-speed rail handover event occurs, if the count value of the number of times the high-speed rail handover event occurs in the terminal device where the high-speed rail handover event occurs is greater than or equal to the second threshold value, it can be determined that the terminal device is a terminal device on the high-speed rail.

在一些实施方式中，可以通过多种方法评估终端设备的移动速度，然后将终端设备的移动速度与高铁的移动速度作比较，进而识别终端设备是否为高铁上的终端设备。其中，最准确的方法是通过终端多次上报的经纬度位置信息来估计速度，但这种上报用户经纬度数据的方法涉及用户隐私，通常不能用。还有利用无线信号特征来估算位置的方法，包括小区天线所在的经纬度等位置变化与变化时长的关系来估算移动速度等，这些方法对于终端设备的移动速度估计值都有很大误差，从而导致高铁上的终端设备的识别不准确。In some embodiments, the moving speed of the terminal device can be evaluated by various methods, and then the moving speed of the terminal device can be compared with the moving speed of the high-speed rail, so as to identify whether the terminal device is a terminal device on the high-speed rail. Among them, the most accurate method is to estimate the speed by using the latitude and longitude position information reported by the terminal multiple times, but this method of reporting the user's latitude and longitude data involves user privacy and is usually not applicable. There are also methods for estimating the position by using the characteristics of the wireless signal, including the relationship between the longitude and latitude of the cell antenna and the relationship between the position change and the change time to estimate the moving speed. The identification of terminal equipment on high-speed rail is not accurate.
请参见图1，图1为一种通过频偏测量识别高铁上终端设备的场景图，在该场景中，通过频偏大小估计移动速度，若终端设备移动速度与高铁运行速度一致，则可以认为该终端设备位高铁上的终端设备。通常朝基站天线方向移动的速度越快，频偏越大，但是移动方向与天线方向不一致时，会存在偏差，而且移动方向和天线方向的夹角越大，偏差会越大。在多径或折射径为主的城区，应用该种方法估计移动速度的误差很大。从而识别高铁上的移动终端也会存在很大的误差。Please refer to Figure 1. Figure 1 is a scene diagram of identifying terminal equipment on a high-speed rail through frequency offset measurement. In this scenario, the moving speed is estimated by the magnitude of the frequency offset. If the moving speed of the terminal equipment is consistent with the running speed of the high-speed rail, it can be considered that The terminal equipment is the terminal equipment on the high-speed rail. Usually, the faster the moving speed towards the base station antenna, the greater the frequency offset, but when the moving direction is inconsistent with the antenna direction, there will be a deviation, and the greater the angle between the moving direction and the antenna direction, the greater the deviation will be. In urban areas dominated by multipath or refraction path, the error of using this method to estimate the moving speed is very large. Therefore, there will also be a large error in identifying the mobile terminal on the high-speed rail.
请参见图2，图2为一种通过切换频度识别高铁上移动终端的场景图，在该场景中，通过站间切换计算速度的方法来识别高铁上的终端设备。该方案中认为高铁用户移动速度快，所以切换频度大，通过设置切换频度门限来判断是否为高铁上的终端设备。例如图2中高铁上的终端设备需要很快的在cell1至cell5之间去切换，切换频率很高。但实际上终端设备切换频率和移动速度没有相关性，即使是一个静止的用户也可能在多个小区之间乒乓切换，其切换频度也可能满足要求而被误判为高铁上的终端设备。这样准确率低、误检率高。而且用这种方法判断时延比较大，等判断出来的时候，可能终端设备已经离开了这个区域。Please refer to FIG. 2. FIG. 2 is a scene diagram of identifying a mobile terminal on a high-speed rail by switching frequency. In this scenario, a terminal device on a high-speed rail is identified by switching between stations to calculate the speed. In this scheme, it is considered that high-speed rail users move fast, so the switching frequency is large, and whether it is a terminal device on the high-speed rail is determined by setting a switching frequency threshold. For example, the terminal equipment on the high-speed rail in FIG. 2 needs to switch quickly between cell1 and cell5, and the switching frequency is very high. But in fact, there is no correlation between the switching frequency of terminal equipment and the moving speed. Even a stationary user may ping-pong switch between multiple cells, and the switching frequency may meet the requirements and be misjudged as a terminal equipment on the high-speed rail. This has low accuracy and high false detection rate. Moreover, it is judged that the delay is relatively large by this method. When the judgment is made, the terminal equipment may have left this area.
以上所述的方法误差都比较大，导致识别高铁上终端设备的效果比较差。因此本申请实施例一提供了一种识别高铁上终端设备的方法。该方法主要适用于无线移动通信系统，包括通用移动通信系统(universal mobile telecommunications system，UMTS)，长期演进(long term evolution，LTE)，第五代移动通信(fifth generation communication，5G)，无线局域网(wireless fidelity，WIFI)。当无线移动通信系统覆盖高速铁路、普通铁路或轮船航线、渡口等人多且同时定向移动的场景时，都可用本申请提供的方法进行移动终端设备的识别。请参见图3，该方法包括：The errors of the above-mentioned methods are relatively large, resulting in a poor effect of identifying the terminal equipment on the high-speed rail. Therefore,
101.获取单位时间内终端设备的移动事件次数。101. Acquire the number of movement events of the terminal device within a unit time.
获取单位时间内终端设备的移动事件次数。覆盖高铁的基站实时计算“移动事件密度”，该移动事件包括但不限于切换事件、测量上报事件、数据传输事件、基站与终端设备连接相关的信息变化事件，还可以为一切可以表示终端设备网络环境发生变化的事件，上述举例不能作为本申请的限制。该“移动事件密度”为单位时间内终端设备的移动事件次数。Get the number of movement events of the terminal device within a unit time. The base station covering the high-speed rail calculates the "mobile event density" in real time. The mobile event includes but is not limited to handover events, measurement reporting events, data transmission events, and information change events related to the connection between the base station and the terminal device. It can also be everything that can represent the terminal device network. In the event of changes in the environment, the above examples cannot be used as limitations of this application. The "mobile event density" is the number of mobile events of the terminal device per unit time.
示例性的，若该移动事件为切换事件，则该单位时间内终端设备的移动时间次数即为单位时间内终端设备的切换次数。该切换次数可以为切换入的次数、切换出的次数或者切换入的次数加上切换出的次数中的任意一种。该基站可以在时间轴上以滑窗机制或跳窗机制统计当前时间窗的切换入次数和/或切换出次数。根据当前时间窗的切换次数以及时间窗的时长获取单位时间内终端设备的切换次数。具体的，可以用当前时间窗的切换次数除以时间窗的时长从而获得单位时间内终端设备的切换次数。该单位时间内终端设备的切换次数可以代表当前的“切换事件密度”。若单位时间内切换次数比较高，说明发生终端设备集中切换。Exemplarily, if the movement event is a handover event, the number of times of movement of the terminal device within the unit time is the number of times of handover of the terminal device within the unit time. The number of times of switching may be any one of the number of times of switching in, the number of times of switching out, or the number of times of switching in plus the number of times of switching out. The base station may use a sliding window mechanism or a window jumping mechanism on the time axis to count the number of times of handovers and/or times of handovers in the current time window. According to the switching times of the current time window and the duration of the time window, the switching times of the terminal device per unit time are obtained. Specifically, the switching times of the terminal device per unit time may be obtained by dividing the switching times of the current time window by the duration of the time window. The switching times of the terminal device within the unit time may represent the current "handover event density". If the number of handovers per unit time is relatively high, it means that centralized handover of terminal equipment occurs.
需说明的是，该时间窗的大小，需要根据无线网络覆盖的切换区域大小以及高铁移动速度调整，可以调整为一个合适的值，粗略等于切换区域长度除以高铁移动速度。It should be noted that the size of the time window needs to be adjusted according to the size of the handover area covered by the wireless network and the moving speed of the high-speed rail. It can be adjusted to an appropriate value, which is roughly equal to the length of the handover area divided by the moving speed of the high-speed rail.
步骤101可以为基站执行获取单位时间内的终端设备的移动事件次数；或者基站在获取到单位时间内的终端设备的切换次数之后，将终端设备的移动事件次数发送给控制器。由控制器确定该单位时间内的终端设备的移动事件次数是否超过门限值。Step 101 may be performed for the base station to acquire the number of mobile events of the terminal equipment within a unit time; or the base station may send the number of mobile events of the terminal equipment to the controller after acquiring the number of handovers of the terminal equipment within a unit time. The controller determines whether the number of movement events of the terminal equipment in the unit time exceeds the threshold value.
102.当单位时间内终端设备的移动事件次数大于或等于第一门限值时，确定发生高铁切换事件。102. When the number of movement events of the terminal device per unit time is greater than or equal to the first threshold value, determine that a high-speed rail handover event occurs.
当步骤101中确定的单位时间内终端设备移动事件次数大于或等于第一门限值时，确定发生高铁切换事件。该高铁切换事件可以为高铁离开原先基站管理的区域的事件，或进入下一个基站管理的区域的事件，或在某个时间位于某个小区的事件。When the number of terminal equipment movement events per unit time determined in step 101 is greater than or equal to the first threshold value, it is determined that a high-speed rail handover event occurs. The high-speed rail handover event may be an event in which the high-speed rail leaves the area managed by the original base station, or enters the area managed by the next base station, or is located in a certain cell at a certain time.
需说明的是，若在步骤101中，获取的单位时间内终端设备的移动事件次数可以为切换事件、测量上报事件、数据传输事件、基站与终端设备连接相关的信息变化事件中任意一项或多项事件的次数。在实施过程中，若选取的移动事件不同，该第一门限值的取值也可以相应的作出调整。It should be noted that, if in step 101, the acquired number of movement events of the terminal device per unit time may be any one of handover events, measurement reporting events, data transmission events, information change events related to the connection between the base station and the terminal device, or The number of multiple events. In the implementation process, if the selected mobile events are different, the value of the first threshold value can also be adjusted accordingly.
示例性的，若步骤101中获取的是单位时间内终端设备的切换入次数，在步骤102中可以为确定当单位时间内终端设备的切换入次数大于或等于第一门限值时，确定高铁发生切换入事件；若步骤101中获取的是单位时间内终端设备的切换出次数，在步骤102中可以确定当单位时间内终端设备的切换出次数大于或等于第一门限值时，确定高铁发生切换出事件；若步骤101中获取的是单位时间终端设备的切换入次数与切换出次数之和，在步骤102中可以确定当单位时间内终端设备的切换入次数与切换出次数之和大于或等于第一门限值时，确定高铁发生切换事件；若步骤101中获取的是单位时间内终端设备的测量上报次数，在步骤102中可以确定当单位时间内终端设备的测量上报次数大于或等于第一门限值时，确定高铁发生切换事件；若步骤101中获取的是单位时间内基站与终端设备连接相关信息的变化事件次数，在步骤102中可以确定当单位时间内基站与终端设备连接相关信息的变化事件次数大于或等于第一门限值时，确定高铁发生切换事件。该第一门限值可以为预先设置的静态门限值，也可以为动态门限值，此处不做限制。Exemplarily, if the number of handovers of the terminal device per unit time is obtained in step 101, in step 102, it can be determined that when the number of times of handovers of the terminal device per unit time is greater than or equal to the first threshold value, determine the high-speed rail. A switch-in event occurs; if the number of times of switching out of the terminal device per unit time is obtained in step 101, in step 102, it can be determined that when the number of times of switching out of the terminal device per unit time is greater than or equal to the first threshold value, determine the high-speed rail A switch-out event occurs; if the sum of the switch-in times and the switch-out times of the terminal device per unit time is obtained in step 101, it can be determined in step 102 that the sum of the switch-in times and the switch-out times of the terminal equipment in the unit time is greater than or equal to the first threshold value, it is determined that a handover event occurs in the high-speed rail; if the number of measurement reports of the terminal equipment in a unit time is obtained in step 101, in step 102, it can be determined that the number of times of measurement and reporting of the terminal equipment in a unit time is greater than or equal to When it is equal to the first threshold value, it is determined that a handover event occurs in the high-speed rail; if the number of change events of the information related to the connection between the base station and the terminal equipment in a unit time is obtained in step 101, in step 102, it can be determined that the base station and the terminal equipment in a unit time When the number of change events of the connection-related information is greater than or equal to the first threshold value, it is determined that a handover event occurs in the high-speed rail. The first threshold value may be a preset static threshold value, or may be a dynamic threshold value, which is not limited here.
步骤102可以由基站执行，也可以由控制器执行，若步骤101中，基站将单位时间内的终端设备的移动事件次数发送给控制器，可以由控制器确定单位时间内终端设备的移动事件次数大于或等于第一门限值，从而确定发生高铁切换事件。步骤102也可以直接由基站执行，该基站在获取单位时间内终端设备的移动事件次数之后，确定单位时间内终端设备的移动事件次数大于或等于第一门限值，从而确定发生高铁切换事件。Step 102 can be performed by the base station or by the controller. If in step 101, the base station sends the number of mobile events of the terminal equipment per unit time to the controller, the controller can determine the number of mobile events of the terminal equipment per unit time. It is greater than or equal to the first threshold value, so it is determined that a high-speed rail switching event occurs. Step 102 can also be directly performed by the base station, after obtaining the number of movement events of the terminal device per unit time, the base station determines that the number of movement events of the terminal device per unit time is greater than or equal to the first threshold value, thereby determining that a high-speed rail handover event occurs.
103.当确定发生高铁切换事件时，更新发生高铁切换事件的终端设备的高铁切换事件次数的计数值。103. When it is determined that a high-speed rail switching event occurs, update the count value of the number of high-speed rail switching events of the terminal equipment where the high-speed rail switching event occurs.
当确定发生高铁切换事件时，基站更新发生高铁切换事件的终端设备的高铁切换事件次数的计数值。该终端设备的“高铁切换事件次数的计数值”为该终端设备在发生高铁切换事件时累计发生高铁切换事件的次数的计数值。该高铁切换次数包括终端设备的高铁切换入事件次数、高铁切换出事件次数、测量上报次数、数据传输次数、基站与终端设备连接相关的信息变化事件次数中的至少一项。When it is determined that a high-speed rail handover event occurs, the base station updates the count value of the number of high-speed rail handover events of the terminal equipment where the high-speed rail handover event occurs. The "count value of the number of high-speed rail handover events" of the terminal device is the count value of the number of times the high-speed rail handover event occurs cumulatively by the terminal device when the high-speed rail handover event occurs. The number of high-speed rail handovers includes at least one of the number of high-speed rail handover events of the terminal device, the number of high-speed rail handover events, the number of measurement reports, the number of data transmissions, and the number of information change events related to the connection between the base station and the terminal device.
示例性的，若用户携带的终端设备在高铁上经历了两次高铁切换事件，且在该两次高铁切换事件时，该终端设备都发生了高铁切换事件，则该终端设备的高铁切换事件次数的计数值为2。Exemplarily, if the terminal equipment carried by the user has experienced two high-speed rail switching events on the high-speed rail, and during the two high-speed rail switching events, the terminal equipment has a high-speed rail switching event, the number of high-speed rail switching events of the terminal equipment. The count value is 2.
需说明的是，基站可以在更新发生高铁切换事件的终端设备切换次数的计数值之前，从上游基站接收终端设备的标识与高铁切换事件次数的计数值之间的对应关系。具体的，该对应关系可以为终端设备的标识和高铁切换事件次数的计数值的一个表格。It should be noted that the base station may receive from the upstream base station the correspondence between the identifier of the terminal equipment and the count value of the number of high-speed rail handover events before updating the count value of the number of handover times of the terminal equipment in which the HSR handover event occurs. Specifically, the corresponding relationship may be a table of the identifier of the terminal device and the count value of the number of high-speed rail handover events.
以下表格仅以高铁切换入事件次数计数值和高铁切换出事件次数作为高铁切换事件次数计数值为例，但并不能作为本申请的限制。请参见下表，The following table only takes the count value of the number of high-speed rail handover events and the number of high-speed rail handover events as the count value of the number of high-speed rail handover events, but it cannot be regarded as a limitation of this application. See the table below,
可以理解的是，上述表格统计了高铁切换入事件次数计数值和高铁切换出事件次数计数值，在实际实施过程中，可以只统计高铁切换入事件次数计数值或者只统计高铁切换出事件次数值，也可以统计高铁切换入事件次数计数值与高铁切换出时间次数计数值之和,也可统计测量上报次数、数据传输次数、基站与终端连接相关信息的变化事件次数中的任意一项或几项。此处并不应该理解为对本申请的限制。It can be understood that the above table counts the count value of the number of high-speed rail handover events and the count value of the number of high-speed rail handover events. In the actual implementation process, only the count value of the number of high-speed rail switch-in events or only the number of high-speed rail switch-out events can be counted. , it can also count the sum of the count value of the number of high-speed rail switch-in events and the count value of the high-speed rail switch-out time, or count the number of measurement reports, the number of data transmissions, and the number of changes in the connection information between the base station and the terminal. Any one or several of the events. item. This should not be construed as a limitation of the present application.
基站在确定发生高铁切换事件时，可以更新上述表格。具体的，若该表格中不包含某个终端设备的标识对应的条目，基站检测到该终端设备发生高铁切换入事件了，则在该表格中添加该终端设备的标识并将高铁切换入事件次数的计数值记为1。这样可以考虑到高铁行驶中途可能会有乘客上车，上游基站没有检测到该乘客携带的终端设备，此时可以添加进去。When the base station determines that a high-speed rail handover event occurs, the above table may be updated. Specifically, if the table does not contain an entry corresponding to the identifier of a certain terminal device, and the base station detects that the terminal device has a high-speed rail handover event, it adds the terminal device's identifier to the table and the number of high-speed rail switch-in events. The count value is recorded as 1. In this way, it can be considered that passengers may get on the train in the middle of the high-speed train, and the terminal equipment carried by the passenger is not detected by the upstream base station, and can be added at this time.
若表格中已经包含了某个终端设备的标识对应的条目，基站检测到该终端设备发生高铁切换入事件，则在表格中原先的高铁切换入事件次数的计数值上加1。上述示例仅为举例，并不能作为本申请的限制。If the table already contains an entry corresponding to the identifier of a terminal device, and the base station detects that the terminal device has a high-speed rail handover event, it adds 1 to the original count value of the high-speed rail handover event times in the table. The above examples are only examples and should not be taken as limitations of the present application.
需说明的是，步骤103可以由基站直接执行。若步骤102中，是控制器确定发生高铁切换事件，则步骤104可以为基站采集到发生高铁切换事件的终端设备的标识与高铁切换事件次数之后，将该终端设备的标识与切换次数发送给控制器，由控制器完成更新发生高铁切换事件的终端设备的高铁切换次数的计数值。It should be noted that step 103 may be directly performed by the base station. If, in step 102, the controller determines that a high-speed rail handover event occurs, then step 104 may be that after the base station collects the identifier of the terminal device where the high-speed rail handover event occurs and the number of high-speed rail handover events, the terminal device's identifier and the number of handovers are sent to the controller. The controller completes updating the count value of the high-speed rail switching times of the terminal equipment where the high-speed rail switching event occurs.
104.当确定发生高铁切换事件的终端设备发生高铁切换事件次数的计数值大于或等于第二门限值时，确定所述发生高铁切换事件的终端设备为高铁上的终端设备。104. When it is determined that the count value of the number of times the high-speed rail switching event occurs in the terminal device where the high-speed rail switching event occurs is greater than or equal to the second threshold value, determine that the terminal device where the high-speed rail switching event occurs is a terminal device on the high-speed rail.
当确定发生高铁切换事件的终端设备发生高铁切换事件次数的计数值大于或等于第二门限值时，确定发生高铁切换事件的终端设备为高铁上的终端设备。如步骤103所述，该发生高铁切换事件的终端设备发生高铁切换事件次数的计数值可以包括高铁切换入事件次数的计数值、高铁切换出事件次数、测量上报次数、数据传输次数、基站与终端设备连接相关信息的变化事件次数中任意一项或多项的计数值。When it is determined that the count value of the number of times the high-speed rail switching event occurs in the terminal device where the high-speed rail switching event occurs is greater than or equal to the second threshold value, it is determined that the terminal device where the high-speed rail switching event occurs is the terminal device on the high-speed rail. As described in step 103, the count value of the number of high-speed rail handover events of the terminal equipment in which the high-speed rail handover event occurs may include the count value of the number of high-speed rail handover events, the number of high-speed rail handover events, the number of measurement reports, the number of data transmissions, the number of base stations and terminals The count value of any one or more of the change events of device connection related information.
需说明的是，该第二门限值可以为预先设置的静态门限值或者动态门限值。并且在高铁沿线过程中，针对每个基站的第二门限值可能不相同，此处不做限制。It should be noted that the second threshold value may be a preset static threshold value or a dynamic threshold value. And in the process along the high-speed rail line, the second threshold value for each base station may be different, which is not limited here.
步骤104可以由基站执行。若步骤103中，控制器确定发生高铁切换事件的终端设备发生高铁切换事件次数的计数值大于或等于第二门限值时，也可以由控制器确定所述发生高铁切换事件的终端设备为高铁上的终端设备。Step 104 may be performed by the base station. If, in step 103, the controller determines that the count value of the number of high-speed rail switching events of the terminal equipment in which the high-speed rail switching event occurs is greater than or equal to the second threshold value, the controller may also determine that the terminal equipment in which the high-speed rail switching event occurs is the high-speed rail. on the terminal device.
需说明的是，若步骤104为基站执行，在基站确定所述发生高铁切换事件的终端设备为高铁上的终端设备之后，该基站还可以将本地终端设备的标识与高铁切换事件次数的计数值之间的对应关系发送给下游基站，并删除本地存储的终端设备的标识与高铁切换事件次数的计数值之间的对应关系。It should be noted that, if step 104 is performed by the base station, after the base station determines that the terminal equipment in which the high-speed rail handover event occurs is the terminal equipment on the high-speed rail, the base station may also combine the identifier of the local terminal equipment with the count value of the number of high-speed rail handover events. The corresponding relationship between them is sent to the downstream base station, and the corresponding relationship between the locally stored identifier of the terminal device and the count value of the number of high-speed rail handover events is deleted.
本申请可以充分利用用户在同一辆高铁上，终端设备集中、同向、同速度的特征，可以通过在时域上通过确定单位时间内终端设备的移动事件次数大于或等于第一门限值确定终端设备的“移动事件密度”，而实现针对高铁的“群效应”进行判断。当发生高铁切换事件，并且发生高铁切换事件的终端设备的高铁切换事件的计数值大于或等于第二门限值时，可以确定发生高铁切换事件的终端设备为高铁上的终端设备，并把识别出来的高铁用户信息传递给后续小区或基站使用，后续基站可以对高铁用户实施差异化处理，以提升高铁用户体验。这样可以简单、可靠地判断出发生高铁切换中哪些用户为高铁上的终端设备，可以避免现有的各种方案中产生误差的各种原因。This application can make full use of the characteristics of users on the same high-speed rail, the terminal equipment is concentrated, in the same direction, and at the same speed. In the time domain, it can be determined by determining that the number of mobile events of the terminal equipment per unit time is greater than or equal to the first threshold value. The "mobile event density" of the terminal equipment is used to judge the "group effect" of the high-speed rail. When a high-speed rail switching event occurs, and the count value of the high-speed rail switching event of the terminal equipment in which the high-speed rail switching event occurs is greater than or equal to the second threshold value, it can be determined that the terminal equipment in which the high-speed rail switching event occurs is the terminal equipment on the high-speed rail, and the identification The outgoing high-speed rail user information is passed to subsequent cells or base stations for use, and subsequent base stations can perform differentiated processing on high-speed rail users to improve the high-speed rail user experience. In this way, it is possible to simply and reliably determine which users are terminal devices on the high-speed rail during the high-speed rail handover, and to avoid various causes of errors in existing solutions.
同时，在本申请的架构中，还可以设置有控制器，请参见步骤101至步骤104中相应的描述，覆盖高铁及附近的基站实时的把终端设备切换入、切换出的事件信息、测量上报信息、数据传输信息、基站与终端连接相关信息，包括用户标识和事件发生的时间等，发送给控制器，由控制器进行滑窗或跳窗判断并识别，然后由控制器把识别结果或历史数据发送给目标基站；或者由基站进行滑窗或跳窗判断后把统计表格发送给控制器，最终由控制器把识别结果或历史数据发送给目标基站。At the same time, in the architecture of the present application, a controller may also be provided, please refer to the corresponding descriptions in steps 101 to 104, covering the high-speed rail and nearby base stations to switch terminal equipment in and switch out event information, measurement reporting in real time Information, data transmission information, information related to the connection between the base station and the terminal, including user identification and event occurrence time, etc., are sent to the controller, and the controller will perform sliding window or window jumping judgment and identification, and then the controller will identify the results or history. The data is sent to the target base station; or the base station performs sliding window or window jump judgment and sends the statistical table to the controller, and finally the controller sends the identification result or historical data to the target base station.
在架构中加入控制器，在切换事件数据传输上有明显优势。若由源基站发往目的基站，这些目标基站的选择需要提前确定，而且后续还要动态调整，实现机制稍复杂。如果由控制器进行数据集中处理，准确定可以得到提高，在时延上稍大但是影响不大，因为整个对于高铁上终端设备的识别对时间实时性要求在10秒级均可。Adding a controller to the architecture has obvious advantages in switching event data transmission. If it is sent from the source base station to the destination base station, the selection of these target base stations needs to be determined in advance, and the subsequent dynamic adjustment is required, and the implementation mechanism is slightly complicated. If the data is centrally processed by the controller, the accuracy can be improved, and the delay is slightly larger but has little impact, because the entire identification of the terminal equipment on the high-speed rail requires only 10 seconds of real-time time.
