背景技术Background technique

指纹定位是一种利用不同地理位置具有不同无线信号特征的特点,通过特征推测地理位置的定位技术。指纹定位技术一般分为两个阶段:离线建库阶段和在线定位阶段。对于离线建库阶段而言,需要采集待定位区域内所有位置的信号特征,构建信号特征与地理位置之间的映射关系,对于在线定位阶段而言,获取待定位终端的信号特征,并基于预先构建的信号特征与地理位置之间的映射关系计算出待定位终端的位置。Fingerprint positioning is a positioning technology that utilizes the characteristics of different geographic locations with different wireless signal characteristics and infers geographic locations based on the features. Fingerprint positioning technology is generally divided into two stages: offline database building stage and online positioning stage. For the offline database building phase, it is necessary to collect the signal characteristics of all locations in the area to be located, and construct the mapping relationship between the signal characteristics and the geographic location. For the online positioning phase, obtain the signal characteristics of the terminal to be located, and based on the The mapping relationship between the constructed signal feature and the geographic location calculates the location of the terminal to be located.

随着通信技术的发展,出现了各种不同的网络制式,在相关技术中,当需要建立某一网络制式对应的定位指纹库时,就必须在该网络制式下采集相应的信号特征,当该网络制式下的信号特征难以直接采集时,就无法建立该网络制式对应的定位指纹库,更无法对该网络制式下的终端进行定位。With the development of communication technology, various network standards have emerged.

When the signal characteristics under the network standard are difficult to collect directly, the positioning fingerprint database corresponding to the network standard cannot be established, nor can the terminal under the network standard be located.

具体实施方式detailed description

为了使本公开的目的、技术方案及优点更加清楚明白,下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本公开,并不用于限定本公开。In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below through specific implementations in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

为了解决当需要建立某一网络制式对应的定位指纹库时,必须在该网络制式下采集相应的信号特征,导致当该网络制式下的信号特征难以直接采集时,就无法建立该网络制式对应的定位指纹库的问题,本公开实施例提供一种指纹库建立方法。请参见图1所示,根据本公开实施例的指纹库建立方法包括如下步骤S101至S103。In order to solve the problem that when a positioning fingerprint library corresponding to a certain network standard needs to be established, the corresponding signal characteristics must be collected under the network standard, so that when the signal characteristics under the network standard are difficult to directly collect, the corresponding network standard cannot be established. To locate the problem of the fingerprint database, an embodiment of the present disclosure provides a method for establishing a fingerprint database. Referring to FIG. 1, the method for establishing a fingerprint database according to an embodiment of the present disclosure includes the following steps S101 to S103.

在步骤S101,获取第一网络制式下的终端所处位置的位置信息,以及与该位置信息对应的第一网络制式下的第一小区所传输的第一信号的信号特征。In step S101, the location information of the location of the terminal under the first network standard and the signal characteristics of the first signal transmitted by the first cell under the first network standard corresponding to the location information are obtained.

应当说明的是,在一些实施例中,在步骤S101之前,可以从与终端所处的位置对应的第一网络制式下的小区中筛选出与第二网络制式中的第二小区具有相同通信资源的第一小区。本实施例中的通信资源是确定第二小区和第一小区传输第一信号时,该第一信号在空间传播的特性相似的各种通信资源。例如,在一种示例中,该通信资源包括天线资源(即天线)和频段资源,此时,筛选出来的第一小区必然与第二网络制式下的至少一个第二小区具有相同的天线资源,也即采用相同的天线,且利用相同的频段资源进行第一信号的传输。It should be noted that, in some embodiments, before step S101, the cells under the first network standard corresponding to the location of the terminal may be selected to have the same communication resources as the second cell in the second network standard The first cell. The communication resources in this embodiment are various communication resources with similar characteristics of spatial propagation of the first signal when the second cell and the first cell transmit the first signal. For example, in an example, the communication resources include antenna resources (ie, antennas) and frequency band resources. In this case, the selected first cell must have the same antenna resources as at least one second cell under the second network standard. That is, the same antenna is used, and the same frequency band resource is used to transmit the first signal.

本实施例中所提及的与相应位置信息对应的第一网络制式下的第一小区可以包括:终端在相应的位置上传输第一信号时,其当前所在的服务小区和/或为该服务小区的至少一个邻区。The first cell under the first network standard corresponding to the corresponding location information mentioned in this embodiment may include: when the terminal transmits the first signal at the corresponding location, the serving cell where the terminal is currently located and/or serves the service At least one neighboring cell of the cell.

需要说明的是,本实施例中的第一信号包括上行参考信号(当然,应当理解的是,除了上参考信号外,也可以包括其他任意能进行信号特征采集用于建立指纹库的上行信号)和/或下行参考信号(当然,应当理解的是,除了下行参考信号外,也可以包括其他任意能进行信号特征采集用于建立指纹库的下行信号)。本实施例中信号特征可以是任意的可以表明终端与相应基站之间进行信号传输时的路损的数据,包括但不限于是信号接收功率和/或信号时延,且本实施例提供的指纹库建立方法可以应用于服务器上。It should be noted that the first signal in this embodiment includes an uplink reference signal (of course, it should be understood that, in addition to the upper reference signal, any other uplink signal that can be used for signal feature collection to establish a fingerprint database) And/or a downlink reference signal (of course, it should be understood that, in addition to the downlink reference signal, any other downlink signal that can perform signal feature collection to establish a fingerprint database can also be included. The signal feature in this embodiment may be any data that can indicate the path loss during signal transmission between the terminal and the corresponding base station, including but not limited to the signal received power and/or signal delay, and the fingerprint provided in this embodiment The library establishment method can be applied to the server.

在步骤S102,确定第二网络制式中与第一小区具有相同通信资源的第二小区。In step S102, a second cell with the same communication resources as the first cell in the second network standard is determined.

应当理解的是,本实施例中的服务器上可以预先存储第一网络制式下的各基站所对应的各小区的通信资源以及第二网络制式下的各基站所对应的各小区的通信资源,根据这些信息,便可确定出第二网络制式下与第一小区具有相同通信资源的第二小区。也可通过实时的按照上述筛选方式进行筛选获取。It should be understood that the server in this embodiment may pre-store the communication resources of each cell corresponding to each base station under the first network standard and the communication resources of each cell corresponding to each base station under the second network standard, according to With this information, a second cell with the same communication resources as the first cell under the second network standard can be determined. It can also be obtained by real-time screening according to the above screening method.

在一种示例中,当第一信号为下行参考信号时,可以由第一网络制式下的终端直接测量第一网络制式下的第一小区所传输的下行参考信号的信号特征。本实施例中,服务器可以直接接收由终端测量并发送的位置信息和下行参考信号的信号特征,也可以接收由相应的 基站发送的位置信息和下行参考信号的信号特征。此时,终端应当将检测到的位置信息和下行参考信号的信号特征发送给相应的基站。对于此种示例,服务器可以将第一网络制式中的与第二网络制式下的小区具有相同的通信资源的小区的信息发送给各终端,直接对各终端进行提示,这样,第一网络制式下的终端就可以不测量与第二网络制式下的小区不具有相同通信资源的小区所传输的下行参考信号的信号特征,这样,服务器就可以直接接收到需要的位置信息和对应的第一小区所传输的第一信号的信号特征,无需进行信息的筛选。In one example, when the first signal is a downlink reference signal, the terminal under the first network standard may directly measure the signal characteristics of the downlink reference signal transmitted by the first cell under the first network standard. In this embodiment, the server may directly receive the position information and the signal characteristics of the downlink reference signal measured and sent by the terminal, or may receive the position information and the signal characteristics of the downlink reference signal sent by the corresponding base station. At this time, the terminal should send the detected location information and the signal characteristics of the downlink reference signal to the corresponding base station. For this example, the server may send the information of the cell in the first network mode that has the same communication resources as the cell in the second network mode to each terminal, and directly prompt each terminal. In this way, under the first network mode The terminal can not measure the signal characteristics of the downlink reference signal transmitted by the cell that does not have the same communication resources as the cell under the second network standard, so that the server can directly receive the required location information and the corresponding first cell. The signal characteristics of the transmitted first signal do not require information screening.

当第一信号包括上行参考信号时,可以由终端检测位置信息,并将该位置信息发送给相应的基站。基站测量第一小区所传输的上行参考信号的信号特征,服务器可以接收基站发送的位置信息和第一小区所传输的上行参考信号的信号特征。对于此种示例,服务器可以将第一网络制式中的与第二网络制式下的小区具有相同的通信资源的小区的信息发送给各基站,直接对各基站进行提示。这样,第一网络制式下的一些基站就可以不测量与第二网络制式下的小区不具有相同通信资源的小区所传输的上行参考信号的信号特征。这样,服务器照样可以直接接收到需要的位置信息和对应的第一小区所传输的第一信号的信号特征,无需进行信息的筛选。When the first signal includes an uplink reference signal, the terminal may detect the location information and send the location information to the corresponding base station. The base station measures the signal characteristics of the uplink reference signal transmitted by the first cell, and the server can receive the location information sent by the base station and the signal characteristics of the uplink reference signal transmitted by the first cell. For such an example, the server may send the information of the cell in the first network standard that has the same communication resources as the cell in the second network standard to each base station, and directly prompt each base station. In this way, some base stations under the first network system may not measure the signal characteristics of the uplink reference signals transmitted by the cells that do not have the same communication resources as the cells under the second network system. In this way, the server can directly receive the required location information and the signal characteristics of the first signal transmitted by the corresponding first cell without the need for information screening.

在步骤S103,根据第一信号的信号特征,以及第一信号的信号特征对应的位置信息,生成第二网络制式的定位指纹库。In step S103, according to the signal characteristics of the first signal and the location information corresponding to the signal characteristics of the first signal, a positioning fingerprint library of the second network standard is generated.

应当说明的是,在一种示例中,为了提升定位效率,可建立第一小区的第一信号的信号特征与对应的位置信息的关联信息,以生成第二网络制式的定位指纹库。即,直接将第一小区的第一信号的信号特征与对应的位置信息的关联信息作为第二网络制式的定位指纹库。或者为了便于管理,还可以将终端的位置信息与第一小区所传输的第一信号的信号特征的对应关系中的第一小区的标识信息替换成第二小区的标识信息。It should be noted that, in an example, in order to improve the positioning efficiency, the association information between the signal characteristics of the first signal of the first cell and the corresponding location information may be established to generate a positioning fingerprint library of the second network standard. That is, the association information of the signal characteristics of the first signal of the first cell and the corresponding location information is directly used as the positioning fingerprint library of the second network standard. Or for convenience of management, the identification information of the first cell in the correspondence between the location information of the terminal and the signal characteristics of the first signal transmitted by the first cell may also be replaced with the identification information of the second cell.

在另一示例中,为了建立更精确的定位指纹库以便于后续精准定位,还可先以第二网络制式中对应的第一信号的信号特征为基准,对第一网络制式中第一小区对应的第一信号的信号特征进行修正处 理,然后基于修正处理之后的第一信号的信号特征与位置信息建立定位指纹库,其中一种示例的建立过程如下。在本示例中,第一信号的信号特征包括信号接收特征,本示例中的建立定位指纹库的过程包括:获取第一网络制式的第一小区发送第一信号的信号发送特征与第二网络制式的第二小区发送第一信号的信号发送特征的特征差值;根据获取的特征差值对第一小区中所述第一信号的信号接收特征进行修正处理;以及建立修正处理后的第一信号的信号接收特征与对应位置信息的关联关系,生成所述第二网络制式的定位指纹库。In another example, in order to establish a more accurate positioning fingerprint database for subsequent accurate positioning, the signal characteristics of the corresponding first signal in the second network standard may be first used as a reference to correspond to the first cell in the first network standard The signal characteristics of the first signal are corrected, and then a positioning fingerprint database is established based on the signal characteristics and the position information of the first signal after the correction processing. An example of the establishment process is as follows. In this example, the signal characteristics of the first signal include signal reception characteristics, and the process of establishing the positioning fingerprint database in this example includes: acquiring the signal transmission characteristics of the first cell and the second network standard of the first cell that transmits the first signal The second cell sends the first signal, the characteristic difference of the signal transmission characteristics; according to the obtained characteristic difference, corrects the signal reception characteristics of the first signal in the first cell; and establishes the corrected first signal The association relationship between the signal receiving characteristics of and the corresponding location information to generate the positioning fingerprint database of the second network standard.

下面以第一信号为下行参考信号(当然,应当理解的是,除了下行参考信号外,也可以是其他任意能进行信号特征采集用于建立指纹库的下行信号),并且信号接收特征包括信号接收功率为例进行说明。此时,获取的信号发送特征可对应地包括信号发送功率。步骤S103实质上可以包括如图2所示的三个子步骤S21至S23。The following uses the first signal as a downlink reference signal (of course, it should be understood that, in addition to the downlink reference signal, it may be any other downlink signal that can perform signal feature collection to establish a fingerprint database), and the signal reception characteristics include signal reception The power is used as an example. At this time, the acquired signal transmission characteristics may correspondingly include signal transmission power. Step S103 may substantially include three sub-steps S21 to S23 as shown in FIG. 2.

在步骤S21,获取第一小区和第二小区的下行参考信号的信号发射功率的差值。In step S21, the difference between the signal transmission powers of the downlink reference signals of the first cell and the second cell is obtained.

在步骤S22,利用得到的差值对第一小区的下行参考信号的信号接收功率进行修正,例如通过下行参考信号的信号接收功率减去该差值。In step S22, the received difference value is used to correct the signal reception power of the downlink reference signal of the first cell, for example, by subtracting the difference value from the signal reception power of the downlink reference signal.

在步骤S23,根据修正后的结果,建立位置信息与修正后下行参考信号的信号接收功率的关联关系(也即对应关系)。In step S23, according to the corrected result, an association relationship (that is, a correspondence relationship) between the position information and the signal received power of the corrected downlink reference signal is established.

应当理解的是,在一些应用场景中,第一信号也可为上行参考信号(当然,应当理解的是,除了上行参考信号外,也可以是其他任意能进行信号特征采集用于建立指纹库的上行信号),并且信号接收特征仍可包括信号接收功率,信号发送特征仍可对应地包括信号发送功率,且发送上行参考信号的设备的发送功率基本相同。It should be understood that in some application scenarios, the first signal may also be an uplink reference signal (of course, it should be understood that, in addition to the uplink reference signal, any other signal feature collection can be used to establish a fingerprint database Uplink signal), and the signal reception characteristic may still include the signal reception power, and the signal transmission characteristic may still include the signal transmission power correspondingly, and the transmission power of the device that transmits the uplink reference signal is substantially the same.

应当理解的是,本实施例中的上述修正过程是根据具体应用场景而可选的一个过程。例如,在一种示例中,在执行上述修正过程之前,还可先采集第一小区和第二小区中发送上述第一信号的信号发送特征,并判断二者的差值是否达到预设的一个阈值,如果是,才进入后续的修正步骤;否则,可不进入后续的修正过程。例如,在一种应 用场景中,当第一小区和第二小区发送上述第一信号的信号发送功率相同或基本相同,则可不进入上述修正步骤,当二者的发送功率差值大于设定阈值时,则需要进入上述修正步骤修正之后,再生成定位指纹库。当然,在一些示例中,可不做上述判断直接进入修正步骤,以适应各种应用场景。It should be understood that the above correction process in this embodiment is a process that can be selected according to specific application scenarios. For example, in one example, before performing the above correction process, the signal transmission characteristics of the first cell and the first cell in the first cell and the second cell may also be collected, and whether the difference between the two reaches the preset one Threshold, if it is, then enter the subsequent correction step; otherwise, you can not enter the subsequent correction process. For example, in an application scenario, when the signal transmission power of the first cell and the second cell transmitting the first signal is the same or substantially the same, the above correction step may not be entered, when the difference between the transmission power of the two is greater than the set threshold At this time, you need to enter the above correction steps to correct, and then generate a positioning fingerprint library. Of course, in some examples, the correction step may be directly entered without making the above determination to adapt to various application scenarios.

应当理解的是,本实施例中除了可以通过利用第一信号的信号接收特征建立与位置信息的关联关系以生成定位指纹库外,也可利用第一信号的信号发送特征建立与位置信息的关联关系以生成定位指纹库,或者同时利用第一信号的信号发送特征和信号接收特征与位置信息的关联管理以生成定位指纹库,生成定位指纹库的方式都可采用上述图1所示的方式。It should be understood that in this embodiment, in addition to using the signal receiving feature of the first signal to establish an association relationship with the location information to generate a positioning fingerprint database, the signal sending feature of the first signal may also be used to establish an association with the location information The relationship is used to generate a positioning fingerprint database, or the association management of the signal transmission characteristics and signal receiving characteristics of the first signal and the location information is used to generate a positioning fingerprint database at the same time.

为了使构建的第二网络制式的定位指纹库中的信息更为全面,以便于后续可以从多个不同的角度对第二网络制式下的待定位终端进行定位,在本实施例中还可利用第二网络制式的第二信号建立定位指纹库,此时步骤S103可包括:获取第二小区中的第二信号和第一信号的映射关系;以及根据第二小区中第二信号和第一信号的映射关系、第二小区中的第一信号和第一小区中的对应的所述第一信号,以及第一小区中第一信号对应的位置信息,建立第二小区中的第二信号和对应的位置信息的关联关系,生成第二网络制式的定位指纹库。In order to make the information in the positioning fingerprint library of the second network standard constructed more comprehensive, so that the terminal to be positioned under the second network standard can be positioned from multiple different angles in the following, it can also be used in this embodiment The second signal of the second network standard establishes a positioning fingerprint database. In this case, step S103 may include: acquiring a mapping relationship between the second signal and the first signal in the second cell; and according to the second signal and the first signal in the second cell Mapping relationship between the first signal in the second cell and the corresponding first signal in the first cell, and the location information corresponding to the first signal in the first cell, to establish the second signal and correspondence in the second cell The association relationship of the location information to generate a positioning fingerprint database of the second network standard.

例如,一种示例中,第二信号可为上行参考信号,第一信号可为下行参考信号(当然第二信号也可为下行参考信号,第一信号也可为上行参考信号),此时,获取第二小区中的第二信号和第一信号的映射关系包括:在第二小区中,在某一第二信号的信号特征的最高概率的取值,与某一第一信号的信号特征的取值匹配时,确定该第二信号和第一信号对应;或者,在第二小区中,在某一第一信号的信号特征的最高概率的取值,与某一第二信号的信号特征的取值匹配时,确定该第二信号和第一信号对应。For example, in an example, the second signal may be an uplink reference signal, and the first signal may be a downlink reference signal (of course, the second signal may also be a downlink reference signal, and the first signal may also be an uplink reference signal). Obtaining the mapping relationship between the second signal and the first signal in the second cell includes: in the second cell, the value of the highest probability of the signal characteristic of a certain second signal, and the value of the signal characteristic of a certain first signal When the values match, it is determined that the second signal corresponds to the first signal; or, in the second cell, the value of the highest probability of the signal characteristics of a certain first signal, and the value of the signal characteristics of a certain second signal When the values match, it is determined that the second signal corresponds to the first signal.

例如,一种示例包括如下步骤S31至S32。For example, one example includes the following steps S31 to S32.

在步骤S31,统计第二小区下的各终端在不同位置上所传输的上行参考信号的信号特征和各终端在各相应的位置上所传输的下行参 考信号的信号特征。In step S31, the signal characteristics of the uplink reference signals transmitted by the terminals in the second cell at different positions and the signal characteristics of the downlink reference signals transmitted by the terminals at the corresponding positions are counted.

具体的来说,对于第二网络制式下各第二小区中的每一终端,当该终端在某一位置上时,应当统计该终端在该位置上与某一基站之间所传输的上行参考信号的信号特征,以及该终端在该位置上与该基站之间所传输的下行参考信号的信号特征。如此,在步骤S31中就可以得到多个上行参考信号的信号特征与下行参考信号的信号特征的对应关系。Specifically, for each terminal in each second cell under the second network standard, when the terminal is at a certain location, the uplink reference transmitted between the terminal and a certain base station at that location should be counted The signal characteristics of the signal and the signal characteristics of the downlink reference signal transmitted between the terminal and the base station at the location. In this way, in step S31, the correspondence between the signal characteristics of multiple uplink reference signals and the signal characteristics of downlink reference signals can be obtained.

在步骤S32,根据统计结果建立第二小区中的上行参考信号的信号特征与下行参考信号的信号特征的映射关系。In step S32, a mapping relationship between the signal characteristics of the uplink reference signal and the signal characteristics of the downlink reference signal in the second cell is established according to the statistical results.

在步骤S32中,需要对步骤S31中得到的多个上行参考信号的信号特征与下行参考信号的信号特征的对应关系进行分析,得到上行参考信号的信号特征与下行参考信号的信号特征的映射关系。In step S32, it is necessary to analyze the correspondence relationship between the signal characteristics of the multiple uplink reference signals obtained in step S31 and the signal characteristics of the downlink reference signal to obtain the mapping relationship between the signal characteristics of the uplink reference signal and the signal characteristics of the downlink reference signal .

在一些实施例中,可以基于概率分布来建立上行参考信号的信号特征和下行参考信号的信号特征的映射关系。具体的,可以针对第二网络制式下的各第二小区的上行参考信号的每一信号特征的取值,确定出与其对应的出现概率最高的下行参考信号的信号特征的取值;或者,针对第二网络制式下的各第二小区的下行参考信号的每一信号特征的取值,确定出与其对应的出现概率最高的上行参考信号的信号特征的取值。In some embodiments, the mapping relationship between the signal characteristics of the uplink reference signal and the signal characteristics of the downlink reference signal may be established based on the probability distribution. Specifically, the value of the signal characteristic of the downlink reference signal with the highest occurrence probability may be determined for the value of each signal characteristic of the uplink reference signal of each second cell under the second network standard; or, for The value of each signal characteristic of the downlink reference signal of each second cell under the second network standard determines the value of the signal characteristic of the uplink reference signal corresponding to the highest occurrence probability.

如此得到的第二网络制式的定位指纹库中就包括上行参考信号的信号特征、下行参考信号的信号特征与位置信息之间的映射关系,从而在定位阶段,就可以根据待定位终端的上行参考信号的信号特征和/或下行参考信号的信号特征在定位指纹库中进行匹配,以确定待定位终端的位置。当然,应当理解的是,在指纹库中也可灵活的设置仅保存上行参考信号的信号特征与位置信息之间的关联关系,或仅保存下行参考信号的信号特征与位置信息之间的关联关系。The positioning fingerprint database of the second network standard thus obtained includes the mapping relationship between the signal characteristics of the uplink reference signal, the signal characteristics of the downlink reference signal and the position information, so that in the positioning stage, the uplink reference of the terminal to be positioned can be based on The signal characteristics of the signal and/or the signal characteristics of the downlink reference signal are matched in the positioning fingerprint database to determine the location of the terminal to be positioned. Of course, it should be understood that the fingerprint database can also be flexibly set to store only the correlation between the signal characteristics of the uplink reference signal and the location information, or only the correlation between the signal characteristics of the downlink reference signal and the location information .

本公开实施例还提供一种基于上述指纹库建立方法的定位方法,请参见图4所示,根据本公开实施例的定位方法包括如下步骤S401至S402。An embodiment of the present disclosure also provides a positioning method based on the above fingerprint library establishment method. Referring to FIG. 4, the positioning method according to the embodiment of the present disclosure includes the following steps S401 to S402.

在步骤S401,获取处于第二网络制式下的待定位终端所处位置 对应的第二小区中所传输的信号的信号特征。In step S401, the signal characteristics of the signal transmitted in the second cell corresponding to the location of the terminal to be located under the second network standard are obtained.

本实施例中的信号也可以包括上行参考信号和下行参考信号中的至少一种,例如,在第一种示例中,上述第一信号为下行参考信号,此处的信号为上行参考信号;在第二种示例中,上述第一信号为下行参考信号,此处的信号为下行参考信号;在第三种示例中,上述第一信号为上行参考信号,此处的信号为下行参考信号;在第四种示例中,上述第一信号为上行参考信号,此处的信号为上行参考信号。The signal in this embodiment may also include at least one of an uplink reference signal and a downlink reference signal. For example, in the first example, the above-mentioned first signal is a downlink reference signal, and the signal here is an uplink reference signal; In the second example, the above-mentioned first signal is a downlink reference signal, and the signal here is a downlink reference signal; in the third example, the above-mentioned first signal is an uplink reference signal, and the signal here is a downlink reference signal; In a fourth example, the above-mentioned first signal is an uplink reference signal, and the signal here is an uplink reference signal.

需要说明的是,步骤S401中的第二小区可以是第二网络制式下为该待定位终端服务的服务小区或为该待定位终端服务的服务小区的邻区。It should be noted that the second cell in step S401 may be a serving cell serving the terminal to be located or a neighboring cell of the serving cell serving the terminal to be located under the second network standard.

在步骤S402,根据第二小区中所传输的信号的信号特征与第二网络制式的定位指纹库确定出对应的位置信息作为该待定位终端的定位结果。In step S402, the corresponding location information is determined as the location result of the terminal to be located according to the signal characteristics of the signal transmitted in the second cell and the location fingerprint database of the second network standard.

根据本公开实施例提供的指纹库建立方法、定位方法,获取第一网络制式下的终端所处位置的位置信息,以及与该位置信息对应的第一网络制式下的第一小区所传输的第一信号的信号特征;确定第二网络制式中与第一小区具有相同通信资源的第二小区,其中,通信资源包括天线资源;以及根据第二小区和第一小区的对应关系以及终端的位置信息与第一小区所传输的第一信号的信号特征的对应关系建立第二网络制式的定位指纹库。在某些实施过程中,可以通过第一网络制式下第一小区中所传输的第一信号的信号特征和对应的位置信息来构建第二网络制式的定位指纹库,从而便可实现对第二网络制式下的待定位终端的定位。这种跨网络指纹库建立方法解决了这样的问题,即,当无法直接采集第二网络制式下的信号特征时就无法建立第二网络制式对应的定位指纹库,更无法对第二网络制式中的终端进行定位,特别的,通过直接采集的第一网络制式下的信号特征和位置信息便可建立第一网络制式对应的定位指纹库和第二网络制式对应的定位指纹库,无需针对两种网络制式分别进行信息采集,提升了建立定位指纹库的效率。According to the fingerprint library establishment method and the positioning method provided in the embodiments of the present disclosure, the location information of the location of the terminal under the first network standard and the first cell under the first network standard corresponding to the location information transmitted by the first cell corresponding to the location information are acquired. Signal characteristics of a signal; determining a second cell with the same communication resources as the first cell in the second network standard, wherein the communication resources include antenna resources; and according to the correspondence between the second cell and the first cell and the location information of the terminal The corresponding relationship with the signal characteristics of the first signal transmitted by the first cell establishes a positioning fingerprint library of the second network standard. In some implementation processes, the positioning fingerprint library of the second network standard can be constructed through the signal characteristics and corresponding location information of the first signal transmitted in the first cell under the first network standard, so that the second The positioning of the terminal to be located under the network standard. This method of establishing a cross-network fingerprint library solves the problem that when the signal characteristics under the second network standard cannot be directly collected, the positioning fingerprint library corresponding to the second network standard cannot be established, and even the second network standard cannot be established. Positioning of the terminal, in particular, the positioning fingerprint database corresponding to the first network standard and the positioning fingerprint database corresponding to the second network standard can be established by directly collecting the signal characteristics and position information under the first network standard, without needing to target two The network format separately collects information, which improves the efficiency of establishing a positioning fingerprint database.

为了更好的进行理解,以第一网络制式为LTE(Long Term  Evolution,长期演进)网络,第二网络制式为NB-IoT(Narrow Band Internet of Things,窄带物联)网络为例进行具体说明。应当理解的是,本示例仅是以LTE网络和NB-IoT网络进行示例,并不是对本方案的限定,在其他的实施方式中,第一网络制式和第二网络制式还可以是GSM(Global System for Mobile Communication,全球移动通信系统)网络、CDMA(Code Division Multiple Access,码分多址)网络等等,只要满足第一网络制式和第二网络制式不同即可。For a better understanding, the first network standard is an LTE (Long Term Evolution) network and the second network standard is an NB-IoT (Narrow Band Internet of Things) network as an example for specific description. It should be understood that this example is only an example of an LTE network and an NB-IoT network, and is not a limitation of the solution. In other embodiments, the first network standard and the second network standard may also be GSM (Global System For Mobile Communication (Global System for Mobile Communications) networks, CDMA (Code Division Multiple Access, Code Division Multiple Access) networks, etc., as long as the first network standard and the second network standard are different.

假设本示例中的第一信号为下行参考信号,在定位时采用的信号(本示例称之为第二信号)为上行参考信号,本示例中假设下行参考信号的信号接收功率为下行导频RSRP的接收功率。It is assumed that the first signal in this example is a downlink reference signal, and the signal used in positioning (referred to as the second signal in this example) is an uplink reference signal. In this example, it is assumed that the received signal power of the downlink reference signal is the downlink pilot RSRP Received power.

基于上述假设条件,下面对本示例所提供的指纹库建立方法进行介绍。请参见图5所示,本示例所提供的指纹库建立方法包括步骤S501至S%04。Based on the above assumptions, the fingerprint library establishment method provided in this example is introduced below. Please refer to FIG. 5, the fingerprint library establishment method provided in this example includes steps S501 to S%04.

在步骤S501,位于LTE网络下的终端A将自身测量的LTE网络中相应小区的下行参考信号的信号接收功率、相应小区的标识信息、以及自身的位置信息通过测量报告发送给相应的基站。In step S501, the terminal A located under the LTE network transmits the signal received power of the downlink reference signal of the corresponding cell in the LTE network measured by itself, the identification information of the corresponding cell, and its own location information to the corresponding base station through the measurement report.

步骤S501中的相应小区中包括为终端A服务的小区,以及该小区的邻区。The corresponding cell in step S501 includes the cell serving terminal A and the neighboring cell of the cell.

假设终端A测量的是LTE网络中编号为A1至A5的小区的RSRP,其中,终端A以小区A1为服务小区,A2至A5为A1的邻区,本示例中的小区的标识信息为小区ID,A1至A5的小区ID分别为638020051、638020050、638020049、638020048、638020047。步骤S501中的测量报告中包含的信息可以参见如下表一所示:Assume that terminal A measures RSRP of cells numbered A1 to A5 in the LTE network, where terminal A uses cell A1 as the serving cell and A2 to A5 are the neighboring cells of A1. The identification information of the cell in this example is the cell ID The cell IDs of A1 to A5 are 638020051, 638020050, 638020049, 638020048, and 638020047, respectively. The information contained in the measurement report in step S501 can be referred to as shown in Table 1 below:

表一Table I

Figure PCTCN2019124764-appb-000001
Figure PCTCN2019124764-appb-000001

在步骤S502,基站接收到终端上报的测量报告后,将其发送给服务器。In step S502, after receiving the measurement report reported by the terminal, the base station sends it to the server.

步骤S502中的服务器可以是MEC(Mobi le Edge Computing,移动边缘计算)。The server in step S502 may be MEC (Mobi Edge Computing, mobile edge computing).

该服务器上记录了LTE网络中小区A1至A5的工作频段,小区天线ID和下行发射功率。同时还记录了NB-IoT网络中小区B1至B5的工作频段,小区天线ID和下行发射功率。其中B1至B5小区的小区ID分别为638020091、638020090、638020089、638020088、638020087,小区A1和A5和小区B1至B5使用的频段信息以及小区天线ID如下表二所示:The server records the working frequency bands of the cells A1 to A5 in the LTE network, the cell antenna ID and the downlink transmit power. At the same time, the working frequency bands of cells B1 to B5 in the NB-IoT network, the cell antenna ID and the downlink transmit power are also recorded. The cell IDs of cells B1 to B5 are 638020091, 638020090, 638020089, 638020088, and 638020087. The frequency band information and cell antenna IDs used by cells A1 and A5 and cells B1 to B5 are shown in Table 2 below:

表二Table II

Figure PCTCN2019124764-appb-000002
Figure PCTCN2019124764-appb-000002

在步骤S503,服务器对测量报告中的数据进行筛选。In step S503, the server filters the data in the measurement report.

服务器对比LTE终端A上报的测量报告中的LTE网络中的小区的频段信息和天线ID与NB-IoT网络中的小区是否一致。通过对比上表中小区A1至A5与B1至B5小区的信息可以确定:LTE网络中的小区A4所使用的天线ID与NB-IoT网络中B1至B5小区使用的天线ID 均不同,LTE小区A5使用的频段与NB-IoT小区B1至B5使用的频段均不同。因此A4和A5小区对应的下行参考信号的信号接收功率不能用于生成NB-IoT网络的定位指纹库。经筛选后的测量报告中的信息为表三:The server compares whether the frequency band information and antenna ID of the cell in the LTE network in the measurement report reported by LTE terminal A are consistent with the cell in the NB-IoT network. By comparing the information of the cells A1 to A5 and B1 to B5 in the above table, it can be determined that the antenna ID used by cell A4 in the LTE network is different from the antenna ID used by cells B1 to B5 in the NB-IoT network. LTE cell A5 The frequency band used is different from the frequency bands used by NB-IoT cells B1 to B5. Therefore, the received signal power of the downlink reference signals corresponding to the A4 and A5 cells cannot be used to generate the location fingerprint database of the NB-IoT network. The information in the screened measurement report is shown in Table 3:

表三Table 3

Figure PCTCN2019124764-appb-000003
Figure PCTCN2019124764-appb-000003

经过上述筛选便可得到与终端A所处位置对应的LTE网络中的第一小区为小区A1至A3。After the above screening, the first cells in the LTE network corresponding to the location of terminal A are cells A1 to A3.

在步骤S504,对筛选后的测量报告中的信息进行更新,生成NB-IoT网络的定位指纹库。In step S504, the information in the filtered measurement report is updated to generate a location fingerprint database of the NB-IoT network.

这里的更新是基于LTE网络下各基站与NB-IoT网络下相应基站之间的差异进行更新,所谓的差异包括但不限于基站间对应小区的信号发射功率(下行发射功率)的差异,对应的小区的标识信息的差异。服务器对比LTE网络小区和NB-IoT网络小区的下行发射功率,调整LTE网络小区下行参考信号的信号接收功率的取值。从表二中可以确定,小区A2与小区B2使用相同的频段和天线,但是小区B2的下行发射功率低于小区A2的下行发射功率,且两者之差为3dB。因此,将测量报告中A2小区对应的RSRP值降低3dB。更新后的测量报告中的信息如表四所示:The update here is based on the difference between each base station under the LTE network and the corresponding base station under the NB-IoT network. The so-called difference includes but is not limited to the difference in the signal transmission power (downlink transmission power) of the corresponding cell between the base stations. Differences in cell identification information. The server compares the downlink transmission power of the LTE network cell and the NB-IoT network cell, and adjusts the value of the signal reception power of the downlink reference signal of the LTE network cell. It can be determined from Table 2 that cell A2 and cell B2 use the same frequency band and antenna, but the downlink transmit power of cell B2 is lower than that of cell A2, and the difference between the two is 3 dB. Therefore, the RSRP value corresponding to the A2 cell in the measurement report is reduced by 3 dB. The information in the updated measurement report is shown in Table 4:

表四Table 4

Figure PCTCN2019124764-appb-000004
Figure PCTCN2019124764-appb-000004

该测量报告中A1至A3小区的RSRP值记录在终端所处的位置处,由于LTE网络小区A1,A2和A3分别与NB-IoT网络小区B1,B2,B3的工作频段和天线完全一致,所以网络小区B1、B2、B3是与上述第一小区对应的NB-IoT网络中的第二小区,所以可以将LTE网络中对应的小区ID替换为NB-IoT网络中对应的小区ID,也即是将A1、A2 和A3分别替换为B1、B2和B3,以便在从NB-IoT网络中接收到NB-IoT网络中待定位终端的信号特征时提高计算的效率,如此得到的NB-IoT网络的定位指纹库的部分可以参见下表五所示:In this measurement report, the RSRP values of cells A1 to A3 are recorded at the location of the terminal. Since the LTE network cells A1, A2, and A3 are completely consistent with the NB-IoT network cells B1, B2, and B3, the operating frequency band and antenna are completely the same. The network cells B1, B2, and B3 are the second cells in the NB-IoT network corresponding to the first cell, so the corresponding cell ID in the LTE network can be replaced with the corresponding cell ID in the NB-IoT network, that is, Replace A1, A2, and A3 with B1, B2, and B3, respectively, to improve the efficiency of the calculation when receiving the signal characteristics of the terminal to be located in the NB-IoT network from the NB-IoT network. For the location of the fingerprint database, please refer to Table 5 below:

表五Table 5

Figure PCTCN2019124764-appb-000005
Figure PCTCN2019124764-appb-000005

应当说明的是,上述对根据LTE网络中终端A上报的测量报告生成NB-IoT网络的定位指纹库的部分内容的过程进行了介绍,在实际应用中,为了缩短定位指纹库建立的时间,提升效率,应当同时在LTE网络的各个位置下部署相应的终端,执行与上述类似的过程,从而形成NB-IoT网络的定位指纹库。It should be noted that the above describes the process of generating part of the content of the location fingerprint database of the NB-IoT network based on the measurement report reported by terminal A in the LTE network. In practical applications, in order to shorten the establishment time of the location fingerprint database and improve For efficiency, corresponding terminals should be deployed at various locations on the LTE network at the same time, and a process similar to the above should be performed to form a location fingerprint database of the NB-IoT network.

上述步骤S501至步骤S504是建立NB-IoT网络的定位指纹库的过程,应当理解的是,当NB-IoT网络的定位指纹库建立完成之后,可以对NB-IoT网络下中的终端进行定位。假设本示例中基于上行参考信号的信号接收功率进行定位,并假设上行参考信号的信号接收功率为上行随机接入前导信号NPRACH的接收功率,具体的请参见图6所示,本示例所提供的定位方法包括步骤S601至S603。The above steps S501 to S504 are the process of establishing the location fingerprint database of the NB-IoT network. It should be understood that, after the location fingerprint database of the NB-IoT network is established, the terminals in the NB-IoT network can be located. It is assumed in this example that the positioning is based on the received signal power of the uplink reference signal, and it is assumed that the received signal power of the uplink reference signal is the received power of the uplink random access preamble signal NPRACH. For details, please refer to FIG. 6, which is provided in this example. The positioning method includes steps S601 to S603.

在步骤S601,服务器接收NB-IoT网络下的待定位终端B发送的定位请求。In step S601, the server receives a positioning request sent by terminal B to be positioned under the NB-IoT network.

服务器在接收到定位请求后,可以通知基站对待定位终端发送的上行随机接入前导信号进行测量。本示例中通信系统的示意图如图7所示。图7中的LTE网络下包含终端A与小区A,以及其他未示出的终端和小区,NB-IoT网络包含终端B和小区B,服务器70可以与NB-IoT网络下的小区B对应的基站或者终端B进行通信,服务器70可以与LTE网络下的小区A对应的基站或者终端A进行通信。After receiving the positioning request, the server may notify the base station to measure the uplink random access preamble signal sent by the terminal to be positioned. The schematic diagram of the communication system in this example is shown in FIG. 7. The LTE network in FIG. 7 includes terminal A and cell A, and other terminals and cells not shown. The NB-IoT network includes terminal B and cell B. The server 70 may correspond to a base station corresponding to cell B under the NB-IoT network. Or terminal B communicates, and server 70 may communicate with the base station or terminal A corresponding to cell A under the LTE network.

应当说明的是,终端B可以通过基站将定位请求发送给服务器,基站就可以获得当前为该终端B服务的服务小区的标识信息,并将该信息发送给服务器,以便于服务器后续以服务小区的标识信息为基准对待定位终端B进行定位。It should be noted that terminal B can send a positioning request to the server through the base station, and the base station can obtain the identification information of the serving cell currently serving the terminal B and send the information to the server, so that the server can subsequently use the serving cell The identification information is used as a reference to locate the terminal B to be located.

在步骤S602,NB-IoT网络中的基站对终端B发送的上行随机接 入前导信号进行测量并发送给服务器。In step S602, the base station in the NB-IoT network measures the uplink random access preamble signal sent by terminal B and sends it to the server.

应当说明的是,接收到该上行随机接入前导信号的基站应当针对该基站的为该终端B服务的服务小区上的上行随机接入前导信号进行测量,并通知与该服务小区相邻的小区对应的基站针对该相应相邻小区上的上行随机接入前导信号进行测量,如此便可测得如下表六的数据:It should be noted that the base station that received the uplink random access preamble signal should measure the uplink random access preamble signal on the serving cell serving the terminal B of the base station, and notify the cell adjacent to the serving cell The corresponding base station measures the uplink random access preamble signal on the corresponding neighboring cell, so that the data in the following Table 6 can be measured:

表六Table 6

Figure PCTCN2019124764-appb-000006
Figure PCTCN2019124764-appb-000006

在步骤S603,服务器根据接收到的待定位终端B的上行随机接入前导信号的接收功率与NB-IoT网络的定位指纹库进行匹配,计算出待定位终端B的位置。In step S603, the server matches the received power of the uplink random access preamble signal of the terminal B to be located with the location fingerprint database of the NB-IoT network, and calculates the location of the terminal B to be located.

本示例中利用上行信号进行位置的匹配,可以同时测量一组小区的上行信号特征,也即可以同时测量一组小区的上行随机接入前导信号的接收功率,同步测量保证了定位的准确性,减少了终端侧的耗电量和成本投入。In this example, the uplink signal is used for position matching, and the uplink signal characteristics of a group of cells can be measured simultaneously, that is, the received power of the uplink random access preamble signal of a group of cells can be measured simultaneously, and synchronous measurement ensures the accuracy of positioning. Reduced power consumption and cost input on the terminal side.

可以理解的是,在一些实施例中,可以直接将待定位终端的上行信号特征代入定位指纹库中进行匹配,无需将待定位终端的上行信号特征转换成下行信号特征,但是在其他的一些实施例中,还可以进行此转换过程,此时则需要预先在定位指纹库中建立上行信号特征和下行信号特征的映射关系,这样可以使得定位指纹库所依赖的测量对象更加丰富,在定位阶段也可以从多个不同的角度进行定位。It can be understood that, in some embodiments, the uplink signal features of the terminal to be located can be directly substituted into the positioning fingerprint database for matching, without converting the uplink signal features of the terminal to be located into downlink signal features, but in other implementations For example, this conversion process can also be performed. In this case, the mapping relationship between the upstream signal feature and the downstream signal feature needs to be established in the positioning fingerprint library in advance, which can make the measurement objects that the positioning fingerprint library depends on more abundant. Can be positioned from many different angles.

下面对建立NB-IoT网络上行信号特征与下行信号特征映射关系的过程进行介绍,应当说明的是,此过程可以发生在建立NB-IoT网络的定位指纹库的阶段,本示例以上行信号特征为上行参考信号的接收功率,下行信号特征为下行参考信号的接收功率为例进行示例说明,具体的请参见图8所示,本示例所提供的建立上行信号特征与下行信号特征映射关系的过程包括步骤S801至S803。The following describes the process of establishing the mapping relationship between the uplink signal characteristics and the downlink signal characteristics of the NB-IoT network. It should be noted that this process can occur at the stage of establishing the location fingerprint library of the NB-IoT network. In this example, the upstream signal characteristics It is the received power of the uplink reference signal, and the downlink signal characteristic is the received power of the downlink reference signal as an example. For details, please refer to FIG. 8. The process of establishing the mapping relationship between the uplink signal characteristic and the downlink signal characteristic provided by this example Steps S801 to S803 are included.

在步骤S801,针对NB-IoT网络下的各小区统计上行参考信号的 接收功率和下行参考信号的接收功率。In step S801, the received power of the uplink reference signal and the received power of the downlink reference signal are counted for each cell under the NB-IoT network.

应当说明的是,本示例中可以针对各小区长时间统计大量终端的上行参考信号的接收功率,得到各小区覆盖范围内的上行参考信号的接收功率的取值空间,并针对各小区长时间统计大量终端的下行参考信号的接收功率,得到各小区覆盖范围内的下行参考信号的接收功率的取值空间。比如,基站可以周期性的对NB-IoT网络下终端的上行随机接入前导信号的接收功率进行测量,并上报给服务器,NB-IoT网络下终端可以周期性的对下行参考信号的接收功率进行测量。It should be noted that, in this example, the reception power of the uplink reference signal of a large number of terminals can be counted for each cell for a long time to obtain the value space of the reception power of the uplink reference signal within the coverage of each cell, and the long-term statistics for each cell The received power of the downlink reference signal of a large number of terminals can obtain the value space of the received power of the downlink reference signal within the coverage of each cell. For example, the base station can periodically measure the received power of the uplink random access preamble signal of the terminal under the NB-IoT network and report it to the server, and the terminal under the NB-IoT network can periodically measure the received power of the downlink reference signal measuring.

可以理解的是,步骤S801中,服务器可以主动在终端或者基站中查询相关的下行参考信号的接收功率和上行参考信号的接收功率,也可以接收由终端或者基站分别发送的下行参考信号的接收功率和上行参考信号的接收功率。It can be understood that, in step S801, the server may actively query the received power of the downlink reference signal and the received power of the uplink reference signal in the terminal or the base station, and may also receive the received power of the downlink reference signal sent by the terminal or the base station respectively And the received power of the upstream reference signal.

在其他的一些实施方式中可以针对NB-IoT网络进行统计,也即不区分其对应的小区。In some other embodiments, statistics can be made for the NB-IoT network, that is, the corresponding cells are not distinguished.

在步骤S802,确定各小区的上行参考信号的接收功率和下行参考信号的接收功率的样本数量分别都大于预设数量阈值。In step S802, it is determined that the number of samples of the received power of the uplink reference signal and the received power of the downlink reference signal of each cell is greater than a preset number threshold.

本示例中的预设数量阈值可以任意设置,比如可以设置为10000,如此可以保证上行参考信号的接收功率和下行参考信号的接收功率之间映射关系的准确性。The preset number threshold in this example can be set arbitrarily, for example, it can be set to 10000, so as to ensure the accuracy of the mapping relationship between the received power of the uplink reference signal and the received power of the downlink reference signal.

在步骤S803,针对各小区的上行参考信号的每一接收功率的取值,确定出与其对应的出现概率最高的下行参考信号的接收功率的取值。In step S803, for each value of the received power of the uplink reference signal of each cell, the value of the received power of the downlink reference signal corresponding to the highest occurrence probability is determined.

本步骤中,需要针对各小区统计上行参考信号在其接收功率取值区间中出现某值时,对应的下行参考信号的接收功率取值的概率分布函数,该概率分布函数表示了相应小区覆盖范围内的上行参考信号的接收功率与下行参考信号的接收功率的映射关系。可以选择出现概率最高的下行参考信号的接收功率,如此便可得到NB-IoT网络的各小区的上行参考信号的接收功率和下行参考信号的接收功率的映射关系,在定位阶段中,接收到待定位终端的上行参考信号的接收功率后,可以根据该映射关系确定出对应的下行参考信号的接收功率,在 确定出与该下行参考信号的接收功率对应的位置。In this step, the probability distribution function of the received power value of the corresponding downlink reference signal needs to be counted for each cell when a certain value appears in the received power value interval of the uplink reference signal. The probability distribution function represents the coverage area of the corresponding cell The mapping relationship between the received power of the uplink reference signal and the received power of the downlink reference signal in. The received power of the downlink reference signal with the highest probability of occurrence can be selected, so that the mapping relationship between the received power of the uplink reference signal and the received power of the downlink reference signal in each cell of the NB-IoT network can be obtained. After the received power of the uplink reference signal of the bit terminal, the received power of the corresponding downlink reference signal can be determined according to the mapping relationship, and the position corresponding to the received power of the downlink reference signal can be determined.

根据本公开实施例,提供一种指纹库建立装置,请参见图9所示,根据本公开实施例的指纹库建立装置包括第一获取模块901、确定模块902和构建模块903。第一获取模块901用于获取第一网络制式下的终端所处位置的位置信息,以及与该位置信息对应的第一网络制式下的第一小区所传输的第一信号的信号特征。确定模块902用于确定第二网络制式中与第一小区具有相同通信资源的第二小区。构建模块903根据所述第一信号的信号特征,以及所述第一信号的信号特征对应的位置信息,生成所述第二网络制式的定位指纹库。According to an embodiment of the present disclosure, an apparatus for establishing a fingerprint database is provided. Referring to FIG. 9, the apparatus for establishing a fingerprint database according to an embodiment of the present disclosure includes a first obtaining module 901, a determining module 902, and a building module 903. The first obtaining module 901 is used to obtain the location information of the location of the terminal under the first network standard and the signal characteristics of the first signal transmitted by the first cell under the first network standard corresponding to the location information. The determining module 902 is used to determine a second cell with the same communication resources as the first cell in the second network standard. The construction module 903 generates the positioning fingerprint library of the second network standard according to the signal characteristics of the first signal and the location information corresponding to the signal characteristics of the first signal.

应当说明的是,在一些实施例中,指纹库建立装置还可以包括筛选模块,用于在第一获取模块获取第一网络制式下的终端所处位置的位置信息,以及与该位置信息对应的第一网络制式下的第一小区所传输的第一信号的信号特征之前,从与终端所处的位置对应的第一网络制式下的小区中筛选出与第二网络制式中的小区具有相同通信资源的第一小区。本实施例中的通信资源包括天线资源和频段资源。It should be noted that, in some embodiments, the fingerprint library building device may further include a screening module for acquiring the location information of the location of the terminal under the first network standard in the first acquisition module, and the location information corresponding to the location information Before the signal characteristics of the first signal transmitted by the first cell under the first network standard, the cell under the first network standard corresponding to the location of the terminal is selected to have the same communication with the cell under the second network standard The first cell of the resource. The communication resources in this embodiment include antenna resources and frequency band resources.

本实施例中所提及的与相应位置信息对应的第一网络制式下的第一小区可以包括:终端在相应的位置上传输第一信号时,为该终端服务的服务小区或为该终端服务的服务小区的邻区。The first cell under the first network standard corresponding to the corresponding location information mentioned in this embodiment may include: when the terminal transmits the first signal at the corresponding location, a serving cell serving the terminal or serving the terminal The neighboring cell of the serving cell.

需要说明的是,本实施例中的第一信号包括上行参考信号(当然,应当理解的是,除了下行参考信号外,也可以是其他任意能进行信号特征采集用于建立指纹库的下行信号)和/或下行参考信号(当然,应当理解的是,除了上行参考信号外,也可以是其他任意能进行信号特征采集用于建立指纹库的上行信号)。本实施例中信号特征可以是任意的可以表明终端与相应基站之间进行信号传输时的路损的数据,包括但不限于是信号接收功率和/或信号时延,另外应当说明的是,本实施例提供的指纹库建立装置可以应用于服务器上。It should be noted that the first signal in this embodiment includes an uplink reference signal (of course, it should be understood that, in addition to the downlink reference signal, it can be any other downlink signal that can perform signal feature collection to establish a fingerprint database) And/or downlink reference signal (of course, it should be understood that, in addition to the uplink reference signal, any other uplink signal that can be used for signal feature collection to establish a fingerprint database). The signal characteristics in this embodiment may be any data that can indicate the path loss during signal transmission between the terminal and the corresponding base station, including but not limited to the signal received power and/or signal delay. In addition, it should be noted that The fingerprint library creation device provided in the embodiment can be applied to a server.

本实施例中的服务器上可以预先存储第一网络制式下的各基站所对应的各小区的通信资源以及第二网络制式下的各基站所对应的各小区的通信资源,根据这些信息,便可确定出与第二网络制式下与第一小区具有相同通信资源的第二小区。The server in this embodiment may pre-store the communication resources of each cell corresponding to each base station under the first network system and the communication resources of each cell corresponding to each base station under the second network system. Based on the information, A second cell having the same communication resources as the first cell under the second network standard is determined.

当第一信号包括下行参考信号时,可以由第一网络制式下的终端直接测量第一网络制式下的第一小区所传输的下行参考信号的信号特征。本实施例中,第一获取模块901可以直接接收由终端测量并发送的位置信息和下行参考信号的信号特征,也可以接收由相应的基站发送的位置信息和下行参考信号的信号特征。此时,终端应当将检测到的位置信息和下行参考信号的信号特征发送给相应的基站。对于此种示例,服务器可以将第一网络制式中的与第二网络制式下的小区具有相同的通信资源的小区的信息发送给各终端,直接对各终端进行提示,这样,第一网络制式下的终端就可以不测量与第二网络制式下的小区不具有相同通信资源的小区所传输的下行参考信号的信号特征,这样,服务器就可以直接接收到需要的位置信息和对应的第一小区所传输的第一信号的信号特征,无需进行信息的筛选。When the first signal includes a downlink reference signal, the terminal under the first network standard may directly measure the signal characteristics of the downlink reference signal transmitted by the first cell under the first network standard. In this embodiment, the first acquisition module 901 may directly receive the position information and the signal characteristics of the downlink reference signal measured and sent by the terminal, or may receive the position information and the signal characteristics of the downlink reference signal sent by the corresponding base station. At this time, the terminal should send the detected location information and the signal characteristics of the downlink reference signal to the corresponding base station. For this example, the server may send the information of the cell in the first network mode that has the same communication resources as the cell in the second network mode to each terminal, and directly prompt each terminal. In this way, under the first network mode The terminal can not measure the signal characteristics of the downlink reference signal transmitted by the cell that does not have the same communication resources as the cell under the second network standard, so that the server can directly receive the required location information and the corresponding first cell. The signal characteristics of the transmitted first signal do not require information screening.

当第一信号包括上行参考信号时,可以由终端检测位置信息,并将该位置信息发送给相应的基站,基站测量第一小区所传输的上行参考信号的信号特征,第一获取模块901可以接收基站发送的位置信息和第一小区所传输的上行参考信号的信号特征。对于此种示例,服务器可以将第一网络制式中的与第二网络制式下的小区具有相同的通信资源的小区的信息发送给各基站,直接对各基站进行提示,这样,第一网络制式下的一些基站就可以不测量与第二网络制式下的小区不具有相同通信资源的小区所传输的上行参考信号的信号特征,这样,服务器照样可以直接接收到需要的位置信息和对应的第一小区所传输的第一信号的信号特征,无需进行信息的筛选。When the first signal includes the uplink reference signal, the terminal can detect the location information and send the location information to the corresponding base station. The base station measures the signal characteristics of the uplink reference signal transmitted by the first cell, and the first acquisition module 901 can receive The location information sent by the base station and the signal characteristics of the uplink reference signal transmitted by the first cell. For this example, the server may send the information of the cell in the first network mode that has the same communication resources as the cell in the second network mode to each base station, and directly prompt each base station. In this way, under the first network mode Some of the base stations may not measure the signal characteristics of the uplink reference signal transmitted by the cell that does not have the same communication resources as the cell under the second network standard, so that the server can still directly receive the required location information and the corresponding first cell The signal characteristics of the transmitted first signal do not require information screening.

应当说明的是,为了提升定位效率,构建模块903可以将终端的位置信息与第一小区所传输的第一信号的信号特征的对应关系中的第一小区替换成第二小区,也即是建立终端的位置信息与第二小区所传输的第一信号的信号特征的直接对应关系。It should be noted that, in order to improve the positioning efficiency, the construction module 903 may replace the first cell in the correspondence between the location information of the terminal and the signal characteristics of the first signal transmitted by the first cell with the second cell, that is, establish There is a direct correspondence between the location information of the terminal and the signal characteristics of the first signal transmitted by the second cell.

在另一示例中,为了建立更精确的定位指纹库以便于后续精准定位,构建模块903还可先以第二网络制式中对应的第一信号的信号特征为基准,对第一网络制式中第一小区对应的第一信号的信号特征进行修正处理,然后基于修正处理之后的第一信号的信号特征与位置 信息建立定位指纹库;具体修正过程参见上述各实施例所示,在此不再赘述。In another example, in order to establish a more accurate positioning fingerprint database for subsequent accurate positioning, the construction module 903 may also first use the signal characteristics of the corresponding first signal in the second network standard as a reference Perform correction processing on the signal characteristics of the first signal corresponding to a cell, and then establish a positioning fingerprint database based on the signal characteristics and position information of the first signal after the correction processing; for the specific correction process, refer to the foregoing embodiments, which will not be repeated here. .

应当理解的是,构建模块903执行的上述修正过程是根据具体应用场景而可选的一个过程。例如,在一种示例中,在执行上述修正过程之前,还可先采集第一小区和第二小区中发送上述第一信号的信号发送特征,并判断二者的差值是否达到预设的一个阈值,如果是,才进入后续的修正步骤;否则,可不进入后续的修正过程。当然,在一些示例中,构建模块903也可不做上述判断直接进入修正步骤,以适应各种应用场景。It should be understood that the above correction process performed by the building module 903 is an optional process according to specific application scenarios. For example, in one example, before performing the above correction process, the signal transmission characteristics of the first cell and the first cell in the first cell and the second cell may also be collected, and whether the difference between the two reaches the preset one Threshold, if it is, then enter the subsequent correction step; otherwise, you can not enter the subsequent correction process. Of course, in some examples, the building module 903 may directly enter the correction step without making the above determination to adapt to various application scenarios.

为了使构建的第二网络制式的定位指纹库中的信息更为全面,以便于后续可以从多个不同的角度对第二网络制式下的待定位终端进行定位,在本实施例中的第一信号为上行参考信号或下行参考信号时,构建模块903还可利用第二网络制式的第二信号建立定位指纹库,此时构建模块903可用于:获取第二小区中的第二信号和第一信号的映射关系;以及根据第二小区中第二信号和第一信号的映射关系、第二小区中的第一信号和第一小区中的对应的所述第一信号,以及第一小区中第一信号对应的位置信息,建立第二小区中的第二信号和对应的位置信息的关联关系,生成第二网络制式的定位指纹库。In order to make the information in the positioning fingerprint database of the second network standard constructed more comprehensive, so that the terminal to be positioned under the second network standard can be positioned from multiple different angles, the first in this embodiment When the signal is an uplink reference signal or a downlink reference signal, the construction module 903 may also use the second signal of the second network standard to establish a positioning fingerprint library. At this time, the construction module 903 may be used to: obtain the second signal and the first signal in the second cell Signal mapping relationship; and according to the mapping relationship between the second signal and the first signal in the second cell, the first signal in the second cell and the corresponding first signal in the first cell, and the first cell in the first cell The location information corresponding to a signal establishes an association relationship between the second signal in the second cell and the corresponding location information, and generates a positioning fingerprint database of the second network standard.

例如,一种示例中,构建模块903可以用于统计第二小区下的各终端在不同位置上所传输的上行参考信号的信号特征和各终端在各相应的位置上所传输的下行参考信号的信号特征,根据统计结果建立第二小区中的上行参考信号的信号特征与下行参考信号的信号特征的映射关系。For example, in an example, the construction module 903 may be used to count the signal characteristics of the uplink reference signals transmitted by the terminals in the second cell at different positions and the downlink reference signals transmitted by the terminals at the corresponding positions. For signal characteristics, a mapping relationship between the signal characteristics of the uplink reference signal and the signal characteristics of the downlink reference signal in the second cell is established according to the statistical results.

具体的来说,对于第二网络制式下各第二小区中的每一终端,当该终端在某一位置上时,应当统计该终端在该位置上与某一基站之间所传输的上行参考信号的信号特征,以及该终端在该位置上与该基站之间所传输的下行参考信号的信号特征。如此,就可以得到多个上行参考信号的信号特征与下行参考信号的信号特征的对应关系,然后对得到的多个上行参考信号的信号特征与下行参考信号的信号特征的对应关系进行分析,得到上行参考信号的信号特征与下行参考信号 的信号特征的映射关系。Specifically, for each terminal in each second cell under the second network standard, when the terminal is at a certain location, the uplink reference transmitted between the terminal and a certain base station at that location should be counted The signal characteristics of the signal and the signal characteristics of the downlink reference signal transmitted between the terminal and the base station at the location. In this way, the correspondence between the signal characteristics of multiple uplink reference signals and the signal characteristics of downlink reference signals can be obtained, and then the correspondence between the obtained signal characteristics of multiple uplink reference signals and the signal characteristics of downlink reference signals is analyzed to obtain The mapping relationship between the signal characteristics of the uplink reference signal and the signal characteristics of the downlink reference signal.

在一些实施例中,可以基于概率分布来建立上行参考信号的信号特征和下行参考信号的信号特征的映射关系。具体的,构建模块903可以针对第二网络制式下的各第二小区的上行参考信号的每一信号特征的取值,确定出与其对应的出现概率最高的下行参考信号的信号特征的取值;或者,针对第二网络制式下的各第二小区的下行参考信号的每一信号特征的取值,确定出与其对应的出现概率最高的上行参考信号的信号特征的取值。In some embodiments, the mapping relationship between the signal characteristics of the uplink reference signal and the signal characteristics of the downlink reference signal may be established based on the probability distribution. Specifically, the construction module 903 may determine the value of the signal characteristic of the downlink reference signal with the highest occurrence probability corresponding to the value of each signal characteristic of the uplink reference signal of each second cell under the second network standard; Alternatively, for each signal characteristic value of the downlink reference signal of each second cell under the second network standard, the signal characteristic value of the uplink reference signal corresponding to the highest occurrence probability is determined.

如此得到的第二网络制式的定位指纹库中就包括上行参考信号的信号特征、下行参考信号的信号特征与位置信息之间的映射关系,从而在定位阶段,就可以根据待定位终端的上行参考信号的信号特征和/或下行参考信号的信号特征在定位指纹库中进行匹配,以确定待定位终端的位置。The positioning fingerprint database of the second network standard thus obtained includes the mapping relationship between the signal characteristics of the uplink reference signal, the signal characteristics of the downlink reference signal and the position information, so that in the positioning stage, the uplink reference of the terminal to be positioned can be based on The signal characteristics of the signal and/or the signal characteristics of the downlink reference signal are matched in the positioning fingerprint database to determine the location of the terminal to be positioned.

Referring to FIG. 10, the positioning device according to an embodiment of the present disclosure includes a second acquisition module 904 and a positioning module 905. The second obtaining module 905 is used to obtain the signal characteristics of the signal (which may be an uplink reference signal or a downlink reference signal) transmitted in the second cell corresponding to the location of the terminal to be located under the second network standard. The positioning module 905 is configured to determine corresponding position information as the positioning result of the terminal to be located according to the signal characteristics of the signal transmitted in the second cell and the positioning fingerprint database of the second network standard.

This method of establishing a cross-network fingerprint library solves such problems That is, when the signal characteristics under the second network standard cannot be directly collected, the positioning fingerprint library corresponding to the second network standard cannot be established, nor can the terminal in the second network standard be located. In particular, through the directly collected The signal characteristics and position information under one network standard can establish the positioning fingerprint database corresponding to the first network standard and the positioning fingerprint database corresponding to the second network standard, eliminating the need to separately collect information for the two network standards, and improving the establishment of the positioning fingerprint database s efficiency.
