[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] Figure 1 A schematic diagram of an application scenario of a positioning method provided in an embodiment of the present application. Figure 1 As shown, in this scenario, there are a base station 101, an LMF (Location Management Function) 102, an extended location information device 103, an extended positioning measurement device 104, and a terminal 105. The base station 101, the LMF 102, and the extended location information device 103 transmit data to each other through the network, and the extended location information device 103 and the extended positioning measurement device 104 transmit data to each other through the network. The extended positioning measurement device 104 is used to measure the SRS (Sounding Reference Signal) sent by the terminal 105.

[0056] Among them, the base station 101 can be a base station (Base Transceiver Station, BTS) in Global System of Mobile communication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a base station in a 5G network, etc., which is not limited here.

[0057] LMF 102 is a network element of a core network in a wireless communication network, wherein the wireless communication network may be a global mobile communication or code division multiple access network, a wideband code division multiple access network, an LTE network, or a 5G network, which is not limited here.

[0058] The extended location information device 103 may be a device capable of parsing data uploaded by the base station 101 , the LMF 102 , and the extended positioning measurement device 104 .

[0059] The extended positioning measurement device 104 may be a device capable of receiving an SRS signal and performing measurement.

[0060] The terminal 105 may be a wireless terminal, which may be a device that provides voice and / or other service data connectivity to a user, or a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal may communicate with one or more core networks via a radio access network (Radio Access Network, referred to as RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network. The wireless terminal may also be referred to as a system, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile station (Mobile), a remote station (Remote Station), a remote terminal (Remote Terminal), an access terminal (Access Terminal), a user terminal (User Terminal), a user agent (User Agent), a user device (User Device or User Equipment), which is not limited here.

[0061] The 5G standard defines positioning technologies such as UTDOA, AOA, and RTT, but requires gNB (English: the nextGeneration Node B, Chinese: next generation base station) / pRRU (English: PicoRRU; skin base station) to support high-precision positioning signal transmission or measurement, time synchronization and other dedicated capabilities, resulting in the need for pRRU to increase additional hardware costs. When the site density is insufficient and additional sites are needed, the cost is even higher. In addition, although pRRU has been commercialized, the equipment support rate is low, the price is high, and the manufacturer's private protocols are difficult to interoperate. The positioning experience in the scenario of using radio frequency remote positioning is seriously reduced, which seriously affects the deployment and application of 5G integrated positioning technology and limits the integrated positioning advantages of operators' communication networks and the development of positioning ecology.

[0062] Based on the above problems, it is necessary to propose effective technical means to solve them. The technical solution of the present application and how the technical solution of the present application solves the above technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0063] In one embodiment, Figure 2 As shown, a positioning method is provided, which is applied to Figure 1 The following steps may be included:

[0064] Step 201: An extended positioning measurement device receives a first measurement request sent by an extended location information device.

[0065] Among them, the extended positioning measurement device and the extended location information device are both non-base station devices, the extended positioning measurement device is set on the access network side, and the first measurement request is sent by the extended location information device after receiving the second measurement request sent by the base station or LMF.

[0066] Extended positioning measurement equipment refers to the equipment newly added in the implementation of UTDOA positioning technology. It is loosely coupled with gNB and can use the power supply and transmission resources of gNB. For example, it can share the network cable with pRRU, but does not need to have direct information interaction with gNB. In addition, the English abbreviation of extended positioning measurement equipment can be XLU_UT.

[0067] Extended location information device also refers to the newly added device in the implementation of UTDOA positioning technology, which can be connected to multiple extended positioning measurement devices and connected to gNB / LMF at the same time. In addition, the English abbreviation of extended location information device can be XLIF.

[0068] In addition, the interaction between the extended positioning measurement device and the extended location information device can achieve nanosecond-level time synchronization.

[0069] The information included in the first test request may be part or all of the information included in the second test request. The protocol based on the first test request and the protocol based on the second test request may be the same or different, which is not limited here.

[0070] Optionally, in the UTDOA positioning process, LMF directly sends a second test request to the extended location information device, or LMF sends a second test request to the base station in an NRPPa (English: New Radio Positioning Protocol a) measurement request message, and then the base station sends the second test request to the extended location information device. After receiving the second test request, the extended location information device performs protocol conversion and other processing on the second test request to obtain the first test request, and then sends the first test request to the extended positioning measurement device, so that the extended positioning measurement device can receive the first measurement request sent by the extended location information device.

[0071] Step 202: The extended positioning measurement device measures the SRS signal sent by the target terminal to be positioned based on the first measurement request to obtain measurement data.

[0072] Optionally, the extended positioning measurement device receives an SRS signal sent by the target terminal at a specified time-frequency resource position and measures the SRS signal. There are two types of measurement data obtained, which are as follows:

[0073] The first type is that the measurement data includes the offset between the time when the extended positioning measurement device receives the SRS signal and the start time of the SRS reception time window, the signal strength and signal quality of the SRS signal received by the extended positioning measurement device, and the like.

[0074] The second type of measurement data includes RTOA (Relative Time of Arrival) data and / or RSCP (Received Signal Code Power) data of the SRS signal received by the extended positioning measurement device.

[0075] For how the extended positioning measurement device can obtain the above two types of measurement data, please refer to the following embodiment of measurement data, which will not be described in detail here.

[0076] Step 203, the extended positioning measurement device sends the measurement data to the extended location information device, so that the extended location information device obtains location information data according to the measurement data, and sends the location information data to the LMF, so that the LMF can perform positioning and solution on the target terminal according to the location information data.

[0077] The location information data includes RTOA data and / or RSCP data, etc.

[0078] Optionally, in step 202, since there are two types of measurement data, the extended location information device has different processing methods for different measurement data, that is, if the measurement data is the first type mentioned above, the extended location information device parses and calculates the measurement data to obtain the location information data; if the measurement data is the second type mentioned above, the extended location information device extracts the location information data from the measurement data.

[0079] After the extended positioning measurement device obtains the location information data, it sends the location information data directly to the LMF, or sends the location information data to the base station, and the base station reports the location information data to the LMF in the NRPPa measurement response message, so that the LMF can perform positioning and solution for the target terminal based on the location information data.

[0080] In the above positioning method, the first measurement request sent by the extended location information device is received by the extended positioning measurement device, wherein the extended positioning measurement device and the extended location information device are both non-base station devices, and the extended positioning measurement device is arranged on the access network side. The first measurement request is sent by the extended location information device after receiving the second measurement request sent by the base station or LMF, and then the extended positioning measurement device is used to measure the SRS signal sent by the target terminal to be located based on the first measurement request to obtain measurement data, and then the extended positioning measurement device is used to send the measurement data to the extended location information device, so that the extended location information device can obtain the location information data according to the measurement data, and send the location information data to the LMF, so that the LMF can locate the target terminal according to the location information data. Therefore, in the deployment of the positioning network, only the extended positioning measurement device needs to be added, and compared with the base station, the extended positioning measurement device only needs to be able to meet the measurement of the SRS signal, and its cost is relatively low. Therefore, the present application can reduce the cost of positioning network deployment, and there is no problem of low support rate, high price, and difficulty in intercommunication of manufacturer private protocols. It solves the problem of serious decline in positioning experience in the scenario of using radio frequency remote, thereby promoting the integrated positioning of the operator's communication network and the development of positioning ecology.

[0081] like Figure 3 As shown, a schematic diagram of a UTDOA positioning process is provided, including the following steps:

[0082] Step 300, LMF can use 3GPP TS 38.305V17.3.0 (2022-12) subclause 8.14.3.2 in Figure 8 .14.3.2.1-2 Obtain the TRP (Transmission and Receiving Point) configuration information required for UL-AoA (UpLink-Angle of Arrival) positioning.

[0083] In step 301, the LMF may use the LPP (Lightweight Presentation Protocol) capability transfer procedure described in subclause 8.14.3.1 of 3GPP TS 38.305 V17.3.0 (2022-12) to request the target terminal (such as Figure 3 The positioning capability of the UE shown.

[0084] Step 302, the LMF sends an NRPPa positioning information request message to the serving gNB of the UE to request the UE's UL-SRS configuration information, as specified in subclause 8.13.3.2 of 3GPP TS 38.305 V17.3.0 (2022-12) Figure 8 .As described in 14.3.2.1-1.

[0085] In step 303, the serving gNB determines the resources available for UL-SRS and configures the UE with a UL-SRS resource set at step 303a.

[0086] Step 304: The serving gNB provides UL information to the LMF in the NRPPa positioning information response message. In this way, the LMF obtains the UL-SRS configuration information for the UE.

[0087] Step 305 includes step 305a, step 305b and step 305c, wherein:

[0088] Step 305a, in the case of semi-persistent or aperiodic SRS, the LMF may request activation of UE-SRS transmission by sending an NRPPa positioning activation request message to the UE's serving gNB, as described in subclause 8.13.3.3a of 3GPP TS 38.305 V17.3.0 (2022-12).

[0089] Step 305b, the serving gNB activates UL-SRS transmission.

[0090] Step 305c: The serving gNB sends an NRPPa positioning activation response message, and the UE starts UL-SRS transmission according to the time domain behavior of the UL-SRS resource configuration.

[0091] Step 306, LMF sends a NRPPa measurement request message to the selected gNB (including Figure 3 The serving gNB and neighbor gNB as shown) provide UL-SRS configuration as described in subclause 8.14.3.3 of 3GPP TS 38.305 V17.3.0 (2022-12). This message includes all the information required by the gNB / TRP to perform UL measurements.

[0092] Step 307, each gNB configured in step 306 measures the UL-SRS transmission from the UE.

[0093] Step 308, each gNB reports the UL-SRS measurement results to the LMF in the NRPPa measurement response message, as described in subclause 8.14.3.3 of 3GPP TS38.305V17.3.0(2022-12).

[0094] Step 309, LMF sends an NRPPa positioning deactivation message to the serving gNB, as described in subclause 8.14.3.3a of 3GPP TS 38.305 V17.3.0 (2022-12)

[0095] In the above steps, the data sent through NRPPa includes at least one of the terminal configuration data (corresponding in English: UE configuration data), terminal resource configuration (corresponding in English: UE SRS configuration), TRP timing information of the terminal SRS transmission (corresponding in English: Timing information of the TRP, which configured the UE SRS transmission) and association information of SRS resources and transmitting end TEG (Timing RrroMitigation) identification code (corresponding in English: The association information of SRS resources with UE Tx TEG ID).

[0096] After the above step 305c, the LMF sends the second measurement request and the second SRS configuration information to the extended location information device instead, or, after the above step 306, the base station sends the second measurement request and the second SRS configuration information to the extended location information device instead, and the second SRS configuration information is the UL-SRS configuration information for the UE obtained by the LMF in the above step 304.

[0097] After receiving the second measurement request and the second SRS configuration information, the extended location information device sends the first measurement request and the first SRS configuration information to the extended positioning measurement device, so that the extended positioning measurement device implements the following embodiment according to the first measurement request and the first SRS configuration information. Among them, the first SRS configuration information can be part or all of the second SRS configuration information, for example, the first SRS configuration information can include the frequency band and SRS receiving time window in the second SRS configuration information, that is, the time-frequency resource position of the target terminal sending the SRS signal; the first SRS configuration information can also include the identification information, frequency band and SRS receiving time window of the target terminal in the second SRS configuration information.

[0098] In one of the embodiments, the method may also include: an extended positioning measurement device receives first SRS configuration information of the target terminal sent by the extended location information device; correspondingly, the extended positioning measurement device measures the SRS signal sent by the target terminal to be located based on the first measurement request to obtain measurement data, including: in response to the first measurement request, the extended positioning measurement device measures the SRS signal sent by the target terminal based on the first SRS configuration information to obtain measurement data.

[0099] Optional, such as Figure 4 As shown, a schematic diagram of a process of obtaining measurement data by an extended positioning measurement device is provided, including the following steps:

[0100] Step 401: The extended positioning measurement device determines an SRS receiving time window according to first SRS configuration information.

[0101] The SRS receiving time window can be a micron-level time period, such as [2×10 -3 , 3×10 -3 ].

[0102] Optionally, the extended positioning measurement device may extract the SRS receiving time window from the first SRS configuration information.

[0103] Step 402: The extended positioning measurement device measures the SRS signal received in the SRS reception time window to obtain measurement data.

[0104] Optionally, the target terminal sends an SRS signal with a nanometer time step on the time-frequency resources configured for it by the base station, that is, the target terminal sends an SRS signal with a nanometer time step within a time period corresponding to the SRS reception time window, so that the extended positioning measurement device can receive multiple SRS signals sent by the target terminal within the SRS reception time window, and record them to obtain measurement data.

[0105] For example, the target terminal is in the 5G frequency band 100M, with a time step of 1×10-6 In the time period [2×10 -3 , 3×10 -3 ] to send SRS signals, the extended positioning measurement equipment can be in the 100M frequency band of 5G, in [2×10 -3 , 3×10 -3 ]Several SRS signals are received within the SRS receiving time window and recorded to obtain measurement data.

[0106] The measurement data obtained by the extended positioning measurement device can be of the following types. For each type of measurement data, the corresponding extended location information device has a different processing method to obtain the location information data, as shown below.

[0107] First, the measurement data may include multiple SRS data, and the SRS data include the offset between the time when the extended positioning measurement device receives the SRS signal and the start time of the SRS reception time window, and the signal strength and signal quality of the SRS signal received by the extended positioning measurement device.

[0108] The extended positioning measurement device sends the measurement data to the extended location information device, which may include: the extended positioning measurement device sends the measurement data to the extended location information device via a baseband signal.

[0109] Correspondingly, the extended location information device obtains the identification information of the target terminal according to the second SRS configuration information and queries the measurement data from the database, in which the measurement data corresponding to multiple different terminals are stored.

[0110] The extended location information device obtains location information data based on the measurement data and sends the location information data to the LMF, which may include: for each SRS data in the measurement data, the extended location information device obtains RTOA data based on the offset and obtains RSCP data based on the signal strength; the extended location information device sends the RTOA data and RSCP data corresponding to each SRS data as location information data to the LMF.

[0111] The SRS data refers to the SLOT data of the SRS signal. The start time of the SRS reception time window is not fixed, but is the transmission time of the SRS signal configured by the base station for the target terminal. Therefore, for each SRS signal sent by the target terminal, there is a corresponding start time of the SRS reception time window.

[0112] The recording format of the SRS signal by the extended positioning measurement equipment is as follows:

[0113] For the SRS data corresponding to the i-th SRS signal, including T i +t i , where T iis the sending time of the SRS signal configured by the base station for the target terminal, that is, the starting time of the RS receiving time window, t i is the propagation delay caused by the distance between the target terminal and the extended positioning measurement device, that is, the offset between the SRS signal timing and the start time of the SRS reception time window. When the distance between the target terminal and the extended positioning measurement device is about 30m, t i The SRS data corresponding to the ith SRS signal also includes the signal strength and signal quality of the SRS signal.

[0114] After the extended positioning measurement device sends the first measurement data to the extended location information device via a baseband signal, the extended location information device filters the baseband signal and stores it in a database. When the extended location information device needs to calculate the measurement data, it performs the following operations.

[0115] Because the database may store measurement data corresponding to multiple different terminals, the extended location information device needs to first query the measurement data of the target terminal according to the SRS reception time window in the second SRS configuration information. Then, for the SRS data corresponding to the i-th SRS signal, the extended location information device calculates T according to the SRS reception time window in the second SRS configuration information. i , so that the location information device can be extended according to the SRS receiving time window and T i Extracted from the measured data i , and then according to t i By converting the format of the system time, RTOA data can be obtained, and / or RSCP data can be obtained according to the signal strength. The SRS data corresponding to all SRS signals are processed as above to obtain the location information data.

[0116] The extended location information device then sends the location information data and the identification information of the target terminal to the LMF according to the terminal identification of the target terminal in the second SRS configuration information, so that the LMF can perform positioning calculation on the target terminal according to the location information data. The identification information of the terminal can be the ID of the terminal.

[0117] Second, the measurement data may include a plurality of SRS data, where the SRS data includes RTOA data and / or RSCP data of an SRS signal received by the extended positioning measurement device.

[0118] Correspondingly, the extended location information device queries the measurement data and the identification information of the target terminal from the database according to the second SRS configuration information.

[0119] The extended location information device extracts location information data from the measurement data and sends the location information data to the LMF.

[0120] Among them, for each received SRS signal, the extended positioning measurement device still records the offset between the time when the SRS signal is received and the start time of the SRS receiving time window, the signal strength and signal quality of the SRS signal received by the extended positioning measurement device in the above manner, and then the extended positioning measurement device calculates RTOA data according to the offset, and / or calculates RSCP data according to the signal strength. All SRS signals are processed as above to obtain measurement data.

[0121] Because the database may store measurement data corresponding to multiple different terminals, the extended location information device needs to first query the measurement data of the target terminal according to the SRS receiving time window in the second SRS configuration information. Then the extended location information device extracts the location information data from the measurement data, and sends the identification information and location information data of the target terminal to the LMF according to the terminal identification of the target terminal in the second SRS configuration information, so that the LMF can locate the target terminal according to the location information data.

[0122] The third type is that the measurement data includes identification information of the target terminal and multiple SRS data, and the SRS data includes RTOA data and / or RSCP data of the SRS signal received by the extended positioning measurement device.

[0123] Correspondingly, the extended location information device extracts location information data from the measurement data and sends the location information data to the LMF.

[0124] Among them, the first SRS configuration information also includes the identification information of the target terminal in the second SRS configuration information. When the extended positioning measurement device measures the SRS signal received in the SRS receiving time window according to the first SRS configuration information and obtains multiple SRS data including RTOA data and / or RSCP data, the identification information of the target terminal and the multiple SRS data are sent to the extended location information device as measurement data.

[0125] The extended location information device can directly extract the location information data and the identification information of the target terminal from the measurement data, and then send the identification information and location information data of the target terminal to the LMF, so that the LMF can locate the target terminal according to the location information data.

[0126] In this embodiment, for the first and second measurement data, the extended positioning measurement device does not need to know the identification information of the target terminal, etc., which can reduce the processing complexity of the extended positioning measurement device in data configuration, measurement, etc., and has low hardware requirements, thereby further reducing the cost of the extended positioning measurement device. For the third measurement data, the cost of the extended location information device can be further reduced.

[0127] In summary, the advantages of this application are as follows:

[0128] 1. Due to the independent settings of positioning-related measurement units, gNB / pRRU only needs to support a small number of configuration data interface functions, which has low requirements for gNB, making it easier to lower the implementation threshold for manufacturers and improve equipment support rate.

[0129] 2. When there is a positioning blind spot and a site needs to be added, only a simple extended positioning measurement device needs to be calibrated instead of the entire pRRU, and the single cost is reduced from thousands of yuan to hundreds of yuan.

[0130] 3. For passive indoor distribution and digital indoor distribution scenarios without positioning measurement hardware, this application can also be used to upgrade and achieve positioning.

[0131] 4. The RTOA data and / or RSCP data of each target terminal is uniformly processed by the extended location information device instead of being measured by the extended positioning measurement device. The extended positioning measurement device may not know the target terminal ID and other information, which can reduce the processing complexity of the extended positioning measurement device in data configuration, measurement, etc., thereby reducing the implementation cost of the extended positioning measurement device.

[0132] In one embodiment, Figure 5 As shown, another positioning method is provided, which is applied to Figure 1 The following steps may be included:
