[0067] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] It should be noted that if Figure 1 As shown in the figure, the working principle of UWB (Ultra Wide-Band) indoor positioning is as follows: the UWB control center receives the angle, time, time difference, signal strength and other information collected from the node to be measured (terminal) forwarded by the UWB positioning base station. According to the information collected from the node to be measured, the corresponding positioning mechanism is determined; according to the determined positioning mechanism, the measurement data is converted into the specific positioning coordinates of the node to be measured with respect to a given coordinate system.

[0069] Node under test: refers to the node whose location information needs to be determined. There are two working modes of the node under test: transmitting signals or reflecting signals.

[0070] UWB positioning base station: It is the main part of the entire UWB wireless indoor positioning system. The UWB positioning base station integrates two modules: the transmitting signal and the receiving signal. In actual indoor positioning, when the node to be measured is in the transmitting signal mode, the UWB positioning base station calls the receiving signal module to receive the positioning related information transmitted from the node to be measured and forwards it to the UWB control center after simple processing; when the node to be measured is in the reflected signal mode, the UWB positioning base station calls the receiving module to receive the signal reflected by the node to be measured and then forwards it to the UWB control center.

[0071] like Figure 2 As shown in the figure, the positioning architecture diagram of the 5G wireless access network NG-RAN (The interface between the gNB and the5GCN-Radio Access Network), LMF (Location Management Function) is the positioning server, which is responsible for selecting the positioning method and triggering the corresponding positioning measurement, and calculating the final positioning result.

[0072] NG-RAN: can send positioning reference signals or perform positioning measurements based on positioning assistance data.

[0073] Terminal UE (User Equipment): can send a positioning reference signal, or perform positioning measurement based on positioning assistance data; or calculate a positioning result based on the measurement result.

[0074] The information between the positioning server and NG-RAN is transmitted through the new wireless NR positioning protocol A NRPPa, and the information between the positioning server and the terminal is transmitted through the long-term evolution LTE positioning protocol LPP protocol.

[0075] At present, the UWB positioning method cannot be supported in the fifth generation mobile communication system. To solve this problem, the embodiment of the present application provides a positioning method, device, network equipment, base station and storage medium, which sends a UWB positioning measurement request to an ultra-wideband UWB positioning base station, and the UWB positioning measurement request carries the terminal identification of the terminal to be located; receives the first measurement result sent by the UWB positioning base station, and the first measurement result is determined by the UWB positioning base station according to the terminal identification and the terminal corresponding to the terminal identification through interaction; according to the first measurement result, the position of the terminal corresponding to the terminal identification is determined, which can reduce the measurement time of the terminal, improve the terminal positioning accuracy, and achieve rapid positioning. The positioning method, device, network equipment, base station and storage medium provided by the present application will be explained and illustrated in detail through specific embodiments.

[0076] It should be noted that in the following description, since the method and the device are based on the same application concept and the principles of solving the problem are similar, the implementation of the device and the method can refer to each other and the repeated parts will not be repeated.

[0077] In addition, it should be noted that the technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems.

In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network.

Since the terminal equipment and other network equipment (such as core network equipment and access network equipment (i.e., base station)) together constitute a network that can support communication, in the present invention, the terminal equipment is also regarded as a network equipment.

[0079] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services for the terminal, or a CU (Central Unit) or a DU (Distributed Unit). Depending on the specific application scenario, the network device may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0080] In addition, it should be understood that the term "and / or" in the embodiments of the present application describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0081] The references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the "in one embodiment" or "in an embodiment" that appear throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0082] The present application is described in detail below.

[0083] like Figure 3 As shown, it is a flowchart of the steps of a positioning method applied to a positioning server provided in an embodiment of the present application, and the method includes the following steps:

[0084] Step 101: Sending an ultra-wideband (UWB) positioning measurement request to an ultra-wideband (UWB) positioning base station, wherein the UWB positioning measurement request carries a terminal identifier of a terminal to be positioned.

[0085] In an embodiment of the present application, when the positioning server determines to provide UWB positioning service to the terminal, it can send a UWB positioning measurement request carrying the terminal identification of the terminal to be located to the UWB positioning base station within the coverage range through the new wireless NR positioning protocol ANRPPa message, so as to provide positioning service to the terminal through the UWB base station.

[0086] Step 102: Receive a first measurement result sent by the UWB positioning base station, where the first measurement result is determined by the UWB positioning base station through interaction with a terminal corresponding to the terminal identifier according to the terminal identifier.

[0087] In the embodiment of the present application, after receiving the UWB positioning signal sent by the UWB positioning base station, the terminal reflects or transmits the UWB positioning signal according to its own working mode. The UWB positioning base station performs measurement after receiving the positioning signal and reports the relevant measurement result (first measurement result) to the positioning server through the NRPPa measurement response message.

[0088] In this step, the UWB positioning measurement request is sent to the UWB positioning base station through the positioning server, so that the UWB positioning base station can send the positioning signal to the terminal according to the positioning measurement request, thereby reducing the time for the terminal to search for the UWB positioning signal. The positioning server receives the measurement results obtained by the UWB positioning base station based on the positioning signal reflected or transmitted by the terminal, and determines the terminal position according to the measurement results.

[0089] Step 103: Determine the location of the terminal corresponding to the terminal identifier according to the first measurement result.

[0090] In this step, after receiving the first measurement result sent by the UWB positioning base station, the positioning server determines the specific positioning coordinates of the terminal corresponding to the terminal identifier according to the first measurement result.

[0091] The positioning method provided in the embodiment of the present application sends a UWB positioning measurement request to the UWB positioning base station through the positioning server, so that the UWB positioning base station can obtain a first measurement result according to the positioning measurement request, and then determine the position of the terminal according to the first measurement result. It can be seen that the embodiment of the present application introduces UWB positioning technology into the 5G network, so that the terminal can obtain the positioning service provided by the UWB base station, thereby realizing rapid positioning.

[0092] Based on the content of the above embodiment, in this embodiment, sending a UWB positioning measurement request to an ultra-wideband UWB positioning base station includes:

[0093] Receiving a positioning request sent by a terminal, wherein the positioning request includes a terminal identifier of a terminal to be positioned;

[0094] Determine whether the terminal corresponding to the terminal identifier has UWB positioning capability;

[0095] If it is determined that the terminal has the UWB positioning capability, a UWB positioning measurement request is sent to the UWB positioning base station.

[0096] In this embodiment, the positioning server receives a positioning request sent by the terminal, and then the positioning server may configure a positioning method and a measurement configuration for the terminal according to the positioning capability supported by the terminal.

[0097] Based on the content of the above embodiment, in this embodiment, determining whether the terminal corresponding to the terminal identifier has the UWB positioning capability specifically includes:

[0098] Sending a positioning capability acquisition request to a terminal corresponding to the terminal identifier, wherein the positioning capability acquisition request is used to request the terminal to report the positioning capabilities supported by the terminal;

[0099] receiving a positioning capability response sent by the terminal;

[0100] Determine whether the terminal has UWB positioning capability according to the positioning capability response.

[0101] In this embodiment, the positioning server requests the terminal for the relevant capabilities of the UWB positioning method through an LPP capability request message. The requested relevant capability information may include whether the terminal itself supports the UWB positioning method and the working mode (reflection mode or transmission mode) of the terminal when using the UWB positioning method, that is, whether the terminal has the UWB positioning capability. After receiving the LPP capability request message sent by the positioning server, the terminal sends a positioning capability response to the positioning server through an LPP provision capability message. The positioning capability response is used to provide the positioning server with the capability of whether the terminal itself supports the UWB positioning method. After receiving the positioning capability response sent by the terminal, the positioning server determines whether the terminal has the UWB positioning capability according to the positioning capability response. If so, it sends a UWB positioning measurement request to the UWB positioning base station.

[0102] Based on the content of the above embodiment, in this embodiment, before sending the UWB positioning measurement request to the UWB positioning base station, the method further includes:

[0105] If it is determined that the terminal has the UWB positioning capability, UWB positioning assistance data is sent to the terminal, where the UWB positioning assistance data includes a UWB positioning signal and a UWB positioning method.

[0106] In this embodiment, before sending a UWB positioning measurement request to the UWB positioning base station, the positioning server may provide the positioning assistance data of the UWB positioning base station to the terminal, so that the terminal performs reflection or transmission according to the UWB positioning assistance data provided by the positioning server.

[0107] Specifically, after receiving the positioning assistance data acquisition request sent by the positioning server, the UWB positioning base station sends the relevant positioning assistance data to the positioning server, and the positioning server sends the positioning assistance data of the UWB positioning base station to the terminal through the Long Term Evolution LTE positioning protocol LPP message. Among them, the positioning assistance data of the UWB positioning base station may include the UWB positioning signal, the location information of the UWB positioning base station, the frequency range of the UWB positioning base station to transmit the UWB positioning signal, and the UWB positioning method requested by the positioning server.

[0108] Optionally, after determining that the terminal has UWB positioning capability, the positioning server sends UWB positioning assistance data to the terminal. The positioning assistance data of the UWB positioning base station may include the UWB positioning signal, the location information of the UWB positioning base station, the frequency range of the UWB positioning base station transmitting the UWB positioning signal, and the UWB positioning method requested by the positioning server.

[0109] Based on the content of the above embodiment, in this embodiment, before sending a UWB positioning measurement request to an ultra-wideband UWB positioning base station, the method further includes:

[0110] A positioning assistance data acquisition request sent by a receiving terminal is used to request positioning assistance data of a UWB base station that can provide a UWB positioning service, and the positioning assistance data acquisition request carries a terminal identifier of the terminal to be located;

[0111] According to the positioning assistance data acquisition request, UWB positioning assistance data is sent to the terminal corresponding to the terminal identifier, wherein the UWB positioning assistance data includes a UWB positioning signal and a UWB positioning method.

[0112] In this embodiment, the transmission process of the UWB positioning assistance data may be a positioning assistance data transmission process actively initiated by the positioning server, or may be a positioning assistance data transmission process actively initiated by the terminal.

[0113] Specifically, the terminal can actively initiate a positioning assistance data request process. The terminal determines the type of UWB positioning assistance data required and sends it to the positioning server through an LPP request assistance data message. The request message carries the terminal identifier corresponding to the terminal, and the request message includes an indication of the type of UWB positioning assistance data required by the terminal. If the positioning server receives the positioning assistance data acquisition request actively sent by the terminal, if it is determined that the positioning assistance data requested by the terminal in this server is available, the positioning server provides UWB positioning assistance data to the terminal through an LPP provision assistance data message, and the UWB positioning assistance data includes a UWB positioning signal and a UWB positioning method.

[0114] Based on the content of the above embodiments, in this embodiment, the ultra-wideband UWB positioning base station is located inside a base station of a mobile communication system or outside a base station of a mobile communication system.

[0115] Based on the content of the above embodiment, in this embodiment, receiving the positioning assistance data acquisition request actively sent by the terminal includes:

[0116] A positioning assistance data acquisition request is received, which is sent by the terminal through an LPP request assistance data message.

[0117] In this embodiment, the positioning server may receive a positioning assistance data acquisition request actively sent by the terminal through an LPP request assistance data message.

[0118] Based on the content of the above embodiment, in this embodiment, according to the positioning assistance data acquisition request actively sent by the terminal, sending the positioning assistance data to the terminal includes:

[0119] According to the positioning assistance data acquisition request actively sent by the terminal, the positioning assistance data is sent to the terminal through an LPP provide assistance data message.

[0120] In this embodiment, it should be noted that after receiving the positioning acquisition request actively sent by the terminal, if the positioning server determines that the positioning assistance data requested by the terminal in the server is available, the positioning server provides the terminal with positioning assistance data through an LPP providing assistance data message.

[0121] like Figure 4 As shown, it is a flowchart of the steps of the positioning method applied to the UWB positioning base station provided in the embodiment of the present application, and the method includes the following steps:

[0122] Step 201: receiving an ultra-wideband UWB positioning measurement request sent by a positioning server, wherein the UWB positioning measurement request carries a terminal identifier of a terminal to be positioned;

[0123] In this step, the UWB positioning base station receives a UWB positioning measurement request sent by the positioning server and carrying the terminal identification of the terminal to be positioned. The UWB positioning measurement request is used by the UWB positioning base station to send a UWB positioning signal to the terminal according to the UWB positioning measurement request.

[0124] Step 202: According to the UWB positioning measurement request, interact with the terminal corresponding to the terminal identifier to obtain a first measurement result;

[0125] In this step, after receiving the UWB positioning measurement request sent by the positioning server, the UWB positioning base station sends a UWB positioning signal to the terminal according to the UWB positioning measurement request, and the terminal reflects or transmits the UWB positioning signal to the UWB positioning base station. After receiving the UWB positioning signal reflected or transmitted by the terminal, the UWB positioning base station performs measurement to obtain a first measurement result.

[0126] Step 203: Send the first measurement result to the positioning server.

[0127] In this step, after obtaining the first measurement result, the UWB positioning base station reports it to the positioning server through an NRPPa measurement response message, and the positioning server calculates the terminal position according to the measurement result reported by the UWB positioning base station.

[0128] The positioning method, device, network equipment, base station and storage medium provided in the embodiments of the present application send a UWB positioning measurement request to the UWB positioning base station through a positioning server, so that the UWB positioning base station can send a positioning signal to the terminal according to the positioning measurement request, thereby reducing the time for the terminal to search for the UWB positioning signal. Furthermore, the embodiments of the present application also receive the measurement results obtained by the UWB positioning base station based on the positioning signal reflected or emitted by the terminal through the positioning server, and determine the terminal position based on the measurement results. It can be seen that the embodiments of the present application introduce UWB positioning technology into the 5G network, so that the terminal can obtain the positioning service provided by the UWB base station, thereby achieving rapid positioning.

[0129] Based on the content of the above embodiment, in this embodiment, sending the first measurement result to the positioning server specifically includes:

[0130] receiving a measurement result acquisition request sent by the positioning server, and sending the first measurement result to the positioning server according to the measurement result acquisition request;

If the reporting characteristic between the UWB positioning base station and the positioning server is periodic reporting, the UWB positioning base station first feeds back a measurement response message without any measurement results to the positioning server. Subsequent reporting is performed according to the period required by the positioning server. If the previously requested measurement result can no longer be reported, the UWB base station notifies the positioning server through a measurement failure indication message.

[0134] Based on the content of the above embodiment, in this embodiment, before receiving the ultra-wideband UWB positioning measurement request sent by the positioning server, the method further includes:

[0137] In this embodiment, it should be noted that before the UWB positioning base station receives the ultra-wideband UWB positioning measurement request sent by the positioning server, it also includes: receiving the positioning assistance data acquisition request sent by the positioning server through the long-term evolution LTE positioning protocol LPP message, and after receiving the positioning assistance data acquisition request sent by the positioning server, the UWB positioning base station sends the relevant positioning assistance data to the positioning server, and the positioning server sends the positioning assistance data of the UWB positioning base station to the terminal through the long-term evolution LTE positioning protocol LPP message. Among them, the positioning assistance data of the UWB positioning base station may include the location information of the UWB positioning base station, the frequency range of the UWB positioning base station transmitting the UWB positioning signal, and the measurement method requested by the positioning server.

[0140] Based on the content of the above embodiment, in this embodiment, sending the measurement result to the positioning server includes:

[0141] The measurement result is sent to the positioning server via the NRPPa message.

[0142] In this embodiment, after obtaining a measurement result of the UWB positioning signal reflected or transmitted by the terminal, the UWB positioning base station sends the measurement result to the positioning server through an NRPPa measurement response message.

[0143] like Figure 5 As shown, a flowchart of a positioning method applied to a terminal provided in an embodiment of the present application includes the following steps:

[0144] Step 301: receiving an ultra-wideband UWB positioning signal, where the UWB positioning signal is sent by a UWB positioning base station according to a UWB positioning measurement request sent by a positioning server;

[0145] In this step, it should be noted that the terminal receives the UWB positioning signal generated by the UWB positioning base station according to the UWB positioning measurement request sent by the positioning server.

[0146] Step 302: Reflect or transmit the UWB positioning signal to a UWB positioning base station, and the UWB positioning base station performs measurement based on the UWB positioning signal to obtain a measurement result.

[0147] In this step, it should be noted that after receiving the UWB positioning signal sent by the UWB positioning base station, the terminal reflects or transmits the UWB positioning signal according to its own working mode. After receiving the positioning signal, the UWB positioning base station performs measurement to obtain the measurement result, and reports the relevant measurement result to the positioning server through the NRPPa measurement response message. The positioning server calculates the terminal position based on the measurement result reported by the UWB positioning base station.

[0148] The positioning method, device, network equipment, base station and storage medium provided in the embodiments of the present application send a UWB positioning measurement request to the UWB positioning base station through a positioning server, so that the UWB positioning base station can send a positioning signal to the terminal according to the positioning measurement request, thereby reducing the time for the terminal to search for the UWB positioning signal. Furthermore, the embodiments of the present application also receive the measurement results obtained by the UWB positioning base station based on the positioning signal reflected or emitted by the terminal through the positioning server, and determine the terminal position based on the measurement results. It can be seen that the embodiments of the present application introduce UWB positioning technology into the 5G network, so that the terminal can obtain the positioning service provided by the UWB base station, thereby achieving rapid positioning.

[0150] Receiving positioning assistance data sent by the UWB positioning base station;

[0151] The UWB positioning signal is reflected or transmitted to a UWB positioning base station according to the positioning assistance data.

[0152] In this embodiment, before the positioning server sends a UWB positioning measurement request to the UWB positioning base station, it is necessary to first provide the positioning assistance data of the UWB positioning base station to the terminal, so that the terminal can reflect or transmit according to the UWB positioning assistance data provided by the positioning server. Specifically, after receiving the positioning assistance data acquisition request sent by the positioning server, the UWB positioning base station sends the relevant positioning assistance data to the positioning server, and the positioning server sends the positioning assistance data of the UWB positioning base station to the terminal through the Long Term Evolution LTE positioning protocol LPP message. Among them, the positioning assistance data of the UWB positioning base station may include the location information of the UWB positioning base station, the frequency range of the UWB positioning base station transmitting the UWB positioning signal, and the measurement method requested by the positioning server.

[0153] Based on the contents of the above embodiments, in this embodiment, it also includes:

[0154] The present application is described in detail below through specific embodiments.

[0155] First embodiment:

[0156] In this embodiment, if Figure 6 As shown, it is a schematic diagram of the positioning server and the terminal exchanging positioning assistance data through LPP messages in an embodiment of the present application. The positioning server will request the terminal for relevant capabilities of the UWB positioning method through the LPP capability request message. The requested capability information may include whether the terminal itself supports the UWB positioning method. The terminal provides its own capabilities to the positioning server through the LPP provision capability message, which may include whether the terminal itself supports the UWB positioning method, and the working mode (reflection mode or transmission mode) of the terminal when using the UWB positioning method.

[0157] Second embodiment:

[0158] In this embodiment, if Figure 7 As shown, it is a schematic diagram of the positioning server and the terminal exchanging positioning assistance data through LPP messages in an embodiment of the present application. The UWB positioning assistance data transmission process is divided into a positioning assistance data transmission process actively initiated by the positioning server and a positioning assistance data transmission process initiated by the terminal.

[0159] Positioning assistance data transmission process initiated by the positioning server:

[0160] The positioning server can decide which positioning assistance data to provide to the terminal and send it to the terminal through the LPP positioning assistance data message. The positioning assistance data includes the location information UWB of the UWB positioning base station, the frequency range of the UWB positioning base station transmitting signal, and the measurement method requested by the positioning server.

[0161] UWB positioning assisted data transmission process initiated by the terminal:

[0162] When the positioning assistance data provided by the positioning server is not sufficient for the terminal to complete the UWB call request, the terminal can actively initiate the positioning assistance data request process. The terminal determines the type of UWB positioning assistance data required and sends it to the positioning server via the LPP request assistance data message. This message includes an indication of the type of UWB positioning assistance data required by the terminal.

[0163] If the requested positioning assistance data is available in the positioning server, the positioning server provides the positioning assistance data to the terminal through an LPP provide assistance data message.

[0164] Third embodiment:

[0165] In this embodiment, if Figure 8 As shown, it is a schematic diagram of data interaction between the positioning server and the UWB positioning base station through NRPPa messages in an embodiment of the present application.

[0166] Step 1: The positioning server may request UWB-related measurement information from the UWB positioning base station through an NRPPa measurement request message.

[0167] Step 2: If the reporting feature in step 1 is set to "request reporting", the UWB positioning base station obtains the measurement result by measuring the positioning signal reflected or transmitted by the terminal, and sends the result to the positioning server through the NRPPa measurement response message.

[0168] Step 3: If the reporting feature in step 1 is set to "periodic reporting", the UWB positioning base station first feeds back a measurement response message without any measurement results to the positioning server. Subsequent reports are made according to the period required by the positioning server. If the previously requested measurement results can no longer be reported, the UWB positioning base station notifies the positioning server through a measurement failure indication message.

[0169] Step 4: At any time after step 2, the positioning server can update the information required for the UWB positioning base station measurement through the NRPPa measurement update message. After receiving the NRPPa measurement update message, the UWB positioning base station overwrites the previous information.

[0170] Step 5: The positioning server may terminate the ongoing measurement task through the NRPPa measurement termination message.

[0171] Fourth embodiment:

[0172] In this embodiment, if Fig. 9 As shown, it is a flowchart of the positioning server determining the terminal position provided in an embodiment of the present application. Through the LPP capability interaction process, the positioning server obtains the UE capability.

[0173] The positioning server provides the terminal with relevant auxiliary information for obtaining UWB positioning signals through the LPP assisted data transmission process.

[0174] The positioning server requests the UWB positioning base station to perform UWB positioning measurement through the NRPPa message. (Whether the UWB access point is in the communication base station or not, communication can be carried out through the NRPPa interface).

[0175] The UWB positioning base station sends a UWB positioning signal to the terminal.

[0176] The terminal transmits or reflects the UWB positioning signal according to whether it has a UWB transmitting module.

[0177] The UWB positioning base station performs measurements after receiving the positioning signal and reports the relevant measurement results to the positioning server through the NRPPa measurement response message.

[0178] The positioning server calculates the terminal location through the measurement information reported by the UWB positioning base station.

[0179] It can be seen that the embodiment of the present application implements some functions of the UWB control center through the positioning server of the mobile communication system (for example: positioning server), and provides the UWB positioning assistance data to the positioning terminal through the mobile communication system. The positioning terminal reflects the UWB signal of the UWB positioning base station or sends the signal to the UWB positioning base station according to the UWB positioning assistance data provided by the mobile communication system. The UWB positioning base station feeds back the relevant measurement results to the positioning server of the mobile communication system, and the positioning server performs position solution according to the measurement results provided by the UWB positioning base station. Specifically, the UWB positioning method uses the measurement values ​​of the UWB positioning base station (UWB positioning base station identifier and other optional measurement quantities) and the positioning server of the mobile communication system to determine the location of the terminal. The UWB positioning base station can be inside the base station of the mobile communication system or outside the base station of the mobile communication system. The terminal transmits or reflects the UWB positioning signal obtained from the UWB positioning base station to the UWB positioning base station, which performs measurement and forwards the measurement result to the mobile communication system positioning server. The mobile communication system positioning server calculates the position of the target terminal device, which can reduce the measurement time of the terminal, improve the terminal positioning accuracy, and increase the data transmission rate, especially in the case of indoor positioning.
