[0042] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] UWB positioning boasts strong anti-interference capabilities and high accuracy, making it widely used in material tracking and positioning. Currently, UWB base stations require network connections, network routing configuration, and management, resulting in high gateway and network costs. Furthermore, solutions based on user-plane protocol transmission consume high power consumption in user devices, making current positioning methods highly dependent on hardware resources.

[0044] Based on this, the present application obtains the positioning configuration information of the user equipment through the positioning processing unit, and sends a positioning instruction to the user equipment based on the positioning configuration information through the base station. The user equipment only needs to obtain the positioning reference information, and the positioning processing unit performs positioning based on the positioning reference information, thereby eliminating the need to independently build a positioning base station, reducing dependence on hardware resources, and also reducing positioning costs.

[0045] The positioning method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown, the UE (User Equipment) connects to the NG-RAN (Next Generation Radio Access Network) via the NR-Uu interface and the LTE-Uu interface. The base station includes the gNB (next generation Node B, 5G base station) and the ng-eNB (next generation eNB, next generation LTE base station). The gNB and ng-eNB are connected via the Xn interface. The gNB includes multiple TRPs (Transmission and Reception Points), and the ng-eNB includes multiple TPs (Transmission Points). A TRP is an antenna or transmission unit within the gNB, responsible for signal transmission and reception, enabling more accurate positioning measurements.

[0046] The UE is equipped with a Secure User Equipment for Location Services (SET) module to support positioning parameter collection. The UE connects to the gNB via the NR-Uu interface, and to the ng-eNB via the LTE-Uu interface. The base station communicates with the LMF (Location Management Function) via the AMF (Access and Mobility Management Function). The ng-eNB and gNB connect to the AMF via the NG-C interface, and the AMF connects to the LMF via the NL1 interface.

[0047] The positioning processing unit sends positioning configuration information to the base station through the AMF. The base station sends positioning instructions to the user equipment based on the NR-Uu interface. The user equipment collects positioning parameter information through the positioning module and returns it to the base station. The base station then returns the positioning parameter information to the positioning processing unit for positioning the user equipment. The positioning processing unit can also be connected to external platforms or systems that assist in positioning, including but not limited to E-SMLC (Evolved Serving Mobile Location Center) and SLP (Secure Location Platform), for specific service scenarios or more advanced positioning calculations.

[0048] User devices include, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices include smart speakers, smart TVs, smart air conditioners, smart car devices, and projectors. Portable wearable devices include smart watches, smart bracelets, and head-mounted devices. Head-mounted devices can include virtual reality (VR) devices, augmented reality (AR) devices, and smart glasses. The gNB is the primary base station in the 5G network, providing wireless access. The TRP is the antenna or transmission unit within the gNB, responsible for signal transmission and reception, enabling more accurate positioning measurements. The ng-eNB is an enhanced base station supporting LTE connections and can collaborate with the 5G network for positioning. The LMF and AMF are core network components. The LMF coordinates and controls the positioning process, including communicating with base stations, allocating positioning resources, collecting measurement results, and calculating position. The AMF is responsible for access and mobility management, assisting the LMF in communicating with other network components during the positioning process. The NR-Uu interface is the radio interface between the UE and the gNB / TRP, used for the transmission of positioning signals, such as uplink SRS signals. The LTE-Uu interface is the radio interface between the UE and the ng-eNB, used to support the transmission of positioning signals in the LTE network. The Xn interface is the interface between the gNB and ng-eNB or other base stations, used for the coordination and sharing of positioning-related information, such as measurement data and resource allocation. The NG-C interface is the interface between the gNB / ng-eNB and the AMF, used for signaling and management functions in the core network, including positioning triggering and control. The NL1 interface is the interface between the LMF and the AMF, used for the exchange of positioning management signaling.

[0049] In an exemplary embodiment, Figure 2 As shown, a positioning method is provided, which is applied to Figure 1 The positioning processing unit in FIG. 1 is taken as an example to illustrate the method, which includes the following steps S202 to S206. Among them:

[0050] Step S202: Acquire positioning configuration information of the user equipment.

[0051] The user equipment may be a UE, and the user equipment may be a device that requires positioning. For example, UWB-based positioning may be performed. The positioning module in the user equipment may include a UWB scanning unit, which includes a UWB broadcast scanning module and an interface module. The UWB scanning unit is connected to the TRP of the base station via an external interface such as an RS232 interface or a USB interface, performs UWB broadcast scanning periodically or under conditions, and sends the scanning results to the TRP via the external interface. The scanning results of the UWB broadcast scanning performed by the user equipment via the UWB scanning unit may be positioning reference information.

[0052] To determine the positioning method of the user equipment, the positioning processing unit can obtain the user equipment's positioning configuration information. The positioning configuration information can include various information, such as the user equipment's positioning method and UWB positioning configuration parameters. The UWB positioning configuration parameters represent the specific method used by the user equipment to collect positioning parameter information.

[0053] The positioning processing unit can be a unit in the core network, responsible for interacting with the gNB and user equipment (UE) to complete control-plane UWB positioning process control and UWB+5G converged positioning process control, obtain positioning results, and output them. The positioning processing unit includes a UWB scanning message interaction module and a UWB+5G converged positioning module based on the NRPPa (NR Positioning Protocol A) interface. The gNB connects to multiple Transition Positioning Protocols (TRPs), which include a 5G signal measurement module, a UWB peripheral interface module (such as RS232 or USB), and an NRPPa interface module. The TRP sends UWB broadcast scanning results to the positioning processing unit via the extended NRPPa interface. The UWB broadcast scanning results represent positioning reference information for the user equipment. The user equipment is equipped with a UWB scanning unit, including a UWB broadcast scanning module and an interface module. This unit connects to the TRP via a peripheral interface such as RS232 or USB. Based on the positioning configuration information, the unit performs periodic or conditionally triggered UWB broadcast scanning and sends the scanning results, such as positioning reference information, to the TRP via the peripheral interface. The user equipment may be a UWB terminal UE, which may periodically send a UWB broadcast signal.

[0054] Step S204, sending the positioning configuration information to the base station; the positioning configuration information is used by the base station to send a corresponding positioning instruction to the user equipment; the positioning instruction is used to instruct the user equipment to obtain positioning reference information and send it to the base station.

[0055] The above-mentioned base station may be a base station within the range of the user equipment. The positioning processing unit LMF can establish an NRPPa connection with the base station gNB where the user equipment is located through the AMF at the request of the user equipment. The positioning processing unit can send the above-mentioned positioning configuration information to the base station. After receiving the positioning configuration information, the base station can send corresponding positioning instructions to the user equipment based on the positioning configuration information. For example, the base station determines the corresponding positioning mode and positioning method based on the positioning configuration information, and the base station sends a positioning instruction to the user equipment, instructing the user equipment on how to collect positioning reference information, such as periodic scanning or conditional trigger scanning, and how to collect positioning reference information, such as the collection steps and what information needs to be collected. After the user equipment obtains the positioning reference information based on the positioning instruction, it can send the positioning reference information to the base station. The base station can then return the above-mentioned positioning reference information to the positioning processing unit.

[0056] Specifically, the positioning processing unit sends an NRPPa message to the base station. The message type is "Measurent Request." The message also includes the "UWB" type, indicating a UWB positioning scan, as well as positioning configuration information, including the positioning mode, such as periodic scanning or conditional trigger scanning. The message also carries UWB positioning configuration parameters, such as the positioning method. The base station (gNB) controls the connected Transmission Relay Protocol (TRP) and sends positioning instructions to the user equipment's UWB module via the TRP's peripheral interface. For example, if a periodic scan is used, the base station sends a "Start Periodic Scan" message to the user equipment's UWB module. The user equipment uses its UWB module to transmit the periodic scan UWB broadcast results, such as positioning reference information, to the TRP via a peripheral interface. The TRP then sends the positioning reference information to the gNB. The gNB then sends the positioning reference information to the positioning processing unit via an NRPPa message in the form of a "Measurement Update" message, which carries the UWB broadcast scan results, such as the positioning reference information.

[0057] Step S206: Determine the positioning result corresponding to the user equipment according to the positioning reference information sent by the base station.

[0058] The positioning processing unit may locate the user equipment based on the positioning reference information sent by the base station, for example, performing UWB positioning based on the positioning reference message, etc. The positioning reference information may include multiple types of information.

[0059] In one embodiment, the positioning result corresponding to the above-mentioned user equipment is determined based on the above-mentioned positioning reference information sent by the above-mentioned base station, including: determining one or more of the media access control address, ultra-wideband communication signal strength, ultra-wideband communication signal timestamp, signal flight time and transmission power corresponding to the above-mentioned user equipment based on the above-mentioned positioning reference information; determining the positioning result corresponding to the above-mentioned user equipment based on one or more of the above-mentioned media access control address, the above-mentioned ultra-wideband communication signal strength, the above-mentioned ultra-wideband communication signal timestamp, the above-mentioned signal flight time and the above-mentioned transmission power.

[0060] In this embodiment, the positioning reference information collected by the user equipment includes, but is not limited to, one or more of the following: a media access control address corresponding to the user equipment, ultra-wideband communication signal strength, an ultra-wideband communication signal timestamp, a signal flight time, and a transmit power. The media access control address represents a MAC address, such as terminalMac (user equipment media access control address), which represents the MAC address of the UWB user equipment and can be expressed in the format of 00112233ABCD. The ultra-wideband communication signal strength can be RSSI (Received Signal Strength Indication), specifically the UWB signal strength received by the UWB indoor antenna from the UWB user equipment, and can be expressed in dBm. The ultra-wideband communication signal timestamp can be time, specifically the UWB signal timestamp received by the UWB indoor antenna from the UWB user equipment, and can be a string of digits. The signal flight time can be expressed as TOF (Time of Flight). The transmit power can be expressed as terminalPower (user equipment power), specifically the transmit power of the UWB user equipment, and can be expressed in dBm. In addition, in some embodiments, the above-mentioned positioning reference information may also include PDOA info (PhaseDifference of Arrival information, positioning information based on arrival phase difference), that is, the user equipment can receive phase difference information through multiple antennas; it may also include AOA (Angle of Arrival) information.

[0061] Therefore, the positioning processing unit can determine one or more of the media access control address, ultra-wideband communication signal strength, ultra-wideband communication signal timestamp, signal flight time and transmission power corresponding to the above-mentioned user equipment based on the above-mentioned positioning reference information, and perform UWB-based positioning on the user equipment based on the above-mentioned media access control address, the above-mentioned ultra-wideband communication signal strength, the above-mentioned ultra-wideband communication signal timestamp, the above-mentioned signal flight time and the above-mentioned transmission power to determine the positioning result corresponding to the above-mentioned user equipment.

[0062] Specifically, if Figure 3 As shown, Figure 3 This is a timing diagram of the positioning steps in one embodiment. The positioning processing unit (LMF) can establish communication with the base station (gNB) based on NRPPa messages. The positioning processing unit sends an NRPPa message to the base station. The message type is "Measurent Request." This message includes the type "UWB," indicating a UWB positioning scan, as well as positioning configuration information, including positioning methods such as periodic scanning or conditional trigger scanning. The message also carries UWB positioning configuration parameters, such as the positioning method. After receiving this message, the base station (gNB) can return a corresponding reception result to the positioning processing unit based on the NRPPa message, such as an NRPPa message of the type "Measurent Response" or "Failure." The base station controls the connected TRP and sends positioning instructions to the user equipment's UWB module via the TRP peripheral interface. For example, if a periodic scan is required, the base station sends a "Start Periodic Scan" message to the user equipment's UWB module. The user equipment uses the UWB module to periodically scan the UWB broadcast results, such as positioning reference information, and provides it to the TRP through the peripheral interface. The TRP sends it to the gNB, and the base station gNB uses the NRPPa information to form a Measurement Report (scan result) message to the positioning processing unit, which carries the UWB broadcast scan results, such as the above-mentioned positioning reference information.

[0063] The positioning processing unit may also send an NRPPa message of the message type Measurement Update to the base station to instruct the base station to update the positioning reference information of the user equipment. In addition, when the base station fails to obtain the positioning reference information, it may also send an NRPPa message of the message type Measurement Failure Indication to the positioning processing unit to feedback the acquisition failure information; based on the above failure indication, the positioning processing unit may send an NRPPa message of the message type Measurement Abort to the base station to instruct the base station to abort the sending process of the indication for obtaining the positioning reference information, thereby timely maintaining the user equipment or the base station. The positioning processing unit may use the positioning reference information, also known as UWB scanning data, to perform UWB positioning calculations to obtain positioning results.

[0064] In the above positioning method, the positioning processing unit obtains the positioning configuration information of the user equipment and sends the positioning configuration information to the base station. The base station sends a positioning instruction to the user equipment based on the positioning configuration information. The user equipment obtains positioning reference information based on the positioning instruction and sends it to the base station. The positioning processing unit determines the corresponding positioning result of the user equipment based on the positioning reference information sent by the base station. Compared with the traditional positioning method of independently constructing a positioning base station, this solution obtains the positioning configuration information of the user equipment through the positioning processing unit, and sends a positioning instruction to the user equipment based on the positioning configuration information through the base station. The user equipment only needs to obtain the positioning reference information, and the positioning processing unit performs positioning based on the positioning reference information. Therefore, there is no need to independently construct a positioning base station, which reduces the dependence on hardware resources during positioning and also reduces positioning costs.

[0065] Currently, building a UWB base station requires huge hardware resources. Based on this, this application uses the UWB scanning module as a peripheral of 5G TRP, without the need to support network addressing and routing functions, thereby reducing the dependence on hardware resources during positioning.

[0066] In one embodiment, obtaining the positioning configuration information of the user equipment includes: if periodic positioning information of the user equipment is obtained, determining the positioning configuration information according to the periodic positioning information.

[0067] In this embodiment, the positioning configuration information may include periodic positioning information. Periodic positioning information indicates that positioning reference information is acquired according to a preset period. If the positioning processing unit determines that the user equipment acquires information in a periodic positioning information manner, the positioning processing unit may determine the positioning configuration information based on the periodic positioning information. Consequently, after receiving the positioning configuration information, the base station may instruct the user equipment to acquire positioning reference information according to the preset period.

[0068] In one embodiment, obtaining the positioning configuration information of the user equipment includes: if the condition-triggered positioning information of the user equipment is obtained, then when it is detected that the user equipment meets the triggering condition corresponding to the condition-triggered positioning information, determining the positioning configuration information according to the condition-triggered positioning information.

[0069] In this embodiment, the above-mentioned positioning configuration information may also include conditional trigger positioning information. Conditional trigger positioning information indicates that positioning reference information is acquired only when a corresponding trigger condition is met. When the positioning processing unit determines that the user equipment's information acquisition method is conditional trigger positioning information, the positioning processing unit may detect whether the user equipment meets the trigger condition corresponding to the conditional trigger positioning information. If so, the positioning processing unit determines the above-mentioned positioning configuration information based on the conditional trigger positioning information. Thus, upon receiving the positioning configuration information, the base station may instruct the user equipment to scan and obtain positioning reference information only when it detects that the trigger condition corresponding to the conditional trigger positioning information is met.

[0070] Specifically, if the positioning configuration information includes periodic positioning information, the positioning processing unit may send an NRPPa message to the base station, adding the information type: UWB positioning, the positioning mode: periodic positioning, and carrying UWB positioning configuration parameters such as the positioning method. The gNB controls the connected TRP and sends a start periodic scan message to the user equipment's UWB module via the TRP peripheral interface. The user equipment uses the UWB module to provide the periodic scan UWB broadcast results to the TRP via the peripheral interface. The TRP sends the gNB, and the gNB sends a Measurement Report (scan result) message to the positioning processing unit via an NRPPa message.

[0071] If the positioning configuration information is determined based on conditional triggering of positioning information, the positioning method is conditional triggering. The positioning processing unit generates positioning configuration information when the triggering conditions of the conditional triggering positioning information are met. For example, the positioning processing unit only reports the positioning reference information when it scans the UWB_MAC (Ultra Wide Band_MAC, ultra-wideband communication media access control address) of a specific user device. The positioning processing unit generates positioning configuration information and sends it to the base station. The base station instructs the user device to obtain positioning reference information according to the triggering conditions of the conditional triggering positioning information. For example, the user device uses the UWB module to match the triggering conditions and positioning reference information, such as the above-mentioned UWB broadcast scanning results. If the triggering conditions are matched, the user device sends the scanning results, i.e., the above-mentioned positioning reference information, to the TRP of the base station, thereby achieving conditional triggering positioning.

[0072] Through the above-described embodiments, the positioning processing unit uses different positioning configurations based on the user equipment's positioning method to locate the user equipment, thereby improving the comprehensiveness of the positioning method. Furthermore, the positioning processing unit utilizes the existing 5G control plane NRPPa protocol to implement UWB scanning methods and the mobility management module of the 5G network to solve the problem of determining the terminal's location in wide-area UWB positioning, thereby improving the efficiency and reliability of positioning.

[0073] Currently, UWB positioning based on independent base stations has a high dependence on hardware resources for construction and also has the defect of low positioning accuracy. Based on this, this application combines UWB and 5G positioning data to perform integrated positioning of user devices, thereby improving positioning accuracy.

[0074] In one embodiment, obtaining the positioning configuration information of the user equipment further includes: generating the positioning configuration information according to the periodic positioning information or the condition-triggered positioning information, and the channel sounding reference signal positioning information.

[0075] In this embodiment, the positioning processing unit can also combine UWB with 5G positioning data such as UTDOA (Uplink Time Difference of Arrival), and perform multi-dimensional data calculations through a fusion positioning module to obtain a fusion positioning result. The positioning configuration information includes one or more of periodic positioning information and conditional trigger positioning information. For 5G positioning, this can be a positioning process based on SRS (Sounding Reference Signal) positioning information. That is, the positioning processing unit can perform fusion positioning based on the positioning reference information combined with positioning reference information corresponding to the channel sounding reference signal positioning information, thereby improving positioning accuracy. During the fusion positioning process, the positioning processing unit can generate positioning configuration information based on the periodic positioning information and the channel sounding reference signal positioning information, or based on the conditional trigger positioning information and the channel sounding reference signal positioning information. This allows positioning based on the periodic positioning information and the channel sounding reference signal positioning information, or based on the conditional trigger positioning information and the channel sounding reference signal positioning information.

[0076] In one embodiment, sending the above-mentioned positioning configuration information to the base station includes: sending the above-mentioned positioning configuration information to the above-mentioned base station; wherein, the above-mentioned positioning configuration information is used by the above-mentioned base station to send the first positioning instruction corresponding to the above-mentioned periodic positioning information or the above-mentioned condition-triggered positioning information to the above-mentioned user equipment, and to send the second positioning instruction corresponding to the above-mentioned channel sounding reference signal positioning information; wherein, the above-mentioned first positioning instruction and the above-mentioned second positioning instruction are used to instruct the above-mentioned user equipment to obtain the first positioning reference information and the second positioning reference information respectively and send them to the above-mentioned base station.

[0077] In this embodiment, for different UWB positioning modes, the positioning processing unit can instruct the base station to send different instructions, thereby realizing the acquisition of positioning reference information in different modes. Among them, the positioning processing unit can send positioning configuration information to the base station. The base station can send a first positioning instruction corresponding to periodic positioning information or conditional trigger positioning information to the user equipment based on the positioning configuration information, so that the user equipment can obtain the first positioning reference information based on the first positioning instruction, such as acquisition based on periodic scanning or acquisition based on conditional triggering. The base station can also send a second positioning instruction corresponding to channel sounding reference signal positioning information to the user equipment based on the positioning configuration information, so that the user equipment can obtain the second positioning reference information based on the channel sounding reference signal according to the second positioning instruction. After the user equipment obtains the first positioning reference information and the second positioning reference information respectively, it can send the first positioning reference information and the second positioning reference information to the base station. Thereby, the base station can return the positioning reference information to the positioning processing unit based on the first positioning reference information and the second positioning reference information.

[0078] In one embodiment, the positioning result corresponding to the above-mentioned user equipment is determined based on the above-mentioned positioning reference information sent by the above-mentioned base station, including: performing fusion positioning on the above-mentioned user equipment based on the above-mentioned first positioning reference information and the above-mentioned second positioning reference information sent by the above-mentioned base station to obtain the positioning result corresponding to the above-mentioned user equipment.

[0079] In this embodiment, after receiving the first positioning reference information and the second positioning reference information acquired by the user equipment, the base station may send the first positioning reference information and the second positioning reference information to the positioning processing unit. The positioning processing unit may then perform fusion positioning on the user equipment based on the first positioning reference information and the second positioning reference information sent by the base station, and obtain a positioning result corresponding to the user equipment.

[0080] Specifically, if Figure 4 As shown, Figure 4 This is a timing diagram of the fusion positioning steps in one embodiment. Through this process, the positioning processing unit (LMF) obtains the SRS signal measurement results of the TRP for 5G user devices and performs fusion positioning using UTDOA and UWB. For 5G+UWB user devices, UWB+5G fusion positioning can be performed, thereby integrating positioning data from multiple data types to improve accuracy and anti-interference capabilities.

[0081] The above-mentioned base stations include Serving gNB and Neighbour gNB, and the devices involved in the integrated positioning process include the above-mentioned positioning processing unit, base station and user equipment.

[0082] During the NRPPa TRP Configuration Information Exchange, the serving gNB and neighboring gNBs exchange positioning configuration information, such as the resources and frequency bands required for positioning. During the LPP (LTE Positioning Protocol) Capability Transfer, the user equipment transfers its positioning capabilities, such as LPP positioning protocol capabilities, to the positioning processing unit (LMF) via the serving gNB. The LMF then initiates an NRPPa Positioning Information Request to the serving gNB. The gNB determines UL SRS resources, i.e., the spectrum resources allocated by the serving gNB for uplink reference signal (SRS) for positioning measurements.

[0083] In the gNB Determines UL SRS Resources message, the serving gNB allocates uplink SRS resources to the user equipment (UE) for positioning measurements based on positioning requirements. In the UE SRS Configuration message, the serving gNB sends the allocated SRS configuration information to the UE. In the NRPPa Positioning Information Response message, the neighboring gNB and the serving gNB return positioning configuration information, including supported measurement configurations, to the positioning processing unit. In the NRPPa Positioning Activation Request / Response message, the serving gNB sends a positioning activation request to relevant base stations, including neighboring gNBs. Each gNB confirms its readiness for measurement and returns a response message. The positioning processing unit instructs the serving gNB and neighboring gNBs to configure resources and prepare for measurement via the NRPPa Positioning Activation Request message. In the Activate UE SRS Transmission message, the serving gNB notifies the UE to begin transmitting SRS signals using the allocated resources. If the user equipment is a 5G+UWB dual-mode device, the user equipment receives a UWB positioning configuration message and configures the UWB module according to the configuration parameters, such as the UTDOA or bidirectional TOF positioning process, thereby combining UWB positioning with the UTDOA or bidirectional TOF positioning process to achieve fusion positioning. The base station confirms the completion of the positioning configuration based on the NRPPa Positioning Activation Response and returns a response to the positioning processing unit.

[0084] In an NRPPa Measurement Request, the positioning processing unit sends an NRPPa message to the gNB. The message type is "Measurent Request," and the positioning type is "UWB." The positioning mode is "Periodic Scan" or "Conditional Triggered Scan." This allows the base station to instruct the user equipment to obtain the first and second positioning reference information. The user equipment uses UL SRS measurements (uplink sounding reference signal measurements) combined with the positioning configuration information to send the second positioning reference information corresponding to the uplink SRS signal. The base station then records the positioning parameters for the SRS signal.

[0085] The base station can also perform an NRPPa Measurement Response. The UWB module of the user equipment periodically scans the UWB broadcast results, such as the first positioning reference information mentioned above, and provides a TRP through the peripheral interface. The TRP is sent to the base station, and the base station sends a Measurement Response message to the positioning processing unit via an NRPPa message, which carries the UWB broadcast scan results. The positioning processing unit then performs fusion positioning based on the UWB broadcast scan results and the SRS signal to obtain the corresponding positioning result. The positioning processing unit can also send an NRPPa Positioning Deactivation message to the base station. Based on this information, the base station stops the relevant positioning measurement tasks and releases resources.

[0086] Through the above embodiment, the positioning processing unit determines the first positioning configuration information based on the periodic positioning information or the condition-triggered positioning information, and determines the second positioning configuration information based on the channel sounding reference signal, so that the base station instructs the user equipment to collect the first positioning reference information and the second positioning reference information based on the first positioning instruction and the second positioning instruction respectively. The positioning processing unit performs fusion positioning based on the first positioning reference information and the second positioning reference information, which can improve the positioning accuracy of the user equipment. In addition, for 5G+UWB dual-mode user equipment, the UWB module of the user equipment is activated according to the configuration parameters of 5G NRPPa to perform UTDOA or two-way TOF positioning process, without using the existing Bluetooth configuration process. Based on the control plane NRPPa protocol, the method of completing 5G UTDOA / AOA positioning and UWB positioning information collection and fusion positioning calculation in one process improves positioning efficiency.

[0087] In an exemplary embodiment, Figure 5 As shown, a positioning method is provided, which is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate the method, including the following steps S302 to S306. In which:

[0088] Step S302: Acquire the positioning configuration information of the user equipment sent by the positioning processing unit.

[0089] The base station may be a base station within the user equipment's range. The positioning configuration information may include various information, such as the user equipment's positioning method and UWB positioning configuration parameters. The UWB positioning configuration parameters indicate the specific method used by the user equipment to collect positioning parameter information. The positioning processing unit LMF may establish an NRPPa connection with the base station gNB where the user equipment is located via the AMF upon the user equipment's request. The positioning processing unit may send the positioning configuration information to the base station.

[0090] Step S304: Send a positioning instruction to the user equipment according to the positioning configuration information; the positioning instruction is used to instruct the user equipment to obtain positioning reference information and send it to the base station.

[0091] After receiving the positioning configuration information, the base station can send corresponding positioning instructions to the user equipment based on the positioning configuration information. For example, the base station determines the corresponding positioning mode and positioning method based on the positioning configuration information, and then sends a positioning instruction to the user equipment, instructing the user equipment on how to collect positioning reference information, such as periodic scanning or conditional trigger scanning, and how to collect positioning reference information, such as the collection steps and the information to be collected. After the user equipment obtains the positioning reference information based on the positioning instruction, it can send the positioning reference information to the base station.

[0092] Step S306: Send the positioning reference information to the positioning processing unit; the positioning reference information is used by the positioning processing unit to determine the positioning result corresponding to the user equipment.

[0093] The base station may return the positioning reference information to the positioning processing unit. The positioning processing unit may locate the user equipment based on the positioning reference information sent by the base station. For example, UWB positioning may be performed based on the positioning reference message. The positioning reference information may include various types of information.

[0094] In the above positioning method, the positioning processing unit obtains the positioning configuration information of the user equipment and sends the positioning configuration information to the base station. The base station sends a positioning instruction to the user equipment based on the positioning configuration information. The user equipment obtains positioning reference information based on the positioning instruction and sends it to the base station. The positioning processing unit determines the corresponding positioning result of the user equipment based on the positioning reference information sent by the base station. Compared with the traditional positioning method of independently constructing a positioning base station, this solution obtains the positioning configuration information of the user equipment through the positioning processing unit, and sends a positioning instruction to the user equipment based on the positioning configuration information through the base station. The user equipment only needs to obtain the positioning reference information, and the positioning processing unit performs positioning based on the positioning reference information. Therefore, there is no need to independently construct a positioning base station, which reduces the dependence on hardware resources during positioning and also reduces positioning costs.

[0095] In one embodiment, obtaining the positioning configuration information of the user equipment sent by the positioning processing unit includes: obtaining the positioning configuration information sent by the above-mentioned positioning processing unit; the above-mentioned positioning configuration information is obtained based on the above-mentioned periodic positioning information or the above-mentioned condition-triggered positioning information, and the above-mentioned channel sounding reference signal positioning information.

[0096] In this embodiment, the positioning processing unit can also combine UWB with 5G positioning data such as UTDOA (Uplink Time Difference of Arrival), and perform multi-dimensional data calculations through a fusion positioning module to obtain a fusion positioning result. For UWB positioning, the positioning configuration information includes one or more of periodic positioning information and conditional trigger positioning information. For 5G positioning, the positioning process can be based on SRS (Sounding Reference Signal) positioning information. Specifically, the positioning processing unit can perform fusion positioning based on the positioning reference information combined with positioning reference information corresponding to the SRS positioning information, thereby improving positioning accuracy. During the fusion positioning process, the positioning processing unit can generate positioning configuration information based on the periodic positioning information and the SRS positioning information, or based on the conditional trigger positioning information and the SRS positioning information. This enables positioning based on the periodic positioning information and the SRS positioning information, or based on the conditional trigger positioning information and the SRS positioning information. For different positioning modes, the base station can send different positioning instructions to the user equipment.

[0097] In one embodiment, sending a positioning instruction to the above-mentioned user equipment according to the above-mentioned positioning configuration information includes: sending a first positioning instruction corresponding to the above-mentioned periodic positioning information or the above-mentioned condition-triggered positioning information, and a second positioning instruction corresponding to the above-mentioned channel sounding reference signal positioning information to the above-mentioned user equipment according to the above-mentioned positioning configuration information; wherein the above-mentioned first positioning instruction and the above-mentioned second positioning instruction are used to instruct the above-mentioned user equipment to respectively obtain the first positioning reference information and the second positioning reference information and send them to the above-mentioned base station.

[0098] In this embodiment, for different UWB positioning modes, the positioning processing unit can instruct the base station to send different instructions, thereby achieving different modes of acquiring positioning reference information. The positioning processing unit can send positioning configuration information to the base station. Based on the positioning configuration information, the base station can send a first positioning instruction corresponding to periodic positioning information or conditionally triggered positioning information to the user equipment, so that the user equipment can acquire first positioning reference information based on the first positioning instruction, such as acquisition based on periodic scanning or acquisition based on conditional triggering. The base station can also send a second positioning instruction corresponding to channel sounding reference signal positioning information to the user equipment based on the positioning configuration information, so that the user equipment can acquire second positioning reference information based on the channel sounding reference signal based on the second positioning instruction. After the user equipment respectively acquires the first positioning reference information and the second positioning reference information, it can send the first positioning reference information and the second positioning reference information to the base station. The base station can then return positioning reference information to the positioning processing unit based on the first positioning reference information and the second positioning reference information. The positioning processing unit can perform a fusion positioning process based on the first positioning reference information and the second positioning reference information, thereby improving positioning accuracy.

[0099] In one embodiment, sending the above-mentioned positioning reference information to the above-mentioned positioning processing unit includes: sending the above-mentioned first positioning reference information and the above-mentioned second positioning reference information to the above-mentioned positioning processing unit; the above-mentioned first positioning reference information and the above-mentioned second positioning reference information are used by the above-mentioned positioning processing unit to perform fusion positioning on the above-mentioned user equipment to obtain the positioning result corresponding to the above-mentioned user equipment.

[0100] In this embodiment, after receiving the first positioning reference information and the second positioning reference information acquired by the user equipment, the base station may send the first positioning reference information and the second positioning reference information to the positioning processing unit. The positioning processing unit may then perform fusion positioning on the user equipment based on the first positioning reference information and the second positioning reference information sent by the base station, and obtain a positioning result corresponding to the user equipment.

[0101] Specifically, the base station combines the positioning processing unit and the user equipment to realize 5G+UWB integrated positioning based on the expansion of the existing architecture and interface of the 5G control plane. The base station gNB is set with an external electrical interface, such as USB or 232, etc. The user equipment sends the UWB scanning results to the TRP of the base station in real time through the UWB module, where the UWB scanning results can be positioning reference information, and the data packet of the positioning reference information sets the identification of the UWB user equipment, such as UWB_ID.

[0102] The gNB sends scanning results to the fusion positioning engine of the positioning processing unit via the enhanced NRPPa protocol. The base station detects UWB scanning results through the connected user device's UWB module and intelligently reports data based on the scan results. The base station also determines the UWB module managed by the user device based on the 5G network and activates the user device's UWB module for UWB measurement and positioning. The gNB sends the scanning data to the AMF, which then sends it to the positioning processing unit (LMF). The LMF / AMF combination implements mobility management. The positioning processing unit then fuses the UWB scanning data with 5G UTDOA measurement data to achieve high-precision fusion positioning. Furthermore, by leveraging existing 5G network interface protocols such as the NRPPa protocol, mobility management and efficient real-time scanning data collection are achieved. The user device's UWB scanning device does not need to support IP network protocols, thereby reducing positioning hardware resource dependence and eliminating the need for complex UWB system network routing configuration and management, reducing network costs and facilitating large-scale deployment.

[0103] Through the above embodiment, the positioning processing unit determines the first positioning configuration information based on the periodic positioning information or the condition-triggered positioning information, determines the second positioning configuration information based on the channel sounding reference signal, and instructs the user equipment to collect the first positioning reference information and the second positioning reference information based on the first positioning instruction and the second positioning instruction respectively through the base station. The positioning processing unit performs fused positioning based on the first positioning reference information and the second positioning reference information, which can improve the positioning accuracy of the user equipment.

[0104] In an exemplary embodiment, Figure 6 As shown, a positioning method is provided, which is applied to Figure 1 The user equipment in FIG. 1 is taken as an example to illustrate the method, including the following steps S402 to S404. In which:

[0105] Step S402: Acquire a positioning instruction sent by a base station; the positioning instruction is obtained by the base station according to the positioning configuration information of the user equipment.

[0106] The positioning configuration information may include a variety of information, such as the positioning method of the user equipment and UWB positioning configuration parameters. The UWB positioning configuration parameters indicate the specific method used by the user equipment to collect positioning parameter information. Based on the positioning configuration information, the base station may send corresponding positioning instructions to the user equipment. For UWB positioning, the positioning configuration information includes one or more of periodic positioning information and conditional trigger positioning information. For 5G positioning, it may be a positioning process based on SRS (Sounding Reference Signal) positioning information. That is, the positioning processing unit may perform fused positioning based on the positioning reference information combined with the positioning reference information corresponding to the channel sounding reference signal positioning information, thereby improving positioning accuracy.

[0107] Step S404: According to the positioning instruction, obtain positioning reference information and send it to the base station; the positioning reference information is used to instruct the base station to send the positioning reference information to the positioning processing unit; the positioning reference information is also used by the positioning processing unit to determine the positioning result corresponding to the user equipment.

[0108] After receiving the positioning configuration information, the base station can send corresponding positioning instructions to the user equipment based on the positioning configuration information. For example, the base station determines the corresponding positioning mode and positioning method based on the positioning configuration information, and then sends a positioning instruction to the user equipment, instructing the user equipment on how to collect positioning reference information, such as periodic scanning or conditional trigger scanning, and how to collect positioning reference information, such as the collection steps and what information needs to be collected. After the user equipment obtains the positioning reference information based on the positioning instruction, it can send the positioning reference information to the base station. The base station can then return the above positioning reference information to the positioning processing unit. The positioning processing unit can locate the user equipment based on the positioning reference information sent by the base station. For example, UWB positioning can be performed based on the positioning reference message. The above positioning reference information can include multiple types of information.

[0109] In one embodiment, according to the above-mentioned positioning instruction, obtaining positioning reference information includes: obtaining one or more of the media access control address, ultra-wideband communication signal strength, ultra-wideband communication signal timestamp, signal flight time and transmission power corresponding to the above-mentioned user equipment; obtaining positioning reference information according to one or more of the above-mentioned media access control address, the above-mentioned ultra-wideband communication signal strength, the above-mentioned ultra-wideband communication signal timestamp, the above-mentioned signal flight time and the above-mentioned transmission power.

[0110] In this embodiment, the positioning reference information collected by the user equipment includes, but is not limited to, one or more of the following: a media access control address corresponding to the user equipment, ultra-wideband communication signal strength, an ultra-wideband communication signal timestamp, a signal flight time, and a transmit power. The media access control address represents a MAC address, such as terminalMac (user equipment media access control address), which represents the MAC address of the UWB user equipment and can be expressed in the format of 00112233ABCD. The ultra-wideband communication signal strength can be RSSI (Received Signal Strength Indication), specifically the UWB signal strength received by the UWB indoor antenna from the UWB user equipment, and can be expressed in dBm. The ultra-wideband communication signal timestamp can be time, specifically the UWB signal timestamp received by the UWB indoor antenna from the UWB user equipment, and can be a string of digits. The signal flight time can be expressed as TOF (Time of Flight). The transmit power can be expressed as terminalPower (user equipment power), specifically the transmit power of the UWB user equipment, and can be expressed in dBm. In some embodiments, the positioning reference information may also include PDOA information (Phase Difference of Arrival information, positioning information based on phase difference of arrival), which means that the user equipment can receive phase difference information via multiple antennas; and AOA (Angle of Arrival) information. Based on the above information, the user equipment can obtain the corresponding positioning reference information, so that the positioning processing unit can locate the user equipment.

[0111] In the above positioning method, the positioning processing unit obtains the positioning configuration information of the user equipment and sends the positioning configuration information to the base station. The base station sends a positioning instruction to the user equipment based on the positioning configuration information. The user equipment obtains positioning reference information based on the positioning instruction and sends it to the base station. The positioning processing unit determines the corresponding positioning result of the user equipment based on the positioning reference information sent by the base station. Compared with the traditional positioning method of independently constructing a positioning base station, this solution obtains the positioning configuration information of the user equipment through the positioning processing unit, and sends a positioning instruction to the user equipment based on the positioning configuration information through the base station. The user equipment only needs to obtain the positioning reference information, and the positioning processing unit performs positioning based on the positioning reference information. Therefore, there is no need to independently construct a positioning base station, which reduces the dependence on hardware resources during positioning and also reduces positioning costs.
