Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, apparatus, and storage medium for positioning a terminal device. Background Art

[0002] Location Based Services (LBS) technology is a service technology that obtains terminal location information through wireless communication networks or other positioning systems, and then provides various location-related information to the terminal in combination with a geographic information system.

[0003] In the fifth-generation (5G) positioning network architecture, the Location Management Function (LMF) determines the positioning method used by the terminal device. Furthermore, the serving base station and the non-serving base station determine the positioning assistance data corresponding to the aforementioned positioning method and send the positioning assistance information to the LMF, enabling the LMF to determine the location information of the terminal device. The positioning assistance data includes the time-frequency resource configuration, period, and muting mechanism of the Positioning Reference Signal (PRS) / Sounding Reference Signal (SRS).

[0004] However, the above positioning method will cause a large overhead of system resources, resulting in a waste of resources. Summary of the Invention

[0005] The present application provides a terminal device positioning method, apparatus and storage medium, which can ensure the positioning accuracy and positioning delay of the terminal device, and can reduce the overhead of system resources and reduce resource waste.

[0006] In one aspect, the present application provides a method for positioning a terminal device, applied to a first network element, comprising:

[0007] Receive a first message from a terminal device, where the first message includes positioning service quality QoS information;

[0008] Sending a second message to the first network device, where the second message includes the positioning QoS information or initial positioning assistance data corresponding to the positioning QoS information;

[0009] receiving first target positioning assistance data sent by the first network device, and sending the first target positioning assistance data to the second network device, where the first target positioning assistance data is related to the positioning QoS information;

[0010] receiving a first positioning measurement value from the first network device and a second positioning measurement value from the second network device, where the first positioning measurement value is obtained by the first network device measuring the uplink positioning reference signal after receiving the uplink positioning reference signal according to the first target positioning assistance data, and the second positioning measurement value is obtained by the second network device measuring the uplink positioning reference signal after receiving the uplink positioning reference signal according to the first target positioning assistance data;

[0011] Determine the location information of the terminal device according to the first positioning measurement value and the second positioning measurement value.

[0012] In this solution, since the first network device can consider the positioning QoS information of each terminal device when allocating the first target positioning assistance data to the terminal device, the corresponding first target positioning assistance data can be allocated to each terminal device based on the positioning QoS information of each terminal device, instead of uniformly allocating positioning assistance data to all terminal devices. In this way, since the positioning QoS information of each terminal device is taken into consideration when allocating positioning assistance data to the terminal device, not only the positioning accuracy and positioning delay of the terminal device can be guaranteed, but also the overhead of system resources can be reduced, thereby reducing resource waste.

[0013] In a possible implementation manner, the second message includes initial positioning assistance data corresponding to the positioning QoS information;

[0014] Before sending the second message to the first network device, the method further includes:

[0015] Determining the value of the configuration parameter corresponding to the positioning QoS information according to the correspondence between the pre-stored positioning QoS information, the configuration parameter of the positioning reference signal, and the threshold value corresponding to the configuration parameter;

[0016] The value of the configuration parameter is determined as the initial positioning assistance data.

[0017] In this solution, the first network element can determine the value of the configuration parameter corresponding to the positioning QoS information based on the correspondence between the pre-stored positioning QoS information, the configuration parameters of the positioning reference signal and the threshold value corresponding to the configuration parameter, and determine the value as the initial positioning assistance data. In this way, the positioning assistance data and the positioning QoS information of the terminal device can be associated, avoiding the phenomenon of uniformly allocating positioning assistance data to all terminal devices in the existing technology. Instead, the positioning QoS information of each terminal device is taken into consideration, and the corresponding positioning assistance data is allocated to the terminal device, thereby not only ensuring the positioning accuracy and positioning delay of the terminal device, but also reducing the overhead of system resources and reducing resource waste.

[0018] In a possible implementation, the first message further includes capability information of the terminal device;

[0019] The method further comprises:

[0020] Update the threshold value corresponding to the configuration parameter according to the capability information of the terminal device.

[0021] In this solution, since the first network element can update the threshold value corresponding to the configuration parameter based on the capability information of the terminal device, it can avoid the phenomenon that all terminal devices use the same threshold value. This not only improves the flexibility of selecting the configuration parameter threshold value, but also determines different threshold values for each terminal device, thereby improving the accuracy of positioning assistance data.

[0022] In a possible implementation manner, the second message further includes positioning QoS information, configuration parameters of a positioning reference signal, and a correspondence between threshold values corresponding to the configuration parameters.

[0023] In this solution, since the first network element can pre-send the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal and the threshold values corresponding to the configuration parameters to the first network device, the correspondence will be stored locally on the first network device. After receiving the positioning QoS information sent by the first network element, the first network device can directly determine the initial positioning assistance data based on the correspondence, without the need for the first network element to send the correspondence to the first network device every time the initial positioning assistance data is determined, thereby improving the efficiency of determining the initial positioning assistance data.

[0024] In a possible implementation manner, the second message also includes a threshold value corresponding to the updated configuration parameter.

[0025] In this solution, after the first network element updates the threshold value corresponding to the configuration parameter according to the capability information of the terminal device, the updated threshold value is sent to the first network device. This not only improves the flexibility of selecting the configuration parameter threshold value, but also allows different threshold values to be determined for each terminal device, thereby improving the accuracy of the determined positioning assistance data.

[0026] In a possible implementation, the number of the terminal devices is at least two;

[0027] The method further comprises:

[0028] Obtaining a priority of each terminal device among at least two terminal devices;

[0029] The determining, based on a correspondence between pre-stored positioning QoS information, configuration parameters of positioning reference signals, and threshold values corresponding to the configuration parameters, a value of the configuration parameter corresponding to the positioning QoS information includes:

[0030] Determining the positioning QoS information of the terminal device with the highest or lowest priority among the at least two terminal devices as the target positioning QoS information;

[0031] According to the correspondence between pre-stored positioning QoS information, configuration parameters of positioning reference signals and threshold values corresponding to the configuration parameters, the value of the configuration parameter corresponding to the target positioning QoS information is determined.

[0032] In this solution, the first network element can determine the final target positioning QoS information according to the priorities corresponding to at least two terminal devices, thereby determining the corresponding initial positioning assistance data, thereby improving the accuracy of the initial positioning assistance data.

[0033] On the other hand, the present application provides a terminal device positioning method, applied to a first network element, comprising:

[0034] Receive a first message from a terminal device, where the first message includes positioning service quality QoS information;

[0035] Sending a second message to the first network device and the second network device respectively, where the second message includes the positioning QoS information or initial positioning assistance data corresponding to the positioning QoS information;

[0037] Sending the first target positioning assistance data and the second target positioning assistance data to the terminal device;

[0038] receiving a first positioning measurement value and a second positioning measurement value sent by the terminal device, where the first positioning measurement value is obtained by the terminal device receiving a first downlink positioning reference signal sent by the first network device according to the first target positioning assistance data and measuring the first downlink positioning reference signal, and the second positioning measurement value is obtained by the terminal device receiving a second downlink positioning reference signal sent by the second network device according to the second target positioning assistance data and measuring the second downlink positioning reference signal;

[0039] Determine the location information of the terminal device according to the first positioning measurement value and the second positioning measurement value.

[0040] In this solution, since the first network device can consider the positioning QoS information of each terminal device when allocating the first target positioning assistance data to the terminal device, the corresponding first target positioning assistance data can be allocated to each terminal device based on the positioning QoS information of each terminal device, instead of uniformly allocating positioning assistance data to all terminal devices.

This not only improves the flexibility of selecting the configuration parameter threshold value, but also determines different threshold values for each terminal device, thereby improving the accuracy of positioning assistance data.

[0050] In a possible implementation manner, the second message further includes positioning QoS information, configuration parameters of a positioning reference signal, and a correspondence between threshold values corresponding to the configuration parameters.

[0051] In this solution, since the first network element can pre-send the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal and the threshold values corresponding to the configuration parameters to the first network device, the correspondence will be stored locally on the first network device. After receiving the positioning QoS information sent by the first network element, the first network device can directly determine the initial positioning assistance data based on the correspondence, without the need for the first network element to send the correspondence to the first network device every time the initial positioning assistance data is determined, thereby improving the efficiency of determining the initial positioning assistance data.

[0059] According to the correspondence between pre-stored positioning QoS information, configuration parameters of positioning reference signals and threshold values corresponding to the configuration parameters, the value of the configuration parameter corresponding to the target positioning QoS information is determined.

[0060] In this solution, the first network element can determine the final target positioning QoS information according to the priorities corresponding to at least two terminal devices, thereby determining the corresponding initial positioning assistance data, thereby improving the accuracy of the initial positioning assistance data.

[0252] The present application provides a method, apparatus, and storage medium for positioning a terminal device.

This allows the first network element to obtain positioning measurement values corresponding to the first target positioning assistance data to determine the location information of the terminal device. Because the first network device can consider the positioning QoS information of each terminal device when allocating the first target positioning assistance data to the terminal device, the first target positioning assistance data corresponding to the positioning QoS information of each terminal device is allocated to each terminal device, rather than uniformly allocating the positioning assistance data to all terminal devices. Thus, since the positioning assistance data is allocated to each terminal device based on its positioning QoS information, not only can the positioning accuracy and positioning latency of the terminal device be guaranteed, but system resource overhead and resource waste can also be reduced.

[0268] In this application, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0269] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0270] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0271] The terminal device positioning method, device and storage medium provided in the embodiments of the present application are used in any application scenario that requires determining the location of the terminal device, such as navigation, ranging, locating the calling user based on an emergency call, or locating other authorized users based on user requests, etc.

[0272] The technical solution provided in the embodiments of the present application can be applicable to a variety of systems, especially 5G systems. For example, applicable systems may be global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G new radio (NR) systems, etc. These various systems include terminal devices and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0273] Figure 1 This is a schematic diagram of the 5G communication system structure applicable to the embodiment of the present application, such as Figure 1As shown, the 5G communication system consists of a 5G core network (5G Core, 5GC) network element 101 and a radio access network (Next Generation Radio Access Network, NG-RAN) network element 102, and the 5GC network element 101 and the NG-RAN network element 102 are connected through the NG port.

[0274] Among them, the network elements that make up 5GC 101 include the Access and Mobility Management Function (AMF) for supporting control plane functions such as access and mobility management, the Core Network Location Management Function (CN LMF) for providing positioning services, and the User Plane Function (UPF) for supporting user plane functions (not shown in the figure).

[0275] The network elements that make up the NG-RAN include RAN nodes (as shown in the figure, 102a to 102d). RAN nodes include network equipment, such as gNBs that provide wireless network user plane and control plane protocols and functions for 5G networks, or ng-eNBs that provide wireless network user plane and control plane protocols and functions for 4G network users. On the access network side, gNBs and ng-eNBs, gNBs and gNBs, and gNBs are connected through Xn ports, that is, the RAN nodes in the access network are connected through Xn ports. It should be noted that in the following description, the AMF entity is referred to as AMF, and the LMF entity is referred to as LMF.

[0276] Among them, the RAN node includes the service base station of the terminal device and the neighboring station of the terminal device. For example, if the terminal device is in the cell covered by gNB 102a, gNB 102a is the service base station of the terminal device, and gNB 102b is the neighboring station of the terminal device.

[0277] It should be noted that the above architecture is described using the 5G system architecture as an example. The embodiments of the present application may also be applicable to 5G evolution systems, or to other communication systems (such as 4G communication systems), or to system architectures for hybrid networking of 5G systems and other communication systems (such as 4G systems), which are not listed here one by one. For example, in a 4G communication system or a system in which a 4G communication system and a 5G communication system are hybrid networked, mobility management may be implemented by a Mobility Management Entity (MME).

[0278] Based on the above system structure, the CN LMF in the core network provides positioning services for terminal devices through the RAN node in collaboration with core network elements such as AMF or MME.

[0279] Figure 2 This is a schematic diagram of the positioning service network structure in the 5G network to which the embodiment of the present application is applicable. The figure exemplarily lists some network elements related to the embodiment of the present application. Figure 2 As shown, the LMF includes a core network LMF (such as LMF 203 in the figure) and a local LMF (LLMF) located on the access network side. The local LMF is associated with a RAN node. For example, a local LMF can correspond to one or more RAN nodes. The local LMF can be co-located with a RAN node, so that the local LMF is associated with the co-located RAN node (such as local LMF (LLMF) 206 co-located with RAN node 204 in the figure).

[0280] Based on the above system architecture, the terminal device's location service process may include: LCS entity 201 initiating a location service request to AMF 202; AMF 202 selecting an LMF to provide location services for terminal device 205 based on the network configuration and information related to terminal device 205. If AMF 202 selects LMF 203 to provide location services for terminal device 205, it initiates a location service request to LMF 203. If AMF selects LLMF 206 co-located with the RAN node (i.e., serving RAN node) 204 where terminal device 205 resides to provide location services for terminal device 205, it initiates a location service request to LLMF 206 co-located with RAN node 204. LMF 203 or LLMF 206 obtains the location information of terminal device 205 by interacting with AMF 202, RAN node 204, and terminal device 205, and sends a location service response message to LCS entity 201 via AMF 202. This completes the determination of the terminal device's location information.

[0281] The terminal device involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. 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 can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present application.

[0282] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station 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 may be named otherwise. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting 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 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 (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., and 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 geographically separated.

[0283] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be either Single User MIMO (SU-MIMO) or Multi User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or Massive-MIMO. It can also use diversity transmission, precoding, or beamforming.

[0284] The LMF involved in the embodiment of the present application can be used to realize the location estimation of the terminal device. The LMF can be deployed inside the core network, that is, the LMF is also a core network element. The LMF can communicate with the access network device, such as the access node NGRAN, through the AMF. For the convenience of description, in the embodiment of the present application, the LMF sending information to the access network device through the AMF is referred to as the LMF sending information to the access network device. In other words, the LMF sending a message to the access network device in the embodiment of the present application can be understood as the LMF first sending the information to the AMF, and the AMF then forwarding the information to the access network device.

[0285] In addition, the LMF can also communicate with the terminal device. For example, the LMF can communicate with the terminal device via the LTE positioning protocol (LPP).

[0286] Currently, in the 5G new radio (NR) protocol, when determining the location information of a terminal device, the positioning method used to locate the terminal device is usually determined by the LMF. However, the positioning reference signal, positioning assistance data, and measurement reporting mechanism involved in this positioning method are allocated to the terminal device by the serving base station. When the serving base station allocates positioning reference signals and corresponding positioning assistance data to the terminal device, in order to ensure the positioning accuracy and latency of all terminal devices, it will allocate positioning assistance data to all terminal devices based on the relevant parameters of the terminal device with the worst communication performance, such as allocating positioning reference signal (PRS) resources / sounding reference signal (SRS) resources. This will increase the overhead of system resources and cause resource waste.

[0287] In view of the above problems, a positioning method for a terminal device is proposed in an embodiment of the present application. In this method, a correspondence between positioning service quality (QoS) information, configuration parameters of the positioning reference signal and threshold values corresponding to the configuration parameters can be pre-established through protocol pre-definition or pre-configuration. The first network element or the serving base station will determine the initial positioning assistance data corresponding to the positioning QoS information based on the correspondence, so that the serving base station and / or the adjacent base station can consider the positioning QoS information of each terminal device when allocating target positioning assistance data to the terminal device, and allocate corresponding target positioning assistance data to each terminal device based on the positioning QoS information of each terminal device, instead of uniformly allocating positioning assistance data to all terminal devices. In this way, since the positioning QoS information of each terminal device is taken into consideration to allocate positioning assistance data to the terminal device, not only the positioning accuracy and positioning delay of the terminal device can be guaranteed, but also the overhead of system resources can be reduced, and the waste of resources can be reduced.

[0288] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0289] Below, the technical solutions of the present application will be described respectively for the uplink positioning method, the downlink positioning method and the uplink+downlink positioning method.

[0290] Figure 3 This is a signaling flow chart of a positioning method for a terminal device provided in an embodiment of the present application. In this embodiment, the scheme of LMF using an uplink positioning method to determine the location information of the terminal device is described in detail. Figure 3 As shown, the method includes:

[0291] Step 301: A first network element receives a first message from a terminal device, where the first message includes positioning QoS information.

[0292] In this step, the first network element is Figure 2 The LMF in the LMF may be LMF 203 or LLMF 206. The first message sent by the terminal device to the first network element carries positioning QoS information. The positioning QoS information includes at least one of the following information: positioning accuracy, positioning latency, application scenario of the terminal device, such as application in high-speed scenarios or low-speed scenarios, or priority of the terminal device.

[0293] Step 302: The first network element sends a second message to the first network device, where the second message includes positioning QoS information or initial positioning assistance data corresponding to the positioning QoS information.

[0294] Wherein, the first network device includes a service base station of the terminal device. Exemplarily, when the transmission reception points (TRP) participating in sending or receiving on-demand PRS / SRS all belong to the same service base station, the service base station determines the time-frequency resource configuration parameters of the on-demand PRS / SRS, that is, determines the target positioning assistance data. When the TRP participating in sending or receiving on-demand PRS / SRS belongs to the service base station and the adjacent base station, the service base station and the adjacent base station respectively determine their respective time-frequency resource configuration parameters of the on-demand PRS / SRS, that is, the service base station and the adjacent base station respectively determine their respective corresponding target positioning assistance data. In this application, the case where the TRP participating in sending or receiving on-demand PRS / SRS belongs to the service base station and the adjacent base station is explained.

[0295] After receiving the positioning QoS information sent by the terminal device, the first network element can determine the initial positioning assistance data based on the positioning QoS information and send the initial positioning assistance data to the first network device, or it can directly send the received positioning QoS information to the first network device so that the first network device determines the positioning assistance data based on the positioning QoS information.

[0296] For the case where the first network element determines the initial positioning assistance data, that is, the second message sent by the first network element includes the initial positioning assistance data corresponding to the positioning QoS information, the first network element pre-stores the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters, wherein the configuration parameters of the positioning reference signal include the frequency domain bandwidth X of the PRS / SRS, the number of orthogonal frequency division multiplexing (OFDM) symbols Y of the PRS / SRS in the time domain, the PRS beam width Z, the muting mechanism start flag, the reference signal period T1, and the measurement reporting period T2, etc. In addition, each configuration parameter corresponds to its own threshold value, such as the threshold value corresponding to the frequency domain bandwidth X of the PRS / SRS is X_th, the threshold value corresponding to the number of OFDM symbols Y is Y_th, the threshold value corresponding to the PRS beamwidth Z is Z_th, the threshold value of the reference signal period T1 is T1_th, and the threshold value of the measurement reporting period T2 is T2_th. The specific values of the above threshold values are related to the capabilities supported by the terminal device, that is, the specific values of the above threshold values are different depending on the capabilities of the terminal device. It can be understood that the capabilities supported by the terminal device include the capabilities possessed by the terminal device, or the terminal device's ability to process data or information, or the data processing methods or algorithms supported by the terminal device.

[0297] Illustratively, the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters may be determined in advance through simulation or based on existing test results.

[0298] For example, Table 1 shows a possible correspondence between positioning QoS information, configuration parameters of positioning reference signals, and threshold values corresponding to the configuration parameters:

[0299] Table 1

[0300]

[0301]

[0302] Among them, the high positioning accuracy in Table 1 can be understood as the positioning accuracy being greater than the first preset value, the low positioning accuracy can be understood as the positioning accuracy being no greater than the first preset value, the high positioning delay can be understood as the positioning delay being greater than the second preset value, the low positioning delay can be understood as the positioning delay being no greater than the second preset value, the high-speed scenario can be understood as the moving speed of the terminal device being greater than the third preset value, such as the high-speed rail, subway or light rail scenario, and the low-speed scenario can be understood as the moving speed of the terminal device being no greater than the third preset value, such as the running scenario.

[0303] It should be noted that, in addition to being stored in the table format shown in Table 1, the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters can also be defined explicitly using a protocol or defined using a function, for example, by the following formula (1):

[0304] Configuration parameters of the positioning reference signal Y_set = f(positioning QoS information X1_set, terminal device capability information X2); (1)

[0305] Among them, the capability information X2 of the terminal device is used to determine different threshold values. Therefore, if the first message sent by the terminal device also includes the capability information of the terminal device, the first network element will update or adjust the threshold value corresponding to the configuration parameter based on the received capability information. For example, if the terminal device has a strong ability to process data, the threshold value corresponding to the configuration parameter can be updated to a larger value; if the terminal device has a weak ability to process data, the threshold value corresponding to the configuration parameter can be updated to a smaller value, etc. In addition, the threshold value corresponding to the capability information of the terminal device included in the first message can also be updated based on the correspondence between the pre-set capability information of the terminal device and the threshold value corresponding to the configuration parameter.

[0306] Exemplarily, the terminal device may carry the capability information of the terminal device in a first message and send it to the first network element, or may carry it in other messages and send it to the first network element, and this embodiment of the present application does not limit this.

[0307] Since the first network element can update the threshold value corresponding to the configuration parameter based on the capability information of the terminal device, this can avoid the phenomenon that all terminal devices use the same threshold value. This not only improves the flexibility of selecting the configuration parameter threshold value, but also allows different threshold values to be determined for each terminal device, thereby improving the accuracy of the positioning assistance data.

[0308] Furthermore, in addition to storing the corresponding relationship in Table 1 and / or the corresponding relationship in formula (1), the first network element also stores the corresponding relationship between positioning QoS information and positioning methods, wherein the positioning method includes an uplink positioning method, a downlink positioning method, and an uplink and downlink positioning method, such as a multi-station round-trip time (Multi Round-Trip Time, Multi-RTT).

[0309] After receiving the positioning QoS information sent by the terminal device, the first network element will determine the positioning method to be used based on the pre-stored correspondence between the positioning QoS information and the positioning method. In addition, it is also necessary to determine the configuration parameters of the positioning reference signal based on the positioning method. For example, if the positioning method is an uplink positioning method, the configuration parameters of the positioning reference signal will include the frequency domain bandwidth of the PRS, the number of OFDM symbols of the PRS, the PRS beamwidth, the muting mechanism enable flag, the reference signal period T1, and the measurement reporting period T2. If the positioning method is a downlink positioning method, the configuration parameters of the positioning reference signal will include the frequency domain bandwidth of SRS, the number of OFDM symbols of SRS, the muting mechanism activation flag, the reference signal period T1 and the measurement reporting period T2, etc. If the positioning method is an uplink and downlink joint (i.e., uplink + downlink) positioning method, the configuration parameters of the positioning reference signal will include the frequency domain bandwidth of PRS, the frequency domain bandwidth of SRS, the number of OFDM symbols of PRS, the number of OFDM symbols of SRS, the PRS beam width, the muting mechanism activation flag, the reference signal period T1 and the measurement reporting period T2, etc.

[0310] In this embodiment, the uplink positioning method is used for illustration. After determining the configuration parameters of the positioning reference signal, the first network element determines the value of the configuration parameter corresponding to the positioning QoS information based on the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold value corresponding to the configuration parameter as shown in Table 1 or Formula (1), and determines the value as the initial positioning assistance data.

[0311] For example, when the positioning QoS information is high positioning accuracy and low positioning delay, and the terminal device is used in a high-speed scenario, the first network element determines that the positioning method is the uplink positioning method based on the positioning QoS information. According to the corresponding relationship in Table 1, the initial positioning assistance data determined by the first network element is: the frequency domain bandwidth of PRS is greater than the threshold value X_th, the number of time domain OFDM symbols of PRS is less than the threshold value Y_th, the beam width of PRS is less than the threshold value Z_th, the muting mechanism activation flag is YES, the reference signal period T1 is less than the threshold value T1_th, and the measurement reporting period T2 is less than the threshold value T2_th.

[0312] In this embodiment, the first network element can determine the value of the configuration parameter corresponding to the positioning QoS information based on the correspondence between the pre-stored positioning QoS information, the configuration parameters of the positioning reference signal and the threshold value corresponding to the configuration parameter, and determine the value as the initial positioning assistance data. In this way, the positioning assistance data and the positioning QoS information of the terminal device can be associated, avoiding the phenomenon of uniformly allocating positioning assistance data to all terminal devices in the existing technology. Instead, the positioning QoS information of each terminal device is taken into consideration, and the corresponding positioning assistance data is allocated to the terminal device, thereby not only ensuring the positioning accuracy and positioning delay of the terminal device, but also reducing the overhead of system resources and reducing resource waste.

[0313] Furthermore, if the first network element receives a first message sent by at least two terminal devices within a cell managed by the same base station, the first network element can first obtain the priority of each terminal device. In this way, when determining the value of the configuration parameter corresponding to the positioning QoS information based on the correspondence between the pre-stored positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters, the positioning QoS information of the terminal device with the highest or lowest priority among the at least two terminal devices will be determined as the target positioning QoS information, and then the value of the configuration parameter corresponding to the target positioning QoS information will be determined based on the correspondence between the pre-stored positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters.

[0314] Specifically, the priority of the terminal device may be carried in the first message sent to the first network element, or may be determined by the first network element based on the positioning QoS information sent by each terminal device.

[0315] If the priorities corresponding to at least two terminal devices are not all the same, the first network element may determine the positioning QoS information of the terminal device with the highest or lowest priority as the target positioning QoS information based on the priorities of the terminal devices, wherein the determined target positioning QoS information will be the positioning QoS information shared by all terminal devices. The first network element will determine the value of the configuration parameter corresponding to the target positioning QoS information based on the correspondence between the positioning QoS information, the configuration parameter of the positioning reference signal, and the threshold value corresponding to the configuration parameter, and determine the value as the initial positioning assistance data.

[0316] After determining the initial positioning assistance data, the first network element sends the initial positioning assistance data to the first network device.

[0317] It is understandable that the first network element may also send the determined priority of each terminal device to the first network device, and the first network device may determine the target positioning QoS information according to the priority.

[0318] In this embodiment, the first network element may determine the final target positioning QoS information according to the priorities corresponding to at least two terminal devices, thereby determining the corresponding initial positioning assistance data, thereby improving the accuracy of the initial positioning assistance data.

[0319] In addition, the first network element may also directly send the received positioning QoS information to the first network device, and the first network device determines the positioning assistance data. The case where the first network device determines the positioning assistance data will be described in detail below.

[0320] Step 303: The first network device determines first target positioning assistance data according to the positioning QoS information or the initial positioning assistance data.

[0321] In this step, if the second message includes the positioning QoS information of the terminal device, the first network device can determine the value of the configuration parameter corresponding to the positioning QoS information based on the correspondence between the pre-stored QoS information, the configuration parameters of the positioning reference signal and the threshold value corresponding to the configuration parameter when determining the first target positioning assistance data, and determine the first target positioning assistance data based on the value of the configuration parameter.

[0322] Specifically, in one possible implementation, the second message sent by the first network element to the first network device also includes the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters. In this way, the first network device will store the correspondence locally.

[0323] In this manner, since the first network element can pre-send the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal and the threshold values corresponding to the configuration parameters to the first network device, the correspondence will be stored locally on the first network device. After receiving the positioning QoS information sent by the first network element, the first network device can directly determine the initial positioning assistance data based on the correspondence, without the need for the first network element to send the correspondence to the first network device every time the initial positioning assistance data is determined, thereby improving the efficiency of determining the initial positioning assistance data.

[0324] In another possible implementation, the first network element and the first network device may store a correspondence between the positioning QoS information and the configuration parameters of the positioning reference signal. For the threshold value corresponding to the configuration parameter, a preset value or a fixed value may be used.

[0325] In another possible implementation, a first message received by a first network element from a terminal device includes capability information of the terminal device. The first network element may determine, based on the capability information of the terminal device, a threshold value for a configuration parameter of a positioning reference signal corresponding to the positioning QoS information, and include the threshold value in a second message. In this approach, the network device pre-stores a correspondence between positioning QoS information and configuration parameters of positioning reference signals. After receiving the first message, the first network element may determine, based on the correspondence between the capability information of the terminal device and the threshold value, and the capability information of the terminal device included in the first message, the threshold value corresponding to each configuration parameter of the positioning reference signal, and transmit the threshold value to the network device in a second message. After receiving the threshold value corresponding to each configuration parameter of the positioning reference signal, the network device determines initial positioning assistance data based on the pre-stored correspondence between the positioning QoS information and the configuration parameters of the positioning reference signal.

[0326] In addition, the first network element may also update the threshold value corresponding to the configuration parameter according to the capability information of the terminal device. After the update is completed, the updated threshold value may be carried in the second message and sent to the first network device.

[0327] In this method, the first network element can determine the threshold value of the configuration parameter of the positioning reference signal based on the capability information of the terminal device, which not only improves the flexibility of selecting the configuration parameter threshold value, but also can determine different threshold values for each terminal device, thereby improving the accuracy of the determined positioning assistance data.

[0328] Furthermore, the corresponding relationship between the positioning QoS information, the configuration parameters of the positioning reference signal and the threshold values corresponding to the configuration parameters is similar to the corresponding relationship described in Table 1 or formula (1), and will not be repeated here.

[0329] After obtaining the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters, the first network device determines the value of the configuration parameter corresponding to the positioning QoS information. For example, the first network device may directly determine the value of the determined configuration parameter as the first target positioning assistance data, or may adjust the value of the configuration parameter based on resource allocation conditions to obtain the first target positioning assistance data.

[0330] In this method, the first network device can determine the value of the configuration parameter corresponding to the positioning QoS information based on the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal and the threshold value corresponding to the configuration parameter, and thus determine the first target positioning assistance data based on the value. In this way, the corresponding first target positioning assistance data can be allocated to each terminal device based on the positioning QoS information of each terminal device, instead of uniformly allocating positioning assistance data to all terminal devices. In this way, since the positioning QoS information of each terminal device is taken into consideration to allocate positioning assistance data to the terminal device, not only the positioning accuracy and positioning delay of the terminal device can be guaranteed, but also the overhead of system resources can be reduced and the waste of resources can be reduced.

[0331] If the second message includes initial positioning assistance data corresponding to the positioning QoS information, the first network device can directly determine the initial positioning assistance data determined by the first network element as the first target positioning assistance data, thereby improving the efficiency of determining the first target positioning assistance data. In addition, the first network device can also adjust the initial positioning assistance data based on resource allocation to obtain the first target positioning assistance data, thereby improving resource utilization.

[0332] Exemplarily, if the first network element receives a first message sent by at least two terminal devices, the first network element will determine the priority of each terminal device and send the priority of each terminal device to the first network device. The first network device can determine the positioning QoS information of the terminal device with the highest or lowest priority as the target positioning QoS information based on the priority of each terminal device, and determine the value of the configuration parameter corresponding to the target positioning QoS information in combination with the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal and the threshold values corresponding to the configuration parameters, thereby determining the initial positioning assistance data.

[0333] Step 304: The first network device sends first target positioning assistance data to the first network element and the terminal device respectively, where the first target positioning assistance data is related to the positioning QoS information.

[0334] In this step, after determining the first target positioning assistance data, the first network device sends the first target positioning assistance data to the first network element. Because the first target positioning assistance data is related to the positioning QoS information, different target positioning assistance information can be allocated to different terminal devices based on the positioning QoS information of the terminal device. This not only ensures the positioning accuracy and positioning latency of the terminal device, but also reduces system resource overhead and reduces resource waste.

[0335] Furthermore, the first network device will also send the first target positioning assistance data and positioning method to the terminal device.

[0336] Step 305: The first network element sends first target positioning assistance data to the second network device.

[0337] In this step, the second network device is a neighboring base station of the terminal device. After receiving the first target positioning assistance data sent by the first network device, the first network element will send the first target positioning assistance data to the second network device.

[0338] Step 306: The first network element receives a first positioning measurement value from the first network device and a second positioning measurement value from the second network device.

[0339] Among them, the first positioning measurement value is obtained after the first network device receives the uplink positioning reference signal SRS-Pos according to the first target positioning assistance data and measures the uplink positioning reference signal SRS-Pos, and the second positioning measurement value is obtained after the second network device receives the uplink positioning reference signal SRS-Pos according to the first target positioning assistance data and measures the uplink positioning reference signal SRS-Pos.

[0340] In this step, if the positioning method determined by the first network element is the uplink positioning method, after receiving the first target positioning assistance data sent by the first network device, the terminal device will send an uplink positioning reference signal SRS-Pos to the first network device and the second network device respectively according to the first target positioning assistance data.

[0341] The first network device will obtain the time-frequency resource configuration parameters of the uplink positioning reference signal (SRS-Pos) based on the first target positioning assistance data determined by itself, thereby receiving the uplink positioning reference signal (SRS-Pos) sent by the terminal device based on the time-frequency resource configuration parameters, and measuring the received uplink positioning reference signal (SRS-Pos) to obtain a first positioning measurement value. Furthermore, the first network device can send the determined first positioning measurement value to the first network element.

[0342] The second network device will obtain the time-frequency resource configuration parameters of the uplink positioning reference signal SRS-Pos based on the first target positioning assistance data sent by the first network element, thereby receiving the uplink positioning reference signal SRS-Pos sent by the terminal device based on the time-frequency resource configuration parameters, and measuring the received uplink positioning reference signal SRS-Pos to obtain a second positioning measurement value. Furthermore, the first network device can send the determined first positioning measurement value to the first network element.

[0343] Step 307: The first network element determines the location information of the terminal device based on the first positioning measurement value and the second positioning measurement value.

[0344] In this step, after the first network element obtains the first positioning measurement value and the second positioning measurement value, it will combine the location information of the first network device and the second network device to calculate the location information of the terminal device.

[0345] In a terminal device positioning method provided by an embodiment of the present application, a first message received by a first network element from a terminal device includes positioning QoS information. The first network element can determine initial positioning assistance data based on the positioning QoS information and send the initial positioning assistance data to the first network device, or the first network element can directly send the positioning QoS information to the first network device, so that the first network device determines first target positioning assistance data based on the initial positioning assistance data or the positioning QoS information, thereby enabling the first network element to obtain positioning measurement values corresponding to the first target positioning assistance data to determine the location information of the terminal device. Because the first network device can consider the positioning QoS information of each terminal device when allocating the first target positioning assistance data to the terminal device, the first target positioning assistance data corresponding to the positioning QoS information of each terminal device is allocated to each terminal device separately, rather than uniformly allocating positioning assistance data to all terminal devices. In this way, since the positioning QoS information of each terminal device is considered when allocating positioning assistance data to the terminal device, not only can the positioning accuracy and positioning latency of the terminal device be guaranteed, but the overhead of system resources can also be reduced, thereby reducing resource waste.

[0346] Figure 4 This is a signaling flow chart of a positioning method for a terminal device provided in another embodiment of the present application. In this embodiment, the scheme of LMF using a downlink positioning method to determine the location information of the terminal device is described in detail. Figure 4 As shown, the method includes:

[0347] Step 401: A first network element receives a first message from a terminal device, where the first message includes positioning QoS information.

[0348] Step 401 is similar to step 301. For details, please refer to the description of step 301 and will not be repeated here.

[0349] Step 402: The first network element sends a second message to the first network device and the second network device respectively. The second message includes positioning QoS information or initial positioning assistance data corresponding to the positioning QoS information.

[0350] Among them, the first network device includes a service base station of the terminal device, and the second network device includes an adjacent base station of the terminal device. Exemplarily, when the transmission reception points (TRP) participating in sending or receiving on-demand PRS / SRS all belong to the same service base station, the service base station determines the time-frequency resource configuration parameters of the on-demand PRS / SRS, that is, determines the target positioning assistance data. When the TRP participating in sending or receiving on-demand PRS / SRS belongs to the service base station and the adjacent base station, the service base station and the adjacent base station respectively determine their respective time-frequency resource configuration parameters of the on-demand PRS / SRS, that is, the service base station and the adjacent base station respectively determine their respective corresponding target positioning assistance data. In this application, the case where the TRP participating in sending or receiving on-demand PRS / SRS belongs to the service base station and the adjacent base station is explained.

[0351] After receiving the positioning QoS information sent by the terminal device, the first network element determines the initial positioning assistance data according to the QoS information, which is similar to step 302. The specific content can be referred to the description of step 302 and will not be repeated here.

[0352] After determining the initial positioning assistance data, the first network element sends the initial positioning assistance data to the first network device and the second network device.

[0353] It is understandable that, in the case of multiple terminal devices, the first network element may also send the determined priority of each terminal device to the first network device and the second network device, and the first network device and the second network device each determine the target positioning QoS information based on the priority. After determining the target positioning QoS information, the second network device determines the initial positioning assistance data based on the target positioning QoS information determined by itself, which is similar to the way the first network device determines the initial positioning assistance data, and will not be repeated here.

[0354] Alternatively, the first network element may directly send the received positioning QoS information to the first network device and the second network device, and the first network device and the second network device may determine the positioning assistance data. The case where the first network device and the second network device determine the positioning assistance data will be described in detail below.

[0355] Step 403: The first network device determines first target positioning assistance data based on the positioning QoS information or the initial positioning assistance data, and the second network device determines second target positioning assistance data based on the positioning QoS information or the initial positioning assistance data.

[0356] If the second message includes the terminal device's positioning QoS information, the first network device determines the first target's positioning assistance data based on the positioning QoS information, and the second network device determines the second target's positioning assistance data based on the positioning QoS information. The first and second network devices determine the target's positioning assistance data in a similar manner, and both can be referred to the description in step 303, which will not be repeated here.

[0357] If the second message includes initial positioning assistance data corresponding to the positioning QoS information, the first network device can directly determine the initial positioning assistance data determined by the first network element as the first target positioning assistance data, thereby improving the efficiency of determining the first target positioning assistance data. In addition, the first network device can also adjust the initial positioning assistance data based on resource allocation to obtain the first target positioning assistance data, thereby improving resource utilization.

[0358] Similarly, the second network device can directly use the initial positioning assistance data determined by the first network element as the second target positioning assistance data, thereby improving the efficiency of determining the second target positioning assistance data. Furthermore, the second network device can also adjust the initial positioning assistance data based on resource allocation to obtain the second target positioning assistance data, thereby improving resource utilization.

[0359] Step 404: The first network element receives the first target positioning assistance data sent by the first network device and the second target positioning assistance data sent by the second network device respectively.

[0360] The first target positioning assistance data and the second target positioning assistance data are both related to positioning QoS information.

[0361] Since the first target positioning assistance data and the second target positioning assistance data are both related to the positioning QoS information, different target positioning assistance information can be allocated to different terminal devices according to the positioning QoS information of the terminal device, thereby not only ensuring the positioning accuracy and positioning delay of the terminal device, but also reducing the overhead of system resources and reducing resource waste.

[0362] Step 405: The first network element sends the first target positioning assistance data and the second target positioning assistance data to the terminal device.

[0363] In this step, after receiving the first target positioning assistance data and the second target positioning assistance data, the first network element sends the first target positioning assistance data and the second target positioning assistance data to the terminal device.

[0364] Step 406: The first network element receives the first positioning measurement value and the second positioning measurement value sent by the terminal device.

[0365] Among them, the first positioning measurement value is obtained by the terminal device receiving the first downlink positioning reference signal sent by the first network device according to the first target positioning assistance data, and measuring the first downlink positioning reference signal; the second positioning measurement value is obtained by the terminal device receiving the second downlink positioning reference signal sent by the second network device according to the second target positioning assistance data, and measuring the second downlink positioning reference signal.

[0366] In this step, if the positioning method determined by the first network element is a downlink positioning method, after receiving the first target positioning assistance data and the second target positioning assistance data sent by the first network element, the terminal device will determine the time-frequency resource configuration parameters of the first downlink positioning reference signal PRS based on the first target positioning assistance data, and receive the first downlink positioning reference signal PRS sent by the first network device based on the time-frequency resource configuration parameters of the first downlink positioning reference signal PRS, and measure the first downlink positioning reference signal PRS, thereby obtaining a first positioning measurement value. Similarly, the terminal device can determine the time-frequency resource configuration parameters of the second downlink positioning reference signal PRS based on the second target positioning assistance data, and receive the second downlink positioning reference signal PRS sent by the second network device based on the time-frequency resource configuration parameters of the second downlink positioning reference signal PRS, and measure the second downlink positioning reference signal PRS, thereby obtaining a second positioning measurement value.

[0367] After determining the first positioning measurement value and the second positioning measurement value, the terminal device may send the first positioning measurement value and the second positioning measurement value to the first network element.

[0368] Step 407: The first network element determines the location information of the terminal device based on the first positioning measurement value and the second positioning measurement value.

[0369] In this step, after the first network element obtains the first positioning measurement value and the second positioning measurement value, it will combine the location information of the first network device and the second network device to calculate the location information of the terminal device.

[0370] In the positioning method of a terminal device provided in an embodiment of the present application, a first message received by a first network element from a terminal device includes positioning QoS information. The first network element can determine initial positioning assistance data based on the positioning QoS information and send the initial positioning assistance data to the first network device and the second network device, or the first network element can directly send the positioning QoS information to the first network device and the second network device, so that the first network device and the second network device determine the first target positioning assistance data and the second target positioning assistance data based on the initial positioning assistance data or the positioning QoS information, so that the first network element can obtain a first positioning measurement value corresponding to the first target positioning assistance data and a second positioning measurement value corresponding to the second target positioning assistance data to determine the location information of the terminal device. Since the first network device and the second network device can consider the positioning QoS information of each terminal device when allocating the first target positioning assistance data to the terminal device, the corresponding first target positioning assistance data can be allocated to each terminal device according to the positioning QoS information of each terminal device, instead of uniformly allocating positioning assistance data to all terminal devices. In this way, since the positioning QoS information of each terminal device is taken into consideration when allocating positioning assistance data to the terminal device, not only the positioning accuracy and positioning delay of the terminal device can be guaranteed, but also the overhead of system resources can be reduced, thereby reducing resource waste.

[0371] The following describes in detail the implementation of uplink positioning, downlink positioning, and uplink and downlink combined (uplink + downlink) positioning using specific examples.

[0372] Figure 5 This is a signaling flow chart for determining the positioning information of the terminal device using the uplink positioning method in this application. In this embodiment, the first network element is LMF, the first network device is the service base station of the terminal device, the second network device is the adjacent base station of the terminal device, and the first network element determines the initial positioning assistance data according to the correspondence between the pre-stored positioning QoS information, the configuration parameters of the positioning reference signal and the threshold value corresponding to the configuration parameters. For other situations described in the aforementioned embodiments, the implementation process is similar to that in this embodiment and will not be repeated here. Figure 5 As shown, the method includes:

[0373] Step 501: The terminal device sends a first message to the LMF, where the first message includes positioning QoS information.

[0374] Step 502: The LMF determines the value of the configuration parameter corresponding to the positioning QoS information according to the correspondence between the pre-stored positioning QoS information, the configuration parameter of the positioning reference signal, and the threshold value corresponding to the configuration parameter.

[0375] For example, assuming that the threshold values in Table 1 are: X_th=100, Y_th=6, Z_th=5, T1_th=20, T2_th=100, the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters can be shown in Table 2:

[0376] Table 2

[0377]

[0378]

[0379] Step 503: The LMF determines the value of the configuration parameter as the initial positioning assistance data.

[0380] Step 504: The LMF sends a second message to the serving base station, where the second message includes initial positioning assistance data.

[0381] Step 505: The serving base station determines first target positioning assistance data based on the initial positioning assistance data, where the first target positioning assistance data is related to the positioning QoS information of the terminal device.

[0382] Step 506: The serving base station sends the first target positioning assistance data to the LMF and the terminal device respectively.

[0383] Step 507: The LMF sends first target positioning assistance data to the adjacent base station.

[0384] Step 508: The terminal device sends an uplink positioning reference signal SRS-Pos to the serving base station and the neighboring base station respectively according to the first target positioning assistance data.

[0385] Step 509: The serving base station measures the uplink positioning reference signal SRS-Pos to obtain a first positioning measurement value, and the neighboring base station measures the uplink positioning reference signal SRS-Pos to obtain a second positioning measurement value.

[0386] Step 510: The serving base station reports the first positioning measurement value to the LMF, and the neighboring base station reports the first positioning measurement value to the LMF.

[0387] Step 511: The LMF determines the location information of the terminal device based on the first positioning measurement value, the second positioning measurement value, the location of the serving base station, and the location of the adjacent base station.

[0389] It should be understood that Figure 5 The execution order of the steps shown in the figure is not limited.

[0390] In the positioning method of a terminal device provided in an embodiment of the present application, the first message received by the LMF from the terminal device includes positioning QoS information. The LMF can determine the initial positioning assistance data based on the positioning QoS information and send the initial positioning assistance data to the serving base station so that the serving base station allocates the first target positioning assistance data to the terminal device, so that the LMF can obtain the positioning measurement value corresponding to the first target positioning assistance data to determine the location information of the terminal device. Since the serving base station can consider the positioning QoS information of each terminal device when allocating the first target positioning assistance data to the terminal device, the corresponding first target positioning assistance data is allocated to each terminal device based on the positioning QoS information of each terminal device, instead of uniformly allocating positioning assistance data to all terminal devices. In this way, since the positioning QoS information of each terminal device is taken into account to allocate positioning assistance data to the terminal device, not only the positioning accuracy and positioning delay of the terminal device can be guaranteed, but also the overhead of system resources can be reduced, and the waste of resources can be reduced.

In this embodiment, the first network element is LMF, the first network device is the service base station of the terminal device, the second network device is the adjacent base station of the terminal device, and the first network element determines the initial positioning assistance data according to the correspondence between the pre-stored positioning QoS information, the configuration parameters of the positioning reference signal and the threshold value corresponding to the configuration parameters. For other situations described in the aforementioned embodiments, the implementation process is similar to that in this embodiment and will not be repeated here. Figure 6 As shown, the method includes:

[0393] Step 602: The LMF determines the value of the configuration parameter corresponding to the positioning QoS information according to the correspondence between the pre-stored positioning QoS information, the configuration parameter of the positioning reference signal, and the threshold value corresponding to the configuration parameter.

[0394] For example, assuming that the threshold values in Table 1 are fixed values, specifically: X_th=100, Y_th=4, Z_th=10, T1_th=20, T2_th=100, then the correspondence between the positioning QoS information, the configuration parameters of the positioning reference signal, and the threshold values corresponding to the configuration parameters can be shown in Table 3:

[0403] Step 608: The LMF sends the first target positioning assistance data and the second target positioning assistance data to the terminal device.

[0404] Step 609: The terminal device receives the downlink positioning reference signal PRS sent by the serving base station according to the first target positioning assistance data corresponding to the serving base station, and receives the downlink PRS sent by the adjacent base station according to the second target positioning assistance data corresponding to the adjacent base station.

[0405] Step 610: The terminal device measures the downlink PRS sent by the serving base station to obtain a first positioning measurement value corresponding to the serving base station, and measures the downlink PRS sent by the adjacent base station to obtain a second positioning measurement value corresponding to the adjacent base station.

[0406] Step 611: The terminal device reports the first positioning measurement value corresponding to the serving base station and the second positioning measurement value corresponding to the adjacent base station to the LMF.

[0407] Step 612: LMF determines the location information of the terminal device based on the first positioning measurement value corresponding to the serving base station, the second positioning measurement value corresponding to the adjacent base station, the location of the serving base station and the location of the adjacent base station.
