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

[0002] like Figure 1 As shown, it is a schematic diagram of the positioning architecture based on the evolved packet core (EPC). The positioning system is based on the architecture of enhanced serving mobile location centre (E-SMLC) control, access network and terminal assistance.

[0003] like Figure 2 As shown, based on Figure 1 The schematic diagram of the EPC positioning architecture for positioning measurement is shown, in which the terminal interacts with the E-SMLC for positioning capability in step 1 / 2; in step 3, the E-SMLC transmits auxiliary information to the terminal; in step 4 / 5, the reception and response of the measurement request are completed; after step 6, the terminal enters the idle state; in step 7, the terminal performs positioning measurement in the idle state; in step 8, the terminal re-enters the connected state; in step 9, the terminal reports the measurement result to the E-SMLC.

[0004] However, this positioning method performs measurements according to the measurement transmission time specified in step 4 / 5, without an additional measurement trigger mechanism, and the measurement power consumption is relatively large. In addition, in order to report the measurement results, the terminal needs to enter a connected state, which consumes a lot of power.

[0107] Figure 3 FIG. 1 is a schematic diagram of the architecture of a positioning system using the terminal positioning method of an embodiment of the present application. Figure 3 As shown, the positioning system includes a terminal, one or more access network devices ( Figure 3 An access network device is used as an example for illustration) and a positioning device. Among them, the terminal, the access network device or the positioning device can communicate directly with each other, or can communicate through forwarding of other devices, which is not specifically limited in the embodiment of the present application. Although not shown, the positioning system can also include other network elements such as a mobile management network element, which is not specifically limited in the embodiment of the present application.

The network element or entity corresponding to the above-mentioned mobile management network element may be an access and mobility management function (AMF) network element in the 5G mobile communication system, and the embodiments of the present application do not specifically limit this.

[0110] For example, Figure 4 FIG. 1 is a schematic diagram of the architecture of a positioning system for applying the terminal positioning method of an embodiment of the present application in a 5G mobile communication system.

[0111] For example, Figure 5 A schematic diagram of the architecture of another positioning system for applying the positioning method of an embodiment of the present application in a 5G mobile communication system. Figure 5 and Figure 4 The difference between the positioning system architecture is that Figure 4 The device or component (such as LMF network element) of the positioning management function is deployed in the core network.

Figure 5 As shown in the figure, the gNB includes the LMC network element. The LMC network element is a partial functional component of the LMF network element and can be integrated in the gNB of the NG-RAN device.

[0114] As an example but not limitation, in an embodiment of the present application, the terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality terminal, an augmented reality terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc.

[0115] As an example and not a limitation, in the embodiments of the present application, wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0116] In addition, in the embodiment of the present application, the terminal may also be a terminal in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. In the embodiment of the present application, IOT technology can achieve massive connections, deep coverage, and terminal power saving through, for example, narrow band (NB) technology.

[0117] In addition, in an embodiment of the present application, the terminal may also include sensors such as smart printers, train detectors, gas stations, etc., and its main functions include collecting data (partial terminals), receiving control information and downlink data from access network devices, and sending electromagnetic waves to transmit uplink data to access network devices.

[0118] Optionally, the access network device in the embodiment of the present application can be any communication device with wireless transceiver function for communicating with the terminal.

In addition, the access network device can also be a network node constituting a gNB or TP, such as a BBU, or a distributed unit (DU), etc.

[0119] In some deployments, the gNB may include a centralized unit (CU) and a DU. In addition, the gNB may also include an active antenna unit (AAU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY). The AAU implements some physical layer processing functions, RF processing, and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this architecture, high-level signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by the DU+AAU. It can be understood that the access network device can be a device including one or more of a CU node, a DU node, and an AAU node.

[0120] Optionally, the access network device and the terminal in the embodiment of the present application can communicate through the authorized spectrum, can communicate through the unlicensed spectrum, or can communicate through both the authorized spectrum and the unlicensed spectrum. The access network device and the terminal can communicate through the spectrum below 6 gigahertz (GHz), can communicate through the spectrum above 6 GHz, or can communicate using the spectrum below 6 GHz and the spectrum above 6 GHz at the same time. The embodiment of the present application does not limit the spectrum resources used between the access network device and the terminal 101.

[0121] Optionally, the terminal, access network device or positioning device in the embodiments of the present application can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the terminal, access network device or positioning device.

[0122] Optionally, in an embodiment of the present application, a terminal or access network device or positioning device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and a memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through a process, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a windows operating system. The application layer includes applications such as a browser, an address book, a word processing software, and an instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application, as long as it can communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be a terminal or an access network device or a positioning device, or a functional module in a terminal or an access network device or a positioning device that can call a program and execute the program.

[0123] In other words, the relevant functions of the terminal, access network device or positioning device in the embodiments of the present application can be implemented by one device, or by multiple devices together, or by one or more functional modules in one device, and the embodiments of the present application do not specifically limit this. It is understandable that the above functions can be network elements in hardware devices, or software functions running on dedicated hardware, or a combination of hardware and software, or virtualization functions instantiated on a platform (e.g., a cloud platform).

[0124] For example, the relevant functions of the terminal, access network device or positioning device in the embodiment of the present application can be Figure 6 The communication device 600 is implemented. Figure 6 FIG. 6 is a schematic diagram of the structure of a communication device 600 provided in an embodiment of the present application. The communication device 600 includes one or more processors 601, a communication line 602, and at least one communication interface ( Figure 6 The example in which the communication interface 604 and a processor 601 are included is merely exemplary), and a memory 603 may also be included optionally.

[0125] The processor 601 may be a central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application.

Optionally, the communication interface 604 may also be a transceiver circuit located in the processor 601 to implement signal input and signal output of the processor.

[0128] The memory 603 may be a device with a storage function. For example, it may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory may exist independently and be connected to the processor via a communication line 602. The memory may also be integrated with the processor.

[0129] The memory 603 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 601. The processor 601 is used to execute the computer-executable instructions stored in the memory 603, thereby realizing the positioning method provided in the embodiment of the present application.

[0130] Alternatively, in the embodiment of the present application, the processor 601 may also perform processing-related functions in the positioning method provided in the following embodiments of the present application, and the communication interface 604 is responsible for communicating with other devices or communication networks, which is not specifically limited in the embodiment of the present application.

[0131] The computer-executable instructions in the embodiments of the present application may also be referred to as application program codes, which is not specifically limited in the embodiments of the present application.

[0136] The following will be combined Figures 1 to 6 The terminal positioning method provided in the embodiment of the present application is described in detail.

[0137] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are merely examples, and other names may be used in specific implementations, and the embodiments of the present application do not impose any specific limitations on this.

[0138] like Figure 7 As shown, it is a schematic diagram of the process of the terminal positioning method provided in an embodiment of the present application, and the method may include the following steps:

[0139] S101. When a terminal is in an idle state or an inactive state, a positioning device sends a paging message, where the paging message is used to indicate a trigger state of the terminal, where the trigger state is used to instruct the terminal to send an uplink reference signal for positioning, or to instruct the terminal to measure a downlink reference signal for positioning.

[0140] Correspondingly, the terminal receives the paging message.

[0141] When there is no data transmission, the terminal enters the idle state or the inactive state. The idle state means that the access network device serving the terminal sends a radio resource control-release (RRCRelease) message to the terminal and deletes the context of the terminal. After the terminal receives the RRCRelease message, it enters the idle state. The inactive state means that the access network device serving the terminal sends a RRCRelease message containing a suspend configuration (SuspendConfig) to the terminal and retains the context of the terminal. After the terminal receives the RRCRelease message containing the suspend configuration, it enters the inactive state.

[0142] When the positioning device performs terminal positioning, it needs to obtain the uplink reference signal sent by the terminal for uplink positioning, or obtain the measurement result of the downlink reference signal of the terminal for downlink positioning, or obtain the uplink reference signal sent by the terminal for uplink positioning and obtain the measurement result of the downlink reference signal of the terminal for downlink positioning. If the terminal is currently in an idle state or an inactive state, the positioning device can send a positioning request to the AMF or the access network device registered by the terminal, and the AMF or the access network device registered by the terminal sends a paging message to the terminal.

[0143] The paging information can be carried in a paging message or in the scheduling information of the paging message. The paging information is used to indicate the trigger state of the terminal, and the trigger state is used to indicate the terminal to send an uplink reference signal for positioning, or to indicate the terminal to measure a downlink reference signal for positioning. The trigger state is specifically a state in a trigger state set, and the trigger state set includes one or more of the following trigger states: no triggering; triggering the sending of one or more uplink reference signal sets; triggering the measurement of one or more downlink reference signal sets; stopping the sending of one or more uplink reference signal sets; stopping the sending of all uplink reference signal sets; stopping the measurement of one or more downlink reference signal sets; stopping the measurement of all downlink reference signal sets; triggering the reporting of measurement results of one or more downlink reference signal sets; triggering the reporting of the first information; determining the action of the terminal according to other trigger states, etc.

[0144] The terminal receives the paging information, and performs the operation indicated by the trigger state according to the trigger state indicated by the paging information. For example, the paging information includes 2 bits. If the bit value of the paging information is 00, the corresponding trigger state is not triggered, and the terminal does not send an uplink reference signal and does not measure the downlink reference signal; for another example, if the bit value of the paging information is 01, the corresponding trigger state is to trigger the sending of one or more uplink reference signal sets, and the terminal sends the above one or more uplink reference signal sets; for another example, if the bit value of the paging information is 10, the corresponding trigger state is to trigger the measurement of one or more downlink reference signal sets, and the terminal measures the above one or more downlink reference signal sets; and so on.

[0145] The foregoing Figure 2 In the terminal positioning technology shown, since it is stipulated that the terminal cannot send an uplink reference signal when it is in an idle state, the positioning technology only supports downlink-based positioning, does not support uplink positioning, and has low positioning accuracy. In this embodiment, the paging information can trigger the terminal to send an uplink reference signal for positioning, or trigger the terminal to measure a downlink reference signal for positioning, or trigger the terminal to send an uplink reference signal for positioning and measure a downlink reference signal for positioning, so that the terminal can measure the downlink reference signal for downlink positioning; it can also send an uplink reference signal for uplink positioning, thereby improving the positioning accuracy.

[0146] Furthermore, before the positioning device sends paging information to the terminal, the positioning device may also obtain the configuration information of the downlink reference signal of the access network device serving the terminal and the access network device in the neighboring area, and obtain the configuration information of the uplink reference signal of the access network device serving the terminal. And when the terminal is in a connected state, the positioning device may send the configuration information of the downlink reference signal, or the configuration information of the uplink reference signal to the terminal.

[0147] S102. The terminal measures a downlink reference signal according to configuration information of the downlink reference signal.

[0148] According to the trigger state indicated by the paging information, if the indicated trigger state is to trigger the measurement of one or more downlink reference signal sets, the terminal measures the one or more downlink reference signal sets. Specifically, the access network device serving the terminal and the neighboring access network device send a downlink reference signal at the time-frequency resource position configured by the configuration information of the downlink reference signal, and the terminal receives the above-mentioned downlink reference signal at the time-frequency resource position. The downlink reference signal includes a synchronization signal / physical broadcast channel (SS / PBCH block) and a positioning reference signal (PRS).

[0149] Specifically, for a downlink reference signal sent by any TRP of the access network device serving the terminal or the neighboring access network device, if a TRP corresponds to a downlink reference signal set, a downlink reference signal set includes one or more downlink reference signals, and each downlink reference signal of the downlink reference signal set of the TRP represents a beam, the terminal receives the downlink reference signal sent by the TRP on multiple beams and performs measurements to obtain the measurement results of the downlink reference signal.

[0150] The measurement result of the downlink reference signal includes one or more of the following measurement quantities: downlink reference signal time difference (DL RSTD), downlink positioning reference signal reference signal received power (DL PRS-RSRP), terminal transmit-receive time difference (UE Rx-Tx time difference), synchronization signal reference signal received power (SS-RSRP), synchronization signal reference signal received quality (SS-RSRQ). The downlink reference signal can be measured using one or more of the above measurement quantities.

[0151] S103': The terminal sends an uplink reference signal to the access network device according to the configuration information of the uplink reference signal.

[0152] Correspondingly, the access network device receives the uplink reference signal according to the configuration information of the uplink reference signal. The access network device may be an access network device serving the terminal or an access network device in a neighboring area.

[0153] S104: The access network device measures the uplink reference signal to obtain a measurement result of the uplink reference signal.

[0154] S105. The access network device sends a measurement result of a downlink reference signal to the positioning device.

[0155] Correspondingly, the positioning device receives the measurement result of the uplink reference signal from the access network device.

[0156] S103”, the terminal device sends the measurement result of the downlink reference signal to the positioning device.

[0157] Correspondingly, the positioning device receives the measurement result of the downlink reference signal from the terminal.

[0158] The terminal is still in an idle state or an inactive state. The terminal sends an uplink reference signal according to the configuration information of the uplink reference signal according to the trigger state indicated by the paging information. Specifically, the uplink reference signal is sent at the time-frequency resource position of the uplink reference signal according to the period of the uplink reference signal. The uplink reference signal includes a sounding reference signal (SRS) and a random access preamble.

[0159] If the paging information triggers the measurement and reporting of the downlink reference signal, the terminal sends the measurement result of the downlink reference signal after obtaining the measurement result of the downlink reference signal.

[0160] It can be understood that if the paging information triggers the sending of the uplink reference signal and the measurement and sending of the downlink reference signal, the terminal measures the downlink reference signal and sends the measurement results of the uplink reference signal and the downlink reference signal, the access network device measures the uplink reference signal, and sends the measurement result of the uplink reference signal to the positioning device, that is, executing steps S102 to S105; if the paging information only triggers the sending of the uplink reference signal, the terminal sends the uplink reference signal, the access network device measures the uplink reference signal, and sends the measurement result of the uplink reference signal to the positioning device, that is, executing steps S103' to S105; if the paging information only triggers the measurement and sending of the downlink reference signal, the terminal measures and sends the downlink reference signal, that is, executing steps S102 and S103".

[0161] S106: The positioning device positions the terminal according to the measurement result of the uplink reference signal or the measurement result of the downlink reference signal.

[0162] The positioning device receives the uplink reference signal measurement result sent by the access network device and can perform uplink positioning on the terminal; or, the positioning device receives the downlink reference signal measurement result sent by the terminal and can perform downlink positioning on the terminal; or the positioning device receives both the uplink reference signal measurement result sent by the access network device and the downlink reference signal measurement result sent by the terminal and can perform uplink and downlink positioning on the terminal.

[0163] According to the terminal positioning method provided in the embodiment of the present application, the positioning device can trigger the terminal to send an uplink reference signal or measure a downlink reference signal through paging information at any time as needed. The terminal does not need to send or measure at the prescribed measurement sending time, and the measurement result of the uplink reference signal or the downlink reference signal can be sent when the terminal is in an idle state or an inactive state, thereby saving the power consumption of the terminal; and the positioning device supports positioning based on uplink and downlink, thereby improving positioning accuracy.

[0164] like Figure 8 As shown, it is another flowchart of the terminal positioning method provided in the embodiment of the present application, and the method may include the following steps:

[0165] S201. The first access network device sends configuration information of an uplink reference signal to a positioning device through an AMF, or the first access network device sends configuration information of a downlink reference signal to a positioning device through an AMF.

[0166] Correspondingly, the positioning device receives the configuration information of the uplink reference signal or the configuration information of the downlink reference signal sent by the first access network device. The first access network device is an access network device serving the terminal, and may also be called a serving cell.

[0167] In addition, the neighboring cell access network device (not shown in the figure) sends the configuration information of the downlink reference signal to the positioning device through the AMF, and the positioning device receives the configuration information of the downlink reference signal sent by the neighboring cell access network device.

[0168] In this embodiment, the positioning device and the terminal have established a connection in the connected state and started the LTE positioning protocol (LTE positioning protocol, LPP). At the same time, the positioning device and the terminal have exchanged terminal positioning capabilities, for example, the terminal reports that it supports downlink reference signal measurement, reporting, or uplink reference signal transmission based on paging triggering. In addition, the positioning device also requests and obtains physical layer resource configuration, such as uplink reference signal configuration, from the first access network device.

[0169] The first access network device pre-configures an uplink reference signal, which includes a sounding reference signal and a random access preamble.

[0170] The configuration information of the uplink reference signal includes one or more of the following information:

[0171] The time and frequency information of the detection reference signal, the period, port, and code information of the detection reference signal, the time and frequency information of the random access preamble, the period of the random access preamble, and the association between the random access preamble and the synchronization signal / physical layer broadcast signal block. The first access network device sends the configuration information of the above-mentioned uplink reference signal to the positioning device through the AMF, and when the terminal is in a connected state, the positioning device sends the configuration information of the above-mentioned uplink reference signal to the terminal.

[0172] The first access network device and the neighboring access network device (also referred to as the neighboring cell) pre-configure the downlink reference signal. The downlink reference signal may be an SS / PBCH block or a PRS, etc. The first access network device and the neighboring access network device send the configuration information of the downlink reference signal to the positioning device through the AMF.

[0173] Specifically, one or more TRPs of the first access network device and the neighboring access network device respectively send configuration information of the downlink reference signal set of the one or more TRPs. The configuration information of the downlink reference signal includes one or more of the following information: time-frequency position information of SS / PBCH block, time-frequency position information of PRS, etc.

[0174] S202: The positioning device sends configuration information of a downlink reference signal or configuration information of an uplink reference signal to the terminal.

[0175] Specifically, the positioning device sends the configuration information of the downlink reference signal, or the configuration information of the uplink reference signal, to the terminal through the AMF and the first access network device. The positioning device sends the configuration information of the downlink reference signal, or the configuration information of the uplink reference signal to the terminal based on the LPP. The configuration information of the downlink reference signal includes the configuration information of the downlink reference signal sent by the above-mentioned first access network device and the neighboring access network device to the positioning device; the configuration information of the uplink reference signal includes the configuration information of the uplink reference signal sent by the above-mentioned first access network device to the positioning device.

[0176] Correspondingly, the terminal receives the configuration information of the downlink reference signal or the configuration information of the uplink reference signal.

[0177] S203. The positioning device sends measurement request information to the terminal through the AMF and the first access network device.

[0178] Correspondingly, the terminal receives the measurement request information. The measurement request information is based on LPP. The measurement request information is used to request the terminal to perform positioning.

[0179] The measurement request information is used to instruct the terminal to perform one or more of the following operations after receiving the paging information:

[0180] Measurement of downlink reference signals;

[0181] Transmission of uplink reference signals;

[0182] Reporting downlink reference signal measurement results;

[0183] Report the first information.

[0184] This means that after receiving the measurement request information, the terminal may not perform the above operation immediately, but postpone the above operation and perform the above operation after receiving the paging information.

[0185] In addition, the positioning device also configures a trigger state set of paging information, which is included in the measurement request information. According to the paging information carried in the paging message, or the scheduling information of the paging message (which may be downlink control information (DCI)), or the paging message and the scheduling information of the paging message, the trigger state set has the following implementations:

[0186] In one implementation, the paging information is carried in a paging message, and the measurement request information includes a first trigger state set. The first trigger state set includes one or more first trigger states.

[0187] The first trigger state includes one or more of the following trigger states:

[0188] does not trigger; or

[0189] triggering the transmission of one or more uplink reference signal sets; or

[0190] triggering measurement of one or more downlink reference signal sets; or

[0191] Stop sending one or more uplink reference signal sets; or

[0192] Stop sending all uplink reference signal sets; or

[0193] Stop measuring one or more downlink reference signal sets; or

[0194] Stop measuring all downlink reference signal sets; or

[0195] triggering reporting of measurement results of one or more downlink reference signal sets; or

[0196] Triggering reporting of the first information.

[0197] Furthermore, the measurement request information may also include one or more of the following information: the number of measurements of the downlink reference signal, the number of transmissions of the uplink reference signal, and the time interval between reporting the measurement result of the downlink reference signal and receiving the paging information. Among them, in order to improve the measurement accuracy of the downlink reference signal, the positioning device may carry the specific number of measurements of the downlink reference signal in the measurement request information. At the same time, in order to improve the measurement accuracy of the uplink reference signal, the positioning device may carry the specific number of transmissions of the uplink reference signal in the measurement request information. In addition, the time interval between reporting the measurement result of the downlink reference signal and receiving the paging information can also be flexibly configured. For example, the terminal device can be configured to measure the downlink reference signal immediately after receiving the paging information, and report the downlink reference signal measurement 5s after receiving the paging information, so that the terminal can flexibly measure and report according to its own situation. Correspondingly, the terminal can report the first information. The first information includes one or more of the following information: the actual number of transmissions of the uplink reference signal, and the index information of the resident cell. The positioning device can accurately obtain the measurement result of the uplink reference signal based on the actual transmission times of the uplink reference signal, thereby improving the measurement accuracy of the uplink reference signal. The positioning device can roughly locate the terminal based on the index information of the resident cell, thereby improving the efficiency of terminal positioning.

[0198] Exemplarily, the format of the first trigger state set is as follows:

[0199]

[0200]

[0201] It can be seen that for any triggering state, an operation on one or more reference signal resource sets in UL-RS-SetId or DL-RS-SetId can be triggered.

[0202] It can be understood that the first trigger state in the first trigger state set has a preset corresponding relationship with the bit value of the paging information. The number of configurable first trigger states is the total number of first trigger states minus 1, wherein a certain first trigger state in the first trigger state set is reserved as not triggered, and the bit value of the corresponding paging information is a state of all 0. For example, according to the configuration order of the first trigger state in the first trigger state set, the first trigger state in the first trigger state set is matched one-to-one with the non-all-0 bit value of the paging information. For example, the paging information includes 3 bits, 000 means not triggered; 001 means triggering the reception of the downlink reference signal set; 010 means triggering the reception of the downlink reference signal set and triggering the sending of the uplink reference signal; 011 means stopping the reception of the downlink reference signal set; 100 means triggering the reporting of the measurement result of the downlink reference signal; 101 means triggering the sending of the uplink reference signal set; and so on.

[0203] In another implementation, the paging information is carried in the scheduling information of the paging message, and the measurement request information further includes a second trigger state set. The second trigger state set includes one or more second trigger states. The number of second trigger states included in the second trigger state set may be the same as or different from the number of first trigger states included in the first trigger state set; the format of the second trigger state set may be the same as or different from the format of the first trigger state set.

[0204] In another implementation, the paging information is carried in the scheduling information of the paging message and the paging message, and the measurement request information also includes a third trigger state set and a fourth trigger state set. The fourth trigger state set includes one or more fourth trigger states. The format of the fourth trigger state included in the fourth trigger state set may be the same as or different from the number of first trigger states included in the first trigger state set; the format of the fourth trigger state set may be the same as or different from the format of the first trigger state set.

[0205] The third trigger state set includes one or more third trigger states, and the third trigger state includes one or more of the following trigger states:

[0206] does not trigger; or

[0207] Determined according to a fourth trigger state; or

[0208] triggering the transmission of one or more uplink reference signal sets; or

[0209] triggering measurement of one or more downlink reference signal sets; or

[0210] Stop sending one or more uplink reference signal sets; or

[0211] Stop sending all uplink reference signal sets; or

[0212] Stop measuring one or more downlink reference signal sets; or

[0213] Stop measuring all downlink reference signal sets; or

[0214] Triggering reporting of measurement results of triggering one or more downlink reference signal sets; or

[0215] Triggering reporting of the first information.

[0216] Exemplarily, the format of the third trigger state set is as follows:

[0217]

[0218] The difference between this implementation and the above implementation is that the third trigger state set also includes a third trigger state: upToPCH, which means that the trigger state indicated by the scheduling information depends on the fourth trigger state. The fourth trigger state is the trigger state indicated by the paging message carried on the paging channel (PCH) mapped by the physical downlink shared channel (PDSCH) scheduled by the scheduling information. That is, the trigger state is determined jointly according to the scheduling information of the paging message and the paging message.

[0219] S204. The first access network device sends a RRCRelease message to the terminal.

[0220] Correspondingly, the terminal receives the RRCRelease message.

[0221] When the terminal has no data transmission or the terminal moves out of the coverage of the first access network device, the first access network device may send an RRCRelease message to the terminal. The message is used to notify the terminal to release the RRC connection. The terminal enters the idle state.

[0222] S205. AMF notifies all access network devices in the tracking area (TA) to send paging information to the terminal.

[0223] Correspondingly, the terminal receives the paging information.

[0224] Specifically, since the terminal is in an idle state, the RRC connection between the terminal and the first access network device has been disconnected. Therefore, the AMF notifies all access network devices in the TA to send paging information to the terminal. The terminal receives the scheduling information of the paging message and periodically monitors the paging message on the paging occasion.

[0225] The paging information configured according to the measurement request information is carried in a paging message, or the scheduling information of the paging message, or the scheduling information of the paging message and the paging message. The paging message and the scheduling information of the paging message have the following implementations:

[0226] In one implementation, the scheduling information of the paging message is used to determine a physical downlink shared channel (PDSCH), the PDSCH mapped PCH carries the paging message, the paging message is used to page the terminal, and the paging message also carries the above paging information. That is, the paging message is also used to determine a first trigger state, and the first trigger state belongs to the first trigger state set. For example, according to the first trigger state set configured by the above-mentioned measurement request information, if the bit value corresponding to the paging information is 000, the corresponding trigger state is to trigger the sending of the uplink reference signal set; if the bit value corresponding to the paging information is 001, the corresponding trigger state is to trigger the reception of the downlink reference signal set; if the bit value corresponding to the paging information is 010, the corresponding trigger state is to stop the sending of the downlink reference signal set; if the bit value corresponding to the paging information is 011, the corresponding trigger state is to stop the reception of the downlink reference signal set; if the bit value corresponding to the paging information is 100, the corresponding trigger state is to trigger the reporting of the measurement result of the downlink reference signal; if the bit value corresponding to the paging information is 101, the corresponding trigger state is to trigger the sending of the uplink reference signal set; and so on.

[0227] In another implementation, the scheduling information of the paging message is used to schedule the paging message, and the scheduling information of the paging message also carries the above-mentioned paging information. That is, the scheduling information of the paging message is also used to determine a second trigger state, and the second trigger state belongs to the second trigger state set. The paging message is used to paging the terminal.

[0228] In another implementation, the scheduling information of the paging message is used to schedule the paging message, and the paging message is used to page the terminal. In addition, the paging message and the scheduling information of the paging message also carry the paging information. That is, the scheduling information of the paging message is also used to determine a third trigger state, and the third trigger state belongs to the third trigger state set; the paging message is also used to determine a fourth trigger state, and the fourth trigger state belongs to the fourth trigger state set. The paging information is determined based on the third trigger state and the fourth trigger state.

[0229] For example, the third trigger state set includes two third trigger states, wherein the correspondence between the two third trigger states and the bit values ​​of the paging information is: 0 indicates no triggering, and 1 indicates that it depends on the paging message (fourth trigger state). The trigger states in the fourth trigger state set have a preset correspondence with the bit values ​​of the paging information. For example, according to the configuration order of the trigger states in the fourth trigger state set, the trigger states in the fourth trigger state set are corresponded one-to-one with the bit values ​​of the paging information. For example, the paging information includes 3 bits, 000 indicates triggering the sending of the uplink reference signal set; 001 indicates triggering the reception of the downlink reference signal set; 010 indicates stopping the sending of the downlink reference signal set; 011 indicates stopping the reception of the downlink reference signal set; 100 indicates triggering the reporting of the measurement results of the downlink reference signal; 101 indicates triggering the sending of the uplink reference signal set; and so on. Then, if the bit value corresponding to the scheduling information of the paging message is 0, the terminal can ignore the bit value corresponding to the paging message and determine not to trigger any operation; if the bit value corresponding to the scheduling information of the paging message is 1, and the bit value corresponding to the paging message is 001, the terminal determines to trigger the reception of the downlink reference signal set; and so on.

[0230] S206. The terminal measures the downlink reference signal according to the configuration information of the downlink reference signal.

[0231] Taking the paging information carried in the scheduling information of the paging message as an example, the terminal receives the scheduling information of the paging message, and performs the operation indicated by the first trigger state according to the first trigger state indicated by the scheduling information of the paging message. For example, if the first trigger state is not triggered, the terminal does not send an uplink reference signal and does not measure the downlink reference signal; for another example, if the first trigger state is to trigger the sending of one or more uplink reference signal sets, the terminal sends the above one or more uplink reference signal sets; for another example, if the first trigger state is to trigger the measurement of one or more downlink reference signal sets, the terminal measures the above one or more downlink reference signal sets; and so on.

[0232] The terminal measures the one or more downlink reference signal sets according to the first trigger state indicated by the scheduling information of the paging message, if the indicated first trigger state is to trigger the measurement of one or more downlink reference signal sets. Specifically, the first access network device and the neighboring access network device send a downlink reference signal at the time-frequency resource position configured by the configuration information of the downlink reference signal, and the terminal receives the above-mentioned downlink reference signal at the time-frequency resource position. The downlink reference signal includes SS / PBCH block and PRS, etc.

[0233] Specifically, for a downlink reference signal sent by any TRP of the first access network device or the neighboring access network device, if a TRP corresponds to a downlink reference signal set, a downlink reference signal set includes one or more downlink reference signals, and each downlink reference signal of the downlink reference signal set of the TRP represents a beam, the terminal receives the downlink reference signal sent by the TRP on multiple beams and performs measurement to obtain the measurement result of the downlink reference signal.

[0234] The measurement result of the downlink reference signal includes one or more of the following measurement quantities: downlink reference signal time difference, reference signal received power of the downlink positioning reference signal, terminal transceiver time difference, reference signal received power of the synchronization signal, and reference signal received quality of the synchronization signal. The downlink reference signal can be measured using one or more of the above measurement quantities.

[0235] S207': The terminal sends a measurement result of a downlink reference signal, or first information, to the positioning device.

[0236] Correspondingly, the positioning device receives the measurement result of the downlink reference signal, or the first information. The first information includes one or more of the following information: the actual number of times the uplink reference signal is sent, and the index information of the resident cell. The positioning device can accurately obtain the measurement result of the uplink reference signal based on the actual number of times the uplink reference signal is sent, thereby improving the measurement accuracy of the uplink reference signal; the positioning device can roughly locate the terminal based on the obtained index information of the resident cell, thereby improving the efficiency of terminal positioning.

[0237] S207". The terminal sends an uplink reference signal according to the configuration information of the uplink reference signal.

[0238] Correspondingly, the access network device receives the uplink reference signal. The access network device may be all access network devices in the TA. All access network devices in the TA may include the above-mentioned first access network device, or may not include the above-mentioned first access network device. In this example, it is described that all access network devices in the TA may include the above-mentioned first access network device.

[0239] S208. The first access network device measures the uplink reference signal to obtain a measurement result of the uplink reference signal.

[0240] Similarly, other access network devices in the TA also measure the uplink reference signal to obtain measurement results of the uplink reference signal.

[0241] S209. The first access network device sends a measurement result of an uplink reference signal to the positioning device.

[0242] Correspondingly, the positioning device receives the measurement result of the uplink reference signal.

[0243] The terminal is still in an idle state or an inactive state. The terminal sends an uplink reference signal according to the configuration information of the uplink reference signal at the time-frequency resource position of the uplink reference signal and according to the period of the uplink reference signal, etc. The uplink reference signal includes a sounding reference signal and a random access preamble, etc., according to the first trigger state indicated by the scheduling information of the paging message.

[0244] If the paging information triggers the measurement and reporting of the downlink reference signal, the terminal sends the measurement result of the downlink reference signal after obtaining the measurement result of the downlink reference signal.

[0245] It can be understood that if the scheduling information of the paging message triggers the sending of the uplink reference signal and the measurement and sending of the downlink reference signal, the terminal measures the downlink reference signal, and sends the measurement results of the uplink reference signal to the access network device and the downlink reference signal to the positioning device, and the access network device measures the uplink reference signal and sends the measurement results of the uplink reference signal to the positioning device, that is, executes steps S206 to S209; if the scheduling information of the paging message only triggers the sending of the uplink reference signal, the terminal sends the uplink reference signal, the access network device measures the uplink reference signal, and sends the measurement results of the uplink reference signal to the positioning device, that is, executes steps S207" to S209; if the scheduling information of the paging message only triggers the measurement and sending of the downlink reference signal, the terminal measures and sends the downlink reference signal, and executes the sending of the measurement results of the downlink reference signal in S206 and S207'.

[0246] In addition, the terminal may also report the above-mentioned first information.

[0247] Since the time-frequency resources of the uplink reference signal have been configured, the terminal can use the time-frequency resources to send the uplink reference signal.

[0248] The terminal also sends a measurement result of the downlink reference signal, or the first information, in the following manner:

[0249] In one implementation, the terminal sends the measurement result of the downlink reference signal, or the first information, through message 3 of the four-step random access without entering the connected state. Among them, for contention-based random access, when the terminal is in the idle state, random access can be performed through four steps: the terminal sends message 1 (preamble); the terminal receives a random access response (RAR) sent by the access network device, that is, message 2; the terminal sends an uplink message on the allocated uplink resource according to the instruction of the RAR, that is, message 3; the access network device receives the uplink message of the terminal and returns a conflict resolution message to the terminal that has successfully accessed, that is, message 4. In this embodiment, the measurement result of the downlink reference signal, or the first information, can be carried in message 3 without entering the connected state.

[0250] In another implementation, the terminal sends the measurement result of the downlink reference signal, or the first information, through message A of the 2-step random access without entering the connected state. The 2-step random access means that the terminal sends the message 1 and message 3 of the above 4-step random access as a message (i.e., message A), and the access network device sends the message 2 and message 4 of the above 4-step random access as a message (i.e., message B). In this embodiment, the measurement result of the downlink reference signal, or the first information, can be carried in message A without entering the connected state.

[0251] In another implementation, the terminal sends the measurement result of the downlink reference signal, or the first information, through the pre-configured physical layer uplink shared channel resource without entering the connected state. The access network device pre-configures the physical layer uplink shared channel resource for the terminal, and the terminal can send the measurement result of the downlink reference signal, or the first information, on the pre-configured physical layer uplink shared channel resource without entering the connected state.

[0252] In another implementation, the terminal sends the measurement result of the downlink reference signal or the first information through the physical layer uplink shared channel resource after entering the connected state. The terminal may also send the measurement result of the downlink reference signal or the first information through the physical layer uplink shared channel resource after entering the connected state.

[0253] S210: The positioning device positions the terminal according to the measurement result of the uplink reference signal or the measurement result of the downlink reference signal.

[0254] The access network equipment in the TA blindly detects whether the terminal sends an uplink reference signal at the time-frequency resource position of the uplink reference signal. If the uplink reference signal sent by the terminal is detected, the uplink reference signal is measured to obtain the measurement result of the uplink reference signal. The access network equipment in the TA sends the measurement result of the uplink reference signal to the positioning device.

[0255] The access network device where the terminal resides in the TA receives the measurement result of the downlink reference signal sent by the terminal, and sends the measurement result of the downlink reference signal to the positioning device through the AMF.

[0256] The positioning device can perform uplink positioning of the terminal based on the measurement result of the received uplink reference signal; or, the positioning device can perform downlink positioning of the terminal based on the measurement result of the received downlink reference signal; or, the positioning device can perform uplink and downlink positioning of the terminal based on the measurement result of the received uplink reference signal and the measurement result of the downlink reference signal.

[0257] According to the terminal positioning method provided in the embodiment of the present application, the positioning device can trigger the terminal to send an uplink reference signal or measure a downlink reference signal through paging information at any time as needed. The terminal does not need to send or measure at the prescribed measurement sending time, and the measurement result of the uplink reference signal or the downlink reference signal can be sent when the terminal is in an idle state or an inactive state, thereby saving the power consumption of the terminal; and the positioning device supports positioning based on uplink and downlink, thereby improving positioning accuracy.

[0258] like Fig. 9 As shown, it is another flowchart of the terminal positioning method provided in the embodiment of the present application, and the method may include the following steps:

[0259] S301. The first access network device sends configuration information of an uplink reference signal to a positioning device through an AMF, or the first access network device sends configuration information of a downlink reference signal to a positioning device through an AMF.

[0260] Correspondingly, the positioning device receives the configuration information of the uplink reference signal or the configuration information of the downlink reference signal sent by the first access network device. The first access network device is an access network device serving the terminal.

[0261] In addition, the neighboring cell access network device (not shown in the figure) sends the configuration information of the downlink reference signal to the positioning device through the AMF, and the positioning device receives the configuration information of the downlink reference signal sent by the neighboring cell access network device.

[0262] For specific implementation, please refer to Figure 8 Step S201 in the illustrated embodiment will not be described in detail here.

[0263] S302: The positioning device sends configuration information of a downlink reference signal or configuration information of an uplink reference signal to the terminal.

[0264] Correspondingly, the terminal receives the configuration information of the downlink reference signal or the configuration information of the uplink reference signal.

[0265] For specific implementation, please refer to Figure 8Step S202 in the illustrated embodiment will not be described in detail here.

[0266] S303. The positioning device sends measurement request information to the terminal through the AMF and the first access network device.

[0267] Correspondingly, the terminal receives the measurement request information. The measurement request information is based on LPP. The measurement request information is used to request the terminal to perform positioning.

[0268] The measurement request information is used to instruct the terminal to perform one or more of the following operations after receiving the paging information:

[0269] Measurement of downlink reference signals;

[0270] Transmission of uplink reference signals;

[0271] Reporting downlink reference signal measurement results;

[0272] Report the first information.

[0273] This means that after receiving the measurement request information, the terminal may not perform the above operation immediately, but postpone the above operation and perform the above operation after receiving the paging information.

[0274] In addition, the positioning device also configures a trigger state set of the paging information, and the trigger state set is included in the measurement request information.

[0275] For specific implementation, please refer to Figure 8 Step S203 in the illustrated embodiment will not be described in detail here.

[0276] S304. The first access network device sends a RRCRelease message including a suspend configuration (SuspendConfig) to the terminal.

[0277] Correspondingly, the terminal receives the RRCRelease message including the suspension configuration.

[0278] This embodiment and Figure 8 One difference of the illustrated embodiment is that the first access network device sends a radio resource control release message including a suspension configuration to the terminal, and the RRCRelease message including the suspension configuration is used to save the context of the terminal and instruct the terminal to release the RRC connection. The terminal enters an inactive state.

[0279] S305. LMF sends a location request to the access network device where the terminal is registered in the radio access network notification area (RNA).

[0280] Correspondingly, the access network device where the terminal is registered receives the positioning request.

[0281] When the terminal is in an inactive state, if LMF needs to locate the terminal, LMF sends a location request to the access network device registered with the terminal in RNA through AMF. The location request is used to request terminal location.

[0282] S306. All access network devices in RNA send paging information to the terminal.

[0283] Correspondingly, the terminal receives the paging information.

[0284] Unlike when the terminal is in an idle state, when all access network devices in the TA need to send a paging message to the terminal, when the terminal is in an inactive state, all access network devices in the RNA send a paging message to the terminal. The RNA is a collection of access network devices in a region in the TA.

[0285] In this embodiment, the paging information is used to indicate the triggering state of the terminal. The paging information can be carried in the paging message, or carried in the scheduling information of the paging message, or carried in the scheduling information of the paging message and the paging message. For specific implementation, please refer to Figure 8 Step S205 of the illustrated embodiment.

[0286] S307. The terminal measures the downlink reference signal according to the configuration information of the downlink reference signal.

[0287] For specific implementation, please refer to Figure 8 Step S206 of the illustrated embodiment.

[0288] S308': The terminal sends a measurement result of a downlink reference signal, or first information, to the positioning device.

[0289] Correspondingly, the positioning device receives the measurement result of the downlink reference signal, or the first information, wherein the first information includes one or more of the following information: the actual number of times the uplink reference signal is sent, and the index information of the resident cell.

[0290] The positioning device can accurately obtain the measurement result of the uplink reference signal based on the actual number of times the uplink reference signal is transmitted, thereby improving the measurement accuracy of the uplink reference signal; the positioning device can roughly locate the terminal based on the index information of the resident cell obtained, thereby improving the efficiency of terminal positioning.

[0291] S308”: The terminal sends an uplink reference signal according to the configuration information of the uplink reference signal.

[0292] Correspondingly, the access network device receives the uplink reference signal. The access network device may be all access network devices in the RNA. All access network devices in the RNA may include the above-mentioned first access network device, or may not include the above-mentioned first access network device. In this example, it is described that all access network devices in the RNA may include the above-mentioned first access network device.

[0293] S309. The first access network device measures the uplink reference signal to obtain a measurement result of the uplink reference signal.

[0294] Similarly, other access network devices in RNA also measure the uplink reference signal to obtain the measurement result of the uplink reference signal.

[0295] S310. The first access network device sends a measurement result of an uplink reference signal to a positioning device.

[0296] Correspondingly, the positioning device receives the measurement result of the uplink reference signal.

[0297] S311. The positioning device positions the terminal according to the measurement result of the uplink reference signal or the measurement result of the downlink reference signal.

[0298] For specific implementation, please refer to Figure 8 Step S210 of the illustrated embodiment.

[0299] The measurement result of the downlink reference signal includes one or more of the following measurement quantities:

[0300] Downlink reference signal time difference, reference signal reception power of downlink positioning reference signal, terminal transmission and reception time difference, reference signal reception power of synchronization signal, reference signal reception quality of synchronization signal.

[0301] According to the terminal positioning method provided in the embodiment of the present application, the positioning device can trigger the terminal to send an uplink reference signal or measure a downlink reference signal through paging information at any time as needed. The terminal does not need to send or measure at the prescribed measurement sending time, and the measurement result of the uplink reference signal or the downlink reference signal can be sent when the terminal is in an idle state or an inactive state, thereby saving the power consumption of the terminal; and the positioning device supports positioning based on uplink and downlink, thereby improving the positioning accuracy.

[0302] like Fig.10 As shown, it is another flowchart of the terminal positioning method provided in the embodiment of the present application, and the method may include the following steps:

[0303] S401. The first access network device sends configuration information of an uplink reference signal to a positioning device through an AMF, or the first access network device sends configuration information of a downlink reference signal to a positioning device through an AMF.

[0304] Correspondingly, the positioning device receives the configuration information of the uplink reference signal or the configuration information of the downlink reference signal sent by the first access network device. The first access network device is an access network device serving the terminal.

[0305] In addition, the neighboring cell access network device (not shown in the figure) sends the configuration information of the downlink reference signal to the positioning device through the AMF, and the positioning device receives the configuration information of the downlink reference signal sent by the neighboring cell access network device.

[0306] For specific implementation, please refer to Figure 8 Step S201 in the illustrated embodiment, or Fig. 9 Step S301 of the illustrated embodiment will not be described in detail here.

[0307] S402. The positioning device sends configuration information of a downlink reference signal to the terminal through the AMF and the first access network device.

[0308] S403. The positioning device sends measurement request information to the terminal through the AMF and the first access network device.

[0309] Correspondingly, the terminal receives the measurement request information. The measurement request information is based on LPP. The measurement request information is used to request the terminal to perform positioning.

[0310] and Figure 8 , Fig. 9 The difference from the illustrated embodiment is that, in this embodiment, the measurement request information is used to instruct the terminal to perform one or more of the following operations after receiving the paging information:

[0311] Measurement of downlink reference signals;

[0312] Report the measurement result of the downlink reference signal.

[0313] This means that after receiving the measurement request information, the terminal may not perform the above operation immediately, but postpone the above operation and perform the above operation after receiving the paging information.

[0314] In addition, the positioning device also configures a trigger state set of paging information, which is included in the measurement request information. According to the paging information carried in the paging message, or the scheduling information of the paging message, or the paging message and the scheduling information of the paging message, the trigger state set has the following implementations:

[0315] In one implementation, the paging information is carried in a paging message, and the measurement request information includes a fifth trigger state set. The fifth trigger state set includes one or more fifth trigger states.

[0316] The fifth trigger state includes one or more of the following trigger states:

[0317] does not trigger; or

[0318] triggering measurement of one or more downlink reference signal sets; or

[0319] Stop measuring one or more downlink reference signal sets; or

[0320] Stop measuring all downlink reference signal sets; or

[0321] Trigger reporting of measurement results of one or more downlink reference signal sets.

[0322] Exemplarily, the format of the fifth trigger state set is as follows:

[0323]

[0324] It can be seen that for any triggering state, operations on one or more reference signal resource sets in DL-RS-SetId can be triggered.

[0325] Furthermore, the measurement request information may also include one or more of the following information: the number of downlink reference signal measurements, and the time interval between reporting the downlink reference signal measurement result and receiving the paging information.

[0326] In another implementation, the paging information is carried in the scheduling information of the paging message, and the measurement request information further includes a sixth trigger state set. The sixth trigger state set includes one or more sixth trigger states. The number of sixth trigger states included in the sixth trigger state set may be the same as or different from the number of fifth trigger states included in the fifth trigger state set; the format of the sixth trigger state set may be the same as or different from the format of the fifth trigger state set.

[0327] In another implementation, the paging information is carried in the scheduling information of the paging message and the paging message, and the measurement request information also includes a seventh trigger state set and an eighth trigger state set. The eighth trigger state set includes one or more eighth trigger states. The number of trigger states included in the eighth trigger state set may be the same as or different from the number of fifth trigger states included in the fifth trigger state set; the format of the eighth trigger state set may be the same as or different from the format of the fifth trigger state set.

[0328] The seventh trigger state set includes one or more seventh trigger states, and the seventh trigger state includes one or more of the following trigger states:

[0329] does not trigger; or

[0330] Determined according to an eighth trigger state; or

[0331] triggering measurement of one or more downlink reference signal sets; or

[0332] Stop measuring one or more downlink reference signal sets; or

[0333] Stop measuring all downlink reference signal sets; or

[0334] The trigger triggers reporting of measurement results of one or more downlink reference signal sets.

[0335] Exemplarily, the format of the seventh trigger state set is as follows:

[0336]

[0337]

[0338] The difference between this implementation and the above implementation is that the seventh trigger state set also includes a seventh trigger state: upToPCH, which means that the trigger state indicated by the scheduling information depends on the eighth trigger state. The eighth trigger state is the trigger state indicated by the paging message carried on the PCH included in the physical downlink shared channel scheduled by the scheduling information. That is, the trigger state is determined jointly according to the scheduling information of the paging message and the paging message.

[0339] S404: The first access network device sends a RRCRelease message including a suspension configuration to the terminal.

[0340] Correspondingly, the terminal receives the RRCRelease message including the suspension configuration.

[0341] The first access network device sends a radio resource control release message including the suspension configuration to the terminal, and the RRCRelease message including the suspension configuration is used to save the context of the terminal and instruct the terminal to release the RRC connection. The terminal enters an inactive state.

[0342] and Figure 8 , Fig. 9 The difference from the embodiment shown is that in this embodiment, the RRCRelease message including the suspension configuration includes the configuration information of the uplink reference signal, that is, the positioning device carries the configuration information of the uplink reference signal in the RRCRelease message including the suspension configuration.

[0343] In this embodiment, the radio resource control release message including the suspension configuration is used to instruct the terminal to perform one or more of the following operations after receiving the paging information:

[0344] Transmission of uplink reference signals;

[0345] Report the first information.

[0346] This means that after receiving the RRCRelease message including the suspension configuration, the terminal may not perform the above operation immediately, but postpone the execution of the above operation and perform the above operation after receiving the paging information.

[0347] The first information includes one or more of the following information: the actual number of times the uplink reference signal is sent, and the index information of the resident cell. The positioning device can accurately obtain the measurement result of the uplink reference signal based on the actual number of times the uplink reference signal is sent, thereby improving the measurement accuracy of the uplink reference signal; the positioning device can roughly locate the terminal based on the index information of the resident cell, thereby improving the efficiency of terminal positioning.

[0348] In addition, the positioning device also configures a trigger state set of paging information, which is included in the radio resource control release message containing the suspension configuration. According to the paging information carried in the paging message, or the scheduling information of the paging message, or the paging message and the scheduling information of the paging message, the trigger state set has the following implementations:

[0349] In one implementation, the paging information is carried in a paging message, and the measurement request information includes a ninth trigger state set. The ninth trigger state set includes one or more ninth trigger states.

[0350] The ninth trigger state includes one or more of the following trigger states:

[0351] does not trigger; or

[0352] triggering the transmission of one or more uplink reference signal sets; or

[0353] Stop sending one or more uplink reference signal sets; or

[0354] Stop sending all uplink reference signal sets; or

[0355] Triggering reporting of the first information.

[0356] Exemplarily, the format of the ninth trigger state set is as follows:

[0357]

[0358]

[0359] It can be seen that for any triggering state, operations on one or more reference signal resource sets in UL-RS-SetId can be triggered.

[0360] Furthermore, the radio resource control release message including the suspension configuration may also include: the number of times the uplink reference signal is sent. Accordingly, the terminal may also report the actual number of times the uplink reference signal is sent. In addition, the terminal may also report the index information of the resident cell, and the index information of the resident cell is used by the positioning device to perform approximate positioning.

[0361] Therefore, the above-mentioned first information includes one or more of the following information: the actual number of times the uplink reference signal is sent, and the index information of the resident cell.

[0362] In another implementation, the paging information is carried in the scheduling information of the paging message, and the radio resource control release message including the suspension configuration also includes a tenth trigger state set. The tenth trigger state set includes one or more tenth trigger states. The tenth trigger state included in the tenth trigger state set may be the same as the ninth trigger state of the ninth trigger state set.

[0363] In another implementation, the paging information is carried in the scheduling information of the paging message and the paging message, and the radio resource control release message including the suspension configuration also includes an eleventh trigger state set and a twelfth trigger state set. The twelfth trigger state set includes one or more twelfth trigger states. The trigger states included in the twelfth trigger state set may be the same as the ninth trigger state set.

[0364] The eleventh trigger state set includes one or more eleventh trigger states, and the eleventh trigger state includes one or more of the following trigger states:

[0365] does not trigger; or

[0366] Determined according to a twelfth trigger state; or

[0367] triggering the transmission of one or more uplink reference signal sets; or

[0368] Stop sending one or more uplink reference signal sets; or

[0369] Stop sending all uplink reference signal sets; or

[0370] Triggering reporting of the first information.

[0371] Exemplarily, the format of the eleventh trigger state set is as follows:

[0372]

[0373]

[0374] The difference between this implementation and the above implementation is that the eleventh trigger state set also includes an eleventh trigger state: upToPCH, which means that the trigger state indicated by the scheduling information depends on the twelfth trigger state. The twelfth trigger state is the trigger state indicated by the paging message carried on the PCH included in the physical downlink shared channel scheduled by the scheduling information. That is, the trigger state is determined jointly according to the scheduling information of the paging message and the paging message.

[0375] S405. LMF sends a positioning request to the access network device where the terminal is registered in RNA.

[0376] Correspondingly, the access network device where the terminal is registered receives the positioning request.

[0377] When the terminal is in an inactive state, if LMF needs to locate the terminal, LMF sends a location request to the access network device registered with the terminal in RNA through AMF. The location request is used to request terminal location.

[0378] S406. All access network devices in RNA send paging information to the terminal.

[0379] Correspondingly, the terminal receives the paging information.

[0380] Unlike when the terminal is in an idle state, when all access network devices in the TA need to send a paging message to the terminal, when the terminal is in an inactive state, all access network devices in the RNA send a paging message to the terminal. The RNA is a collection of access network devices in a region in the TA.

[0381] In this embodiment, the paging information is used to indicate the triggering state of the terminal. The paging information can be carried in the paging message, or carried in the scheduling information of the paging message, or carried in the scheduling information of the paging message and the paging message. For specific implementation, please refer to Figure 8 Step S205 of the illustrated embodiment, or Fig. 9 Step S306 of the illustrated embodiment.

[0382] S407: The terminal measures the downlink reference signal according to the configuration information of the downlink reference signal.

[0383] For specific implementation, please refer to Figure 8 Step S206 of the illustrated embodiment, or Fig. 9 Step S307 of the illustrated embodiment.

[0384] S408': The terminal sends a measurement result of a downlink reference signal, or first information, to the positioning device.

[0385] Correspondingly, the positioning device receives the measurement result of the downlink reference signal, or the first information.

[0386] The first information includes one or more of the following information: the actual number of times the uplink reference signal is sent, and the index information of the resident cell. The positioning device can accurately obtain the measurement result of the uplink reference signal based on the actual number of times the uplink reference signal is sent, thereby improving the measurement accuracy of the uplink reference signal; the positioning device can roughly locate the terminal based on the index information of the resident cell, thereby improving the efficiency of terminal positioning.

[0387] S408". The terminal sends an uplink reference signal according to the configuration information of the uplink reference signal.

[0388] Correspondingly, the access network device receives the uplink reference signal. The access network device may be all access network devices in the RNA. All access network devices in the RNA may include the above-mentioned first access network device, or may not include the above-mentioned first access network device. In this example, it is described that all access network devices in the RNA may include the above-mentioned first access network device.

[0389] S409: The access network device measures the uplink reference signal to obtain a measurement result of the uplink reference signal.

[0394] For specific implementation, please refer to Figure 8 Step S210 of the illustrated embodiment, or Fig. 9 Step S311 of the illustrated embodiment.

[0395] According to the terminal positioning method provided in the embodiment of the present application, the positioning device can trigger the terminal to send an uplink reference signal or measure a downlink reference signal through paging information at any time as needed.

The transceiver unit 1201, which may also be called a transceiver unit, is used to implement a transceiver function, for example, a transceiver circuit, a transceiver, a transceiver or a communication interface.

[0415] Wherein, taking the communication device 120 as the positioning device in the above method embodiment as an example, then:

[0416] The transceiver unit 1201 is configured to send paging information when the terminal is in an idle state or an inactive state, where the paging information is used to indicate a trigger state of the terminal, where the trigger state is used to instruct the terminal to send an uplink reference signal for positioning, or to instruct the terminal to measure a downlink reference signal for positioning;
