[0003] In the related art, it is proposed to locate a terminal device in an RRC (Radio Resource Control) non-connected state. The network-side device configures an uplink positioning reference signal for the terminal device in the RRC non-connected state according to the positioning information request sent by the LMF (Location Management Function) device. However, when the uplink positioning reference signal is a non-periodic or semi-continuous signal, how to activate or deactivate the uplink positioning reference signal for the terminal device in the RRC non-connected state is a technical problem that needs to be solved urgently.

The network side device can be a base station (base transceiver station, BTS) in a global system for mobile communications (GSM) system or code division multiple access (CDMA), or a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolved NodeB (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network side device can be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network side device (gNodeB, gNB) in a future 5G network or a network side device in a future evolved PLMN network, etc., and the embodiment of the present disclosure is not limited.

[0064] In an embodiment of the present disclosure, a terminal device or a network side 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 memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, 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 browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present disclosure does not specifically limit the specific structure of the execution subject of the method provided by the embodiment of the present disclosure. As long as it is possible to communicate according to the method provided by the embodiment of the present disclosure by running a program that records the code of the method provided by the embodiment of the present disclosure, for example, the execution subject of the method provided by the embodiment of the present disclosure can be a terminal device or a network side device, or a functional module in the terminal device or the network side device that can call and execute a program.

[0065] See Figure 1 , which is a structural diagram of a possible communication system 10 applicable to the present disclosure.

[0066] like Figure 1As shown, the communication system 10 includes a terminal device 101, a network side device 102 and a location management function device 103, which are described below respectively:

[0067] 1. Terminal device (TD) 101: This is a device with wireless transceiver capabilities. This includes various wireless communication-capable handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem. Terminals can be deployed in various forms, including mobile stations (MS), terminals, user equipment (UE), and soft terminals. Terminals can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water (e.g., ships); or in the air (e.g., aircraft, balloons, and satellites). For example, mobile phones, tablet computers, computers with wireless transceiver functions, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0068] 2. (Wireless) network side equipment (Radio Access Network, (R)AN) 102: is a device that provides wireless communication functions for terminals, including but not limited to: the next generation base station (g nodeB, gNB) in 5G, evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved nodeB, or home nodeB, HNB), baseband unit (BBU), transmission point (TRP), transmitting point (TP), etc.

[0069] 3. Location management function device 103: also known as location management network element, is used to perform location management of the terminal device 101, for example, to determine the location information of the UE. Specifically, the location management function device in the fifth generation (5G) wireless communication system may be a LMF (location management function, LMF) device. The LMF device may determine the location information of the UE based on the request of a core network entity (such as an access and mobility management function (AMF)) and provide the location information of the UE to the AMF, thereby providing location services (LCS). In implementation, the AMF may allocate at least one LMF to the UE to provide positioning services to the UE. When the UE needs to obtain positioning information, it may request the location information from the LMF through the AMF. In future communications (such as 6G or other networks), the location management network element may still be an LMF network element, or have other names, which is not limited in this disclosure.

[0070] It should be noted that the functional devices involved in the embodiments of the present disclosure may also be referred to as network elements, functions, or functional entities. For example, the location management functional device may also be referred to as a location management function, a location management functional entity, or a location management network element. The names of the various functional devices are not limited in this disclosure. Those skilled in the art may replace the names of the above functional devices with other names while performing the same functions, which falls within the scope of protection of this disclosure.

[0071] It is understandable that the above functional devices can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0072] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0073] The positioning method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0074] See Figure 2 , Figure 2 This is a flowchart of a positioning method provided by an embodiment of the present disclosure.

[0075] like Figure 2 As shown, the method is applied to a network-side device and may include but is not limited to the following steps:

[0076] S1: Receive an instruction from the location management function LMF device to activate or deactivate an uplink positioning reference signal.

[0077] In uplink positioning technology, the network-side device configures an uplink positioning reference signal for the terminal device. When the uplink positioning reference signal is a non-periodic or semi-continuous signal, in order to locate the terminal device, it is also necessary to activate or deactivate the uplink positioning reference signal.

[0078] Specifically, when the terminal device is in an RRC connected state, the network-side device may enable the terminal device to activate or deactivate the uplink positioning reference signal by sending a medium access control MAC (MAC) message or a downlink control information DCI (DCI) message. Where the uplink positioning reference signal is a non-periodic signal, the network-side device may enable the terminal device to activate or deactivate the uplink positioning reference signal by sending a DCI message; where the uplink positioning reference signal is a semi-persistent signal, the network-side device may enable the terminal device to activate or deactivate the uplink positioning reference signal by sending a MAC message.

[0079] S2: According to the instruction to activate or deactivate the uplink positioning reference signal, an activation command or a deactivation command is sent to the terminal device in the radio resource control RRC non-connected state.

[0080] The RRC non-connected state specifically includes an RRC idle state (RRC idle) / RRC inactive state (RRC inactive).

[0081] In an embodiment of the present disclosure, a network side device receives an instruction to activate or deactivate an uplink positioning reference signal sent by an LMF device, and sends an activation command or a deactivation command to a terminal device in a non-connected state of a radio resource control RRC according to the instruction to activate or deactivate the uplink positioning reference signal.

[0082] Specifically, when the terminal device is in an RRC non-connected state, the network side device in the embodiment of the present disclosure can send an activation command or a deactivation command to the terminal device, so that the terminal device can activate or deactivate the uplink positioning reference signal to realize positioning of the terminal device.

[0083] By implementing the embodiments of the present disclosure, after the network side device receives the instruction to activate or deactivate the uplink positioning reference signal sent by the LMF device, the network side device sends an activation command or a deactivation command to the terminal device in the RRC non-connected state according to the instruction to activate or deactivate the uplink positioning reference signal, so that the terminal device in the RRC non-connected state can receive the activation command or deactivation command sent by the network side device to activate or deactivate the uplink positioning reference signal, thereby realizing positioning of the terminal device.

[0084] See Figure 3 , Figure 3 This is a flowchart of another positioning method provided by an embodiment of the present disclosure.

[0085] like Figure 3 As shown, the method is applied to a network-side device and may include but is not limited to the following steps:

[0086] S1A: Receives instructions from the location management function LMF device to activate or deactivate the uplink positioning reference signal.

[0087] Among them, S1A has the same or similar technical effects as S1 in the above embodiment. For the description of the specific implementation of S1A, please refer to the description of the specific implementation of S1 in the above embodiment, which will not be repeated here.

[0088] S2A: According to the instruction to activate or deactivate the uplink positioning reference signal, after triggering the terminal device to enter the RRC connection state, an activation command or a deactivation command is sent to the terminal device.

[0089] It is understandable that when the terminal device is in the RRC non-connected state, under normal circumstances, the network side device cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device.

[0090] Based on this, in an embodiment of the present disclosure, when the terminal device is in an RRC non-connected state, the network side device triggers the terminal device to enter an RRC connected state and sends an activation command or a deactivation command to the terminal device. At this time, the terminal device can receive the activation command or the deactivation command, thereby activating or deactivating the uplink positioning reference signal to locate the terminal device.

[0091] It is understood that, in the embodiments of the present disclosure, after the network-side device triggers the terminal device to enter the RRC connected state, the network-side device can activate or deactivate the uplink positioning reference signal for the terminal device by sending a MAC message or a DCI message. Specifically, if the uplink positioning reference signal is a non-periodic signal, the network-side device can activate or deactivate the uplink positioning reference signal for the terminal device by sending a DCI message; if the uplink positioning reference signal is a semi-persistent signal, the network-side device can activate or deactivate the uplink positioning reference signal for the terminal device by sending a MAC message.

[0092] In an exemplary embodiment, the embodiment of the present disclosure sends an activation command or a deactivation command to a terminal device in a radio resource control RRC non-connected state, and also includes: when there is no ongoing uplink SDT in the terminal device, the network side device triggers the terminal device to enter the RRC connected state, and then sends an activation command or a deactivation command to the terminal device.

[0093] Among them, when there is no ongoing uplink SDT in the terminal device, the network side device cannot directly send an activation or deactivation command to the terminal device. Therefore, the network side device needs to trigger the terminal device to enter the RRC connection state and then send an activation command or deactivation command to the terminal device. The specific method of sending the activation command or deactivation command can be found in the above-mentioned discussion on the method of sending the activation command or deactivation command to the terminal device after the network side device triggers the terminal device to enter the RRC connection state. It will not be repeated here.

[0094] In some embodiments, in the embodiments of the present disclosure, after the network side device triggers the terminal device to enter the RRC connected state, it sends an activation command or a deactivation command to the terminal device in the radio resource control RRC non-connected state, and controls the terminal device to be in the RRC non-connected state.

[0095] It can be understood that when the terminal device is in the RRC non-connected state, the power consumption of the terminal device can be reduced. In the embodiment of the present disclosure, after the network side device triggers the terminal device to enter the RRC connected state and sends an activation command or a deactivation command to the terminal device, the terminal device is controlled to be in the RRC non-connected state, which can reduce the power consumption of the terminal device and further save energy.

[0096] See Figure 4 , Figure 4 This is a flowchart of another positioning method provided by an embodiment of the present disclosure.

[0097] like Figure 4 As shown, the method is applied to a network-side device and may include but is not limited to the following steps:

[0098] S1B: Receives instructions from the location management function LMF device to activate or deactivate the uplink positioning reference signal.

[0099] Among them, S1B has the same or similar technical effects as S1 in the above embodiment. For the description of the specific implementation of S1B, please refer to the description of the specific implementation of S1 in the above embodiment, which will not be repeated here.

[0100] S2B: According to the instruction to activate or deactivate the uplink positioning reference signal, when the terminal device is in the process of transmitting uplink small data SDT, an activation command or a deactivation command is sent to the terminal device.

[0101] It is understandable that when a terminal device is in an RRC non-connected state, the network-side device generally cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device. However, when the terminal device is in an ongoing uplink SDT (small data transmission, SDT), the terminal device can generate uplink data. At this time, the network device can also directly send downlink data to the terminal device. For example, the terminal device can receive a MAC message or DCI message sent by the network-side device to the terminal device.

[0102] Based on this, when the uplink positioning reference signal is a non-periodic or semi-continuous signal, the network side device can directly send an activation or deactivation command to the RRC non-connected terminal device through a DCI or MAC message, so that the terminal device activates or deactivates the uplink positioning reference signal.

[0103] In an embodiment of the present disclosure, when there is an ongoing uplink SDT on the terminal device, an activation command or a deactivation command, such as a MAC message or a DCI message, is sent to the terminal device, so that the terminal device can activate or deactivate the uplink positioning reference signal to locate the terminal device. Moreover, when there is an ongoing uplink SDT on the terminal device, an activation command or a deactivation command is directly sent to the terminal device in the RRC non-connected state. There is no need for the network side device to send relevant instructions to the terminal device to enter the RRC connected state, and then send the activation command or the deactivation command after the terminal device is in the RRC connected state. This can further reduce the delay and achieve rapid activation or deactivation of the uplink positioning reference signal.

[0104] See Figure 5 , Figure 5 This is a flowchart of another positioning method provided by an embodiment of the present disclosure.

[0105] like Figure 5 As shown, the method is applied to a network-side device and may include but is not limited to the following steps:

[0106] S1C: Receives instructions from the location management function LMF device to activate or deactivate the uplink positioning reference signal.

[0107] Among them, S1C has the same or similar technical effects as S1 in the above embodiment. For the description of the specific implementation of S1C, please refer to the description of the specific implementation of S1 in the above embodiment, which will not be repeated here.

[0108] S2C: Send a paging message to the terminal device according to the instruction to activate or deactivate the uplink positioning reference signal, and send an activation command or deactivation command to the terminal device during the random access process of the terminal device.

[0109] It is understandable that when the terminal device is in the RRC non-connected state, under normal circumstances, the network side device cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device.

[0110] Based on this, in the disclosed embodiments, a paging message is sent to a terminal device, and during the terminal device's random access process, an activation or deactivation command is sent to the terminal device, causing the terminal device to activate or deactivate an uplink positioning reference signal to achieve positioning of the terminal device. During this process, there is no need to send the activation or deactivation command after the terminal device is in the RRC connected state, which can further reduce latency and achieve rapid activation or deactivation of the uplink positioning reference signal.

[0111] In an exemplary embodiment, in an embodiment of the present disclosure, during the random access process of a terminal device, the network side device may send an activation command or a deactivation command to the terminal device through MSG2 or MSG4 (random access message 2 / random access message 4), or the network side device may send an activation command or a deactivation command to the terminal device through MSGB (random access message B).

[0112] Among them, in the 2-step random access process, in the embodiment of the present disclosure, the network side device sends an activation command or a deactivation command to the terminal device through MSGB (random access message B); in the 4-step random access process, in the embodiment of the present disclosure, the network side device sends an activation command or a deactivation command to the terminal device through MSG2 or MSG4 (random access message 2 / random access message 4).

[0113] In an exemplary embodiment, sending an activation command or a deactivation command to a terminal device in a non-connected state of radio resource control RRC also includes: sending a paging message to the terminal device when there is no ongoing uplink SDT in the terminal device, and sending an activation command or a deactivation command to the terminal device during the random access process of the terminal device.

[0114] Among them, when there is no ongoing uplink SDT in the terminal device, the network-side device cannot directly send a command to activate or deactivate the uplink positioning reference signal to the terminal device, so a paging message is sent to the terminal device, and during the random access process of the terminal device, the network-side device sends an activation command or a deactivation command to the terminal device. The specific manner in which the network-side device sends an activation command or a deactivation command to the terminal device can be found in the above-mentioned discussion on the manner in which the network-side device sends a paging message to the terminal device and sends an activation command or a deactivation command to the terminal device during the random access process of the terminal device, which will not be repeated here.

[0115] In some embodiments, in the embodiments of the present disclosure, a network side device sends a paging message to a terminal device, and during the random access process of the terminal device, after sending an activation command or a deactivation command to the terminal device, the terminal device is controlled to be in an RRC non-connected state.

[0116] It can be understood that when the terminal device is in the RRC non-connected state, the power consumption of the terminal device can be reduced. In the embodiment of the present disclosure, the network side device sends a paging message to the terminal device. During the random access process of the terminal device, after sending an activation command or a deactivation command to the terminal device, the terminal device is controlled to be in the RRC non-connected state, which can reduce the power consumption of the terminal device and further save energy.

[0117] In some embodiments, before receiving an instruction to activate or deactivate an uplink positioning reference signal sent by an LMF device, it also includes: receiving an indication message sent by the LMF device; and configuring an uplink positioning reference signal for the terminal device according to the indication message, wherein the uplink positioning reference signal is a non-periodic or semi-continuous signal.

[0118] In an embodiment of the present disclosure, the LMF device sends an indication message to the network side device through a newly defined new radiopositioning protocol A (NRPPa) message. The indication message may be a positioning information request message, which indicates or requests the network side device to configure an uplink positioning reference signal for the terminal device. Exemplarily, the indication information is included in a positioning information request (POSITIONING INFORMATION REQUEST) message.

[0119] Among them, the uplink positioning reference signal configured by the network side device for the terminal device is a non-periodic or semi-continuous signal. Therefore, when positioning the terminal device, the uplink positioning reference signal is used, and the uplink positioning reference signal needs to be activated or deactivated. Afterwards, the embodiment of the present disclosure receives the instruction to activate or deactivate the uplink positioning reference signal sent by the LMF device.

[0120] In some embodiments, the indication message includes a preset duration; wherein the preset duration is the maximum time required for the network measurement equipment to successfully configure an uplink positioning reference signal for the terminal equipment.

[0121] The preset duration is included in a positioning information request (POSITIONING INFORMATION REQUEST) message.

[0122] In an embodiment of the present disclosure, the indication message sent by the LMF device includes a preset duration to limit the time required for the network side device to configure the uplink positioning reference signal for the terminal device. When the time used by the network side device to configure the uplink positioning reference signal for the terminal device exceeds the preset duration, corresponding operations can be performed to achieve certain functions.

[0123] In some embodiments, the network side device fails to successfully configure an uplink positioning reference signal for the terminal device within a preset time period and sends a first error indication message to the LMF device.

[0124] Among them, the network side device receives the indication message sent by the LMF device and configures the uplink positioning reference signal for the terminal device. The terminal device is in the RRC non-connected state. In the embodiment of the present disclosure, the network side device configures the uplink positioning reference signal for the terminal device through the RRC release message. When the terminal device is in the RRC connected state for a long time, the network side device may fail to successfully configure the uplink positioning reference signal for the terminal device. In this case, the network side device sends a first error indication message to the LMF device.

[0125] In an embodiment of the present disclosure, when the network side device fails to successfully configure an uplink positioning reference signal for the terminal device within a preset time period, a first error indication message is sent to the LMF device to inform the LMF device that the network side device has failed to successfully configure an uplink positioning reference signal for the terminal device, so that the LMF device can know the result that the network side device has failed to successfully configure the uplink positioning reference signal for the terminal device, or, when knowing the result, send some instructions to perform other operations to solve the problem that the network side device has failed to successfully configure the uplink positioning reference signal for the terminal device.

[0126] In some embodiments, the first error indication message includes a cause value; wherein the cause value is that the terminal device does not enter the RRC non-connected state within a preset time period.

[0127] The reason value is included in the positioning information failure (POSITIONING INFORMATION FAILURE) message.

[0128] See Figure 6 , Figure 6 A flowchart of another positioning method provided by an embodiment of the present disclosure.

[0129] like Figure 6 As shown, the positioning method is applied to the network side device and may include but is not limited to the following steps:

[0130] S11: Receive a positioning information request message sent by a location management function LMF device to instruct or request a network side device to configure an uplink positioning reference signal for a terminal device.

[0131] In an embodiment of the present disclosure, the LMF device sends a positioning information request (POSITIONING INFORMATION REQUEST) message to the network side device through the NRPPa message. The positioning information request message instructs or requests the network side device to configure an uplink positioning reference signal for the terminal device.

[0132] S12: According to the positioning information request message, an uplink positioning reference signal is configured for the terminal device. If the uplink positioning reference signal is not successfully configured for the terminal device within the preset time, a second error indication message is sent to the LMF device; wherein the uplink positioning reference signal is applied to the terminal device in the non-connected state of the radio resource control RRC.

[0133] In an embodiment of the present disclosure, after the network side device receives a positioning information request message sent by the LMF device to instruct or request the network side device to configure an uplink positioning reference signal for the terminal device, the network side device configures an uplink positioning reference signal for the terminal device.

[0134] Among them, the uplink positioning reference signal is applied to the terminal device in the RRC non-connected state. In the embodiment of the present disclosure, the network side device configures the uplink positioning reference signal for the terminal device through the RRC release message. When the terminal device is in the RRC connected state for a long time, the network side device may fail to successfully configure the uplink positioning reference signal for the terminal device. In this case, the network side device sends a second error indication message to the LMF device.

[0135] In an embodiment of the present disclosure, when the network side device fails to successfully configure an uplink positioning reference signal for the terminal device within a preset time period, a second error indication message is sent to the LMF device to inform the LMF device that the network side device has failed to successfully configure an uplink positioning reference signal for the terminal device, so that the LMF device can know the result that the network side device has failed to successfully configure the uplink positioning reference signal for the terminal device, or, when knowing the result, send some instructions to perform other operations to solve the problem that the network side device has failed to successfully configure the uplink positioning reference signal for the terminal device.

[0136] In some embodiments, the second error indication message includes a cause value; wherein the cause value is that the terminal device does not enter the RRC non-connected state within a preset time period.

[0137] The reason value is included in the positioning information failure (POSITIONING INFORMATION FAILURE) message.

[0138] See Figure 7 , Figure 7 A flowchart of another positioning method provided by an embodiment of the present disclosure.

[0139] like Figure 7 As shown, the positioning method is applied to the terminal device and may include but is not limited to the following steps:

[0140] S111: When the terminal device is in an RRC non-connected state, receive an activation command or a deactivation command sent by a network side device.

[0141] The RRC non-connected state specifically includes an RRC idle state (RRC idle) / RRC inactive state (RRC inactive).

[0142] In uplink positioning technology, the network-side device configures an uplink positioning reference signal for the terminal device. When the uplink positioning reference signal is a non-periodic or semi-continuous signal, in order to locate the terminal device, it is also necessary to activate or deactivate the uplink positioning reference signal.

[0143] Specifically, when the terminal device is in the RRC connected state, the network side device can activate or deactivate the uplink positioning reference signal of the terminal device by sending a MAC message or a DCI message. In particular, when the uplink positioning reference signal is a non-periodic signal, the network side device can activate or deactivate the uplink positioning reference signal of the terminal device by sending a DCI message; when the uplink positioning reference signal is a semi-persistent signal, the network side device can activate or deactivate the uplink positioning reference signal of the terminal device by sending a MAC message.

[0144] It is understood that when a terminal device is in an RRC non-connected state, the network-side device generally cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device. However, in the disclosed embodiment, the terminal device can receive an activation command or a deactivation command when in an RRC non-connected state.

[0145] S112: Activate or deactivate the uplink positioning reference signal according to the activation command or deactivation command.

[0146] In the embodiment of the present disclosure, when the terminal device is in an RRC non-connected state, it receives an activation command or a deactivation command sent by a network side device, so that the terminal device can activate or deactivate the uplink positioning reference signal according to the activation command or the deactivation command to realize positioning of the terminal device.

[0147] By implementing the embodiments of the present disclosure, when the terminal device is in an RRC non-connected state, an activation command or a deactivation command sent by a network side device is received; according to the activation command or the deactivation command, the uplink positioning reference signal is activated or deactivated, so that the terminal device in the RRC non-connected state can activate or deactivate the uplink positioning reference signal after receiving the activation command or the deactivation command sent by the network side device, so as to realize positioning of the terminal device.

[0148] See Figure 8 , Figure 8 This is a flowchart of another positioning method provided by an embodiment of the present disclosure.

[0149] like Figure 8 As shown, the method is applied to a terminal device and may include but is not limited to the following steps:

[0150] S111A: When the terminal device is in the RRC non-connected state, it receives an instruction sent by the network side device to trigger the terminal device to enter the RRC connected state. The terminal device enters the RRC connected state and receives an activation command or a deactivation command sent by the network side device.

[0151] It is understandable that when the terminal device is in the RRC non-connected state, under normal circumstances, the network side device cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device. Based on this, in an embodiment of the present disclosure, when the terminal device is in the RRC non-connected state, the terminal device receives an instruction sent by the network side device to trigger the terminal device to enter the RRC connected state, the terminal device enters the RRC connected state, and receives an activation command or deactivation command sent by the network side device. At this time, the terminal device can receive the activation command or deactivation command, thereby activating or deactivating the uplink positioning reference signal to locate the terminal device.

[0152] It is understandable that, in the embodiment of the present disclosure, after the terminal device receives an instruction from the network side device to trigger the terminal device to enter the RRC connected state, after entering the RRC connected state, the network side device can activate or deactivate the uplink positioning reference signal for the terminal device by sending a MAC message or a DCI message. Specifically, when the uplink positioning reference signal is a non-periodic signal, the terminal device receives the DCI message sent by the network side device to activate or deactivate the uplink positioning reference signal; when the uplink positioning reference signal is a semi-persistent signal, the terminal device receives the MAC message sent by the network side device to activate or deactivate the uplink positioning reference signal.

[0153] In an exemplary embodiment, the embodiment of the present disclosure sends an activation command or a deactivation command to the terminal device, and also includes: when there is no ongoing uplink SDT on the terminal device, the terminal device receives an instruction from the network side device to trigger the terminal device to enter the RRC connection state, enters the RRC connection state, and receives the activation command or deactivation command sent by the network side device.

[0154] S112A: Activate or deactivate the uplink positioning reference signal according to the activation command or deactivation command.

[0155] Among them, S112A has the same or similar technical effects as S112 in the above embodiment. For the description of the specific implementation of S112A, please refer to the description of the specific implementation of S112 in the above embodiment, and will not be repeated here.

[0156] See Figure 9 , Figure 9 This is a flowchart of another positioning method provided by an embodiment of the present disclosure.

[0157] like Figure 9 As shown, the method is applied to a terminal device and may include but is not limited to the following steps:

[0158] S111B: When the terminal device is in an RRC non-connected state and there is an ongoing uplink small data transmission SDT on the terminal device, an activation command or a deactivation command sent by a network side device is received.

[0159] It is understandable that when a terminal device is in an RRC non-connected state, the network device generally cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device. However, when the terminal device is in an ongoing uplink SDT, the terminal device can generate uplink data, and at this time, the network device can also directly send downlink data to the terminal device, for example: the terminal device can receive a MAC message or DCI message sent by the network device.

[0160] Based on this, the terminal device can receive the DCI message or MAC message sent by the network side device to activate or deactivate the uplink positioning reference signal.

[0161] In an embodiment of the present disclosure, when there is an ongoing uplink SDT on the terminal device, the terminal device receives an activation command or a deactivation command, such as a MAC message or a DCI message, sent by a network side device, so that the terminal device can activate or deactivate an uplink positioning reference signal to locate the terminal device. Moreover, when there is an ongoing uplink SDT on the terminal device, the terminal device directly receives the activation command or the deactivation command sent by the network side device when the terminal device is in an RRC non-connected state. There is no need to switch to the RRC connected state and then activate or deactivate the uplink positioning reference signal after receiving the relevant instructions sent by the network side device to trigger the terminal device to enter the RRC connected state. This can further reduce the delay and achieve rapid activation or deactivation of the uplink positioning reference signal.

[0162] S112B: Activate or deactivate the uplink positioning reference signal according to the activation command or deactivation command.

[0163] Among them, S112B has the same or similar technical effects as S112 in the above embodiment. For the description of the specific implementation of S112B, please refer to the description of the specific implementation of S112 in the above embodiment, and will not be repeated here.

[0164] See Figure 10 , Figure 10 This is a flowchart of another positioning method provided by an embodiment of the present disclosure.

[0165] like Figure 10 As shown, the method is applied to a terminal device and may include but is not limited to the following steps:

[0166] S111C: When the terminal device is in the RRC non-connected state, it receives a paging message sent by the network side device, and receives an activation command or a deactivation command sent by the network side device during the random access process.

[0167] It is understandable that when the terminal device is in the RRC non-connected state, under normal circumstances, the network side device cannot directly send an uplink positioning reference signal activation or deactivation command to the terminal device.

[0168] Based on this, in an embodiment of the present disclosure, a paging message is received from a network side device, and during a random access process, the terminal device receives an activation command or a deactivation command sent by the network side device, and activates or deactivates the uplink positioning reference signal to locate the terminal device. During this process, there is no need to send an activation command or a deactivation command after the terminal device is in an RRC connection state, which can further reduce the delay and achieve rapid activation or deactivation of the uplink positioning reference signal.

[0169] In an exemplary embodiment, in an embodiment of the present disclosure, during the random access process of the terminal device, it can receive an activation command or a deactivation command sent by the network side device through MSG2 or MSG4 (random access message 2 / random access message 4), or it can receive an activation command or a deactivation command sent by the network side device through MSGB (random access message B).

[0170] Among them, in the 2-step random access process, in the embodiment of the present disclosure, the terminal device can receive the activation command or deactivation command sent by the network side device through MSGB (random access message B); in the 4-step random access process, in the embodiment of the present disclosure, the terminal device can receive the activation command or deactivation command sent by the network side device through MSG2 or MSG4 (random access message 2 / random access message 4).

[0171] In an exemplary embodiment, sending an activation or deactivation command to a terminal device also includes: when the terminal device does not have an ongoing uplink SDT, receiving a paging message sent by a network side device, and receiving an activation command or deactivation command sent by the network side device during a random access process.

[0172] Among them, when there is no ongoing uplink SDT in the terminal device, the terminal device receives the paging message sent by the network side device, and the specific method of receiving the activation command or deactivation command sent by the network side device during the random access process can be found in the above-mentioned terminal device receiving the paging message sent by the network side device, and receiving the activation command or deactivation command sent by the network side device during the random access process. The relevant discussion will not be repeated here.

[0173] S112C: Activate or deactivate the uplink positioning reference signal according to the activation command or deactivation command.

[0174] Among them, S112C has the same or similar technical effects as S112 in the above embodiment. For the description of the specific implementation of S112C, please refer to the description of the specific implementation of S112 in the above embodiment, and will not be repeated here.

[0175] In some embodiments, the positioning method provided in the embodiments of the present disclosure further includes: receiving a positioning capability request message sent by the LMF device; wherein the positioning capability request message is used to at least request to obtain the type and / or mobility status of the terminal device.

[0176] It can be understood that the uplink positioning reference signal of the terminal device is specific, and is an uplink positioning reference signal configured for the terminal device for the service cell where the terminal device is located. For example, the network side device can use the RRC release message to configure the terminal device with an uplink positioning reference signal for when the terminal device is in an RRC non-connected state. However, due to the movement of the terminal device, for example, the terminal device moves beyond the range of the service cell. At this time, the uplink positioning reference signal configured for the terminal device may be invalid. At this time, the network side device cannot locate the terminal device by using the uplink positioning reference signal configured for the terminal device, that is, it is not suitable to use the uplink positioning method to locate such terminal devices with a faster moving speed.

[0177] In addition, the type of terminal device can also reflect the mobility status of the terminal. For example, a certain type of terminal device, such as an IIoT (industrial internet of things) terminal device, has a low mobility speed and a limited mobility range. If the network side device configures it with an uplink positioning reference signal for the RRC non-connected state, the uplink positioning reference signal will usually not fail. Therefore, the uplink positioning method is also applicable to this type of terminal device when it is in the RRC non-connected state.

[0178] It should be noted that the positioning method of using the RRC release message to configure the uplink positioning reference signal for the terminal device can also be related to other conditions of the terminal device and can be set as needed. This disclosure does not impose any specific restrictions on this.

[0179] Based on this, in the embodiment of the present disclosure, the terminal device receives the positioning capability request information sent by the LMF device, and at least requests to obtain the type and mobility status of the terminal device to obtain the type and / or mobility status of the terminal device.

[0180] The positioning capability request message is an LPP request capabilities (Request Capabilities) message.

[0181] In some embodiments, the terminal device sends the type and / or mobility status of the terminal device to the LMF device according to the positioning capability request message.

[0182] In the embodiment of the present disclosure, after receiving the positioning capability request message sent by the LMF device, the terminal device sends the type and / or mobility status of the terminal device to the LMF device according to the positioning capability request message, so that it can be determined whether the uplink positioning method is applicable to the terminal device when it is in the RRC non-connected state. If the uplink positioning method is applicable, the method is used to locate the terminal device, so as to improve the accuracy of positioning the terminal device.

[0183] In the embodiment of the present disclosure, the type and / or mobility status of the terminal device sent by the terminal device to the LMF device is included in the LPP Provide Capabilities message.

[0184] In the embodiments provided above, the methods provided in the embodiments of the present disclosure are described from the perspectives of network-side devices and terminal devices, respectively. To implement the various functions of the methods provided in the embodiments of the present disclosure, the network-side devices and terminal devices may include hardware structures and software modules, and implement the aforementioned functions in the form of hardware structures, software modules, or hardware structures and software modules.
