Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a positioning method and device / storage medium / apparatus. Background Technology

[0002] 3GPP introduced positioning technology for UEs (User Equipment) in RRC (Radio Resource Control) disconnected state (where RRC disconnected state includes RRC inactive state and / or RRC idle state). Furthermore, the positioning capabilities supported by a UE in RRC disconnected state are not necessarily the same as those supported in RRC connected state.

[0003] In related technologies, during the location process, the Location Management Function (LMF) cannot determine the RRC state of the UE. At this time, since the location capabilities supported by the UE in the RRC disconnected state and the RRC connected state are not necessarily the same, the location capabilities used by the LMF may not match the RRC state of the UE. For example, the LMF may use the location capabilities of the RRC connected state to locate the UE in the RRC disconnected state, which will result in the inability to locate the UE in the RRC disconnected state. Summary of the Invention

[0048] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0049] The positioning method and device / storage medium / apparatus provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0050] Figure 1a This is a flowchart illustrating a positioning method provided in an embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 1a As shown, the positioning method may include the following steps:

[0051] Step 101a: Perform positioning operation based on the UE's positioning capabilities, including whether the UE supports the ability to measure downlink positioning reference signals and / or whether it supports the ability to send uplink positioning reference signals.

[0052] It should be noted that, in one embodiment of this disclosure, the UE can be a device that provides voice and / or data connectivity to a user. The terminal device can communicate with one or more core networks via a RAN (Radio Access Network). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can also be a device from an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0053] In one embodiment of this disclosure, the RRC non-connected state may include the RRC inactive state and / or the RRC idle state.

[0054] Furthermore, in one embodiment of this disclosure, the UE's positioning capability can be determined after determining whether the UE in the RRC disconnected state needs to perform a positioning procedure. Specifically, after determining that the UE in the RRC disconnected state needs to perform a positioning procedure, it is necessary to determine the UE's positioning capability.

[0055] In one embodiment of this disclosure, it can be determined whether a UE in an RRC disconnected state needs to perform a location procedure by detecting an event. When an event is detected, it is considered that the UE needs to perform a location procedure; when no event is detected, it is considered that the UE does not need to perform a location procedure. In one embodiment of this disclosure, the event can be an event that triggers the UE to perform a location procedure. For example, in one embodiment of this disclosure, the event could be: the UE using an application that requires location (e.g., a map application or a navigation application). In another embodiment of this disclosure, the event could be: periodically reporting the UE's location information and / or location measurement results to the network-side device, where the current time point is the reporting time point when the UE's location information and / or location measurement results need to be reported.

[0056] Furthermore, in another embodiment of this disclosure, a UE in the RRC disconnected state can determine whether it needs to perform a positioning procedure by whether it receives a positioning-related message sent by the network-side device. When the UE receives a positioning-related message sent by the network-side device, it is considered that the UE needs to perform a positioning procedure. When the UE does not receive a positioning-related message sent by the network-side device, it is considered that the UE does not need to perform a positioning procedure.

[0057] In one embodiment of this disclosure, the positioning-related message may be an LPP (LTE Positioning Protocol) message.

[0058] Furthermore, in one embodiment of this disclosure, the aforementioned LPP message may include at least one of the following:

[0059] LPP provides assistance information messages;

[0060] LPP request location information message.

[0061] The UE's positioning capability information includes: whether the UE supports the ability to measure downlink positioning reference signals; and / or whether the UE supports the ability to transmit uplink positioning reference signals.

[0062] In one embodiment of this disclosure, the downlink positioning reference signal may be, for example, a PRS (Positioning reference signal), and the uplink positioning reference signal may include an SRS (Sounding Reference Signal).

[0063] Furthermore, in one embodiment of this disclosure, when the UE supports the ability to measure downlink positioning reference signals, the UE can receive downlink positioning reference signals sent by the network-side device and measure these downlink positioning reference signals to achieve UE positioning. In other words, when the UE supports measuring downlink positioning reference signals, it is determined that the UE supports downlink positioning capability. In another embodiment of this disclosure, when the UE supports sending uplink positioning reference signals, the UE can send uplink positioning reference signals to the network-side device, which will then measure these uplink positioning reference signals to achieve UE positioning. In other words, when the UE supports sending uplink positioning reference signals, it is determined that the UE supports uplink positioning capability. In yet another embodiment of this disclosure, when the UE supports both sending uplink positioning reference signals and measuring downlink positioning reference signals, it is determined that the UE supports both uplink and downlink positioning capabilities.

[0064] In one embodiment of this disclosure, different positioning operations can be performed based on the different positioning capabilities of the UE. The positioning operations will be described in detail in subsequent embodiments.

[0065] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0066] Figure 1b This is a flowchart illustrating a positioning method provided in another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 1b As shown, the positioning method may include the following steps:

[0067] Step 101b: The UE supports the ability to measure downlink positioning reference signals and / or transmit uplink positioning reference signals, and uses SDT (Small Data Transmission) to send an MO-LR (Mobile Originated Location Request) message to the network-side device.

[0068] In one embodiment of this disclosure, if the UE supports the ability to measure downlink positioning reference signals and / or transmit uplink positioning reference signals, then the UE is considered to support downlink positioning capability and / or uplink positioning capability. In this case, the UE can use SDT to send an MO-LR message to the network-side device to perform a positioning operation. Specifically, this positioning operation may include: obtaining a third positioning message sent by the network-side device. The positioning process triggered by this third positioning message matches the positioning capability supported by the UE in the RRC disconnected state, thereby allowing the UE in the RRC disconnected state to perform positioning based on the third positioning message. For example, if the network-side device instructs the UE to perform positioning through a downlink positioning operation, then the UE uses the downlink positioning operation for positioning. Similarly, if the network-side device instructs the UE to perform positioning through an uplink positioning operation, then the UE uses the uplink positioning operation for positioning. How the UE uses uplink and downlink positioning operations for positioning is a conventional positioning operation within the art.

[0069] Furthermore, in one embodiment of this disclosure, SDT may include CG-SDT (Configure Grant Small Data Transmission) and / or RA-SDT (Random Access Channel Small Data Transmission).

[0070] Furthermore, in one embodiment of this disclosure, the aforementioned network-side equipment may include an LMF and / or a base station. In one embodiment of this disclosure, the base station is configured to receive location-related information sent by the LMF and forward or transmit such information to the UE, and to receive location-related information sent by the UE and forward or transmit such information to the LMF, for example, the base station transmits LPP messages sent by the LMF to the UE, and the base station transmits LPP messages sent by the UE to the LMF.

[0071] Furthermore, it should be noted that in another embodiment of this disclosure, a UE in the RRC disconnected state can also use SDT to send an MT-LR (Mobile Terminated Location Request) message to the network-side device. When the UE supports the ability to measure downlink location reference signals and / or send uplink location reference signals, the UE can use SDT to send an MT-LR message to the network-side device.

[0072] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0073] Figure 2a This is a flowchart illustrating a positioning method provided in another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 2a As shown, the positioning method may include the following steps:

[0074] Step 201a: The UE does not support sending uplink positioning reference signals and does not support measuring downlink positioning reference signals, so it is determined that SDT will not be used to send MO-LR messages to the network-side equipment.

[0075] In one embodiment of this disclosure, when the UE does not support sending uplink positioning reference signals and does not support measuring downlink positioning reference signals (i.e., the UE does not support uplink positioning capability and does not support downlink positioning capability), it indicates that the UE cannot perform the positioning process in the disconnected state. In this case, it is determined that SDT will not be used to send MO-LR messages to the network-side device.

[0076] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0077] Figure 2b This is a flowchart illustrating a positioning method provided in yet another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 2b As shown, the positioning method may include the following steps:

[0078] Step 201b: The UE does not support sending uplink positioning reference signals and does not support measuring downlink positioning reference signals, and does not use SDT to send MO-LR messages to the network-side equipment.

[0079] Step 202b: The UE switches to RRC connected state and sends an MO-LR message to the network-side device.

[0080] Referring to the above content, when it is determined in step 201b that SDT is not used to send an MO-LR message to the network-side device, it indicates that the UE in the RRC disconnected state needs to perform a positioning procedure, but the UE in the RRC disconnected state cannot perform the positioning procedure. In this case, to ensure that the required positioning procedure can be performed successfully, after the UE in the RRC disconnected state transitions to the RRC connected state, it can send an MO-LR message to the network-side device to trigger a positioning operation. Specifically, this positioning operation may include: obtaining a fourth positioning message sent by the network-side device, and performing a positioning operation based on the fourth positioning message. This fourth positioning message is sent by the network-side device based on the positioning capabilities supported by the UE in the RRC connected state. For example, if the network-side device instructs the UE to perform positioning through a downlink positioning operation, the UE will use the downlink positioning operation. Similarly, if the network-side device instructs the UE to perform positioning through an uplink positioning operation, the UE will use the uplink positioning operation. How the UE uses uplink and downlink positioning operations for positioning is a conventional positioning operation within this field.

[0081] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0082] Figure 2c This is a flowchart illustrating a positioning method provided in another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 2c As shown, the positioning method may include the following steps:

[0083] Step 201c: The UE does not support the ability to measure downlink positioning reference signals, and / or does not support the ability to send uplink positioning reference signals. It requests the network-side device to switch to RRC connected state and perform positioning operation.

[0084] In one embodiment of this disclosure, the form of requesting the network-side device to switch to the RRC connection state may vary depending on the scenario.

[0085] Specifically, in one embodiment of this disclosure, when a UE in the RRC disconnected state receives an LPP message, since the LPP message is specifically used to trigger a downlink positioning procedure, it is necessary to first determine whether the UE in the RRC disconnected state supports measuring downlink positioning reference signals, that is, to determine whether the UE supports downlink positioning capability. If the UE does not support measuring downlink positioning reference signals, it means that the UE currently in the RRC disconnected state cannot execute the downlink positioning procedure triggered by the LPP message, and can then request the network-side device to switch to the RRC connected state to execute the downlink positioning procedure.

[0086] Furthermore, in one embodiment of this disclosure, the aforementioned LPP message may include at least one of the following:

[0087] LPP provides assistance information messages;

[0088] LPP request location information message.

[0089] Furthermore, in another embodiment of this disclosure, an event can be configured for the UE to trigger the positioning process. When the UE in the RRC disconnected state detects an event, it is determined whether the positioning capability of the UE in the disconnected state supports the execution of the event. If the execution of the event is not supported, a request can be made to the network-side device to switch to the RRC connected state.

[0090] For example, in one embodiment of this disclosure, the event could be: configuring the UE to periodically send uplink positioning reference signals. When the UE detects this "configuring the UE to periodically send uplink positioning reference signals" event, it can determine whether the UE currently supports sending uplink positioning reference signals. If the UE does not support sending uplink positioning reference signals, it can request a switch to RRC connected state from the network-side device to execute the event-triggered positioning operation. Specifically, this positioning operation can be: sending an MO-LR message to the network-side device and receiving a fourth positioning message sent by the network-side device based on the MO-LR message, and performing a positioning operation based on the fourth positioning message. The fourth positioning message is sent by the network-side device based on the positioning capabilities supported by the UE in RRC connected state. For example, if the network-side device instructs the UE to perform positioning through downlink positioning, the UE uses downlink positioning. Similarly, if the network-side device instructs the UE to perform positioning through uplink positioning, the UE uses uplink positioning. How the UE uses uplink and downlink positioning operations for positioning is a conventional positioning operation in the art.

[0091] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0092] Figure 3aThis is a flowchart illustrating a positioning method provided in yet another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 3a As shown, the positioning method may include the following steps:

[0093] Step 301a: The UE supports the ability to measure downlink positioning reference signals and send uplink positioning reference signals, does not request the network-side equipment to switch to RRC connection state, and performs positioning operations.

[0094] In one embodiment of this disclosure, if the UE supports the ability to measure downlink positioning reference signals and transmit uplink positioning reference signals, then the UE supports both downlink and uplink positioning capabilities in RRC disconnected mode. Therefore, it does not need to request a switch to RRC connected mode from the network side device and can perform positioning operations in RRC disconnected mode. Specifically, this positioning operation may include: sending an MO-LR message to the network side device and receiving a third positioning message sent by the network side device. The positioning process triggered by the third positioning message matches the positioning capabilities supported by the UE in RRC disconnected mode, thus allowing the UE in RRC disconnected mode to perform positioning based on the third positioning message.

[0095] It should be emphasized that, in one embodiment of this disclosure, the "UE's ability to measure downlink positioning reference signals and transmit uplink positioning reference signals" in step 301a can be obtained by inheriting the judgment result of determining the UE's positioning capability in step 101a above. In another embodiment of this disclosure, the "UE's ability to measure downlink positioning reference signals and transmit uplink positioning reference signals" in step 301a may not inherit the judgment result of determining the UE's positioning capability in step 101a above.

[0096] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0097] Figure 3bThis is a flowchart illustrating a positioning method provided in yet another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 3b As shown, the positioning method may include the following steps:

[0098] Step 301b: The UE supports the ability to send uplink positioning reference signals and uses SDT to send MO-LR messages to the network-side equipment.

[0099] Step 302b: Obtain the first location message sent by the network-side device.

[0100] In one embodiment of this disclosure, the first location message may be an LPP message.

[0101] Step 303b: In response to the UE not supporting the measurement of downlink positioning reference signals, request the network-side device to switch to RRC connected state and perform positioning operation.

[0102] In one embodiment of this disclosure, the first positioning message is specifically used to trigger a downlink positioning process. Based on this, when a UE in an RRC non-connected state receives the first positioning message, it is necessary to first determine whether the UE supports measuring downlink positioning reference signals (i.e., determine whether the UE supports downlink positioning capability) in order to determine whether the UE can successfully execute the downlink positioning process triggered by the first positioning message.

[0103] Furthermore, in one embodiment of this disclosure, when the UE does not support measuring downlink positioning reference signals (i.e., the UE does not support downlink positioning capability), it indicates that the UE in the disconnected state cannot execute the downlink positioning procedure triggered by the first positioning message. However, the UE in the RRC disconnected state needs to execute the positioning procedure. In this case, to ensure that the required positioning procedure can be executed successfully, the UE can request a switch to the RRC connected state from the network-side device, and then perform the positioning operation after switching to the RRC connected state. Specifically, this positioning operation may include: after switching to the RRC connected state, directly performing positioning based on the aforementioned first positioning message.

[0104] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0105] Figure 4 This is a flowchart illustrating a positioning method provided in yet another embodiment of the present disclosure, applied to a UE in an RRC disconnected state, such as... Figure 4 As shown, the positioning method may include the following steps:

[0106] Step 401: Send UE capability indication information to the network-side device. The UE capability indication information is used to indicate whether the UE supports the ability to measure downlink positioning reference signals and / or whether it supports the ability to send uplink positioning reference signals, and perform positioning operations.

[0107] In one embodiment of this disclosure, the method for the UE to send UE capability indication information to the network-side device may include at least one of the following:

[0108] UE capability indication information is sent to the network-side equipment via the MO-LR message sent by SDT;

[0109] UE capability indication information is sent to the network-side equipment via event report messages;

[0110] UE capability indication information is sent to the network-side equipment via supplementary services messages;

[0111] The UE capability indication information is sent to the network-side device through the location message embedded in the supplementary services message.

[0112] In one embodiment of this disclosure, when a UE sends UE capability indication information to a network-side device via an MO-LR message sent using SDT, the UE can include the UE capability indication information in an LPP PDU (Long Term Evolution Positioning Protocol Data Unit) carried in the MO-LR message and send it to the network-side device.

[0113] Furthermore, in one embodiment of this disclosure, the UE capability indication information may include at least one of the following:

[0114] The first indication information indicates that the UE does not have the ability to measure downlink positioning reference signals, that is, the first indication information indicates that the UE does not support downlink positioning capability;

[0115] The second indication information indicates that the UE does not have the ability to send uplink positioning reference signals, that is, the first indication information indicates that the UE does not support uplink positioning capability;

[0116] The third indication information indicates that the UE has the ability to send uplink positioning reference signals, that is, the first indication information indicates that the UE supports uplink positioning capability;

[0117] The fourth indication information indicates that the UE has the ability to measure downlink positioning reference signals, that is, the first indication information indicates that the UE supports downlink positioning capability.

[0118] Furthermore, in one embodiment of this disclosure, the aforementioned third indication information can also be used to indicate the type of uplink positioning reference signal that the UE supports transmitting, wherein the type of uplink positioning reference signal may include periodic uplink positioning reference signal and / or semi-persistent uplink positioning reference signal.

[0119] Therefore, in one embodiment of this disclosure, after the network-side device receives the UE capability indication information, it can determine the positioning capabilities supported by the UE based on the UE capability indication information, and perform a positioning operation based on the positioning capabilities supported by the UE. Specifically, the positioning operation may include the following steps:

[0120] Step a: Obtain the second location information sent by the network-side device. The second location information is determined by the network-side device based on the UE capability indication information. The location process triggered by the second location information matches the UE's location capability indicated by the UE capability indication information.

[0121] In one embodiment of this disclosure, when the UE capability indication information indicates that the UE has the capability to measure downlink positioning reference signals (i.e., the UE supports downlink positioning capability), the network-side device sends second positioning information related to downlink positioning technology to the UE; when the UE capability indication information indicates that the UE has the capability to send uplink positioning reference signals (i.e., the UE supports uplink positioning capability), the network-side device sends second positioning information related to uplink positioning technology to the UE; when the UE capability indication information indicates that the UE has the capability to measure downlink positioning reference signals and the capability to send uplink positioning reference signals (i.e., the UE supports both downlink and uplink positioning capabilities), the network-side device sends second positioning information related to downlink positioning technology, or second positioning information related to uplink positioning technology, or second positioning information related to a combined uplink and downlink positioning technology to the UE.

[0122] Step b: Perform positioning based on the second positioning information.

[0123] For example, if the network-side device instructs the UE to perform location operations via downlink positioning, then the UE will use downlink positioning operations for location. Conversely, if the network-side device instructs the UE to perform location operations via uplink positioning, then the UE will use uplink positioning operations for location. How the UE uses uplink and downlink positioning operations for location is a matter of customary positioning practices within this field.

[0124] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0125] Figure 5 This is a flowchart illustrating a positioning method provided in yet another embodiment of the present disclosure, applied to a network-side device, such as... Figure 5 As shown, the positioning method may include the following steps:

[0126] Step 501: Receive information sent by the UE in the RRC disconnected state.

[0127] In one embodiment of this disclosure, the information in step 501 may be an MO-LR message sent by a UE in RRC disconnected state via SDT. In another embodiment of this disclosure, the information in step 601 may be a request to switch to RRC connected state sent by a UE in RRC disconnected state. In yet another embodiment of this disclosure, the information in step 601 may be UE capability indication information sent by a UE in RRC disconnected state.

[0128] Furthermore, in one embodiment of this disclosure, the network-side device may include an LMF and a base station. In one embodiment of this disclosure, the base station is configured to receive information sent by the LMF and forward that information to the UE, and to receive information sent by the UE and forward that information to the LMF.

[0129] Step 502: Based on the received information, instruct the UE to perform a positioning operation that matches the UE's positioning capabilities.

[0130] In one embodiment of this disclosure, the network-side device can instruct the UE to perform a positioning operation that matches the UE's positioning capabilities based on different information. The positioning operation will be described in detail in subsequent embodiments.

[0131] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0134] Step 602: Instruct the UE to perform a positioning operation that matches the UE's positioning capabilities based on the MO-LR message.

[0135] In one embodiment of this disclosure, the positioning operation may specifically include: sending a third positioning message to a UE in a disconnected state, wherein the positioning process triggered by the third positioning message matches the positioning capabilities supported by the UE in the RRC disconnected state. For example, if the network-side device instructs the UE to perform positioning via downlink positioning, the UE will use downlink positioning. If the network-side device instructs the UE to perform positioning via uplink positioning, the UE will use uplink positioning. How the UE performs positioning via uplink or downlink positioning is a conventional positioning operation in the art.

[0136] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state. In other words, this disclosure provides a positioning method for locating a UE in an RRC-disconnected state, solving the problem that "the network-side device cannot determine the RRC state of the UE, resulting in the inability to successfully locate the UE in the RRC-disconnected state."

[0138] Step 701 receives a state switching request sent by a UE in the RRC disconnected state. The state switching request is used to request a switch to the RRC connected state.

[0139] Step 702: Instruct the UE to switch to RRC connected state and perform a positioning operation.

[0140] In one embodiment of this disclosure, the positioning operation may be as follows: based on the positioning capability of the UE in RRC connection state, a fourth positioning message is sent to the UE that has switched to RRC connection state, so that the UE in RRC connection state can perform positioning based on the fourth positioning message. For example, if the network-side device instructs the UE to perform positioning through downlink positioning operation, then the UE uses downlink positioning operation for positioning. If the network-side device instructs the UE to perform positioning through uplink positioning operation, then the UE uses uplink positioning operation for positioning. How the UE performs positioning through uplink and downlink positioning operations is a conventional positioning operation in the art.

[0141] In summary, in the positioning method provided in this disclosure, a UE in an RRC-disconnected state can perform positioning operations based on its positioning capabilities. These positioning capabilities include whether the UE supports measuring downlink positioning reference signals and / or whether it supports transmitting uplink positioning reference signals. Therefore, in this disclosure, when a UE in an RRC-disconnected state needs to perform a positioning process, it can perform corresponding positioning operations based on its positioning capabilities, enabling the network-side device to determine a suitable positioning technology for the UE in the RRC-disconnected state.
