[0100] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0101] The positioning measurement method, communication device, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings.
[0102] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method of this application embodiment can be applied to terminal devices. For example... Figure 2 As shown, the method may include, but is not limited to, the following steps: Step S201: Based on the SRS resource configuration of the terminal device in the inactive state configured by the serving network device for positioning measurement based on the probe reference signal (SRS), an uplink SRS signal is sent to enable the serving network device and adjacent serving network devices to perform SRS-based positioning measurement.
[0103] Optionally, the SRS resource configuration is configured by the serving network device. That is, the serving network device can configure the SRS resource configuration for the terminal device's positioning measurement based on the probe reference signal (SRS) in the inactive state, so that the terminal device can send uplink SRS signals according to the SRS resource configuration configured by the serving network device.
[0104] In one implementation, the SRS resource configuration is provided by the serving network device to the terminal device via a Radio Resource Control (RRC) connection release message while the terminal device is in a connected state. In other words, while the terminal device is in a connected state, the serving network device can configure the SRS resource information to the terminal device via an RRC connection release message before the RRC connection is released. This allows the terminal device to send uplink SRS signals based on the configured SRS resource information, enabling the serving network device and neighboring serving network devices to perform SRS-based positioning measurements.
[0105] In another implementation, the SRS resource configuration is configured by the serving network device and sent to the Location Management Unit (LMF), which then sends it to the terminal device. For example, when the terminal device is inactive, the serving network device can send the SRS resource configuration to the terminal device through the LMF, so that the terminal device can send an uplink SRS signal according to the SRS resource configuration, thereby enabling the serving network device and neighboring serving network devices to perform SRS-based positioning measurements.
[0106] By implementing this embodiment, the terminal device can send an uplink SRS signal according to the SRS resource configuration of the terminal device in the inactive state based on the probe reference signal (SRS) for positioning measurement, as configured by the serving network device. This enables the serving network device and neighboring serving network devices to perform SRS-based positioning measurements, allowing cellular network positioning technology to support the terminal device in performing uplink positioning measurements in the inactive state, thereby improving the efficiency and performance of cellular network positioning measurements.
[0107] Please see Figure 3 , Figure 3 This is a schematic flowchart illustrating another positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method in this embodiment can be applied to terminal devices. Figure 3 As shown, the method may include, but is not limited to, the following steps: Step S301: Receive a positioning capability request message sent by the location management unit (LMF).
[0108] Step S302: In response to the positioning capability request message, a positioning capability feedback message is sent to the positioning server. The positioning capability feedback message contains positioning measurement capability information supported by the terminal device and status indication information of the terminal device.
[0109] Optionally, when the terminal device receives the positioning capability request message sent by the LMF, it can reply to the positioning server with the supported positioning measurement capabilities through a positioning capability feedback message. The positioning capability feedback message contains the terminal device's status indication information, which can be understood as the current state of the terminal device, such as Idle state, inactive state, or Connected state.
[0110] Step S303: According to the SRS resource configuration of the terminal device in the inactive state configured by the serving network device for positioning measurement based on the probe reference signal (SRS), an uplink SRS signal is sent so that the serving network device and the adjacent serving network devices can perform SRS-based positioning measurement.
[0111] In the embodiments of this application, step S303 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0112] It should be noted that the actual execution order of steps S301, S302, and S303 does not necessarily have to follow the order described above. In other words, the steps described in steps S301, S302, and S303 are for the convenience of those skilled in the art and for ease of description, and the actual execution order does not necessarily have to follow the order described above.
[0113] By implementing this embodiment, when the terminal device responds to the positioning server with the supported positioning measurement capabilities, it carries the terminal device's status indication information in the positioning capability feedback message, thereby enabling the positioning server to understand the current status of the terminal device.
[0114] To avoid resource waste, the terminal device can send an uplink SRS signal according to the configured SRS resource settings after receiving the SRS activation request command. Optionally, Figure 4 This is a schematic flowchart illustrating a positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method of this application embodiment can be applied to terminal devices. For example... Figure 4 As shown, the method may include, but is not limited to, the following steps: Step S401: Receive a positioning capability request message sent by the location management unit (LMF).
[0115] In the embodiments of this application, step S401 can be implemented in any of the ways described in the various embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0116] Step S402: In response to the positioning capability request message, a positioning capability feedback message is sent to the positioning server. The positioning capability feedback message contains positioning measurement capability information supported by the terminal device and status indication information of the terminal device.
[0117] In the embodiments of this application, step S402 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0118] Step S403: In the inactive state, receive the activation request command sent by SRS.
[0119] It should be noted that, in one implementation, the SRS transmission activation request command refers to activating the UE's SRS signal transmission function, used to trigger the UE to send an uplink SRS signal. The SRS transmission activation request command can be implemented in several ways. For example, it can be sent to the terminal device via the Location Management Unit (LMF), or it can be sent to the serving network device via the LMF using an SRS-based positioning measurement request, so that the serving network device carries the SRS transmission activation request command in a paging message. Examples of these two methods are described below: As an example, the system receives an SRS transmission activation request command sent by the Location Management Unit (LMF). In other words, the LMF sends an SRS transmission activation request command to the terminal device, enabling the terminal device to send uplink SRS signals according to the configured SRS resources after receiving the command, thus avoiding resource waste.
[0120] As another example, the service network device receives a first paging message, which carries an SRS transmission activation request command. This first paging message is sent by the service network device after receiving an SRS-based positioning measurement request from the location management unit (LMF). In other words, the LMF sends an SRS-based positioning measurement request to the service network device, and the service network device carries an SRS transmission activation request command in the paging message. This ensures that the terminal device, upon receiving the paging message, sends an uplink SRS signal according to the configured SRS resources, thus avoiding resource waste.
[0121] Step S404: In response to the received SRS activation request command, according to the SRS resource configuration of the terminal device in the inactive state based on the probe reference signal SRS, the uplink SRS signal is sent so that the serving network device and the adjacent serving network devices can perform SRS-based positioning measurement.
[0122] Optionally, after receiving the SRS activation request command, the uplink SRS signal is sent according to the SRS resource configuration of the terminal device in the inactive state based on the Probe Reference Signal (SRS) for positioning measurement. The Location Management Unit (LMF) sends SRS-based positioning measurement requests and SRS resource configuration information to the serving network device station and neighboring network devices. The serving network device and neighboring serving network devices perform SRS-based positioning measurements according to the SRS resource configuration information and report the measurement results to the positioning server. Therefore, the embodiments of this application enable cellular network positioning technology to support terminal devices performing uplink positioning measurements in the inactive state, thereby improving the efficiency and performance of cellular network positioning measurements and avoiding resource waste.
[0123] In some embodiments of this application, the terminal device may also receive an SRS deactivation request command and, in response to the received SRS deactivation request command, stop sending uplink SRS signals. For example, after completing a measurement, if the terminal device receives an SRS deactivation request command, it can stop sending uplink SRS signals, thereby avoiding resource waste.
[0124] It should be noted that, in the embodiments of this application, the SRS can send a deactivation request command in several ways. For example, it can be sent to the terminal device through the location management unit, or it can be sent to the serving network device through the location management unit, and the serving network device can send the deactivation request command by carrying the SRS in the paging message. Examples of these two implementation methods are given below: As an example of a possible implementation, receiving the SRS deactivation request command includes receiving an SRS deactivation request command sent by the Location Management Unit (LMF). That is, the LMF sends a deactivation request command to the terminal device, causing the terminal device to stop sending uplink SRS signals upon receiving the command, thus avoiding resource waste.
[0125] As an example of a possible implementation, receiving the SRS deactivation request command includes: receiving a second paging message sent by the serving network device, the second paging message carrying the SRS deactivation request command; wherein, the second paging message is sent by the serving network device after receiving a stop measurement command sent by the location management unit (LMF). That is, the location management unit (LMF) sends a stop measurement command to the serving network device, and the serving network device carries the deactivation request command in the paging message, so that the terminal device stops sending uplink SRS signals after receiving the deactivation request command, thus avoiding resource waste.
[0126] It should be noted that the actual execution order of steps S401, S402, S403, and S404 does not necessarily have to follow the order described above. In other words, the steps described in S401, S402, S403, and S404 are for the convenience of those skilled in the art and for ease of description, and the actual execution order does not necessarily have to follow the order described above.
[0127] It is understood that the above embodiments describe the implementation of the positioning measurement method of this disclosure from the perspective of the terminal device. This disclosure also proposes another positioning measurement method, the implementation of which will be described below from the perspective of the location management unit (LMF). Please refer to... Figure 5 , Figure 5 This is a flowchart of another positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method in this embodiment can be applied to a location management unit (LMF). Figure 5 As shown, this positioning and measurement method may include, but is not limited to, the following steps: Step S501: Receive the Probe Reference Signal (SRS) resource configuration sent by the serving network device; wherein, the SRS resource configuration is the configuration information of the terminal device based on SRS for positioning measurement in the inactive state, configured by the serving network device.
[0128] Step S502: Send the SRS resource configuration to the terminal device so that the terminal device can send the uplink SRS signal in the inactive state according to the SRS resource configuration.
[0129] It is understood that the SRS resource configuration is configured by the serving network device. In other words, the serving network device can configure the SRS resource configuration for the terminal device's positioning measurement based on the probe reference signal (SRS) in the inactive state, so that the terminal device can send uplink SRS signals according to the SRS resource configuration configured by the serving network device.
[0130] In this embodiment, the SRS resource configuration configured by the serving network device can be transmitted to the terminal device via a transparent transmission method by the location management unit (LMF). For example, when the terminal device is in an inactive state, the serving network device can transmit the SRS resource configuration to the terminal device via the LMF in a transparent transmission method, so that the terminal device can send an uplink SRS signal according to the SRS resource configuration, thereby enabling the serving network device and neighboring serving network devices to perform SRS-based positioning measurements.
[0131] By implementing this embodiment, the Location Management Unit (LMF) can send the SRS resource configuration configured by the serving network device to the terminal device, enabling the terminal device to send uplink SRS signals in the inactive state according to the SRS resource configuration. This allows cellular network positioning technology to support the terminal device in performing uplink positioning measurements in the inactive state, thereby improving the efficiency and performance of cellular network positioning measurements.
[0132] Please see Figure 6 , Figure 6 This is a flowchart illustrating another positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method in this embodiment can be applied to a location management unit (LMF). Figure 6 As shown, this positioning and measurement method may include, but is not limited to, the following steps: Step S601: Send a location capability request message to the terminal device.
[0133] Step S602: Receive a positioning capability feedback message sent by the terminal device. The positioning capability feedback message contains positioning measurement capability information supported by the terminal device and status indication information of the terminal device.
[0134] Optionally, when the terminal device receives a positioning capability request message from the Location Management Unit (LMF), it can feed back its supported positioning capabilities to the positioning server. For example, the terminal device can return a positioning capability feedback message, which includes positioning measurement capability information supported by the terminal device and status indication information of the terminal device. This status indication information can be understood as the current state of the terminal device, such as Idle state, inactive state, or Connected state. When the LMF under the positioning server learns that the terminal device is inactive, it can also send an activation request command to the terminal device so that the terminal device can send uplink SRS signals according to the SRS resource configuration of the serving network device to achieve positioning measurement.
[0135] Step S603: Receive the Probe Reference Signal (SRS) resource configuration sent by the serving network device; wherein, the SRS resource configuration is the configuration information of the terminal device based on SRS positioning measurement in the inactive state configured by the serving network device.
[0136] Step S604: Send the SRS resource configuration to the terminal device.
[0137] Step S605: Send an activation request command to the terminal device, wherein the activation request command is used to instruct the terminal device to send an uplink SRS signal according to the SRS resource configuration.
[0138] It should be noted that there are several ways to send an activation request command. For example, the Location Management Unit (LMF) can send it directly to the terminal device. Alternatively, the LMF can send a location measurement request based on the Service Network Message Service (SRS) to the serving network device, so that the serving network device can carry the activation request command in a paging message. Examples of these two methods are described below: As an example, the location management unit (LMF) sends an SRS activation request command. That is, the LMF sends an SRS activation request command to the terminal device, so that upon receiving the command, the terminal device sends an uplink SRS signal according to the configured SRS resources, thus avoiding resource waste.
[0139] As another example, the Location Management Unit (LMF) sends a SRS-based positioning measurement request to the serving network device. Upon receiving the SRS positioning measurement request, the serving network device sends a first paging message to the terminal device, which carries an SRS activation request command. In other words, the LMF sends an SRS-based positioning measurement request to the serving network device, and the serving network device carries an SRS activation request command in the paging message. This enables the terminal device to send an uplink SRS signal according to the configured SRS resource settings after receiving the paging message, thus avoiding resource waste.
[0140] Step S606: Send an SRS-based location measurement request to the serving network device, and send an SRS-based location measurement request and SRS resource configuration to the neighboring network devices.
[0141] Optionally, the location management unit sends SRS-based location measurement requests and SRS resource configurations to the serving network device and neighboring network devices, enabling the serving network device and neighboring network devices to perform SRS-based location measurements. This allows cellular network positioning technology to support uplink positioning measurements performed by terminal devices in inactive mode, thereby improving the efficiency and performance of cellular network positioning measurements.
[0142] In some embodiments of this application, after the measurement is completed, the location management unit may also send a deactivation request command to the terminal device. The deactivation request command is used to instruct the terminal device to stop sending uplink SRS signals, which can avoid wasting resources.
[0143] It should be noted that there are several ways to send the deactivation request command. For example, the Location Management Unit (LMF) can directly send the deactivation request command to the terminal device. Alternatively, the LMF can send a stop measurement command to the serving network device, so that the serving network device can carry the deactivation request command in a paging message. Examples of these two methods are given below: As an example, the Location Management Unit (LMF) directly sends a deactivation request command to the terminal device. That is, the LMF sends an SRS deactivation request command to the terminal device, causing the terminal device to stop sending uplink SRS signals upon receiving the SRS activation request command, thus avoiding resource waste.
[0144] As another example, the Location Management Unit (LMF) sends a stop measurement command to the serving network device, causing the serving network device to send a second paging message to the terminal device after receiving the SRS positioning measurement request. This second paging message carries a deactivation request command. In other words, the LMF sends an SRS-based positioning measurement request to the serving network device, which then sends an activation request command via the SRS carried in the paging message. This causes the terminal device to stop sending uplink SRS signals upon receiving the paging message, thus avoiding resource waste.
[0145] In some embodiments of this application, the location management unit may also send a stop location measurement request message to the serving network device and neighboring serving network devices. That is, after the measurement is completed, the serving network device and neighboring serving network devices can be stopped from performing location measurement by sending a stop location measurement request message, thus avoiding resource waste.
[0146] It should be noted that the actual execution order of steps S601, S602, S603, S604, S605, and S606 does not necessarily have to follow the exact order described above. In other words, the steps described in S601, S602, S603, S604, S605, and S606 are for ease of understanding and description by those skilled in the art, and the actual execution order does not necessarily have to follow the exact order described above.
[0147] It is understood that the above embodiments describe the implementation of the positioning measurement method of this application from the perspective of a terminal device and a location management unit (LMF). This application also proposes another positioning measurement method, the implementation of which will be described below from the perspective of a serving network device. Please refer to... Figure 7 , Figure 7 This is a flowchart of another positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method in this embodiment can be applied to serving network devices. For example... Figure 7 As shown, this positioning and measurement method may include, but is not limited to, the following steps: Step S701: Configure the SRS resource configuration for positioning measurement based on the probe reference signal (SRS) in the inactive state of the terminal device.
[0148] In the embodiments of this application, step S701 can be implemented in any of the ways described in the various embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0149] Step S702: Send the configured SRS resource configuration to the location management unit (LMF) so that the LMF sends the SRS resource configuration to the terminal device, and the terminal device sends the uplink SRS signal according to the SRS resource configuration.
[0150] In one possible implementation, while the terminal device is in a connected state, the serving network device can also configure the SRS resource configuration to the terminal device via an RRC release message.
[0151] Step S703: Perform SRS-based positioning measurements.
[0152] By implementing this embodiment, by configuring the SRS resource configuration for SRS-based positioning measurement of the terminal device in the inactive state, and sending the configured SRS resource configuration to the terminal device through the location management unit (LMF) in a transparent manner, the cellular network positioning technology can support the terminal device to perform uplink positioning measurement in the inactive state, thereby improving the efficiency and performance of cellular network positioning measurement.
[0153] Please see Figure 8 . Figure 8 This is a flowchart of another positioning measurement method provided in an embodiment of this application. It should be noted that the positioning measurement method in this embodiment can be applied to serving network devices. Figure 8 As shown, the method may include, but is not limited to, the following steps: Step S801: Configure the SRS resource configuration for positioning measurement based on the probe reference signal (SRS) in the inactive state of the terminal device.
[0154] Step S802: Send the configured SRS resource configuration to the location management unit (LMF) so that the LMF sends the SRS resource configuration to the terminal device, and the terminal device sends the uplink SRS signal according to the SRS resource configuration.
[0155] Step S803: Receive a positioning measurement request based on SRS sent by the location management unit LMF.
[0156] Step S804: In response to the received SRS-based positioning measurement request, a first paging message is sent to the terminal device, the first paging message carrying an activation request command; wherein, the activation request command is used to instruct the terminal device to send an uplink SRS signal according to the SRS resource configuration.
[0157] Step S805: In response to the received SRS-based positioning measurement request, perform SRS-based positioning measurement according to the SRS resource configuration, and report the measurement results to the positioning server.
[0158] In some embodiments of this application, after completing the measurement, the serving network device can also receive a stop measurement command sent by the location management unit (LMF), and in response to the received stop measurement command, send a second paging message to the terminal device. The second paging message carries a deactivation request command; wherein, the deactivation request command is used to instruct the terminal device to stop sending uplink SRS signals. Therefore, by carrying a deactivation request command in the paging message, the terminal device stops sending uplink SRS signals after receiving the deactivation request command, thus avoiding resource waste.
[0159] In some embodiments of this application, after the measurement is completed, a stop positioning measurement request message sent by the LMF can also be received. That is, after the measurement is completed, the LMF can send a stop positioning measurement request message to the serving network device and neighboring serving network devices, so that the serving network device and neighboring serving network devices can stop positioning measurement, thus avoiding resource waste.
[0160] It should be noted that the actual execution order of steps S801, S802, S803, S804, and S805 does not necessarily have to follow the order described above. In other words, the steps described above, such as S801, S802, S803, S804, and S805, are for the convenience of those skilled in the art and for ease of description, and the actual execution order does not necessarily have to follow the order described above.
[0161] By implementing this embodiment, by configuring the SRS resource configuration for SRS-based positioning measurement of the terminal device in the inactive state, and sending the configured SRS resource configuration to the terminal device through the location management unit (LMF) in a transparent manner, the cellular network positioning technology can support the terminal device to perform uplink positioning measurement in the inactive state, thereby improving the efficiency and performance of cellular network positioning measurement and avoiding resource waste.
