[0024] The following describes in detail, with reference to the drawings, the method and device for realizing the sensing service provided by the embodiments of this application, based on several embodiments and their application scenarios.

[0025] As shown in Figure 2, an embodiment of the present application provides a method 200 for implementing a sensing service, the method being executable by a first access network device, or in other words, the method being executable by software or hardware installed on the first access network device, the method comprising the following steps.

[0026] In S202, the first access network device acquires sensing instruction information regarding the terminal, and the first access network device is the access network device for the terminal's service.

[0027] In this embodiment, the first access network device may be a base station, for example, a gNB.

[0028] In this embodiment, the first access network device can acquire sensing instruction information related to terminals of the first access network device service. Depending on the terminal, the associated sensing instruction information may differ. For example, sensing instruction information related to terminal 1 is sensing instruction information 1, and sensing instruction information related to terminal 2 is sensing instruction information 2.

[0029] Selectively, the sensing instruction information relating to the terminal is for indicating at least one of the following: 1) whether the terminal permits the execution of a sensing task; 2) the sensing capabilities of the terminal, such as supported sensing methods, supported sensing signals (transmission or measurement), sensing frequency bands that support transmission or measurement, sensing measurement capabilities, etc.; 3) whether the terminal's position is constant; and 4) whether the terminal is a sensing measurement unit.

[0030] In S204, the first access network device receives a sensing measurement request message, which is a message not associated with a terminal.

[0031] The measurement request message may be sent from the sensing server to the first access network device. In this embodiment, for example, if the sensing server receives a sensing request message from a third party or the core network that is not associated with any terminal, it means that the core network or the third party has not selected a specific terminal to perform the sensing task. The sensing request message may be for the purpose of, for example, sensing weather conditions in a certain area, monitoring air pollution, pedestrian traffic, traffic congestion, etc. Thus, the sensing server may determine one or more first access network devices in the coverage area that overlap with the sensing area based on the received sensing request message, for example, sensing area information, and send a sensing measurement request message to the first access network device to request that the first access network device perform sensing measurements.

[0032] The sensing and measurement request message may optionally include the type of sensing request (e.g., weather sensing, air sensing, etc.), area information sensing, sensing quality of service (QoS), etc.

[0033] In S206, the first access network device determines a terminal to perform the sensing task based on the sensing instruction information.

[0034] The first access network device stores context information, including sensing instruction information, for terminals that are connected to Radio Resource Control (RRC) and those that are RRC disabled. Based on the sensing instruction information for each terminal stored (at least partially), the first access network device determines (also called selecting) which terminal to perform the sensing task on.

[0035] A terminal for performing a sensing task, as determined by the first access network device, is selectable to satisfy at least one of the following: 1) permitting the performance of the sensing task; 2) having sensing capabilities to support the sensing task; 3) being in an RRC connected state; 4) being in an RRC deactivated state; 5) being in a constant location; 6) being a sensing measurement unit; and 7) fitting into a sensing area corresponding to the sensing task. However, 3) and 4) are not usually satisfied simultaneously.

[0036] If, optionally, a terminal for performing the sensing task is in an RRC-deactivated state, the method further includes the step of the first access network device sending a paging message to page the terminal in the RRC-deactivated state in all or some of the cells of the first access network device. In this embodiment, no paging message is issued within the range of the Radio Access Network (RAN) Notification Area (RNA), i.e., no RAN paging message is sent to other access network devices within the RNA, thus contributing to the saving of network resources.

[0037] According to the method for realizing a sensing service provided by the embodiment of this application, the first access network device acquires sensing instruction information regarding a terminal. When the first access network device receives a sensing measurement request message that is not associated with a terminal, it can determine which terminal to execute the sensing task based on the sensing instruction information. Depending on the sensing scene, the first access network device may have a clearer understanding of terminal-related information, such as the approximate location of the terminal and the RRC status of the terminal, than the core network device can. Therefore, the first access network device can select a more appropriate terminal to execute the sensing task, thereby better satisfying the requirements of the sensing service.

[0038] Optionally, in S202, the step of the first access network device acquiring sensing instruction information about a terminal may include at least one of the following 1) to 3).

[0039] 1) The first access network device receives the sensing instruction information from the core network device. In this embodiment, the core network device may transmit sensing instruction information relating to a terminal to the first access network device. This sensing instruction information may be determined by the user at the time of contract and stored in the user database. When registering a terminal, the core network device obtains the sensing instruction information for the terminal from the user database.

[0040] 2) The first access network device receives the sensing instruction information from the terminal. In this embodiment, the terminal may transmit the sensing instruction information to the first access network device that provides the service.

[0041] 3) The first access network device receives the sensing instruction information from the second access network device. The first access network device is the access network device for the terminal's service after switching, after RRC reconstruction, or after RRC recovery, and the second access network device is the access network device for the terminal's service before switching, before RRC reconstruction, or before RRC recovery. That is, the first access network device is the access network device for the terminal's service after switching, and the second access network device is the access network device for the terminal's service before switching, or the first access network device is the access network device for the terminal's service after RRC reconstruction, and the second access network device is the access network device for the terminal's service before RRC reconstruction, or the first access network device is the access network device for the terminal's service after RRC recovery, and the second access network device is the access network device for the terminal's service before RRC recovery.

[0042] Optionally, after the step in which a first access network device acquires sensing instruction information relating to a terminal, the method further includes the step in which the first access network device transmits the sensing instruction information to a third access network device. The first access network device is an access network device for the terminal's service before switching, before RRC reconstruction, or before RRC recovery, and the third access network device is an access network device for the terminal's service after switching, after RRC reconstruction, or after RRC recovery. That is, the first access network device is an access network device for the terminal's service before switching, and the third access network device is an access network device for the terminal's service after switching, or the first access network device is an access network device for the terminal's service before RRC reconstruction, and the third access network device is an access network device for the terminal's service after RRC reconstruction, or the first access network device is an access network device for the terminal's service before RRC recovery, and the third access network device is an access network device for the terminal's service after RRC recovery.

[0043] Selectively, based on each of the above embodiments, after the step in which the first access network device determines a terminal for performing a sensing task based on the sensing instruction information, the method further includes at least one of the following 1) and 2):

[0044] 1) The method further includes the step of the first access network device transmitting a sensing signal, wherein the terminal for performing the sensing task is for generating a measurement result based on the sensing signal; and the first access network device receiving the measurement result.

[0045] If the first access network device optionally transmits a sensing signal, the method further includes the step of the first access network device transmitting measurement configuration information, which includes at least one of the following: resource configuration for the sensing signal, trigger conditions for receiving the sensing signal, and means for reporting the measurement results.

[0046] 2) The method further includes the steps of: the first access network device receiving a sensing signal transmitted from a terminal for performing the sensing task; and the first access network device generating a measurement result based on the sensing signal.

[0047] If the first access network device optionally receives a sensing signal, the method further includes the step of the first access network device transmitting sensing signal configuration information, including resource settings for the sensing signal.

[0048] To explain in detail how the sensing service provided by the embodiments of this application is implemented, the following description will be given with reference to specific embodiments.

[0049] Example 1 In this embodiment, the base station (corresponding to the first access network device in the above embodiment) acquires sensing instruction information from the core network. The flowchart of this embodiment includes the following steps, as shown in Figure 3.

[0050] In Step 1, the terminal and the base station establish an RRC connection.

[0051] In step 2, the base station sends an Initial UE Message to the core network.

[0052] In step 3, the core network sends an Initial Context Setup Request message to the base station. This message contains sensing instruction information, which includes one or any combination of the following (1) to (3):

[0053] (1) This is instruction information indicating whether the terminal is permitted to detect. This instruction information may be, for example, 1 bit. If its value is 1, it indicates that detection by the terminal is permitted.

[0054] (2) The sensing capability of the terminal. The sensing capability of the terminal includes, for example, the sensing methods it supports, the sensing signals it supports (transmit or measure), the sensing frequency band it supports for transmission or measurement, and its sensing and measuring capabilities.

[0055] Optionally, the sensing capability of the terminal may be part of the terminal's wireless access capability. In other words, sensing capability information is embedded in the terminal's wireless access capability. The core network can acquire the terminal's wireless access capability.

[0056] (3) Other characteristics of the terminal, such as whether the terminal is a stationary (non-moving) terminal or whether the terminal is a sensing and measuring unit.

[0057] In step 4, the base station stores the corresponding sensing instruction information for the terminal obtained from the core network.

[0058] In step 5, the base station sends an Initial Context Setup Response message to the core network and transitions to a connected state.

[0059] In step 6, the sensing server receives a sensing request from, for example, a third party or the core network, which is not associated with any UE. In other words, the core network or the third party has not selected a specific UE to perform the sensing measurement. The sensing request may be for, for example, to sense the weather conditions in a certain area, monitor air pollution, pedestrian traffic, traffic congestion, etc. The sensing request may include the type of sensing request (e.g., sensing weather, sensing air, etc.), sensing area information, sensing QoS, etc.

[0060] In step 7, the sensing server determines (one or more) target base stations based on the sensing request, for example, sensing area information, and requests the target base stations to perform sensing measurements by sending a first message (for example, a sensing measurement request message) to the target base stations.

[0061] The first message may contain one or any combination of the following information: the sensing method, the amount to be sensed, the sensing area (the area where the target sensing area or sensing measurement terminal is located), the number of UEs to be sensed and measured, the number of measurements reported by each UE, and the type of report (whether to report the measurement amount or the sensing result).

[0062] It should be explained that the first message is a non-UE associated message, or also called a global message. The first message may be a protocol stack message (e.g., SP2) between the base station and the sensing server. The first message may be transmitted to the target base station via the core network, but the next-generation application protocol (NGAP) message (i.e., the protocol stack message between the core network and the base station) carrying the message is a non-UE associated message, that is, it does not carry the UE NGAP ID assigned to the base station (i.e., the RAN UE NGAP ID).

[0063] In step 8, the base station stores context information for terminals in the RRC connection state and the deactivated state, which includes sensing instruction information. Based on the sensing instruction information for each stored terminal (at least partially), the base station determines (selects) which terminal to perform sensing. For example, it may select from terminals that satisfy any one or more combinations of the following conditions:

[0064] 1) By selecting the devices that are permitted to be detected, privacy protection requirements are met and user privacy is protected.

[0065] 2) Select a sensing-capable terminal to support the sensing task. For example, the base station will exclude terminals that are inactive and select terminals that are in an RRC connection state, thereby avoiding the process of terminals transitioning to an RRC connection state and reducing sensing delay.

[0066] 3) Select the terminal that is in RRC connection status.

[0067] 4) Select a terminal or sensing / measuring unit with a fixed position.

[0068] Of course, when selecting a terminal, the base station may take into account other factors in addition to the sensing instruction information. For example, the base station may evaluate the direction of each terminal based on the received beam of each corresponding terminal and evaluate the (approximate) distance from the terminal to the base station based on the measurement results reported by the terminal. Thus, the base station can select a terminal that fits the sensing area in the first message. Fit, here, may mean that, as a result of the evaluation, the terminal is located in the sensing area. Because the base station has this additional information, it can select a more appropriate (i.e., better-fitting to the sensing area) terminal by performing sensing measurements than by terminal selection by the core network, thereby better satisfying the sensing requirements.

[0069] The base station may make a multi-stage selection as an option. For example, it may first select some terminals (e.g., terminals that have allowed sensing and are connected) and instruct them to take measurements, and then further select more appropriate terminals based on the measurement results.

[0070] Selectively, a base station may select a terminal that is in an RRC-deactivated state based on the context of the terminal. For example, if there is no suitable terminal in an RRC-connected state, or if a terminal in an RRC-deactivated state is a suitable sensing measurement unit for performing sensing, the base station may select a terminal in an RRC-deactivated state. If a terminal in an RRC-deactivated state is selected as a terminal for sensing, the base station issues a paging message to page the terminal in all or only some of the cells at the base station (unlike the usual case where a paging message is issued within the RNA range, i.e., by not sending a RAN paging message to other base stations within the RNA, thereby saving network resources). If the terminal is located in a cell at the base station, it transitions to an RRC-connected state upon receiving the paging message. Other operations are the same as for a terminal in an RRC-connected state.

[0071] In step 9, the sensing measurement may be a sensing measurement by the terminal against a sensing signal transmitted from the base station, or a sensing measurement by the base station against a sensing signal transmitted from the terminal. If the sensing signal is transmitted from the base station, steps 9a to 12a are performed, and if the sensing signal is transmitted from the terminal, steps 9b to 11b are performed.

[0072] In step 9a, the base station transmits measurement settings for the sensing signal to the terminal, including parameter settings for the time domain and frequency domain of the sensing signal, trigger conditions, reporting means (e.g., whether it is periodic or not).

[0073] In step 10a, the base station transmits a sensing signal. Steps 9a and 10a can be performed in any order.

[0074] In step 11a, the terminal performs a sensing measurement.

[0075] In step 12a, when the trigger condition is met, the terminal transmits the sensing measurement result to the base station. The measurement result may be transmitted as a single result or as multiple results, for example, periodically.

[0076] In step 9b, the base station transmits the sensing signal transmission settings to the terminal, including the time domain and frequency domain parameter settings for the sensing signal.

[0077] In step 10b, the terminal transmits a sensing signal based on the sensing signal transmission settings.

[0078] In step 11b, the base station performs a sensing measurement and obtains the sensing measurement results. Optionally, it generates sensing results based on the sensing measurement results.

[0079] In step 13, the base station transmits the sensing measurement result or the sensing measurement response or sensing measurement report containing the sensing result to the sensing server.

[0080] In step 14, upon receiving a sensing measurement result, the sensing server may obtain a sensing result by performing calculations based on the sensing measurement result, or it may receive the sensing result from the terminal. The sensing server may decide whether or not to trigger the transmission of a sensing response to a third party or the core network. For example, if the sensing result is undesirable, the server may receive more sensing measurement results and receive a sensing result that satisfies the requirements, thereby triggering the transmission of a sensing response containing the sensing result to a third party or the core network.

[0081] In Example 1, if a switch occurs in a terminal, the original base station may optionally transmit the detection instruction information to the target base station, for example, by including it in a switch request message. The target base station stores the detection instruction information for the terminal. The specific procedure is shown in Figure 4.

[0082] In Example 1, if a terminal optionally undergoes RRC reconstruction or transitions from an inactive state to a connected state (RRC recovery), the old base station may transmit sensing instruction information to the new base station (i.e., the base station targeted for reconstruction or recovery), for example, in a Retrieve UE Context Response message. The new base station stores the sensing instruction information for the terminal. The specific procedure is shown in Figure 5.

[0083] Therefore, for a terminal in an RRC connection state, even if a switchover occurs, the terminal's current service base station will always store the terminal's sensing instruction information.

[0084] Example 2 In this embodiment, the base station acquires sensing instruction information from the terminal.

[0085] In Example 1, the base station obtains sensing instruction information from the core network. However, in this embodiment, the base station obtains sensing instruction information from the terminal, which is the only difference. The other aspects are almost the same as in Example 1, so they will not be repeated here.

[0086] As shown in Figure 6, the embodiment includes the following steps.

[0087] In step 1, the terminal enters an RRC connection state and sends an RRC message containing sensing instruction information to the base station.

[0088] The RRC message may be an RRC construction completion message or a UE Assistance Information message, or it may be a message sent at the request of the base station. For example, the base station requests the terminal to send sensing instruction information by sending a UE Information Request message to the terminal, and the terminal sends a UE Information Response message containing the sensing instruction information to the base station.

[0089] In step 2, the base station stores the sensing instruction information.

[0090] The method for realizing the sensing service according to the embodiment of this application has been described in detail above with reference to Figures 2 to 6. The method for realizing the sensing service according to the embodiment of this application will now be described in detail with reference to Figures 7 and 8. The explanations from the core network device and terminal side are the same as or correspond to the explanation from the first access network device side in the method shown in Figure 2, and relevant explanations will be omitted as appropriate to avoid duplication.
