The communication-sensing integration technology provides a new means for the mobile communication network to obtain data and information, which will bring new business opportunities to the 6G communication network.

[0098] The following combines the accompanying drawings and details the sensing method provided by the embodiments of the present application through some embodiments and their application scenarios.

[0099] Please refer to Figure 3 , Figure 3 which is a flowchart of a sensing method provided by the embodiments of the present application. This method can be executed by a sensing function network element. As Figure 3 shown, it includes the following steps:

[0100] Step 301, the sensing function network element receives a first sensing service request message from a first device, where the first sensing service request message is used to request the execution of a target sensing service.

[0101] In this embodiment, the above-mentioned first device may be a consumer of the target sensing service. For example, a UE, AF, LCS client, or network function (NF), etc. Alternatively, the above-mentioned first device may be a device between the sensing function network element and the consumer of the target sensing service, such as an AMF or GMLC, etc.

[0102] The above-mentioned first sensing service request message is used to request the sensing function network element to execute a target sensing service. Exemplarily, the above-mentioned target sensing service may include a positioning sensing service for a first terminal; or the above-mentioned target sensing service may include a sensing service that requires the location information of the first terminal for assistance. For example, the sensing result of the above-mentioned target sensing service needs to be calculated based on the location information of the first terminal for assistance.

[0103] Step 302, the sensing function network element performs a positioning sensing service for the first terminal according to the first sensing service request message to obtain the location information of the first terminal, where the first terminal is the sensing object of the target sensing service or the sensing device of the target sensing service or the auxiliary device of the target sensing service.

[0104] In this embodiment, when the first terminal is the perception object of the target perception service, the target perception service includes a positioning perception service for the first terminal; when the first terminal is the perception device of the target perception service, the target perception service may include at least one of a positioning perception service for the first terminal and a perception service that requires the location information of the first terminal for assistance; when the first terminal is the auxiliary device of the target perception service, the target perception service may be a perception service that requires the location information of the first terminal for assistance.

[0105] It should be noted that the first terminal may be any terminal. The perception device refers to a device that executes the target perception service and can be used for at least one of signal transmission perception, signal reception perception, signal measurement perception, and perception information acquisition.

[0106] Exemplarily, if the target perception service is a positioning perception service for the first terminal, the perception function network element may, upon receiving a first perception service request message, execute the positioning perception service for the first terminal to obtain the location information of the first terminal; if the target perception service is a first perception service that requires the location information of the first terminal for assistance, the perception function network element may, upon receiving a first perception service request message, execute the positioning perception service for the first terminal to obtain the location information of the first terminal, and execute the first perception service, and then may determine the perception result information of the first perception service based on the location information of the first terminal and the result information obtained by executing the first perception service.

[0107] It should also be noted that when the target perception service is a positioning perception service for the first terminal, after the perception function network element obtains the location information of the first terminal, it may feedback the location information of the first terminal to the first device, or the perception function network element may store the location information of the first terminal. For example, the perception function network element may execute a positioning perception service for the terminals around it and store the location information of the terminals around it to manage the location information of the terminals around the perception function network element; when the target perception service is a first perception service that requires the location information of the first terminal for assistance, after the perception function network element obtains the location information of the first terminal, it may calculate the perception result information of the first perception service based on the location information of the first terminal.

[0108] In an embodiment of the present application, a sensing function network element receives a first sensing service request message from a first device, where the first sensing service request message is used to request the execution of a target sensing service; the sensing function network element performs a positioning sensing service on a first terminal according to the first sensing service request message to obtain location information of the first terminal, where the first terminal is a sensing object of the target sensing service or a sensing device of the target sensing service or an auxiliary device of the target sensing service. That is, the embodiment of the present application provides a method for providing the location information of a terminal based on a sensing function network element, which can use a sensing function network element that supports multiple sensing service types to implement the positioning of a terminal, and then can omit function modules for providing terminal positioning services in related technologies, such as LMF. This is beneficial to simplifying network function modules. In addition, based on the location information of the first terminal, it is also possible to assist in obtaining the first sensing service or improving the accuracy of the first sensing service.

[0109] Optionally, the method further includes:

[0110] The sensing function network element sends the location information of the first terminal to the first device.

[0111] In this embodiment, after the sensing function network element obtains the location information of the first terminal, it can send the location information of the first terminal to the first device. It can be understood that if the first device is a consumer of the positioning service, such as a UE, AF, LCS client, or NF, etc., the first device can apply the location information of the first terminal or store the location information of the first terminal, etc. If the first device is a device between the sensing function network element and the consumer of the positioning service, such as an AMF or GMLC, etc., the first device can send the location information of the first terminal to the consumer of the positioning service, such as a UE, AF, LCS client, or NF, etc.

[0112] In some optional embodiments, when the above target sensing service is a positioning sensing service for the first terminal, the sensing function network element sends the location information of the first terminal to the first device.

[0113] Optionally, when the target sensing service includes a first sensing service for a first object, and the first terminal is a sensing device or an auxiliary device for executing the first sensing service, the method further includes:

[0114] The sensing function network element obtains sensing result information of the first sensing service based on the location information of the first terminal;

[0115] The sensing function network element sends the sensing result information of the first sensing service to the first device.

[0116] In this embodiment, the first object may be any object, for example, objects such as a terminal, a building, a vehicle, etc. In some alternative embodiments, the first object may be the first terminal.

[0117] The first perception service may be any perception service that requires the assistance of the location information of the first terminal. Exemplarily, the first perception service may be a positioning perception service for the first object, or may be a speed perception service for the first object, etc.

[0118] For example, in a scenario where a dual perception device (for example, the UE sends a perception signal and the RAN receives the perception signal) is used to perceive a target object, it is necessary to use the location information of the perception UE as a reference point to accurately calculate the location information of the target object. In this scenario, the perception functional network element needs to perform a positioning perception service for the UE to obtain the location information of the UE, and perform a positioning perception service for the target object to obtain the initial location information of the target object, and can determine the target location information of the target object based on the location information of the UE and the initial location information of the target object.

[0119] It can be understood that in the case where the target perception service includes the first perception service for the first object, the perception functional network element may also perform the first perception service for the first object to obtain the initial perception result information or the value of the perception measurement quantity of the first perception service, etc. Exemplarily, the perception functional network element may adjust the initial perception result information obtained by performing the first perception service based on the location information of the first terminal to obtain the perception result information of the first perception service; or, the perception functional network element may jointly calculate the perception result information of the first perception service based on the location information of the first terminal and the value of the perception measurement quantity obtained by performing the first perception service.

[0120] It should be noted that the perception result information of the first perception service may be the final result information of the first perception service or may be the intermediate result information of the first perception service. Among them, the intermediate result information of the first perception service can be understood as the intermediate information used to generate the final result information of the first perception service, and this intermediate information is fed back to the first device (such as a consumer) so that the first device can calculate the final service result based on this intermediate information and the internal service logic.

[0121] After obtaining the perception result information of the first perception service, the above-mentioned perception function network element may send the perception result information of the first perception service to the first device. It can be understood that if the first device is a consumer of the first perception service, for example, UE, AF, LCS client or NF, etc., the first device may apply the perception result information of the first perception service or store the perception result information of the first perception service, etc. If the first device is a device between the perception function network element and the consumer of the first perception service, for example, AMF or GMLC, etc., the first device may send the perception result information of the first perception service to the consumer of the first perception service, for example, UE, AF, LCS client or NF, etc.

[0122] This embodiment provides a method for assisting in the execution of other perception services (i.e., the first perception service) based on the location information of the first terminal, which is beneficial to obtaining the perception result of the first perception service or improving the accuracy of executing the first perception service.

Exemplarily, the above first sensing device may include at least one of a terminal, an access network device, etc. It can be understood that for different positioning sensing methods, the above first sensing device may be different. For example, for the positioning method of the access network device transmitting and receiving by itself or the access network device A transmitting and B receiving the sensing signal, the above first sensing device is the access network device; for the positioning method of the terminal transmitting and receiving by itself or the terminal A transmitting and B receiving the sensing signal, the above first sensing device is the terminal; for the positioning method where one of the access network device and the terminal transmits the sensing signal and the other receives the sensing signal, the above first sensing device may include the access network device and the terminal.

When the first sensing device receives the above-mentioned second sensing service request message, it can perform positioning sensing service for the first terminal. For example, for the positioning method of the access network device spontaneously transmitting and receiving sensing signals, the access network device can transmit and receive sensing signals, measure the received sensing signals, obtain the value of the first sensing measurement quantity, and then can feedback the value of the first sensing measurement quantity to the sensing function network element, or can calculate the location information of the first terminal based on the value of the first sensing measurement quantity and feedback the location information of the first terminal to the sensing function network element.

[0265] Optionally, when the target sensing service includes the first sensing service for the first object, the method further includes:

[0266] The first device receives the sensing result information of the first sensing service from the sensing function network element, where the sensing result information of the first sensing service is determined based on the location information of the first terminal.

[0267] It should be noted that the implementation method of this embodiment can refer to Figure 3 the relevant description of the embodiment shown, which will not be elaborated here.

[0268] Optionally, the first sensing service request message includes at least one of the following:

[0269] Information of the target object, where the target object is the sensing object of the target sensing service, and the target object includes at least one of the first terminal and the first object;

[0277] The first device receives a first request message from a second device, where the first request message is used to request the execution of a target sensing service, and the target sensing service includes at least one of a positioning sensing service for a first terminal and a first sensing service for a first object.

[0278] In this embodiment, the above-mentioned first device may be a device between a sensing functional network element and a consumer of the target sensing service. For example, it may be an AMF or a GMLC, etc. The above-mentioned second device may be a consumer of the target sensing service. For example, it may be a UE, an AF, an LCS client, or an NF, etc.

[0279] The above-mentioned first request message may be a sensing service request message, or it may be other types of request messages. For example, it may be a related technology or traditional positioning request message. Specifically, the first device receives the first request message from the second device and may send a first sensing service request message to the sensing functional network element according to the first request message.

[0283] Exemplarily, when the first device is an AMF, if the consumer is an untrusted AF or LCS client outside the network, the fifth sensing service request message can be sent to the AMF via the NEF. Among them, the NEF needs to authenticate the untrusted AF / LCS client and authorize whether it is allowed to obtain the fifth sensing service request message. If the consumer is a trusted AF or an NF within the network, the above-mentioned fifth sensing service request message can be directly sent to the AMF without passing through the NEF.

[0291] Sensing preset time for indicating the execution time of the target sensing service.

[0292] In some alternative embodiments, the first device receives a first positioning service request message from the second device. The first positioning service request message is used to request the execution of a positioning service. The first device may convert the positioning service requirement into a sensing service requirement and send a first sensing service request message to a sensing function network element. In this embodiment, the second device may still initiate the positioning service using related technologies or traditional positioning processes, that is, the second device sends the first positioning service request message to the first device, which helps to reduce the change of the signaling interaction on the second device side during the positioning process. Exemplarily, the first positioning service request message may include, but is not limited to, at least one of the following: information of the target UE, indication information of the service type being positioning, and LCS QoS requirement.

[0293] Optionally, the method further includes:

Wherein, when the target sensing service includes a positioning sensing service for the first terminal, the target sensing result information includes the location information of the first terminal; when the target sensing service includes a first sensing service for a first object, the target sensing result information includes the sensing result information of the first sensing service, or the target sensing result information includes the location information of the first terminal and the sensing result information of the first sensing service, and the sensing result information of the first sensing service is determined based on the location information of the first terminal.

[0295] In this embodiment, the above-mentioned first device may be a device between a sensing function network element and a consumer of the target sensing service. For example, it may be an AMF or a GMLC, etc. The above-mentioned second device may be a consumer of the target sensing service, such as a UE, an AF, an LCS client, or an NF, etc.

[0296] Optionally, the method further includes:

[0297] The first device selects a sensing function network element that supports the target sensing service.

[0298] In this embodiment, the above-mentioned first device may be a consumer of the target sensing service, such as a UE, an AF, an LCS client, or an NF, etc., or the above-mentioned first device may be a device between a sensing function network element and a consumer of the target sensing service, such as an AMF or a GMLC, etc.

[0299] Exemplarily, the first device may obtain the capability information of at least one sensing function network element, and may select a sensing function network element that supports the target sensing service based on the capability information of the at least one sensing function network element, and send a first sensing service request message to the selected sensing function network element.

[0301] The first device sends a network element discovery request message or a network element status request message to a Network Repository Function (NRF) network element;

[0302] The first device receives target network element information from the NRF network element;

[0303] The first device selects a sensing function network element that supports the target sensing service according to the target network element information.

[0304] Exemplarily, the first device may send a network element discovery request message or a network element status request message to the NRF network element. The NRF may determine a sensing function network element that supports the target sensing service based on the network element discovery request message or the network element status request message, and return the information of the sensing function network element that supports the target sensing service (i.e., the above-mentioned target network element information) to the first device. Furthermore, the first device may select a sensing function network element based on the information of the sensing function network element that supports the target sensing service, and send a first sensing service request message to the selected sensing function network element; or, the NRF may feedback the information of at least one sensing function network element (for example, the identifier of the sensing function network element, the capability information of the sensing function network element, etc.) to the first device based on the network element discovery request message or the network element status request message. Furthermore, the first device may select a sensing function network element that supports the above-mentioned target sensing service based on the information of the at least one sensing function network element (i.e., the above-mentioned target network element information), and send a first sensing service request message to the selected sensing function network element.

[0305] Optionally, the network element discovery request message or the network element status request message includes at least one of the following:

[0306] Network element type indication information, used to indicate that the target network element type is a sensing function network element;

[0307] Second indication information, used to indicate the sensing service that the target network element needs to support;

[0308] Area of Interest (AOI).

[0309] Exemplarily, for location-aware services, the specific form of the above network element type indication information may be: NF type = sensing function; the specific form of the above second indication information may be: Supported service name = sensing for location.

[0310] The above AOI may indicate the AOI of the services required by the target network element. Exemplarily, the above AOI may include a Tracking Area (TA) or a cell, etc. In some alternative embodiments, the first device (e.g., AMF) may set the AOI according to the network location where the sensing object of the target sensing service (e.g., the first terminal or the first object) is currently located. For example, the TA or cell where the sensing object of the target sensing service is currently located may be used as the AOI.

[0311] In this embodiment, the above network element discovery request message or network element status request message includes at least one of network element type indication information, second indication information, and AOI, which is conducive to the NRF more accurately feedbacking the target network element information.

[0312] In some alternative embodiments, the first device may verify at least one of the subscription information and user willingness information of the sensing object of the target sensing service (e.g., the first terminal or the first object). Among them, the above subscription information is used to verify whether the sensing object of the above target sensing service has subscribed to the target sensing service, and the above user willingness information is used to verify whether the sensing object of the above target sensing service allows the above target sensing service to be executed. For example, if the above target sensing service is a location-aware service for the first terminal, the above subscription information is used to verify whether the first terminal has subscribed to the location-aware service, and the above user willingness information is used to verify whether the sensing object of the above target sensing service allows the location-aware service to be executed. When the sensing object of the target sensing service has subscribed to the target sensing service and the sensing object of the above target sensing service allows the above target sensing service to be executed, the first device may send a first sensing service request message to the sensing function network element.

[0313] Optionally, the method further includes:

[0314] The first device sends the capability information of at least one sensing device to the sensing function network element;

[0315] Or,

[0316] The first device sends the information of at least one sensing device with positioning capabilities to the sensing function network element.

[0317] It should be noted that for the implementation method of this embodiment, reference can be made to Figure 3 the relevant description of the embodiments shown, which will not be elaborated here.

[0318] Please refer to Figure 5 , Figure 5 which is a flowchart of a perception method provided by an embodiment of this application. This method can be executed by a second device, such as Figure 5 shown, and includes the following steps:

[0319] Step 501, the second device sends a first request message to the first device, where the first request message is used to request to execute a target perception service, and the target perception service includes at least one of a positioning perception service for a first terminal and a first perception service for a first object.

[0320] In this embodiment, the above-mentioned first device can be a device between a perception function network element and a consumer of the target perception service. For example, it can be an AMF or a GMLC, etc. The above-mentioned second device can be a consumer of the target perception service. For example, it can be a UE, an AF, an LCS client or an NF, etc.

[0321] Optionally, when the target perception service includes a first perception service for a first object, the first terminal is a perception device for executing the target perception service or an auxiliary device for the target perception service.

[0322] Optionally, when the target perception service is a positioning perception service for a first terminal, the first request message includes a positioning service request message or a fifth perception service request message.

[0323] Optionally, the method further includes:

[0324] The second device receives target perception result information from the first device. Wherein, when the target perception service includes a positioning perception service for the first terminal, the target perception result information includes the location information of the first terminal; when the target perception service includes a first perception service for a first object, the target perception result information includes the perception result information of the first perception service, or the target perception result information includes the location information of the first terminal and the perception result information of the first perception service, and the perception result information of the first perception service is determined based on the location information of the first terminal.

[0325] Optionally, the first request message includes at least one of the following:

[0326] Information of a target object, where the target object is a perception object of the target perception service, and the target object includes at least one of the first terminal and the first object;

[0327] Type information of the target perception service, where the target perception service includes at least one of a first perception service and a positioning perception service;

[0328] First indication information, used to indicate a request to perform positioning perception on the first terminal;

[0329] Quality of Service (QoS) requirement information, used to represent the service quality requirements or levels that the target perception service needs to achieve;

[0330] Information of the perception device, used to represent the perception device that executes the target perception service;

[0331] Indication information of terminal non-sensing, used to indicate that the terminal or user does not sense the target perception service;

[0332] Perception preset time, used to represent the execution time of the target perception service.

[0333] It should be noted that the implementation method of this embodiment can refer to Figure 3 and Figure 4 the relevant descriptions of the embodiments shown, which will not be elaborated here.

[0334] The embodiments of the present application will be described below with examples:

[0335] Example 1: LCS client or AF, as a consumer of the sensing service, calls the sensing service provided by the SF network element. Specifically, the sensing type is set to UE location or UE position. The LCS client or NEF first finds the serving AMF of the target UE, and then uses the AMF to call the sensing service of the SF.

[0336] Exemplarily, as Figure 6a shown, the sensing method provided by the embodiments of the present application may include the following steps:

[0337] Step 1: A consumer (such as AF / LCS client / NF / UE, etc.) sends a fifth sensing service request message to the mobility management function (such as AMF), specifically indicating a request for the location information of the target UE (i.e., the first terminal), that is, a request to perform a positioning perception service for the target UE.

[0338] Among them, the above fifth sensing service request message carries at least one of the following:

[0339] Information of the target UE;

[0340] The type information of the positioning awareness service, i.e., Sensing type = UE location / positioning;

[0341] The first indication information is used to indicate a request for positioning awareness of the target UE.

[0342] The QoS requirement information is used to indicate the quality of service level information (such as positioning accuracy information) of the requested UE positioning.

[0343] The indication information of UE non-awareness is used to indicate that the terminal or user is not aware of the positioning awareness service.

[0344] The sensing preset time is used to represent the execution time of the positioning awareness service.

[0345] It should be noted that if the consumer is an untrusted AF or LCS client outside the network, the fifth sensing service request message is sent to the AMF via the NEF. Among them, the NEF needs to authenticate the untrusted AF / LCS client and authorize whether it is allowed to obtain the fifth sensing service request message. If the consumer is a trusted AF or an NF within the network, the above fifth sensing service request message can be directly sent to the AMF without passing through the NEF.

[0346] Exemplarily, in the case where the above consumer is an AF, as Figure 6a shown, step 1 above includes the following steps:

[0347] Step 1a, the AF sends a sensing service request message to the NEF;

[0348] Step 1b, the NEF authorizes the AF.

[0349] Step 1c, the NEF sends a sensing service request message to the AMF.

[0350] It should also be noted that if the consumer is an AF / LCS client / NF, the consumer can obtain the AMF serving the UE (i.e., the serving AMF) from the UDM / HSS, etc. in advance. If the consumer is a UE, the UE can send the fifth sensing service request message to the AMF based on the uplink NAS message.

[0351] Exemplarily, in the case where the above consumer is a UE, as Figure 6a shown, step 1 above may include:

[0352] Step 1d: The UE sends a sensing service request message to the AMF.

[0353] Step 2a: The AMF verifies at least one of the subscription information of the target UE and the user consent information. Among them, the above-mentioned subscription information of the target UE is used to determine whether the target UE has subscribed to the sensing service for positioning, and the above-mentioned user consent information is used to determine whether the target UE allows its location information to be sensed.

[0354] Exemplarily, the above-mentioned subscription information can be carried in a Subscription profile.

[0355] Step 2b: The AMF selects an SF that supports calculating the location information of the target UE, that is, the SF has positioning and sensing capabilities.

[0356] Optionally, the AMF can send a network element discovery request message or a network element status request message from the network storage function. The relevant content of the above-mentioned network element discovery request message or network element status request message can refer to the relevant descriptions in the foregoing embodiments and will not be elaborated here.

[0357] Step 3: The AMF sends a first sensing service request message to the SF to request the location information of the target UE, that is, to request to execute the positioning and sensing service for the target UE.

[0358] Among them, the relevant content of the above-mentioned first sensing service request message can refer to the relevant description of the first sensing service request message in the foregoing embodiments when the target sensing service is a positioning and sensing service and will not be elaborated here.

[0359] Step 4: The SF selects a sensing device (RAN / UE) with positioning and sensing capabilities.

[0360] Step 5: The SF determines the positioning and sensing method according to the first sensing service request message.

[0361] It should be noted that this example does not limit the execution order of the above steps 4 and 5.

[0362] Step 6: If the sensing device selected by the SF includes at least one RAN, the SF sends a second sensing service request message to the RAN to request the positioning-related information of the target UE, for example, positioning measurement information (that is, the value of the positioning measurement quantity) or positioning result (that is, the location information of the target UE). That is, the second sensing service request message is used to request to execute the positioning and sensing service for the target UE. Optionally, the above-mentioned at least one RAN may include Figure 6a the RAN shown in

[0363] Among them, the above second sensing service request message can be transmitted based on the peer sensing protocol between the SF and the RAN, such as the NRSPa protocol. The protocol layer message can be relayed by the AMF, but it may not be parsed by the AMF.

[0364] Step 7: If at least one UE is included in the sensing devices selected by the SF, the SF sends a second sensing service request message to the UE to request positioning-related information of the target UE.

[0365] Among them, the second sensing service request message can be transmitted based on the peer sensing protocol between the SF and the UE, such as the NRSP protocol. The protocol layer message is relayed by the AMF and the RAN, but it may not be parsed by the AMF and the RAN.

[0366] Optionally, before sending the second sensing service request message, the SF may also send a sixth sensing service request message to the target sensing device to obtain sensing assistance information. Among them, the above target sensing device may be the same as or different from the sensing device in step 6 or step 7 above.

[0367] Step 8: The SF determines the positioning result of the target UE, that is, the location information of the target UE, based on the positioning-related information reported by the sensing devices in at least one of step 6 and step 7, and feeds back the location information of the target UE to the AMF.

[0368] Exemplarily, the SF analyzes and calculates the positioning-related information reported by at least one sensing device through a preset algorithm to obtain the final positioning result of the target UE, that is, the location information of the target UE.

[0369] Step 9: The AMF feeds back the positioning result of the target UE to the corresponding consumer through the response message of the second sensing service request message, as shown in Figure 6a Steps 9a to 9c shown.

[0370] Example 2: Compared with the above Example 1, this Example 2 has the following differences:

[0371] For the MT LR scenario initiated by the LCS client / AF, one implementation is as follows: The LCS client / AF, as the consumer of the positioning service, calls the traditional positioning service provided by the GMLC, and the GMLC converts the positioning service requirement into a sensing service requirement and calls the sensing service provided by the AMF. Specifically, the GMLC sends a first sensing service request message to the AMF and sets the sensing type to UE location or UE position to inform the AMF that the requested sensing is the positioning information of the target UE. Another implementation is as follows: The consumer of the positioning service calls the traditional positioning service provided by the GMLC. The GMLC still calls the traditional positioning service provided by the AMF, and the AMF converts the positioning service requirement into a sensing service requirement and calls the sensing service provided by the SF.

[0372] For the MO LR scenario initiated by the target UE: The UE sends a traditional positioning service request message to the AMF, and the AMF converts the positioning service request message into a sensing service request message.

[0373] Exemplarily, as Figure 6b shown, the sensing method provided by the embodiments of the present application includes the following steps:

[0374] Step 1: A consumer (such as AF / LCS client / NF / UE, etc.) sends a positioning service request message to request a positioning service. For example, the above positioning service request message can be used to request a related technology or traditional positioning service.

[0375] Wherein, the above positioning service request message may include at least one of the following: information of the target UE, indication information with the service type being positioning, and LCS QoS requirement.

[0376] Exemplarily, when the above consumer is the AF, as Figure 6b shown, the above Step 1 includes the following steps:

[0377] Step 1a: The AF sends a positioning service request message to the GMLC;

[0378] Step 1b: The GMLC authorizes the AF.

[0379] Step 1c: The GMLC sends a sensing service request message to the AMF.

[0380] When the above consumer is the UE, as Figure 6b shown, the above Step 1 may include:

[0381] Step 1d: The UE sends a positioning service request message to the AMF.

[0382] Step 2a: The AMF verifies at least one of the subscription information and user consent information of the target UE. Among them, the above-mentioned subscription information of the target UE is used to determine whether the target UE has subscribed to the perception service for positioning, and the above-mentioned user consent information is used to determine whether the target UE allows its location information to be perceived.

[0383] Step 2b: The AMF selects an SF that supports calculating the location information of the target UE, that is, the SF has the positioning perception ability.

[0384] Step 3: The AMF sends a first perception service request message to the SF, which is used to request to obtain the location information of the target UE, that is, to request to execute the positioning perception service for the target UE.

[0385] Step 4: The SF selects a perception device (RAN / UE) with positioning perception ability.

[0386] Step 5: The SF determines the positioning perception method according to the first perception service request message.

[0387] It should be noted that this example does not limit the execution order of the above steps 4 and 5.

[0388] Step 6: If the perception device selected by the SF includes at least one RAN, the SF sends a second perception service request message to the RAN, which is used to request the positioning-related information of the target UE. For example, positioning measurement information (that is, the value of the positioning measurement quantity) or positioning result (that is, the location information of the target UE). That is, the second perception service request message is used to request to execute the positioning perception service for the target UE.

[0389] Step 7: If the perception device selected by the SF includes at least one UE, the SF sends a second perception service request message to the UE, which is used to request the positioning-related information of the target UE.

[0390] Step 8: The SF determines the positioning result of the target UE, that is, the location information of the target UE, according to the positioning-related information reported by the perception device in at least one of steps 6 and 7, and feeds back the location information of the target UE to the AMF.

[0391] Step 9: The AMF feeds back the positioning result of the target UE to the corresponding consumer through the response message of the second perception service request message. See, for example, Figure 6bSteps 9a to 9c shown in

[0392] Example 3: Assisting in the execution of other sensing services based on the location information of the UE.

[0393] For some sensing services (i.e., the above-mentioned first sensing service), it is necessary for the SF to execute the positioning sensing service for the target UE to assist in the execution. Among them, the above-mentioned positioning sensing service and the first sensing service can be executed synchronously or in a sequential order. Specifically, the SF uses the location information of the target UE as the input of the first sensing service to facilitate the calculation of the final result of the first sensing service or to improve the accuracy of the first sensing service based on the location information of the target UE.

[0394] For example, in the scenario of using dual sensing devices (e.g., the UE sends sensing signals and the RAN receives sensing signals) to sense the target object, it is necessary to use the location information of the sensing UE as a reference point to accurately calculate the location information of the target object. In this scenario, the sensing functional entity needs to execute the positioning sensing service for the UE to obtain the location information of the UE, and execute the positioning sensing service for the above-mentioned target object to obtain the initial location information of the above-mentioned target object, and can determine the target location information of the above-mentioned target object based on the location information of the UE and the initial location information of the above-mentioned target object. In this scenario, the SF triggers two sensing services. One sensing type is the location / positioning of the target UE; the other sensing type is the other sensing service of the target object. Among them, the target UE will serve as one of the sensing devices for the other sensing service of the target object, and the location information of the target UE will be used as an input for the other sensing service of the target object.

[0395] The process of this Example 3 is basically similar to that of the above Example 1. Refer to Figure 6c , the difference is that:

[0396] In steps 1-3, the consumer and the AMF can indicate in the process that the sensing type includes location and other. This other can represent any sensing type different from location, and can be specifically determined according to the type of the first sensing service. Hereinafter, an example will be given with other representing the sensing service type 1. However, the consumer and the AMF can also only indicate the required sensing service type 1, and then it is decided by the SF that the positioning sensing service also needs to be executed.

[0397] Optionally, in step 2b, if the AMF determines that the sensing service type 1 requires assistance for the positioning sensing service, the AMF may choose to support the SF for two sensing services.

[0398] Optionally, in step 3, the AMF may select the sensing device RAN / UE and send the sensing device information to the SF. The sensing device includes at least one of the following: the sensing device RAN2 that executes the sensing service type 1 and the target UE, the sensing device RAN1 and the target UE that execute the positioning sensing service of the target UE. The above RAN1 and RAN2 may be the same or different.

[0399] Optionally, in step 4, the SF selects the sensing device RAN / UE. The sensing device may include at least one of the following: the sensing device RAN2 that executes the sensing service type 1 and the target UE, the sensing device RAN1 and the target UE that execute the positioning sensing service of the target UE. The above RAN1 and RAN2 may be the same or different.

[0400] In step 5, the SF determines the sensing method corresponding to the sensing service type 1. Here, the sensing method includes but is not limited to: performing the sensing service type 1 based on the location service assistance of the sensing device target UE.

[0401] It should be noted that the above step 4 may be executed after step 5.

[0402] Step 6, if the sensing device selected by the SF includes at least one RAN, the SF sends a fourth sensing service request message to the RAN. In this case, RAN1 and RAN2 may be the same. Correspondingly, the SF will obtain the feedback information of the RAN, that is, the above third feedback information and fourth feedback information.

[0403] Step 7, if the sensing device selected by the SF includes at least one UE, the SF sends a fourth sensing service request message to the UE. In this case, the above UE may be the target UE.

[0404] Correspondingly, the SF will obtain the feedback information of the UE, that is, the above third feedback information and fourth feedback information.

[0405] The other steps of Example 3 are similar to those of Example 1 and will not be elaborated here.

[0406] It should be noted that in this example, the sensing devices for the positioning and sensing service are RAN1 and target UE (where the sensing object is the target UE at this time), and the sensing devices for sensing service type 1 are RAN2 and target UE (where the sensing object is the target object at this time). RAN1 and RAN2 can be the same or different. In addition, in Figure 6c In steps 6 and 7 shown, taking the SF synchronization (in the same message) to require the RAN / UE to execute location and sensing service type 1 as an example. In some alternative implementation manners, SF can also trigger the two sensing services separately (requesting in two messages), that is, first require the RAN / UE to execute the positioning and sensing service, and then request the RAN / UE to execute sensing service type 1, or first require the RAN / UE to execute sensing service type 1, and then request the RAN / UE to execute the positioning and sensing service.

[0407] In summary, the embodiment of the present application uses a unified sensing functional network element to provide traditional UE positioning services, which is beneficial to simplifying network functional modules and avoiding problems such as excessive functional modules, complex interactions, and duplicate functions.
