[0110] In an embodiment of the present application, a perception function network element receives a first perception service request message from a first device, wherein the first perception service request message is used to request execution of a target perception service; the perception function network element executes a positioning perception service for the first terminal according to the first perception service request message to obtain the location information of the first terminal, wherein the first terminal is the perception object of the target perception service or the perception device of the target perception service or an auxiliary device of the target perception service, that is, an embodiment of the present application provides a method for providing the location information of the terminal based on the perception function network element, which can realize the positioning of the terminal by using the perception function network element that supports multiple types of perception services, and thus the functional module for providing terminal positioning services in the related technology, such as LMF, can be omitted, which is conducive to simplifying the network functional module; in addition, it can also be based on the location information of the first terminal to assist in the acquisition of the first perception service or improve the accuracy of the first perception service.

[0111] Optionally, the method further includes:

[0112] The perception function network element sends the location information of the first terminal to the first device.

[0113] In this embodiment, after acquiring the location information of the first terminal, the perception function network element may send the location information of the first terminal to the first device. It is understandable that if the first device is a consumer of positioning services, such as a UE, AF, LCS client, or NF, the first device may apply the location information of the first terminal or store the location information of the first terminal. If the first device is a device between the perception function network element and the consumer of positioning services, such as an AMF or GMLC, the first device may send the location information of the first terminal to the consumer of positioning services, such as a UE, AF, LCS client, or NF.

[0114] In some optional embodiments, when the target perception service is a positioning perception service for the first terminal, the perception function network element sends the location information of the first terminal to the first device.

[0115] Optionally, when the target perception service includes a first perception service for a first object, and the first terminal is a perception device or an auxiliary device that performs the first perception service, the method further includes:

[0116] The perception function network element obtains perception result information of the first perception service based on the location information of the first terminal;

For example, the first perception service can be a positioning perception service for the first object, or can be a speed perception service for the first object, etc.

[0120] For example, in a scenario where a dual sensing device (for example, UE sends a sensing signal and RAN receives a sensing signal) is used to sense a target object, the location information of the sensing UE needs to be used as a reference point to accurately calculate the location information of the target object. In this scenario, the sensing function network element needs to perform positioning sensing services on the UE to obtain the UE's location information, and perform positioning sensing services on 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 UE's location information and the initial location information of the above-mentioned target object.

[0121] It is understandable that, when the target perception service includes a first perception service for a first object, the perception function network element may further execute the first perception service for the first object to obtain initial perception result information or a perception measurement value of the first perception service. Exemplarily, the perception function network element may adjust the initial perception result information obtained by executing the first perception service based on the location information of the first terminal to obtain perception result information of the first perception service; or, the perception function 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 perception measurement value obtained by executing the first perception service.

[0122] 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 the intermediate result information of the first perception service. The intermediate result information of the first perception service may be understood as intermediate information used to generate the final result information of the first perception service, which is fed back to the first device (e.g., the consumer) so that the first device can calculate the final service result based on the intermediate information and internal service logic.

[0123] After acquiring the perception result information of the first perception service, the above-mentioned perception function network element can 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, such as UE, AF, LCS client or NF, the first device can 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, such as AMF or GMLC, the first device can send the perception result information of the first perception service to the consumer of the first perception service, such as UE, AF, LCS client or NF, etc.

[0124] This embodiment provides a method for assisting in executing other perception services (ie, the first perception service) based on the location information of the first terminal, which is conducive to obtaining the perception result of the first perception service or improving the accuracy of executing the first perception service.

[0165] In this embodiment, the first sensing device is used to perform a positioning sensing service for the first terminal. Exemplarily, the first sensing device may include at least one of a terminal, an access network device, etc. It is understandable that the first sensing device may be different for different positioning sensing modes. For example, for a positioning mode in which the access network device transmits and receives sensing signals on its own or in which access network device A transmits and B receives sensing signals, the first sensing device is the access network device; for a positioning mode in which the terminal transmits and receives sensing signals on its own or in which terminal A transmits and B receives sensing signals, the first sensing device is the terminal; for a positioning mode in which one of the access network device and the terminal transmits sensing signals and the other receives sensing signals, the first sensing device may include both the access network device and the terminal.

[0166] The above-mentioned second sensing service request message is used to request the first sensing device to perform a positioning sensing service for the first terminal. Upon receiving the above-mentioned second sensing service request message, the first sensing device can perform a positioning sensing service for the first terminal. For example, for a positioning method in which an access network device sends and receives sensing signals by itself, the access network device can send and receive sensing signals, and can measure the received sensing signals to obtain a value of a first sensing measurement quantity, and then can feed back 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 feed back the location information of the first terminal to the sensing function network element.

[0320] Please refer to FIG5 , which is a flowchart of a sensing method provided in an embodiment of the present application. The method can be performed by the second device, as shown in FIG5 , including the following steps:

[0321] Step 501: The second device sends a first request message to the first device, wherein the first request message is used to request execution of 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.

[0322] In this embodiment, the first device may be a device between the perception function network element and the target perception service consumer, such as AMF or GMLC, etc. The second device may be a target perception service consumer, such as UE, AF, LCS client or NF, etc.

[0323] Optionally, in a case where the target perception service includes a first perception service for a first object, the first terminal is a perception device that executes the target perception service or an auxiliary device of the target perception service.

[0324] Optionally, when the target perception service is a positioning perception service for the first terminal, the first request message includes a positioning service request message or a fifth perception service request message.

[0325] Optionally, the method further includes:

[0326] 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.

[0327] Optionally, the first request message includes at least one of the following:

[0328] Information of a target object, where the target object is a sensing object of the target sensing service, and the target object includes at least one of the first terminal and the first object;

[0329] Type information of a target perception service, where the target perception service includes at least one of a first perception service and a positioning perception service;

[0330] First indication information, used to indicate a request for positioning awareness of the first terminal;

[0331] Quality of service (QoS) requirement information, used to indicate the quality of service requirement or level that the target perception service needs to achieve;

[0332] Information of a sensing device, used to indicate the sensing device that performs the target sensing service;

[0333] The terminal is not aware of the indication information, which is used to indicate that the terminal or user is not aware of the target perception service;

[0334] The perception preset time is used to indicate the execution time of the target perception service.

[0335] It should be noted that the implementation of this embodiment can refer to the relevant descriptions of the embodiments shown in Figures 3 and 4, and will not be described in detail here.

[0336] The following examples illustrate the embodiments of the present application:

[0337] Example 1: As a consumer of a sensing service, the LCS client or AF invokes 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 locates the serving AMF for the target UE and then uses the AMF to invoke the sensing service provided by the SF.

[0338] For example, as shown in FIG6a , the sensing method provided in the embodiment of the present application may include the following steps:

[0339] Step 1. The consumer (such as AF / LCS client / NF / UE, etc.) initiates a fifth perception service request message to the mobility management function (such as AMF), specifically indicating the location information of the target UE (ie, the first terminal), that is, requesting the execution of the positioning perception service for the target UE.

[0340] The fifth perception service request message carries at least one of the following:

[0341] target UE information;

[0342] Positioning sensing service type information, i.e., Sensing type = UE location / positioning;

[0343] The first indication information is used to indicate a request for positioning awareness of the target UE;

[0344] QoS requirement information, used to indicate the service quality level information (such as positioning accuracy information) of the requested UE positioning;

[0345] UE-unaware indication information is used to indicate that the terminal or user is not aware of the positioning awareness service;

[0346] The perception preset time is used to indicate the execution time of the positioning perception service.

[0347] It should be noted that if the consumer is an untrusted AF or LCS client outside the network, the fifth perception service request message is sent to the AMF through the NEF. Among them, the NEF needs to authenticate the untrusted AF / LCS client and authorize whether it can obtain the fifth perception service request message. If the consumer is a trusted AF or NF within the network, the above-mentioned fifth perception service request message can be sent directly to the AMF without passing through the NEF.

[0348] For example, when the consumer is AF, as shown in FIG6a , step 1 includes the following steps:

[0349] Step 1a: AF sends a service awareness request message to NEF;

[0350] Step 1b: NEF authorizes AF.

[0351] Step 1c: NEF sends a service awareness request message to AMF.

[0352] 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., serving AMF) from the UDM / HSS in advance. If the consumer is a UE, the UE can send the fifth perception service request message to the AMF based on the uplink NAS message.

[0353] Exemplarily, in the case where the consumer is a UE, as shown in FIG6a , step 1 may include:

[0354] Step 1d: The UE sends a service awareness request message to the AMF.

[0355] Step 2a, AMF verifies at least one of the target UE's subscription information and user consent information, wherein the above-mentioned target UE's subscription information 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 the perception of location information.

[0356] Exemplarily, the above-mentioned contract information may be carried in a contract file (Subscription profile).

[0357] Step 2b: AMF selects an SF that supports calculating the location information of the target UE, that is, the SF has positioning awareness capability.

[0358] Optionally, AMF can send a network element discovery request message or a network element status request message from the network storage function, wherein the relevant content of the above-mentioned network element discovery request message or network element status request message can be found in the relevant description of the aforementioned embodiment and will not be repeated here.

[0359] Step 3: AMF sends a first perception service request message to SF, requesting to obtain the location information of the target UE, that is, requesting to execute the positioning perception service for the target UE.

[0360] Among them, the relevant content of the above-mentioned first perception service request message can refer to the relevant description of the first perception service request message in the aforementioned embodiment when the target perception service is a positioning perception service, and will not be repeated here.

[0361] Step 4: SF selects a sensing device (RAN / UE) with positioning sensing capabilities.

[0362] Step 5: SF determines the positioning perception mode according to the first perception service request message.

[0363] It should be noted that this example does not limit the order in which steps 4 and 5 are executed.

[0364] 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, requesting positioning-related information of the target UE, such as positioning measurement information (i.e., the value of the positioning measurement quantity) or positioning result (i.e., the location information of the target UE). In other words, the second sensing service request message is used to request execution of a positioning sensing service for the target UE. Optionally, the at least one RAN may include the RAN shown in Figure 6a.

[0365] Among them, the above-mentioned second perception service request message can be transmitted based on the peer perception protocol between SF and RAN, such as the NRSPa protocol. The protocol layer message can be transferred through AMF, but may not be parsed by AMF.

[0366] Step 7: If the sensing devices selected by the SF include at least one UE, the SF sends a second sensing service request message to the UE to request positioning-related information of the target UE.

[0367] Among them, the second perception service request message can be transmitted based on the peer perception protocol between SF and UE, such as the NRSP protocol. The protocol layer message is transferred through AMF and RAN, but may not be parsed by AMF and RAN.

[0368] Optionally, before sending the second perception service request message, the SF may also send a sixth perception service request message to the target perception device to obtain perception auxiliary information. The target perception device may be the same as or different from the perception device in step 6 or step 7 above.

[0369] 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 perception device in at least one of steps 6 and 7, and feeds back the location information of the target UE to the AMF.

[0370] Exemplarily, the SF analyzes and calculates the positioning-related information reported by at least one sensing device through a preset algorithm to obtain a final positioning result of the target UE, that is, the location information of the target UE.

[0371] Step 9: 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, as shown in steps 9a to 9c in Figure 6a.

[0372] Example 2: Compared with Example 1 above, Example 2 has the following differences:

[0373] For the MT LR scenario initiated by the LCS client / AF, one implementation method is: the LCS client / AF acts as a consumer of positioning services, and calls the traditional positioning services provided by the GMLC, while the GMLC converts the positioning service requirements into perception service requirements, and calls the perception services provided by the AMF. Specifically, the GMLC sends a first perception service request message to the AMF, and sets the sensing type to UE location or UE position, to inform the AMF that the requested perception is of the positioning information of the target UE. Another implementation method is: the consumer of positioning services, which calls the traditional positioning services provided by the GMLC. The GMLC still calls the traditional positioning services provided by the AMF, while the AMF converts the positioning service requirements into perception service requirements, and calls the perception services provided by the SF.

[0374] 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 an awareness service request message.

[0375] For example, as shown in FIG6b , the sensing method provided in the embodiment of the present application includes the following steps:

[0376] 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 positioning service request message may be used to request related technologies or traditional positioning services.

[0377] The positioning service request message may include at least one of the following: information of the target UE, indication information that the service type is positioning (location), and LCS QoS requirement (requirement).

[0378] For example, when the consumer is AF, as shown in FIG6b , step 1 includes the following steps:

[0379] Step 1a: AF sends a positioning service request message to GMLC;

[0380] Step 1b: GMLC authorizes AF.

[0381] Step 1c: GMLC sends a perception service request message to AMF.

[0382] In the case where the consumer is a UE, as shown in FIG6b , step 1 may include:

[0383] Step 1d: The UE sends a location service request message to the AMF.

[0384] Step 2a, AMF verifies at least one of the target UE's subscription information and user consent information, wherein the above-mentioned target UE's subscription information 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 the perception of location information.

[0385] Step 2b: AMF selects an SF that supports calculating the location information of the target UE, that is, the SF has positioning awareness capability.

[0386] Step 3: AMF sends a first perception service request message to SF, requesting to obtain the location information of the target UE, that is, requesting to execute the positioning perception service for the target UE.

[0387] Step 4: SF selects a sensing device (RAN / UE) with positioning sensing capabilities.

[0388] Step 5: SF determines the positioning perception mode according to the first perception service request message.

[0389] It should be noted that this example does not limit the order in which steps 4 and 5 are executed.

[0390] 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 to request positioning-related information of the target UE, for example, positioning measurement information (i.e., the value of the positioning measurement quantity) or positioning result (i.e., the location information of the target UE), that is, the second perception service request message is used to request the execution of the positioning perception service for the target UE.

[0391] Step 7: If the sensing devices selected by the SF include at least one UE, the SF sends a second sensing service request message to the UE to request positioning-related information of the target UE.

[0392] 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 perception device in at least one of steps 6 and 7, and feeds back the location information of the target UE to the AMF.

[0393] Step 9: 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, as shown in steps 9a to 9c in Figure 6b.

[0394] Example 3: Assisting in executing other sensing services based on UE location information.

[0395] For some perception services (i.e., the above-mentioned first perception service), the SF needs to perform a positioning perception service for the target UE to assist in the execution, wherein the above-mentioned positioning perception service and the first perception service can be executed simultaneously or sequentially. Specifically, the SF uses the location information of the target UE as the input of the first perception service to calculate the final result of the first perception service, or to improve the accuracy of the first perception service based on the location information of the target UE.

[0396] For example, in a scenario where a dual sensing device (for example, UE sends a sensing signal and RAN receives a sensing signal) is used to sense a target object, the location information of the sensing UE needs to be used as a reference point to accurately calculate the location information of the target object. In this scenario, the sensing function network element needs to perform a positioning sensing service for the UE to obtain the location information of the UE, and perform a 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 (sensing type) is the positioning (location / positioning) of the target UE; the other sensing type is other sensing services of the target object. Among them, the target UE will serve as one of the sensing devices of the other sensing service of the target object, and the location information of the target UE will serve as an input of the other sensing service of the target object.

[0397] The process of Example 3 is basically similar to that of Example 1, see FIG6c , except that:

[0398] In steps 1-3, the consumer and AMF can specify the sensing type including location and other in the process. The other can represent any sensing type different from positioning, which can be determined according to the type of the first sensing service. The following is an example of other representing sensing service type 1. However, the consumer and AMF can also specify only the sensing service type 1 to be performed, and the SF will subsequently decide whether to perform the positioning sensing service.

[0399] Optionally, in step 2b, if the AMF determines that the perception service type 1 requires assistance from the positioning perception service, the AMF may select a SF that supports both perception services.

[0400] Optionally, in step 3, the AMF may select a sensing device RAN / UE and send the sensing device information to the SF. The sensing device includes at least one of the following: a sensing device RAN2 and a target UE performing sensing service type 1, and a sensing device RAN1 and a target UE performing a positioning sensing service for the target UE. RAN1 and RAN2 may be the same or different.

[0401] Optionally, in step 4, the SF selects a sensing device RAN / UE, where the sensing device may include at least one of the following: a sensing device RAN2 performing sensing service type 1 and a target UE, and a sensing device RAN1 performing a positioning sensing service for the target UE and a target UE. RAN1 and RAN2 may be the same or different.

[0402] In step 5, the SF determines a sensing method corresponding to sensing service type 1. The sensing method includes but is not limited to: sensing service type 1 based on location service assistance of the sensing device target UE.

[0403] It should be noted that the above step 4 can be performed after step 5.

[0404] In 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 can be the same. Correspondingly, the SF obtains feedback information from the RAN, namely the third feedback information and the fourth feedback information.

[0405] 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 a target UE.

[0406] Correspondingly, the SF will obtain the feedback information of the UE, that is, the third feedback information and the fourth feedback information.

[0407] The other steps of Example 3 are similar to those of Example 1 and are not described here.

[0408] It should be noted that, in this example, the sensing devices for the positioning awareness service are RAN1 and target UE (the sensing object is the target UE in this case), and the sensing devices for the awareness service type 1 are RAN2 and target UE (the sensing object is the target object in this case). RAN1 and RAN2 may be the same or different. In addition, in steps 6 and 7 shown in FIG6c , the SF synchronously (in the same message) requires the RAN / UE to execute location and awareness service type 1 as an example. In some optional implementations, the SF may also trigger the two awareness services separately (in two message requests), that is, first require the RAN / UE to execute the positioning awareness service, and then request the RAN / UE to execute awareness service type 1, or first require the RAN / UE to execute awareness service type 1, and then request the RAN / UE to execute the positioning awareness service.

[0409] In summary, the embodiment of the present application utilizes a unified perception function network element to provide traditional UE positioning services, which is conducive to simplifying network function modules and avoiding problems such as too many function modules, complex interactions, and repeated functions.
