As shown in FIG. 2, an embodiment of this application provides a sensing device registration method, the method may be applied to the communication system as shown in FIG. 1, and the method may include step 201 as described below.

Step 201: A sensing UE sends sensing capability indication information of the sensing UE to a sensing RAN to make a network side device perform sensing device registration on the sensing UE.

The sensing capability indication information of the sensing UE may be used for indicating that the sensing UE has a sensing capability.

In the embodiment of this application, the sensing UE may send the above sensing capability indication information of the sensing UE to the sensing RAN, so that after the sensing RAN receives the sensing capability indication information of the sensing UE, the sensing RAN may send the sensing capability indication information of the sensing UE to an AMF. After the AMF receives the sensing capability indication information of the sensing UE, the AMF may determine whether the sensing UE is permitted to perform a sensing service. If the sensing UE is permitted to perform the sensing service, then the AMF may send first sensing device registration information to an SF so as to perform sensing device registration on the sensing UE, thereby making the network side device perform sensing device registration on the sensing UE.

Optionally, in the embodiment of this application, the sensing RAN may carry the sensing capability indication information of the sensing UE in an N2 message and send same to the AMF, thereby making the network side device perform sensing device registration on the sensing RAN.

Optionally, the sensing RAN may also carry the sensing capability indication information of the sensing RAN in the N2 message.

It should be noted that: the above sensing RAN may be a RAN serving the sensing UE. The RAN serving the sensing UE may be a sensing RAN, i.e., having a sensing capability, or may not have a sensing capability. The embodiment of this application is illustrated as an example of having a sensing capability. Optionally, if the RAN serving the sensing UE has a sensing capability, the sensing capability indication information of the RAN may be carried in the N2 message, and if the RAN serving the sensing UE does not have a sensing capability, the sensing capability indication information of the RAN will not be carried in the N2 message.

Optionally, in the embodiment of this application, the above sensing capability indication information may also be used for indicating a sensing capability which a sensing device (e.g., a sensing UE and/or a sensing RAN) has, and the sensing capability may include at least one of the following:

A: a sensing measurement method, the sensing measurement method of the sensing UE may include at least one of the following: the sensing UE sends a measurement signal and also receives the measurement signal to perform measurement, another UE sends a measurement signal and the sensing UE receives the measurement signal to perform measurement, the sensing RAN sends a measurement signal and the sensing UE receives the measurement signal to perform measurement, or the sensing UE sends a measurement signal and the sensing RAN receives the measurement signal to perform measurement. The sensing measurement method of the sensing RAN may include at least one of the following: the sensing RAN sends a measurement signal and also receives the measurement signal to perform measurement, another RAN sends a measurement signal and the sensing RAN receives the measurement signal to perform measurement, the sensing RAN sends a measurement signal and the sensing UE receives the measurement signal to perform measurement, or the sensing UE sends a measurement signal and the sensing RAN receives the measurement signal to perform measurement.

“Send” refers to sending a measurement signal, and “receive” refers to receiving the measurement signal to perform measurement.

B: A type of the sensing service, the type of the sensing service may include at least one of the following: a wide sensing range and a high real-time requirement; a wide sensing range and a low real-time requirement; a narrow sensing range and a high real-time requirement; or a narrow sensing range and a low real-time requirement;

Optionally, the above type of the sensing service may be indicated by numbers, letters or other character strings. The type of the sensing service may be determined according to the actual use requirements, which is not limited in the embodiment of this application.

C: A sensing purpose, the sensing purpose refers to an application scenario of the sensing device (e.g., a sensing UE and/or a sensing RAN) in the sensing service, and may include one or more scenarios supported by the sensing device that require the sensing service, such as respiration monitoring, monitoring of the surrounding traffic environment, and the like.

D: A sensing measurement signal, the sensing measurement signal is used to indicate a signal supported by the sensing device and used for sensing measurement. The signal may include at least one of the following: a reference signal received power (RSRP), reference signal received quality (RSRQ), a multipath angle of arrival, a multipath angle of departure, a multipath time delay, or a Doppler frequency.

E: A sensing measurement accuracy, the sensing measurement accuracy may include at least one of a sensing resolution or a sensing error.

Optionally, in the embodiment of this application, the above step 201 may be realized by step 201a or step 201b as described below.

Step 201a: The sensing UE sends a registration request message to the sensing RAN, the registration request message including sensing capability indication information.

The registration request message is a message indicating that the sensing UE requests to be registered to the network side device.

Step 201b: The sensing UE sends a radio resource control (RRC) message to the sensing RAN, the RRC message including the sensing capability indication information.

Optionally, the RRC message may also include a registration request message. Optionally, the registration request message may further include the above sensing capability indication information of the sensing UE.

In the embodiment of this application, after the sensing UE sends the above registration request message to the sensing RAN, the sensing RAN may forward the registration request message to the AMF, thereby making the sensing UE be registered to the network side device. After the AMF receives the registration request message, the AMF may send a registration acceptance message to the sensing RAN, and the sensing RAN may forward the registration acceptance message to the sensing UE, thereby making the sensing UE receive the registration acceptance message sent by the AMF.

It should be noted that: after step 201a or 201b, the AMF receives the sensing capability indication information of the sensing UE, then the AMF may learn that the sensing UE has a sensing capability. After step 201b, the RAN may learn that the sensing UE has a sensing capability.

Optionally, in the embodiment of this application, after the AMF receives the above sensing capability indication information of the sensing UE, the AMF may determine whether the sensing UE is permitted to perform the sensing service, and indicate whether the sensing UE is permitted to perform the sensing service by means of the above registration acceptance message.

It should be noted that: relevant description about how the AMF determines whether the sensing UE is permitted to perform the sensing service will be described in embodiments below and will not be described in detail herein.

Based on this, in the embodiment of this application, after the above step 201a, the sensing device registration method provided by the embodiment of this application may further include step 202 as described below.

Step 202: The sensing UE receives the registration acceptance message.

The registration acceptance message may include information indicating that the sensing UE is permitted to perform the sensing service.

Of course, during practical implementation, the above registration acceptance message may also include information indicating that the sensing UE is not permitted to perform the sensing service. If the sensing UE is not permitted to perform the sensing service, then the network side device will not perform sensing device registration on the sensing UE.

Optionally, the sensing device registration method provided by the embodiment of this application may further include step 203 as described below.

Step 203: The sensing UE sends sensing request indication information to the sensing RAN.

The above sensing request indication information may be used for requesting to use a sensing capability which the sensing UE has.

In one possible implementation, after the network side device receives the sensing capability indication information of the sensing UE and the sensing request indication information, if the sensing UE is permitted to perform the sensing service, then the network side device may perform sensing device registration on the sensing UE, i.e., the network side device executes a sensing device registration process of the sensing UE.

It can be understood that in the above implementation, if the network side device does not receive the above sensing request indication information, then the network side device may determine that the sensing UE is not expected to perform the sensing service, and thus the network side device may not perform sensing device registration on the sensing UE.

Optionally, in the embodiment of this application, the above sensing request indication information may be carried in the RRC message or the registration request message together with the sensing capability indication information of the sensing UE to be sent to the RAN. The RAN may carry the sensing request indication information together with the sensing capability indication information of the sensing UE in the N2 message to be sent to the AMF.

Optionally, in the embodiment of this application, after the network side device performs sensing device registration on the sensing UE, if it is required to execute the sensing service, then the network side device may send sensing configuration information of the sensing UE to the sensing UE, thereby making the sensing UE perform sensing measurement and report the corresponding sensing measurement result.

Based on this, the sensing device registration method provided by the embodiment of this application may further include steps 204-206 as described below.

Step 204: The sensing UE receives sensing configuration information of the sensing UE from the sensing RAN.

Step 205: The sensing UE performs, according to the sensing configuration information of the sensing UE, first sensing measurement to obtain a first sensing measurement result.

Step 206: The sensing UE reports the first sensing measurement result.

In the embodiment of this application, the sensing RAN may send the sensing configuration information of the sensing UE received from the network side device to the sensing UE, so that after the sensing UE receives the sensing configuration information, the sensing UE may perform the above first sensing measurement to obtain the above first sensing measurement result. The sensing UE may then report the first sensing measurement result to the network side device.

Optionally, in the embodiment of this application, the above sensing configuration information may include at least one of the following:

• • a sensing service correlation identifier (ID), where the sensing service correlation ID may be used to identify a session of a sensing service, and the sensing service ID may be assigned by the SF;
  • sensing service description information, where the sensing service description information may include a strategy which the SF formulates for the sensing service and control information, and may for example include at least one of the following: a sensing measurement method, a sensing service, a sensing purpose, a sensing measurement signal, or sensing measurement accuracy;
  • a sensing device ID, where the sensing device ID may be used to indicate a sensing device (e.g., a sensing UE and/or a sensing RAN) participating in sensing signal measurement optionally, the sensing device ID may include at least one of a sensing RAN ID or a sensing UE ID;
  • a sensing resource;
  • quality of service (QoS) registration information of the sensing service, where the QoS registration information of the sensing service may include at least one of a bandwidth configuration, a priority configuration, or an accuracy configuration;
  • a trigger condition for the sensing service; or
  • reporting information of sensing measurement.

Optionally, in the embodiment of this application, the sensing UE may report the above first sensing measurement result in different ways. In this way, the above step 206 may be realized by step 206a, step 206b or step 206c as described below.

Step 206a: The sensing UE sends a first message to the sensing RAN, where the first message carries the first sensing measurement result.

The first message may be a non-access stratum (NAS) message or an RRC message.

As a possible implementation, the above first message is a NAS message. The sensing UE may send the NAS message (carrying the first sensing measurement result) to the sensing RAN, and upon receipt of the NAS message by the sensing RAN, the NAS message may be carried in the N2 message and sent to the AMF, so that the AMF may forward the above first sensing measurement result to the SF. In this way, the first sensing measurement result obtained from the sensing measurement performed by the sensing UE is made to be reported to the network side device.

As a possible implementation, the above first message is an RRC message. The sensing UE may send the RRC message (carrying the first sensing measurement result) to the sensing RAN, and upon receipt of the RRC message by the sensing RAN, the sensing RAN may carry the first sensing measurement result in the RRC message in the N2 message to send same to the AMF, so that the AMF may forward the above first sensing measurement result to the SF. In this way, the first sensing measurement result obtained from the sensing measurement performed by the sensing UE is made to be reported to the network side device.

Optionally, when the sensing RAN sends the above first sensing measurement result to the AMF via the N2 message, the sensing RAN may also carry the sensing measurement result of the sensing RAN in the N2 message to report same to the AMF. The AMF may then forward the received sensing measurement result of the sensing UE and/or the sensing measurement result of the sensing RAN to the SF.

Step 206b: The sensing UE sends the first sensing measurement result to the sensing RAN via the first sensing tunnel.

The first sensing tunnel may be a sensing tunnel between the sensing UE and the sensing RAN.

In the embodiment of this application, the sensing UE may send the above first sensing measurement result to the sensing RAN via the above first sensing tunnel. After the RAN receives the first sensing measurement result, the RAN may send the first sensing measurement result to the SF.

It should be noted that: in the embodiment of this application, the sensing RAN may transmit messages/information/data to the SF via the AMF. In addition, the interaction mode between the sensing RAN and the SF will be described in detail in the following embodiments and will not be repeated here.

Optionally, in the embodiment of this application, before the above step 206b, the sensing device registration method provided by the embodiment of this application may further include step 207 and step 208 as described below.

Step 207: The sensing UE receives tunnel establishment parameters of the first sensing tunnel from the AMF.

Step 208: The sensing UE establishes, according to the tunnel establishment parameter of the first sensing tunnel, the first sensing tunnel.

The above first sensing tunnel is a sensing radio bearer, and the tunnel establishment parameters of the first sensing tunnel may be parameters of the sensing radio bearer.

Optionally, the tunnel establishment parameters of the first sensing tunnel may include at least one of a data network name (DNN), single network slice selection assistance information (S-NSSAI), or a QoS parameter.

Optionally, in the embodiment of this application, the AMF may carry the above parameters of the sensing radio bearer in the registration acceptance message to send same to the sensing RAN, and the sensing RAN then forwards same to the sensing UE. Thus, the sensing UE may establish, according to the parameters of the sensing radio bearer, the sensing radio bearer. In this way, after the UE obtains the above first sensing measurement result, the sensing UE may send the first sensing measurement result to the sensing RAN by means of the sensing radio bearer.

Step 206c: The sensing UE sends the first sensing measurement result to the SF via the second sensing tunnel.

The above second sensing tunnel may be a sensing tunnel between the sensing UE and the SF.

Optionally, in the embodiment of this application, before the above step 206c, the sensing device registration method provided by the embodiment of this application may further include step 209 and step 210 as described below.

Step 209: The sensing UE receives tunnel establishment parameters of the second sensing tunnel from the AMF.

Step 210: The sensing UE establishes, according to the tunnel establishment parameters of the second sensing tunnel, the second sensing tunnel.

The second sensing tunnel includes any one of the following: a sensing bearer and a sensing PDU session.

It can be understood that the above tunnel establishment parameters of the second sensing tunnel may be parameters of the sensing bearer or parameters of the sensing PDU session.

Optionally, the parameters of the sensing bearer or the parameters of the sensing PDU session may include at least one of a data network name (DNN), single network slice selection assistance information (S-NSSAI), a QoS parameter, or an address of the SF.

Optionally, in the embodiment of this application, the AMF may carry the above parameters of the sensing bearer or the parameters of the sensing PDU session (i.e., the tunnel establishment parameters of the second sensing tunnel) in the registration acceptance message to send same to the sensing RAN, and the sensing RAN then forwards same to the sensing UE. Thus, the sensing UE may establish, according to the parameters of the sensing bearer or the parameters of the sensing PDU session, the sensing bearer or the sensing PDU session. In this way, after the UE obtains the above first sensing measurement result, the sensing UE may send the first sensing measurement result to the SF via the sensing bearer or the sensing PDU session.

It is to be noted that, in the embodiment of this application, if the UE does not have the sensing capability, the UE will not send the sensing capability indication information to the RAN. If the RAN has the sensing capability, the RAN may still send the sensing capability indication information to the AMF via the N2 message in step 201, indicating that the RAN has the sensing capability. After receiving the sensing capability indication information of the RAN, the AMF may send the first sensing device registration information to the SF to register the sensing RAN into the SF, thereby making the network side device select a suitable sensing RAN to perform the sensing service when it is required to perform the sensing service.

In the embodiment of this application, since the sensing capability indication information is used to indicate that the sensing UE has a sensing capability, i.e., indicate that the sensing UE is a sensing device, after the sensing UE sends the sensing capability information to the sensing RAN, the network side device, in the case of determining that the sensing UE is a sensing device, can perform sensing device registration on the sensing UE, thereby, when it is required to perform the sensing service, the network side device can select a suitable sensing UE to perform the sensing service.

As shown in FIG. 3, an embodiment of this application provides a sensing device registration method, the method may be applied to the wireless communication system as shown in FIG. 1, and the method may include step 301 and step 302 as described below.

Step 301: An SF receives first sensing device registration information sent by a first device.

The above first sensing device registration information may be used to perform sensing device registration on a first sensing device, and the first sensing device may include at least one of a sensing UE or a sensing RAN.

It can be understood that the above first sensing device registration information may include at least one of the sensing device registration information of the sensing UE or the sensing device registration information of the sensing RAN.

Step 302: The SF performs, according to the first sensing device registration information, sensing device registration on the first sensing device.

In the embodiment of this application, after the SF receives the above first sensing device registration information, the SF may perform, according to the first sensing device registration information, sensing device registration on the first sensing device, so that the first sensing device can perform the sensing service after the sensing device registration is completed.

Optionally, in the embodiment of this application, the above first sensing device registration information may include at least one of the following:

• • an ID of the sensing UE;
  • a sensing capability of the sensing UE;
  • location information of the sensing UE;
  • an ID of the sensing RAN;
  • a sensing capability of the sensing RAN; or
  • location information of the sensing RAN.

It should be noted that: in the case that the above first sensing device includes the sensing UE, the first sensing device registration information may include at least one of the ID, the sensing capability and the location information of the sensing UE, or the ID, the sensing capability and the location information of the RAN serving the sensing UE. In the case where the first sensing device includes the sensing RAN, the first sensing device registration information may include at least one of the ID, the sensing capability or the location information of the sensing RAN.

Optionally, in the embodiment of this application, the ID of the sensing UE may include at least one of the following: an international mobile subscriber identity (IMSI), an international mobile equipment identification (IMEI), a media access control (MAC) address, a cell phone number, or a subscription concealed identifier (SUCI).

Optionally, in the embodiment of this application, the above location information may include at least one of the following: a tracking area identity (TAI), a cell identity, or a geographic location. Of course, during actual implementation, the location information may also include any other possible information, which may be determined according to the actual use requirements, and is not limited in the embodiment of this application.

Optionally, the sensing device registration method provided by the embodiment of this application may further include steps 303-305 as described below.

Step 303: The SF receives the sensing service information.

Optionally, in the embodiment of this application, the method of receiving the sensing service information by the SF may include two possible methods of realization, namely, method I and method II. The two methods are exemplarily described below, respectively.

Method I: An application function (AF) sends a sensing service request message to the SF. Optionally, the AF may send the sensing service request message to the SF via a network exposure function (NEF).

Method II: A consumer UE (i.e., a UE which expects the sensing service) directly sends the sensing service request message to the SF.

It should be noted that: in the embodiment of this application, the sensing service request message carries the description information of the sensing service (i.e., the above sensing service information), so that the SF can receive the sensing service information.

The step 306 may be realized by step 306b as described below.

Step 307: The SF establishes a third sensing tunnel between the SF the sensing RAN.

Step 306b: The SF receives the second sensing measurement result from the sensing RAN by means of the third sensing tunnel.

The above third sensing tunnel may be a Ny tunnel at the granularity of the UE.

The establishment request message of the third sensing tunnel may include an ID of the RAN on the N2 interface for identifying the UE. Optionally, an SF NyAP ID may also be included. Optionally, tunnel info on the SF side, namely, the SF Ny tunnel info, may also be included.

For example, the RAN sends an N2 message to the AMF, where the N2 message includes the sensing capability indication information of the UE. The sensing capability indication information of the UE may be included in the registration request message or may be transmitted in the N2 message together with the registration request message. Optionally, the RAN also includes the sensing capability indication information of the RAN in the N2 message. The sensing capability indication information of the RAN is used to indicate that the RAN is a RAN having a sensing capacity. Optionally, the sensing capability indication information of the RAN is further used to indicate the sensing capability which the RAN has, and for example, may include at least one of the following: a sensing measurement method, a type of a sensing service, a sensing purpose, a sensing measurement signal, or sensing measurement accuracy. The description of each of these items may refer to the description in 1a.

Optionally, step 1c, the AMF obtains subscription data of the UE from the UDM. The subscription data of the UE indicates whether the UE is capable of performing a sensing service. For example, the subscription data of the UE contains a sensing permission indication. The sensing permission indication indicates whether the UE can perform the sensing service. In this embodiment, example of permission is illustrated.

The AMF may determine, according to the subscription data of the UE and the local configuration, whether the UE is permitted to perform the sensing service.

Step 2: The UE receives a registration acceptance message from the AMF, where the registration acceptance message includes an indication about whether the UE is permitted to perform the sensing service. This embodiment is illustrated as an example of permission.

Optionally, the registration acceptance message may also include parameters for establishing a sensing PDU session or a sensing bearer, for example, at least one of a DNN, an S-NSSAI, a QoS parameter, or an address of the SF. It is to be noted that the AMF may send the PDU session parameters used by the sensing service to the UE during the UE registration process, or may send the sensing PDU session parameters or the sensing bearer parameters used by the sensing service to the UE after registration of the sensing UE. For example, by sending a UE configuration update message or a UE parameter update message, the PDU session parameters or the sensing bearer parameters used by the sensing service may be included in the UE policy (e.g., in the UE routing selecting policy URSP) in the UE configuration update message or the UE parameter update message.

Step 3: The AMF sends the sensing device registration information to the SF.

The sensing device registration information may include an ID of the sensing UE, and a sensing capability of the sensing UE. Optionally, location information of the sensing UE may also be included. The location information may be represented by at least one of the following: a TAI, a Cell ID, or a geographic location.

Optionally, the sensing device registration information may further include an ID of a RAN serving the sensing UE. Optionally, at least one of a sensing capability of the RAN serving the sensing UE or location information of the RAN serving the sensing UE may also be included.

Step 4: The SF acquires a sensing service request (i.e., the sensing service information).

Method I: the AF sends a sensing service request message to the SF, where the sensing service request message carries the description information of the sensing service. Optionally, the AF may send the sensing service request message to the SF via the NEF.

Method II: A consumer UE may also directly send the sensing service request message to the SF. The consumer UE points to the UE where the network requests the sensing service, and may also be a sensing UE or another UE.

Step 5: The SF determines, according to the received sensing service information, a sensing device participating in sensing signal measurement. The sensing device may include at least one of a sensing UE, a sensing UE and a RAN serving the sensing UE, or a sensing RAN.

Optionally, the SF may acquire the sensing device in a sensing service region from the AMF.

(I), The SF determines the sensing region according to the received sensing service information.

(II), The SF sends an event exposure service request message to the AMF, where the event exposure service request message includes the indication information of the sensing region.

(III)a, the SF receives an event exposure response message from the AMF, where the event exposure response message includes identification information of a sensing device located in the sensing region.

Or, (III)b, the SF receives an event exposure response message from the AMF, where the event exposure response message includes identification information of a sensing device that can provide sensing signal measurement of the sensing region.

Or, (III)c, the SF receives an event exposure response message from the AMF, where the event exposure response message includes identification information of a UE and/or a RAN located in the sensing region, and the SF determines, according to the sensing capability information of the UE and/or the RAN stored in the SF, a sensing device participating in sensing signal measurement.

The ID of the sensing device in the event exposure response message may be at least one of a sensing UE ID or a sensing RAN ID. The sensing UE ID includes identification information on the N2 interface for identifying the UE, such as at least one of a gNB NGAP ID or an AMF NGAP ID.

It should be noted that: step 5 may not have to be executed if the information required for the SF is included in step 3. For example, the ID of the sensing UE, the sensing capability of the sensing UE, the RAN to which the sensing UE is connected, and the location information of the sensing UE are included in step 3. Then step 5 may not need to be executed. If the SF considers that it is necessary to confirm or acquire some or all of the required information from the AMF, the SF executes step 5.

It should be noted that: the SF may obtain a plurality of sensing UE IDs and/or a plurality of sensing RAN IDs from the AMF. The SF may also determine, according to response of the AMF, a plurality of sensing UEs and/or sensing RANs to execute the sensing service. At this point, the later steps are executed for each sensing UE or each sensing RAN.

Step 6: The SF sends sensing configuration information to the AMF. The sensing configuration information is sensing configuration information that needs to be sent to the sensing UE via the AMF.

The sensing configuration information may include at least one of a Sensing service correlation ID, sensing service description information, or a sensing device ID.

The Sensing service correlation ID is used to identify a sensing service session, and the Sensing service correlation ID may be assigned by the SF.

The sensing device ID is used to indicate a sensing device participating in sensing signal measurement, and the sensing device may include a sensing UE and/or a sensing RAN. The sensing device ID may include at least one of a sensing RAN ID or a sensing UE ID.

The sensing service description information may include a strategy which the SF formulates for the sensing service description information and control information, and may for example include at least one of the following: a sensing measurement method, a sensing service, a sensing purpose, a sensing measurement signal, or sensing measurement accuracy.

The sensing configuration information may include at least one of sensing configuration information of the sensing UE or sensing configuration information of the sensing RAN.

Exemplarily, the SF may invoke a sensing configuration transfer service of the AMF, and the sensing configuration information is included in the sensing configuration transfer service to be sent to the AMF.

Step 7: The AMF sends an N2 message to the RAN, where the N2 message includes a NAS message of the sensing configuration information.

Step 8: The RAN forwards the above NAS message to the UE.

Step 9: The UE and/or the RAN executes sensing measurement. The UE and the RAN may perform the sensing measurement according to the received sensing configuration information.

Step 10: The UE sends a sensing measurement result to the SF.

Method I: The UE sends the NAS message to the AMF, where the NAS message includes the sensing measurement result of the UE. The RAN receives the NAS message and sends the N2 message to the AMF, where the N2 message includes the NAS message. Optionally, the sensing measurement result of the RAN may also be included. The AMF forwards the received sensing measurement result of the UE and/or the RAN to the SF.

Method II: The UE sends the RRC message to the RAN, where the NAS message includes the sensing measurement result of the UE. The RAN sends an N2 message to the AMF, where the N2 message includes the sensing measurement result of the UE. Optionally, the sensing measurement result of the RAN may also be included. The AMF forwards the received sensing measurement result of the UE and/or the RAN to the SF.

Method III: The UE sends the sensing measurement result of the UE to the SF via the sensing session or the sensing bearer. For example, as in step 2, if the UE obtains the sensing PDU session parameter or the sensing bearer parameter used by the sensing service, the UE may establish a sensing PDU session or a sensing bearer. The UE may use the sensing PDU session or the sensing bearer to send the sensing measurement result to the SF.

Example 2, the RAN registers the sensing device to the SF, as shown in FIG. 8:

Step 1: The UE sends a registration request message to the AMF, optionally where the registration request message may include sensing capability indication information of the UE. Reference may be made to the description of step 1a, step 1b, and step 1c in Example 1.

In addition, it should be noted that, optionally, the AMF may send an indication about whether the UE is permitted to perform the sensing service to the RAN at the same time as it sends a registration acceptance message to the RAN. Optionally, the AMF also sends the sensing capability of the UE to the RAN.

Step 2: The UE receives the registration acceptance message from the AMF, where the registration acceptance message includes an indication about whether the UE is permitted to perform the sensing service, and reference may be made to the description in Example 1.

Step 3: the RAN sends the sensing device registration information to the SF.

The sensing device registration information may include at least one of the following: identification information of the sensing device (e.g., when the sensing device is a UE, the identification information may be one of an IMSI, an IMEI, a MAC address, a cell phone number, a SUCI, a UE temporary ID, and an ID on the N2 interface for identifying the UE, and when the sensing device is a RAN, the identification information may be one of an FQDN, an ID and a MAC address), or a sensing capability of the sensing device. Optionally, location information of the sensing device may also be included. The sensing device may include at least one of a sensing UE or a sensing RAN.

The RAN may send the sensing device registration information via a protocol (e.g., the Next Generation Radio Sensing Protocol NRSPa protocol) between the RAN and the SF.

The registration information of the sensing UE and the registration information of the sensing RAN may be combined in a single message to be sent, or may be sent separately in different messages.

Optionally, in step 3a, the RAN may establish a Ny tunnel at the granularity of the UE with the SF. For example, when the RAN acquires the sensing capability of the sensing UE, it may send a NyAP establishment request to the SF, where the NyAP establishment request includes the registration information of the sensing UE. Optionally, the registration information of the sensing RAN may also be included.

The ID of the UE may include an ID assigned by the RAN for the UE on the Ny interface in addition to the above ID, and may be, for example, a RAN NyAP ID. Optionally, tunnel info on the RAN side, namely, the RAN Ny tunnel info, may also be included.

The SF receives a NyAP establishment request and sends a NyAP establishment response message to the RAN. The NyAP establishment response message includes the RAN NyAP ID, and optionally may also include an ID assigned by the SF for the UE, such as an SF NyAP ID. The SF NyAy ID may be the same as or different from the RAN NyAP ID. In the case that the SF NyAP ID may be the same as the RAN NyAP ID, it may appear only once in the NyAP establishment response message. Optionally, tunnel info on the SF side, namely, the SF Ny tunnel info, may also be included.

Optionally, the RAN may establish a Ny tunnel at the granularity of the UE with the SF via the AMF. That is, all messages in the above methods are transferred via the AMF.

When the Ny tunnel at the granularity of the UE between the RAN and the SF is established, it is required to carry the identification information of the UE on Ny for message interaction or data interaction between the RAN and the SF for the UE, such as at least one of the SF NyAP ID, the RAN NyAP ID, the RAN Ny tunnel info, or the SF Ny tunnel info.

The sensing configuration information may include sensing configuration information that needs to be sent to the sensing UE, optionally, the sensing configuration information of the RAN may also be included. The sensing configuration information may refer to the description in step 6 of Example 1.

Optionally, the SF may first perform an establishment process of the Ny tunnel at the granularity of the UE (6a). Exemplarily, after the SF determines the sensing device participating in the sensing signal measurement, the SF may trigger an establishment process of the Ny tunnel at the granularity of the UE if the sensing device includes a UE.

For example, a: The SF sends a NyAP establishment request message to the RAN, where the NyAP establishment request message includes an ID for the RAN to identify the UE on the N2 interface. Optionally, the SF NyAP ID may also be included. Optionally, tunnel info on the SF side, namely, the SF Ny tunnel info, may also be included.

b: The RAN determines, according to the ID for the RAN to identify the UE on the N2 interface, the UE. Optionally, the RAN assigns the RAN NyAP ID to the UE. The RAN NyAP ID uniquely identifies a UE in the RAN and used for identifying the UE on a Ny interface.

c: The RAN sends a NyAP establishment response message to the SF. The SF receives the NyAP establishment response message from the RAN, where the NyAP establishment response message includes at least one of the ID for the RAN to identify a UE on the N2 interface or the SF NyAP ID. Optionally, tunnel info on the RAN side, namely, the RAN Ny tunnel info, may also be included.

The SF NyAP ID may be the same as or different from the RAN NyAP ID. In the case that the SF NyAP ID may be the same as the RAN NyAP ID, it may appear only once in the NyAP establishment response message. The ID for the RAN to identify a UE on the N2 interface may be the same as or different from the SF NyAP ID.

As another possible way, the SF can establish a Ny tunnel at the granularity of the UE with the RAN via the AMF, i.e., all the messages in the above process are transferred via the AMF.

When the Ny tunnel at the granularity of the UE between the RAN and the SF is established, it is required to carry the identification information of the UE on Ny for message interaction or data interaction between the RAN and the SF for the UE, such as at least one of the SF NyAP ID, the RAN NyAP ID, the RAN Ny tunnel info, or the SF Ny tunnel info.

Step 3: The UE sends sensing device registration information to the SF via a sensing PDU session or a sensing bearer.

Optionally, 3a: The UE establishes the sensing PDU session or the sensing bearer. For example, if in step 2, the UE obtains the sensing PDU session parameters or the sensing bearer parameters used by the sensing service, the UE may establish the sensing PDU session or the sensing bearer. Exemplarily, the UE may send the sensing device registration information to the SF by means of the NRSP message.

Step 4: The SF acquires a sensing service request, which can refer to the description in Example 1.

Step 5: Optionally, the SF acquires the UE in the sensing service region from the AMF, which may refer to the description in Example 1.

Step 8: The UE sends a sensing measurement result to the SF via the sensing PDU session or the sensing bearer. Exemplarily, the UE may send the sensing measurement result to the SF using an NRSP message.

In Example 4, the UE establishes a sensing radio bearer and the RAN registers the sensing device to the SF, as shown in FIG. 10.

Step 1: The UE sends a registration request message to the AMF, where the registration request message includes the sensing capability indication information of the UE, which may refer to the description of step 1a, step 1b, and step 1c in Example 1. In particular, the UE may carry the sensing capability indication information of the UE in the RRC message.

Step 2: The UE receives the registration acceptance message from the AMF, where the registration acceptance message includes an indication about whether the UE is permitted to perform the sensing service, and reference may be made to the description in Example 1.

Step 8: The UE and/or the RAN executes sensing measurement, which may refer to the description in Example 1.

Step 9: The UE sends a sensing measurement results to the SF, which may refer to the description in Example 1.

In addition, the UE may also send the sensing measurement result to the SF in a possible method IV. The UE establishes a sensing radio bearer to send the sensing measurement result of the UE to the SF. For example, in step 2, if the UE obtains a sensing bearer parameter used by the sensing service, the UE may establish a sensing radio bearer. The UE may use the sensing radio bearer to send the sensing measurement result to the RAN. The RAN sends the sensing measurement result of the UE to the SF, and optionally the sensing measurement result of the RAN is further included. For example, the RAN may send the sensing measurement result to the SF via the NRSPa protocol, or via a Ny tunnel at the granularity of the UE.
