FIG. 2 is a schematic diagram of a sensing service process. As shown in FIG. 2, the sensing service process includes the following steps:

Step 0a: A service object (Consumer UE) transmits an application layer message to an AF, where the application layer message carries an ID of the service object and sensing service description information.

Step 1a: The AF triggers a sensing service request (There are two modes. In the first mode, the AF transmits a sensing service request message to a sensing control function (SCF) network element. In the second mode, the AF first transmits a sensing service request message to an AMF network clement and then the AMF network element forwards the sensing service request message to the SCF network element). Or,

Step 1b: The Consumer UE triggers the sensing service request (There are two implementation modes. In the first implementation mode, the Consumer UE directly transmits the sensing service request message to the SCF network element. In the second implementation mode, the Consumer UE first transmits the sensing service request message to the AMF network element, and then the AMF network element forwards the sensing service request message to the SCF network element).

It should be noted that step 1a and step 1b may both be an alternative relationship.

Step 2: The SCF network element transmits Namf_Communication_N1 N2 Message Transfer (sensing service message) to the AMF network element.

Step 3: The AMF network element transmits the sensing service message to a sensing UE.

The following three modes are included.

3
a: DL NAS TRANSPORT (Sensing service Message).

3
b: N2 TRANSPORT (Sensing service Message).

3
c: RRM configuration (sensing measurement control SSB/CSI).

Step 4: The sensing UE performs sensing measurement.

Step 5: The sensing UE reports a measurement result.

5
a: The sensing UE transmits a UL NAS TRANSPORT message (carrying a sensing data report) to the AMF network element.

Or,

5
b: The sensing UE transmits an RRC message (carrying a sensing data report) to a Sensing NG-RAN.

5
c: The Sensing NG-RAN transmits an N2 TRANSPORT message (carrying a sensing data report) to the AMF network element.

The sensing data report is generated according to a measurement result.

Step 6: The AMF network element transmits the sensing data report to the SCF network element through Namf_Communication_N1 N2 Message Transfer.

Step 7: The SCF network element calculates sensing data according to the sensing data report and obtains a sensing result.

Step 8: The SCF network element transmits the sensing data report or a sensing result report to the AF.

As can be seen from the above, FIG. 2 shows an overall sensing service process, but the following problems still exist in the sensing service scenario for a user granularity (a certain or a group of consumer UE):

Problem 1: Which network element (AMF or SCF) processes a sensing service request?

Problem 2: How to select a sensing control function network element or a sensing device for a sensing service of a mobile service object (mobile consumer UE)?

A sensing service processing method, a terminal, and a network-side device provided by embodiments of this application are described below in detail through some embodiments and application scenarios thereof with reference to the drawings.

FIG. 3 is a first schematic flowchart of a sensing service processing method according to an embodiment of this application. As shown in FIG. 3, an execution entity of the method is a first network element.

Optionally, the first network element involved in this embodiment of this application may be an access and mobility management function AMF network element or a sensing control function SCF network element.

It should be noted that the names of network elements involved in all embodiments of this application are merely illustrative and may be replaced by other names provided that similar functions are provided. For example, an SCF may be replaced by an SF (sensing function). In the following embodiments, a first network element is described as an AMF network element or an SCF network element, which is not limited to this application.

The method includes the following steps:

Step 300: A first network element receives a first sensing service request message, where the first sensing service request message is used for requesting for performing sensing for a service for a first user equipment.

The first user equipment UE may be an Internet of Things device, or a device used by a user, or the device used by the user refers to the user.

The sensing service is carried out for the first user equipment UE, which has the following meanings:

That is, a service object of the sensing service is the first UE, and the sensing service process is used for sensing and measuring one or more measurement quantities. The measurement quantity is associated with the first UE. This application has, but not limited to, the following situations:

The first UE may be a sensing signal measurer, which receives a signal transmitted by a peripheral. The first UE measures the measurement quantity. Or,

- the first UE may transmit a sensing signal, whereby the peripheral measures the sensing signal to obtain the measurement quantity.

Sensing signals are transmitted, received, and measured between other peripherals of the first UE, so as to evaluate the influence of signals passing through a surrounding environment of the first UE and acquire the measurement quantity associated with the first UE.

For example, the first UE refers to the user, and transmits a sensing physical signal using a transmitting device around the user. The physical signal passes through the environment around the user and is affected by the breathing of the user and reaches a signal receiving device. The signal receiving device performs analysis and measurement to acquire the measurement quantity of the sensing signal affected by the breathing of the user.

Step 301: The first network element selects a target sensing control function network element and/or a target sensing device according to location information of the first user equipment.

The target sensing control function network element includes a selected SCF network element. The target sensing device includes a selected sensing terminal device and/or sensing access network device.

The SCF network element may include at least one of the following functions:

- negotiating a sensing resource configuration with a sensing device (typically a signal transmitting device) such that the sensing device transmits a sensing physical signal according to configuration information or determines how the sensing device transmits the sensing physical signal;
- controlling the sensing device (typically a signal receiving device) to perform sensing measurement for a certain sensing service; or
- acquiring sensing measurement type information, and performing data analysis or data processing.

In this embodiment of this application, the sensing device includes a sensing terminal device (Sensing UE) and/or a sensing access network device (Sensing RAN).

The sensing device may include at least one of the following functions:

- negotiating a sensing resource configuration with the SCF network element;
- performing sensing measurement for a certain sensing service; or
- reporting a sensing measurement result (measurement value).

Optionally, the first network element determines location information of the first user equipment in response to the first sensing service request message, and selects a target sensing control function network element and/or a target sensing device according to the location information of the first user equipment and the first sensing service request message.

In this embodiment of this application, a first network element processes a sensing service request message, and the first network element selects a suitable sensing control function network element and/or sensing device for a sensing service of a first user equipment according to location information of the first user equipment, so as to ensure the smooth progress of a sensing service process based on a user granularity.

Optionally, the first sensing service request message is transmitted by the AF, or by the first user equipment, or by the AF through a network exposure function (NEF) network element.

In one implementation, before step 300, the method further includes the following steps:

Step 0: The consumer UE may interact with the AF in an application layer for sensing task information, where the sensing task information includes identification information of the consumer UE (such as a consumer UE ID or a Consumer UE IP address) and third sensing service description information.

Thus, the AF may determine that the consumer UE requests to execute a sensing service corresponding to the third sensing service description information.

Step 1a: The AF transmits a first sensing service request message to the first network element through the NEF network element.

If the AF belongs to an operator trusted AF, step la does not need to be performed by the NEF network element.

Step 1b: Optionally, the consumer UE may also directly transmit the first sensing service request message to the first network element.

In one implementation, the consumer UE may use an NAS message to transmit the first sensing service request message to the first network element.

Optionally, the first sensing service request message includes identification information of the first user equipment and first sensing service description information.

The first sensing service description information includes at least one of the following:

- sensing service type information;
- sensing object information;
- sensing measurement type information;
- sensing service purpose or application information;
- sensing service granularity information;
- sensing service time information;
- sensing data reporting information; or
- quality of service requirement information of sensing service.

It will be understood that the first sensing service request message carries the identification information of the first user equipment and the first sensing service description information.

Optionally, the first sensing service description information is the same or different from the third sensing service description information. In a case that the two pieces of information are different, the AF actually extracts or generates the first sensing service description information according to the third sensing service description information.

The identification information of the first user equipment refers to identification information of a service object of a sensing service, such as the consumer UE ID or the Consumer UE IP address, which is used for indicating a user equipment identifier triggering the sensing service, or explaining a user identifier corresponding to the service object of the sensing service.

The sensing service type information is used for defining a sensing service type, which may be defined according to a sensing physical range and real-time requirements, such as Type I: Large sensing range and high real-time requirement (e.g., Delay Critical Large Scale Service (LSS)); Type II: Large sensing range and low real-time requirement (e.g., LSS); Type III: Small sensing range and high real-time requirement (e.g., Delay Critical Small Scale Service (SSS)); Type IV: Small sensing range and low real-time requirement (e.g., SSS).

The sensing object information includes, but is not limited to, at least one of objects, equipment, people, animals, buildings, cars, environment, air quality, humidity, temperature, or a specific area (namely, a certain area).

The measurement type information is used for indicating which types of measurement quantities of a sensing object are measured, including but not limited to: at least one of a location of the sensing object, a distance of the sensing object, a moving speed of the sensing object, imaging of the sensing object, a motion trajectory of the sensing object, texture analysis and material analysis of the sensing object, a shape of the sensing object, or a heartbeat of the sensing object.

The sensing service granularity information includes, but is not limited to, a user granularity per UE or a user group granularity per UE Group. For example, the granularity information of the sensing service is the user granularity in this embodiment.

The sensing service time information may be used for defining time information about execution of a sensing service, which may be absolute time information (for example, Monday, 13:00-19:00) or relative time information (for example, within the next month). The time information may include a start time, an end time, a duration, or the like.

The sensing data reporting information is used for defining a reporting condition, a reporting time, a reporting format, and a reporting count of sensing data.

The reporting condition may be event triggering or periodic triggering. If the reporting condition is event triggering, the reporting condition further includes event description information (for example, determining that a user enters a driving state). If the reporting condition is periodic triggering, the reporting condition further includes reporting period information (for example, every 5 minutes). The reporting time is used for indicating a time range needed to report sensing measurement data, and the reporting time may be consistent or inconsistent with the foregoing sensing service time. In addition, the reporting format is used for indicating a form in which the sensing data is reported, for example, indicating reporting in a binary/text form. The reporting count is used for indicating whether the reporting is performed once or repeatedly, and indicating a count of repeated reporting.

The sensing service quality of service (QOS) requirement information includes, but is not limited to, at least one of a sensing accuracy, a sensing error, a sensing range, a sensing delay, a detection probability, or a false alarm probability. The sensing accuracy includes: a range resolution, an imaging resolution, a moving speed resolution, or an angle resolution. The sensing error includes: a range error, an imaging error, or a moving speed error.

In some optional embodiments, the first sensing service request message further includes: first sensing serving area information, where the first sensing serving area information includes absolute location range information or relative location range information corresponding to the first user equipment.

It should be noted that the first sensing serving area information is used for indicating a location range or location granularity of the sensing service for the service object of the sensing service.

The first sensing serving area information may be absolute location range information corresponding to the first user equipment. For example, the first sensing serving area information includes TAI(s), cell ID(s), and/or an area ID (such as Tiananmen Square, Beijing) corresponding to the first user equipment.

For example, when the granularity of a sensing service is TAI(s), it means that the sensing service is carried out within a range indicated by TAI(s). When the granularity of a sensing service is an area ID, it means that the sensing service is carried out within a range indicated by the area ID. In the presence of a plurality of pieces of information, a range indicated by the plurality of pieces of information may or may not be consistent. If no, it means that the sensing service is carried out within a union range of the ranges indicated by the plurality of pieces of information.

The first sensing serving area information may be relative location range information corresponding to the first user equipment. For example, the location of the first user equipment is within 20 meters around.

Optionally, the first sensing service request message carries the first sensing serving area information, indicating that the first sensing serving area information is designated by the AF or the first user equipment.

In some optional embodiments, the method further includes:

The first network element reselects the target sensing control function network element and/or the target sensing device according to an update of the location information of the first user equipment.

The location of the first user equipment may change continuously due to the movement thereof. Therefore, the first network element needs to track the location of the first user equipment all the time and reselect the target sensing control function network element and/or the target sensing device according to the update of the location information of the first user equipment.

Optionally, the first network element may subscribe the location information of the first user equipment to an RAN or to an LMF for tracking the location of the first user equipment.

For example, the AMF subscribes the location information of the consumer UE to the RAN or to the LMF for tracking the location of the consumer UE.

In some optional embodiments, as shown in FIG. 4, the first network element selects a target sensing control function network element and/or a target sensing device according to location information of the first user equipment, including:

Step 400: The first network element determines information of a first area according to the location information of the first user equipment and second sensing serving area information.

The second sensing serving area information includes relative location range information or absolute location range information associated with the first user equipment.

Optionally, the second sensing serving area information may be the first sensing serving area information, namely, relative location range information or absolute location range information associated with the first user equipment designated by the AF or the first user equipment. Or, the second sensing serving area information is generated according to the first sensing serving area information.

Optionally, the second sensing serving area information may also be default relative location range information or absolute location range information locally configured by the first network element.

Optionally, the location information of the first user equipment may be a TA, cell or another type of location of the first user equipment in the network.

Optionally, the first network element may also acquire the location information (such as GPS location information and grid location information) of the first user equipment from the LMF by using a network location service.

The first area refers to an area of interest (AOI).

The first network element determines information of a first area according to the location information of the first user equipment and second sensing serving area information by the following two implementation modes:

Mode 1: The first network element determines the AOI according to the location information of the first user equipment and the relative location range information or the absolute location range information locally configured by the first network element.

Mode 2: The first network element determines the AOI according to the location information of the first user equipment and the relative location range information or the absolute location range information associated with the first user equipment designated by the AF or the first user equipment.

Step 401: The first network element selects the target sensing control function network element and/or the target sensing device according to the information of the first area, where a serving area of the target sensing control function network element and/or the target sensing device includes the entire or partial first area.

The first network element needs to determine one or more target sensing control function network elements capable of serving the AOI and/or the target sensing device to carry out the sensing service.

The first network element determines whether the sensing control function network element and/or the sensing device can serve the AOI according to whether a serving area of the sensing control function network element and/or the sensing device includes the entire or partial AOI.

For example, if a serving area of an SCF includes an entire AOI, the SCF may serve the AOI, and the SCF may be used as a target sensing control function network element. If a serving area of an SCF includes a partial AOI, the SCF may serve the partial AOI (other parts of the AOI may be served by other SCFs), and the one or more SCFs may be used as target sensing control function network elements.

Optionally, the first network element further needs to select one or more sensing control function network elements and/or sensing devices that can satisfy, according to at least one information in the first sensing service request message, the information.

For example, the AMF further needs to select one or more SCFs satisfying the information based on at least one of the following information in the first sensing service request message:

- sensing service type information, where the SCF may, for example, provide a sensing control service corresponding to the sensing service type;
- sensing object information, where the SCF may, for example, serve the sensing object;
- sensing measurement type information, where the SCF may, for example, provide a sensing control service corresponding to the sensing measurement type;
- sensing service purpose or application information, where a sensing service provided by the SCF supports, for example, the purpose or application for the sensing service;
- sensing service granularity information, where the SCF may, for example, provide a sensing control service corresponding to the granularity;
- sensing service time information, where the SCF may, for example, provide a sensing control service for the sensing service time;
- sensing data reporting information, where the SCF, for example, supports reporting rules specified in the sensing data reporting information; or
- sensing service quality of service (QOS) requirement information, where a sensing service provided by the SCF enables, for example, the sensing service to meet the QoS requirement.

It should be noted that service sensing attribute and capability information of the SCF network element may be characterized by at least one of the following: supported sensing measurement range information, supported sensing service type information, supported sensing object information, supported sensing measurement type information, supported sensing service purpose or application information, supported sensing service time information, supported sensing data reporting information, or supported sensing service quality of service (QOS) information.

The first network element selects a sensing control function network element and/or a sensing device with reference to at least one information in the first sensing service request message by the following two implementations:

In one implementation, the first network element locally stores attribute and capability information of the sensing control function network element and/or the sensing device (for example, the sensing measurement range supported by the SCF, the sensing service type supported by the SCF, the sensing service Qos level supported by the SCF, and the like). Then the first network element selects the target sensing control function network element and/or the target sensing device according to the attribute and capability information of the sensing control function network element and/or the sensing device.

Optionally, the method further includes:

The first network element acquires service sensing capability information of a sensing control function network element and/or a sensing device in a network.

Optionally, the network herein may be the serving area of the first network element in the network or in the second sensing serving area or in the first area.

In the other implementation, the first network element selects the target sensing control function network element and/or the target sensing device according to the information of the first area, including:

The first network element queries the target sensing control function network clement and/or the target sensing device from a network repository function network element according to the information of the first area.

Optionally, the network repository function network element is an NRF network element. It should be noted that the NRF network element may also be replaced by other network elements with repository functions such as unified data management (UDM) and unified data repository (UDR). The NRF network element will be described below, which is not limited to this application.

A query request transmitted by the first network clement to the NRF carries corresponding query conditions. The query conditions may include at least one of the following: the information of the first area, or the service sensing attribute and capability information.

The service sensing attribute and capability information may be generated according to the sensing service description information.

It should be noted that the service sensing attribute and capability information is equivalent to the service sensing capability information in this application.

That is, the NRF returns the target sensing control function network element and/or the target sensing device to the first network element according to the query request. For example, the query conditions carry AOI and service sensing QoS capability information, and the NRF returns the target sensing control function network element and/or the target sensing device satisfying the query conditions. It should be noted that this mode is suitable for the sensing control function network clement and/or the sensing device registering own service sensing capability information in the NRF in advance.

Optionally, the first network element selects the target sensing control function network element and/or the target sensing device according to the information of the first area, including:

The sensing service capability matched with the sensing service refers to a capability of meeting the requirements of the sensing service, that is, a capability of executing the sensing service described by the first sensing service description information.

Optionally, the first network element selects the sensing control function network element/sensing device in the first area which can satisfy the sensing service corresponding to the first sensing service description information according to the service sensing capability information of the sensing control function network element/sensing device in the network.

Optionally, the first network element determines the service sensing capability information of the sensing control function network element/sensing device in the first area according to the service sensing capability information of the sensing control function network element/sensing device in the network, and selects the sensing control function network element/sensing device with the sensing service capability matched with the sensing service corresponding to the first sensing service description information.

Optionally, if the information of the first area changes, the first network element needs to reselect a sensing control function network element/sensing device in a new first area that can satisfy the sensing service corresponding to the first sensing service description information as the target sensing control function network element/sensing device.

Optionally, since a sensing terminal device (sensing UE) in the first area may leave the first area due to own movement, the first network element needs to continuously track and match the sensing terminal device (sensing UE) matched with the sensing service in the first area.

Optionally, the service sensing capability information includes at least one of the following:

FIG. 6 is a third schematic flowchart of a sensing service processing method according to an embodiment of this application. As shown in FIG. 6, an execution entity of the method is a sensing control function network element.

The method includes the following steps:

Step 600: A sensing control function network element receives a second sensing service request message.

The second sensing service request message includes: second sensing service description information and identification information of a target sensing device.

It should be noted that the sensing control function network element in this embodiment is the target sensing control function network element in the foregoing embodiments.

The target sensing control function network element receives the second sensing service request message transmitted by the first network element, obtains the second sensing service description information and the identification information of the target sensing device, and transmits sensing resource configuration information, a sensing measurement task, and sensing measurement control information to the target sensing device corresponding to the identification information, thereby ensuring the smooth progress of the sensing service process.

A signaling interaction flow of the sensing service processing method provided by this embodiment of this application is shown below.

FIG. 7 is a first schematic interaction flowchart of a sensing service processing method according to an embodiment of this application. The interaction flow includes the following steps:

Step 0: A service object (Consumer UE) transmits an application layer message to an AF, where the application layer message carries an ID of the service object and sensing service description information.

Step 1a: The AF transmits a sensing service request message to an AMF through an NEF, where sensing service description information is carried.

It should be noted that the sensing service description information in 1a may be the same as or different from that in step 0. In a case that the two pieces of information are different, the AF actually extracts or generates the corresponding sensing service description information in 1a according to the sensing service description information in step 0.

Optionally, the sensing service request message further includes identification information of a service object of a sensing service, such as the consumer UE ID or the Consumer UE IP address, which is used for indicating a user equipment identifier triggering the sensing service, or explaining a user identifier corresponding to the service object of the sensing service.

If the AF belongs to an operator trusted AF, step 1a does not need to be performed by the NEF.

Or,

Step 1b: The Consumer UE directly transmits the sensing service request message to the AMF.

The content of the sensing service request message in step 1b is similar to that in step 1a.

Step 1a and step 1b may both be an alternative relationship.

In one implementation, the consumer UE may use an NAS message to transmit the sensing service request message to the AMF.

Step 2: The AMF determines location information of the consumer UE and determines an AOI according to the location information.

It should be noted that in this embodiment of this application, the location of a service object (consumer UE) of a sensing service may change continuously due to the movement thereof. Therefore, the AMF needs to keep track of the location of the consumer UE and determine the corresponding AOI. The AMF may subscribe the location of the consumer UE to an RAN or to an LMF for tracking the location of the consumer UE.

Step 3: The AMF selects a sensing control function SCF network element according to the AOI.

Step 4: The AMF interacts service sensing capability information with a sensing device in a network.

The sensing device in the network here includes a sensing UE and/or a sensing RAN within an AMF serving area.

Trigger scenarios where the sensing UE reports own service sensing capability information to the AMF include but are not limited to at least one of the following:

- initially entering the AMF serving area (initial registration);
- the sensing UE performs mobility registration in the AMF serving area;
- a sensing service capability of the sensing UE changes; or
- the AMF/SF/RAN issues a service sensing capability information acquisition request to the sensing UE.

The service sensing capability information reported to the AMF by the sensing UE includes but is not limited to at least one of the following:

- sensing service measurement supported or not, for example, supported or not supported;
- measurement-supported sensing service type information, for example, type I, type II, and the like;
- supported sensing object information, for example, air, buildings, human bodies, or the like;
- supported sensing measurement range information, for example, absolute range (such as TA list or cell ID list) or relative range (100 meters around sensing UE);
- supported sensing measurement type information, for example, the shape of the sensing object, the heartbeat of the sensing object, the speed of the sensing object, and the like;
- supported sensing service quality of service (QOS) information, where the sensing QoS includes, for example but is not limited to, at least one of a sensing accuracy, a sensing error, a sensing range, a sensing delay, a detection probability, or a false alarm probability, the sensing accuracy includes: a range resolution, an imaging resolution, a moving speed resolution, or an angle resolution, and the sensing error includes: a range error, an imaging error, or a moving speed error;
- supported sensing measurement service purpose or application information, for example, air quality detection, intelligent transportation, and the like;
- supported sensing measurement time information, for example, 07:00 to 10:00 every day available and 22:00 to 24:00 every Monday unavailable; and
- supported sensing data reporting information, for example, supported periodic reporting and/or event-triggered reporting, and supported data reporting formats.

Trigger scenarios where the Sensing RAN reports own service sensing capability information to the AMF include but are not limited to at least one of the following:

- the Sensing RAN establishes a device-to-device connection with the AMF;
- the Sensing RAN establishes a user granularity connection with the AMF;
- a capability of the Sensing RAN changes; or
- the AMF/SF actively acquires service sensing capability information from the sensing RAN.

The service sensing capability information reported by the sensing RAN to the AMF is similar to the above service sensing capability information of the sensing UE and will not be repeated herein.

Step 5: The AMF selects the sensing UE/RAN in the AOI as the target sensing measurement device of the sensing service according to the sensing service request message and the capability information of the sensing UE/RAN.

In addition, the sensing UE(s) in the AOI may change continuously due to own mobility. Therefore, the AMF needs to continuously track and match the sensing UE in the AOI matched with the sensing service. And the SCF is notified of a new sensing UE, whereby the SCF issues the sensing service control information to the new sensing UE.

Step 6: The AMF forwards the sensing service request message to the SCF network element selected in step 3, where the sensing service request message carries the sensing service description information and the identification information of the selected sensing device (sensing UE/RAN).

The sensing service description information transmitted here is generated by the AMF according to the sensing service description information received from the AF, and the two pieces of information may be the same or different.

After the above steps, the AMF selects a suitable SCF for the sensing service of the consumer UE, and selects the sensing device. Then the AMF transmits an identifier of the sensing device to the SCF, whereby the SCF transmits sensing resource configuration information, a sensing measurement task, and sensing measurement control information to the sensing device subsequently, thereby ensuring the smooth progress of the sensing service process.

FIG. 8 is a second schematic interaction flowchart of a sensing service processing method according to an embodiment of this application. The interaction flow includes the following steps:

Steps 1-3 are the same as steps 1-3 in FIG. 7, and will not be repeated herein.

Step 4: The AMF forwards a sensing service request message to the SCF, where the sensing service request message carries at least one of the following: second sensing service description information; information of a first area (AOI); or identification information of a candidate sensing device in the first area.

Step 5: The SCF and the sensing UE/RAN in the network interact in terms of service sensing capability information.

The sensing UE/RAN in the network may be all sensing UE/RANs in the entire network, or sensing UE/RANs in the partial network. The partial network may be limited to the AOI range acquired in step 4 or may not be limited thereto.

Optionally, the partial network may be a serving area of the SCF. In other words, the SCF and the sensing UE/RAN within the sensing area may interact in terms of service sensing capability information.

In one implementation, trigger scenarios where the sensing UE reports own service sensing capability information to the SCF include but are not limited to at least one of the following:

- initially entering a serving area of the SCF;
- the Sensing UE establishes a device-to-device connection with the SCF;
- the sensing UE periodically updates a sensing service capability in the serving area of the SCF;
- a sensing service capability of the sensing UE changes; or
- the AMF/SF/RAN issues a service sensing capability information acquisition request to the sensing UE.

The Sensing UE reports the service sensing capability information to the SCF similar to that described in step 4 of FIG. 7.

Trigger scenarios where the Sensing RAN reports own service sensing capability information to the SCF include but are not limited to at least one of the following:

- the Sensing RAN establishes a device-to-device connection with the SCF;
- the Sensing RAN establishes a user granularity connection with the SCF;

- the AMF/SF actively acquires service sensing capability information from the sensing RAN.

The service sensing capability information reported by the sensing RAN to the SCF is similar to the service sensing capability information of the sensing UE in the foregoing embodiments and will not be repeated herein.

After the above steps, the AMF selects a suitable SCF for the sensing service of the consumer UE, and the SCF selects the sensing device, whereby the SCF transmits sensing resource configuration information, a sensing measurement task, and sensing measurement control information to the sensing device subsequently, thereby ensuring the smooth progress of the sensing service process.

FIG. 9 is a fourth schematic flowchart of a sensing service processing method according to an embodiment of this application. As shown in FIG. 9, an execution entity of the method is a sensing control function network element.

The method includes the following steps:

Step 900: A sensing control function SCF network element receives a first sensing service request message, where the first sensing service request message is used for requesting for performing sensing for a service for a first user equipment.

The first user equipment UE may be an Internet of Things device, or a device used by a user, or the device used by the user refers to the user.

The sensing service is carried out for the first user equipment UE, which has the following meanings:

That is, a service object of the sensing service is the first UE, and the sensing service process is used for sensing and measuring a certain measurement quantity. The measurement quantity is associated with the first UE. This application has, but not limited to, the following situations:

The first UE may be a sensing signal measurer, which receives a signal transmitted by a peripheral. The first UE measures the measurement quantity. Or,

- the first UE may transmit a sensing signal, whereby the peripheral measures the sensing signal to obtain the measurement quantity.

For example, the first UE refers to the user, and transmits a sensing physical signal using a transmitting device around the user. The physical signal passes through the environment around the user and is affected by the breathing of the user, and reaches a signal receiving device. The signal receiving device performs analysis and measurement to acquire the measurement quantity of the sensing signal affected by the breathing of the user.

Optionally, the first sensing service request message is transmitted by the AF, or by the first user equipment, or by the AF through a network exposure function (NEF) network element.

In one implementation, before step 900, the method further includes the following steps:

Thus, the AF may determine that the consumer UE requests to execute a sensing service corresponding to the third sensing service description information.

Step 1a: The AF transmits a first sensing service request message to the SCF network element through the NEF network element.

If the AF belongs to an operator trusted AF, step 1a does not need to be performed by the NEF network element.

Step 1b: Optionally, the consumer UE may also directly transmit the first sensing service request message to the SCF network element.

In one implementation, the consumer UE may use an NAS message to transmit the first sensing service request message to the SCF network element.

Optionally, the first sensing service request message includes: identification information of the first user equipment and first sensing service description information.

The first sensing service description information includes at least one of the following:

- sensing service type information;
- sensing object information;
- sensing measurement type information;
- sensing service purpose or application information;
- sensing service granularity information;
- sensing service time information;
- sensing data reporting information; or
- quality of service requirement information of sensing service.

The identification information of the first user equipment and the first sensing service description information may be described with reference to the description in the foregoing embodiments and will not be repeated herein.

Optionally, the first sensing service request message further includes: first sensing serving area information, where the first sensing serving area information includes absolute location range information or relative location range information corresponding to the first user equipment.

The first sensing serving area information may be understood with reference to the description in the foregoing embodiments and will not be repeated herein.

Step 901: The sensing control function network element transmits a first request message to a first network element, where the first request message is used for requesting to acquire identification information of a sensing device in a sensing serving area corresponding to the first user equipment.

Optionally, the sensing serving area corresponding to the first user equipment includes absolute location range information or relative location range information corresponding to the first user equipment.

The sensing serving area corresponding to the first user equipment is represented by third sensing serving area information.

In a case that the first sensing service request message received by the sensing control function network element carries the first sensing serving area information, the third sensing serving area information is the same as or different from the first sensing serving area information. In a case that the two pieces of information are different, the third sensing serving area information is generated by the sensing control function network element according to the first sensing serving area information.

Optionally, the third sensing serving area information may be carried in a first request message and transmitted to a first network element (such as an AMF network element) through the first request message. That is, the first request message includes: identification information (such as a consumer UE ID or a Consumer UE IP address) of the first user equipment and the third sensing serving area information.

Optionally, the first request message may be Namf_EventExposure_Subscribe.

Or, the third sensing serving area information is configured locally in the first network element, and neither the first sensing service request message nor the first request message carries the information.

In one implementation, the sensing serving area of the consumer UE may be a relative range (such as within 20 meters of the periphery centered by the consumer UE). The relative range may be carried in the first request message or configured in the AMF by default. In this case, the first request message is used for requesting the AMF to detect a UE ID list and/or an RAN ID list within the relative range of the consumer UE.

In another implementation, the sensing serving area of the consumer UE may be an absolute range (such as Tiananmen Square), and the absolute range information is carried in the first request message for instructing the AMF to provide the UE list and/or the RAN list within the absolute range at the same time when detecting the occurrence of an event that the consumer UE enters the absolute range.

Optionally, the first network element includes an access and mobility management function AMF network element. Or,

- the sensing device includes a sensing terminal device (sensing UE) and/or a sensing access network device (sensing RAN).

Step 902: The sensing control function network element receives a first request response message transmitted by the first network element, and acquires identification information of a candidate sensing device in the sensing serving area corresponding to the first user equipment.

After receiving the first request message, the first network element determines the information of the first area according to the location information of the first user equipment and the sensing serving area corresponding to the first user equipment, and acquires the identification information of the candidate sensing device in the first area.

The identification information of the candidate sensing device includes identification information of one or more candidate sensing devices.

Here, the candidate sensing device in the first area may be all UE ID lists and/or RAN ID lists in the first area identified by the first network element. Or,

the candidate sensing device in the first area may be UE ID lists and/or RAN ID lists for carrying out sensing services in the first area identified by the first network element.

The first network element transmits the identification information of the candidate sensing device in the sensing serving area corresponding to the first user equipment to the sensing control function network element through the first request response message.

For example, the AMF determines an AOI according to the location information of the consumer UE and the first sensing serving area information, and the AMF determines a UE ID list and/or an RAN ID list within the AOI. The AMF transmits the UE ID list and/or the RAN ID list within the AOI to the SCF.

Optionally, the AMF may transmit the UE ID list and/or the RAN ID list using a Namf_EventExposure_Notify message.

It should be noted that the location of the first user equipment may change continuously due to the movement thereof. Therefore, the first network element needs to track the location information of the first user equipment all the time, whereby the first area will change, and the identification information of the candidate sensing device in the sensing serving area corresponding to the first user equipment determined by the first network element changes accordingly.

In addition, since a sensing terminal device (sensing UE) in the first area may leave the first area due to own movement, the first network element also needs to continuously track and determine identification information of a candidate sensing terminal device in the sensing serving area corresponding to the first user equipment.

Step 903: The sensing control function network element selects a target sensing device for the sensing service according to the identification information of the candidate sensing device.

Optionally, the method further includes:

The sensing control function network element acquires service sensing capability information of a sensing device in a network.

The network here may be the entire or partial network. The partial network may be limited to the first area or may not be limited thereto.

Optionally, the partial network may be a serving area of the sensing control function SCF network element. That is, the SCF and the sensing UE/RAN within the sensing area may interact in terms of service sensing capability information.

Optionally, the sensing control function network element selects a target sensing device for the sensing service according to the identification information of the candidate sensing device, including:

The sensing control function network element selects a sensing device with a sensing service capability matching the sensing service in the candidate sensing device as the target sensing device according to the service sensing capability information of the sensing device in the network.

For example, the SCF network element selects sensing UE(s) with a sensing service network capability satisfying the sensing service from the candidate UE ID list, and/or the SCF network element selects sensing RAN(s) with a sensing service capability satisfying the sensing service from the candidate RAN ID list.

Optionally, the service sensing capability information includes at least one of the following:

In this embodiment, user equipment or AF triggers to transmit a sensing service request message. After receiving the sensing service request message, the sensing control function SCF network element transmits identification information of a sensing device in a sensing serving area corresponding to a first user equipment to the first network element, and selects a target sensing device for the sensing service according to the identification information, whereby the sensing control function SCF network element transmits sensing resource configuration information, a sensing measurement task, and sensing measurement control information to the target sensing device subsequently, thereby ensuring the smooth progress of a sensing service process.

As shown in FIG. 10, an execution entity of the method is a first network element. Optionally, the first network element includes: an access and mobility management function AMF network element.

Optionally, the determining information of a first area according to location information of the first user equipment includes:

- determining the information of the first area according to the location information of the first user equipment and the third sensing serving area information.

For example, the AMF determines an AOI according to the location information of the consumer UE and the third sensing serving area information, and the AMF determines a UE ID list and/or an RAN ID list within the AOI. The AMF transmits the UE ID list and/or the RAN ID list within the AOI to the SCF.

Optionally, the AMF may transmit the UE ID list and/or the RAN ID list using a Namf_EventExposure_Notify message.

In this embodiment, user equipment or AF triggers to transmit a sensing service request message. After receiving the sensing service request message, the sensing control function SCF network element transmits identification information of a sensing device in a sensing serving area corresponding to a first user equipment to the first network element. After receiving the request, the first network element returns the identification information of the sensing device in the sensing serving area corresponding to the first user equipment, whereby the SCF network element selects a target sensing device for the sensing service according to the identification information, and the sensing control function SCF network element transmits sensing resource configuration information, a sensing measurement task, and sensing measurement control information to the target sensing device subsequently, thereby ensuring the smooth progress of a sensing service process.

FIG. 11 is a third schematic interaction flowchart of a sensing service processing method according to an embodiment of this application. As shown in FIG. 11, the interaction flow includes the following steps:

Step 1a: The AF transmits a sensing service request message to an SCF network through an NEF network element, where sensing service description information is carried.

If the AF belongs to an operator trusted AF, step 1a does not need to be performed by the NEF.

Or,

Step 1b: The Consumer UE directly transmits the sensing service request message to the SCF.

The content of the sensing service request message in step 1b is similar to that in step 1a.

Step 2: The SCF transmits a first request message to an AMF, where the first request message is used for requesting to acquire identification information of a sensing device in a sensing serving area corresponding to a first user equipment.

Step 3: The AMF determines an AOI according to the location of a consumer UE and a serving area of a sensing service of the consumer UE, and the AMF determines identification information (UE ID list and/or RAN ID list) of a sensing device in the AOI.

Step 4: The AMF transmits the identification information (UE ID list and/or RAN ID list) of the sensing device determined in step 3 to the SCF.
