[0054] The method for establishing a perception service sharing channel provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0055] The sensing service shared channel establishment method provided in this application embodiment can be applied to sensing measurement data transmission scenarios. Under the instruction of the SF, the first RAN establishes a device-level sensing service shared channel. This sensing service shared channel does not correspond to only a certain sensing service, but can be used to transmit sensing measurement data of multiple sensing services between the SF and the first RAN. That is, the first RAN can transmit the sensing measurement data of multiple sensing services to the SF through this sensing service shared channel, overcoming the problem of redundant establishment of measurement data transmission channels for different sensing services in related technologies, saving network resources and improving network resource utilization.

[0056] Figure 3 This is one of the flowcharts illustrating the method for establishing a shared sensing service channel provided in this application embodiment, such as... Figure 3 As shown, the method includes steps 301-302; wherein:

[0057] Step 301: The first RAN receives a first sensing service establishment request message sent by the SF; wherein the first sensing service establishment request message includes the identification information corresponding to the SF.

[0058] Step 302: The first RAN responds to the first sensing service establishment request message and establishes a sensing service sharing channel; wherein, the sensing service sharing channel is used to transmit sensing measurement data of K sensing services between the SF and the first RAN; where K is a positive integer.

[0059] It should be noted that the embodiments of this application can be applied to sensing and measurement data transmission scenarios, and the connection relationship between the first RAN and SF can be referred to Figure 2 As shown, the SF sends a first sensing service establishment request message to the first RAN. The first sensing service establishment request message is used to instruct the first RAN to establish a sensing service shared channel between the SF and the first RAN. After receiving the first sensing service establishment request message sent by the SF, the first RAN establishes the sensing service shared channel.

[0060] In practice, the identification information corresponding to the SF can be used to distinguish or identify the shared sensing service channel. Specifically, the identification information corresponding to the SF is used to identify the endpoint of the SF in the shared sensing service channel between the first RAN and the SF. The identification information corresponding to the SF enables the first RAN to know the uplink destination SF for the sensing measurement data reporting. For example, the identification information corresponding to the SF may include: the SF's tunnel endpoint identification information (TEID), and / or the SF's IP address information.

[0061] It should be noted that the sensing service sharing channel between the SF and the first RAN in this embodiment is at the device level. The sensing service sharing channel does not correspond to a specific sensing service, and the first RAN does not need to establish separate measurement data transmission channels for different sensing services. This sensing service sharing channel can be used to transmit sensing measurement data of any sensing service between the SF and the first RAN. For sensing measurement data reported by the sensing measurement device received by the first RAN, the first RAN can send it to the SF through this sensing service sharing channel.

[0062] Optionally, the first sensing service establishment request message may include, in addition to the identification information corresponding to the SF, a list of sensing session IDs (SSIDs); wherein the SSID list includes L SSIDs, one SSID corresponding to one sensing service; and L is a positive integer. The SF establishes a sensing session for each sensing service, and different SSIDs are used to identify different sensing sessions. The SSID list includes L SSIDs specified by the SF, used to indicate to the first RAN the multiple SSIDs specifically served by the shared channel for the sensing service; the first RAN can perform exclusive data transmission according to the SSID list, that is, the first RAN uses the shared channel for the sensing service to support the transmission of sensing measurement data corresponding to the multiple SSIDs in the SSID list to the SF, but does not support the transmission of sensing measurement data corresponding to SSIDs not in the SSID list in the shared channel for the sensing service; the first RAN may discard sensing measurement data corresponding to SSIDs not in the SSID list when it receives them.

[0063] In the sensing service shared channel establishment method provided in this application embodiment, the first RAN establishes a device-level sensing service shared channel under the instruction of the SF. This sensing service shared channel does not correspond to only a certain sensing service, but can be used to transmit sensing measurement data of multiple sensing services between the SF and the first RAN. That is, the first RAN can transmit the sensing measurement data of multiple sensing services to the SF through this sensing service shared channel, which overcomes the problem of redundant establishment of measurement data transmission channels for different sensing services in related technologies, and can save network resources and improve network resource utilization.

[0064] Optionally, in response to the first sensing service establishment request message, after establishing a sensing service shared channel, the first RAN sends a first sensing service establishment response message to the SF; wherein, the first sensing service establishment response message is used to indicate whether the sensing service shared channel has been successfully established. The SF receives the first sensing service establishment response message sent by the first RAN.

[0065] Specifically, the first perception service establishment response message includes at least one of the following:

[0066] 1) Identification information corresponding to the first RAN;

[0067] 2) The first indication information is used to indicate whether the perception service sharing channel has been successfully established;

[0068] 3) Second indication information, used to indicate whether the sensing service is accepted or successfully executed by the sensing device serving the sensing service.

[0069] In practice, the identification information corresponding to the first RAN can be used to distinguish or identify the shared sensing service channel. Specifically, the identification information corresponding to the first RAN is used to identify the endpoint of the first RAN in the shared sensing service channel between the first RAN and the SF. Based on the identification information corresponding to the first RAN carried in the first sensing service establishment response message, the SF can obtain the first RAN that reported the sensing measurement data. For example, the identification information corresponding to the first RAN includes: the channel endpoint identification information of the first RAN, and / or the IP address information of the first RAN.

[0070] In practice, the second indication information can be specifically used to: indicate that a sensing device serving a sensing service has accepted or successfully executed a sensing service, and / or to indicate that a sensing device serving a sensing service has rejected or failed to execute a sensing service. The second indication information is obtained by the first RAN from the sensing signal measurement device and / or the sensing signal transmission device.

[0071] In this embodiment, after receiving a sensing service request message from a consumer device, the SF determines the sensing devices serving the sensing service and the first RAN for transmitting sensing measurement data for the sensing service based on the sensing service request message. The sensing devices include at least one of the following: 1) M sensing signal measurement devices; 2) N sensing signal transmitting devices; where M is a natural number and N is a natural number. Then, the SF sends the identification information of the M sensing signal measurement devices to the first RAN; correspondingly, the first RAN receives the identification information of the M sensing signal measurement devices sent by the SF.

[0072] In response to the first sensing service establishment request message, the first RAN establishes a sensing service shared channel and then triggers the establishment of a corresponding sensing measurement data transmission channel for each sensing signal measurement device. The sensing measurement data transmission channel establishment process may include:

[0073] 1) The first RAN sends a second sensing service establishment request message to each of the M sensing signal measurement devices; the second sensing service establishment request message is used to instruct each sensing signal measurement device to establish a sensing measurement data transmission channel with the first RAN.

[0074] 2) For any one of the M sensing signal measurement devices, taking sensing signal measurement device A as an example, after receiving the second sensing service establishment request message sent by the first RAN, sensing signal measurement device A establishes a sensing measurement data transmission channel; sensing signal measurement device A sends a second sensing service establishment response message to the first RAN; the second sensing service establishment response message is used to indicate whether the sensing measurement data transmission channel has been successfully established.

[0075] 3) The first RAN receives the second sensing service establishment response message sent by each sensing signal measurement device.

[0076] In practice, when the M sensing signal measurement devices include a sensing signal measurement UE, the sensing measurement data transmission channel established by the sensing signal measurement UE is the data radio bearer (DRB) corresponding to the sensing signal measurement UE; or,

[0077] When the M sensing signal measurement devices include a second RAN, the sensing measurement data transmission channel established by the second RAN is the channel of the interface between the second RAN and the first RAN (such as the Xn interface channel).

[0078] For example, if the sensing signal measurement device is a sensing UE, the first RAN triggers the establishment of an air interface data transmission channel (such as DRB) for each sensing UE, so that the sensing UE can send the sensing measurement data to the first RAN through the data transmission channel.

[0079] If the sensing signal measurement device is a sensing RAN, the first RAN triggers the establishment of a data transmission channel (such as an Xn interface channel) between each sensing RAN, so that the sensing RAN can subsequently send the sensing measurement data to the first RAN through this data transmission channel.

[0080] In this embodiment, the sensing signal measurement device receives a sensing service control message sent by the SF; wherein the sensing service control message includes the SSID corresponding to the sensing service; the sensing signal measurement device measures the sensing signal based on the sensing service control message to obtain the sensing measurement data of the sensing service. Then, the sensing signal measurement device sends the sensing measurement data of the sensing service and the SSID of the sensing session corresponding to the sensing service to the transmission RAN based on the sensing measurement data transmission channel.

[0081] After receiving the sensing measurement data of T sensing services sent by P sensing signal measurement devices, the first RAN sends the sensing measurement data of the T sensing services to the SF via the sensing service sharing channel; wherein P and T are both positive integers, P is less than or equal to M, and T is less than or equal to K.

[0082] Optionally, during the process of reporting sensing measurement data to the SF, the first RAN may simultaneously report the SSID corresponding to each of the sensing measurement data. The SSID corresponding to each of the sensing measurement data is used to identify the sensing service corresponding to each of the sensing measurement data. For example, the SSID corresponding to the sensing measurement data can be included as part of the data packet header information and sent to the RAN along with the sensing measurement data. Specifically, the first RAN determines the SSID corresponding to each of the sensing measurement data; the first RAN sends the SSID corresponding to each of the sensing measurement data to the SF via the sensing service sharing channel.

[0083] The implementation method for the first RAN to determine the SSID corresponding to each of the sensing measurement data includes any of the following:

[0084] 1) When the sensing signal measurement device sends sensing measurement data to the first RAN, it also sends the SSID corresponding to the sensing measurement data; the first RAN receives the SSID corresponding to each sensing measurement data sent by each of the P sensing signal measurement devices; then, the first RAN determines the SSID corresponding to each sensing measurement data.

[0085] 2) The first RAN stores the mapping relationship between the sensing signal measurement device ID / data transmission channel identifier and the sensing session; after the first RAN receives the sensing measurement data of T sensing services sent by P sensing signal measurement devices, it determines the SSID corresponding to each sensing measurement data based on the mapping relationship.

[0086] In practice, when a wireless communication system includes two or more SFs, if the first RAN establishes different sensing service sharing channels with different SFs, then after receiving sensing measurement data for T sensing services sent by P sensing signal measurement devices, the first RAN needs to determine the sensing service sharing channel used to transmit each sensing measurement data. In this embodiment, the first RAN specifically determines the SF serving the sensing service according to the identification information corresponding to the SF, and sends the sensing measurement data to the SF. Specifically, the first RAN determines the identification information corresponding to the SF corresponding to the SSID of each sensing measurement data based on the SSID of each sensing measurement data; the first RAN determines the SF serving the sensing service and the sensing service sharing channel according to the identification information of the SF, and sends the sensing measurement data to the SF.

[0087] Optionally, if the SF decides to modify the sensing service shared channel (for example, upon receiving a trigger message from a consumer device to add a sensing service or reduce an existing sensing service, the SF decides to update the SSID list corresponding to the sensing service shared channel), the SF may follow the same path as the sensing service shared channel and request the first RAN to modify the established sensing service shared channel, thereby serving one or more updated sensing services.

[0088] Specifically, the SF sends a sensing service modification request message to the first RAN; wherein the sensing service modification request message includes: identification information corresponding to the SF and / or identification information corresponding to the first RAN; the sensing service modification request message is used to instruct the first RAN to modify the sensing service shared channel between the SF and the first RAN. After receiving the sensing service modification request message sent by the SF, the first RAN modifies the sensing service shared channel; the first RAN sends a sensing service modification response message to the SF; wherein the sensing service modification response message is used to indicate whether the sensing service shared channel has been successfully modified. The SF receives the sensing service modification response message sent by the first RAN.

[0089] Optionally, when the SF decides to terminate the sensing service (which may be triggered by the consumer AF, or by setting a sensing service timer and the timer expires), the SF initiates the release of the sensing service shared channel established for the sensing service.

[0090] Specifically, the SF sends a sensing service deletion request message to the first RAN; wherein the sensing service deletion request message includes: the identification information corresponding to the SF and / or the identification information corresponding to the first RAN; the sensing service deletion request message is used to instruct the first RAN to delete the sensing service shared channel between the SF and the first RAN. After receiving the sensing service deletion request message sent by the SF, the first RAN deletes the sensing service shared channel; the first RAN sends a sensing service deletion response message to the SF; wherein the sensing service deletion response message is used to indicate whether the sensing service shared channel was successfully deleted. The SF receives the sensing service deletion response message sent by the first RAN.

[0091] Figure 4 This is the second flowchart illustrating the method for establishing a shared sensing service channel provided in this application embodiment, as shown below. Figure 4 As shown, the method includes:

[0092] Step 401: The SF sends a first sensing service establishment request message to the first RAN; wherein, the first sensing service establishment request message includes the identification information corresponding to the SF; the first sensing service establishment request message is used to instruct the first RAN to establish a sensing service sharing channel between the SF and the first RAN; the sensing service sharing channel is used to transmit sensing measurement data of K sensing services between the SF and the first RAN; where K is a positive integer.

[0093] It should be noted that the embodiments of this application can be applied to sensing and measurement data transmission scenarios, and the connection relationship between the first RAN and SF can be referred to Figure 2 As shown, the SF sends a first sensing service establishment request message to the first RAN. The first sensing service establishment request message is used to instruct the first RAN to establish a sensing service shared channel between the SF and the first RAN. After receiving the first sensing service establishment request message sent by the SF, the first RAN establishes the sensing service shared channel.

[0094] In practice, the identification information corresponding to the SF can be used to distinguish or identify the shared sensing service channel. Specifically, the identification information corresponding to the SF is used to identify the endpoint of the SF in the shared sensing service channel between the first RAN and the SF. The identification information corresponding to the SF enables the first RAN to know the uplink destination SF for the sensing measurement data reporting. For example, the identification information corresponding to the SF may include: the SF's tunnel endpoint identification information (TEID), and / or the SF's IP address information.

[0095] Optionally, for the explanation and clarification regarding the establishment of a shared sensing service channel in the first RAN, please refer to... Figure 3 The description of the illustrated embodiments will not be repeated here to avoid repetition.

[0096] In the sensing service shared channel establishment method provided in this application embodiment, the SF instructs the first RAN to establish a device-level sensing service shared channel. This sensing service shared channel does not correspond to only a certain sensing service, but can be used to transmit sensing measurement data of multiple sensing services between the SF and the first RAN. That is, the first RAN can transmit the sensing measurement data of multiple sensing services to the SF through this sensing service shared channel, which overcomes the problem of redundant establishment of measurement data transmission channels for different sensing services in related technologies, and can save network resources and improve network resource utilization.

[0097] Optionally, after the SF sends a first sensing service establishment request message to the first RAN, the SF receives a first sensing service establishment response message sent by the first RAN; wherein the first sensing service establishment response message is used to indicate whether the sensing service shared channel has been successfully established. In practice, the first sensing service establishment response message includes at least one of the following:

[0098] 1) Identification information corresponding to the first RAN; for example, the identification information corresponding to the first RAN includes: the channel endpoint identification information of the first RAN, and / or the IP address information of the first RAN.

[0099] 2) The first indication information is used to indicate whether the perception service sharing channel has been successfully established;

[0100] 3) Second indication information, used to indicate whether the sensing service is accepted or successfully executed by the sensing device serving the sensing service.

[0101] Optionally, the triggering condition for the SF to send the first sensing service establishment request message to the first RAN can be: the SF receives a sensing service request message sent by the consumer device. That is, the SF receives a sensing service request message sent by the consumer device; wherein, the sensing service request message includes information about the sensing object of the sensing service; and in response to the sensing service request message, the SF sends the first sensing service establishment request message to the first RAN.

[0102] In practice, the sensing service request message may include, in addition to information about the sensing object of the sensing service, sensing service description information; the sensing service description information is used to indicate the service characteristics of the sensing service; wherein, the sensing service description information includes at least one of the following:

[0103] 1) Perceive business type information;

[0104] Optionally, the perceived service type information is related to the perceived physical range and real-time requirements. For example, the perceived service type information includes: Type I, Type II, Type III, and Type IV; among them, Type I has a large perceived range and high real-time requirements (Delay Critical LSS); Type II has a large perceived range and low real-time requirements (LSS); Type III has a small perceived range and low real-time requirements (Delay Critical SSS); and Type IV has a small perceived range and low real-time requirements (SSS).

[0105] 2) Sensing quantity information; wherein the sensing quantity includes at least one of the following: the position of the sensing object, the distance of the sensing object, the moving speed of the sensing object, the imaging of the sensing object, the motion trajectory of the sensing object, the texture analysis information of the sensing object, and the material analysis information of the sensing object.

[0106] 3) Perceive information about business purpose or application use.

[0107] 4) Perceive business-level information;

[0108] Optionally, the perceived service granularity information may include: individual UE granularity, user group granularity, or region granularity.

[0109] 5) Sensing business time information, used to indicate the time information of sensing business execution.

[0110] 6) Sensing measurement data reporting information, used to indicate the conditions, reporting time, reporting format, and number of reporting times for sensing measurement data.

[0111] 7) Perceive service quality (QoS) information, also known as perceived metrics;

[0112] Optionally, the QoS information of the sensing service may include at least one of the following: sensing accuracy, sensing error, sensing range, sensing latency, detection probability, and false alarm probability; wherein, sensing accuracy includes: distance resolution, imaging resolution, moving speed resolution, or angular resolution; and sensing error includes: distance error, imaging error, or moving speed error.

[0113] 8) Sensing service range information, used to indicate the service range for performing sensing services on the sensing object. This service range can be a relative location range (e.g., within 20 meters of the sensing object) or an absolute location range. An absolute location range is, for example, one or more Tracking Area Indicators (TAIs), one or more cell IDs, or a specific geographic area identifier (e.g., a target square).

[0114] Understandably, the perceived object can be at the region granularity or the user granularity; that is, the perceived object can be an object region or an object user.

[0115] In this embodiment of the application, after the SF receives a sensing service request message sent by the consumer device, the SF determines the sensing device serving the sensing service based on the sensing service request message; wherein, the sensing device may include only M sensing signal measurement devices; and / or the sensing device may include N sensing signal transmitting devices; where M is a natural number and N is a natural number.

[0116] Optionally, the SF determines the first RAN for transmitting the sensing measurement data of the sensing service based on the sensing service request message. Specifically, the SF determines the first RAN for transmitting the sensing measurement data of the sensing service in any of the following ways:

[0117] 1) The SF determines the first RAN for transmitting the sensing measurement data of the sensing service based on the sensing object of the sensing service. The first RAN can serve the sensing object.

[0118] For example, the SF selects the first RAN for transmitting sensing measurement data, based on the object area or target service area (e.g., Area of ​​Interest, AOI) requested by the consumer equipment (e.g., AF) for the sensing service. The SF can obtain the RAN information serving the target service area from the network management equipment or the AMF.

[0119] For example, the SF determines the network location area where the sensing object is located based on the sensing object (i.e., the service object) of the sensing service provided by the consumer device, and then determines the first RAN serving the network location area for transmitting sensing measurement data based on the network location area. The SF can obtain the RAN information serving the network location area from the network management device or the AMF.

[0120] 2) The SF determines the first RAN for transmitting the sensing measurement data of the sensing service based on the sensing device of the sensing service, and the first RAN can serve the sensing device.

[0121] For example, the SF determines the RAN for transmitting sensing measurement data based on the identified sensing devices serving the sensing service. This data transmission RAN is responsible for the data transmission of these sensing devices. The SF can obtain the data transmission RAN information corresponding to the sensing devices from the network management device or the AMF.

[0122] In this embodiment, after receiving a sensing service request message from a consumer device, the SF establishes a sensing session corresponding to each sensing service based on the different sensing service request messages sent by each consumer device. Different sensing services correspond to different sensing sessions, and each sensing service corresponds to one sensing session. Specifically, the SF establishes a sensing session corresponding to the sensing service based on the sensing service request message and determines the SSID of the sensing session. The SF assigns a corresponding SSID to each sensing service, and different SSIDs are used to identify different sensing sessions. The SF performs data acquisition, analysis and processing, modification of sensing services, deletion of sensing services, and other operations based on the SSID.

[0123] Optionally, in the first sensing service establishment request message sent to the first RAN, the SF may include not only the identification information corresponding to the SF, but also a list of SSIDs; wherein, the list of SSIDs includes the SSIDs of the sensing sessions determined above; the list of SSIDs includes L SSIDs, one SSID corresponding to one sensing service; and L is a positive integer.

[0124] In this embodiment, after receiving a sensing service request message from a consumer device, the SF obtains QoS policy information for the sensing service based on the sensing service request message. The QoS policy information for the sensing service indicates the sensing service-related resources and sensing execution strategies allocated by the wireless communication network for the sensing service. Specifically, the implementation method of the SF obtaining the QoS policy information for the sensing service based on the sensing service request message may include:

[0125] Method 1: SF sends a policy request message to PCF; wherein, the policy request message is used to request the acquisition of QoS policy information of the sensing service; the policy request message includes at least one of the following: part or all of the sensing service description information, information of the sensing object of the sensing service (such as object area or object user), identification information of the sensing device, etc.

[0126] Method 2: SF generates QoS policy information suitable for sensing services.

[0127] In this embodiment, after the SF determines the SSID of the sensing session and / or the QoS policy information of the sensing service, the SF sends a sensing service control message to the sensing signal measurement device. Specifically, the SF sends sensing service control messages to M sensing signal measurement devices respectively; wherein, the sensing service control message includes the SSID of the sensing session, which is used to identify the sensing session corresponding to the sensing service. The SF and the sensing signal measurement devices perform sensing measurement data acquisition, analysis and processing, modification of sensing services, deletion of sensing services, etc., based on the SSID.

[0128] Optionally, in addition to the SSID of the sensing session, the sensing service control message may also include at least one of the following:

[0129] 1) Some or all of the QoS policy information of the perceived service;

[0130] 2) Perceive part or all of the business description information.

[0131] Specifically, the SF (Sensing Component) can instruct the sensing signal measurement equipment to measure the sensing signal according to the QoS policy information of the sensing service by carrying the QoS policy information of the sensing service in the sensing service control message. For example, the sensing UE / sensing RAN can perform corresponding measurement tasks according to the predetermined sensing accuracy based on the QoS parameters (such as sensing distance, angle, or intensity) indicated in the QoS policy information of the sensing service to obtain sensing measurement data.

[0132] Understandably, the SF can send a sensing service control message to the sensing signal measurement device via the first RAN; that is, the SF sends a sensing service control message to the first RAN; and the first RAN, after obtaining the information it needs (such as the identification information of M sensing signal measurement devices), forwards the sensing service control message to the sensing signal measurement device. Optionally, the SF sends the identification information of the M sensing signal measurement devices to the first RAN.

[0133] In this embodiment of the application, after the SF receives the sensing service request message sent from the consumer device, the SF sends a sensing resource configuration message to each of the N sensing signal transmitting devices; wherein, the sensing resource configuration message includes: the SSID of the sensing session corresponding to the sensing service, and the SSID is used to associate the sensing signal transmitting device with the sensing session.

[0134] The sensing resource configuration message is used to configure the sensing signal transmitting device according to the instructions in the sensing resource configuration information, so that the sensing signal transmitting device transmits sensing signals as instructed. Optionally, the sensing resource configuration message includes at least one of the following: spectrum, modulation method, and synchronization period. For example, the sensing signal transmitting device uses the spectrum indicated in the sensing resource configuration message to transmit sensing signals. Optionally, the sensing resource configuration message also includes part or all of the sensing service description information.

[0135] In this embodiment, after receiving the sensing service control message sent by the SF, the sensing signal measurement device measures the sensing signal based on the sensing service control message to obtain the sensing measurement data of the sensing service. Then, the sensing signal measurement device sends the sensing measurement data of the sensing service and the SSID of the sensing session corresponding to the sensing service to the transmission RAN based on the sensing measurement data transmission channel. After receiving the sensing measurement data of T sensing services sent by P sensing signal measurement devices, the first RAN sends the sensing measurement data of the T sensing services to the SF via the sensing service sharing channel; where P and T are both positive integers, P is less than or equal to M, and T is less than or equal to K. Optionally, during the process of reporting the sensing measurement data to the SF, the first RAN can simultaneously report the SSID corresponding to each of the sensing measurement data. The SSID corresponding to each of the sensing measurement data is used to identify the sensing service corresponding to each of the sensing measurement data; for example, the SSID corresponding to the sensing measurement data can be sent to the RAN as part of the data packet header information along with the sensing measurement data. Specifically, the first RAN determines the SSID corresponding to each of the sensing measurement data; the first RAN sends the SSID corresponding to each of the sensing measurement data to the SF via the sensing service sharing channel.

[0136] After receiving the sensing measurement data of T sensing services and the SSID corresponding to each sensing measurement data sent by the first RAN through the sensing service sharing channel, the SF classifies and associates each sensing measurement data based on the SSID corresponding to each sensing measurement data, so that the measurement data with the same SSID is grouped into one category, thus obtaining the sensing measurement data of the T sensing services, so that each category of data can be processed or forwarded to the consumer device corresponding to the sensing service.

[0137] Optionally, the SF obtains the perception service analysis result for each of the T perception services based on the perception measurement data of the T perception services. Specifically, the SF can perform corresponding calculations and analyses based on the algorithm configured internally for the perception service type corresponding to the SSID, thereby obtaining the perception service analysis result. For example, the perception service analysis result may be the user's respiratory health status information (whether it is abnormal, the degree of abnormality, etc.), or surrounding traffic hazard information (whether a pedestrian suddenly appears, the probability of appearance, the time), etc. It is understood that the algorithm for the perception service type corresponding to the SSID may be an AI-based intelligent algorithm, which may come from external intelligent entities or from AI model training.

[0138] Furthermore, the SF sends the sensing measurement data and / or sensing analysis results of each of the T sensing services to the corresponding consumer device of each sensing service.

[0139] Understandably, the SF can directly send the sensing measurement data of each of the T sensing services to the corresponding consumer device.

[0140] Figure 5 This is the third flowchart illustrating the method for establishing a shared sensing service channel provided in this application embodiment, as shown below. Figure 5 As shown, the method includes:

[0141] Step 501: The sensing signal measurement device receives a sensing service control message sent by the sensing network element SF; wherein, the sensing service control message includes the SSID of the sensing session corresponding to the sensing service;

[0142] Step 502: The sensing signal measurement device measures the sensing signal based on the sensing service control message to obtain the sensing measurement data of the sensing service.

[0143] Optionally, the sensing signal measurement device sends the sensing measurement data of the sensing service and the SSID corresponding to the sensing measurement data to the first RAN based on the sensing measurement data transmission channel.

[0144] After receiving the sensing measurement data of T sensing services sent by P sensing signal measurement devices, the first RAN sends the sensing measurement data of the T sensing services to the SF via the sensing service sharing channel; wherein P and T are both positive integers, P is less than or equal to M, and T is less than or equal to K.

[0145] In the method for establishing a shared channel for sensing services provided in this application embodiment, the SF sends a sensing service control message to the sensing signal measurement device, and the sensing service control message includes the SSID of the sensing session corresponding to the sensing service, instructing the sensing signal measurement device to perform sensing signal measurement for the sensing service.

[0146] In practice, after the first RAN responds to the first sensing service establishment request message and establishes a sensing service shared channel, it triggers the establishment of a corresponding sensing measurement data transmission channel for each sensing signal measurement device. Specifically, the first RAN sends a second sensing service establishment request message to each of the M sensing signal measurement devices; the second sensing service establishment request message instructs each sensing signal measurement device to establish a sensing measurement data transmission channel with the first RAN; after receiving the second sensing service establishment request message sent by the first access network device RAN, the sensing signal measurement device establishes the sensing measurement data transmission channel in response to the second sensing service establishment request message; the sensing signal measurement device then sends a second sensing service establishment response message to the first RAN.

[0147] Figure 6 This is a schematic diagram of the signaling flow of the perception service shared channel establishment method provided in the embodiments of this application, as shown below. Figure 6 As shown, the method includes:

[0148] Step 601: The consumer device initiates a sensing service request message to the SF; wherein, the sensing service request message includes information about the sensing object of the sensing service. The sensing service request message is used to request the SF to provide the sensing service.

[0149] Optionally, the method of sending the awareness service request message may include:

[0150] Method 1) See 601b, AF sends a sensing service request message to SF (with or without NEF);

[0151] Method 2) See 601a. ​​The AF first sends a sensing service request message to the AMF (with or without passing through the NEF), and then the AMF forwards the sensing service request message to the corresponding SF.

[0152] In this embodiment of the application, the consumer device may include: terminal device, third-party service function (AF), network-side device or network management device, etc.

[0153] Step 602: After receiving the sensing service request message sent by the consumer device, the SF determines the sensing device serving the sensing service and the first RAN for transmitting sensing measurement data based on the sensing service request message.

[0154] The sensing device includes M sensing signal measuring devices; or, the sensing device includes M sensing signal measuring devices and N sensing signal transmitting devices; where M is a natural number and N is a natural number.

[0155] Step 603: SF establishes a sensing session corresponding to the sensing service based on the sensing service request message, and determines the SSID of the sensing session.

[0156] Step 604: SF obtains QoS policy information for the sensing service based on the sensing service request message.

[0157] It should be noted that the execution order of steps 603 and 604 is not limited in the embodiments of this application. Step 603 may be executed before step 604, step 603 may be executed after step 604, or steps 603 and 604 may be executed simultaneously.

[0158] Step 605: SF sends a sensing service control message to the sensing signal measurement device.

[0159] Step 606: SF sends a sensing resource configuration message to each of the N sensing signal transmitting devices; the sensing signal transmitting devices send sensing signals; wherein, the sensing resource configuration message includes: the SSID of the sensing session corresponding to the sensing service.

[0160] Step 607: The SF sends a first sensing service establishment request message to the first RAN; the first sensing service establishment request message is used to instruct the first RAN to establish a sensing service sharing channel between the SF and the first RAN; the sensing service sharing channel is used to transmit sensing measurement data of K sensing services between the SF and the first RAN; K is a positive integer.

[0161] It should be noted that the messages in steps 605 and 607 can also be sent by the SF to the first RAN. After obtaining the necessary information cell information, the first RAN forwards the other information to the corresponding sensing signal measurement device. Specifically, the SF uses the same message to encapsulate different contents in different containers. For example, the SF encapsulates the contents involved in the aforementioned sensing service control message in the first container and forwards it to the sensing signal measurement device via the first RAN; while encapsulating the contents of the first sensing service establishment request message in the second container and sending it to the first RAN.

[0162] Additionally, the messages from steps 606 and 607 can also be sent by the SF to the first RAN. After obtaining the necessary information element information, the first RAN forwards the other information to the corresponding sensing signal transmitting device. Specifically, the SF uses the same message to encapsulate different content in different containers. For example, the SF encapsulates the content involved in the aforementioned sensing resource configuration message in the first container and forwards it to the sensing signal transmitting device via the first RAN; while encapsulating the content of the first sensing service establishment request message in the second container and sending it to the first RAN.

[0163] Optionally, K may represent the capacity of the sensing service shared channel.

[0164] In addition to instructing the first RAN to establish a shared sensing service channel and transmit sensing measurement data of K sensing services on the shared sensing service channel, the first sensing service establishment request message can also be used to modify the capacity of the shared sensing service channel. In other words, the first sensing service establishment request message can also be a first sensing service modification request message.

[0165] Before the sensing service sharing channel is established, the SF sends a first sensing service establishment request message to the first RAN. This first sensing service establishment request message is used to instruct the first RAN to establish a sensing service sharing channel, and the capacity of the sensing service sharing channel is K.

[0166] Once the shared sensing service channel is established, if the SF sends a first sensing service establishment request message to the first RAN again, the first RAN does not need to establish a shared sensing service channel again. Instead, it modifies the capacity of the shared sensing service channel. For example, regarding capacity, if X sensing services are added or Y sensing services are removed, the capacity of the shared sensing service channel is modified from K to K+X, or KY. That is, the shared sensing service channel is used to transmit sensing measurement data for (K+X) or (KY) sensing services between the SF and the first RAN.

[0167] Optionally, the first sensing service establishment request message may further include an SSID list; wherein the SSID list includes L SSIDs, and one SSID corresponds to one sensing service; and L is a positive integer.

[0168] Based on the above embodiments, when the SF sends a first sensing service establishment request message to the first RAN before the sensing service sharing channel is established, and the first sensing service establishment request message includes an SSID list consisting of L SSIDs, the first RAN establishes a sensing service sharing channel, and the sensing service sharing channel supports the L sensing services corresponding to the above L SSIDs.

[0169] When the SF sends a first sensing service establishment request message to the first RAN after the sensing service sharing channel is established, and the first sensing service establishment request message includes D SSIDs, the first RAN does not need to establish a sensing service sharing channel again. Instead, it modifies the sensing services supported by the sensing service sharing channel so that the sensing service sharing channel supports both the L sensing services corresponding to the L SSIDs and the D sensing services corresponding to the D SSIDs.

[0170] Step 608: After receiving the first sensing service establishment request message sent by the SF, the first RAN establishes a sensing service sharing channel; the sensing service sharing channel is used to transmit sensing measurement data of K sensing services between the SF and the first RAN; K is a positive integer.

[0171] Step 609: The first RAN triggers the establishment of a sensing measurement data transmission channel corresponding to the sensing service to each sensing signal measurement device.

[0172] Specifically, the first RAN sends a second sensing service establishment request message to each of the M sensing signal measurement devices; after receiving the second sensing service establishment request message sent by the first access network device RAN, the sensing signal measurement device establishes the sensing measurement data transmission channel; and the sensing signal measurement device sends a second sensing service establishment response message to the first RAN.

[0173] Optionally, when the SF sends a sensing service control message to the sensing signal measurement device via the first RAN, the first RAN can carry the sensing service control message in the second sensing service establishment request message, thereby forwarding the sensing service control message sent by the SF to the sensing signal measurement device.

[0174] Step 610: The first RAN sends a first sensing service establishment response message to the SF; wherein, the first sensing service establishment response message is used to indicate whether the sensing service shared channel has been successfully established.

[0175] Step 611: The sensing signal measurement device measures the sensing signal based on the sensing service control message to obtain the sensing measurement data of the sensing service.

[0176] Step 612: The sensing signal measurement device sends the sensing measurement data of the sensing service and the SSID corresponding to the sensing measurement data to the first RAN based on the sensing measurement data transmission channel.

[0177] Step 613: After receiving the sensing measurement data of T sensing services sent by P sensing signal measurement devices, the first RAN sends the sensing measurement data of the T sensing services to the SF via the sensing service sharing channel.

[0178] Step 614: After receiving the sensing measurement data of T sensing services sent by the first RAN through the sensing service sharing channel and the SSID corresponding to each sensing measurement data, the SF classifies and associates each sensing measurement data based on the SSID corresponding to each sensing measurement data.

[0179] Step 615: Based on the sensing measurement data of the T sensing services, SF obtains the sensing service analysis result of each of the T sensing services.

[0180] Step 616: SF sends the sensing measurement data and / or sensing analysis results of each of the T sensing services to the corresponding consumer device.

[0181] In this embodiment, the SF responds to sensing service request messages from different consumer devices and establishes a device-level shared channel between the SF and the first RAN to transmit all sensing measurement data related to sensing services. Regardless of which sensing service the sensing measurement data is for, it is reported to the SF through a unified channel, which can save network resources.

[0182] The sensing service shared channel establishment method provided in this application can be executed by a sensing service shared channel establishment device. This application uses the sensing service shared channel establishment device executing the sensing service shared channel establishment method as an example to illustrate the sensing service shared channel establishment device provided in this application.
