It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.

[0037] Based on the aforementioned wireless communication system, such as Figure 1b As shown, this application also provides a network architecture for a sensing service system, which includes multiple UEs, a Radio Access Network Equipment (RAN), an Access and Mobility Management Function (AMF), a User Plane Function (UPF), a first network element, a Network Exposure Function (NEF), and consumer equipment. Among them:

[0038] The plurality of UEs can be sensing signal measurement devices or sensing signal transmission devices, and there is no limitation on this.

[0039] The RAN can function as a transmission node, as well as a sensing signal measurement device or a sensing signal transmission device. It should be noted that the sensing service system can simultaneously include one or more sensing signal transmission devices and one or more sensing signal measurement devices corresponding to a sensing service.

[0040] The first network element is a network element introduced to support sensing services. That is, the first network element can be understood as a sensing network element (SF).

[0041] In this application, the first network element and the sensing device (including sensing signal transmitting device and sensing signal measuring device) can directly or indirectly interact with the signaling and / or sensing service data corresponding to the sensing service.

[0042] In addition, the first network element can also perform corresponding data processing or analysis on the acquired sensing service data (such as sensing measurement data) to provide sensing service processing results or sensing service analysis results to consumers of sensing services.

[0043] The consumer device may be a terminal device, a network element within the network, a network management device, or a third-party service function (such as an application function (AF)).

[0044] It is understood that, depending on the different sensing business scenarios, the network architecture of the sensing business system provided in this application may include, but is not limited to, those specific to the sensing business system. Figure 1b As shown, as compared Figure 1b The number of network elements, etc., is not limited here.

[0045] Based on the aforementioned description of the perception service system, the technical solutions provided by the embodiments of this application will be explained in detail below with reference to the accompanying drawings and through some implementation methods and application scenarios.

[0046] like Figure 2 The diagram shown illustrates a data transmission method 200 provided in an exemplary embodiment of this application. This method 200 can be executed, but is not limited to, by an access network device (such as NG-RAN), specifically by hardware and / or software installed in the access network device. In this embodiment, the method 200 may include at least the following steps.

[0047] S210, RAN receives the first sensing service control message sent by the first network element.

[0048] The first sensing service control message can be sent by the first network element to the access network device upon receiving a sensing service request message from a consumer device (such as an AF), to instruct the RAN to establish a sensing service shared channel (or public tunnel) corresponding to the first sensing service. The first sensing service can be a target detection service, a target tracking service, a target imaging service, etc.

[0049] As one possible implementation, when the consumer device sends a sensing service request message to the first network element, it may or may not go through the NEF. For example, Figure 1b As shown, when passing through the NEF, the consumer device can first send the sensing service request message to the AMF, and then the AMF forwards the sensing service request message to the first network element; or it can send the sensing service request message directly to the first network element without going through the AMF, and there is no restriction here.

[0050] Optionally, considering that the sensing service request message is used to request the first network element to perform a first sensing service, including establishing a sensing service sharing channel corresponding to the first sensing service, the sensing service request message may include description information of the first sensing service, object area of ​​the first sensing service, object user information, etc.

[0051] It is understood that the description information of the first sensing service is used to describe the first sensing service. For example, in this embodiment, the description information of the first sensing service may include at least one of the following (11)-(18).

[0052] (11) The type of the first sensing service.

[0053] The type of the first sensing service can be defined based on the sensing physical range and / or the real-time requirements of the first sensing service. For example, the type of the first sensing service may include, but is not limited to: Type I: large sensing range and high real-time requirement (Delay Critical LSS); Type II: large sensing range and low real-time requirement (LSS); Type III: small sensing range and low real-time requirement (Delay Critical SSS); Type IV: small sensing range and low real-time requirement (SSS), ...

[0054] (12) Sensing quantity, which can also be understood as the sensing measurement data required by the consumer device. For example, the sensing quantity may include, but is not limited to: 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 of the sensing object, and the material analysis of the sensing object.

[0055] (13) The purpose or application of the first sensing service, such as the first sensing service being used for target tracking, target detection, etc.

[0056] (14) The granularity of the first sensing service, such as per user equipment (per UE), per user group, or per region.

[0057] (15) Sensing Service Time. The sensing service time is used to define the time information for the execution of the first sensing service.

[0058] (16) Reporting information of sensing measurement data. The reporting information of sensing measurement data is used to define the conditions, reporting time, reporting format, and number of reporting times for sensing measurement data.

[0059] (17) The Quality of Service (QoS) requirements (or perception indicators) of the first perception service.

[0060] The service quality of the first sensing service includes, but is not limited to, at least one of the following: sensing accuracy, sensing error, maximum sensing range, sensing latency, detection probability, false alarm probability, sensing priority level, and sensing signal quality.

[0061] Optionally, the perception accuracy may include: distance resolution, imaging resolution, movement speed resolution, or angle resolution, etc.

[0062] The perception error may include: distance error, imaging error, or movement speed error, etc.

[0063] (18) Service scope information of the first sensing service.

[0064] The service range information is used to specify the scope within which the first sensing service is performed for the sensing service object. Optionally, the sensing service range can be a relative location range (e.g., within 20 meters) or an absolute location range, such as one or more Tracking Area Identity (TAI(s)), one or more cell ID(s) or one or more area IDs (e.g., Tiananmen Square in Beijing).

[0065] Furthermore, the first network element can select a sensing device serving the first sensing service, such as one or more sensing signal transmitting devices or one or more sensing signal measuring devices, based on the sensing service request message.

[0066] In addition, the first network element can also obtain target policy information for the first sensing service based on the sensing service request message. The target policy information includes sensing QoS policy information and / or communication transmission service quality policy information, so that the subsequent execution of the first sensing service (such as service measurement) can be performed in accordance with the sensing QoS requirements, thereby ensuring the sensing QoS.

[0067] In this embodiment, the perceived service quality policy information is used to characterize the resources and / or perceived execution policies allocated by the communication network (which can also be understood as the aforementioned perceived service network) to the first perceived service.

[0068] Optionally, the sensing service quality policy information may include, but is not limited to, one or more of the following: sensing priority level, sensing delay budget (SDB), sensing resolution (SR), maximum sensing range (MSR), sensing error (SE), continuous sensing capacity (CSC), sensing update rate, sensing signal quality, sensing security, sensing privacy, detection probability, and false alarm probability.

[0069] For ease of understanding, the relevant information of each parameter that may be included in the aforementioned perceived service quality strategy information can be shown in Table 1.

[0070] Table 1

[0071]

[0072]

[0073] The communication transmission QoS policy information is used to characterize the communication transmission resources and / or communication transmission policies allocated by the communication network for the first perceived service. Examples include 5G QoS parameters defined in 3GPP TS23.501 (such as the 5G QoS Identifier (5QI), Allocation and Retention Priority (ARP), etc.).

[0074] Of course, in this embodiment, as a possible implementation, the way the first network element obtains the target policy information may include the following method 1 and / or method 2.

[0075] Method 1: The first network element sends a policy request message to the Policy Control Function (PCF) to obtain the target policy information from the PCF.

[0076] Optionally, the policy request message is determined by the first network element based on the received first sensing service control message. Based on this, the policy request message may include at least one of the following (21)-(24).

[0077] (21) Description information of the first sensing service.

[0078] (22) The object area of ​​the first sensing service.

[0079] (23) Information of the target user of the first sensing service.

[0080] (24) Identification information of sensing devices, wherein the sensing devices include sensing signal transmitting devices and / or sensing signal measuring devices.

[0081] Method 2: The first network element generates the target policy information itself. The rules for generating the target policy information by the first network element can be implemented through protocol agreements, higher-level configurations, etc., and are not limited here.

[0082] In addition to acquiring the target policy information, the first network element can also establish a sensing session corresponding to the first sensing service based on the sensing service request message, and / or send a sensing resource configuration message to the sensing signal transmitting device (such as RAN or user equipment) based on the sensing service request message.

[0083] The establishment of a sensing session corresponding to the first sensing service by the first network element based on the sensing service request message can be understood as follows: the first network element allocates a corresponding first sensing session identifier ((sensing session ID, SSID)) to the first sensing service so as to facilitate subsequent acquisition, transmission, analysis of sensing measurement data, modification of the first sensing service, deletion of the first sensing service, etc. based on the first SSID.

[0084] It should be noted that the order in which the first network element acquires the target policy information and establishes the sensing session corresponding to the first sensing service is not important. That is, the first network element can acquire the target policy information first and then establish the sensing session corresponding to the first sensing service; or it can establish the sensing session corresponding to the first sensing service first and then acquire the target policy information. There is no restriction here.

[0085] The first network element sends a sensing resource configuration message to the sensing signal transmitting device (such as RAN or user equipment) according to the sensing service request message. This message is used by the sensing signal transmitting device to perform corresponding resource configuration, enabling it to transmit sensing signals according to the resource configuration corresponding to the sensing resource configuration message. For example, it may transmit sensing signals using a specific spectrum, a specific modulation method, a synchronization period, etc.

[0086] Optionally, the sensing resource configuration message may also include part or all of the description information of the first sensing service, without limitation.

[0087] Furthermore, considering that the first sensing service control message sent by the first network element to the RAN is used to establish a corresponding signaling or user plane connection (such as a sensing service shared channel) for the first sensing service, the first sensing service control message can at least include the tunnel information of the first network element to indicate the endpoint of the first network element in the tunnel between the RAN and the first network element. In other words, the tunnel information of the first network element enables the RAN to know the uplink target network element (i.e., the first network element) for subsequent sensing measurement data reporting.

[0088] The tunnel information of the first network element may include, but is not limited to, the tunnel endpoint identification information (tunnel endpoint ID of SF, TEID of SF) and / or the address information of the first network element, such as the IP address information of the first network element.

[0089] S220, the RAN establishes a shared channel for sensing services.

[0090] The sensing service sharing channel is established by the RAN after receiving the first sensing service control message sent by the first network element, and the sensing service sharing channel corresponds to the tunnel information of the first network element. The sensing service sharing channel is used to transmit at least one sensing measurement data corresponding to the first sensing service.

[0091] It can be understood that, in this embodiment, the tunnel information corresponding to the first network element corresponds one-to-one with the first sensing service initiated by the consumer device (such as AF). That is, a sensing service shared channel (which can also be understood as a public tunnel) is established for the first sensing service for the transmission of subsequent sensing measurement data, and all sensing data related to the first sensing service (regardless of how many sensing devices the sensing data comes from) is transmitted through the sensing service shared channel.

[0092] In this embodiment, for a sensing service scenario involving one or more sensing devices (such as sensing signal transmitting devices, sensing signal measuring devices, etc.) corresponding to a sensing service, a sensing service shared channel is established for a sensing service at the granularity of the sensing service. This can effectively avoid the problems of channel redundancy and resource waste caused by establishing multiple transmission channels for a sensing service in related technologies while ensuring efficient transmission of sensing measurement data.

[0093] like Figure 3 The diagram shown is a flowchart illustrating a data transmission method 300 provided in an exemplary embodiment of this application. This method 300 can be executed, but is not limited to, by an access network device (such as NG-RAN), specifically by hardware and / or software installed in the access network device. In this embodiment, the method 300 may include at least the following steps.

[0094] S310, RAN receives the first sensing service control message sent by the first network element.

[0095] The first sensing service control message includes at least the tunnel information of the first network element.

[0096] It is understood that, in addition to referring to the relevant description in method embodiment 200, as a possible implementation method, the first sensing service control message may also include at least one of the following (31)-(34).

[0097] (31) Sensing service quality policy information, used to characterize the sensing service-related resources and / or sensing execution policies allocated to the first sensing service.

[0098] Optionally, the perceived service quality policy information may include at least one of the following (3101)-(3112).

[0099] (3101) Perception delay budget.

[0100] (3102) Perceptual resolution.

[0101] (3103) Perception range.

[0102] (3104) Perception error.

[0103] (3105) Continuous perception ability.

[0104] (3106) Perception update frequency.

[0105] (3107) Perceived security.

[0106] (3108) Perceive privacy.

[0107] (3109) Detection probability.

[0108] (3110) False alarm probability.

[0109] (3111) Perception priority level.

[0110] (3112) Sensing signal quality.

[0111] It is understood that the parameters in (3101)-(3112) above can be referred to the relevant description in method embodiment 200. To avoid repetition, they will not be repeated here.

[0112] (32) Communication transmission service quality policy information, used to characterize the communication transmission resources and / or communication transmission policies allocated for the first perceived service, such as 5G QoS parameters (such as 5QI, ARP, etc.) defined in 3GPP TS 23.501.

[0113] (33) Description information of the first sensing service.

[0114] (34) The first SSID corresponding to the first sensing service, and the first SSID corresponds to the shared channel of the sensing service.

[0115] Meanwhile, the first SSID is used to identify the sensing session corresponding to the first sensing service to the RAN. The sensing session corresponds to the sensing service sharing channel, that is, the sensing service sharing channel corresponds one-to-one with the first SSID, so that the first network element and the RAN can acquire, analyze and process sensing measurement data, modify / delete the first sensing service, etc. based on the first SSID.

[0116] Additionally, it should be noted that in this embodiment, the specific information included in the first sensing service control message can be determined by protocol agreement, higher-level configuration, etc. For example, it can be agreed by protocol that the information included in the first sensing service control message is different depending on the role of the RAN in the sensing network system.

[0117] For example, when the RAN acts as the transmission node for sensing measurement data, the first sensing service control message may include part or all of the communication transmission service quality policy information to instruct the RAN to reserve corresponding access network resources (such as bandwidth resources) or to perform corresponding access network scheduling (such as air interface delay, packet loss rate, etc.) for the transmission of sensing measurement data.

[0118] For example, when the RAN simultaneously acts as a measurement device for sensing signals (such as a sensing signal measurement device) and a transmission node for sensing measurement data, the first sensing service control message may include part or all of the sensing service quality policy information to instruct the RAN to measure the sensing signals according to the sensing service quality policy information. For example, the RAN performs corresponding measurement on the measurement quantities (such as signal angle, signal strength, etc.) indicated in the sensing service quality policy information according to a certain measurement accuracy to obtain sensing measurement data.

[0119] Of course, in this scenario, the first sensing service control message may also include part or all of the description information of the first sensing service.

[0120] Furthermore, in one implementation, if the RAN acts only as a transmission node, then after receiving the first sensing service control message, the RAN can send a third sensing service control message to the sensing signal measurement device (such as a UE or other RAN) based on the first sensing service control message to establish the first sensing service. For example, the content of the third sensing service control message can be included in the first sensing service control message. After receiving the first sensing service control message, the RAN obtains the content of the third sensing service control message from it and sends it to the sensing signal measurement device as a third sensing service control message.

[0121] Based on this, the third sensing service control message may include at least one of the following (41)-(44).

[0122] (41) Some or all of the information of the perceived service quality strategy, used to characterize the perceived service-related resources and / or perceived execution strategy allocated to the first perceived service.

[0123] (42) Some or all of the descriptive information of the first sensing service.

[0124] (43) Part or all of the communication transmission quality of service strategy information applicable to the sensing signal measurement device.

[0125] (44) The first SSID corresponding to the first sensing service.

[0126] It is understood that the implementation of (41)-(44) above can refer to the above description of the first perception service control message. To avoid repetition, it will not be repeated here.

[0127] Correspondingly, after receiving the third sensing service control message, the sensing signal measurement device can also measure the sensing signal according to the third sensing service control message to obtain at least one sensing measurement data, and send the at least one sensing measurement data to the RAN through the data channel.

[0128] As one possible implementation, when the sensing signal measurement device sends at least one sensing measurement data through the data channel, it can also send the SSID corresponding to each of the at least one sensing measurement data, so that the RAN can associate the sensing measurement data.

[0129] It should be noted that the "data channel" between the sensing signal measurement device and the RAN for transmitting the at least one sensing measurement data can be established by the sensing measurement device based on a received second sensing service control message. That is, the RAN can send a second sensing service control message to the sensing signal measurement device, causing the sensing signal measurement device to establish a data channel between the RAN and the sensing signal measurement device based on the second sensing service control message, thereby enabling the sensing signal measurement device to use the data channel between the RAN and the sensing signal measurement device to transmit the at least one sensing measurement data to the RAN.

[0130] It is understood that when the sensing signal measurement device includes a sensing terminal device, the data channel between the RAN and the sensing terminal device is a radio air interface data bearer (i.e., a radio data bearer (DRB)).

[0131] Alternatively, when the sensing signal measurement device includes a sensing base station device, the data channel between the RAN and the sensing base station device is an Xn interface data bearer.

[0132] Optionally, the second sensing service control message may include at least one of the following (51)-(54).

[0133] (51) The first SSID.

[0134] (52) Some or all of the information of the perceived service quality strategy.

[0135] (53) Some or all of the descriptive information of the first sensing service.

[0136] (54) Part or all of the communication transmission quality of service strategy information applicable to the sensing signal measurement device.

[0137] It is understood that the implementation of (51)-(54) above can be referred to the above description of the first sensing service control message. To avoid repetition, it will not be repeated here.

[0138] Furthermore, the third sensing control message and the second sensing control message can be sent simultaneously through the RAN. For example, if the first sensing service control message sent by the first network element to the RAN contains the information element content from the aforementioned second and third sensing control messages, then the RAN retrieves the information elements it needs and forwards the information elements destined for the sensing signal measurement device to the sensing signal measurement device in one message (e.g., the second and third sensing control messages are combined), or forwards the information elements destined for the sensing signal measurement device to the sensing signal measurement device in two messages (e.g., the second and third sensing control messages are independent).

[0139] It should be noted that the aforementioned first sensing service control message, second sensing service control message, or third sensing service control message can all be transmitted using signaling containers to improve transmission reliability and security.

[0140] For example, the transmission of the first sensing service control message using a signaling container will be described here. Specifically, the first network element can encapsulate the first sensing service control message in a signaling container and send it to the RAN. The content of the signaling container is not visible to other network elements besides the RAN.

[0141] Optionally, the first network element may encapsulate all the information in the first sensing service control message in a signaling container, or it may split the information in the first sensing service control message and encapsulate it in multiple signaling containers. For example, the tunnel information and the communication transmission policy information of the first network element may be encapsulated in the first signaling container, and the sensing service quality policy information and the description information of the first sensing service may be encapsulated in the second signaling container. No limitation is imposed here.

[0142] S320, the RAN establishes a shared channel for sensing services.

[0143] The sensing service sharing channel corresponds to the tunnel information of the first network element, and the sensing service sharing channel is used to transmit at least one sensing measurement data corresponding to the first sensing service.

[0144] It is understood that, in addition to referring to the relevant description in method embodiment 200, as a possible implementation, the process of the RAN establishing a sensing service shared channel may include: the RAN establishing the sensing service shared channel according to the sensing service quality policy information, wherein the sensing service shared channel transmits the sensing measurement data for the first sensing service based on the communication transmission service quality policy information, thereby enabling the measurement and transmission of sensing measurement data to be performed in accordance with the sensing service quality requirements, and thus improving the overall service quality of the sensing service.

[0145] S330, the RAN sends a first sensing service response message to the first network element.

[0146] The first sensing service response message is used at least to indicate to the first network element whether the sensing service sharing channel has been successfully established. Optionally, the first sensing service response message includes at least one of the following (61)-(63).

[0147] (61) First indication information, used to indicate to the first network element whether the sensing service sharing channel corresponding to the first sensing service has been successfully established.

[0148] (62) The tunnel information of the RAN. Optionally, the tunnel information of the RAN includes the tunnel endpoint identification information of the RAN and / or the address information of the RAN, such as the IP address information of the RAN.

[0149] (63) Second indication information, used to indicate to the first network element whether the first sensing service has been accepted or successfully executed.

[0150] It should be noted that when the RAN acts as a transmission node, the second indication information comes from one or more sensing devices (such as sensing signal transmitting devices and / or sensing signal measuring devices, etc.). That is, the second indication information is used to indicate to the first network element whether the first sensing service has been accepted or successfully executed by the sensing device.

[0151] In addition, the aforementioned first instruction information and second instruction information can be explicit or implicit instructions, and there is no limitation on this.

[0152] S340, the RAN acquires at least one sensing measurement data.

[0153] Optionally, depending on the sensing signal measurement device, the RAN may acquire sensing measurement data in different ways.

[0154] For example, if the RAN can be used as a sensing signal measurement device, then the RAN can receive sensing signals sent by at least one sensing signal transmitting device, and perform corresponding measurements on the received at least one sensing signal to obtain at least one sensing measurement data corresponding to the at least one sensing signal, i.e., the at least one sensing measurement data.

[0155] For example, if the RAN acts as a transmission node but not as a sensing signal measurement device, then the RAN can receive at least one sensing measurement data sent by at least one sensing signal measurement device, wherein the at least one sensing measurement data is obtained by the at least one sensing signal measurement device measuring the sensing signal.

[0156] For example, while acting as a sensing signal measurement device, the RAN can also receive sensing measurement data sent by other sensing signal measurement devices, and then use the sensing measurement data it measures and the received sensing measurement data together as the at least one sensing measurement data.

[0157] Based on this, in one implementation, the RAN, while acquiring the sensing signal measurement data, can also acquire the SSID corresponding to each sensing measurement data; and determine whether each sensing measurement data is associated with the first SSID based on whether the SSID corresponding to each sensing measurement data matches the first SSID. For example, if they match, the RAN determines to associate the sensing signal measurement data with the first SSID; otherwise, it does not associate them.

[0158] Optionally, the RAN may acquire the SSID corresponding to each of the sensing measurement data in the following ways: Method 1 and / or Method 2.

[0159] Method 1: The RAN receives the SSID corresponding to each of the sensing measurement data sent by the at least one sensing signal measurement device.

[0160] Method 2: The RAN obtains the SSID corresponding to each sensing measurement data according to the identifier of the at least one sensing signal measurement device and / or the identifier information of the RAN tunnel (i.e., the data channel between the RAN and the sensing signal measurement device).

[0161] It is understood that, for method 2, for a specific sensing service (such as the first sensing service), when the RAN establishes a data channel with each sensing signal measurement device, it can establish a mapping relationship between the data channel and the SSID of the specific sensing service. This allows the RAN to map the corresponding SSID, i.e. the SSID corresponding to the sensing measurement data, based on the identification information of the sensing signal measurement device and the identification information of the sensing service shared channel when it receives sensing measurement data sent by the sensing signal measurement device.

[0162] S350, the RAN sends the sensing measurement data associated with the first SSID from the at least one sensing measurement data to the first network element through the sensing service sharing channel.

[0163] Optionally, when the RAN sends sensing measurement data through the sensing service sharing channel, it sends uplink data to the first network element based on the tunnel information of the first network element.

[0164] Accordingly, after receiving the sensing measurement data sent by the RAN, the first network element can obtain the analysis results of the first sensing service based on the sensing measurement data.

[0165] For example, the first network element can analyze the sensing measurement data according to a pre-configured algorithm corresponding to the first sensing service to obtain the analysis results of the first sensing service, and send the analysis results of the first sensing service to a consumer device, such as an auto-sensor (AF). The algorithm can be an AI-based intelligent algorithm, an external intelligent entity algorithm, or an AI model training algorithm from the first network element itself, etc., without limitation.

[0166] Optionally, depending on the type of the first sensing service, the analysis result of the first sensing service may be the user's respiratory health status information (whether it is abnormal, the degree of abnormality, etc.), or it may be the surrounding traffic hazard information (whether a pedestrian suddenly appears, the probability of appearance, the time of appearance, etc.).

[0167] Furthermore, corresponding to the establishment of the aforementioned sensing service sharing channel, if the first network element decides to modify (e.g., upon receiving a trigger message from a consumer device) the first sensing service, the first network element can follow the same path as the establishment of the sensing service sharing channel and request the RAN to modify it to the sensing service sharing channel established for the first sensing service.

[0168] For example, the first network element can send a sensing service modification request message to the RAN. The sensing service modification request message includes at least the first SSID and / or the tunnel information of the first network element. The sensing service modification request is at least used to modify the communication transmission service quality policy information corresponding to the first sensing service. Then, when the RAN receives the sensing service modification request message, it can modify the sensing service shared channel corresponding to the first SSID and / or the tunnel information of the first network element, so that the sensing service shared channel transmits the sensing measurement data of the first sensing service according to the modified communication transmission service quality policy information.

[0169] Furthermore, corresponding to the establishment of the aforementioned sensing service sharing channel, if the first network element decides to terminate the first sensing service (e.g., upon receiving a trigger message from a consumer device), then the first network element may follow the same path as the establishment of the sensing service sharing channel and request the RAN to release or delete the sensing service sharing channel established for the first sensing service.

[0170] For example, the first network element may send a sensing service deletion request message to the RAN, the sensing service deletion request message including at least one of the following: the first SSID, and the tunnel information of the first network element. Then, when the RAN receives the sensing service deletion request message, it may release or delete the sensing service shared channel corresponding to the first SSID and / or the tunnel information of the first network element.

[0171] In this embodiment, the sensing network system establishes a sensing service sharing channel at the service granularity (such as the first sensing service) upon request from the consumer device. Thus, regardless of whether the sensing measurement data related to the sensing service comes from the measurement of multiple sensing signals or from the measurement results output by multiple sensing measurement devices, it can be reported to the first network element through the sensing service sharing channel corresponding to the sensing service. This avoids the problem of needing to establish multiple transmission channels for the same sensing service but different sensing devices, effectively preventing resource waste.

[0172] Meanwhile, by considering the perception service quality requirements and communication transmission service quality requirements required for perception services, perception service measurements can be performed in accordance with the perception service quality policy information, while the perception service shared channel transmits perception measurement data in accordance with the communication transmission service quality policy information. This achieves joint optimization of perception service quality and communication transmission service quality, thereby improving the overall service quality of perception services.

[0173] Furthermore, based on the description of the aforementioned method embodiments 200-300, the implementation process of the data transmission method given in this application will be further illustrated below with reference to Examples 1 and 2, respectively.
