[0119] Below, in combination with the accompanying drawings, a notification method, processing method, receiving method, device and equipment provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0120] Please refer to FIG3 , which is a flowchart of a notification method provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0121] Step 301: The first network element obtains perception information;

[0122] Step 302: The first network element sends a perception notification message based on the perception information.

[0123] The perception information includes at least one of the following:

[0124] Information of the first terminal;

[0125] Descriptive information of the perceived target;

[0126] Information about the target area;

[0127] The perception notification message includes at least one of the following:

[0128] information of the first terminal;

[0129] Description information of the perception target;

[0130] information of the target area;

[0131] The first terminal is associated with the perception target, and the target area is associated with the perception target.

[0132] The first network element may be a core network element, such as a sensing function (SF), which is used to process sensing tasks, for example, calling sensing devices according to third-party sensing requirements, executing sensing processing, calculating sensing results, analyzing sensing results, and providing sensing results or analysis results. Of course, in some embodiments, the first network element may also be a third terminal or other device within the communication system.

[0133] The first network element may obtain the perception information by receiving the perception information from other devices, such as an AF, NF, or a terminal. Alternatively, the perception information may be generated by the first network element, such as when the first network element triggers the perception.

[0134] The above-mentioned perception target can also be understood as a perceived target, that is, the perception target is perceived during the perception process. In the embodiment of the present application, the above-mentioned perception target includes but is not limited to target objects such as terminals, people, vehicles, and buildings. Among them, when the above-mentioned perception target includes a terminal, the above-mentioned first terminal can be the above-mentioned perception target, or the above-mentioned first terminal can be another terminal associated with the above-mentioned perception target. The above-mentioned target area can be the area to which the above-mentioned perception target belongs, such as a cell, a physical location area, a street, etc.

[0135] The information of the first terminal may include the ID of the first terminal or other terminal information; the descriptive information of the perceived target may be information used to describe the perceived target, such as a picture, license plate, telephone number, terminal identifier, identity information, or other information that can describe the perceived target; the information of the target area may include an area identifier, an area name, information about terminals within the target area, etc. In some embodiments, the information about the target area included in the perception information may be different from the information about the target area included in the perception notification message. For example, the information about the target area included in the perception information may be an area identifier, while the information about the target area included in the perception notification message may be an area identifier or information about terminals within the target area.

[0136] The sending of the perception notification message may be sending the perception notification message to the second network element, or sending the perception notification message to the terminal. Since the perception notification message includes at least one of the information of the first terminal, the description of the perception target, and the information of the target area, the perception notification is implemented through this at least one item. In some embodiments, the perception notification message may also be referred to as perception notification information.

[0137] In the embodiment of the present application, in the above steps, by sending a perception notification message, perception notification can be achieved, thereby improving the privacy processing effect. For example, if the perception target or the device associated with the perception target has the right to be informed or to be aware of being perceived, by sending a perception notification message, the perception target or the device associated with the perception target can obtain the right to be informed or to be aware of being perceived, thereby avoiding the privacy issues of perception.

[0138] As an optional implementation, the above-mentioned perception information is carried through a perception request.

[0139] For example: the above-mentioned first network element receives a perception request sent by the AF, NF or terminal, and the perception request carries the above-mentioned perception information.

[0140] In this implementation, since the perception information is carried by the perception request, the perception notification can be implemented in a timely manner to improve the perception notification effect.

[0141] In some implementations, the sending of the perception notification message may be when the perception target is perceived, before the perception target is perceived, or after the perception target is perceived.

[0142] As an optional implementation manner, the perception information further includes: first perception description information; or,

[0143] The perception notification message further includes: second perception description information;

[0144] The second perception description information is generated based on the first perception description information, or the second perception description information is the same as the first perception description information.

[0145] The above-mentioned second perception description information is generated based on the first perception description information. The second perception description information can be obtained by deleting, adding or changing the first perception description information. The specific information can be determined according to business needs or scenario requirements.

[0146] In some embodiments, the first perception description information may include at least one of the following:

[0147] Perception service type, perception service purpose, perception service granularity, perception service accuracy, perception service time, perception data reporting information, and perception service quality of service (QoS) requirements.

[0148] In some embodiments, the second perception description information may include at least one of the following:

[0149] Perception service type, perception service purpose, perception service granularity, perception service accuracy, perception service time, perception data reporting information, and perception service quality requirements.

[0150] It should be noted that the content included in the above-mentioned second perception description information may be different from that included in the above-mentioned first perception description information. For example, the first perception description information may include perception data reporting information and perception business service quality requirements, while the second perception description information may not include perception data reporting information and perception business service quality requirements, and the remaining description information may be included, and the included content may be the same or different.

[0151] The above-mentioned perception service types are used to define perception service types, such as those based on the perception physical range and real-time requirements. For example, Type I: large perception range and high real-time requirements; Type II: large perception range and low real-time requirements; Type III: small perception range and low real-time requirements; and Type IV: small perception range and low real-time requirements.

[0152] The above-mentioned perception service purpose is used to indicate the purpose of perception, such as perception used for respiratory monitoring, or surrounding traffic environment monitoring, etc.

[0153] The aforementioned sensing service granularity indicates the granularity of the sensing service, such as the granularity of the terminal or area sensing service, and indicates that sensing measurement and reporting are performed according to the terminal granularity or the area granularity.

[0154] The above-mentioned perception service accuracy indicates the accuracy of the perception service, such as high accuracy or low accuracy. The specific accuracy level can be agreed upon by agreement.

[0155] The perception service time is used to define the time information for the perception service execution. It can be absolute time information (Monday, 13:00-19:00) or relative time information (such as within the next month). The time information can include the start time, end time, or duration.

[0156] Perception data reporting information is used to define the conditions, reporting format, and reporting frequency for perception data reporting. For example, the reporting condition may be event-triggered or periodic-triggered. In the former case, the reporting condition also includes event description information (such as determining whether the user has entered the driving state); in the latter case, the reporting condition also includes reporting cycle information (such as every 5 minutes). In addition, the reporting format is used to indicate the form in which the perception data is reported, such as indicating whether it is reported in binary / text form. The number of reports is used to indicate whether it is a one-time report or multiple reports, as well as the number of multiple reports.

[0157] In some implementations, the perceived service quality requirement may include at least one of the following:

[0158] Perception priority level, perception delay budget, perception resolution, maximum perception range, perception error, continuous perception capability, perception signal quality, perception security, perception privacy, detection probability, and false alarm probability.

[0159] Specifically, the above-mentioned perception service quality requirements can be shown in Table 1:

[0160] Table 1:

[0161] In the above table, the sensing terminal can be understood as sensing an object carrying the terminal, such as a person, a car, etc.

[0162] In the above implementation, since the perception information also includes the first perception description information, this can help the first network element to better perform perception notification, and the perception notification message also includes the second perception description information, which can improve the perception notification effect because more content can be notified.

[0163] As an optional implementation manner, the perception notification message includes information of the first terminal, and the method further includes:

[0164] The first network element obtains perception notification setting information of the first terminal;

[0165] The first network element sending a perception notification message includes:

[0166] The first network element sends a perception notification message based on the perception notification setting information.

[0167] The first network element obtains the perception notification setting information of the first terminal by querying the perception notification setting information of the first terminal from other network elements, such as querying the perception notification setting information of the first terminal from UDM.

[0168] The above-mentioned perception notification setting information may be used to indicate whether the terminal allows perception, whether it needs to send perception notification and other information, for example: the perception notification setting information is used to indicate at least one of the following:

[0169] The terminal corresponding to the perception notification setting information is allowed to be perceived or not allowed to be perceived;

[0170] The conditions under which the terminal corresponding to the perception notification setting information is allowed to be perceived;

[0171] In a case where the terminal corresponding to the perception notification setting information is perceived, notifying the terminal corresponding to the perception notification setting information;

[0173] In the case where the sensing target is sensed, notifying a terminal associated with the sensing target;

[0174] In the case where the sensing target is sensed, not notifying a terminal associated with the sensing target;

[0175] In a case where the target area is sensed, notifying terminals within the target area;

[0176] In the case that the target area is sensed, the terminals in the target area are not notified.

[0177] The above-mentioned conditions for being allowed to be perceived may include conditions such as accuracy or time for being allowed to be perceived.

[0178] When the terminal corresponding to the above-mentioned perception notification setting information is perceived, notifying the terminal corresponding to the perception notification setting information may include:

[0179] When the terminal corresponding to the perception notification setting information is perceived and meets a first preset condition, the terminal corresponding to the perception notification setting information is notified.

[0180] Among them, the above-mentioned first preset condition may be agreed upon by the protocol, or set by the terminal in the above-mentioned perception notification setting information, etc. For example: the above-mentioned first preset condition indicates that the terminal is notified at a specific perception accuracy or granularity, or the terminal is notified when it is perceived at a certain time point, or the terminal is notified when it is perceived when entering a certain area, etc.

[0181] When the sensing target is sensed, notifying the terminal associated with the sensing target may include:

[0182] When the perception target is perceived and a second preset condition is met, a terminal associated with the perception target is notified.

[0183] Among them, the above-mentioned first preset condition may be agreed upon by the protocol, or set by the terminal in the above-mentioned perception notification setting information, etc. For example: the above-mentioned second preset condition indicates that the terminal is notified at a specific perception accuracy or granularity, or the terminal is notified when it is perceived at a certain time point, or the terminal is notified when it is perceived when entering a certain area, etc.

[0184] When the target area is sensed, notifying the terminals in the target area may include:

[0185] When the target area is sensed and a third preset condition is satisfied, terminals within the target area are notified.

[0186] Among them, the above-mentioned third preset condition may be agreed upon by the protocol, or set by the terminal in the above-mentioned perception notification setting information, etc. For example: the above-mentioned third preset condition indicates that the terminal is notified at a specific perception accuracy or granularity, or the terminal is notified when it is perceived at a certain time point, or the terminal is notified when it is perceived when it enters a certain area, etc.

[0187] The first network element may send the perception notification message based on the perception notification setting information, which may be a case where the perception notification setting information allows perception or requires notification.

[0188] In the above implementation, since the perception notification message is sent to the first terminal based on the perception notification setting information, transmission resources can be saved.

[0189] In some implementations, the aforementioned awareness notification setting information may also be referred to as privacy setting information, or the awareness notification setting information may be carried in the privacy setting information.

[0190] In some implementations, sending the awareness notification message may not depend on the awareness notification setting information, that is, the first network element may directly send the awareness notification message.

[0191] As an optional implementation manner, the perception notification message includes description information of the perception target, and the method further includes:

[0192] The first network element obtains perception notification setting information of the first terminal;

[0193] The first network element sending a perception notification message includes:

[0194] The first network element sends a perception notification message to the first terminal based on the perception notification setting information.

[0196] The first network element may send the perception notification message to the first terminal based on the perception notification setting information, which may be a case where the perception notification setting information allows perception or requires notification.

[0197] In the above implementation, since the perception notification message is sent to the first terminal based on the perception notification setting information, transmission resources can be saved.

[0198] As an optional implementation manner, the perception notification message includes information about the target area, and the method further includes:

[0200] The first network element sending a perception notification message includes:

[0201] The first network element sends a perception notification message based on the information of the second terminal or the perception notification setting information.

[0202] The above-mentioned second terminal represents a terminal within the above-mentioned target area, and the above-mentioned second terminal may be a terminal with or without perception notification setting information, wherein the terminal with perception notification setting information may refer to a terminal whose perception notification setting information indicates that perception needs to be notified.

[0203] Among them, the above-mentioned perception notification setting information can be found in the corresponding description of the above-mentioned implementation method and will not be repeated here.

[0204] The above-mentioned first network element obtains the information of the second terminal in the target area by receiving the information of the second terminal in the target area sent by other network elements, such as receiving the information of the second terminal in the target area sent by UDM or AMF.

[0205] The first network element obtaining the perception notification setting information of the terminal in the target area may be receiving the perception notification setting information of the terminal in the target area sent by other network elements, such as receiving the perception notification setting information of the terminal in the target area sent by the UDM or AMF. And the perception notification setting information of the terminal in the target area may be the perception notification setting information of any terminal in the target area, or the perception notification setting information of multiple terminals in the target area.

[0206] The above-mentioned first network element sends the perception notification message based on the information of the second terminal, which may be to carry the information of the second terminal in the perception notification message, or to send the perception notification message when the second terminal indicates that the second terminal has perception notification setting information.

[0207] The first network element may send the perception notification message based on the perception notification setting information, which may be a case where the perception notification setting information allows perception or requires notification.

[0208] In the above implementation, since the first network element sends the awareness notification message based on the information of the second terminal or the awareness notification setting information, transmission resources can be saved.

[0209] As an optional implementation, sending the awareness notification message includes:

[0210] Sending the awareness notification message to a second network element, where the second network element includes at least one of the following:

[0211] AMF, the first terminal, terminals in the target area, wireless access network equipment, and a Short Message Service Center (SMSC).

[0212] Among them, all or part of the terminals in the above-mentioned target area, for example, include the second terminal described in the above-mentioned embodiment.

[0213] The above-mentioned AMF may be the AMF corresponding to the above-mentioned target area. For example, when the perception information includes information of the target area, the first network undoubtedly queries the UDM for the AMF corresponding to the target area.

[0214] When the second network element includes AMF, wireless access network equipment, and SMSC, the first network element sends a perception notification message to the first terminal or the terminal in the target area through AMF, wireless access network equipment, and SMSC.

[0215] In the case where the above-mentioned second network element includes the first terminal or terminals within the target area, perception notification messages may be sent to these terminals when these terminals have perception notification setting information. For example, the first terminal is included in the perception information, and the first network element retrieves the perception notification setting information of the first terminal from the UDM or UDR, and when there is perception notification setting information, the perception notification message is sent to the first terminal.

[0216] In this implementation, the perception notification message can be sent in a variety of ways.

[0217] In some embodiments, the awareness notification message is an awareness notification request.

[0218] Among them, the perception notification request is a request for perception notification, for example: requesting the second network element to send a perception notification to the terminal through the perception notification request, and the above-mentioned perception request is a request for requesting perception, for example: other network elements send a perception request to the first network element to request the first network element to perform a perception operation.

[0219] It should be noted that, in some implementations, the above-mentioned perception notification message may be perception notification information, and the perception notification information may be carried in the perception notification request.

[0220] In this implementation, due to the sent perception notification request, the first network element can implement perception notification through other network elements to achieve the diversity of perception notification and meet the needs of more services or scenarios. For example: the first network element receives the perception request and sends a perception notification message to the terminal or wireless access network device, and the perception notification message includes the perception target area, perception description information (perception accuracy, time, etc.), etc., wherein, sending the perception notification message to the terminal or wireless access network device includes, the first network undoubtedly sends a perception notification request to the AMF, and the perception notification request carries the perception notification information, the ID of the first terminal, the information of the target area, the perception description information and other information to the AMF, triggering the AMF to forward the perception notification information to the corresponding first terminal or wireless access network device.

[0221] Optionally, the second network element is an SMSC, and before sending the awareness notification message to the second network element, the method further includes:

[0222] Sending a first perception notification request to the AMF, where the first perception notification request includes information about the target area;

[0223] receiving a first reply message sent by the AMF, where the first reply message includes information of at least one terminal in the target area;

[0224] The sending the perception notification message to the second network element includes:

[0225] A second awareness notification request is sent to the SMSC, where the second awareness notification request includes: information of a terminal having awareness notification setting information among the at least one terminal, or information of the at least one terminal.

[0226] The first perception notification request includes the information of the target area and may include an identifier of the target area.

[0227] The above-mentioned first reply message includes information about at least one terminal in the target area, which may be a terminal detected in the above-mentioned target area after the AMF receives the above-mentioned first perception notification request.

[0228] The terminal with perception notification setting information in the above-mentioned at least one terminal may be that the first network element queries the UDM whether the above-mentioned at least one terminal has privacy notification settings to determine the terminal with perception notification setting information, such as the terminal whose perception notification setting information is the terminal that needs to be notified.

[0229] The above-mentioned second perception notification request includes the information of the at least one terminal, which can be understood as the first network element does not consider the perception notification setting information, but directly sends the perception notification request to these terminals through the SMSC.

[0230] After receiving the second awareness notification request, the SMSC sends an awareness notification message to the at least one terminal or a terminal with awareness notification setting information among the at least one terminal based on the second awareness notification request.

[0231] In this implementation, it is possible to send a short message of perception notification to the terminal through the SMSC, so that the user of the terminal can more easily know that he is being perceived through the short message, thereby improving the reliability of the perception notification, and it is possible to send a perception notification message to at least one of the above-mentioned terminals or at least one terminal with perception notification setting information, thereby saving transmission resources.

[0232] It should be noted that, in some implementations, the first network element may send a perception notification message directly to the AMF, the terminal in the target area, the wireless access network device or the SMSC.

[0233] Optionally, the second network element is a terminal in the target area, and before sending the perception notification message to the second network element, the method further includes:

[0234] Sending a third perception notification request to the AMF, where the third perception request includes information about the target area;

[0235] receiving a second reply message sent by the AMF, where the second reply message includes information of at least one terminal in the target area;

[0236] The sending the perception notification message to the second network element includes:

[0237] Sending a perception notification message to the at least one terminal.

[0238] The second perception notification request includes the information of the target area and may include an identifier of the target area.

[0239] The above-mentioned second reply message includes information about at least one terminal in the target area, which may be the terminal detected in the above-mentioned target area after the AMF receives the above-mentioned third perception notification request.

[0240] The awareness notification message sent to the at least one terminal may include information of these terminals, such as an identifier of the terminal or an identifier of a terminal group.

[0241] In this implementation, it is possible to send a perception notification message to the at least one terminal, thereby saving transmission resources.

[0242] As an optional implementation, the method further includes:

[0243] The first network element receives a notification reply message sent by the first terminal or a terminal in the target area.

[0244] The notification reply message is used to indicate the terminal's response to the perception notification information, such as whether to allow perception or not. In some embodiments, the notification reply message may be used to indicate at least one of the following:

[0245] The terminal sending the notification reply message allows being perceived or does not allow being perceived;

[0246] The terminal sending the notification reply message is allowed to be perceived.

[0247] The above-mentioned conditions for being allowed to be perceived may include conditions such as accuracy or time for being allowed to be perceived.

[0248] In this implementation, since a notification reply message is received, this can support the terminal and the network side to perform perception negotiation, so as to improve the privacy processing effect of the terminal.

[0249] Optionally, the method further includes at least one of the following:

[0250] When the notification reply message indicates that the terminal sending the notification reply message does not allow perception, blurring the perception data or rejecting the perception request corresponding to the perception information, the perception data being data obtained by performing a perception operation;

[0251] If the notification reply message indicates that the terminal sending the notification reply message allows being sensed, selecting a sensing device or performing a sensing operation;

[0252] When the notification reply message indicates the conditions under which the terminal sending the notification reply message is allowed to be perceived, a perception device is selected according to the conditions under which perception is allowed, or data processing corresponding to the conditions under which perception is allowed is performed on the perception data, and the perception data is data obtained by performing a perception operation.

[0253] The above-mentioned fuzzy processing of the perception data may be to fuzzify the perception data to achieve the protection of the privacy of the terminal, for example: the fuzzy processing of the perception data includes: reducing the accuracy of the perception data. It should be noted that the embodiment of the present application does not limit the fuzzy processing to reducing the accuracy of the perception data. For example: in some embodiments, the fuzzy processing of the perception data may also be to delete the perception data. For example, if multiple data of the perception target are perceived, some data are deleted, and the perception data that does not involve privacy or involves relatively weak privacy is retained. By performing the above-mentioned fuzzy processing on the perception data, the privacy protection effect can be improved.

[0254] In addition, in the case of rejecting the perception request corresponding to the perception information, the first network element may also provide feedback to the AF, NF or terminal, indicating that the terminal that sent the notification reply message cannot be perceived.

[0255] The selecting of the sensing device may be selecting a device that performs the sensing operation, such as selecting a radio access network device or a core network element that performs the sensing operation. The selecting of the sensing device according to the condition for allowing sensing may be selecting a sensing device that matches the condition.

[0256] The above-mentioned data processing performed on the perception data corresponding to the conditions for allowing perception may be to process the accuracy of the perception data so that the accuracy matches the accuracy of the above-mentioned conditions for allowing perception, or may be to filter the perception data so that the time of the perception data matches the time of the above-mentioned conditions for allowing perception.

[0257] In the above implementation, corresponding processing can be flexibly performed based on the notification reply message, so that the perception data finally processed matches the terminal, thereby improving the perception effect.

[0258] In an embodiment of the present application, a first network element obtains perception information; the first network element sends a perception notification message based on the perception information; wherein the perception information includes at least one of the following: information about a first terminal; description information of a perception target; and information about a target area; wherein the perception notification message includes at least one of the following: information about the first terminal; description information of the perception target; and information about the target area; wherein the first terminal is associated with the perception target, and the target area is associated with the perception target.

For its specific implementation, please refer to the relevant description of the embodiment shown in FIG3 . To avoid repeated description, this embodiment will not be described in detail.

[0348] The following describes the method provided in the embodiments of the present application through multiple examples:

[0349] Example 1:

[0350] This embodiment mainly describes how a terminal sets awareness notification setting information in the UDM / UDR, as shown in FIG7 , including the following steps:

[0351] Step 1. The terminal sends a terminal-aware privacy setting request via a Non-Access Stratum (NAS) message. This request carries awareness notification setting information, which indicates when the terminal is aware of privacy. Optionally, the message also carries the awareness granularity (coarse or fine), indicating at which granularity the terminal is notified. For example, if the granularity is fine, the terminal is notified, but if the granularity is coarse, the terminal is not notified.

[0352] Step 2.AMF calls the UDM parameter provision update (sensing privacy) service operation (Nudm_ParameterProvision_Update(Sensing privacy)service operation), which carries the perception notification setting information in step 1. UDM further stores or updates the perception privacy setting of the terminal. If the perception privacy setting of the target terminal is set, the perception privacy setting of the target terminal is further stored or updated in the UDR.

[0353] Step 3.AMF returns the terminal-aware privacy settings to the terminal

[0354] Example 2:

[0355] In this embodiment, the target terminal (i.e., the first terminal in the above embodiment) is carried in the sensing request, that is, the target terminal is sensed and notified, as shown in FIG8 , including the following steps:

[0356] Step 1. The SF receives a sensing request from the AF / NF / terminal, which carries the target terminal ID and the sensing service description. The sensing service description information includes at least one of the following information:

[0357] Perception service type, which can be defined based on the perception physical range and real-time requirements. For example, Type I: large perception range and high real-time requirements; Type II: large perception range and low real-time requirements; Type III: small perception range and low real-time requirements; Type IV: small perception range and low real-time requirements;

[0358] Perception business purpose, such as perception for respiratory monitoring, or surrounding traffic environment monitoring, etc.

[0359] The granularity of the sensing service (e.g., per terminal or per area) indicates that sensing measurements are performed and reported according to the terminal granularity or area granularity.

[0360] The accuracy of the perception service: high precision, low precision.

[0361] Perception service time defines the time information for the perception service execution. This can be absolute time information (Monday, 13:00-19:00) or relative time information (such as within the next month). This time information can include the start time, end time, or duration.

[0362] Perception data reporting information. It is used to define the conditions, reporting format, and reporting frequency for perception data reporting. For example, the reporting condition may be event-triggered or periodic-triggered. In the former case, the reporting condition also includes event description information (such as determining whether the user has entered the driving state); in the latter case, the reporting condition also includes reporting cycle information (such as every 5 minutes). In addition, the reporting format is used to indicate the form in which the perception data is reported, such as indicating whether it is reported in binary / text form. The number of reports is used to indicate whether it is a one-time report or multiple reports, as well as the number of multiple reports.

[0363] Perceived service quality of service (QoS) requirements, where perceived QoS includes quality parameters of one or more dimensions listed in Table 1 above

[0364] Step 2. SF calls a get operation (Nudm_SDM_Get operation) to call the perception privacy setting of the target terminal and obtain the perception notification setting of the target terminal, that is, the perception communication setting information is set to perception notification, that is, perception needs notification.

[0365] Step 3. In step 2, if the target terminal has a perception notification setting, the SF calls the perception service operation of the AMF and sends a perception notification request to the AMF and the ID of the target terminal. The perception notification request carries a perception description including the perception accuracy.

[0366] Step 4. After the AMF receives the above-mentioned perception notification request and the target terminal ID, if the target terminal is in the idle state, it executes the network-triggered service request process to make the target terminal enter the connected state.

[0367] Step 5.AMF forwards the perception notification request to the corresponding terminal via NAS message.

[0368] Step 6. After receiving the Awareness Notification Request, the target terminal optionally returns an Awareness Notification Response to the AMF via a NAS message. The Response message carries information about acceptance or rejection of the Awareness Notification. In the case of acceptance, it may also include information about the granularity of the Awareness Notification and time information.

[0369] Step 7.AMF forwards the perception notification reply to SF.

[0370] Step 8. SF performs corresponding operations based on the results, where:

[0371] In the case of acceptance, the sensing device is called to perform sensing on the target terminal;

[0372] In case of rejection, SF sends a rejection message to AF / NF / terminal;

[0373] After accepting and carrying the accepted granularity information, the SF calls the perception device to perform perception on the target terminal according to the accepted perception granularity, or after perception, adjusts the accuracy of the perception result according to the accepted perception granularity.

[0374] Step 9. SF feeds back the sensing result to AF / NF / terminal.

[0375] Example 3:

[0376] In this embodiment, the target area carried in the sensing request is sensed and the sensing terminals in the target area are notified, as shown in FIG9 , including the following steps:

[0377] Step 1. SF receives the sensing request from AF / NF / terminal, which carries the target area and sensing description (including sensing accuracy).

[0378] Step 2. SF calls the acquisition operation (Nudm_SDM_Get / Nudm_TerminalCM_Get operation) to obtain the AMF in the target area and obtain the terminal identification (Subscription Permanent Identifier, SUPI) with privacy settings. The operation carries the target area, and the UDM carries the AMF ID in the reply. The UDM carries the terminal identification (SUPI) with privacy settings in the reply. The terminal identification (SUPI) with privacy settings can be understood as the identification of the terminal that needs to be notified according to the perceived communication setting information.

[0379] Step 3. SF calls the Namf_EventExposure service operation and calls the event "Number of UEs served by the AMF and located in "Area Of Interest" served by the AMF. The event filter is set to any terminal or the terminal identifier (SUPI) in step 2. The area of ​​interest is set to the target area. The operation also carries a perception notification request to instruct the AMF to send the request to the detected terminal.

[0380] Step 4.AMF filters the event according to the event filter (event filter) of the event for any terminal, or the terminal identifier (SUPI) in step 2, and the area of ​​interest (Area Of Interest) is the target area. The event of the number of UEs served by the AMF and located in the "Area Of Interest" is executed, and for the detected terminal, the AMF sends a SF perception notification request to the detected terminal. The perception request carries a perception description, such as perception granularity, perception time, etc.

[0381] Step 5. After receiving the Awareness Notification Request, the target terminal optionally returns an Awareness Notification Response to the AMF via a NAS message. The Response message carries information about acceptance or rejection of the Awareness Notification. In the case of acceptance, it may also include information about the granularity of the Awareness Notification and time information.

[0382] Step 6.AMF forwards the perception notification reply to SF.

[0383] Step 7. SF performs corresponding operations based on the results, where:

[0384] In the case of acceptance, the sensing device is called to perform sensing on the target terminal;

[0385] In case of rejection, SF sends a rejection message to AF / NF / terminal;

[0386] After accepting and carrying the accepted granularity information, the SF calls the perception device to perform perception on the target terminal according to the accepted perception granularity, or after perception, adjusts the accuracy of the perception result according to the accepted perception granularity.

[0387] Step 8. SF feeds back the sensing result to AF / NF / terminal.

[0388] Example 4:

[0389] This embodiment mainly describes how the NG-RAN broadcasts the perception notification information in the SIB, as shown in FIG10 , including the following steps:

[0390] Step 1. SF receives the sensing request from AF / NF / terminal, which carries the target area and sensing description (including sensing accuracy).

[0391] Step 2. SF sends a communication N1N2 message (Namf_communication_N1N2 message) to AMF, which carries a perception notification request. The request carries perception description information, such as perception area, perception accuracy, etc.

[0392] Step 3. The AMF sends the perception notification request in step 2 to the NG-RAN via the N2 message.

[0393] Step 4. NG-RAN responds with an N2 message.

[0394] Step 5. NG-RAN sets the SIB message for perception notification. The SIB message for perception notification may also carry the perception notification information carried in the perception notification request, such as the perception area, perception accuracy, etc.

[0395] Step 6.AMF returns the communication N2 message (Namf_communication_N2 message) to SF.

[0396] Step 7. SF performs sensing operations.

[0397] Step 8SF returns the perception result.

[0398] Embodiment 5:

[0399] In this embodiment, the SF can directly send a perception notification message to the terminal through the perception protocol information, as shown in FIG11 , including the following steps:

[0400] Step 1. The SF receives a sensing request from the AF / NF / terminal, which carries the target terminal ID and sensing service description. The sensing service description information is as described in the above embodiment and will not be described here in detail.

[0401] Step 2. SF calls a get operation (Nudm_SDM_Get operation) to call the perception privacy setting of the target terminal and obtain the perception notification setting of the target terminal, that is, the perception communication setting information is set to perception notification, that is, perception needs notification.

[0402] Step 3. In step 2, if the target terminal has a perception notification setting, the SF directly sends the perception notification to the perceived terminal. This step can be transparently transmitted through the AMF.

[0403] Step 4. After receiving the above-mentioned perception notification request, the target terminal optionally returns a perception notification reply to the SF, wherein the reply message carries information of accepting or rejecting perception. In the case of acceptance, it may also contain information of the perceived granularity and time information.

[0404] Step 5. SF performs corresponding operations based on the results, where:

[0405] In the case of acceptance, the sensing device is called to perform sensing on the target terminal;

[0406] In case of rejection, SF sends a rejection message to AF / NF / terminal;

[0407] After accepting and carrying the accepted granularity information, the SF calls the perception device to perform perception on the target terminal according to the accepted perception granularity, or after perception, adjusts the accuracy of the perception result according to the accepted perception granularity.

[0408] Step 6. SF feeds back the sensing result to AF / NF / terminal.

[0409] Example 6:

[0410] In this embodiment, the SF can directly send a perception notification message to the terminal through the perception protocol information, as shown in FIG12 , including the following steps:

[0411] Step 1. SF receives the sensing request from AF / NF / terminal, which carries the target area and sensing description (including sensing accuracy).

[0412] Step 2. SF calls the acquisition operation (Nudm_SDM_Get / Nudm_TerminalCM_Get operation) to obtain the AMF in the target area and obtain the terminal identification (SUPI) with privacy settings. The operation carries the target area, and the UDM carries the AMF ID in the reply. The UDM carries the terminal identification (SUPI) with privacy settings in the reply. The terminal identification (SUPI) with privacy settings can be understood as the identification of the terminal that needs to be notified according to the perceived communication setting information.

[0413] Step 3. SF calls the Namf_EventExposure service operation and calls the event "Number of UEs served by the AMF and located in "Area Of Interest" served by the AMF. The event filter is set to any terminal or the terminal identifier (SUPI) in step 2. The area of ​​interest is set to the target area. The operation also carries a perception notification request to instruct the AMF to send the request to the detected terminal.

[0414] Step 4.AMF performs the event "Number of UEs served by the AMF and located in "Area of ​​Interest"" based on the event filter of the event for any terminal or the terminal identifier (SUPI) in step 2 and the target area, and for the detected terminal, AMF returns the detected perceived terminal.

[0415] Step 5.AMF returns these sensed terminals to SF, and SF directly sends a sense notification message to the sensed terminals.

[0416] Step 6. After receiving the above-mentioned perception notification request, the target terminal optionally returns a perception notification reply to the SF, wherein the reply message carries information of accepting or rejecting perception. In the case of acceptance, it may also contain information of the granularity of perception, time information, etc.

[0417] Step 7. SF performs corresponding operations based on the results, where:

[0418] In the case of acceptance, the sensing device is called to perform sensing on the target terminal;

[0419] In case of rejection, SF sends a rejection message to AF / NF / terminal;

[0420] After accepting and carrying the accepted granularity information, the SF calls the perception device to perform perception on the target terminal according to the accepted perception granularity, or after perception, adjusts the accuracy of the perception result according to the accepted perception granularity.

[0421] Step 8. SF feeds back the sensing result to AF / NF / terminal.

[0422] Embodiment seven:

[0423] In this embodiment, the SF sends a perception notification to the terminal via a short message, as shown in FIG13 , including the following steps:

[0424] Step 1. SF receives a sensing request from AF / NF / terminal. The sensing request carries the target area and sensing description (including sensing accuracy). The sensing description is the same as shown in Table 1 above and is not repeated here.

[0425] Step 2. SF calls the acquisition operation (Nudm_SDM_Get / Nudm_TerminalCM_Get operation), obtains the AMF in the target area, and obtains the terminal identification (SUPI) with privacy settings. The operation carries the target area, and the UDM carries the AMF ID in the reply. The UDM carries the terminal identification (SUPI) with privacy settings in the reply. The terminal identification (SUPI) with privacy settings can be understood as the identification of the terminal that needs to be notified according to the perceived communication setting information.

[0426] Step 3. SF calls the Namf_EventExposure service operation and calls the event "Number of UEs served by the AMF and located in "Area Of Interest" served by the AMF. The event filter is set to any terminal or the terminal identifier (SUPI) in step 2. The area of ​​interest is set to the target area. The operation also carries a perception notification request to instruct the AMF to send the request to the detected terminal.

[0427] Step 4.AMF selects the event filter of the event as any terminal, or the terminal identifier (SUPI) in step 2, and the area of ​​interest as the target area, and executes the event of the number of UEs served by the AMF and located in the "Area of ​​Interest". For the detected terminal, AMF returns a reply to SF, and the reply carries the ID information of the detected terminal to SF.

[0428] Step 5. Optionally, SF queries UDM whether the detected terminal has privacy notification settings, and UDM returns the ID of the terminal with privacy notification settings after query.

[0429] Step 6. SF sends a perception notification request to SMSC, requesting SMSC to send a short message to notify the terminal that it is perceived. The request carries the terminal ID detected above. If step 5 is executed, SF carries the terminal ID with privacy notification and may also carry perception notification description information.

[0430] Step 7. The SMSC sends a short message to the corresponding terminal according to the above request, notifying the terminal that the perception has been executed. The content of the short message includes the above perception description message.

[0431] Embodiment 8:

[0432] In this embodiment, after receiving the awareness request, the SF directly requests the SMSC to send an awareness notification short message. The SMSC sends the awareness notification short message to the terminal in the target area, as shown in FIG14 , including the following steps:

[0433] Step 1. The SF receives a sensing request from the AF / NF / terminal. The sensing request carries the target area and sensing description (including sensing accuracy). The sensing description is as shown in Table 1 above.

[0434] Step 2: SF sends an awareness notification request to SMSC, where the request carries awareness description and target area.

[0435] Step 3. After receiving the above request, the SMSC determines the target terminal in the target area according to the target area, and sends a short message to the target terminal. The short message carries the perception description information for notifying the terminal of the perception.

[0436] It should be noted that, in the above draft example, sensing the target terminal includes sensing an object carrying the target terminal, such as a person, a car, etc.

[0437] In the embodiment of the present application, the following can be achieved:

[0438] For SF:

[0439] Receive a perception request and send a perception notification message (also called perception notification information) to the terminal or NG-RAN. The perception notification message includes the perception target area, perception description (perception accuracy, time, etc.), etc.

[0440] Among them, sending the perception notification message to the terminal or NG-RAN includes, the SF sending a perception notification request to the AMF, the request carrying the perception notification message, such as the target terminal ID, target area information or perception description and other information to the AMF, triggering the AMF to forward the perception notification message to the corresponding terminal or NG-RAN.

[0441] When the target terminal is included in the perception request (i.e., the target terminal needs to be perceived), the SF retrieves the perception notification settings of the target terminal from the UDM / UDR, and when there is a perception notification setting, it sends a perception communication message to the terminal.

[0442] When the target area is included in the sensing request (i.e., sensing information in the target area is sensed), the SF queries the UDM for the target area AMF.

[0443] The receiving (target) terminal responds to the perception communication message, where the response includes an indication of acceptance or rejection of perception. In the case of acceptance, it may also carry the perceived granularity. The SF performs the perception operation based on the acceptance indication. In the case of rejection, the AF is fed back, and the target terminal cannot be perceived, or the perception data of the terminal in the target area is blurred.

[0444] For AMF:

[0445] Receive the SF's perception notification request, which includes a perception notification message, such as target terminal ID, target area information, perception description, and other information.

[0447] The AMF forwards the perception communication message to the NG-RAN, where the perception communication message includes target area information and perception description.

[0448] The AMF forwards the terminal's perception communication message and replies to the SF.

[0449] The AMF determines the NG-RAN based on the target area information.

[0450] The AMF forwards the terminal's perception notification indication information to the UDM / UDR.

[0451] For NG-RAN:

[0452] Receive the perception communication message of the SF, and set the perception notification SIB according to the perception communication message. The perception notification SIB feature also includes target area information and perception description.

[0453] For Terminal:

[0454] Send an awareness notification setting request message to the AMF. The request message contains awareness notification setting indication information, including:

[0455] Allow to be perceived; or

[0456] Not allowed to be perceived; or,

[0457] Allows for granularity of being sensed and perceived.

[0458] Receive the awareness communication message, respond to the awareness communication message, and send an awareness notification reply to the SF. The reply includes:

[0459] Allow to be perceived or,

[0460] Not allowed to be perceived or,
