[0093] It should also be understood that the above naming is only defined to facilitate the distinction between different functions and should not constitute any limitation to this application. This application does not exclude the possibility of adopting other naming in 5G networks and other networks in the future. For example, in a 6G network, some or all of the above networks may continue to use the terminology in 5G, or other names may be used. The interface name between the various network elements in Figure 1 is only an example. The name of the interface in the specific implementation may be other names, and this application does not make specific limitations on this. In addition, the name of the message (or signaling) transmitted between the above-mentioned network elements is only an example and does not constitute any limitation on the function of the message itself.

[0094] It should be noted that the aforementioned "network element" may also be referred to as an entity, device, apparatus, or module, and this application does not specifically limit this. Furthermore, in this application, for ease of understanding and explanation, the term "network element" is omitted in some descriptions. For example, the PCF network element is referred to as PCF. In this case, the "PCF" should be understood as a PCF network element or PCF entity. The following descriptions of identical or similar situations are omitted.

[0095] The NWDAF network element can receive subscription requests from consumers (such as NF, UE or OAM), collect corresponding data from the network, process and analyze the data, obtain statistical or predictive analysis results, and finally feed back the analysis results to the user.

[0096] Exemplarily, the user of the NWDAF analysis subscription (Nnwdaf_AnalyticsSubscription_Subscribe) service operation, or the analysis request (Nnwdaf_AnalyticsInfo_Request) service operation can be a 5G core network (5G core network, 5GC) NF (such as PCF, network slice selection function (network slice selection function, NSSF), AMF, SMF, NEF, NWDAF, data collection coordination function (data collection coordination function, DCCF), AF, UE or OAM. After obtaining the analysis result, NWDAF will feed it back to the user who issued the subscription or to the network element specified by the user (5GC NFs or OAM). NWDAF supports providing multiple different types of data analysis results, which are distinguished by analysis identifiers (analytics ID). For example, the analysis identifier is service experience, which indicates the service experience data analysis result; the analysis identifier is network performance, which indicates the network performance analysis result; the analysis identifier is UE mobility (UE The UE mobility analysis result is represented by the UE mobility information. When a user subscribes to or requests analysis results from the NWDAF, the user can include one or more analysis identifiers to identify the type of analysis results the user wants to obtain from the NWDAF. The NWDAF can collect the corresponding data from the network based on the analysis identifiers and feed back the derived analysis results to the user.

[0097] FIG2 is a schematic flow chart of a method 200 for providing analysis results. The method 200 is described below with reference to FIG2 .

[0098] S210: The user sends an analysis subscription / request message to the NWDAF.

[0099] For example, a user can send an analysis subscription message to NWDAF through an analysis subscription service operation, where the analysis subscription message is used to subscribe to analysis results. For another example, a user can send an analysis request message to NWDAF through an analysis request service operation, where the analysis request message is used to request analysis results.

[0100] Exemplarily, the analysis subscription message or the analysis request message may include at least one of the following parameters.

[0101] (1) A list of analytics ID(s), which may include at least one analytics ID, each of which is used to identify a subscribed or requested analytics result.

[0102] (2) Analytics filter information, which can indicate the applicable conditions of the analysis results, such as the area of ​​interest (AOI) and single network slice selection assistance information (S-NSSAI).

[0103] (3) Target of analytics reporting, which can indicate the target to which the analytics request applies. For example, the target can be a specific UE, a group of UEs, or any UE.

[0104] (4) Analytics target period: This indicates the time period for which the analysis results are applicable. In other words, the analysis target period indicates the time period for which the user wants to obtain analysis results.

[0105] S220, NWDAF sends an analysis notification / response message to the user.

[0106] After executing S210 and before executing S220 , the NWDAF may collect data and determine analysis results according to the user's subscription / request.

[0107] As an example, if the user sends an analysis subscription message in S210, NWDAF can send an analysis notification message to the user through the analysis subscription notification (Nnwdaf_AnalyticsSubscription_Notify) service operation, and the analysis notification message can indicate the analysis result. As another example, if the user sends an analysis request message in S210, NWDAF can send an analysis response message to the user through the analysis response (Nnwdaf_AnalyticsInfo_Request Response) service operation, and the analysis response message can indicate the analysis result.

[0108] Exemplarily, the analysis notification message or the analysis response message may include at least one of the following parameters.

[0109] (1) For each analytics ID, the analytics information in the requested analytics target period.

[0110] (2) Timestamp of analytics generation.

[0111] (3) Validity period: It can indicate the validity period of the analysis results.

[0112] (4) Confidence, which can indicate the confidence in the predicted analysis results.

[0113] NWDAF may provide recommended information. For example, NWDAF may provide a recommended back-off timer to AMF. For another example, NWDAF may provide recommended QoS parameters to PCF. Exemplarily, the recommended information includes but is not limited to at least one of the following:

[0114] (1) Recommended QoS parameters, such as packet delay budget (PDB), uplink-maximum bitrate, etc. The recommended QoS parameters can be one QoS parameter or a combination of multiple QoS parameters.

[0115] (2) Recommended network elements, such as UPF, application server (AS), etc.

[0116] (3) Recommended time information, such as avoidance timer, etc.

[0117] (4) Recommended UE, such as the attacked UE.

[0118] (5) Recommended location information, such as paging restriction areas, etc.

[0119] (6) Recommended load ratio, such as load balancing ratio, etc.

[0120] FIG3 is a schematic flow chart of a method 300 for providing recommendation information. The method 300 is described below with reference to FIG3 .

[0121] S310: The user sends a recommendation subscription / request message to the NWDAF.

[0122] For example, a user can send a recommendation subscription message to NWDAF through the recommendation subscription (Nnwdaf_Recommendations_Subscribe) service operation, which is used to subscribe to recommendation information. For another example, a user can send a recommendation request message to NWDAF through the recommendation request (Nnwdaf_Recommendations_Request) service operation, which is used to request recommendation information.

[0123] Exemplarily, the recommendation subscription message or the recommendation request message may include at least one of the following parameters.

[0124] (1) The desired recommendation on a given domain.

[0125] (2) The observation period [start..end] in the future on which recommendations are requested may indicate the time period for providing recommendation information, i.e., the user requests NWDAF to provide recommendation information applicable to a specific time period.

[0126] (3) The maximum tolerable delay for the provision of the recommendations.

[0127] (4) Target of event reporting: This field can indicate the target of the recommended information. For example, the target can be a UE, a group of UEs, or any UE. For example, if a user wants to obtain recommended QoS parameters and specifies the target of the event report as Subscription Permanent Identifier (SUPI) 1, it means that the user wants to obtain the recommended QoS parameters for SUPI 1.

[0128] (5) Event filtering information, which can indicate the filtering information for recommended information. For example, event filtering information can be AOI, S-NSSAI, etc. Event filtering information can also indicate the applicable conditions for recommended information. For example, if the event filtering information is cell 1, it means that the user wants to obtain recommended information within cell 1.

[0129] The desired recommendation result for a given domain may include at least one of the following parameters.

[0130] (a) The recommendation registered ID in the given domain, hereinafter also referred to as the "recommendation ID". The recommendation ID may indicate the type of recommendation information the user desires to obtain. For example, the recommendation ID may be used to identify recommended QoS parameters or recommended UPF network elements.

[0131] (b) Optimization goals: For example, when a user wants to obtain recommended QoS parameters, the optimization goal can be the mean opinion score (MOS) of the service experience, such as MOS>4.

[0132] (c) Constraints per requested parameter, which can be expressed as parameter ranges. For example, if a user wants to obtain recommended QoS parameters, the parameter range can be 50 megabits per second (Mbps) < bitrate < 100Mbps, or 20 milliseconds (ms) < delay < 50ms, etc.

[0133] The above (b) and (c) are optional.

[0134] S320, NWDAF sends a recommendation notification / response message to the user.

[0135] After executing S310 and before executing S320 , the NWDAF may collect data and determine recommendation information according to the user's subscription / request.

[0136] As an example, if the user sends a recommendation subscription message in S310, the NWDAF may send a recommendation notification message to the user through the recommendation notification (Nnwdaf_Recommendations_Notify) service operation, and the recommendation notification message may indicate the recommendation information. As another example, if the user sends a recommendation request message in S310, the NWDAF may send a recommendation response message to the user through the recommendation response (Nnwdaf_Recommendations_Response) service operation, and the recommendation response message may indicate the recommendation information.

[0137] For example, the recommendation notification message or the recommendation response message may include one or more candidate recommendation information (Recommendation). The recommendation information may include at least one of the following parameters.

[0138] (1) A reference to the recommendation registered ID in the recommendation domain may indicate the recommendation ID.

[0139] (2) The vector of tagged parameter recommended values ​​or value ranges.

[0140] (3) The associated impacts (a set of predicted analytics) if such parameters are chosen.

[0141] (4) The priority order of recommended information (a preference order in order to suggest a preference).

[0142] The above (3) and (4) are optional.

[0143] However, how to monitor the accuracy of recommended information is an urgent problem to be solved.

[0144] FIG4 is a schematic flow chart of an information processing method 400 provided in an embodiment of the present application. The method 400 can monitor the accuracy of recommendation information. The method 400 is described below with reference to FIG4 .

[0145] S410: The second network element receives an optimization target from the first network element. Correspondingly, the first network element sends the optimization target to the second network element.

[0146] The optimization objective can be used to generate recommendation information.

[0147] The second network element may be a network data analysis function network element, such as NWDAF. However, the present application does not limit the specific name of the second network element.

[0148] The first network element may be referred to as a user, a requester, or the like. However, this application does not limit the specific name of the first network element. The first network element may be a NF, a network management system, a terminal device, an access network device (e.g., a RAN), or an application function network element. The NF may be a core network element, for example, a PCF, an AMF, or an SMF.

[0149] S420: The second network element sends the recommendation information to the first network element. Correspondingly, the first network element receives the recommendation information from the second network element.

[0150] The optimization target can be used to generate recommendation information. In some optional embodiments, the second network element can generate recommendation information based on the optimization target. For example, the optimization target is a service experience MOS greater than 4. The second network element can generate recommended QoS parameters based on the optimization target, and the QoS parameters are used to meet the optimization target.

[0151] It should be noted that, in addition to being used to generate recommendation information, the optimization target can also have other functions or effects. For example, the optimization target can be used to generate accuracy information of the recommendation information, which can be described in detail below.

[0152] It should be noted that the recommendation information generated by the second network element is based on the data collected by the second network element. In other words, the recommendation information can theoretically meet the optimization objective. The second network element predicts that after the first network element uses the recommendation information, the relevant parameters can theoretically meet the optimization objective. "Meeting the optimization objective" can be understood as the recommendation information being able to achieve the optimization objective. For example, the optimization objective is to achieve a service experience MOS greater than 4. Meeting this optimization objective can mean that the second network element predicts that after the first network element uses the recommended QoS parameters, the service experience MOS greater than 4.

[0153] This application does not limit the name of the optimization target. For example, the optimization target can also be called a business target, an optimization condition, or have other names.

[0154] This application does not limit the name of the recommendation information. For example, the recommendation information can also be called a recommendation result or have other names.

[0155] The optimization goal can be carried in an analysis subscription message or an analysis request message, or in a recommendation subscription message or a recommendation request message, or in other messages. This application is not limited to this. Exemplarily, a recommendation subscription message or a recommendation request message can include a recommendation requirement object, which can include the optimization goal.

[0156] In some optional embodiments, the generated recommendation information does not meet the optimization objective. "Not meeting the optimization objective" can be understood as the recommendation information failing to achieve the optimization objective. For example, the optimization objective is for the service experience MOS to be greater than 4. This failure can occur when the second network element predicts that the service experience MOS of the first network element, after using the recommended QoS parameters, is theoretically no greater than 4, for example, a theoretical service experience MOS of 3.5.

[0157] It should be noted that S420 can be executed after S410 or before S410. It is understandable that if S420 is executed before S410, the second network element can obtain the optimization target in other processes.

[0158] S430: The second network element receives the first data.

[0159] The first data may be data corresponding to the optimization target after the first network element uses the recommendation information. In other words, the first data may be data corresponding to the optimization target after the recommendation information is applied.

[0160] The first network element uses the recommended information, which may be the first network element applying the recommended information to the corresponding network element. For example, if the recommended information is a QoS parameter, the first network element uses the QoS parameter, which may be the first network element binding the QoS parameter to a specific QoS flow.

[0161] The first data is the data corresponding to the optimization target. The term "corresponding" may mean that the type of the first data is the same as the optimization target. For example, the first data and the optimization target are both MOS of the service experience. The term "corresponding" may also mean that the first data is the corresponding actual parameter of the optimization target. The optimization target is the parameter that is expected to be achieved, but it is not necessarily achieved in practice. For example, if the optimization target is that the MOS of the service experience is greater than 4, it does not mean that the MOS of the actual service experience is greater than 4. The first data is a real, actual parameter. For example, the first data is that the MOS of the service experience is greater than 4, which indicates that the MOS of the actual service experience of the network element is greater than 4.

[0162] This application does not limit the name of the first data. For example, the first data can also be called truth data, ground truth data, ground truth data of optimization goals, true value, true value of optimization goal, or other names.

[0163] The second network element receiving the first data can also be understood as the second network element obtaining the first data, or the second network element collecting the first data, or the second network element requesting the first data.

[0164] The second network element may execute S430 in response to receiving the optimization target. That is, upon receiving the optimization target, the second network element may receive, obtain, collect, or request the first data. However, this application is not limited to this. The second network element may execute S430 based on other preconditions, or the second network element may proactively execute S430.

[0165] This application does not limit the message carried by the first data. For example, the first data can be carried in a data notification message of an application function network element or a network function. For another example, the first data can be carried in recommendation feedback information of the first network element.

[0166] S440: The second network element sends accuracy information of the recommendation information to the first network element.

[0167] The accuracy information may be determined based on the optimization objective and the first data. Alternatively, the accuracy information may be determined based on the first data and the second data. The second data may be data corresponding to the optimization objective after the second network element uses the recommended information. In other words, the second data may be a target that the second network element predicts can be achieved after using the recommended information. For example, if the recommended information is QoS parameters and the optimization objective is service experience, the first data may be the actual service experience, and the second data may be the predicted service experience that may be achieved using the recommended QoS parameters.

[0168] In some optional embodiments, method 400 includes: the second network element determines accuracy information according to the optimization target and the first data.

[0169] In some optional embodiments, the method 400 includes: the second network element determining the second data; and the second network element determining the accuracy information based on the first data and the second data. The second network element may determine the second data based on the recommendation information.

[0170] The accuracy information of the recommendation information may describe whether the recommendation information is accurate or reliable. For example, the higher the accuracy indicated by the accuracy information, the more accurate or reliable the recommendation information provided by the second network element is.

[0171] As an example, the accuracy of the recommendation information can be expressed as the difference between the optimization target and the first data. For example, if the optimization target is a service experience MOS greater than 4, and the first data after the first network element uses the recommendation information is a service experience MOS greater than 3.5, then the accuracy of the recommendation information is that the error in the service experience MOS is greater than 0.5.

[0172] As another example, the accuracy information of the recommendation information can be expressed as the frequency with which multiple first data reach the optimization target. For example, the optimization target is that the MOS of the service experience is greater than 4. The second network element can obtain N first data (N is a positive integer) after the first network element uses the recommendation information. Here, it is assumed that among the N first data, there are M first data greater than or equal to the optimization target (M is a positive integer less than or equal to N). Then, the accuracy information of the recommendation information can be M / N, and the value of M / N can be expressed as a percentage or as a decimal. In some optional implementation scenarios, the above-mentioned N first data can be obtained periodically after the first network element uses the recommendation information. For example, after the first network element uses the QoS parameters, the MOS of the service experience is sampled every 1 minute. In other optional implementation scenarios, the above-mentioned N first data can be N first data respectively obtained from the N UEs after the first network element applies the recommendation information to the N UEs.

[0173] As another example, the precision information of the recommended information can be expressed as the frequency with which multiple first data reach the optimization target. For example, the optimization target is that the MOS of the service experience is greater than 4. The second network element can obtain N first data after the first network element uses the recommended information. It is assumed that among the N first data, there are M first data that are greater than or equal to the optimization target. Then, the precision information of the recommended information can be M. When the precision information is expressed in frequency, the total number of first data obtained by the second network element (i.e., N) can be preset (for example, 100), or the total number can be indicated to the first network element. The precision information of the recommended information can also be expressed in other forms, which is not limited in this application.

[0174] This application does not limit the message that carries the accuracy information. For example, the accuracy information can be carried in an analysis notification message or an analysis response message, or in a recommendation notification message or a recommendation response message. The accuracy information can also be carried in other messages. Exemplarily, a recommendation notification message or a recommendation response message may include a recommendation result object, which may include accuracy information.

[0175] It should be noted that method 400 can be executed periodically. In some optional embodiments, S410 can be executed in each execution cycle, or only in the first execution cycle, or in any execution cycle, which is not limited by this application. The accuracy information can be the accuracy information of method 400 during the first execution, or the accuracy information of method 400 during any execution, which is not limited by this application.

[0176] Through the above embodiment, the second network element can send the accuracy information of the recommended information to the first network element. The accuracy information is determined based on the optimization target and the true value corresponding to the optimization target. Therefore, the above solution can monitor the accuracy of the recommended information. After receiving the accuracy information, the first network element can make a decision based on the accuracy information of the recommended information. For example, the first network element can suspend the use of the recommended information if the accuracy information is poor. For another example, the first network element can request updated recommended information from the second network element if the accuracy information is poor, so as to obtain recommended information with better accuracy information.

[0177] Optionally, in another implementation scenario of the above embodiment, the method 400 further includes: the second network element receiving first information from the first network element, where the first information can be used to request the accuracy information. Accordingly, the first network element sends the first information to the second network element.

[0178] Furthermore, the second network element may execute at least one of the above S410 to S440 according to the first information, or in response to the first information.

[0179] This application does not limit the message carried by the first information. For example, the first information may be carried in an analysis notification message or an analysis response message, or in a recommendation notification message or a recommendation response message. The first information may also be carried in other messages. For example, a recommendation subscription message or a recommendation request message may include a recommendation request object, which may include the first information.

[0180] In some optional embodiments, the first information may include recommendation accuracy request information, where the request information is used to instruct the second network element to provide accuracy information to the first network element. In other optional embodiments, the first information may have other names, such as recommendation accuracy request information or other names.

[0181] In some optional embodiments, the first information may further include a recommendation accuracy information time window, which is used to indicate a time period with a start and end time. The time window indicates that the first network element only considers accuracy information generated within the time period. The recommendation accuracy information time window may also have other names.

[0182] In some optional embodiments, the first information may further include a recommendation accuracy information periodicity, which is used to instruct the second network element to periodically send accuracy information corresponding to the recommendation information to the first network element, where the period is a value indicated by the recommendation accuracy information periodicity. The recommendation accuracy information periodicity may also have other names.

[0183] In some optional embodiments, the first information may further include a recommended accuracy threshold, including one or more thresholds. When the second network element detects that the accuracy information is less than or equal to the one or more thresholds, it may proactively send the accuracy information to the first network element. The recommended accuracy threshold may also have other names.

[0184] In some optional embodiments, the first information may further include an updated recommendation flag, indicating that if the second network element can generate new recommendation information within the above-mentioned recommendation accuracy information time window, the second network element may send the new recommendation information to the first network element.

[0185] In some optional embodiments, the first information or other information may include a recommendation information identifier to indicate the type of the recommendation information. For example, if the recommendation information identifier is QoS recommendation, it may indicate that the recommended information is a QoS parameter. This application does not limit the name of the recommendation information identifier. For example, the recommendation information identifier may be called an analytics ID or a recommendation registered ID.

[0186] In some optional embodiments, the first information or other information may include a recommendation flag, instructing the second network element to provide recommendation information to the first network element. The second network element may generate a recommendation result based on the recommendation flag according to a preset logic, method, or approach. For example, based on the recommendation flag, the second network element may determine that it is necessary to retrieve previously generated historical recommendation information and then generate new recommendation information based on the historical recommendation information.

[0187] In some optional embodiments, the first information may include an optimization target. In other words, the optimization target in S410 may be carried in the first information.

[0188] Through the above embodiment, the first network element can request the accuracy information of the recommended information from the second network element. Thus, the first network element can make a process based on the requested accuracy information.

[0189] Optionally, in another implementation scenario of the above embodiment, the method 400 further includes: the second network element receiving the second information from the first network element. Accordingly, the first network element sends the second information to the second network element.

[0190] Among them, the second information can be used to indicate whether the first network element uses the recommendation information, whether the first network element uses the recommendation information according to the specifications corresponding to the recommendation information, the conditions under which the first network element uses the recommendation information, the target object for which the first network element uses the recommendation information, or at least one of the effects of the first network element using the recommendation information.

[0191] It should be noted that whether the first network element uses the recommendation information may include whether the first network element has already used the recommendation information, and may also include whether the first network element is going to use the recommendation information.

[0192] This application does not limit the message that carries the second information. For example, the second information can be carried in an analysis notification message or an analysis response message, or in a recommendation notification message or a recommendation response message. The second information can also be carried in other messages. For example, a recommendation subscription message or a recommendation request message can include a recommendation request object, and the recommendation request object can include the second information.

[0193] This application does not limit the specific name of the second information. The second information can be recommendation feedback information or have other names. For example, the second information can be called feedback information, etc.

[0194] In some optional embodiments, the second information may include indication information indicating whether the recommendation information was used or will be used. This indication information may also have other names. It should be noted that this indication information may indicate whether all the recommendation information is used, or may indicate whether only part of the recommendation information is used.

[0195] In some optional embodiments, the second information may include instruction information for indicating whether the recommendation information is used in accordance with the specification of the recommendation information. The instruction information may also have other names. For example, the instruction information may indicate that the recommendation information is used in accordance with the specification of the recommendation information, or indicate that the recommendation information is not used in accordance with the specification of the recommendation information.

[0196] The specification of the recommended information may be an input parameter included in the request message when the first network element requests the recommended information. The input parameter included in the request message may be a parameter included in the subscription / request message in S210 or S310 above. For example, the specification of the recommended information may include a specific area, a specific slice, etc. For example, the recommended information is applicable to cell 1 and S-NSSAI1. If the first network element uses the recommended information in the above-mentioned cell 1 and S-NSSAI1, the second information may be used to indicate that the first network element uses the recommended information according to the specification corresponding to the recommended information. Otherwise, for example, if the first network element uses the recommended information in cell 2 and S-NSSAI2, the second information may be used to indicate that the first network element does not use the recommended information according to the specification corresponding to the recommended information.

[0197] The specification may also include at least one of a recommendation information identifier, a target, or recommendation filter information. For example, the recommendation filter information may be AOI, S-NSSAI, etc. The specification may also be called a recommendation specification or have other names.

[0198] In some optional embodiments, the second information may include indication information indicating conditions for using the recommendation. The indication information may also have other names. For example, if the first network element does not use the recommendation information in accordance with the specification, the actual usage conditions of the recommendation information may be indicated through the indication information. For another example, the first network element may indicate the actual usage conditions of the recommendation information through the indication information, and the second network element may determine whether the first network element uses the recommendation information in accordance with the specification based on the indication information. Exemplarily, the actual usage conditions may include a timestamp, a time window, an AOI, an S-NSSAI, or an application ID, etc.

[0199] In some optional embodiments, the second information may include indication information indicating a target object for using the recommendation. The first network element may indicate the target object used for the recommendation result, for example, one or more SUPIs, internal group identifiers, or any UE. The indication information indicates that the first network element actually uses the recommendation information for one or more UEs. For example, the PCF may set the QoS parameters of one or more UEs based on the QoS parameters recommended by the second network element. For another example, the recommendation information is a UPF, and the SMF may determine the UPF based on the recommendation information, wherein the determined UPF may carry data transmission for one or more UEs. For another example, the recommendation information is an avoidance timer, and the AMF may configure the avoidance timer for one or more UEs.

[0200] In some optional embodiments, the second information may include indication information indicating the effectiveness for using the recommendation. The indication information may also have other names. If the recommendation is used, the first network element may provide feedback to the second network element via the second information on the effectiveness of the recommendation. For example, the indication information may indicate whether the desired optimization goal is achieved after using the recommendation.

[0201] Through the above embodiment, the first network element can send feedback information about recommended information to the second network element. The second network element can then process the information based on the feedback. For example, if the first network element does not use the recommended information or does not use it in accordance with specifications, the second network element can analyze the cause and provide more appropriate recommended information. For another example, based on the actual conditions, goals, or effects of the first network element's use of the recommended information, the second network element can provide more appropriate recommended information.

[0202] Optionally, in another implementation scenario of the above embodiment, S440 includes: when the first network element uses the recommendation information according to the specification corresponding to the recommendation information, the second network element sends the accuracy information of the recommendation information to the first network element.

[0203] In other words, the second network element may determine whether to provide the accuracy information to the first network element based on the feedback information from the first network element. In some optional embodiments, the second network element provides the accuracy information to the first network element when the first network element uses the recommended information according to the specification corresponding to the recommended information, without the first network element explicitly requesting (e.g., sending the above-mentioned first information).

[0204] Through the above embodiment, the first network element can send feedback information of the recommendation information to the second network element. In the case where the feedback information indicates that the first network element uses the recommendation information according to the specification corresponding to the recommendation information, the second network element can respond to the feedback information and send accuracy information of the recommendation information to the first network element.

[0205] In other optional embodiments, when the first network element does not use the recommendation information, or when the first network element does not use the recommendation information according to the specification corresponding to the recommendation information, the second network element may not determine the accuracy information of the recommendation information, or the second network element may not send the accuracy information to the first network element, or in other words, the second network element may not perform accuracy monitoring of the recommendation information.

[0206] It should be noted that the above solution can be understood as the first network element implicitly instructing the second network element to perform accuracy monitoring of the recommendation information. However, this application does not limit the form of implicit instruction, and implicit instruction can also take other forms. For example, the first network element sends information about the use effect of the recommendation information to the second network element. When the second network element receives the use effect information from the first network element, it assumes that the first network element has used the recommendation information according to the specification corresponding to the recommendation information, and thus performs accuracy monitoring.

[0207] Optionally, in another implementation scenario of the above embodiment, S430 includes: the second network element sending a first request to the first network element, the first request being for requesting the first data; the second network element receiving the first data from the first network element. Correspondingly, the first network element receives the first request from the second network element; and the first network element sending the first data to the second network element.

[0208] This application does not limit the message carried by the first data sent by the first network element. The first data may be carried in the aforementioned second information. This application does not limit the message carried by the first request; the first request may be carried in any message. This application does not limit the specific name of the first request; the first request may also be referred to as indication information or have other names.

[0209] Optionally, in another implementation scenario of the above embodiment, S430 includes: the second network element sending a second request to the first device, the second request being for the first data; the second network element receiving the first data from the first device, wherein the first device includes at least one of an application function network element, a network function network element, a network management system, or a terminal device. Accordingly, the first device receives the second request from the second network element; and the first device sends the first data to the second network element.

[0210] Exemplarily, the application function network element may be an AF, the network function network element may be an NF, the network management may be an OAM, and the terminal device may be a UE. For example, if the optimization goal is service experience and the QoS parameters of the recommended information are service experience parameters, the second network element may receive service experience information from the AF. For another example, the second network element may receive service experience information from the UPF. For another example, if the recommended information is the UPF and the optimization goal is the UPF load, the second network element may receive load information from the OAM. For another example, if the recommended information is a UE under attack, the second network element may receive first data from the UE, where the first data indicates whether the UE is under attack.

[0211] Optionally, in another implementation scenario of the above embodiment, the method 400 further includes: the second network element sending third information to the first network element. Correspondingly, the first network element receives the third information from the second network element.

[0212] The third information may be used to indicate that the accuracy information is determined based on the optimization objective and the first data. Alternatively, the third information may indicate that the accuracy information is determined based on the first data and the second data. The second data may be data of the optimization objective predicted by the second network element after using the recommended information. In other words, the second data may be a target that can be achieved after using the recommended information as predicted by the second network element. For example, if the recommended information is a QoS parameter and the optimization objective is a service experience, the first data may be the actual service experience, and the second data may be the predicted service experience that may be achieved using the recommended QoS parameters.

[0213] In other words, the third information may indicate a calculation method of the accuracy information of the recommendation information.

[0214] In some optional embodiments, the third information may further indicate a failure in calculating the accuracy information of the recommendation information, and optionally indicate a cause code for the failure. For example, the third information may indicate that the cause of the failure is that the conditions and / or target of using the recommendation are changed.

[0215] This application does not limit the name of the third information. For example, the third information can be called feedback information or have other names.

[0216] This application does not limit the message in which the third information is carried. For example, the third information may be carried in an analysis notification message or an analysis response message, or in a recommendation notification message or a recommendation response message. The third information may also be carried in other messages. For example, a recommendation notification message or a recommendation response message may include a recommendation result object, which may include the third information.

[0217] Through the above embodiment, the second network element can send the calculation method of the accuracy information to the first network element, thereby assisting the first network element in determining the confidence level of the accuracy information, so that the first network element can make processing based on the accuracy information.

[0218] The above embodiment can be understood as the second network element determining a method for calculating accuracy information and notifying the first network element of the method, but this application is not limited to this. In other optional embodiments, the first network element may send the method for calculating accuracy information to the second network element. For example, the first network element may instruct the second network element to determine accuracy information based on the optimization objective and the first data. For another example, the first network element may instruct the second network element to determine accuracy information based on the first data and the second data.

[0219] Optionally, in another implementation scenario of the above embodiment, the method 400 further includes: if the accuracy information does not meet the first condition, the second network element updates the recommendation information; the second network element sends the updated recommendation information to the first network element. Accordingly, the first network element receives the updated recommendation information from the second network element.

[0220] The first condition may be preset, or determined according to a preset rule, or the first condition may come from the first network element or other device. This application does not limit the name of the first condition. For example, the first condition may be called an accuracy condition or have other names.

[0221] The first condition may be a threshold value or a threshold range. For example, the first condition may be that the accuracy information is less than, greater than, or equal to a certain value. For another example, the first condition may be that the accuracy information is within a certain value range.

[0222] In some optional embodiments, if the accuracy information does not meet the first condition, the second network element redetermines the accuracy information, that is, updates the accuracy information. If the accuracy information meets the first condition, the second network element does not redetermine the accuracy information, that is, does not update the accuracy information.

[0223] In some optional embodiments, if the update recommendation flag in the aforementioned first information indicates that an update is possible, then, in response to the first information, the second network element may send updated recommendation information to the first network element if the accuracy information does not meet the first condition. If the update recommendation flag in the aforementioned first information indicates that an update is not possible, then the second network element may not re-determine the accuracy information, that is, may not update the accuracy information.

[0224] This application does not limit the message carried by the updated recommendation information. For example, the updated recommendation information can be carried in the updated recommendation in the third information.

[0225] Through the above embodiment, when the accuracy information does not meet the conditions, the second network element can send updated recommendation information to the first network element, thereby realizing accuracy monitoring of the recommendation information and providing more accurate recommendation information, thereby improving the quality of the recommendation information.

[0226] In some optional embodiments, the above S440 includes: the second network element sending first precision information of the recommendation information to the first network element. The method 400 also includes: the second network element sending second precision information of the recommendation information to the first network element, wherein the first precision information is different from the second precision information.

[0227] The second network element may continuously or periodically perform accuracy monitoring of the recommendation information. The second accuracy information may be accuracy information sent by the second network element after the second network element sends the first accuracy information.

[0228] In some optional embodiments, the method 400 further includes: the second network element sending a cause of accuracy change to the first network element.

[0229] For example, the reason for the change in the accuracy information may be that the usage conditions or usage targets of the recommendation information have changed, resulting in a change in the accuracy information.

[0230] Optionally, in another implementation scenario of the above embodiment, the method 400 further includes: the second network element sending capability information to the network storage function network element, where the capability information is used to indicate a recommendation accuracy checking capability.

[0231] Exemplarily, the network storage function network element may be an NRF.

[0232] The capability information may indicate that the second network element has the capability to check the accuracy of the recommendation information. A network element having the capability to check the accuracy of the recommendation information is capable of checking the accuracy of the recommendation information, or is capable of performing the actions that the second network element is capable of performing in the above method, or is capable of determining the accuracy of the recommendation information, or is capable of sending the accuracy of the recommendation information.

[0233] This application does not limit the specific name of the recommendation information accuracy check capability. For example, the recommendation information accuracy check capability can be called accuracy monitoring capability, recommendation information monitoring capability, recommendation information checking capability, or other names.

[0234] The second network element may register its information with the network storage function network element. In some optional embodiments, the second network element may send the network element type, network element address, supported service operations, and the above-mentioned capability information of the second network element to the network storage function network element through a network element management registration (e.g., Nnrf_NFManagement_NFRegister) service operation. In other optional embodiments, the second network element may send information indicating that the second network element does not have the recommended information accuracy check capability to the network storage function network element through a network element management registration service operation.

[0235] Optionally, in another implementation scenario of the above embodiment, the method 400 also includes: the first network element sends a network element discovery request to the network storage function network element, the network element discovery request includes the recommended information accuracy check capability, and the network element discovery request is used to request the discovery of a third network element with the recommended information accuracy check capability; the first network element receives a network element discovery response from the network storage function network element, the network element discovery response includes information of one or more of the third network elements; the first network element determines the second network element among the one or more third network elements.

[0236] For the network element discovery request, in some optional embodiments, the first network element may send a network element discovery request to the network storage function network element through a network function discovery request (e.g., Nnrf_NFDiscovery_Request) service operation.

[0237] This application does not limit the message carried by the network element discovery request. The network element discovery request can be carried in the network function discovery request message or in other messages.

[0238] In some optional embodiments, the network element discovery request further includes one or more target NF service names (one or more target NF service name / names). For example, the target NF service name can be an analysis subscription message or an analysis request message.

[0239] In some optional embodiments, the network element discovery request further includes the network element type of the target NF (NF type of the target NF). For example, the network element type of the target NF may include NWDAF or other types.

[0240] In some optional embodiments, the network element discovery request further includes the network element type of the NF service consumer. For example, the network element type of the consumer may include PCF or other types.

[0241] Regarding the network element discovery response, in some optional embodiments, the network storage function network element may send a network element discovery response to the first network element through a network function discovery response (e.g., Nnrf_NFDiscovery_Request Response) service operation.

[0242] For purposes of distinction, a third network element is a network element with the recommended information accuracy check capability requested by the network element discovery request, and a third network element is one or more network elements with the recommended information accuracy check capability reported back by the network element discovery response. A second network element is one or more network elements selected by the first network element from at least one third network element.

[0243] The information of the one or more third network elements may be identifiers of the one or more third network elements, or network addresses of the one or more third network elements, such as IP addresses. In other words, the one or more third network elements may include identifiers of the one or more third network elements and / or network addresses of the one or more third network elements.

[0244] It should be noted that the second network element may not be discovered by the first network element through the network storage function network element. In other optional embodiments, the first network element is locally configured with information about one or more third network elements capable of verifying the accuracy of the recommended information. In this way, the first network element can determine the second network element based on its own information without sending a network element discovery request to the network storage function network element.

[0255] For example, the NF may include AMF, SMF, UPF, or OAM. It should be noted that the NWDAF may also send the above request message to the AF or the user. In the case where the AF is a third party and the network does not trust the AF, the NWDAF may send the request message to the AF through the NEF.

[0256] In some optional embodiments, the NWDAF may send a request message to the NF via an event exposure subscription (e.g., Nnf_EventExposure_Subscribe) service operation. The request message may include an event ID. The event ID may indicate the data that the NWDAF is requesting or collecting. For example, if the event ID is service experience information, the service experience information that the NWDAF is to collect is identified as the first data.

[0257] S550: The NWDAF receives a notification message from the NF, where the notification message may include first data.

[0258] In some optional embodiments, the NF may send a notification message to the NF via an event disclosure notification (eg, Nnf_EventExposure_Notify) service operation. In the case where the AF is a third party, the AF needs to send a notification message to the NWDAF via the NEF.

[0264] S610: The user selects one NWDAF from one or more NWDAFs, and sends a second subscription / request message to the selected NWDAF.

[0265] Before S610, method 600 may include S510 and S520. It should be noted that if the user can locally configure the information of the NWDAF with the recommendation information accuracy check capability, then the above S510 and S520 do not need to be executed.

[0266] The second subscription message may be an analysis subscription message or a recommendation subscription message. The second request message may be an analysis request message or a recommendation request message.

[0269] As an example, if the user uses the recommended information in accordance with the specification, NWDAF determines to perform accuracy monitoring of the recommended information. As another example, if the user does not use the recommended information, or does not use the recommended information in accordance with the specification, NWDAF determines not to perform accuracy monitoring of the recommended information.

[0270] In the case where the NWDAF performs accuracy monitoring of the recommendation information, the method 600 further includes S540 to S570. In the case where the NWDAF does not perform accuracy monitoring of the recommendation information, the method 600 may not include S540 to S570.

[0277] As an example, when the second information includes the first data, NWDAF can determine the accuracy information based on the first data and the optimization target. As another example, when the second information includes the accuracy information, NWDAF can determine the accuracy information based on the second information. In other words, NWDAF can obtain the accuracy information. NWDAF does not need to perform additional calculations.

[0278] In some optional embodiments, the method 700 further includes: the NWDAF determines whether to update the recommendation information according to the accuracy information. If the NWDAF updates the recommendation information, the method 700 may further include S570.
