The embodiments of the present application provide a data processing method and device. The data analysis network element can analyze data of a roaming terminal. Detailed descriptions are given below.

In the data processing system, as shown in Figure 1, the data analysis network element can collect and analyze the data generated by the functional network element to the terminal. After the analysis result is obtained, the analysis result will be returned to the functional network element. In the embodiments of the present application, the data analysis network element may be a network data analysis function (NWDAF) network element, and a management data analysis service (management data analysis service, MDAS) network element. Functional network elements may include network function (NF) network elements, application function (AF) network elements, operation management and maintenance (operation, administration, and maintenance, OAM) network elements or terminals, etc.

NF network element refers to the module or entity that performs certain or certain specific functions in the operator's network, and can include access and mobility management function (AMF) network elements, radio access network ( radio access network (RAN) network element, session management function (SMF) network element, user plane function (UPF) network element, policy control function (PCF) network element, etc.

Operation management and maintenance network elements refer to network elements that include at least one of the following functions: network resource deployment functions, network operation management or maintenance functions.

The application function network element refers to a network element that includes at least one of the following functions: the function of processing service-related signaling and media data, and the QoS authorization interaction function of the service with the network side.

A terminal (also referred to as user equipment (UE)) is a device with wireless transceiver functions, which can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; or on the water (such as ships, etc.) ); It can also be deployed in the air (for example, on airplanes, balloons, and satellites). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, and an industrial control (industrial control) Wireless terminals in, self-driving (self-driving), wireless terminals in remote medical, wireless terminals in smart grid, wireless terminals in transportation safety, Wireless terminals in a smart city, wireless terminals in a smart home, etc.

Data analysis network elements, such as: NWDAF or MDAS can collect data from AF network elements, NF network elements, OAM network elements, or terminals, or store the collected data in a data warehouse, and then from the data warehouse when analysis is needed Obtain the corresponding data for analysis. After the data analysis network element obtains the analysis result, it can send the analysis result to the AF network element, NF network element, OAM network element or terminal. In this way, the AF network element, NF network element, OAM The network element or terminal can execute corresponding strategies according to the corresponding analysis results, for example: enhancement of UPF selection or enhancement of quality of service (QoS) parameter generation.

What kind of enhancement operations the AF network element, NF network element, OAM, or terminal does is to improve the service quality of the terminal, and the data processing method provided in this embodiment of the application is for roaming terminals. Roaming here refers to the broad concept of roaming, including the following two meanings: On the one hand, it refers to the terminal moving from one public land mobile network (PLMN) to another PLMN, such as: roaming from China Mobile network to the United States AT&T network; on the other hand, it refers to the terminal moving from one area to another in the same PLMN, such as moving from one NWDAF service area to another NWDAF service area, or such as: roaming from China Mobile Beijing area to China Mobile Shanghai area . Regardless of the above roaming meaning, the destination network or destination area to which the terminal moves can be called the visited place, and the source network or source area of the terminal is called the home place. Generally, a PLMN will have many data analysis network elements. Taking the data analysis network element as NWDAF as an example, as shown in Figure 2A and Figure 2B, these NWDAFs can be deployed according to the architecture of the country, province, and city. The terminals can be deployed in different locations. Roaming between NWDAF. During the terminal roaming process, the NWDAF that performs data processing for the roaming terminal may be different. For example, as shown in FIG. 2A: if a terminal roams from one country to another country, the NWDAF that performs data processing on the roaming terminal is a PLMN-level NWDAF. For example, as shown in Figure 2B, if the roaming terminal roams from one province to another province in the same PLMN, the NWDAF that performs data processing on the roaming terminal is the NWDAF belonging to the province level. If the roaming terminal roams from a city in a province to another city in the province, such as roaming from Shenzhen, Guangdong Province to Heyuan City, the NWDAF that performs data processing on the roaming terminal is a city-level NWDAF.

No matter which level of roaming the roaming terminal belongs to, the NWDAF of the terminal's visited place can be called visited NWDAF, or it can be called the first data analysis network element. The NWDAF of the home location of the terminal may be called home-NWDAF, or it may be called the second data analysis network element. Normally, the process of NWDAF performing data processing is initiated based on the request of the functional network elements listed above. Therefore, the functional network element belonging to the visited place can be called the visited functional network element, or it can be called the first functional network element. A functional network element. Correspondingly, the functional network element of the home location of the roaming terminal may be referred to as a home functional network element or as a second functional network element.

The following describes the data processing method provided by the embodiment of the present application with reference to FIG. 3.

As shown in FIG. 3, an embodiment of the data processing method provided by the embodiment of the present application may include:

101. The first functional network element sends a first request to the first data analysis network element, and correspondingly, the first data analysis network element receives the first request sent by the first functional network element.

The first request is used to request a first analysis result of the terminal. The first request is triggered by the first functional network element based on the terminal roaming under the network coverage of the first functional network element. For example, when the first functional network element is AMF, the first functional network element may be receiving roaming The first request is triggered after the registration request sent by the terminal. For another example, when the first functional network element is an SMF, the first functional network element may trigger the first request after receiving the session establishment request sent by the roaming terminal.

The first analysis result refers to the data analysis result generated by the first data analysis network element of the visited place of the roaming terminal for the roaming terminal.

The terminals here include a single terminal or a group of terminals.

The first analysis result may be an analysis result for a terminal.

The first analysis result may also be an analysis result of a roaming terminal group to which the terminal belongs.

When the first analysis result is the analysis result of the roaming terminal group to which the terminal belongs, the method for generating the first analysis result may be: first generate a third analysis result for each terminal in the group, for example: If there are N roaming terminals, there are N third analysis results. Then, the first analysis result is generated according to the N third analysis results. The third analysis result refers to the data analysis result generated by the first data analysis network element of the visited place for the single roaming terminal in the visited place. The first analysis result may be a common feature extracted from the N third analysis results.

102. The first data analysis network element determines that the terminal is a roaming terminal.

After the first data analysis network element receives the first request, it will first determine whether the terminal is a roaming terminal, and perform subsequent operations if it is a roaming terminal.

There may be multiple methods for the first data analysis network element to determine whether the terminal is a roaming terminal, for example:

In a possible implementation manner, the first request includes second indication information or/and the home location identification information of the terminal, and the second indication information is used to indicate that the terminal is a roaming terminal; the first data The analyzing network element may determine that the terminal is a roaming terminal according to the second indication information or/and the home location identification information of the terminal. Specifically, the first data analysis network element may determine that the terminal is a roaming terminal by comparing the identification information of the home location of the terminal with the identification information of the visited location of the terminal. For example, a comparison finds that the terminal PLMN identification information is different from the PLMN identification information corresponding to the first data analysis network element, or the identification information ID of the data analysis network element where the terminal belongs is different from the identification information of the first data analysis network element, or the terminal is located The area of the attribution is different from the area of the first data analysis network element.

The home location identification information of the terminal includes one or more of the following information: the public land mobile network PLMN identification information of the home location, the identification information of the data analysis network element of the home location, and the area information of the home location. For example, in a possible implementation manner, when the terminal roams from one PLMN to another PLMN, the terminal's home location identification information includes the home location PLMN identification information, and optionally, the home location data analysis network element identification information Or the area information of the attribution. In another possible implementation, when a terminal roams from one area to another in the same PLMN, the terminal’s home location identification information includes the identification information of the data analysis network element of the home location or the area information of the home location, And it may include or not include the PLMN identification information of the attribution, which is not limited.

In a possible implementation manner, the first request may include the identification of the terminal, and the first data analysis network element may use the identification of the terminal to determine the attribution of the terminal in the network, if the attribution is not of the first data analysis network element Where it belongs, it can be determined that the terminal is a roaming terminal. Specifically, the first data analysis network element may obtain the data reported by other functional network elements in the network, and obtain the terminal attribution identifier associated with the terminal identifier from these data, and then determine the attribution of the terminal according to the terminal attribution identifier The place is not the place where the first data analysis network element belongs. For example, the first request includes the terminal ID, the first data analysis network element can obtain the HPLMN ID associated with the terminal ID from the AMF, and the first data analysis network element is different from the ID of the PLMN where the terminal is located according to the HPLMN ID of the terminal. It is determined that the terminal is a roaming terminal. Of course, it is also possible to determine that the terminal is a roaming terminal in other ways, which is not limited in the embodiment of the present application.

103. The first data analysis network element generates the first analysis result of the terminal according to the first request.

In the embodiment of the present application, the first data analysis network element may generate the first analysis result of the terminal in many ways, such as:

A possible implementation manner may be: Step 1021 is performed before step 103: The first data analysis network element receives the first data from the terminal of the second functional network element, and the second functional network element belongs to The visiting place where the terminal is located; accordingly, step 103 is: the first data analysis network element generates the first analysis result according to the first data.

The second functional network element may be an NF network element, an AF network element, an OAM network element, or a terminal belonging to the visited place described above. The first data refers to the process/result data generated in the terminal itself, the visited network, the business server in the visited place, etc. when the terminal executes the mobility process or the session process in the visited network. The first data can be business-related data or other types of data. The type of the first data is related to the first analysis result. There can be multiple analysis results. The first data is based on the content contained in different analysis results. It will be different.

For example, when the first analysis result is the service experience analysis result of a certain application (such as service MOS of the application), the first data is the data types listed in Table 1 and Table 2 below.

Table 1: Business data collected by NWADF from the visited AF

Table 2: Network data collected by NWDAF from the visited NF or OAM network elements

A possible implementation may be: Step 1022 is performed before step 103: The first data analysis network element receives the second data from the terminal of a third function network element, and the third function network element belongs to The home location of the terminal;

Correspondingly, step 103 is: the first data analysis network element generates the first analysis result according to the second data.

The third functional network element may be the NF network element, AF network element, OAM network element, etc. belonging to the home area described above. The second data refers to the process/result data generated in the home network, home service server, etc. when the terminal executes the mobility process or the session process in the visited network. The second data can be business-related data or other types of data. The type of the second data is related to the first analysis result. There can be multiple analysis results. The second data is based on the content contained in different analysis results. It is also different, please refer to the explanation of the first data for details.

A possible implementation manner may be: step 1023 is performed before step 103: the first data analysis network element receives the second analysis result from the terminal of the second data analysis network element or the first data storage network element , The second data analysis network element or the first data storage network element belongs to the attribution of the terminal.

Correspondingly, step 103 is: the first data analysis network element generates the first analysis result according to the second analysis result.

In a possible implementation manner, the first analysis result can also be generated through a combination of the above-mentioned first data, second data, and second analysis result. Such as:

A first analysis result is generated based on the first data and the second data.

The first analysis result is generated based on the first data and the second analysis result.

The first analysis result is generated based on the second data and the second analysis result.

The first analysis result is generated according to the first data, the second data, and the second analysis result.

Of course, the method for obtaining the first data, the second data, and the second analysis result is the same as the method described in the above-mentioned possible implementation manner, and will not be repeated in the combination manner.

In a possible implementation manner, the second analysis result is an analysis result generated by the second data analysis network element on the terminal or a roaming terminal group to which the terminal belongs at the home location. In other words, the second analysis result is the analysis result generated by the second data analysis network element analyzing the relevant data generated by each functional network element in the home location of the terminal for the terminal. Specifically, the analysis result type corresponding to the second analysis result is the same as the analysis result type corresponding to the first analysis result. For example, the first analysis result refers to the service MOS analysis of the NWDAF of the visited place on the application 1 of a terminal As a result, the second analysis result refers to the service MOS analysis result of the application 1 of the terminal by the NWDAF at the home location.

In a possible implementation manner, the second analysis result is an analysis result generated by the first data analysis network element on the terminal or a roaming terminal group to which the terminal belongs in the visited place. To illustrate, the second analysis result is that the first data analysis network element once generated the terminal or the roaming terminal group to which the terminal belongs in the visited place and sends the analysis result stored in the home place of the roaming terminal group.

The second analysis result is an analysis result generated by the fourth data analysis network element on the terminal or the roaming terminal group to which the terminal belongs in the visit place corresponding to the fourth data analysis network element, wherein the fourth data The visited place corresponding to the analysis network element is different from the visited place corresponding to the first data analysis network element or the second data analysis network element. To illustrate one point, the second analysis result is that the fourth data analysis network element once generated the terminal or the roaming terminal group to which the terminal belongs in the visited place, and sends the analysis result stored in the home place of the roaming terminal group.

The fourth data analysis network element here is only to express the data analysis network element of the visited place that the terminal or the roaming terminal group to which the terminal belongs has visited. In fact, the third data analysis network element and the fifth data analysis network can also be used. Yuan, etc., the number "fourth" has no special meaning.

Wherein, the method of obtaining the second analysis result may be:

The first data analysis network element determines the second data analysis network element or the first data storage network element according to the attribution identification information of the terminal.

Sending, by the first data analysis network element, a second request to the second data analysis network element or the first data storage network element, the second request being used to request the second analysis result;

The first data analysis network element receives a second response sent by the second data analysis network element or the first data storage network element, and the second response includes the second analysis result.

Wherein, the second request may also include visited place identification information of the visited place where the terminal is located. The identification information of the visited place may indicate the source of the second request.

The visited place identification information includes one or more of the following information: the public land mobile network PLMN identification information of the visited place, the identification information of the data analysis network element of the visited place, the area information of the visited place, and the area information of the visited place It can refer to the area of the visited place, such as Shenzhen in Guangdong Province. For example, in a possible implementation manner, when the terminal roams from one PLMN to another PLMN, the visited place identification information of the terminal includes the PLMN identification information of the visited place, and optionally, also includes the identification information of the visited place data analysis network element Or the area information of the visited place. In another possible implementation manner, when the terminal roams from one area to another in the same PLMN, the terminal's visited place identification information includes the identification information of the visited place data analysis network element or the visited place area information, and its The PLMN identification information of the visited place may be included or not, and it is not limited.

The identification information of the data analysis network element in the visited place is used to uniquely identify the data analysis network element in the visited place that provides data analysis services for the terminal.

The data type of the first data and the second data is related to the required first analysis result. For example, the request is the analysis result related to the service of the terminal. The first data and the second data are directly or indirectly related to the service in the relevant functional network element. Relevant data; if the analysis result related to the abnormal behavior of the terminal is requested, the first data and the second data are the data directly or indirectly related to the abnormal user behavior in the relevant functional network element; if the request is other types of analysis As a result, the first data and the second data are corresponding types of data.

The above description of the second analysis result is the analysis result obtained by analyzing the data of the attribution place. In fact, the second analysis result can also be the analysis result of the place visited by the terminal, and the data analysis result is the result of the terminal visited. The data analysis network element of the visited place is generated and sent to the home place for storage. For example, the home location of the terminal is the Shanghai area, and the terminal currently roams to the Beijing area, and the terminal also roams to the Guangdong area before that, the second analysis result may also be the analysis result of the Guangdong area. It should be noted that the place visited by the terminal in the past may be the same as or different from the place visited currently. Take for example that the place visited before can be different from the place visited currently:

The second analysis result is an analysis result generated by the fourth data analysis network element on the terminal or the roaming terminal group to which the terminal belongs in the visit place corresponding to the fourth data analysis network element, wherein the fourth data The visited place corresponding to the analysis network element is different from the visited place corresponding to the first data analysis network element or the second data analysis network element. The fourth data analysis network element sends the second analysis result generated by the fourth data analysis network element to the second data analysis network element or the first data storage network element for storage.

In this case, the second response further includes the visited place identification information corresponding to the fourth data analysis network element, and the visited place identification information corresponding to the fourth data analysis network element may indicate that the second analysis result is determined by the fourth data analysis network element. The visited place corresponding to the data analysis network element is generated for the terminal.

The foregoing process of obtaining the second analysis result has been described. The second analysis result may be included in the second response, and the second response may also include the identification information of the attribution of the terminal. The home location identification information is used to indicate that the second analysis result comes from the home location.

In the second response, the second data analysis network element or the first data storage network element sends the analysis result of the visited place or the analysis result of the home place, which can be implemented in multiple ways. For example, in a possible implementation, if there is an analysis result of the place visited, the analysis result of the place visited will be sent first; if there is no further analysis result of the home place; if there are neither, then send An empty message may indicate that there is no secondary analysis result. For another example, in another possible implementation, when there is both the analysis result of the visited place and the analysis result of the attribution, both can be sent at the same time. For another example, in another possible implementation manner, it is also possible to distinguish in detail whether the visited place that the terminal once visited is the visitor place where the terminal is currently located, and the following analysis results are sent as the second analysis result according to priority from high to low : The visited place where the terminal is currently located has produced analysis results for the terminal, the home place has produced analysis results for the terminal, other visited places have produced analysis results for the terminal, an empty message or indicates that there is no second analysis result. Of course, there are other specific implementation manners, which will not be listed here.

104. The first data analysis network element sends a first response to the first functional network element, and accordingly, the first functional network element receives the first response.

The first response includes the first analysis result, the first response also includes first indication information or the attribution identification information of the terminal, and the first indication information is used to indicate the first data analysis result It is generated for a roaming terminal, and the home location identification information is used to indicate that the first data analysis result is generated for a terminal at the home location.

The first response also includes visitor location identification information of the visitor location where the terminal is located. The visited place identification information is used to indicate that the first analysis result is generated for the terminal roaming to the visited place.

Optionally, step 105 may be included after step 104.

105. The first data analysis network element sends the first analysis result to a second data analysis network element or a first data storage network element.

The foregoing embodiment describes the data processing process after the terminal roams as a whole. The data processing method provided by the embodiment of the present application is further described below in conjunction with FIG. 4 and FIG. 5.

Because there are many English abbreviations involved in the embodiment corresponding to FIG. 4 and FIG. 5, the English abbreviations are introduced accordingly.

Compared with the terminal, the contracted place of the terminal is the home place, and the visited place after the terminal roams is the visited place.

The PLMN of the attribution is H-PLMN, the NWDAF of the attribution is H-NWDAF, and the NF/AF/OAM of the attribution are H-NF/H-AF/H-OAM, respectively. Unified data management of the attribution , UDM)/user data repository (UDR) is H-UDM/H-UDR.

The PLMN of the visited place is V-PLMN, the NWDAF of the visited place is V-NWDAF, the AMF of the visited place is V-AMF, and the NF/AF/OAM of the visited place is V-NF/V-AF/V-OAM. The UDM/UDR is V-UDM/V-UDR.

It should be noted that in the scenarios described in Figures 4 and 5 below, the network elements in the 5G scenario are used as an example for description. In fact, the solutions provided in the embodiments of this application are also applicable to, for example, 4G or future 6G. System or network.

It should be noted that the scenarios described in Figures 4 and 5 below are scenarios when the terminal is roaming between two PLMNs. In fact, this method is also suitable for terminals in different areas of the same PLMN or between different NWDAFs. Roaming scene. The only difference is that the meanings of the attribution and the visit in the two scenarios are different. In the former, the attribution generally refers to the attribution PLMN, and the visit generally refers to the visited PLMN; and the attribution in the latter generally refers to the attribution area. Generally refers to the visited area. Correspondingly, the home location identification information and visited location identification information involved in the two scenarios will be slightly different. For details, see step 102 for the description of the home location identification information corresponding to the two scenarios, and step 103 for the two scenarios respectively. Description of the identification information of the visited place. In addition, FIGS. 4 and 5 take the data analysis network element as an example of NWDAF for illustration. In fact, the data analysis network element may be other network elements with equivalent functions, such as MDAS.

As shown in FIG. 4, another embodiment of the data processing method provided in the embodiment of the present application may include:

201. The terminal roams from the H-PLMN to the V-PLMN, and initiates a registration process to the V-AMF network element.

In the embodiment of this application, the home network of the terminal is H-PLMN, and the network to which the terminal roams is V-PLMN.

The terminal initiates a registration process to the V-AMF network element, requesting registration in the V-PLMN.

202. The V-AMF may determine that the terminal is a roaming terminal according to the identification information of the terminal.

The AMF of the V-PLMN can be through the terminal’s international mobile subscriber identity (IMSI), subscription permanent identifier (SUPI), or globally unique temporary user equipment identity (globally unique UE Identity, GUTI), Identification information such as a generic public subscription identifier (GPSI) determines that the terminal is a roaming terminal.

In this step 202, the V-AMF can directly determine that the terminal is a roaming terminal according to the identification information of the terminal. For example, the identification information of the terminal is compared with the identification information of the locally subscribed terminal. If the identification information of the terminal is not available Within the identification information of the locally subscribed terminal, it is determined that the terminal is a roaming terminal.

It is also possible to indirectly determine that the terminal is a roaming terminal based on the identification information of the terminal. For example, V-AMF can determine whether the terminal is a roaming terminal according to the PLMN ID corresponding to the terminal identification information. For example, when the PLMN ID corresponding to the terminal identification information and its own location If the PLMN ID of the network is different, it is determined that the terminal is a roaming terminal.

203. The V-AMF requests the H-UDM/H-UDR for subscription data of the terminal.

The subscription data can include the H-NWDAF identification information corresponding to the terminal, as well as the H-PLMN ID information and the terminal's home area information, that is, the specific area that the terminal belongs to in the HPLMN, and the area can have a network area identification (TAI, TAI list, cell ID list, etc.), or geographic area identification (Shanghai, Beijing, etc.), the contract data is sent to the V-AMF by the H-UDR/H-UDM of the H-PLMN.

In addition, the H-NWDAF identification information can have different manifestations, for example, it can be directly identified by the H-NWDAF ID, or indirectly identified by the H-NWDAF service area.

204. The V-NF/V-AF/V-OAM in the V-PLMN sends the first request to the V-NWDAF.

The first request may also be sent by the terminal itself.

The V-NF/V-AF/V-OAM/terminal in the VPLMN needs to obtain the first analysis result related to the roaming terminal from the V-NWDAF for some reason, for example: in order to select the PDU session initiated by the roaming terminal If the appropriate UPF, the SMF in the V-PLMN needs to obtain the service behavior analysis result for the roaming terminal from the V-NWDAF, the V-SMF sends the first request to the V-NWDAF to request the service behavior analysis result of the roaming terminal .

The first request may be a subscription message or an instant request message.

In a possible implementation manner, when the V-AMF sends the first request to the V-NWDAF, the above steps 201-203 can determine that the terminal is a roaming terminal and obtain the subscription data of the terminal. In another possible implementation, when it is not V-AMF, but other V-NF/V-AF/V-OAM/terminals send the first request to V-NWDAF, other V-NF/V-AF/ The V-OAM/terminal can obtain the above-mentioned related information of the terminal from the V-AMF.

The first request includes an analysis result type identifier (such as analytic ID) or an event identifier (such as event ID), which is used to indicate the type of the first analysis result specifically requested. For example, the analytical ID is: service mean opinion score (service MOS), terminal abnormal behavior (UE abnormal behavior), user plane function network element (user plane function, UPF) download (load) event, etc.

In a possible implementation manner, the first request may also include an analysis result or an event filter condition (such as analytic/event filter), which is used to indicate that the specific request is the first analysis result that meets the filter condition. For example, the filter conditions are: time filter conditions, area filter conditions, business type filter conditions, slice filter conditions, DNN filter conditions, etc.

In a possible implementation manner, the first request may also include analysis object information, which is used to indicate that the specific request is the first analysis result of a certain object. For example, the analysis target information is: identification information of the terminal, identification information of the group to which the terminal belongs, any terminal, and so on.

For example, analytical ID = service MOS, analytical filter = application ID, target = UE ID, then the first request is the service MOS analysis result for requesting the terminal's application.

In a possible implementation manner, the first request may also carry first indication information, where the first indication information is used to indicate that the terminal is a roaming terminal. In other words, the first indication information is used to indicate that what the first request requests is the analysis result corresponding to the roaming terminal.

In a possible implementation manner, the first request may also carry the home location identification information of the terminal. The home location identification information of the terminal may be one or more of the following identification information: the H-PLMN ID of the terminal, the area information of the home location where the terminal is located (for example, belonging to Shanghai Mobile), and the identification information of the H-NWDAF. Among them, the identification information of H-NWDAF is used to uniquely identify the NWDAF corresponding to the terminal’s home location, for example, H-NWDAF ID or H-NWDAF corresponding service area (H-NWDAF serving PLMN ID, H-NWDAF serving TA list, H -NWDAF serving geographic area (such as Shanghai).

Based on the foregoing implementation manner, before sending the first request, the V-NF/V-AF/V-OAM may also need to obtain the home location identification information of the terminal. The foregoing V-NF/V-AF/V-OAM can obtain the terminal's home location identification information in the following two ways:

Manner 1: When the terminal's subscription data includes the terminal's home location identification information, the V-NF/V-AF/V-OAM can obtain the terminal's home location identification information through the terminal's subscription data. Specifically, when V-NF/V-AF/V-OAM is V-AMF, V-AMF can obtain the terminal's subscription data from H-UDM/H-UDR in the registration process initiated by the terminal, and obtain the subscription data from the terminal Obtain the attribution identification information of the terminal in When V-NF/V-AF/V-OAM is V-SMF, V-SMF can obtain UE’s subscription data from H-UDM/H-UDR during the PDU session establishment or modification process initiated by the terminal, and obtain the subscription data from the subscription Obtain the terminal’s home location identification information from the data; when V-NF/V-AF/V-OAM are other network elements in the V-PLMN (V-PCF, V-UPF, etc.), you can start with V-AMF or The V-SMF obtains the subscription data of the terminal, and then obtains the home location identification information of the terminal from the subscription data.

Manner 2: The V-NF/V-AF/V-OAM queries the network repository function (NRF) NRF to obtain the home location identification information of the terminal. Specifically, for example, the query message carries the terminal's H-PLMN ID and the area information of the terminal's home location (for example, the UE belongs to the Shanghai area of China Mobile), then the query message is used to query the NRF for the H-PLMN ID or the terminal home location The area corresponding to H-NWDAF. In this way, each NWDAF is required to register with the NRF in advance, and the PLMN or service area information corresponding to the NWDAF is registered in the NRF.

205. V-NWDAF sends a second request to H-NWDAF.

The second request is used to request the second analysis result corresponding to the terminal stored in the H-NWDAF.

Before sending the second request, the V-NWDAF needs to obtain the identification information of the H-NWDAF in order to address the H-NWDAF. Specifically, V-NWDAF can obtain H-NWDAF identification information in the following ways:

Manner A: When the V-NF/V-AF/V-OAM directly provides the identification information of the H-NWDAF in the first request, the V-NWDAF obtains the identification information of the H-NWDAF according to the first request.

Method B: V-NWDAF maps out the identification information of H-NWDAF according to the H-PLMN ID of the terminal and/or the area information of the home area where the terminal is located. This method requires that the mapping relationship between each PLMN ID and/or each home area information and the corresponding NWDAF be stored in the V-NWDAF.

Method C: Similar to the second method in step 204, V-NWDAF queries NRF to obtain the H-NWDAF identification information of the terminal, where the query message carries the identification information of the terminal, the HPLMN ID of the terminal, and the area information of the home location of the terminal .

Method D: V-NWDAF queries the home H-UDM/H-UDR to obtain the H-NWDAF identification information of the terminal, where the query message carries the identification information of the terminal, the HPLMN ID of the terminal, and the area information of the home location of the terminal.

Specifically, the second request includes an analysis result type identifier (such as analytic ID) or an event identifier (such as event ID), which is used to indicate the type of the second analysis result specifically requested. The analytic/event ID carried in the second request is the same as the analytic/event ID in the first request, or the analytic/event ID carried in the second request is generated based on the analytic/event ID in the first request.

In a possible implementation, the second request may also include analysis results or event filter conditions (such as analytic/event filter), which are used to indicate that the specific request is the second analysis result that meets the filter conditions, which can be It is generated according to the filter condition carried in the first request. For example, the filter conditions are: time filter conditions, area filter conditions, slice filter conditions, DNN filter conditions, etc.

In a possible implementation manner, the second request may also include analysis object information, which is used to indicate that the specific request is the second analysis result of a certain object. For example, the analysis target information is: identification information of the terminal, identification information of the group to which the terminal belongs, any terminal, and so on. The analysis target information contained in the second request may be generated based on the analysis target information contained in the first request. For example, the analysis target information carried in the first request is the identification information of a single terminal, and the analysis target information carried in the second request may be the identification information of the single terminal or the identification of the terminal group where the single terminal is located. information.

In a possible implementation manner, the second request may also carry roaming indication information, and the roaming indication information is used to indicate that the data analysis result for the roaming terminal in the H-PLMN needs to be obtained.

In a possible implementation manner, the second request may also carry visited place identification information of the visited place where the terminal is located. The visited place identification information is used to describe the identity of the sender of the second request, in other words, used to inform the processing object of the second request of the request subject of the second data analysis result. Wherein, the visited place identification information of the visited place where the terminal is located may be one of the following types of information: V-PLMN ID of the visited place where the terminal is located, identification information of the V-NWDAF of the visited place where the terminal is located, and area information of the visited place where the terminal is located. Among them, the identification information of V-NWDAF is used to uniquely identify the NWDAF that provides data analysis services for the terminal in the visited place. For example, the identification information of V-NWDAF is V-NWDAF ID or the service area corresponding to V-NWDAF (V-NWDAF serving PLMN ID, V-NWDAF serving TA list, V-NWDAF serving geographic area (such as Beijing)) information. The area information of the visited place where the terminal is located is used to indicate the specific area where the terminal is currently located in the visited place network.

206. H-NWDAF sends a second response to V-NWDAF.

The second response is used to feed back the corresponding second analysis result of the terminal stored in the H-NWDAF to the V-NWDAF.

The second analysis result fed back by H-NWDAF in the embodiment of this application may be one or more of the following data analysis result 1, data analysis result 2, and data analysis result 3:

Data analysis result 1: H-NWDAF analysis result generated in H-PLMN for the terminal or the roaming terminal group to which the terminal belongs.

Specifically, before roaming to the V-PLMN, the terminal or the roaming terminal group to which the terminal belongs has performed a mobility process or a session process in the H-PLMN. In these processes, the H-NF and H-AF of the H-PLMN , H-OAM, etc. generate corresponding record data (or called raw data). H-NWDAF collects different raw data sets according to different analytic IDs, and performs data analysis on these raw data sets to obtain the corresponding analytic ID Related analysis results, that is, data classification result 1. The data analysis result 1 is stored in H-NWDAF or H-UDR/H-UDM, and can be sent to V-NWDAF as the second analysis result when requested by V-NWDAF.

Obtain the data analysis result 1 for the specific analytic ID and optional information (such as filter conditions, analysis object information, etc.) in the second request, and feed back the data analysis result 1 to V-NWDAF. In a possible implementation manner, the data analysis result may be identified by the home location identification information of the terminal, and the home location identification information of the terminal is used to indicate that the analysis result is a corresponding analysis result generated in the H-PLMN. For example, for a certain terminal, H-NWDAF analyzes its business behavior characteristics based on its corresponding original data set in H-PLMN, and H-NWDAF feeds back the terminal’s business behavior characteristics in H-PLMN to V -NWDAF. Of course, in a possible implementation manner, if the V-NWDAF defines that only the service behavior characteristics of the UE on Monday need to be obtained, then the H-NWDAF only needs to feed back the service behavior characteristics of the terminal in the H-PLMN on Monday. For another example, for a roaming terminal group where a certain terminal is located, H-NWDAF analyzes the group’s common business behavior characteristics based on the original data set corresponding to the group’s previous H-PLMN, and H-NWDAF takes the common characteristics The business behavior characteristics are fed back to V-NWDAF. Of course, in a possible implementation, if V-NWDAF restricts that it only needs to obtain the business behavior characteristics of the group in a certain area, then H-NWDAF only needs to feed back the common business behavior of the group in the area. feature.

Data analysis result 2: H-NWDAF saved analysis results of the terminal or the roaming terminal group to which the terminal belongs in the V-PLMN.

Specifically, the terminal has roamed to the V-PLMN before, and the terminal or the roaming terminal group to which the terminal belongs has performed the mobility process or the session process in the V-PLMN. In these processes, the V-NF and V of the V-PLMN -AF, V-OAM, etc. generate corresponding recorded data (or called raw data). V-NWDAF collects different raw data sets according to different analytic IDs, and performs data analysis on these raw data sets to obtain the Analytic ID-related analysis results, that is, data classification results 2. The data analysis result 2 is stored in H-NWDAF or H-UDR/H-UDM, and can be sent to V-NWDAF as a second analysis result when requested by V-NWDAF.

H-NWDAF obtains the data analysis result 2 for the specific analytic ID and optional information (such as filter conditions, analysis object information, etc.) in the second request, and feeds back the data analysis result 2 to V-NWDAF. In a possible implementation manner, the data analysis result may be identified by the visitor location identification information of the terminal, and the visitor location identification information of the terminal is used to indicate that the analysis result is a corresponding analysis result generated in the V-PLMN. For example, for a certain terminal, V-NWDAF analyzes its business behavior characteristics based on the corresponding original data set in the V-PLMN. Of course, in a possible implementation manner, if the V-NWDAF restricts that only the business behavior characteristics of the terminal need to be acquired on Monday, the H-NWDAF only needs to feed back the business behavior characteristics of the terminal in the V-PLMN on Monday. For another example, for a roaming terminal group where a certain terminal is located, V-NWDAF analyzes the common business behavior characteristics of the group based on the original data set corresponding to the group in the V-PLMN. H-NWDAF Common business behavior characteristics are fed back to V-NWDAF. Of course, in a possible implementation, if V-NWDAF restricts that only the business behavior characteristics of the group within a certain area need to be acquired, then H-NWDAF only needs to feed back the terminal’s information in the corresponding area of the V-PLMN. Common business behavior characteristics of the group.

Data analysis result 3: H-NWDAF has saved analysis results of the terminal or the roaming terminal group to which the terminal belongs in other V-PLMNs.

Other V-PLMNs are relative to the V-PLMN in the examples of this application. If the H-PLMN described in the examples of this application is a PLMN in China, the V-PLMN is a PLMN in the United States, and other V-PLMNs can be A PLMN in France, or other non-US PLMN and non-Chinese PLMN. Other V-PLMNs are labeled with V’-PLMN.

Specifically, the terminal has roamed to the V'-PLMN before, and the terminal or the roaming terminal group to which the terminal belongs has performed mobility procedures or conversation procedures in other V-PLMNs. In these procedures, the V'of the V'-PLMN -NF, V'-AF, V'-OAM, etc. have produced corresponding recorded data (or called raw data). V'-NWDAF collects different raw data sets according to different analytic IDs, and performs processing on these raw data sets. Data analysis to obtain the analysis result related to the analytic ID, that is, the data classification result 3. The data analysis result 3 is stored in H-NWDAF or H-UDR/H-UDM, and can be sent to V-NWDAF as the second analysis result when requested by V-NWDAF.

H-NWDAF obtains the data analysis result 3 for the specific analytic ID and optional information (such as filter conditions, analysis object information, etc.) in the second request, and feeds the data analysis result 3 back to V-NWDAF. In a possible implementation manner, the data analysis result may be identified by the visitor identification information of the terminal, and the visitor identification information of the terminal is used to indicate that the analysis result is a corresponding analysis result generated in the V'-PLMN. For example, for a certain terminal, V’-NWDAF analyzes its business behavior characteristics based on the corresponding original data set in the V’-PLMN. Of course, in a possible implementation manner, if V-NWDAF restricts that only the business behavior characteristics of the terminal need to be acquired on Monday, then H-NWDAF only needs to feed back the business behavior characteristics of the terminal in the V’-PLMN on Monday. For another example, for the roaming terminal group where a certain terminal is located, V'-NWDAF analyzes the common business behavior characteristics of the group based on the original data set corresponding to the group in V'-PLMN, H-NWDAF Feedback the common business behavior characteristics to V-NWDAF. Of course, in a possible implementation manner, if V-NWDAF limits the need to obtain only the business behavior characteristics of the group within a certain area, then H-NWDAF only needs to report that the terminal is in the corresponding area of the V'-PLMN. The common business behavior characteristics of the group within.

207. The V-NWDAF collects the first data generated by the terminal in the V-PLMN.

The first data refers to the relevant analytic ID and object (such as the terminal) contained in the first request for V-NWDAF, and according to optional filter conditions, from V-NF, V-AF, UE, V-OAM The various related raw data collected by V-NWDAF is used for data analysis to generate the required analysis results. Among them, the process of V-NWDAF collecting the first data of the visited place is similar to the process of H-NWDAF collecting the original data of the attribution, which will not be repeated here.

208. The V-NWDAF generates the first analysis result of the terminal in the visited V-PLMN according to the first data collected in the V-PLMN and the second analysis result sent from the H-NWDAF.

Of course, this step 208 is only one way of generating the first analysis result, and other ways can be understood by participating in the corresponding description in step 103 of the embodiment corresponding to FIG. 3, and will not be repeated here.

209. V-NWDAF sends a first response to V-NF/V-AF/V-OAM.

The first response is used to feed back the first analysis result to the V-NF/V-AF/V-OAM.

In a possible implementation, the identification information of the visited place can be used in the first response, such as V-PLMN ID and/or V-NWDAF to indicate that the first analysis result is in VPLMN or V-NWDAF Generated in.

In a possible implementation manner, the identification information of the home location may be used in the first response, such as H-PLMN ID and/or H-NWDAF, to indicate that the first analysis result is for the H-PLMN ID and/or H-NWDAF for roaming terminals.

In a possible implementation manner, the first response may include a combination of the foregoing two identifiers.

In a possible implementation manner, the first response may include first indication information, and the first indication information is used to indicate that the first analysis result is generated for a roaming terminal.

210. The V-NF/V-AF/V-OAM/terminal formulates an enhancement strategy according to the first analysis result.

To explain one point, in the absence of the first analysis result, V-NF/V-AF/V-OAM/terminals already have certain specific functions, for example, PCF has the function of policy formulation, and AMF has the function of mobility management. AF has functions such as application layer message processing, etc., they can formulate corresponding function strategies before executing corresponding function procedures, and V-NF/V-AF/V-OAM/terminals execute corresponding function procedures according to corresponding function strategies. In the method described in the embodiment of this application, if the analysis result corresponding to the roaming terminal can be obtained from the data analysis network element, the V-NF/V-AF/V-OAM/terminal can formulate corresponding enhancement strategies based on the analysis result. The enhanced strategy can assist V-NF/V-AF/V-OAM/terminals to better perform corresponding functional processes, such as improving the accuracy of functions and shortening the delay of the process, thereby improving the user experience of roaming terminals.

In a possible implementation manner, the first analysis result is service experience evaluation data of the terminal, and the first functional network element is a policy control function network element, then the policy control function network element is based on the terminal’s The service experience evaluation data formulates a service quality enhancement strategy for the service of the terminal.

In a possible implementation manner, the first analysis result is mobility analysis data of the terminal, and the first functional network element is a mobility management function network element, then the mobility management function network element is based on the The mobility analysis data of the terminal formulates mobility management enhancement strategies for the terminal.

In the above embodiment corresponding to FIG. 4, it is described that the V-NWDAF generates the first analysis result. The following further describes sending the first analysis result back to the H-PLMN for storage in conjunction with the embodiment corresponding to FIG. 5. There are two possible implementations of sending the first analysis result back to the H-PLMN for storage as shown in Figure 5, among which steps 301 to 304 are the first possible implementation, and steps 401 to 406 are the second possible Method to realize. The following are respectively introduced in conjunction with Figure 5.

As shown in FIG. 5, another embodiment of the data processing method provided by the embodiment of the present application may include:

301. H-NWDAF sends a roaming terminal subscription request to V-NWDAF.

The subscription request is used to subscribe to the first analysis result of the terminal roaming from the H-PLMN to the V-PLMN.

H-NWDAF can subscribe to V-NWDAF the relevant data analysis results of the roaming terminal. Here, it can be a subscription for a single terminal or a subscription for a group of roaming terminals. In other words, the subscription object identification information in the subscription request may be the identification information of a single roaming terminal or the identification information of a roaming terminal group.

Among them, in one possible implementation, the reporting conditions in the subscription request can be set to periodic reporting, such as monthly reporting, or event reporting. For example, the reporting event is the roaming access of gold users and the number of roaming users. Reach the set value, etc.

302. V-NWDAF uses the method described in the embodiment corresponding to FIG. 4 to generate a first analysis result related to the terminal.

Specifically, in a possible implementation, when H-NWDAF subscribes to the first analysis result of a single roaming terminal, V-NWDAF uses the method described in the embodiment corresponding to FIG. 4 to generate the relevant first analysis result of the single roaming terminal. 1. Analysis result;

In another possible implementation, when H-NWDAF subscribes to the first analysis result of the roaming terminal group, then V-NWDAF uses the method described in the embodiment corresponding to FIG. 4 to generate the correlation of the roaming terminal group. The first analysis result;

303. Determine whether the reporting condition is met, if the reporting condition is met, step 304 is executed, and if the reporting condition is not met, step 304 is not executed.

This step 303 is not a necessary step, and it can also be reported directly without judgment.

304. The V-NWDAF sends the first analysis result generated by the roaming terminal in the V-PLMN to the H-NWDAF.

Among them, V-NWDAF reports according to the reporting conditions in the subscription message. For example, it may be a report by a single terminal, or a report by a group of roaming terminals.

In a possible implementation manner, the first analysis result can be identified by the identification information of the visited place, for example, VPLMN ID and/or V-NWDAF to indicate that the first analysis result is in the VPLMN or V-NWDAF Generated.

In a possible implementation manner, the first analysis result can also be identified by the identification information of the attribution, such as H-PLMN ID and/or H-NWDAF to indicate that the first analysis result is for the H-PLMN ID and/or H-NWDAF. -PLMN ID and/or H-NWDAF for roaming terminals.

In a possible implementation manner, the first analysis result can be identified by a combination of the above two.

Steps 301 to 303 describe the scheme of triggering the subscription request by H-NWDAF. The following describes the scheme of triggering the subscription request by H-UDM/H-UDR in conjunction with steps 401 to 406 in FIG. 5.

401. The H-UDM/H-UDR sends a first subscription request of the roaming terminal to the V-UDM/V-UDR.

The first subscription request is used to subscribe to the first analysis result of the terminal roaming from the H-PLMN to the V-PLMN.

H-UDM/H-UDR can subscribe to V-UDM/V-UDR to roam into the terminal related data analysis results. Here, it can be a subscription for a single terminal or a subscription for a group of roaming terminals. In other words, the subscription object identification information in the subscription request may be the identification information of a single roaming terminal or the identification information of a roaming terminal group.

The setting of the reporting condition in the first subscription request can be understood with reference to the description in step 301.

402. The V-UDM/V-UDR sends a second subscription request to V-NWDAF.

The function of the second subscription request can participate in the first subscription request for understanding.

The setting of the reporting condition in the second subscription request can be understood with reference to the description in step 301.

403. V-NWDAF uses the method described in the embodiment corresponding to FIG. 4 to generate a first analysis result related to the terminal.

Specifically, in a possible implementation manner, when the V-UDM/V-UDR subscribes to the first analysis result of a single roaming terminal, then V-NWDAF uses the method described in the embodiment corresponding to FIG. 4 to generate the single roaming The relevant first analysis result of the terminal;

In another possible implementation, when the V-UDM/V-UDR subscribes to the first analysis result of the roaming terminal group, then V-NWDAF generates the roaming terminal using the method described in the embodiment corresponding to FIG. 4 The relevant first analysis result of the group;

404. V-NWDAF sends the first analysis result to V-UDM/V-UDR.

Of course, if the report condition is included in the second subscription request, the V-NWDAF can send the first analysis result to the V-UDM/V-UDR according to the report condition.

405. The V-UDM/V-UDR can determine whether the reporting conditions are met.

This step 405 may be executed or not, and step 406 may be executed directly.

406. The V-UDM/V-UDR sends the first analysis result to the H-UDM/H-UDR.

Among them, V-UDM/V-UDR is reported according to the reporting conditions in the subscription message. For example, it may be a report by a single terminal, or a report by a group of roaming terminals.

In a possible implementation manner, the first analysis result may be identified by the identification information of the attribution, such as VPLMN ID and/or V-NWDAF, to indicate that the first analysis result is in the VPLMN or V-NWDAF Generated.

It is described above that the first functional network element requests the first analysis result of the terminal through the first request. In fact, when the first functional network element sends the first request, it may not specify the first analysis result of the requesting terminal. The following describes a data processing solution that does not specify the first analysis result of the requesting terminal in conjunction with FIG. 6.

As shown in FIG. 6, another embodiment of the data processing method provided in the embodiment of the present application may include:

501. The first functional network element sends a first request to the first data analysis network element, and accordingly, the first data analysis network element receives the first request sent by the first functional network element.

The first request is used to request the first analysis result.

For the setting method of the first request in step 501, refer to the setting method of the first request in steps 101 and 204 for details. E.g:

In a possible implementation manner, the first request may include type identification information of the first analysis result, and the type identification information is used to identify the type of the first analysis result; in this way, the first data analysis network element Then, the first analysis result corresponding to the type identification information of the roaming terminal group can be generated according to the first request. The type identification information can be understood by participating in the data analysis result 1, the data analysis result 2, and the data analysis result 3 in the embodiment corresponding to FIG. 4 above.

In a possible implementation manner, the first request may also include an analysis result or an event filter condition, which is used to indicate that the specific request is the first analysis result that meets the filter condition. For example, the filter conditions are: time filter conditions, area filter conditions, business type filter conditions, slice filter conditions, DNN filter conditions, etc.

In a possible implementation manner, the first request may include second indication information or/and the attribution identification information, and the second indication information is used to indicate that the first request is used to request a group of roaming terminals The first analysis result, the home location identification information is used to indicate that the first request is used to request the first analysis result of the roaming terminal group at the home location corresponding to the home location identification information.

The only difference is that the first request in step 501 does not specify specific analysis object information. For example, in a possible implementation, the first request may not carry a specific terminal identifier or group identifier, that is, the analysis object. The content of the message is empty. In another possible implementation manner, the analysis object information carried in the first request may be any terminal. The first request in steps 101 and 204 will carry the terminal identifier or the group identifier or other information that can specify the analysis object.

For example, if analytic ID=service MOS, analytic filter=application ID, target=NA/any, then UE, then the first request is the service MOS analysis result for requesting application, and the analysis result is applicable to all terminals.

502. The first data analysis network element generates the first analysis result for the roaming terminal group.

When the first request does not carry a specific terminal identifier or a specific terminal group identifier, that is, when the first request does not precisely limit the analysis object, the data analysis network element can also distinguish the analysis object, that is, separate the roaming terminal group The relevant data is collected and analyzed, and the first analysis result applicable to the roaming terminal group is obtained, thereby ensuring that the subsequent first functional network element learns that the first analysis result is specifically applicable to the roaming terminal.

The method for generating the first analysis result may be: first generate a third analysis result for each terminal in the group. For example, if there are N roaming terminals in the group, there are N third analysis results. Then, the first analysis result is generated according to the N third analysis results. The third analysis result refers to the data analysis result generated by the first data analysis network element of the visited place for the single roaming terminal in the visited place. The first analysis result may be a common feature extracted from the N third analysis results.

In a possible implementation manner, before this step 502, the first data analysis network element may determine the roaming terminal group. In a possible implementation manner, the first request includes second indication information or/and the attribution identification information, and the second indication information is used to indicate that the first request is used to request a group of roaming terminals The first analysis result, the home location identification information is used to indicate that the first request is used to request the first analysis result of the roaming terminal group at the home location corresponding to the home location identification information. The first data analysis network element determines the roaming terminal group according to the second indication information or/and the home location identification information.

In another possible implementation manner, the first data analysis network element may obtain the terminal's home location identifier by correlating the original data generated by the terminal in the visited place, and determine it based on the difference between the terminal's home location identifier and the visited place where it is located. The terminal is a roaming terminal, and multiple roaming terminals can be classified as a roaming terminal group. Further, the first data analysis network element may classify terminals with the same home identity as the same roaming terminal group.

A possible implementation may be: Step 5011 is performed before step 502: the first data analysis network element receives the first data of the roaming terminal group from the second function network element, and the second function The network element belongs to the visited place where the roaming terminal group is located; accordingly, step 502 is: the first data analysis network element generates the first analysis result according to the first data.

The second functional network element may be an NF network element, an AF network element, an OAM network element, or a terminal belonging to the visited place described above. The first data refers to the process/result data generated in itself, the visited network, the business server in the visited place, etc. when the terminal executes the mobility process or the conversation process in the visited network. A possible implementation manner may be: Step 5012 is performed before step 502: the first data analysis network element receives the second data from the terminal of a third functional network element, and the third functional network element belongs to The home location of the terminal;

Correspondingly, step 502 is: the first data analysis network element generates the first analysis result according to the second data.

The third functional network element may be the NF network element, AF network element, OAM network element, etc. belonging to the home area described above. The second data refers to the process/result data generated in the home network, home service server, etc. when the terminal executes the mobility process or the session process in the visited network.

A possible implementation manner may be: step 5013 is performed before step 502: the first data analysis network element receives the second analysis result from the terminal of the second data analysis network element or the first data storage network element , The second data analysis network element or the first data storage network element belongs to the attribution of the terminal.

Correspondingly, step 502 is: the first data analysis network element generates the first analysis result according to the second analysis result.

In a possible implementation manner, the second analysis result is an analysis result generated by the second data analysis network element at the attribution, and the analysis result type corresponding to the second analysis result is the same as the first analysis result The corresponding analysis result types are the same. For example, the first analysis result refers to the service MOS analysis result of the application 1 by the visitor V-NWDAF, and the second analysis result refers to the service MOS analysis result of the application 1 by the home H-NWDAF.

In a possible implementation manner, the second analysis result is an analysis result generated by the second data analysis network element for the roaming terminal group at the home location. For example, the second analysis result refers to the service MOS analysis result generated by the home H-NWDAF on the application 1 of the roaming terminal group, where the second data analysis network element can determine which one to obtain according to the instruction of the first data analysis network element The second analysis result of the home area of the roaming terminal group.

In a possible implementation manner, the second analysis result is an analysis result generated by the first data analysis network element on the roaming terminal group in the visited place. To illustrate one point, the second analysis result is the analysis result that the first data analysis network element once generated on the roaming terminal group in the corresponding visited place and sent the analysis result stored in the home location of the roaming terminal group.

In a possible implementation manner, the second analysis result is an analysis result generated by the fourth data analysis network element on the roaming terminal group at the visited place corresponding to the fourth data analysis network element, wherein the fourth data analysis network element The visited place corresponding to the data analysis network element is different from the visited place corresponding to the first data analysis network element or the second data analysis network element. To illustrate one point, the second analysis result is the analysis result that the fourth data analysis network element once generated on the roaming terminal group in the corresponding visited place and sent the analysis result stored in the home area of the roaming terminal group.

Wherein, the method of obtaining the second analysis result may be:

The first data analysis network element determines the second data analysis network element or the first data storage network element according to the home location identification information of the roaming terminal group.

In a possible implementation manner, the second request includes visited place identification information of the visited place where the roaming terminal group is located. The identification information of the visited place may indicate the source of the second request.

In a possible implementation manner, the second request further includes type identification information of the second analysis result, and the type identification information is used to identify the type of the second analysis result; the second data analysis network element or The first data storage network element determines the second analysis result corresponding to the type identification information according to the second request. Optionally, the second request further includes identification information of the roaming terminal group, which is used to indicate the request for the second analysis result of the roaming terminal group.

The second request also includes visited place identification information of the visited place. The visited place identification information is used to describe the identity of the sender of the second request, in other words, used to inform the processing object of the second request of the request subject of the second data analysis result.

The visited place identification information includes one or more of the following information: the public land mobile network PLMN identification information (PLMN ID) of the visited place, the identification information (NWDAF ID) of the data analysis network element of the visited place, or the area of the visited place Information, the regional information of the visited place can refer to which area of the visited place, such as Shenzhen in Guangdong Province.

The identification information (NWDAF ID) of the data analysis network element in the visited place is used to uniquely identify the NWDAF that provides data analysis services for the terminal in the visited place.

It is described above that the second analysis result is the analysis result obtained by analyzing the data of the home place. In fact, the second analysis result can also be the analysis result of the place visited by the roaming terminal group. The data analysis result is determined by the roaming terminal group. The data analysis network element of the place visited by the terminal group is generated and sent to the home place for storage. For example, the home of the roaming terminal group is the Shanghai area, and the roaming terminal group currently roams to the Beijing area. Before that, the roaming terminal group also roamed to the Guangdong area, so the second analysis result may also be the Guangdong area Analyze the results. It should be noted that the place visited by the terminal in the past may be the same as or different from the place visited currently. Take for example that the place visited before can be different from the place visited currently:

The foregoing process of obtaining the second analysis result has been described. The second analysis result may be included in the second response, and the second response may also include the identification information of the attribution of the roaming terminal group. The home location identification information is used to indicate that the second analysis result comes from the home location.

In the second response, the second data analysis network element or the first data storage network element sends the analysis result of the visited place or the analysis result of the home place, which can be implemented in multiple ways. For example, in a possible implementation, if there is an analysis result of the place visited, the analysis result of the place visited will be sent first; if there is no further analysis result of the home place; if there are neither, then send An empty message may indicate that there is no secondary analysis result. For another example, in another possible implementation, when there is both the analysis result of the visited place and the analysis result of the attribution, both can be sent at the same time. For another example, in another possible implementation manner, it is also possible to distinguish in detail whether the visited place once is the current visited place of the roaming terminal group, and the following analysis results are regarded as the second analysis according to the priority from high to low The result is sent: the roaming terminal group’s current visitation place has produced the analysis result of the roaming terminal group, the home place has produced the analysis result of the roaming terminal group, and other visited places have produced the analysis result of the roaming terminal group. , Empty message or indicate that there is no secondary analysis result. Of course, there are other specific implementation manners, which will not be listed here.

503. The first data analysis network element sends a first response to the first functional network element, and accordingly, the first functional network element receives the first response.

The first response includes the first analysis result, the first response also includes first indication information or home location identification information, and the first indication information is used to indicate that the first data analysis result is for roaming Generated by a terminal group, and the home location identification information is used to indicate that the first data analysis result is generated for a roaming terminal group at the home location.
