As can be known to those skilled in the art, with the development of technology and the emergence of new scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The terms "first," "second," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the application provides a data processing method and device, and a data analysis network element can analyze data of a roaming terminal. The following are detailed below.

In the data processing system, as shown in fig. 1, the data analysis network element may collect and analyze data generated by the functional network element for the terminal, and after obtaining an analysis result, the analysis result may be returned to the functional network element. In this embodiment of the application, the data analysis network element may be a network data analysis function (NWDAF) network element or a Management Data Analysis Service (MDAS) network element. The functional network elements may include Network Function (NF) network elements, Application Function (AF) network elements, Operation Administration and Maintenance (OAM) network elements or terminals, and the like.

The NF network element refers to a module or an entity that performs some or some specific functions in an operator network, and may include an access and mobility management function (AMF) network element, a Radio Access Network (RAN) network element, a Session Management Function (SMF) network element, a User Plane Function (UPF) network element, a Policy Control (PCF) network element, and the like.

The operation management and maintenance network element refers to a network element including at least one of the following functions: a network resource deployment function, a network operation management or maintenance function.

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

A terminal (also referred to as User Equipment (UE)) is a device with wireless transceiving function, and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.

Data analysis network elements, for example: the NWDAF or MDAS may collect data from the AF network element, NF network element, OAM network element or terminal, or may store the collected data in a data warehouse, and when analysis is needed, obtain corresponding data from the data warehouse for analysis, and after the data analysis network element obtains an analysis result, the data analysis network element may send the analysis result to the AF network element, NF network element, OAM network element or terminal, so that the AF network element, NF network element, OAM network element or terminal may execute a corresponding policy according to the corresponding analysis result, for example: enhancement of UPF selection, enhancement of Quality of Service (QoS) parameter generation, and the like.

What kind of enhancement operation is performed by the AF network element, the NF network element, the OAM or the terminal is to improve the service quality of the terminal, and the data processing method provided in the embodiment of the present application is directed to a roaming terminal. Roaming here refers to a broad roaming concept, including the following two layers: an aspect refers to a terminal moving from one Public Land Mobile Network (PLMN) to another PLMN, such as: roaming from a China Mobile network to an American AT & T network; another aspect refers to a terminal moving from one area to another area in the same PLMN, such as from one NWDAF service area to another NWDAF service area, or such as: roaming from the Beijing area of China Mobile to the Shanghai area of China Mobile. In any of the above roaming meanings, a destination network or a destination area to which the terminal moves may be referred to as a visited place, and a network or an area of origin from which the terminal originates may be referred to as a home. Generally, a PLMN has many data analysis network elements, and for example, the data analysis network element is an NWDAF, as shown in fig. 2A and 2B, these NWDAFs may be deployed according to national, provincial and urban architectures, and a terminal may roam among different NWDAFs. During terminal roaming, the NWDAF performing 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, the NWDAF performing data processing on the roaming terminal is a PLMN-level NWDAF. For example: FIG. 2B shows: if the roaming terminal roams from one province of the same PLMN to another province, the NWDAF performing data processing on the roaming terminal is an NWDAF belonging to the province hierarchy. If the roaming terminal roams from a city of a province to another city of the province, such as from Guandong Shenzhen city to Heyuan city, the NWDAF performing 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 visited place of the terminal may be referred to as a visited NWDAF, or may be referred to as a first data analysis network element. The NWDAF of the home of the terminal may be referred to as home-NWDAF, or may be referred to as a second data analysis network element. In general, the NWDAF performs data processing based on the request of the above listed functional network elements, so the functional network element belonging to the visited place may be referred to as a visited functional network element, or may be referred to as a first functional network element. Accordingly, the functional network element of the home location of the roaming terminal may be referred to as a home functional network element, or may be referred to as a second functional network element.

The following describes a data processing method provided in an embodiment of the present application with reference to fig. 3.

As shown in fig. 3, an embodiment of a method for data processing provided in 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 accordingly, the first data analysis network element receives the first request sent by the first functional network element.

The first request is used for requesting a first analysis result of the terminal. The first request is triggered by the first functional network element based on the terminal roaming under network coverage of the first functional network element, e.g., when the first functional network element is an AMF, then the first functional network element may trigger the first request upon receiving a registration request sent by the roaming 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 a session establishment request sent by the roaming terminal.

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

The terminals here comprise individual terminals or groups of terminals.

The first analysis result may be an analysis result for one 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 an analysis result of the roaming terminal group to which the terminal belongs, the first analysis result may be generated in a manner that: first, a third analysis result is generated for each terminal in the group, for example: if there are N roaming terminals in the group, there are N third analysis results. And then generating a first analysis result according to the N third analysis results. And the third analysis result refers to a data analysis result generated by the first data analysis network element of the visited place to the single roaming terminal at the visited place. The first analysis result may be a feature of commonality extracted from the N third analysis results.

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

After receiving the first request, the first data analysis network element determines whether the terminal is a roaming terminal, and if so, performs subsequent operations.

There are various ways for the first data analysis network element to determine whether the terminal is a roaming terminal, for example:

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

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

In a possible implementation manner, the first request may include an identifier of the terminal, and the first data analysis network element may determine, through the identifier of the terminal, a home location to which the terminal is subscribed in the network, and if the home location is not the home location of the first data analysis network element, it may determine that the terminal is a roaming terminal. Specifically, the first data analysis network element may obtain data reported by other functional network elements in the network, obtain a terminal home location identifier associated with the terminal identifier from the data, and determine that the home location of the terminal is not the home location of the first data analysis network element according to the terminal home location identifier. For example, the first request includes a terminal ID, the first data analysis network element may obtain, from the AMF, an HPLMN ID associated with the terminal ID, and the first data analysis network element determines that the terminal is a roaming terminal according to that the HPLMN ID of the terminal is not the same as an ID of a PLMN where the first data analysis network element is located. Of course, it may also be determined that the terminal is a roaming terminal in other ways, which is not limited in this embodiment of the application.

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

In this embodiment of the present application, there may be multiple ways for the first data analysis network element to generate the first analysis result of the terminal, such as:

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

The second functional network element may be the NF network element, the AF network element, the OAM network element or the terminal belonging to the visited place, which is described above. The first data refers to process/result data generated in the terminal, the visited network, the visited business server and the like when the terminal executes a mobility flow or a session flow in the visited network. The first data may be data related to a service, or may be other types of data, where the type of the first data is related to the first analysis result, the analysis result may be multiple, and the content of the first data may be different according to different analysis results.

For example, when the first analysis result is a business experience analysis result of an application (e.g., a service MOS of application), the first data is the data types listed in tables 1 and 2 below.

TABLE 1 traffic data collected by NWADF from visited AF

Table 2: network data collected by NWDAF from NF or OAM network element of visited place

One possible implementation may be: step 1022 is performed before step 103: the first data analysis network element receives second data of the terminal from a third functional network element, wherein the third functional network element belongs to the attribution place of the terminal;

accordingly, step 103 is: and 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, the AF network element, the OAM network element, etc. belonging to the home location described above. The second data refers to process/result data generated in the home network, the home service server, and the like when the terminal executes the mobility procedure or the session procedure in the visited network. The second data may be data related to a service, or may be other types of data, where the type of the second data is related to the first analysis result, the analysis results may be various, and the content of the second data included in different analysis results may also be different, and the explanation of the second data is specifically referred to the explanation of the first data.

One possible implementation may be: step 1023 is performed before step 103: the first data analysis network element receives a second analysis result of the terminal from a second data analysis network element or a first data storage network element, and the second data analysis network element or the first data storage network element belongs to a home of the terminal.

Accordingly, step 103 is: and 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 may be generated by combining the first data, the second data, and the second analysis result. Such as:

and generating a first analysis result according to the first data and the second data.

And generating a first analysis result according to the first data and the second analysis result.

And generating a first analysis result according to the second data and the second analysis result.

And generating a first analysis result according to the first data, the second data and the second analysis result.

Of course, the manner of acquiring the first data, the second data, and the second analysis result is the same as that described in the above one possible implementation manner, and details are not 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 at the home location for the terminal or the roaming terminal group to which the terminal belongs. In other words, the second analysis result is an analysis result generated by the second data analysis network element analyzing the relevant data generated by each functional network element in the terminal home location with respect to 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 a service MOS analysis result of the NWDAF at the visited location for application1 of a certain terminal, and the second analysis result refers to a service MOS analysis result of the NWDAF at the home location for application1 of the certain terminal.

In a possible implementation manner, the second analysis result is an analysis result generated by the first data analysis network element at the visited place for the terminal or the roaming terminal group to which the terminal belongs. It is noted that the second analysis result is an analysis result that the first data analysis network element generated at the visited place for the terminal or the roaming terminal group to which the terminal belongs and transmitted and stored in the home place of the roaming terminal group.

The second analysis result is an analysis result generated by a fourth data analysis network element on a corresponding visited place of the terminal or the roaming terminal group to which the terminal belongs in the fourth data analysis network element, wherein the visited place corresponding to the fourth 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. It is noted that the second analysis result is an analysis result that the fourth data analysis network element generated at the visited place for the terminal or the roaming terminal group to which the terminal belongs and transmitted and stored in the home place of the roaming terminal group.

The fourth data analysis network element is only used for expressing the data analysis network element of the visited place where the terminal or the roaming terminal group to which the terminal belongs visited once, and actually, the fourth data analysis network element, the fifth data analysis network element and the like can also be used for expressing that the number of the fourth data analysis network element has no special meaning.

The obtaining mode of the second analysis result may be:

and 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.

The first data analysis network element sends a second request to the second data analysis network element or the first data storage network element, where the second request is used to request the second analysis result;

and 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, wherein the second response comprises the second analysis result.

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

The visitor identification information includes one or more of the following: public Land Mobile Network (PLMN) identification information of the visited place, identification information of a data analysis network element of the visited place, and area information of the visited place, wherein the area information of the visited place can refer to which area of the visited place is, such as Shenzhen city in Guangdong province. For example, in a possible implementation manner, when the terminal roams from one PLMN to another PLMN, the visited identification information of the terminal includes PLMN identification information of the visited place, and optionally further includes identification information of a visited place data analysis network element or area information of the visited place. In another possible implementation manner, when the terminal roams from one area to another area in the same PLMN, the visited identification information of the terminal includes identification information of the visited data analysis network element or area information of the visited place, and it may or may not include the visited PLMN identification information, which is not limited.

The identification information of the data analysis network element of the visited place is used for uniquely identifying the data analysis network element providing the data analysis service for the terminal in the visited place,

the data type of the first data and the second data is related to the required first analysis result, such as the analysis result related to the service of the terminal is requested, and the first data and the second data are the data related to the service directly or indirectly in the related functional network element; if the request is the analysis result related to the abnormal behavior of the terminal, the first data and the second data are the data which are directly or indirectly related to the abnormal behavior of the user in the related functional network element; if other types of analysis results are requested, the first data and the second data are the corresponding types of data.

In fact, the second analysis result may also be an analysis result of the visited place to which the terminal has been brought, and the data analysis result is generated by the data analysis network element of the visited place to which the terminal has been brought and sent to the home place for storage. Such as: the attribution of the terminal is Shanghai area, the terminal roams to Beijing area at present, and the terminal also roams to Guangdong area before the current area, so that the second analysis result can be the analysis result of the Guangdong area. It should be noted that the visited place where the terminal has visited may be the same as or different from the visited place currently visited. Take the example that the visited place can be different from the current visited place:

the second analysis result is an analysis result generated by a fourth data analysis network element on a corresponding visited place of the terminal or the roaming terminal group to which the terminal belongs in the fourth data analysis network element, wherein the visited place corresponding to the fourth 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. And 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 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 generated by the visited place corresponding to the fourth data analysis network element for the terminal.

The above-mentioned 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 further include the attribution identification information of the terminal. The home identification information is used to indicate that the second analysis result is from a home.

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 in the second response, and the implementation method is specifically multiple. For example, in a possible implementation manner, if there is an analysis result of the visited place, the analysis result of the visited place is sent first; if the analysis result of the attribution is not sent again; if neither of them is present, a null message is sent or no second analysis result is indicated. For another example, in another possible implementation, when there are both the analysis result once visited and the analysis result of home, both may be sent simultaneously. For another example, in another possible implementation manner, it may further be further refined to distinguish whether the visited place is the visited place where the terminal is currently located, and send the following analysis results as the second analysis result from high to low in priority: the current visit place of the terminal generates an analysis result for the terminal, the home place generates an analysis result for the terminal, other visit places generate an analysis result for the terminal, and an empty message or indicates that no second analysis result exists. Of course, other specific implementations exist and are not listed here.

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

The first response includes the first analysis result, and the first response further includes first indication information indicating that the first data analysis result is generated for a roaming terminal or home identification information of the terminal indicating that the first data analysis result is generated for a terminal of the home.

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

Optionally, step 105 may also be included after step 104.

105. And 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.

And the second data analysis network element or the first data storage network element belongs to the attribution of the terminal.

106. And the first data analysis network element sends the visiting place identification information of the visiting place where the terminal is located to the second data analysis network element or the first data storage network element.

The visited place identification information is used to indicate that the first analysis result is generated for a terminal roaming to the visited place.

Of course, steps 105 and 106 may be one transmission step or two transmission steps.

Optionally, step 104 may be followed by:

107. and the first functional network element makes an enhancement strategy according to the first analysis result.

In a possible implementation manner, the first analysis result is service experience evaluation data of the terminal, the first functional network element is a policy control functional network element, and the policy control functional network element makes a service quality enhancement policy for the service of the terminal according to the service experience evaluation data of the terminal.

In a possible implementation manner, the first analysis result is mobility analysis data of the terminal, the first functional network element is a mobility management functional network element, and the mobility management functional network element makes a mobility management enhancement policy for the terminal according to the mobility analysis data of the terminal.

In a possible implementation manner, the first analysis result is expected behavior analysis data of the terminal, the first functional network element is a session management functional network element, and the session management functional network element makes a session management enhancement policy for the terminal according to the expected behavior analysis data of the terminal.

Optionally, step 108 may also be included after step 105.

108. And the second data analysis network element or the first data storage network element stores the first analysis result of the terminal.

Optionally, step 109 may also be included after step 105.

109. And the second data analysis network element or the data storage network element receives the visitor location identification information of the visitor location where the terminal is sent by the first data analysis network element.

The foregoing embodiments generally describe the process of data processing after the terminal roams, and the following further describes the method for data processing provided in the embodiments of the present application with reference to fig. 4 and fig. 5.

Since the embodiments of fig. 4 and 5 relate to a plurality of english abbreviations, the english abbreviations are described correspondingly.

Compared with the terminal, the terminal signing place is a home place, and the visited place to which the terminal roams is a visited place.

The PLMN of the attribution is H-PLMN, the NWDAF of the attribution is H-NWDAF, the NF/AF/OAM of the attribution is H-NF/H-AF/H-OAM respectively, and the Unified Data Management (UDM)/User Database (UDR) of the attribution 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, the NF/AF/OAM of the visited place is V-NF/V-AF/V-OAM, and the UDM/UDR of the visited place is V-UDM/V-UDR.

It should be noted that, in the scenarios described in fig. 4 and fig. 5, the network element in the 5G scenario is taken as an example for explanation, and actually, the solution provided in the embodiment of the present application is also applicable to, for example: 4G or future 6G, etc.

It should be noted that, in the scenarios described in fig. 4 and fig. 5 below, the scenario is when the terminal roams between two PLMNs, and in fact, the method is also applicable to scenarios in which the terminal roams between different regions of the same PLMN or between different NWDAFs. The difference is only that the home location and the visited location in the two scenarios have different meanings, wherein the home location generally refers to a home location PLMN and the visited location generally refers to a visited location PLMN; in the latter case home generally refers to a home area and visited generally refers to a visited area. Accordingly, the home identification information and the visited identification information related to the two scenes may be slightly different, specifically, see the description of the home identification information corresponding to the two scenes in step 102, and the description of the visited identification information corresponding to the two scenes in step 103. In addition, fig. 4 and 5 illustrate the data analysis network element as an NWDAF, and actually, 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 method for data processing provided in the embodiment of the present application may include:

201. and 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 the application, the home network of the terminal is an H-PLMN, and the network to which the terminal roams is a V-PLMN.

The terminal initiates a registration process to the V-AMF network element to request to register 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 may determine that the terminal is a roaming terminal through identification information such as an International Mobile Subscriber Identity (IMSI) of the terminal, a subscriber permanent identifier (SUPI), or a globally unique temporary user equipment identifier (GUTI), a Generic Public Subscription Identifier (GPSI), and the like.

In this step 202, the V-AMF may directly determine that the terminal is a roaming terminal according to the identification information of the terminal, for example: and comparing the identification information of the terminal with the identification information of the locally signed terminal, and if the identification information of the terminal is not in the identification information of the locally signed terminal, determining that the terminal is a roaming terminal.

It may also be determined indirectly that the terminal is a roaming terminal according to the identification information of the terminal, for example: the V-AMF may 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 is different from the PLMN ID of the network where the V-AMF is located, determine that the terminal is a roaming terminal.

203. And the V-AMF requests the subscription data of the terminal from the H-UDM/H-UDR.

The subscription data may include H-NWDAF identification information corresponding to the terminal, and may also include H-PLMN ID information and home area information of the terminal, that is, the area to which the terminal specifically belongs in the HPLMN, and the area may have network area identifiers (TAI, TAI list, cell ID list, etc.) or geographic area identifiers (shanghai, beijing, etc.), and the subscription data is sent to the V-AMF by the H-UDR/H-UDM of the H-PLMN.

In addition, the H-NWDAF identification information may have different representations, such as direct identification by H-NWDAF ID or indirect identification by the service area of the H-NWDAF.

204. The V-NF/V-AF/V-OAM in the V-PLMN sends a 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 a proper UPF for a PDU session initiated by the roaming terminal, an SMF in a V-PLMN needs to acquire a service behavior analysis result aiming at the roaming terminal from a V-NWDAF, and then the V-SMF sends a first request to the V-NWDAF for requesting 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, it may be determined that the terminal is a roaming terminal and obtain the subscription data of the terminal through the above steps 201 and 203. In another possible implementation manner, when the other V-NF/V-AF/V-OAM/terminal sends the first request to the V-NWDAF instead of the V-AMF, the other V-NF/V-AF/V-OAM/terminal may obtain the above-mentioned related information of the terminal from the V-AMF.

The first request includes an analysis result type identifier (e.g., analytic ID) or an event identifier (e.g., eventID) that indicates the type of the first analysis result for the particular request. If the analytical ID is: a service mean opinion score (service MOS), an abnormal behavior of a terminal (UE abnormal), a download (load) event of a user plane function network element (UPF), and the like.

In a possible implementation manner, the first request may further include an analysis result or an event filter (e.g., analytic/event filter) for indicating that the specific request is the first analysis result meeting the filter. If the filtration conditions are as follows: temporal filtering criteria, regional filtering criteria, business type filtering criteria, slice filtering criteria, DNN filtering criteria, and the like.

In a possible implementation manner, the first request may further include analysis object information, which is used to indicate that the specific request is a first analysis result of an object. If the analysis object information is: identification information of the terminal, identification information of a group to which the terminal belongs, any terminal, and the like.

For example, if the analytic ID is service MOS, the analytic filter is application ID, and the target is UE ID, the first request is a service MOS analysis result for requesting application of the terminal.

In a possible implementation manner, the first request may further 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 the first request requests the analysis result corresponding to the roaming terminal.

In a possible implementation manner, the first request may further carry home identification information of the terminal. The attribution 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 of the terminal (such as the home location of the Shanghai Mobile), and the identification information of the H-NWDAF. The identification information of the H-NWDAF is used to uniquely identify the NWDAF corresponding to the terminal at the home, for example, the H-NWDAF serving PLMN ID, the H-NWDAF serving TA list, and the H-NWDAF serving geographic area (as described above) corresponding to the H-NWDAF ID or the H-NWDAF.

Based on the above implementation, before sending the first request, the V-NF/V-AF/V-OAM may need to acquire the home identifier of the terminal. The attribution identification information of the V-NF/V-AF/V-OAM acquisition terminal can be obtained in the following two ways:

the first method is as follows: when the subscription data of the terminal contains the attribution identification information of the terminal, the V-NF/V-AF/V-OAM can acquire the attribution identification information of the terminal through the subscription data of the terminal. Specifically, when the V-NF/V-AF/V-OAM is a V-AMF, the V-AMF may obtain subscription data of the terminal from the H-UDM/H-UDR in a registration procedure initiated by the terminal, and obtain home identifier information of the terminal from the subscription data. When the V-NF/V-AF/V-OAM is V-SMF, the V-SMF can acquire subscription data of the UE from H-UDM/H-UDR in a PDU session establishment or modification process initiated by the terminal, and acquire attribution identification information of the terminal from the subscription data; when the V-NF/V-AF/V-OAM is other network elements (V-PCF, V-UPF and the like) in the V-PLMN, the signing data of the terminal can be obtained from the V-AMF or the V-SMF, and then the attribution identification information of the terminal can be obtained from the signing data.

The second method comprises the following steps: the V-NF/V-AF/V-OAM inquires NRF of a network storage function (NRF) to acquire attribution identification information of the terminal. Specifically, for example, the query message carries the H-PLMN ID of the terminal and the area information of the terminal location (e.g., the UE belongs to the china mobile shanghai area), and the query message is used to query the NRF about the H-PLMN ID or the H-NWDAF corresponding to the area of the terminal location. In this way, it is required to register each NWDAF with the NRF in advance, and register PLMN or service area information corresponding to the NWDAF with the NRF.

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

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

The V-NWDAF needs to acquire identification information of the H-NWDAF in order to address the H-NWDAF before sending the second request. Specifically, the V-NWDAF may acquire the identification information of the H-NWDAF in the following ways:

mode A: and when the V-NF/V-AF/V-OAM directly provides the identification information of the H-NWDAF in the first request, the V-NWDAF acquires the identification information of the H-NWDAF according to the first request.

Mode B: and the V-NWDAF maps the identification information of the H-NWDAF according to the H-PLMN ID of the terminal and/or the area information of the home location of the terminal. This requires that the mapping relationship between each PLMN ID and/or each home zone information and the corresponding NWDAF is stored in the V-NWDAF.

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

Mode D: and the V-NWDAF inquires and acquires the H-NWDAF identification information of the terminal from the home H-UDM/H-UDR, wherein the inquiry information carries the identification information of the terminal, the HPLMN ID of the terminal and the area information of the home of the terminal.

Specifically, the second request includes an analysis result type identifier (e.g., analytic ID) or an event identifier (e.g., event ID) that indicates the type of the second analysis result of the specific request. 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 according to the analytic/event ID in the first request.

In a possible implementation manner, the second request may further include an analysis result or an event filter (e.g., analytic/event filter), which is used to indicate that the specific request is the second analysis result that meets the filter, and the second analysis result may be generated according to the filter carried in the first request. If the filtration conditions are as follows: temporal filtering conditions, regional filtering conditions, slice filtering conditions, DNN filtering conditions, and the like.

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

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

In a possible implementation manner, the second request may further carry visited place identification information of a visited place where the terminal is located. The visitor location identification information is used to specify the identity of the second request sender, in other words, to inform the processing object of the second request of the request subject of the second data analysis result. The visiting place identification information of the visiting place where the terminal is located can be one of the following various information: the V-PLMN ID of the visited place where the terminal is located, the identification information of the V-NWDAF of the visited place where the terminal is located, and the area information of the visited place where the terminal is located. The identification information of the V-NWDAF is used to uniquely identify the NWDAF providing data analysis service for the terminal in the visited place, for example, the identification information of the V-NWDAF is a V-NWDAF ID or service area (V-NWDAF serving PLMN ID, V-NWDAF serving TA list, V-NWDAF serving geographic information (e.g., beijing)) information corresponding to the V-NWDAF. The area information of the visited place where the terminal is located is used for indicating the specific area where the terminal is currently located in the visited place network.

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

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

The second analysis result of the H-NWDAF feedback in the embodiment of the present 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: and the H-NWDAF generates an analysis result in the H-PLMN aiming at 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 performs a mobility procedure or a session procedure in the H-PLMN, in which corresponding recorded data (or referred to as original data) is generated by H-NF, H-AF, H-OAM, and the like of the H-PLMN, and the H-NWDAF collects different original data sets according to different analytical IDs, and performs data analysis on the original data sets to obtain an analysis result related to the analytical ID, that is, a data classification result 1. This data analysis result 1 is stored in the H-NWDAF or H-UDR/H-UDM and may be sent to the V-NWDAF as a second analysis result upon a V-NWDAF request.

The data analysis result 1 is obtained for the specific analytical ID and optional information (such as filtering condition, analysis object information, etc.) in the second request, and the data analysis result 1 is fed back to the V-NWDAF. In one possible implementation, the data analysis result may be identified by home identification information of the terminal, which is used to indicate that the analysis result is a corresponding analysis result generated in the H-PLMN. For example, for a certain terminal, the H-NWDAF analyzes its service behavior characteristics according to its corresponding original data set once in the H-PLMN, and the H-NWDAF feeds back the service behavior characteristics of the terminal in the H-PLMN to the V-NWDAF. Of course, in a possible implementation manner, if the V-NWDAF defines that the service behavior feature of the UE only needs to be acquired on monday, the H-NWDAF only needs to feed back the service behavior feature of the terminal on monday in the H-PLMN. For another example, for a roaming terminal group where a certain terminal is located, the H-NWDAF analyzes the common service behavior characteristic of the group according to the original data set corresponding to the group in the H-PLMN, and the H-NWDAF feeds back the common service behavior characteristic to the V-NWDAF. Of course, in a possible implementation manner, if the V-NWDAF defines that the service behavior feature of the group in a certain area only needs to be acquired, the H-NWDAF only needs to feed back the common service behavior feature of the group in the area.

Data analysis result 2: the H-NWDAF stores the analysis result that the terminal or the roaming terminal group to which the terminal belongs generated in the V-PLMN.

Specifically, the terminal roams to the V-PLMN before, the terminal or the roaming terminal group to which the terminal belongs performs a mobility procedure or a session procedure in the V-PLMN, in these procedures, V-NF, V-AF, V-OAM, etc. of the V-PLMN generate corresponding recorded data (or referred to as original data), and the V-NWDAF collects different original data sets according to different analytical IDs, and performs data analysis on these original data sets to obtain an analysis result related to the analytical ID, that is, a data classification result 2. This data analysis result 2 is stored in the H-NWDAF or H-UDR/H-UDM and may be sent to the V-NWDAF as a second analysis result upon a V-NWDAF request.

The H-NWDAF obtains the data analysis result 2 aiming at the specific analytical ID in the second request and optional information (such as filtering conditions, analysis object information and the like), and feeds back the data analysis result 2 to the V-NWDAF. In a possible implementation manner, the data analysis result may be identified by visited place identification information of the terminal, where the visited place 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, the V-NWDAF analyzes its traffic behavior characteristics from its corresponding original data set that was in the V-PLMN. Of course, in a possible implementation manner, if the V-NWDAF defines that the service behavior feature of the terminal only needs to be acquired on monday, the H-NWDAF only needs to feed back the service behavior feature of the terminal on monday in the V-PLMN. For another example, for a roaming terminal group where a certain terminal is located, the V-NWDAF analyzes the common service behavior characteristic of the group according to the original data set of the group once corresponding to the V-PLMN, and the H-NWDAF feeds back the common service behavior characteristic to the V-NWDAF. Of course, in a possible implementation manner, if the V-NWDAF defines that the service behavior characteristics of the group only need to be acquired within a certain area range, the H-NWDAF only needs to feed back the common service behavior characteristics of the group of the terminal within the corresponding area range of the V-PLMN.

Data analysis result 3: and the H-NWDAF stores the analysis result which is generated in other V-PLMNs by the terminal or the roaming terminal group to which the terminal belongs.

Other V-PLMNs are relative to the V-PLMNs in the embodiment of the present application, and if the H-PLMN described in the embodiment of the present application is a certain PLMN in china, the V-PLMN is a certain PLMN in the united states, and the other V-PLMNs may be a certain PLMN in france, or other non-U.S. PLMNs and non-chinese PLMNs. Other V-PLMNs are marked with V' -PLMNs.

Specifically, the terminal roams to the V '-PLMN before, the terminal or the roaming terminal group to which the terminal belongs performs a mobility procedure or a session procedure in another V-PLMN, in these procedures, V' -NF, V '-AF, V' -OAM, and the like of the V '-PLMN generate corresponding recorded data (or referred to as original data), and the V' -NWDAF collects different original data sets according to different analytical IDs, and performs data analysis on these original data sets to obtain an analysis result related to the analytical ID, that is, a data classification result 3. This data analysis result 3 is stored in the H-NWDAF or H-UDR/H-UDM and may be sent to the V-NWDAF as a second analysis result upon a V-NWDAF request.

The H-NWDAF obtains the data analysis result 3 for the specific analytical ID in the second request and optional information (such as filtering conditions, analysis object information, etc.), and feeds back the data analysis result 3 to the V-NWDAF. In one possible implementation, the data analysis result may be identified by visited place identification information of the terminal, which is used to indicate that the analysis result is a corresponding analysis result generated in the V' -PLMN. For example, for a certain terminal, the V '-NWDAF analyzes its traffic behavior characteristics from its corresponding original data set that was once in the V' -PLMN. Of course, in a possible implementation manner, if the V-NWDAF defines that the service behavior feature of the terminal only needs to be acquired on monday, the H-NWDAF only needs to feed back the service behavior feature of the terminal on monday in the V' -PLMN. For another example, for a roaming terminal group where a certain terminal is located, the V '-NWDAF analyzes the common service behavior characteristic of the group according to the original data set that the group once corresponds to in the V' -PLMN, and the H-NWDAF feeds back the common service behavior characteristic to the V-NWDAF. Of course, in a possible implementation manner, if the V-NWDAF defines that the service behavior characteristics of the group only need to be acquired within a certain area, the H-NWDAF only needs to feed back the common service behavior characteristics of the group of the terminal within the corresponding area of the V' -PLMN.

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

The first data refers to various related raw data collected from V-NF, V-AF, UE, V-OAM and the like according to optional filtering conditions for the V-NWDAF to include the related analytical ID and the object (such as the terminal) in the first request, and the various related raw data are used for data analysis of the V-NWDAF to generate a required analysis result. The process of collecting the first data of the visited place by the V-NWDAF is similar to the process of collecting the original data of the home place by the H-NWDAF, and is not described herein again.

208. And the V-NWDAF generates a first analysis result of the terminal in the V-PLMN of the visit place according to the first data collected in the V-PLMN and a second analysis result sent by the H-NWDAF.

Of course, the step 208 is only one way of generating the first analysis result, and other ways may be involved in the corresponding description in the step 103 of the embodiment corresponding to fig. 3 for understanding, and are not repeated herein.

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

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

In one possible implementation, the first response may be identified with visited-site identification information, such as V-PLMN ID and/or V-NWDAF, to indicate that the first analysis result is generated in the VPLMN or V-NWDAF.

In one possible implementation, the first response may be identified with home identification information, such as an H-PLMN ID and/or an H-NWDAF, indicating that the first analysis result is for a roaming terminal from the H-PLMN ID and/or the H-NWDAF.

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

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

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

It is noted that, in the absence of the first analysis result, the V-NF/V-AF/V-OAM/terminal already has some specific functions, for example, the PCF has a function of policy making, the AMF has a function of mobility management, the AF has a function of application layer message processing, etc., which can make a corresponding function policy before executing a corresponding function flow, and the V-NF/V-AF/V-OAM/terminal executes the corresponding function flow according to the corresponding function policy. In the method according to the embodiment of the 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 may formulate a corresponding enhancement policy based on the analysis result, and the corresponding enhancement policy may assist the V-NF/V-AF/V-OAM/terminal to better execute a corresponding functional process, such as improving the accuracy of the function, shortening the time delay of the process, and the like, so as to improve the user experience of the roaming terminal.

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 functional network element, and the policy control functional network element makes a service quality enhancement policy for the service of the terminal according to the service experience evaluation data of the terminal.

In a possible implementation manner, if the first analysis result is mobility analysis data of the terminal, and the first functional network element is a mobility management functional network element, the mobility management functional network element makes a mobility management enhancement policy for the terminal according to the mobility analysis data of the terminal.

In a possible implementation manner, the first analysis result is expected behavior analysis data of the terminal, and the first functional network element is a session management functional network element, and the session management functional network element makes a session management enhancement policy for the terminal according to the expected behavior analysis data of the terminal.

In the embodiment corresponding to fig. 4, the generation of the first analysis result by the V-NWDAF is described, and the sending of the first analysis result back to the H-PLMN for storage is further described in conjunction with the embodiment corresponding to fig. 5. Fig. 5 shows that two possible implementations are stored by sending the first analysis result back to the H-PLMN, wherein steps 301 to 304 are the first possible implementation and steps 401 to 406 are the second possible implementation. The following is described with reference to fig. 5, respectively.

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

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

The subscription request is for subscribing to a first analysis result of a terminal roaming from the H-PLMN to the V-PLMN.

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

In a possible implementation manner, the reporting condition in the subscription request may be set to be periodic reporting, such as reporting every month, or set to be event reporting, such as reporting an event that a gold medal user roams into the network, and the number of roaming users reaches a set value.

302. The V-NWDAF generates the relevant first analysis of the terminal using the method described in the corresponding embodiment of fig. 4.

Specifically, in a possible implementation manner, when the H-NWDAF subscribes to the first analysis result of the single roaming terminal, the V-NWDAF generates the relevant first analysis result of the single roaming terminal by using the method described in the embodiment corresponding to fig. 4;

in another possible implementation manner, when the H-NWDAF subscribes to the first analysis result of the roaming terminal group, the V-NWDAF generates the relevant first analysis result of the roaming terminal group by using the method described in the embodiment corresponding to fig. 4;

303. and judging whether the reporting condition is met, if so, executing the step 304, and if not, not executing the step 304.

The step 303 is not necessarily performed, and may be reported directly without judgment.

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

And the V-NWDAF reports the information according to the reporting condition in the subscription message. For example, it may be the reporting of a single terminal, or the reporting of a group of roaming terminals.

In one possible implementation, the first analysis result may be identified with identification information of the visited place, for example, with VPLMN id and/or V-NWDAF, for indicating that the first analysis result is generated in VPLMN or V-NWDAF.

In a possible implementation manner, the first analysis result may be further identified by identification information of a home, for example, by an H-PLMN ID and/or an H-NWDAF, for indicating that the first analysis result is for a roaming terminal from the H-PLMN ID and/or the H-NWDAF.

In one possible implementation, the first analysis result may be identified by a combination of the two.

Steps 301 to 303 describe a scheme for triggering a subscription request by an H-NWDAF, and the following describes a scheme for triggering a subscription request by an 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 for subscribing a first analysis result of a terminal roaming from the H-PLMN to the V-PLMN.

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

The function of the second subscription request may 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. The V-NWDAF generates the relevant first analysis of the terminal using the method described in the corresponding embodiment of fig. 4.

Specifically, in a possible implementation manner, when the V-UDM/V-UDR subscribes to a first analysis result of a single roaming terminal, the V-NWDAF generates a relevant first analysis result of the single roaming terminal by using the method described in the embodiment corresponding to fig. 4;

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

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

Of course, if the second subscription request includes the reporting condition, the V-NWDAF may send the first analysis result to the V-UDM/V-UDR according to the reporting condition.

405. The V-UDM/V-UDR can judge whether the reporting condition is met.

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

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

And the V-UDM/V-UDR reports according to the reporting condition in the subscription message. For example, it may be the reporting of a single terminal, or the reporting of a group of roaming terminals.

In one possible implementation, the first analysis result may be identified with home identification information, e.g., with VPLMN id and/or V-NWDAF, indicating that the first analysis result is generated in VPLMN or V-NWDAF.

In a possible implementation manner, the first analysis result may be further identified by identification information of a home, for example, by an H-PLMN ID and/or an H-NWDAF, for indicating that the first analysis result is for a roaming terminal from the H-PLMN ID and/or the H-NWDAF.

In one possible implementation, the first analysis result may be identified by a combination of the two.

It was described above that the first functional network element requests the first analysis result of the terminal by means of a first request. In fact, the first functional network element may not indicate the first analysis result of the requesting terminal when sending the first request. A scheme of data processing that does not indicate the first analysis result of the requesting terminal is described below with reference to fig. 6.

As shown in fig. 6, another embodiment of the method for data processing 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 for requesting a first analysis result.

The setting method of the first request in step 501 may specifically refer to the setting methods of the first requests in steps 101 and 204. For example:

in a possible implementation manner, the first request may include type identification information of the first analysis result, where the type identification information is used to identify a type of the first analysis result; thus, the first data analysis network element may generate the first analysis result corresponding to the type identifier information of the roaming terminal group according to the first request. The type identification information may participate in the understanding of the data analysis result 1, the data analysis result 2, and the data analysis result 3 in the above-described embodiment corresponding to fig. 4.

In a possible implementation manner, the first request may further include an analysis result or an event filter condition, which is used to indicate that a specific request is the first analysis result meeting the filter condition. If the filtration conditions are as follows: temporal filtering criteria, regional filtering criteria, business type filtering criteria, slice filtering criteria, DNN filtering criteria, and the like.

In a possible implementation manner, the first request may include second indication information and/or the home identification information, where the second indication information is used to indicate that the first request is used to request a first analysis result of a roaming terminal group, and the home identification information is used to indicate that the first request is used to request a first analysis result of a roaming terminal group from a home to which the home identification information corresponds.

The only difference is that the first request in step 501 does not indicate specific analysis object information, for example, a possible implementation manner may be that the first request does not carry a specific terminal identifier or group identifier, that is, the content of the analysis object information 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 carries the terminal id or group id or other information that can indicate the object to be analyzed.

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

502. And the first data analysis network element generates the first analysis result aiming at the roaming terminal group.

When the first request does not carry the specific terminal identifier or the specific terminal group identifier, that is, the first request does not accurately define the analysis object, the data analysis network element may also distinguish the analysis object, that is, collect and analyze the related data of the roaming terminal group separately to obtain the first analysis result applicable to the roaming terminal group, thereby ensuring that the subsequent first functional network element knows that the specific applicable object of the first analysis result is the roaming terminal.

The first analysis result may be generated in a manner that: first, a third analysis result is generated for each terminal in the group, for example: if there are N roaming terminals in the group, there are N third analysis results. And then generating a first analysis result according to the N third analysis results. And the third analysis result refers to a data analysis result generated by the first data analysis network element of the visited place to the single roaming terminal at the visited place. The first analysis result may be a feature of commonality extracted from the N third analysis results.

In a possible implementation, this step 502 may be preceded by determining, by the first data analysis network element, the roaming terminal group. In a possible implementation manner, the first request includes second indication information or/and the home identifier information, the second indication information is used to indicate that the first request is used to request a first analysis result of a roaming terminal group, and the home identifier information is used to indicate that the first request is used to request a first analysis result of a roaming terminal group from a home to which the home identifier information corresponds. And the first data analysis network element determines the roaming terminal group according to the second indication information or/and the attribution identification information.

In another possible implementation manner, the first data analysis network element may obtain the home identifier of the terminal by associating with the original data generated by the terminal at the visited place, and determine that the terminal is a roaming terminal according to that the home identifier of the terminal is different from the visited place identifier where the terminal is located, and the plurality of roaming terminals may be classified into a roaming terminal group. Further, the first data analysis network element may classify terminals with the same home identifier as the same roaming terminal group.

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

The second functional network element may be the NF network element, the AF network element, the OAM network element or the terminal belonging to the visited place, which is described above. The first data is process/result data generated in the terminal itself, the visited network, the visited business server, etc. when the terminal executes the mobility flow or session flow in the visited network. One possible implementation may be: step 5012 is performed before step 502: the first data analysis network element receives second data of the terminal from a third functional network element, wherein the third functional network element belongs to the attribution place of the terminal;

accordingly, step 502 is: and 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, the AF network element, the OAM network element, etc. belonging to the home location described above. The second data refers to process/result data generated in the home network, the home service server, and the like when the terminal executes the mobility procedure or the session procedure in the visited network.

One possible implementation may be: step 5013 is performed before step 502: the first data analysis network element receives a second analysis result of the terminal from a second data analysis network element or a first data storage network element, and the second data analysis network element or the first data storage network element belongs to a home of the terminal.

Accordingly, step 502 is: and 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 may be generated by combining the first data, the second data, and the second analysis result. Such as:

and generating a first analysis result according to the first data and the second data.

And generating a first analysis result according to the first data and the second analysis result.

And generating a first analysis result according to the second data and the second analysis result.

And generating a first analysis result according to the first data, the second data and the second analysis result.

Of course, the manner of acquiring the first data, the second data, and the second analysis result is the same as that described in the above one possible implementation manner, and details are not 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 at the home, and an analysis result type corresponding to the second analysis result is the same as an analysis result type corresponding to the first analysis result. For example, the first analysis result refers to the service MOS analysis result of the visited place V-NWDAF on application1, and the second analysis result refers to the service MOS analysis result of the home place H-NWDAF on application 1.

In a possible implementation manner, the second analysis result is an analysis result generated by the second data analysis network element on the roaming terminal group at the home. For example, the second analysis result is a service MOS analysis result generated by application1 of the home H-NWDAF on the roaming terminal group, where the second data analysis network element may determine, according to the instruction of the first data analysis network element, which roaming terminal group is specifically acquired as the second analysis result of the home.

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 at the visited place. It is noted that the second analysis result is the analysis result which is generated by the first data analysis network element at the corresponding visited place for the roaming terminal group and is sent and stored in the home of the roaming terminal group.

In a possible implementation manner, the second analysis result is an analysis result generated by a fourth data analysis network element on a visited place of the roaming terminal group corresponding to the fourth data analysis network element, where the visited place corresponding to the fourth data analysis network element is different from a visited place corresponding to the first data analysis network element or the second data analysis network element. It is noted that the second analysis result is the analysis result which is generated by the fourth data analysis network element at the corresponding visited place for the roaming terminal group and is sent and stored in the home of the roaming terminal group.

The obtaining mode of the second analysis result may be:

and 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 roaming terminal group.

The first data analysis network element sends a second request to the second data analysis network element or the first data storage network element, where the second request is used to request the second analysis result;

and 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, wherein the second response comprises the second analysis result.

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

In a possible implementation manner, the second request further includes type identification information of the second analysis result, where the type identification information is used to identify a type of the second analysis result; and 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 a second analysis result of the roaming terminal group.

The second request also comprises the visiting place identification information of the visiting place. The visitor location identification information is used to specify the identity of the second request sender, in other words, to inform the processing object of the second request of the request subject of the second data analysis result.

The visitor identification information includes one or more of the following: public land mobile network PLMN identification information (PLMN ID) of the visited place, identification information (NWDAF ID) of the data analysis network element of the visited place, or regional information of the visited place, which can refer to in which region of the visited place, such as shenzhen city in guangdong province.

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

the data type of the first data and the second data is related to the required first analysis result, such as the analysis result related to the service of the terminal is requested, and the first data and the second data are the data related to the service directly or indirectly in the related functional network element; if the request is the analysis result related to the abnormal behavior of the terminal, the first data and the second data are the data which are directly or indirectly related to the abnormal behavior of the user in the related functional network element; if other types of analysis results are requested, the first data and the second data are the corresponding types of data.

In fact, the second analysis result may also be an analysis result of the visited place to which the roaming terminal group has been visited, and the data analysis result is generated by the data analysis network element of the visited place to which the roaming terminal group has been visited and is sent to the home place for storage. Such as: the roaming terminal group belongs to the shanghai area, the roaming terminal group currently roams to the beijing area, and the roaming terminal group also roams to the guangdong area before the shanghai area, so that the second analysis result may be the analysis result of the guangdong area. It should be noted that the visited place where the terminal has visited may be the same as or different from the visited place currently visited. Take the example that the visited place can be different from the current visited place:

the above procedure 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 further include the home identification information of the roaming terminal group. The home identification information is used to indicate that the second analysis result is from a home.

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 in the second response, and the implementation method is specifically multiple. For example, in a possible implementation manner, if there is an analysis result of the visited place, the analysis result of the visited place is sent first; if the analysis result of the attribution is not sent again; if neither of them is present, a null message is sent or no second analysis result is indicated. For another example, in another possible implementation, when there are both the analysis result once visited and the analysis result of home, both may be sent simultaneously. For another example, in another possible implementation manner, it may further refine to distinguish whether the visited place is the visited place where the roaming terminal group is currently located, and send the following analysis results as a second analysis result from high to low in priority: the current visit place of the roaming terminal group generates an analysis result for the roaming terminal group, the home place generates an analysis result for the roaming terminal group, other visit places generate an analysis result for the roaming terminal group, and the null message indicates that no second analysis result exists. Of course, other specific implementations exist and are not listed here.

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

The first response includes the first analysis result, and further includes first indication information or home identification information, where the first indication information is used to indicate that the first data analysis result is generated for a roaming terminal group, and the home identification information is used to indicate that the first data analysis result is generated for the roaming terminal group of the home.

It should be noted that the embodiment described in fig. 6 is substantially the same as the embodiment corresponding to fig. 3 to fig. 5, and the difference between this embodiment and the foregoing embodiment is that the first functional network element explicitly indicates a terminal, which may be a single terminal or a roaming terminal group, in the embodiment described in fig. 3 to fig. 5.
