According to the data acquisition method provided by the embodiment of the application, under the condition that the first communication equipment belonging to the first network acquires the user permission of the target terminal belonging to the second network, the data corresponding to the target terminal roaming in the first network is acquired based on the user permission of the target terminal, so that the acquisition of the data corresponding to the target terminal roaming by the roaming network is realized, the data corresponding to the target terminal roaming by the roaming network is conveniently analyzed and processed, and the service quality of the target terminal roaming is evaluated based on the analysis and processing result.

The data acquisition method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 2 is a schematic flow chart of a data acquisition method according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:

step 201, a first communication device acquires a user license of a target terminal; the first communication device is attributed to a first network, the target terminal roams in the first network, and the target terminal is attributed to a second network different from the first network.

Wherein the first communication device may comprise an NWDAF attributed to the first network or a data collection coordination function (Data Collection Coordination Function, DCCF) attributed to the first network; since the first communication device belongs to the first network and the target terminal belongs to the second network, if the target terminal roams in the first network, the first network may be referred to as a roaming network and the target terminal may be referred to as a roaming terminal.

For example, if the first communication device wants to acquire the data of the target terminal roaming in the first network, the first communication device needs to acquire the user permission of the target terminal first, and only if the user permission of the target terminal is successfully acquired, the first communication device has the right to acquire the data of the target terminal roaming in the first network.

Step 202, the first communication device obtains data corresponding to the target terminal based on the user permission of the target terminal.

The data corresponding to the target terminal may be network data and/or terminal data of the target terminal.

For example, when the first communication device obtains the user permission of the target terminal, it may determine that the first communication device has the right to obtain the data corresponding to the target terminal roaming in the first network at this time, and further obtain the data corresponding to the target terminal roaming in the first network, where the data may be any data of the target terminal when the target terminal operates in the first network, for example, the data may be user connection management data, mobility management data, session management data, accessed service data, resource usage data of a network slice, user service experience data and the like.

It should be noted that, the present application is not limited to this, and the first communication device may acquire data of one target terminal roaming in the first network, or may acquire data of a plurality of target terminals roaming in the first network.

Optionally, fig. 3 is a second flowchart of a data acquisition method according to an embodiment of the present application, as shown in fig. 3, after performing step 202, the method further includes the following steps:

and 203, the first communication device performs target processing on the data corresponding to the target terminal.

Wherein the target process comprises at least one of: traffic analysis of network slices, resource demand analysis of network slices, user traffic experience analysis of network slices, sustainability analysis of quality of service QoS, quality of experience (Quality of Experience, qoE) of traffic and traffic path analysis and network performance analysis.

Taking a first communication device as a DWDAF of a first network as an example, when the DWDAF of the first network acquires data corresponding to a target terminal roaming in the first network, corresponding processing is carried out based on the type of the data; for example, when the data corresponding to the target terminal includes user connection management data, mobility management data, session management data, access service data, and the like, the DWDAF of the first network evaluates and analyzes different types of users using a network performance analysis and prediction model by collecting the user connection management data, the mobility management data, the session management data, and the access service data, constructs a user figure, determines a movement track and a service usage habit of the user, and predicts a user behavior, and the first network optimizes a user mobility management parameter, a radio resource management parameter, and the like based on the analysis and prediction data.

For another example, when the data corresponding to the target terminal includes resource usage data, traffic data, user service experience data, and the like of the network slice, the DWDAF of the first network uses the network performance analysis and prediction model to implement statistics and prediction of the traffic volume, the resource requirement, and the user service experience of the network slice by collecting the resource usage data, the traffic data, and the user service experience data of the network slice, constructs a network slice portrait, and optimizes the network slice resource allocation and the network slice selection policy.

For another example, when the data corresponding to the target terminal includes network performance data, specific area traffic load data, user traffic experience data, and the like, the DWDAF of the first network evaluates and analyzes different types of traffic by collecting the network performance data, the specific area traffic load data, the user traffic experience data, and the like, using a network performance analysis and prediction model, constructing a traffic figure, determining QoE and traffic path of the traffic, and internal association such as 5G QoS, optimizing the traffic path (e.g., optimizing UPF selection), optimizing the traffic route (optimizing UE routing policy urs), optimizing 5G edge calculation, optimizing the traffic corresponding 5G QoS, and the like.

As another example, the internet of vehicles is an important technology of the 5G network, and in an automatic driving scenario of the internet of vehicles, prediction of network performance (e.g., qoS information, traffic load) of a base station through which the vehicle is going to pass has an important role in improving the quality of service of the internet of vehicles. For example, the internet of vehicles server may determine whether to continue to maintain the unmanned mode based on predictive information of network performance. When the data corresponding to the target terminal comprises network performance data, specific area business load data and the like, the NWDAF of the first network is used for realizing statistics and prediction of network performance by collecting the network performance data and the specific area business load data and utilizing a network performance analysis and prediction model, and assisting AF optimization parameters.

According to the data acquisition method provided by the embodiment of the application, when the first communication equipment belonging to the first network acquires the data corresponding to the target terminal roaming in the first network, the data can be analyzed and processed, and the service quality of the target terminal roaming in the first network is further evaluated based on the analysis and processing result.

Optionally, fig. 4 is a third flowchart of a data acquisition method according to an embodiment of the present application, as shown in fig. 4, before performing step 201, the method further includes the following steps:

step 204, the first communication device receives a first request message sent by a second communication device; the second communication device belongs to the first network, and the first request message is used for requesting to acquire a result of performing target processing on data corresponding to the target terminal.

Wherein the second communication device comprises a consumer network function entity belonging to the first network, e.g. an AMF belonging to the first network, an SMF belonging to the first network, or a PCF belonging to the first network.

Optionally, the first request message includes at least one of: roaming indication information, an identification of the second network to which the target terminal belongs, a target area of the second network to which the target terminal belongs, a target time of the target terminal in the first network, and an identification of the target terminal; the roaming indication information is used to indicate that the result of the target processing is with respect to the target terminal roaming in the first network.

The first request message may be the following signaling: the analysis result is subscribed to the nnwdaf_analyticingsubscription_subscription, or the analysis information Request nnwdaf_analyticinfo_request.

For example, when the second communication device belonging to the first network needs to obtain the analysis result of the data corresponding to the target terminal roaming in the first network, the first communication device belonging to the first network needs to send a first request message to the first communication device, where the first request message is used to request to obtain the result of performing target processing on the data corresponding to the target terminal, so that the first communication device receives the first request message sent by the second communication device.

Specifically, in the case that the first communication device receives the first request message sent by the second communication device, the first communication device obtains the user permission of the target terminal based on the first request message.

In addition, the information included in the first request message and its role may be as follows: acquiring a processing result of data corresponding to the target terminal based on the identification of the target terminal; determining a processing result of data corresponding to a target terminal which roams to the first network to be acquired based on the roaming indication information; determining a processing result of data corresponding to a target terminal which roams to the first network and belongs to the second network based on the identifier of the second network and the roaming indication information; determining a processing result of data corresponding to a target terminal which needs to obtain the target terminal which roams to the first network and belongs to the target area of the second network based on the identification of the second network, the roaming indication information and the target area of the second network; and determining a processing result of data corresponding to the target terminal which is required to acquire the target time and roams in the first network and belongs to the target area of the second network based on the identification of the second network, the roaming indication information, the target area of the second network and the target time of the target terminal in the first network.

It should be noted that, the first request message may further include at least one of the following: analysis result identification for indicating which analysis result is required, network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI) and data network name (Data Network Name, DNN); for example, if the analysis result is identified as the network performance analysis result, the first communication device only needs to analyze and process the network performance of the target terminal roaming in the first network.

According to the data acquisition method provided by the embodiment of the application, the first communication equipment acquires the data corresponding to the target terminal roaming in the first network based on the user permission of the target terminal under the condition that the first request message sent by the second communication equipment is acquired, so that the data corresponding to the target terminal is processed, and the first communication equipment is not required to actively process the data corresponding to the target terminal.

Optionally, the first communication device may obtain the user permission of the target terminal based on the first request message specifically by:

the first communication device determining a third communication device storing user permissions of the target terminal based on the first request message; the first communication device sends a second request message to the third communication device; the second request message is used for requesting to acquire the user permission of the target terminal; the first communication device receives the user permission of the target terminal sent by the third communication device.

Wherein the third communication device comprises an access mobility management function AMF belonging to the first network or a unified data management UDM belonging to the second network.

Optionally, the second request message includes at least one of: roaming indication information, an identification of the second network to which the target terminal belongs, a target area of the second network to which the target terminal belongs, a target time of the target terminal in the first network, an identification of the first network, and an identification of the target terminal; the roaming indication information is used to indicate that the result of the target processing is with respect to the target terminal roaming in the first network.

The second request message may be the following signaling: the subscription data Nudm SDM Get is requested.

For example, when the first communication device receives the first request message sent by the second communication device, the first communication device parses the first request message to obtain information carried in the first request message, for example, parses the identifier of the target terminal carried in the first request message, then the first communication device may determine a third communication device storing the user permission of the target terminal based on the identifier of the target terminal, and send a second request message requesting to obtain the user permission of the target terminal to the third communication device, so that when the third communication device receives the second request message, the third communication device obtains the user permission of the target terminal based on the information carried in the second request message, and sends the user permission of the target terminal to the first communication device, so that the first communication device obtains the user permission of the target terminal.

Wherein the fourth communication device belongs to the first network or the second network; the fourth communication device may be an NRF belonging to the first network or an NRF belonging to the second network; the information of the third communication device may be an identification of the third communication device.

Optionally, the third request message includes at least one of: roaming indication information, an identification of the second network to which the target terminal belongs, a target area of the second network to which the target terminal belongs, a target time of the target terminal in the first network, an identification of the first network, and an identification of the target terminal; the roaming indication information is used to indicate that the result of the target processing is with respect to the target terminal roaming in the first network.

The third request message may be the following signaling: the Request discovers NF nnrf_nfdiscovery_request.

When receiving a first request message sent by a second communication device, the first communication device analyzes the first request message to obtain information carried in the first request message, for example, analyzes the first request message to carry an identifier of a target terminal, roaming indication information and an identifier of a second network to which the target terminal belongs; in the case where the fourth communication device includes an NRF belonging to the first network, the first communication device may generate a third request message based on the identification of the target terminal, the roaming indication information, and the identification of the second network to which the target terminal belongs, and transmit the third request message to the NRF of the first network, so that the NRF of the first network determines whether the first communication device can acquire information storing the third communication device licensed by the user of the target terminal based on the roaming indication information and the identification of the second network to which the target terminal belongs when receiving the third request message; when the first communication device is determined to be capable of acquiring the information of the third communication device, the fourth communication device sends the information of the third communication device to the first communication device; in the case that the fourth communication device includes an NRF belonging to the second network, the first communication device may generate a third request message based on the identifier of the target terminal, the roaming indication information, the identifier of the second network to which the target terminal belongs, and the identifier of the first network, and send the third request message to the NRF of the second network, so that when the NRF of the second network receives the third request message, it is determined whether the first communication device may acquire information of the third communication device storing the user permission of the target terminal based on the roaming indication information, the identifier of the second network to which the target terminal belongs, and the identifier of the first network; when the first communication device is determined to be capable of acquiring the information of the third communication device, the fourth communication device sends the information of the third communication device to the first communication device.

In addition, the fourth communication device can query the information of the third communication device storing the user license of the target terminal because each UDM or AMF can register in advance in the NRF, that is, register the user license of the target terminal stored in each UDM, register the user license of the target terminal stored in each AMF; thus, when the fourth communication device receives the third request message, the information of the third communication device permitted by the user of the storage target terminal can be queried in the corresponding storage position.

In the case where the fourth communication device includes the NRF belonging to the second network, when the first communication device belonging to the first network transmits the third request message to the NRF belonging to the second network, the first communication device belonging to the first network may transmit the third request message to the NRF belonging to the second network sequentially through the secure edge protection proxy (Security Edge Protection Proxy, SEPP) belonging to the first network and SEPP belonging to the second network.

It should be noted that the information carried in the third request message may be the same as the information carried in the second request message, and the effect of each specific piece of information in the third request message is similar to the effect of each piece of information in the second request message, except that the second request message requests the user permission of the target terminal, and the third request message requests the third communication device storing the user permission of the target terminal.

Optionally, the obtaining, by the first communication device, the data corresponding to the target terminal based on the user permission of the target terminal in step 202 may be specifically implemented by:

the first communication device sending a fourth request message to a fifth communication device based on a user permission of the target terminal; the fourth request message is used for requesting to acquire the data corresponding to the target terminal;

and the first communication equipment receives the data corresponding to the target terminal sent by the fifth communication equipment.

For example, when the first communication device acquires the user permission of the target terminal, a fourth request message for requesting to acquire the data corresponding to the target terminal may be sent to the fifth communication device, and when the fifth communication device receives the fourth request message, the data corresponding to the target terminal is acquired based on the fourth request message and the data corresponding to the target terminal is sent to the first communication device, so that the first communication device acquires the data corresponding to the target terminal roaming in the first network.

It should be noted that the information carried in the fourth request message may be the same as the information carried in the second request message, and the effect of each specific piece of information in the fourth request message is similar to that of each piece of information in the second request message, except that the second request message requests the user permission of the target terminal, and the fourth request message requests the data corresponding to the target terminal roaming in the first network.

Optionally, after performing step 203, the data acquisition method further comprises the steps of:

and the first communication equipment sends a result of performing target processing on the data corresponding to the target terminal to the second communication equipment.

For example, after performing target processing on data corresponding to a target terminal roaming in a first network, the first communication device sends a target processing result to the second communication device, so that the second communication device can evaluate the service quality of the target terminal roaming in the first network based on the target processing result.

Fig. 5 is a flowchart of a data acquisition method according to an embodiment of the present application, as shown in fig. 5, the data acquisition method includes the following steps:

Step 501, the second communication device receives a result of performing target processing on data corresponding to the target terminal, which is sent by the first communication device; the first communication device and the second communication device belong to a first network, the target terminal roams in the first network, and the target terminal belongs to a second network different from the first network.

Wherein the second communication device may be a consumer NF, e.g. an AMF belonging to the first network, an SMF belonging to the first network, or a PCF belonging to the first network.

When the first communication device acquires the data corresponding to the target terminal roaming in the first network, the first communication device performs corresponding processing based on the type of the data, and sends a result of the target processing to the second communication device, so that the second communication device acquires the result of the target processing of the data corresponding to the target terminal roaming in the first network.

For example, in the case that the third communication device includes an AMF belonging to the first network, when the AMF of the first network receives the second request message sent by the first communication device, the AMF of the first network searches for the user permission of the target terminal in a terminal context (UE context) list based on the identifier of the target terminal carried in the second request message. The terminal context list in the AMF may include a Field (Field) and a Description tag (Description) corresponding to the Field, a user permission of the target terminal is added to a location corresponding to the Field, and contents of the user permission of the target terminal are added to a location corresponding to the Description tag.
