Description

Information acquisition method and device

Technical Field

The application belongs to the technical field of communication, and particularly relates to an information acquisition method and device.

Background

Network data analysis functions (Network Data Analytics Function, NWDAF) are introduced in 3GPP, which have a certain artificial intelligence (Artificial Intelligence, AI) analysis function. For example, NWDAF can provide an observation service experience-related data analysis function; the NWDAF may collect information of quality of service (Quality of Service, qoS) when the terminal accesses a certain server, such as uplink and downlink rate, packet loss rate, etc., and output a piece of statistical information or prediction information; the statistical information comprises user experience conditions of the terminal accessing the server; the NWDAF may also predict according to the historical experience situation of the terminal accessing the server; for example, if the terminal accesses the server in a certain area in a certain time period in the future, the terminal experiences the situation.

In general, for the analysis or prediction content that can be provided by the NWDAF, the analysis number (analytical ID) is used to distinguish, if a network element wants to obtain the analysis or prediction result of the NWDAF, the network element, as a service consumer, can indicate to the NWDAF that the analysis or prediction is to be provided by using different analytical IDs and some parameters. However, NWDAF needs to collect relevant data from a core network element, a third party server or User Equipment (UE) and so on to complete the relevant analysis or prediction; for example, the above-described observation service experience-related data analysis requires data to be collected from the user plane function (User Plane Function, UPF), and QoS-related data to be collected from the UPF, such as uplink and downlink rates, packet loss rates, and the like.

In the related art, the NWDAF may request to analyze a service of a single UE, or may analyze a service of a plurality of UEs, for example, when requesting an arbitrary terminal (any UE), it is to request to analyze a service of a UE of a whole network of an operator. In the case of analyzing the traffic of multiple UEs, for example, a network element is used as the initiator of the analysis request, i.e. the consumer of NWDAF service, the network element needs to provide parameters such as data network name (Data Network Name, DNN), single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-nsai), data network access identifier (DN Access Identifier, DNAI), server IP address and UE location of interest, and these parameters are usually aimed at more precisely determining or screening eligible UEs from any UEs. Using the above parameters, NWDAF can determine the range of potential multiple UEs, e.g., all UEs accessing a certain DN, or all UEs establishing an internet protocol (Internet Protocol, IP) with an application server; the NWDAF can find out which session management functions (Session Management Function, SMF) the potential UEs are controlled to, which SMF can determine the UPF so that the NWDAF can collect data from the UPF.

However, when the network element does not provide parameters such as DNN, S-nsai, and DNAI (because the parameters are optional parameters, not mandatory), how to obtain the parameters is a problem to be solved. Without the parameters described above, the NWDAF cannot determine the potential terminals that require data acquisition and cannot provide accurate analysis results.

Optionally, the target mapping relationship between the first information and the second information may include at least one of:

1) The first mapping relation is used for indicating the mapping relation between the IP address of the application server and the second information;
