specific Embodiment

[0083] NWDAF registers with NRF as image 3 shown;

[0084] NWDAFs at different levels register with NRF according to the method defined in the 3GPP standard protocol, including the following steps:

[0085] NWDAF sends registration or renewal request to NRF.

[0086] The NWDAF network function sends a registration or update request message to NRF, and the registration or update request message carries at least one of the following messages: NWDAF network function type, NWDAF network function identifier, NWDAF supported business capabilities, NWDAF service area information; NWDAF service area The information includes at least one of the following parameters: slice information of the service, network function identifier of the service, and location information of the service. Wherein, the service slice information is used to represent the slice of the service. For example: through the slice information served by the NWDAF and the slice information to which the network functi...

Abstract

The invention provides a data analysis method based on a 5G network and a matched NRF information processing method. According to the data analysis method based on the 5G network and the matched NRF information processing method, the NRF is used for selecting the reasonable NWDAF for data analysis according to the mobility of the UE, and therefore the data analysis method based on the 5G network is suitable for a multi-NWDAF deployment scene, and waste of network resources and service delay are reduced.

Description

technical field [0001] The present invention relates to the field of 5G network, in particular to data analysis based on 5G network, NWDAF service request and supporting NRF method. Background technique [0002] In the fifth generation mobile communication (5th Generation, 5G) system, a network data analysis function (Network Data Analytics Function, NWDAF) is introduced. NWDAF can collect network data from the network management function (Operations Administration and Maintenance, OAM), application function (Application Function, AF) and 5G network function (Network Function, NF), and analyze the network data and feed back the network data analysis results. [0003] Such as figure 1 as shown, figure 1 It is a schematic diagram of the overall framework of 5G network automation. figure 1 Describes NWDAF collecting data from operator OAM, AF, and other 5G network functions. For the collection of OAM data, NWDAF can reuse the existing mechanisms and interfaces defined by th...
