Description

User information registration method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for registering user information. Background At present, the traditional mode of registering the registration information of the terminal equipment has uniqueness, namely, one network element serves one terminal equipment and registers the registration information of the terminal equipment into a database. When the terminal equipment is transferred between network elements, the old network element can transfer the registration information of the terminal equipment to the new network element, and the new network element can re-register or update the registration information of the terminal equipment into a database. Currently, when a terminal is served by a Network DATA ANALYTIC Function (NWDAF), the Network data analysis Function also needs to register registration information of the terminal device with a database. Since a plurality NWDAF can serve the same terminal device, a plurality NWDAF may cause overlapping registration information between different NWDAF when registering registration information of the terminal device with the database. Disclosure of Invention The embodiment of the application provides a method and a device for registering user information, which are used for solving the problem of mutual coverage between registration information caused by registering registration information of terminal equipment to UDM (user data management) by a plurality of NWDAF. In a first aspect, an embodiment of the present application provides a method for registering user information, including: The network data analysis function NWDAF obtains registration information of the terminal device; The NWDAF sends a registration request to a unified data management function (UDM), wherein the registration request comprises the registration information and positioning information for identifying a storage path of the registration information in the UDM, and the positioning information comprises an identification of the NWDAF. Based on the above scheme, by adding NWDAF identifiers to the positioning information sent to the UDM, so that the information registered by different NWDAF can be stored in different positions in the UDM, it is possible to prevent the registration information from overlapping each other between different NWDAF. In some embodiments, the location information is a resource location identifier, URI. In some embodiments, the location information further includes an event analysis identifier, where the event analysis identifier is used to indicate the first service performed by the NWDAF for the terminal device, and the registration information is generated when the NWDAF provides the first service for the terminal device. Based on the above scheme, the event analysis identifier is added in the positioning information, so that data corresponding to different services provided by NWDAF for the terminal device can be stored in different positions, and further registration information belonging to the same event analysis identifier between different NWDAF is prevented from being mutually covered. In some embodiments, after the NWDAF sends a registration request to the UDM, the method further comprises: And NWDAF, when the registration information is determined to be updated, sending an update request to the UDM, wherein the update request comprises updated registration information and the positioning information and is used for indicating the UDM to update the registration information in a storage path indicated by the positioning information into the updated registration information. Since the registration information of the plurality NWDAF uses the same positioning information in the prior art, updating the registration information by one NWDAF may affect other registration information of NWDAF. In the application, the registration information of a specific one NWDAF can be updated in a targeted manner according to the identifier NWDAF contained in the positioning information, other NWDAF registration information is not affected, and the occurrence of update errors is avoided. In some embodiments, after the NWDAF sends a registration request to the UDM, the method further comprises: and when the NWDAF determines that the registration information needs to be deleted, sending a deletion request to the UDM, wherein the deletion request comprises the positioning information and is used for indicating the UDM to delete the registration information in a storage path indicated by the positioning information. In the prior art, since the registration information of the plurality NWDAF is stored in the same storage path, when the UDM deletes the registration information, the information registered in the plurality NWDAF in the storage path may be deleted. By adding NWDAF identifiers into the positioning information, the UD
