Abstract: This application discloses an NF management method and an NF management device, to perform centralized management on discovery and access between NF components, thereby facilitating a normal network operation. The method in embodiments of this application includes: receiving an NF discovery request sent by a first NF component, where the NF discovery request includes a second NF identifier, and the second NF identifier is used to indicate a second NF; obtaining component information of a second NF component based on the second NF identifier, where the second NF component has the second NF, and the component information includes a discovery policy of the second NF component and a second NF component identifier; determining, based on the discovery policy in the component information, whether the first NF component can access the second NF component; and if yes, sending the second NF component identifier to the first NF component.

Abstract: In a network function (NF) management method, a NF management device receives an NF discovery request sent by a first NF component, where the NF discovery request includes a second NF identifier that indicates a second NF. The NF management device obtains component information of a second NF component based on the second NF identifier, where the second NF component has the second NF, and the component information includes a discovery policy of the second NF component and a second NF component identifier. The NF management device determines, based on the discovery policy in the component information, that the first NF component can access the second NF component, and sends the second NF component identifier to the first NF component.

Abstract: This application discloses a network slice selection method and apparatus, to resolve a prior-art problem of large transmission load on a network side. The method performed by a core network device includes: receiving a first request message sent by a terminal device, where the first request message is used to request to allocate, to the terminal device, a network slice that provides a business service; sending a query message to a SSF, where the query message carries user information of the terminal device, and is used to query for a network slice that is capable of providing a business service for the terminal device; and after receiving slice information of the network slice that is capable of providing the business service required by the terminal device and that is determined based on the user information, forwarding the first request message to the network slice corresponding to the slice information.

Abstract: Embodiments of the present invention provide a message processing method and apparatus, and relate to the field of communications technologies. The method includes: comparing a message feature of a currently processed message with a specified tracking feature; determining a user corresponding to the message as a target user when determining that the message feature matches the tracking feature; and reporting a signaling message of the target user to a network management server. In the present invention, a network fault is quickly located, and network connection efficiency is improved.

Abstract: In a network function (NF) management method, a NF management device receives an NF discovery request sent by a first NF component, where the NF discovery request includes a second NF identifier that indicates a second NF. The NF management device obtains component information of a second NF component based on the second NF identifier, where the second NF component has the second NF, and the component information includes a discovery policy of the second NF component and a second NF component identifier. The NF management device determines, based on the discovery policy in the component information, that the first NF component can access the second NF component, and sends the second NF component identifier to the first NF component.
