Abstract: The present disclosure relates to the field of wireless communications technologies, and provides a communication method. The method includes: receiving, by a control plane entity (CPE), a request message, where the request message includes identification information of user equipment (UE); determining, by the CPE, whether a suspend function of the UE corresponding to the identification information is allowed to be enabled; and if the CPE determines that the suspend function of the UE is allowed to be enabled, sending, by the CPE, a message to a radio access network node (RAN node) connected to the UE, where the message includes indication information indicating that the suspend function is allowed to be enabled.

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: In a control plane connection management method, a core network function entity determines, based on a service requirement of a service, information about a first connection requirement for a control plane connection of a terminal. The first connection requirement is for activating the control plane connection between the terminal and an access and mobility management function entity. The core network entity constructs a first control plane requirement message that contains identifier information of the terminal and the information about the first connection requirement. The core network entity then sends the first control plane requirement message to the access and mobility management function entity to instruct the access and mobility management function entity to activate the control plane connection of the terminal.
