Abstract: Embodiments of the present application provide a location management method, a control plane node, and user equipment. A first control plane node determines first location area management information of UE, where the first location area management information includes N levels of location area identity lists, and a periodic time value PTV and a reachable time value RTV that correspond to each level of location area identity list in the N levels of location area identity lists; and performs paging management based on the first location area management information. In a process of performing the paging management, the first control plane node determines a paging area in areas to which the N levels of location area identity lists belong, and performs the paging management only in the paging area, instead of performing the paging management in all the areas corresponding to the N levels of location area identity lists.

Abstract: This application provides example key management methods and example communication apparatuses. In an example method, a terminal device obtains identification information of a first decryption network element in a local network. The terminal device obtains, based on the identification information and a mapping relationship, a first encryption key corresponding to the first decryption network element, where the mapping relationship indicates at least one decryption network element and an encryption key corresponding to each of the at least one decryption network element, and the at least one decryption network element includes the first decryption network element. The terminal device encrypts the user identity information by using the first encryption key, to obtain a hidden user identity. The terminal device sends a registration request to the local network through an access network device, where the registration request includes the hidden user identity.

Abstract: Embodiments of this application provide a communication method and an apparatus to resolve a PC5 unicast establishment failure due to inconsistency between security parameters of terminal devices in a V2X scenario with security negotiation introduced into a PC5 unicast establishment procedure. The communication method includes: A first direct communication discovery name management function network element obtains a security parameter of a first terminal device. A security parameter is required for establishing a PC5 connection between the first terminal device and a second terminal device. The first direct communication discovery name management function network element receives a security parameter of the second terminal device from a second direct communication discovery name management function network element and determines, based on whether the security parameter of the first terminal device matches the security parameter of the second terminal device, whether the first terminal device and the second terminal device support mutual communication.

Abstract: An address obtaining method includes obtaining, by a third network device, an identifier of a first application from a terminal device. The identifier of the first application indicates a request for obtaining an address of an instance of the first application. The address obtaining method further includes sending, by the third network device, a first message to a first network device, wherein the first message comprises the identifier of the first application, and the first message is useable to request the address of the instance of the first application. The address obtaining method further includes receiving, by the third network device, the address of the instance of the first application from the first network device, and sending the address of the instance of the first application to the terminal device.

Abstract: The present disclosure relates to user plane information reporting methods and apparatus. In one example method, a session management network element obtains parameter information, and initiates establishment of a dedicated tunnel between a first communications apparatus and a second communications apparatus, where the parameter information indicates the first communications apparatus to report user plane information when a reporting condition is met. The session management network element sends a first rule to the first communications apparatus, where the first rule indicates the first communications apparatus to send a packet to the second communications apparatus through the dedicated tunnel when the reporting condition is met.

Abstract: Embodiments of this application provide a method, an apparatus, and a system for reporting data usage, so that for a PDU session into which a UL CL user plane network element or a BP user plane network element is inserted, statistics can be accurately collected on data usage. The method includes: An aggregate user plane network element determines discarded data usage of the aggregate user plane network element, and sends the discarded data usage to a session management network element. The first session management network element receives the discarded data usage, and receives transport data usage of one or a plurality of anchor user plane network elements, which are anchor user plane network elements connected to the aggregate user plane network element. The first session management network element determines actual data usage of a terminal device based on the discarded data usage and the transport data usage.

Abstract: Example methods for controlling access of a terminal to a network and a network element are described. One example method includes detecting whether a target terminal is exposed to a security threat and sending a message to a storage function network element based on a detection result. The message includes device information and network access indication information, the device information indicates at least one terminal including the target terminal, and the network access indication information indicates that the at least one terminal is allowed or forbidden to access a network. Thus the security function network element outputs an allowed or forbidden indication to the storage function network element, and the storage function network element controls, based on the foregoing indication, access of the terminal to the network.
