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 discloses a method for implementing a user plane security policy, an apparatus, and a system. In an implementation, a terminal apparatus may associate or establish a PDU session based on user plane security indication information that is of an application and that is sent by a network device. In another implementation, a PCF adds an obtained user plane security attribute requirement of the application to a PCC rule and sends the PCC rule to an SMF, so that the SMF performs QoS flow binding based on the user plane security attribute requirement. According to the foregoing method, the user plane security attribute requirement of the application can be met.

Abstract: A routing rule obtaining method, device, and system are provided. The method is applied to an MEC system and performed by a data bus controller, including: obtaining service information of at least one service in the MEC system, where service information of each service includes a service type and a service identity; generating a routing rule according to the service information of the at least one service, where the routing rule is used to indicate at least one path through which a data packet can pass; and sending the routing rule to a data bus, so that the data bus forwards, according to the routing rule, a received data packet to a service corresponding to the data packet. The service information of each service is dynamically obtained, so as to update a path indicated in a routing rule.
