Abstract: This application provides a context management method and apparatus, to resolve a problem that contexts of a large quantity of terminals occupy a large amount of storage space of an AMF entity. The method includes: when a first core network device has stored group information corresponding to a terminal, establishing, by the first core network device, a correspondence between the terminal and the group information. This application relates to the field of communications technologies.

Abstract: An aircraft control method and an apparatus are provided, and pertain to the field of communications technologies. The method performed by an AMF network element includes: obtaining information about a no-fly zone of an aircraft (301); sending reference information to a control apparatus when a shortest distance between the aircraft and the no-fly zone is less than or equal to a first preset value (302), where the reference information includes at least one of first indication information and location information of the aircraft, and the first indication information indicates that the shortest distance between the aircraft and the no-fly zone is less than or equal to the first preset value. This resolves problems that efficiency of preventing an aircraft from flying in a no-fly zone is relatively low and an advance preparation process is relatively complex and time-consuming, avoids installation of geofences on an edge of the no-fly zone.
