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.
Claims18
A method for managing context of one or more terminals by a first core network device, the method comprising:
- storing, by the first core network device, group information corresponding to a terminal and an associated context of the terminal;
- and
- establishing, by the first core network device, a correspondence between the terminal and the group information such that the first core network device is free from storing the associated context of the terminal.
A method for managing context of one or more terminals by a first core network device, the method comprising:
- in response to determining that the first core network device does not store group information corresponding to a terminal and an associated context of the terminal, obtaining, by the first core network device, the group information corresponding to the terminal and the associated context;
- and
- creating, by the first core network device, a group context based on the obtained group information, wherein the group context comprises the group information and includes context information for each of a group of terminals including said terminal.
A context management apparatus operating as a first core network device, comprising:
- a processing unit configured to:
- store group information corresponding to a first terminal and an associated context of the first terminal, and
- establish a correspondence between the first terminal and the group information such that the first core network device is free from storing the associated context of the first terminal.
