Abstract
The present disclosure relates to information sending methods, and first access network devices and systems. One example system includes a first access network device and a core network device, and a connection for a terminal exists between the first access network device and the core network device. One example method includes determining that context information of the terminal is to be obtained, obtaining the context information of the terminal from the core network device. When determining that the context information of the terminal is to be obtained, the first access network device requests the context information from the core network device without storing the context information in advance.
