Abstract

The embodiment of the invention discloses a communication method, device and system. The communication method includes that the terminal device receives the context identifier sent by the second radio access network device and sends a first message including the context identifier to the first radio access network device, and the core network device receives the first message sent by the first radio access network device and send a message including the context identifier to the second radio access network device, the core network device receives the context information of the terminal device sent by the second radio access network device and sends The context information is sent to the first radio access network device. Therefore, communication between the first radio access network device and the second radio access network device is ensured, and work efficiency is improved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a communication method, device and system in a wireless network. Background technique [0002] A third generation partnership project (3rd Generation Partnership Project, 3GPP) standard is discussing a light connection (Light Connection) technology. The terminal device may enter the light connection state under the instruction of a radio access network (Residential Access Network, RAN) device, and the radio access network device is called an anchor radio access network device. The lightly connected state is a state between a radio resource control (Radio Resource Control, RRC) connected state and an idle (Idle) state. [0003] The terminal device that enters the lightly connected state from the RRC connected state obtains the context identifier allocated by the anchor radio access network device. Both the terminal device and the anchor radio access network device sto...
