Abstract
The present disclosure discloses an information transmission method, user equipment, an access network device, and a core network device. The method includes: determining, by user equipment UE when the UE is in an idle state, whether there is to-be-transmitted uplink information; and sending, by the UE, a first request message to a first access network device when the UE determines that there is to-be-transmitted uplink information, where the first request message is a first air interface message for the UE to switch from the idle state to a connected state, and the first request message carries uplink non-access stratum NAS information and air interface identity information that is stored on the UE.
