Abstract
Provided are an information transmission method and a device. The method includes receiving, by a first core network element, a first message. The first message is used to notify the first core network element that a N3GPP access is unavailable or that a terminal is in an idle state over the N3GPP access. If there is downlink data arriving at the first core network element, the method further includes transmitting, by the first core network element, the downlink data via a 3GPP access, discarding the downlink data, or delaying transmission of the downlink data.
