Disclosed is an information transmission method. The method includes: a first network node establishes a common transmission channel with a second network node; the first network node receives uplink information sent by a terminal device, where the terminal device is in an inactive state and moves from a service area of the second network node to a service area of the first network node; the first network node sends, by means of the common transmission channel, the uplink information and identification information of the terminal device to the second network node; and the first network node receives, by means of the common transmission channel, a parsing result obtained from parsing the uplink information by the second network node. Also disclosed is an information transmission apparatus.
