Abstract: This application provides an information transmission method and an apparatus. A core network device obtains second public land mobile network (PLMN) information of a second cell before a cell handover of a terminal device. After the terminal device is handed over to a first cell, the core network device obtains first PLMN information of the first cell. When a second PLMN does not belong to a PLMN list and a first PLMN belongs to the PLMN list, the core network device sends first information to a first access network device corresponding to the first cell, where the first information includes the PLMN list, and the PLMN list includes a PLMN set that allows the terminal device to perform minimization of drive test.
