When a terminal device accesses or camps on a first cell served by a second network device, the terminal device records and stores first information of the terminal device in the first cell, where the first information may include connection failure report information of a radio link failure (RLF) or a handover failure, and/or measurement information obtained by performing measurement by using a minimization of drive tests (MDT) technology. After accessing a second cell, the terminal device may send, through the second cell, the first information to a first network device to which the second cell belongs, and a RAT corresponding to the second cell is different from a RAT corresponding to the first cell. ## Claims ### Claim at position 1 1-34.
