Abstract: This application provides a communication method and apparatus, so that a terminal device reports an RLF report related to whether link recovery for an MCG succeeds. The terminal device separately communicates with a first network device and a second network device, where the first network device manages a first MCG, the second network device manages a first SCG, and an MCG link recovery function is configured for the first SCG. After determining that a radio link failure RLF occurs in the first MCG, the terminal device sends a first RLF report to a third network device, where the first RLF report is related to whether link recovery for the first MCG succeeds.

Abstract: This application provides a random access report recording method and an apparatus, including: A terminal device initiates a random access process to a cell managed by a secondary base station, to obtain a first secondary base station random access report; and the terminal device records the first secondary base station random access report when a quantity of historical secondary base station random access reports recorded by the terminal device is less than a first threshold.

Abstract: A terminal device obtains a cell change cause indication. The cell change cause indication indicates that a first cell change of the terminal device from a source cell to a first target cell or a second cell change of the terminal device from the first target cell to a second target cell is associated with a communication service of the terminal device. The first target cell uses a first radio access technology, and the source cell and the second target cell use a second radio access technology different from the first radio access technology. The terminal device sends the cell change cause indication to a second target access network device that provides the second target cell.
