12. A communication apparatus, comprising:
one or more processors; and
a non-transitory computer readable medium storing a program to be executed by the one or more processors, wherein the program comprises instructions that when executed by the one or more processors, cause the communication apparatus to perform operations comprising:
determining a failure report, wherein the failure report comprises information about a cell in a secondary cell group (SCG) in which master cell group (MCG) connection recovery is attempted when the communication apparatus detects that a connection failure occurs in an MCG, and wherein the failure report further comprises information indicating a time elapsed between a SCG failure and a MCG failure, wherein the time elapsed between the SCG failure and the MCG failure is a time since the connection failure occurs in the MCG to a time point at which the terminal device detects, after the connection failure occurs in the MCG, that a second connection failure occurs in the SCG; and
sending the failure report to a first access network device.
