The terminal device receives configuration information sent by a network device, the configuration information being used for indicating one or more conditions for the terminal device to report random access-related information. The terminal device sends a successful handover report that does not contain the random access-related information to the network device in response to a random access of the terminal device not satisfying the one or more conditions for reporting the random access-related information. ## Claims ### Claim 1 A method of wireless communication, comprising: receiving, by a terminal device, configuration information sent by a network device, the configuration information being used to indicate one or more conditions for reporting random access-related information to the network device; and in response to a random access of the terminal device not satisfying the one or more conditions for reporting the random access-related information, sending, by the terminal device, a successful handover report that does not contain the random access-related information to the network device, wherein the one or more conditions for the terminal device to report the random access-related information further includes that a delay of a procedure of the random access of the terminal device exceeds a delay threshold. ### Claim 2 (depends on 1) The method of claim 1, further comprising: in response to the random access of the terminal device satisfying at least one of the one or more conditions for reporting the random access-related information, sending, by the terminal device, a successful handover report containing the random access-related information to the network device. ### Claim 3 (depends on 1) The method of claim 1, wherein the one or more conditions for the terminal device to report the random access-related information includes that a duration for the terminal device to access a target network exceeds a duration threshold. ### Claim 4 (depends on 3) The method of claim 3, wherein: the duration threshold is a pre-configured value for the terminal device, or the duration threshold is configured according to a signaling or a broadcast sent by the network device. ### Claim 5 (depends on 1) The method of claim 1, wherein: the delay threshold is a pre-configured value for the terminal device, or the delay threshold is configured according to a signaling or a broadcast sent by the network device. ### Claim 6 (depends on 1) The method of claim 1, wherein: a start time of the procedure of the random access is a time when the terminal device receives a signaling containing mobility control information or when the terminal device sends a message 1 for the random access, and an ending time of the procedure of the random access is a time when the terminal device successfully completes the random access. ### Claim 7 A terminal device, comprising: a processor; and memory storing instructions, which when executed by a processor, cause the processor to: receive configuration information sent by a network device, the configuration information being used to indicate one or more conditions for the terminal device to report random access-related information;
