the quality of the radio link between the terminal device and the first access network device is lower than a seventh threshold, and the value by which the quality of the radio link between the terminal device and the second access network device is higher than the quality of the radio link between the terminal device and the first access network device is greater than an eighth threshold.

For the foregoing aspects, in a possible design, the SRB configuration information includes SRB0 configuration information, or SRB0 configuration information and SRB1 configuration information, and an SRB type is a secondary cell group SCG bearer or a split bearer.

For the foregoing aspects, in a possible design, the first configuration information further includes random access configuration information, and the random access configuration information is used by the terminal device to initiate, to the second access network device, a random access process for RRC connection establishment.

For the foregoing aspects, in a possible design, the first configuration information further includes measurement configuration information, and the measurement configuration information is used by the terminal device to determine, based on a result obtained by performing measurement by using the measurement configuration information, whether the trigger condition is met.

According to a still further aspect, an embodiment of the present invention provides a computer readable storage medium, where a computer program is stored in the computer readable storage medium, and when the program is executed by a processor, steps of the method in the foregoing aspects are implemented.
