Abstract: A method includes a first access network device that sends first indication information to a second access network device. The first indication information indicates information about a current active BWP and/or transmission rate information of a terminal device on the first access network device. The second access network device determines information about a first-time active BWP and/or BWP configuration information of the terminal device on the second access network device based on the first indication information. The method may be used to enable the second access network device to determine the appropriate information about the first-time active BWP and/or the appropriate BWP configuration information of the terminal device on the second access network device. In this way, service interruption caused by switching of an active BWP is reduced, and/or service interruption caused by changing of a BWP configuration is reduced.
