1. A first base station, comprising:
a transmitter, configured to send a first message to a second base station, wherein the first message requests to add a data radio bearer (DRB); and
a receiver, configured to receive a second message sent by the second base station, wherein the second message indicates an identifier of at least one DRB, wherein
the transmitter is further configured to send first information to user equipment, wherein the first information comprises DRB configuration information, and the DRB configuration information comprises the identifier of the at least one DRB,
wherein the first base station sends the first message after updating a DRB identifier, to generate the identifier of a currently available DRB, wherein a reason for updating the DRB identifier comprises at least one of adding a DRB or releasing a DRB,
wherein the first base station further comprises a processor, wherein the processor is configured to update the identifier of the available DRB, to generate the identifier of the currently available DRB, and
wherein the second message comprises any one or more of the following information:
the identifier of the currently available DRB;
an identifier of a DRB occupied the second base station;
an identifier of a DRB released by the second base station; or
a mapping relationship that is between a quality of service (QOS) flow and a DRB and that is configured by the second base station.
