This application provides a data transmission method, a base station, a local breakout controller, a gateway, and a system. The data transmission method includes: receiving, by a base station, LBO service data sent by user equipment, where the LBO service data carries information about an IP address of a first server; receiving, by the base station, a first message sent by an LBO controller, where the first message includes information about a correspondence between the IP address of the first server and an IP address of a gateway, and the gateway is a gateway that forwards the LBO service data to the first server; and sending, by the base station, the LBO service data to the gateway. According to the method, an LBO service can be performed without performing an additional configuration for the UE, so that a problem that the LBO service cannot be performed because the user equipment does not support a configuration of a plurality of APNs is resolved, thereby flexibly deploying the LBO service without changing the existing 3GPP standard protocol. In addition, compared with costs of upgrading and reconstructing a central gateway CGW to support the LBO service and forward local traffic in the prior art, CGW deployment costs are reduced.
