<p>Disclosed are a method, device and system for data transmission. The method for data transmission includes: a first network side device receives downlink service data from the core network, wherein the first network side device uses a first access technology (S102); the first network side device is associated with a second network side device using a second access technology to send the downlink service data to a User Equipment (UE) (S104). The adoption of the invention can solve the problem that insufficient capacity of a single system may occur in existing network deployment, which limits the throughput of the user terminal, and the problem that load balance among systems can only be implemented through handover or redirection, which causes waste of resources.</p> |
