Data forwarding method, base station and relay station

The invention discloses a data forwarding method, a base station and a relay station. The data forwarding method comprises the following steps of: receiving a switch command message sent by a mobility management entity, wherein a user device identification is carried in the switch command message; establishing a forwarding data channel corresponding to the user device identification; sending a connection re-distribution message to the relay station, wherein a channel identification corresponding to the forwarding data channel is carried in the connection re-distribution message so that the relay station is beneficial to sending a data packet of a user device through the forwarding data channel corresponding to the channel identification; receiving the data packet sent by the relay stationand sending the data packet to the target base station. The data forwarding method provided by the embodiment of the invention can be used in a relay scene so as to realize lossless switch of the user device from the relay station to the target base station, thereby improving the service quality of a communication system in the relay scene.
