Abstract

Embodiments of the present invention provide a data offloading method and a base station. The method includes: sending, by a master base station, a first request message to a mobility management control node, where the first request message includes an address of a local gateway of a secondary base station, and the first request message is used to request to perform data offloading at the local gateway of the secondary base station; receiving, by the master base station, a first response message that is sent by the mobility management control node according to the first request message, where the first response message includes a first related identifier ID of the local gateway of the secondary base station, and the first related ID is used to indicate a first bearer according to which data offloading is performed at the local gateway of the secondary base station.

Dependent claims

A base station, comprising:

a transmitter, configured to send a first request message to a mobility management control node, wherein the first request message comprises an address of a local gateway of a secondary base station, and the first request message is used to request to perform data offloading at the local gateway of the secondary base station;
a receiver, configured to receive a first response message that is sent by the mobility management control node according to the first request message sent by the first sending module, wherein the first response message comprises a first related identifier ID of the local gateway of the secondary base station, and the first related ID is used to indicate a first bearer according to which data offloading is performed at the local gateway of the secondary base station;
and
wherein the transmitter is further configured to send a second request message comprising the first related ID to the secondary base station according to the first response message received by the receiving module, to instruct the secondary base station to perform data offloading at the local gateway of the secondary base station according to the first bearer.
