Controlling data offload in response to feedback information

A first wireless access network node comprising:

• a data buffer,
• a communication interface to communicate with a second wireless access network node, and
• at least one processor configured to:
• send, for receipt by the second wireless access network node, feedback information related to data offload from the second wireless access network node to the first wireless access network node, the feedback information identifying a user equipment (UE) and including information relating to a buffer condition of the data buffer, the feedback information to cause the second wireless access network node to control the data offload for the UE identified by the feedback information, wherein the control of the data offload comprises pausing communication of offloaded data associated with the data offload for the UE from the second wireless access network node to the first wireless access network node,
• receive, from the first wireless access network node, offloaded data of at least one radio bearer for the UE, based on the control of the data offload performed by the second wireless access network node,
• after the pausing of communication of offloaded data associated with the data offload for the UE from the second wireless access network node to the first wireless access network node:
• send further feedback information to the second wireless access network node;
• and
• responsive to the further feedback information, resume receiving communication of offloaded data associated with the data offload for the UE from the second wireless access network node.

A first wireless access network node comprising:

• a data buffer;
• a communication interface to communicate with a second wireless access network node;
• and
• at least one processor configured to:
• receive feedback information from the second wireless access network node that performs data offload for the first wireless access node, the feedback information identifying a user equipment (UE) and including information relating to a buffer condition of a data buffer in the second wireless access network node;
• in response to the feedback information, perform control of the data offload that includes controlling an offload of at least one radio bearer of the UE identified by the feedback information, the controlling of the offload of the at least one radio bearer of the UE by the at least one processor of the first wireless access network node comprising pausing communication of offloaded data associated with the data offload for the UE from the first wireless access network node to the second wireless access network;
• and
• after the pausing of communication of offloaded data associated with the data offload for the UE from the first wireless access network node to the second wireless access network node:
• receive further feedback information from the second wireless access network node;
• and
• responsive to the further feedback information, resume communication of offloaded data associated with the data offload for the UE from the first wireless access network node to the second wireless access network node.
