1. A method comprising:
- receiving, by a first wireless access network node, feedback information from a second wireless access network node that performs data offload for the first wireless access network node, the feedback information relating to a buffer condition of a data buffer in the second wireless access network node, and the feedback information comprising a radio bearer identifier identifying a radio bearer associated with data stored in the data buffer;
in response to the feedback information, performing, by the first wireless access network node, control of the data offload for the radio bearer identified by the radio bearer identifier in the feedback information, the controlling comprising pausing communication of offloaded data associated with the data offload for the radio bearer from the first wireless access network node to the second wireless access network node;
in response to the pausing of communication of offloaded data associated with the data offload for the radio bearer, starting a timer at the first wireless access network node; and
in response to expiration of the timer, transfer, by the first wireless access network node, the radio bearer from the second wireless access network node to a third wireless access network node.

Abstract
A first wireless access network node receives feedback information from a second wireless access network node that performs data offload for the first wireless access node. The feedback information relates to one or more of a radio resource usage, a buffer condition, a hardware resource usage or a link quality. In response to the feedback information, the first wireless access network node performs control of the data offload.

15. 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, wherein the feedback information is sent in response to at least one criterion being satisfied, the feedback information relating to a buffer condition of the data buffer and comprising a radio bearer identifier identifying a radio bearer associated with data stored in the data buffer, wherein the at least one criterion relates to a threshold associated with usage of the data buffer, the feedback information to cause the second wireless access network node to control the data offload for the radio bearer identified by the radio bearer identifier in the feedback information, the controlling comprising pausing communication of offloaded data associated with the data offload for the radio bearer from the second wireless access network node to the first wireless access network node; after the pausing of communication of offloaded data associated with the data offload for the radio bearer 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 radio bearer from the second wireless access network node. - View Dependent Claims (16, 17, 18)

19. A first wireless access network node comprising:
-
at least one processor; and a non-transitory storage medium storing instructions executable on the at least one processor to; receive feedback information from a second wireless access network node that performs data offload for the first wireless access network node, the feedback information relating to a buffer condition of a data buffer in the second wireless access network node, and the feedback information comprising a radio bearer identifier identifying a radio bearer associated with data stored in the data buffer; in response to the feedback information, perform control of the data offload for the radio bearer identified by the radio bearer identifier in the feedback information, the controlling comprising pausing communication of offloaded data associated with the data offload for the radio bearer from the first wireless access network node to the second wireless access network node; in response to the pausing of communication of offloaded data associated with the data offload for the radio bearer, start a timer at the first wireless access network node; and in response to expiration of the timer, transfer the radio bearer from the second wireless access network node to a third wireless access network node. - View Dependent Claims (20)
