Network node and method related to buffer estimation

摘要

The present invention relates to a network node such as a base station for a wireless communications system, and to a method for supporting a change of a buffer estimation state of a user equipment from a passive to a proactive state. The method comprises receiving (410) information describing a buffer status of the user equipment, and determining (420) whether to change the buffer estimation state of the user equipment to the proactive state based on the received information. The purpose is to achieve a more correct UE buffer estimation state and thus better accuracy for the buffer estimation.

主权项

1. A method in a network node of a wireless communications system for supporting a change of a buffer estimation state of a user equipment from a passive to a proactive state, the method comprising:
receiving information describing a buffer status of the user equipment, the received information comprising a segment of a data unit and a buffer status report comprising a buffer content size for the user equipment; and determining whether to change the buffer estimation state of the user equipment to the proactive state based on the received information, wherein said determining comprises:
determining a sum of a size of the segment of the data unit and a size of previously received segments of the data unit, andchanging to the proactive state if the determined sum added to the buffer content size exceeds a first threshold.
