摘要：The present invention discloses a message acknowledgement method,apparatus, and system, where the method includes that: An access point sends a beaconframe, receives an uplink frame sent by a terminal, and sends an acknowledgement framefor the uplink frame, where the acknowledgement frame includes offset time, and theoffset time is a difference between a time point when the access point sends the

acknowledgement frame and a time point when the access point sends the beacon frame;and a terminal that receives the acknowledgement frame calculates a difference betweena time point when the terminal receives the acknowledgement frame and a time pointwhen the terminal lately receives a beacon frame, and because the difference is

consistent with offset time carried in an acknowledgement frame sent by an access pointassociated with the terminal, compares the difference that is obtained through

calculation by the terminal and is between the time point when the terminal receives theacknowledgement frame and the time point when the terminal lately receives a beaconframe with the offset time carried in the acknowledgement frame, and if a differencebetween the two is within a preset error range, determines that the acknowledgement

frame received by the terminal is sent by the access point associated with the terminal.
