摘要：Disclosed are a method, a device and a system for reducing confirmation packets at a transmission control layer, which relate to the field of communications, and solve the problem that confirmation packets sent by a receiving end in wireless communication occupy a lot of air interface resources and cause interference for other communication data. The solution provided by the present invention comprises: receiving a data packet and a sending end checksum sent by a sending end, wherein the sending end checksum is generated by the sending end according to the data packet; generating a receiving end checksum according to the received data packet; transmitting the data packet to a transmission control layer of the receiving end when it is determined that the sending end checksum is the same as the receiving end checksum; returning a data reception acknowledgment to the sending end; when a transmission control layer acknowledgment packet sent by the transmission control layer of the receiving end is received, discarding the transmission control layer acknowledgment packet. The present invention is mainly applicable to network communications systems.
