The embodiment of the invention provides a message retransmission method and apparatus. The method comprises: a sending terminal sends a first message to a receiving terminal through a first channel, wherein the first channel is a channel in transmission control protocol (TCP) data connection; a response message is received through a second channel, wherein the response message is used for indicating that the receiving terminal does not receive the first message, and the response message includes an indication field for indicating message transmission at the second channel; and the first message is transmitted to the receiving terminal through the second channel again, wherein the re-transmitted first message includes the indication field.
