The invention provides a transmission reconnection method, a device thereof, computer equipment and a storage medium. The transmission reconnection method comprises the steps of when a communication connection abnormity to a communication opposite-end is detected, re-establishing connection with the communication opposite-end; after the connection is re-established, exchange an identity token withthe communication opposite-end by means of a secret key which is exchanged in first communication with the communication opposite-end; verifying the identity of the communication opposite-end according to the identity token which is exchanged with the communication opposite-end, and furthermore after successful identity verification, continuing a transmission process before the communication connection abnormity. According to the transmission reconnection method, the device thereof, the computer equipment and the storage medium, on the condition that transmission continuity is required, not only can network reconnection be performed automatically, but also a fact that the reconnected opposite-end is the opposite-end before reconnection, thereby ensuring high stability and high safety in network connection.
