A MDT measurement log transmission method, a terminal, and a readable storage medium. The MDT measurement log transmission method comprises: transmitting an available indication to a network side via a first signaling bearer, the available indication being used to indicate to the network side that log-type MDT measurement log information has been stored; receiving a reporting indication message transmitted by the network side via a second signaling bearer, the reporting indication message being used to indicate that the log-type MDT measurement log information has been reported; and determining a third signaling bearer, and transmitting the log-type MDT measurement log information to the network side on the basis of third signaling. The solution reports a MDT measurement log via a MN link or a SN link, thereby reporting a MDT measurement result in a timely manner.
