A method for processing clock drift implemented by a first network element includes: receiving a first notification message transmitted by a second network element, the first notification message including a first clock difference between a first clock domain and a second clock domain acquired by the second network element, transmission of the first notification message being triggered by a clock drift between the first clock domain and the second clock domain being greater than a drift amplitude value, which is a maximum value of a change amplitude of a clock difference between the first and second clock domain; determining first time sensitive communication assistance information (TSCAI) according to the first clock difference; and transmitting the first TSCAI to a radio access network (RAN) device, the first TSCAI being used by the RAN device to perform time control on a data stream in the first clock domain.
