Clock drift processing method, network element, and storage medium

A first network element, comprising:

• a processor, and a memory, the memory being configured to store computer-executable instructions, and the processor being configured to execute the computer-executable instructions to perform:
• receiving a first notification message transmitted by a second network element, the first notification message comprising a first clock difference, the first clock difference being a clock difference between a first clock domain and a second clock domain acquired by the second network element in a first time period, wherein:
• transmission of the first notification message by the second network element is triggered in response to a clock drift being greater than a drift amplitude value, the clock drift is a difference between a first value and a second value of the first clock difference in the first time period, the first clock domain is a clock domain of a data network (DN), the second clock domain is a clock domain of a wireless network, and the drift amplitude value is a maximum value of a change amplitude of a clock difference between the first clock domain and the 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.
