Document Type and Number:
WIPO Patent Application WO/2021/164541
Kind Code:
A1
Abstract:
Provided are a communication device and a clock synchronization method. The communication device comprises a control board, a first cross board and a service board. When the control board is ready to be drawn away from the communication device, the first cross board and the service board may be notified by means of a first notification signal; and on the basis of the signal, the first cross board may maintain a second clock identical to a first clock generated by the control board, and the service board may be switched from the first clock to the second clock. After the control board is offline, a clock source is switched from the control board to the first cross board, and the first cross board and the service board both perform subsequent related services on the basis of the second clock so as to continuously and normally execute related service processing, so as to avoid service processing interruption.
