SYSTEM FRAME NUMBER SYNCHRONIZATION METHOD AND RELATED APPARATUS

Embodiments of this application disclose a system frame number synchronization method, applied to a communication system defined in the enhanced common public radio interface eCPRI protocol. The communication system includes radio equipment control and radio equipment. The method includes: The radio equipment control generates system frame information, where the system frame information indicates a system frame number; and the radio equipment control sends the system frame information to the radio equipment by using a control plane message. A system frame number used by the radio equipment is consistent with the system frame number used by the radio equipment control, to ensure that the radio equipment can successfully parse a data packet from the radio equipment control, avoid service interruption, and improve reliability of the communication system.
