FIELD: radio engineering, communication.
SUBSTANCE: synchronisation scheduling method involves a lower layer network element obtaining multiple synchronisation sequences of a defined service from an upper layer network element with which the lower layer network element is associated. The upper layer network element processes data packets of the defined service according to a synchronisation sequence length, and transmits the multiple synchronisation sequences, which are a set of data packets with the same time stamp information, to the lower layer network element. The lower layer network element determines a transmission scheduling time interval according to the synchronisation sequence length and time division multiplexing period of the defined service. The transmission scheduling time interval is a common multiple of the time division multiplexing period and the synchronisation sequence length, and the time division multiplexing period of the defined service is 1/n of the period of a wireless interface connection frame number, where n is an integer; and as for the synchronisation sequence whose time stamp is set in the current transmission scheduling time interval, the lower layer network element transmits it in an available transmission period of a designated transmission scheduling time interval.
EFFECT: avoiding service data loss.
