Patent ID: 8654757

Claim:
A method for synchronization scheduling, comprising: obtaining, by lower layer network element(s), multiple synchronization sequences of a designated service from an upper layer network element to which the lower layer network element(s) belongs, wherein the upper layer network element processes data packets of the designated service according to a synchronization sequence length, and transmits the multiple synchronization sequences to the lower layer network element(s), wherein the synchronization sequences are a set of data packets with the same timestamp information; determining, by the lower layer network element(s), a scheduling transmission time interval according to the synchronization sequence length and a time division multiplexing period of the designated service, wherein the scheduling transmission time interval is a common multiple of the time division multiplexing period and the synchronization sequence length, and the time division multiplexing period of the designated service is 1/n time of the period of a wireless interface connection frame number, n is an integer; and transmitting, by the lower layer network element(s), a synchronization sequence, whose timestamp locates in a current scheduling transmission time interval, in an available transmission period of a designated scheduling transmission time interval.
