A synchronization scheduling method, comprising:sending a plurality of data bursts of a specified service by an upper network element to specified network elements belonging to the upper network element, wherein data packets of the data bursts include time stamp information so that the specified network elements send the data bursts according to the time stamp information; and

setting difference between the time stamp information of every two adjacent data bursts by the upper network element to be an integer multiple of a Time Division Multiplex (TDM) period of the specified service, wherein length of the TDM period is one of exactly divided parts of a system frame number period of a radio interface.

The method of Claim 3, wherein the step of presetting the TDM period comprises:the upper network element configures the TDM period of the specified service and informs the specified network elements of the configured TDM period; or

the specified network elements configure the TDM period of the specified service and inform the upper network element of the configured TDM period; or

the upper network element configures the TDM period of all services.

The method of Claim 1, further comprising:when the time stamp information corresponds to an initial moment of a current TDM period, sending the data bursts to which the time stamp information corresponds by the specified network elements starting from an initial moment of available transmission time of the current TDM period after the upper network element sends a plurality of the data bursts; and

when the time stamp information does not correspond to the initial moment of the current TDM period, sending the data bursts to which the time stamp information corresponds by the specified network elements starting from the initial moment of the available transmission time of a TDM period next to the current TDM period after the upper network element sends a plurality of the data bursts.

The method of Claim 1, further comprising:when the time stamp information corresponds to an initial moment of available transmission time of a current TDM period, sending the data bursts to which the time stamp information corresponds by the specified network elements starting from an initial moment of the available transmission time of the current TDM period after the upper network element sends a plurality of the data bursts; or,

when the time stamp information does not correspond to the initial moment of the available transmission time of the TDM period, sending the data bursts to which the time stamp information corresponds by the specified network elements starting from the initial moment of the available transmission time of a TDM period next to the current TDM period after the upper network element sends a plurality of the data bursts.

10

A synchronization scheduling method, comprising:sending a plurality of data bursts of a specified service by an upper network element to specified network elements belonging to the upper network element, wherein data packets of the data bursts all include time stamp information so that the specified network elements send a plurality of the data bursts according to the time stamp information; and

setting difference between the time stamp information of every two adjacent data bursts by the upper network element to be one of exactly divided parts of a Time Division Multiplex (TDM) period of the specified service, wherein length of the TDM period is one of exactly divided parts of a system frame number period of a radio interface.
