Embodiment Construction

[0024] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] figure 1 It is a flowchart of an embodiment of the time division multiplexing service scheduling method of the present invention, such as figure 1 As shown, the time division multiplexing service scheduling method includes the following steps:

[0026] Step 101: Uniformly select time slots to be allocated from the effective time slots of the microwave frame, and correspondingly allocate the time slots to be allocated to each time division multiplexing service in the time division multiplexing service according to a set sequence.

[0027] Step 102, adjusting the rate of the time division multiplexing service after the time slot is allocated to be consistent with the rate of the microwave frame.

[0028] In the microwave frame of the microwave link, multiple time division multiplexing (TDM) services can be mappe...

Abstract

The embodiment of the invention relates to a method for dispatching time division multiplexing business and a device thereof, wherein the method comprises the steps: evenly selecting time slot to be allocated from the effective time slot of microwave frame, and correspondingly allocating the time slot to be allocated to the each route of the time division multiplexing business in the time divisionmultiplexing business according to set order; and adjusting the speed of the time division multiplexing business after allocating the time slot and the speed of the microwave frame to be accordant. The embodiment of the invention can evenly disperse the TDM business into the microwave frame of a microwave link, according to the bandwidth change of the microwave link, increase or reduce the TDM business on the microwave link, reduce the transferring jitter and the switching jitter of the TDM business, reduce the timelag of the TDM business, guarantee the service quality of the TDM business, and improve the utilization factor of the microwave link.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a time division multiplexing service scheduling method and device. Background technique [0002] Microwave transmission is greatly affected by the weather. When the weather is clear, the signal-to-noise ratio of the transmission channel is high, and higher modulation modes can be used on channels with the same channel spacing, such as 256 quadrature amplitude modulation (Quadrature Amplitude Modulation; referred to as: QAM), at this time the microwave link has a larger link bandwidth; on the contrary, when there is rain and snow, the signal-to-noise ratio of the transmission channel decreases, and only a lower modulation mode can be used on the channel with the same channel spacing, such as Quadrature Phase Shift Keying (Quadrature Phase Shift Keying; QPSK for short), at this time, the microwave link has only a small link bandwidth. When th...
