Embodiment Construction

[0032] Aspects of the invention are described with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough explanation of the invention. It is evident, however, that the present invention may be practiced without observing these specific details.

[0033] figure 1 It is a flowchart of a method for scheduling data flow transmission through a shared communication link according to an embodiment of the present invention.

[0034] The method may be implemented in a communication node such as a base station, radio network controller (RNC), switch or router.

[0035] Such as figure 1 As shown, in block S10, for each data stream, for the next time slot (such as time slot T j ) to determine the first data volume of the data stream. The first data amount is in the next time slot of the next time slot (such as time slot T j+1 ) before the end of the data flow reaches the delay in the amount of data. The delay...

Abstract

A method and an apparatus for scheduling transmission of data streams over a common communication link are disclosed. The method includes the following steps:for each of the data streams, determining a first amount of data in the data stream for an incoming time slot; for each of the data streams, determining, based on an available data amount that is provided to the data streams for the incoming time slot and the first amounts of data in the data streams for the incoming time slot according to priority levels of the data streams, a second amount of data in the data stream; and transmitting, during the incoming time slot, the second amounts of data in the plurality of data streams over the common communication link according to the priority levels of the data streams.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for scheduling transmission of data streams through a shared communication link. Background technique [0002] One of the purposes of network convergence is to support multi-service traffic. The concept of converged networking has been around for decades, combining the transmission of voice, data and other signals into a single high-speed network interface. [0003] In a converged network, what is needed is a communication node (such as a base station, radio network controller (RNC), switch, or router) capable of transmitting multiple data streams with different latency requirements and different priorities over a shared communication link The data. [0004] Many solutions have been developed to handle the transmission of multiple data streams with different latency requirements and different priorities over a shared communication link. ...
