A message scheduling method and device

Abstract

The invention relates to a message dispatching method and a device. In an embodiment of the invention, the method determines a length information for allowing dispatching data; acquiring a length information of a pending dispatching message queue; comparing the length information of the pending dispatching message queue with the length information for allowing dispatching data; if the length information of the pending dispatching message queue is smaller than or equal to the length information for allowing dispatching data, dispatching the pending dispatching message; if the length information of the pending dispatching message queue is larger than the length information for allowing dispatching data, acquiring a length information of a pending dispatching message in turn to be compared with length information for allowing dispatching data, and when the acquired length information accumulated value of the pending dispatching message is larger than the length information for allowing dispatching data, banding and dispatching the pending dispatching message. The invention can perform a self-adapting banding and dispatching treatment for the pending dispatching message smartly, increases the bandwidth availability of an air interface and network transmission efficiency in wireless transmission.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a message scheduling method and device. Background technique [0002] In the wireless broadband access technology of the wireless communication network, the media access control (MAC) layer defines a relatively complete quality of service (QoS) mechanism. The MAC layer sets different QoS parameters for each connection, including technical indicators such as rate and delay. Under the limitation of technical indicators, there are specific constraints on the amount of data that can be sent by each connection within a certain period of time. Therefore, for each connection, each scheduling opportunity can only send a certain amount of data packets. [0003] Since the size of the data packet is not exactly the same as the amount of data allowed to be sent for each scheduling opportunity of each connection, it may be larger or smaller than the amount of data all...

Problems solved by technology

[0007] This fixed-length fragmentation scheduling method has many disadvantages. First, because the fragmentation header is introduced to control the fragmentation of the message when fragmenting the message, the length of the fragmentation is small, resulting in a large number of fragments. When there are more, it will greatly increase the overhead of the fragmented header, making the transmission efficiency lower

[0008] Secondly, if the fixed length of the fragment is large, the data cannot be scheduled for the scheduling request whose length is smaller than the length of the fragment.

For example: All packets are fragmented into j-byte data fragments, but a certain scheduling request needs to schedule k (k<j) bytes of data. As a result, data cannot be scheduled for this scheduling. The opportunity is wasted, thus wasting the bandwidth resources of the air interface

[0009] In actual transmission, the data length of each scheduling is constantly changing according to the actual situation, and the length of the message will not be fixed, which determines that the method of fixed-length fragment scheduling cannot make full use of the precious Air interface bandwidth resources lead to low transmission efficiency
