Embodiment 1

[0095] In this embodiment, there are 4 narrowband channels, all of which work normally: including 2 shortwave channels, the transmission rate is 120B / s, and the unsent data lengths are 10Byte and 50Byte respectively, which are respectively recorded as channel A and channel B; Ultrashort wave channel, the transmission rate is 960B / s, and the unsent data lengths are 50Byte and 100Byte respectively, which are recorded as channel C and channel D respectively. The serial number of the data packet to be sent is 1, the length is 200Byte, and the attribute data is 2Byte. The workflow is as follows:

[0096] Data sender:

[0097] Step 1: Judge the working status of each channel, and they all work normally.

[0098] Step 2: Sort each channel according to the load from light to heavy:

[0099] Channel 1 (C): The transmission rate is 960B / s, the length of the data to be sent is 50Byte, and the load is 0.052s.

[0100] Channel 2 (A): The transmission rate is 120B / s, the length of the d...

Embodiment 2

[0155] In this embodiment, there are 4 narrowband channels, all of which work normally: 2 shortwave channels with a transmission rate of 120B / s; 2 ultrashortwave channels with a transmission rate of 960B / s. There is a large data volume file to be transmitted, and the file is split into 200Byte data packets and transmitted sequentially. The dynamic allocation method is the same as that in Embodiment 1.

[0156] Effect of the present invention is illustrated by this embodiment:

[0157] Using the original backup method for transmission, calculate the transmission capacity:

[0158] If the shortwave channel is used, the number of data packets transmitted per second

[0159] If the ultrashort wave channel is used, the number of data packets transmitted per second

[0160] The method of the present invention dynamically allocates channels in real time, can make full use of the communication resources of multiple sets of narrowband communication equipment, and calculate the t...

Abstract

The invention discloses a channel binding transmission based multichannel dynamic allocation method in a narrow-band communication system. A data sending terminal is used for executing the follow procedures: selecting channels in normal communication; calculating the present load of each channel in normal communication and sorting the channels according to the loads of the channels in the order of from the lightest to heaviest; according to the length of the present data to be sent, analyzing the channels in the sort order; calculating the number of the channels for binding transmission and determining the channels for binding transmission; according to the present loads of the determined channels for binding transmission and on the premise that the sending time of the present data packet is shortest, calculating the length of data segment allotted to each channel; according to the computed result, dividing the present data packet to obtain a group of data segments, packing the data segments, and allotting each packed data segment to the designated channel for binding transmission. The data receiving end is used for executing the follow procedures: receiving the data segment sent from each channel; analyzing the information of each data segment; recovering the data segments subjected to binding transmission into the whole data.

Description

technical field [0001] The invention relates to a multi-channel dynamic allocation method, in particular to a multi-channel dynamic allocation method applied in a narrowband communication system. Background technique [0002] In the communication system, data transmission requires a set of communication means with high reliability, large data volume and low delay data transmission. However, in many cases, communication cannot be transmitted through wired channels, and can only rely on short-wave / ultrashort wave and other narrowband wireless channels, which have the characteristics of strong autonomy, long communication distance, and not easy to be destroyed or damaged, are widely used in various communication systems, especially in systems that require high reliability. [0003] At present, there are the following problems in the use of narrowband data transmission in China, which restricts its application in data transmission. [0004] A. In many cases, the real-time data...
