Based on above-mentioned mobile terminal hardware configuration, the preferred embodiment of data transmission device of the present invention is proposed.
Referring to Fig. 2, in the preferred embodiment of data transmission device of the present invention, which includes:
Module 10 is obtained, for obtaining the data transmission capabilities and channel quality of each data channel；
Diverter module 20, for based on each data channel data transmission capabilities and channel quality calculate each data channel
Transmittability, and each transmittability based on calculating is that each data channel distributes shunt ratio；
Transmission module 30, for judging whether the type of data to be transmitted business is pre- when available for transmission data service
If type of service is, data to be transmitted traffic assignments are transmitted to each data channel according to shunt ratio, it otherwise will be to
Transmitting data service is distributed to default data channel and is transmitted.
It should be noted that data transmission device proposed by the present invention is based on running of mobile terminal.
Requirement due to different types of service to mobile terminal or network data transmission ability is different, for example, to be passed
Transmission of data business is the small documents of text type, then It is not necessary to shunt to the data to be transmitted business, because of server
It requires to generate data distribution certain expense with terminal.These expenses include that server is needed business datum according to certain
Algorithm separates business datum, and mobile terminal needs to merge business datum using these algorithms, while mobile terminal also needs
Handle the mistake etc. on multiple data channel.Therefore, it is presently believed that for small documents such as texts, does not need to shunt.And for
Big file, such as picture, video etc., the data volume generally required are larger.At this time in order to promote rate, need to divide data
Stream.
Based on foregoing description, data service distribution is simplified to following algorithm by the present embodiment:
If mobile terminal opens n data channel at this time, for example, mobile terminal opens WCDMA (Wideband simultaneously
Code Division Multiple Access, wideband code division multiple access) data channel and LTE (Long Term Evolution,
Long term evolution) data channel.
For the data transmission capabilities for inquiring network, obtains module 10 and the network in each data channel is needed to issue request
Information requests the data transmission capabilities of the network.Assuming that the data transmission capabilities of corresponding network are respectively in each data channel
C1,C2,…,Cn。
Meanwhile obtaining module 10 and needing to measure the channel quality of each data channel corresponding network at this time, it is assumed that surveys at this time
The channel quality of amount is q1, q2 respectively ..., qn.Since the channel quality of heterogeneous networks measurement may have different measurements, such as
In wcdma, we usually use RSCP (Received Signal Code Power, received signal code power), lead in LTE
Common RSRP (Reference Signal Receiving Power, Reference Signal Received Power), and these values are largely
Negative value, that is, be worth bigger, and channel is worse instead.Therefore we take the inverse of the above parameter, that is, think the signal quality measured point
Not Wei 1/q1,1/q2 ..., 1/qn.
Then defining the transmittability of network at this time is respectively C1*1/q1, C2*1/q2 ..., Cn*1/qn.
To consider different types of service, need that tag is marked to different types of service, by the tag of text type
Labeled as 0, the tag of the types such as multimedia, picture is labeled as 1.
The data service ratio that diverter module 20 distributes in each data channel is as follows:
δ >=1 in above formula.In above formula expression, if tag=0, that is, what is transmitted is small documents, then transmission module 30 selects
Default data channel transfer.If tag=1, that is, the file transmitted is larger, then transmission module 30 is pressed in each data channel
According to the ratio of network capacity, data service is distributed.Wherein it can according to need setting in δ, i.e., in best data channel
On can distribute more data services.
Meanwhile diverter module 20 selects the maximum data channel x of transmittability in each data channel, x=max { C1*1/
Q1 ..., Cx*1/qx ..., Cn*1/qn }, it is maximum that current default data channel is updated to transmittability in each data channel
Data channel x.
To realize above data method for distributing business, need that corresponding data transmission device is arranged in server and terminal.
Wherein, the data transmission device major function of terminal side is as follows:
(1) mobile terminal is periodically collected to the measurement result of each data channel corresponding network, and is recorded；
(2) it periodically to the network challenge network data transmission ability, and records；
(3) transmittability of each data channel can be calculated, and calculates shunt ratio, and periodically by shunt ratio
It is sent to the data transmission device of server；
(4) judge type of service, can judge that the file that will be transmitted at present is what kind of file；
(5) it according to type of service, is shunted.I.e. if the tag=0 of type of service, default data channel is selected to send out
Send or receive data.If the tag=1 of type of service, is shunted according to shunt ratio.
The major function of the data transmission device of server side is as follows:
(1) the data distribution ratio that terminal side reports can be received；
(2) judge type of service, can judge that the file that will be transmitted at present is what kind of file；
(3) it according to type of service, is shunted.I.e. if the tag=0 of type of service, default data channel is selected to send out
Send or receive data.If the tag=1 of type of service, is shunted according to shunt ratio.
Specifically, diverter module 20 is after distributing shunt ratio for each data channel, by transmission module 30 by each number
Server is sent to according to the shunt ratio in channel.
In the present embodiment, shunt ratio is assigned in each data channel and receives the data to be transmitted of pre-set business type
When business, transmission module 30 is led to according to the corresponding shunt ratio of each data channel, by data to be transmitted traffic assignments to each data
It is transmitted in road.Since data to be transmitted business includes data service to be received and data service to be sent, transmission module 30 exists
Different according to the transport-type of data to be transmitted business when carrying out the shunting transmission of business to be transmitted, specific transmission operation is
It is different.
Specifically, when the data to be transmitted business of the received pre-set business type of mobile terminal is data service to be sent
When, transmission module 30 sends data to be transmitted traffic assignments to each data channel according to each shunt ratio, to be sent to
The server, for example, mobile terminal currently opens LTE data channel, WCDMA data channel and Wi-Fi data channel, and
The shunt ratio of aforementioned each data channel is followed successively by 30%, 20% and 50%, is receiving the number to be transmitted that data volume is 100M
When according to business, the data of 30M in data to be transmitted business are assigned to LTE data channel and sent by transmission module 30, will be to
The data of 20M are assigned to WCDMA data channel and are sent in transmitting data service, by the number of 50M in data to be transmitted business
It is sent according to Wi-Fi data channel is assigned to, correspondingly, to merge it received to be transmitted from aforementioned each data channel for server
Data service.
When the data to be transmitted business of the received pre-set business type of mobile terminal is data service to be received, mould is transmitted
Block 30 receives the data to be transmitted business that server is sent according to each shunt ratio by each data channel.For example, diverter module
The shunt ratio of 20 LTE data channel, WCDMA data channel and the Wi-Fi data channel reported is respectively 30%, 20% and
50%, in the data to be transmitted business for having 100M, the data of 30M in data to be transmitted business are assigned to LTE number by server
It is sent according to channel, the data of 20M in data to be transmitted business is assigned to WCDMA data channel and are sent, it will be to be passed
The data of 50M are assigned to Wi-Fi data channel and are sent in transmission of data business, correspondingly, transmission module 30 merges its past
State the received data to be transmitted business of each data channel.
Further, in the present embodiment, which further includes correction module, for passing in transmission module 30
During defeated data to be transmitted business, obtain and the packet loss based on each data channel to the shunt ratio of each data channel into
Row amendment.
It should be noted that network environment is ever-changing, and carrier network is usually that user provides internet
Access service, mobile terminal need carrier network via the Internet transmission to destination server after issuing data, and data exist
Transmission between carrier network and internet is influenced by various factors, in the present embodiment, describes data using packet loss
By being influenced in transmission process.
In the present embodiment, when transmission module 30 transmits data to be transmitted business, correction module loses each data channel
Packet rate is counted, and the packet loss of each data channel of statistics is compared with default packet loss, is repaired according to comparison result
The shunt ratio of just each data channel.Specifically, " when the packet loss of data channel is greater than default packet loss, to reduce the number
According to the shunt ratio in channel；When the packet loss of data channel is less than default packet loss, increase the shunt ratio of the data channel "
For purport, it is to limit with " shunt ratio of each data channel adjusted and value for 1 ", carries out the amendment of shunt ratio.It is logical
It crosses and the shunt ratio of each data channel is corrected in real time, influenced to avoid network fluctuation on caused by data transmission.
The data transmission device that the present embodiment proposes is applied to mobile terminal, by comprehensively considering each data of mobile terminal
The data transmission capabilities and channel quality in channel, to the transmittability of each data channel of quantificational description, and according to number to be transmitted
According to the type of service of business, shunting screening is carried out.When needing to shunt, by data to be transmitted traffic assignments to each data channel into
Row transmission, makes full use of the transmittability of each data channel, when not needing to shunt, by data to be transmitted traffic assignments to default
Data channel is transmitted.The present invention can greatly improve the message transmission rate of mobile terminal.
Further, the present invention also provides a kind of data transmission methods, in conjunction with reference Fig. 2 and Fig. 3, in data of the present invention
In the preferred embodiment of transmission method, which includes:
Step S10 obtains the data transmission capabilities and channel quality of each data channel；
Step S20, data transmission capabilities and channel quality based on each data channel calculate the transmission energy of each data channel
Power, and each transmittability based on calculating is that each data channel distributes shunt ratio；
Step S30 judges whether the type of data to be transmitted business is pre-set business class when available for transmission data service
Type is transmitted data to be transmitted traffic assignments to each data channel according to shunt ratio, otherwise by data to be transmitted
It is transmitted in traffic assignments to default data channel.
It should be noted that the data transmission device of data transmission method provided by the invention as shown in Figure 2 executes, this is defeated
Data transmission device is based on running of mobile terminal.
Requirement due to different types of service to mobile terminal or network data transmission ability is different, for example, to be passed

The channel quality of amount is q1, q2 respectively ..., qn.Since the channel quality of heterogeneous networks measurement may have different measurements, such as
In wcdma, we usually use RSCP (Received Signal Code Power, received signal code power), lead in LTE
Common RSRP (Reference Signal Receiving Power, Reference Signal Received Power), and these values are largely
Negative value, that is, be worth bigger, and channel is worse instead.Therefore we take the inverse of the above parameter, that is, think the signal quality measured point
Not Wei 1/q1,1/q2 ..., 1/qn.
Then defining the transmittability of network at this time is respectively C1*1/q1, C2*1/q2 ..., Cn*1/qn.
To consider different types of service, need that tag is marked to different types of service, by the tag of text type
Labeled as 0, the tag of the types such as multimedia, picture is labeled as 1.
The data service ratio that diverter module 20 distributes in each data channel is as follows:
δ >=1 in above formula.In above formula expression, if tag=0, that is, what is transmitted is small documents, then transmission module 30 selects
Default data channel transfer.If tag=1, that is, the file transmitted is larger, then transmission module 30 is pressed in each data channel

It is sent to the data transmission device of server；
(4) judge type of service, can judge that the file that will be transmitted at present is what kind of file；
(5) it according to type of service, is shunted.I.e. if the tag=0 of type of service, default data channel is selected to send out
Send or receive data.If the tag=1 of type of service, is shunted according to shunt ratio.
The major function of the data transmission device of server side is as follows:
(1) the data distribution ratio that terminal side reports can be received；
(2) judge type of service, can judge that the file that will be transmitted at present is what kind of file；
(3) it according to type of service, is shunted.I.e. if the tag=0 of type of service, default data channel is selected to send out
Send or receive data.If the tag=1 of type of service, is shunted according to shunt ratio.
