Based on above-mentioned terminal 100 and the network architecture, the embodiment of the present invention provides a kind of data transmission method. The transfer of the embodiment of the present invention is based on link, namely when there being data service to need transmission, setting up one or more (two or more) link, each link is for transmitting a certain size data packet, thus completes the transmission of whole data.
See Fig. 4, the data transmission method of the embodiment of the present invention comprises:
The connection of step S1, the in real time each interface of detection.
It will be understood that namely the connection of detection interface is whether data detection channel is connected. Such as, namely the connection of detection WIFI interface is detect whether to be linked into WIFI network by WIFI data channel and carry out data transmission.
In an embodiment of the present invention, interface comprises WIFI interface, LTE interface, 3G interface etc. And the number of interface can be multiple, such as, interface can comprise two LTE interfaces and two WIFI interface.
In an embodiment, see Fig. 5, interface detection of connectivity carries out in such a way:

Wait that the 2nd presets the time (such as, 10 seconds), if not receiving reply, then this interface being labeled as and be not connected (down), if receiving reply, then this interface being labeled as connection (UP).
In certain embodiments, if before interface being connected state, waiting that preset duration does not receive reply, then this interface being labeled as and be not connected. If before interface being non-connected state, waiting that preset duration receives reply, then thinking that this link is connected, this interface is labeled as connection.
Concrete, if a certain interface is for being connected (UP) state, then this interface can be added in available interface list; If a certain interface is not for be connected (down), then do not added to and deleted from available interface list in available interface list or by it.
It will be understood that the connection of interface is also undertaken by other mode, such as, the modes such as empty data packet are sent.
Step S2, when data service having been detected, set up at least one link.
Establish the link and refer to and establish the link between terminal 100 and other terminal or server, such as, shaken hands by three times and establish the link. The quantity of link can set according to practical situation, such as, and the data volume size etc. of the supported maximum link number of terminal 100, data service.
S3, according to shunting weight, the link of foundation is assigned to the interface being in connected state to carry out the transmission of data service.
In an embodiment of the present invention, the shunting weight that weight comprises 1:1 and shunts weight and obtain according to interface speed and time-delay calculation is shunted.
Concrete, in an embodiment of the present invention, an initial route rule can be set up according to the connection of interface. This initial route rule can be set up according to the mode divided equally, namely according to the shunting weight of 1:1 so that the link number to be transmitted of the interface assignment being in connected state is identical. Such as, if there being three interfaces to be in connected state, the maximum link number that terminal 100 can be set up is 9, then initial route rule is that the 1st, 2 and 3 article of link is by the first interface transmission, 4th, 5 and 6 articles of links are by the 2nd interface transmission, and the 7th, 8 and 9 article of link is by the 3rd interface transmission. Thus, in embodiments of the invention, when transmitting data, first carry out the transmission of data according to initial route rule.
In the transmitting procedure of data, adjust the shunting weight of each interface according to the speed of interface and time delay. Concrete, such as, preset time (such as, 1 second) docking port every one first and test the speed, preset the time (5 seconds) according to speed corresponding to interface and time-delay calculation shunting weight every one the 2nd. In certain embodiments, it is also possible to only do not consider time delay according to the real time rate calculating shunting weight of interface.
In an embodiment of the present invention, the rate detection of interface is carried out in such a way:
Every default time (such as, 1 second), obtain the present rate of change as interface of interface byte number. Concrete, if first time detects the speed of a certain interface, then the byte number that detection obtains is preserved. If not first time detects the speed of a certain interface, then the interface byte number once acquired before being subtracted by the interface byte number acquired, the difference obtained is the present rate of this interface again divided by time of twice detection.
In an embodiment of the present invention, according to the speed of interface and time-delay calculation shunting weight in the following ways:
Docking port tests the speed, and detect whether interface is in congested state, if, whether than the maximum rate (max_speed) before added up less, if less, current real time rate adds a preset value (such as if then judging current real time rate, maximum rate (max_speed) whether it is less than after 100KB/s), if it does, then illustrate that network environment there occurs bigger conversion, by current real time rate assignment to maximum rate (max_speed);
If interface is not in congested state, and currently real time rate is greater than max_speed, then by current real time rate assignment to maximum rate (max_speed);
Maximum rate and preset value (such as, 50kb/s) are compared, if maximum rate is greater than preset value, then according to the rate calculations shunting weight of interface; If maximum rate is not more than preset value, then determine shunting weight according to the time delay of interface.
In an embodiment of the present invention, whether detection interface is in congested state, is that the time delay by detecting interface is known, the time delay detecting method of interface has the following two kinds mode:
Mode one: send out one group of ping message (such as, often organizing 5 messages, each reports 64Bytes) every the default time (such as, 5 seconds) by interface, and obtain the time delay of interface according to the time difference receiving reply.
Mode two: by TCP tri-calculation delays of shaking hands, concrete: when receiving a syn+ack message, judge whether to be in SYN_SEND state, if being in, then obtain current system time, and the current system time of acquisition is subtracted the time that system sends syn message, obtain a time difference. This time difference is interface time delay.
If time delay is more than or equal to a preset value (such as, 1000ms), then this interface is labeled as and it is in congested state. If time delay is less than a preset value, then whether the syn message detecting this link retransmitted, if retransmitting, is then labeled as by this interface and is in congested state, time delay value is set as 1000ms; If not retransmitting, then interface is not in congested state, using time delay as interface of the time delay value that calculates.
In an embodiment of the present invention, when the rate calculations according to interface shunts weight, calculate according to following formula:
The maximum rate of shunting weight=the i-th interface of i-th interface/(maximum rate of maximum rate+the 2 interface of the 1st interface+... ... the maximum rate of+the i-th interface+... ...)
Shunt, according to interface rate calculations, the mode that weight also can adopt other, such as it will be understood that above-mentioned, setting the relation of speed scope with shunting weight in advance, when speed is when the first scope, shunting weight is 20%, and when the 2nd scope, shunting weight is 80% etc. mode.
When shunting weight according to time-delay calculation, time delay with shunting weight be inversely proportional to, such as, the time delay of the first interface be D1, the 2nd interface time delay be D2, then the shunting weight of the first interface is D2/ (D1+D2), and the weight of the 2nd interface is D1/ (D1+D2).
It will be understood that other mode also can be adopted to set the relation of time delay with shunting weight, such as, set time delay in advance when exceeding certain value, shunted weight and be set to the mode such as 0.
In an embodiment, if occurring presetting abnormal conditions, then give tacit consent to and shunt by the weight of 1:1. Such as, default abnormal conditions include but not limited to: when maximum rate is not more than preset value, and the time time delay of interface do not detected.
In an embodiment of the present invention, after have adjusted shunting weight by calculating, according to new shunting weight, the link set up new in data transmission procedure can be assigned to each interface to carry out the transmission of data service. Thus, in the embodiment of the present invention, a current route rule can be set up according to shunting weight. Current route rule is with the difference of initial route rule, is according to the shunting weight calculated, the link of foundation is assigned to each and is in connected state interface in current route rule. Such as, if interface is 3, the link number set up is 9, the shunting weight calculated is 3:4:2, then it is assigned to the link number that the first interface carries out transmitting and it is adjusted to 3, it is assigned to the link number that the 2nd interface carries out transmitting and it is adjusted to 4 articles, be assigned to the link number that the 3rd interface carries out transmitting and be adjusted to 2 articles.
Concrete, in order to ensure that the link set up is transmitted by corresponding interface according to shunting weight, in the embodiment of the present invention, adopt the mode of label link data packet, the data packet of link is marked. Thus, when transmitting, make different linking can walk corresponding interface according to the mark value of data packet and transmit.
See table 1, it is in an embodiment, the route rule formed after data packet being marked according to shunting weight.
Table 1
| Link | Mark value | Interface |
| 1 | 0X01 | Such as, first interface (WIFI interface) |
| 2 | 0X02 | Such as, 2nd interface (a LTE interface) |
| 3 | 0X03 | Such as, 3rd interface (the 2nd LTE interface) |
| ���� | ���� | ���� |
Mark value in table 1 is the mark value of the data packet in each link. In an embodiment of the present invention, first data packet of every bar link is marked, and data packet below then transmits according to the interface of first data packet.
Concrete, see Fig. 6, when marking: first obtain data packet, and the link judging this data packet follows the tracks of whether state is preset state. Whether, here, preset state is new state, be namely first data packet of this link;
If being preset state (being first data packet), then the interface being assigned with according to this link, marks this data packet, and mark value is preserved. Concrete, corresponding link can be saved in and follow the tracks of in mark; If not being preset state (not namely being first data packet), then the mark value of first data packet by this link preserved gives this data packet, and the mark value according to data packet, allocation of packets to corresponding interface is transmitted.
Thus, the data packet mark value in the embodiment of the present invention has double meaning, and one is to determine the link belonging to this data packet, and two is to determine which interface this data packet should be walked and transmit.
Owing to network environment is real-time change, the connected state of each interface, speed etc. are also real-time change, and therefore, the data transmission method of the embodiment of the present invention also comprises: in the transmitting procedure of data service, speed according to interface and time delay, adjustment shunting weight; And based on the shunting weight after adjustment, adjustment is assigned to the link number of the interface being respectively in connected state.
It will be understood that when carrying out data transmission, data service to be downloaded can be divided into the identical or different data block of multiple size, to be transmitted by many links set up respectively. Such as, by the APK of a 10M size, can being divided into 10 data blocks, the size of each data block is 1M, and each data block is transmitted by a link.
In certain embodiments, the maximum link number that terminal 100 can be set up is not necessarily equal with the data block divided, and such as, data block is 10, and the maximum link number set up is 5. Then when completing when being transmitted of a certain link, a newly-built link remaining data can be transmitted to continue accordingly. Thus, the embodiment of the present invention adjusts the link number being assigned to the interface being in connected state to be specially: by newly-built link according to the shunting weight allocation after adjustment to the interface being in connected state.

Embodiment 2
The difference of embodiments of the invention 2 and above-described embodiment is, when calculating shunting weight in example 2, only based on the speed of interface, and does not consider time delay. Concrete, see Fig. 7, the data transmission method of this embodiment comprises:
The connection of step S10, the in real time each interface of detection.
Step S20, when data service having been detected, set up at least one link.
It will be understood that the step S1 and step S2 of the specific implementation of step S10 and step S20 and details and above-described embodiment are identical, do not repeat them here.
Step S30, the shunting weight shunted weight according to 1:1 or obtain based on interface rate calculations, be assigned to the interface being in connected state to carry out the transmission of data service by the link of foundation. In an embodiment of the present invention, the shunting weight that weight comprises 1:1 and shunts weight and obtain based on interface rate calculations is shunted.
It will be understood that 1:1 shunts the embodiment details of weight and above-described embodiment is identical in the embodiment of the present invention, do not repeat them here.
In this embodiment of the invention, when calculating adjustment shunting weight, the speed of interface is only considered. Owing to speed embodies the size of interface bandwidth to a certain extent, carry out shunting the calculating of weight according to the size of speed, it is possible to make the calculating shunting weight simpler, and also can avoid congested.
Concrete, such as, preset time (such as, 1 second) docking port every one first and test the speed, and the rate calculations based on interface is shunted weight or shunted weight every the rate calculations that the default time (5 seconds) is corresponding according to interface.
In an embodiment of the present invention, the rate detection of interface is carried out in such a way:
Every default time (such as, 1 second), obtain the present rate of change as interface of interface byte number. Concrete, if first time detects the speed of a certain interface, then the byte number that detection obtains is preserved. If not first time detects the speed of a certain interface, then the interface byte number once acquired before being subtracted by the interface byte number acquired, the difference obtained is the present rate of this interface again divided by time of twice detection.
Owing in practice, the real time rate of interface is not enough to react the change of the network environment residing for interface, therefore, in one embodiment of this invention, calculating shunting weight according to the maximum rate of interface, concrete, the defining method of the maximum rate of interface is:
Docking port tests the speed, and detect whether interface is in congested state, if, whether than the maximum rate (max_speed) before added up less, if less, current real time rate adds a preset value (such as if then judging current real time rate, maximum rate (max_speed) whether it is less than after 100KB/s), if it does, then illustrate that network environment there occurs bigger conversion, by current real time rate assignment to maximum rate (max_speed);
If interface is not in congested state, and currently real time rate is greater than max_speed, then by current real time rate assignment to maximum rate (max_speed).
In an embodiment of the present invention, whether detection interface is in congested state, is that the time delay by detecting interface is known, the time delay detecting method of interface has the following two kinds mode:
Mode one: send out one group of ping message (such as, often organizing 5 messages, each reports 64Bytes) every the default time (such as, 5 seconds) by interface, and obtain the time delay of interface according to the time difference receiving reply.
Mode two: by TCP tri-calculation delays of shaking hands, concrete: when receiving a syn+ack message, judge whether to be in SYN_SEND state, if being in, then obtain current system time, and the current system time of acquisition is subtracted the time that system sends syn message, obtain a time difference. This time difference is interface time delay.
If time delay is more than or equal to a preset value (such as, 1000ms), then this interface is labeled as and it is in congested state. If time delay is less than a preset value, then whether the syn message detecting this link retransmitted, if retransmitting, is then labeled as by this interface and is in congested state, time delay value is set as 1000ms; If not retransmitting, then interface is not in congested state.
In an embodiment of the present invention, when the maximum rate according to interface calculates shunting weight, calculate according to following formula:
The maximum rate of shunting weight=the i-th interface of i-th interface/(maximum rate of maximum rate+the 2 interface of the 1st interface+... ... the maximum rate of+the i-th interface+... ...)
Shunt, according to interface rate calculations, the mode that weight also can adopt other, such as it will be understood that above-mentioned, setting the relation of speed scope with shunting weight in advance, when speed is when the first scope, shunting weight is 20%, and when the 2nd scope, shunting weight is 80% etc. mode.
In an embodiment of the present invention, after have adjusted shunting weight by calculating, according to new shunting weight, the link set up new in data transmission procedure can be assigned to each interface to carry out the transmission of data service. It will be understood that the difference of the embodiment of the present invention and above-described embodiment is only, in the present embodiment, when calculating adjustment shunting weight, only considering interface speed, other implements details and principle and above-described embodiment is identical, does not repeat them here.
By the data transmission method of the embodiment of the present invention, shunt based on interface speed, it is achieved utilize many data passage to transmit data simultaneously, optimize the allocation proportion of data stream greatly; Owing to speed embodies the size of interface bandwidth to a certain extent, more data stream should be carried with roomy interface, thus be not easy to occur that mass data circulates from the interface that bandwidth is little, the interface causing bandwidth little congested, cause time delay big, the situation of packet loss, it is to increase user tests.
