In an embodiment of the present invention, in the time that terminal 100 has data downloading task, terminal 100 is carried out channel quality measurement to current residing multiple communication networks. In an embodiment of the present invention, concrete, in the time that terminal has data downloading task, detect available communication network; If only have an available communication network, complete separately data downloading task by this communication network. If there are two or more available communication network, the current residing multiple communication networks of terminal are carried out respectively to channel quality measurement.

Channel quality measurement at least comprises one of them: measure the signal strength signal intensity of communication network, the signal to noise ratio of measuring communication network, the link of measuring communication network estimate time delay, measure communication network the network bandwidth, obtain the bandwidth tenability of terminal.

Preferably, terminal can, by sending the mode of preamble packet, be estimated to measure to link delay. That is: terminal sends the self-defined test packet of a ping bag or similar ping bag by communication network, and record returns to the time of ACK, obtains thus link and estimates time delay. Here ping bag and self-defined test packet do not comprise user data, only for link quality measurements. In addition, signal strength signal intensity, signal to noise ratio and the network bandwidth can obtain from broadcast (broadcast that base station site etc. issue).

The bandwidth tenability of terminal 100 determines (for example, the carrier aggregation mode that terminal 100 is taked etc.) by itself software, hardware environment, and its information can be stored in terminal 100.

In an embodiment of the present invention, terminal 100 generates channel quality measurements according to shifting to an earlier date the protocol rule of appointing with server 400, and channel quality measurements integrated with to data download request generate the first packet, and by this first Packet Generation to server 400.

In data download request, include identification information, need the index (for example, needing the index ID of the application APP1 downloading) of downloading data resource for marking terminal 100. Index can be the index major key in database table.

Preferably, the first packet can adopt the message structure of TCP/IP or UDP. While sending the first packet, can be according to channel quality measurements, the top-quality communication network of the selective channel data access of reaching the standard grade. For example, for example, if the first communication network (, WIFI network) signal strength signal intensity the strongest, chain-circuit time delay is minimum, signal to noise ratio is the highest, preferentially selects this first communication network to carry out upstream data access, and the first packet is sent to server 400 through the first communication network.

In an embodiment of the present invention, except real-time measure channel quality, also can obtain in the following manner channel quality measurements:

(1) for the first time in real time after measure channel quality, i.e. the channel quality measurements of the residing communication network of storage terminal, when terminal is during again in same communication network environment, can directly get channel quality measurements.

(2) by statistical analysis, obtain the estimated value of each communication network signal strength signal intensity, signal to noise ratio, link estimation time delay and the network bandwidth, and estimated value is stored in terminal, thus, get final product the information of picked up signal intensity, signal to noise ratio, link estimation time delay and the network bandwidth by inquiry canned data.

Server 400, according to channel quality measurements, is each communication network distribute data downloading task. Concrete, server 400 receives the first packet, good protocol rule is separated package operation according to a preconcerted arrangement, to obtain channel quality measurements and data download request, thus, server 400 can get the information such as the size of channel quality measurements, the required downloading data resource of terminal, this data resource.

Preferably, in an embodiment of the present invention, server 400 is each communication network distribute data downloading task according to following preset algorithm:

Step 10: be signal strength signal intensity, signal to noise ratio, link estimation time delay, the network bandwidth, bandwidth tenability distribution weights in advance;

Step 11: the channel quality that calculates each communication network according to the channel quality measurements receiving and its corresponding weights;

Step 12: the channel quality of each communication network is normalized, to determine the data downloading task of each communication network.

Below in conjunction with an example, server 400 distribute data downloading task are elaborated:

In this example, suppose that terminal 100 is in two available communication networks (the first communication network and second communication network).

Server 400 is in advance for signal strength signal intensity, signal to noise ratio, link estimate that time delay distributes respectively following weights: 0.4,0.1,0.2. In practice, the bandwidth tenability of the network bandwidth and terminal, need be as the criterion with smaller, and therefore, it is that it distributes weights that the network bandwidth and bandwidth tenability are done as a whole: 0.3. If the network bandwidth is less than bandwidth tenability, be as the criterion with the network bandwidth, its weights are 0.3, and the weights of bandwidth tenability are 0; If bandwidth tenability is less than the network bandwidth, be as the criterion with bandwidth tenability, its weights are 0.3, and the weights of the network bandwidth are 0; If the two equate, appoint and get the network bandwidth or bandwidth tenability for its distribution weights 0.3, and another one weights are 0.

According to above-mentioned weight setting, if the channel quality measurements of the first communication network receiving is respectively: signal strength signal intensity is 4, signal to noise ratio is 12db, link is estimated time delay 0.1ms, network bandwidth 20MHz, bandwidth tenability 20MHz, and the channel quality of the first communication network is:

P1＝0.4×4+0.1×12+0.2×0.1+0.3×20+0×20＝8.82

The channel quality measurements of the second communication network receiving is respectively: signal strength signal intensity is 4, signal to noise ratio is 10db, link is estimated time delay 0.5ms, network bandwidth 5MHz, bandwidth tenability 20MHz, and the channel quality of second communication network is:

P2＝0.4×4+0.1×10+0.2×0.5+0.3×5+0×20＝4.2

Then, respectively P1 and P2 are normalized in the following manner:

$\frac{P1}{P1+P2}=\frac{8.82}{8.82+4.2}\≈0.68$

$\frac{P2}{P1+P2}=\frac{4.2}{8.82+4.2}\≈0.32$

The data downloading task that obtains the first communication network is 68%, and the data downloading task of second communication network is 32%.

Should understand, can be also each communication network distribute data downloading task according to other algorithm, for example, (for example adopt the mode of mean allocation, in the time that the channel quality of residing two communication networks of user approaches, for the data downloading task of its distribution is each 50%), or the mode of directly distributing according to link estimation time delay (for example, if the channel quality of a certain communication network is very poor, for example, when link estimates that time delay is greater than 1ms, total data downloading task is distributed to alternative communication network). In addition, also can be arranged the distribution of data downloading task by user, for example, user is in order to save the flow of the first communication network, the data downloading task of the first communication network fixedly can be made as to 20%, the data downloading task of second communication network is fixedly made as to 80%.

Thus, determined after the data downloading task of each communication network, server is according to the data downloading task of each communication network, and the Data Division that terminal need to be downloaded is multiple packets. Preferably, server, according to the rule shifting to an earlier date and terminal is appointed, carries out the fractionation of packet, after splitting, adds packet header for each packet, forms multiple new packets, and the plurality of packet is loaded into buffer queue. In one embodiment, the data cached bag in buffer queue, until after confirming that terminal has all been downloaded, server is just by its deletion.

For example, according to above-mentioned 68% and 32% data downloading task, can be that the second packet and the 3rd packet are downloaded by the first communication network and second communication network respectively by Data Division, the data volume that wherein data volume of the second packet accounts for 68%, the three packet of total amount of data accounts for 32% of total amount of data.

Server 400 is according to the data downloading task of each communication network, and the Data Division that terminal need to be downloaded is multiple packets and is written into after buffer queue. Terminal 100 by each communication network, is downloaded corresponding packet respectively from buffer queue.

After packet is all downloaded, terminal 100 will recombinate to obtain the data that terminal need to be downloaded by the packet of each downloaded. Preferably, terminal 100 completes data download after, according to unpacking with the good rule of server commitment, obtain packet, and packet is recombinated according to the server identification of agreement (for example, stack), to obtain complete data, thus, realize the download of multi-channel data.

In this embodiment, according to the channel quality measurements of terminal, analyze the channel quality of each communication network, consider link-quality, link delay, link and support that maximum bandwidth, terminal capability (are mainly bandwidth tenabilities, carrier aggregation scheme etc.), with the more excellent communication network of comprehensive consideration, thereby adjust the data downloading task (data load) of each communication network, make more excellent node bear more packet downloading task. After packet is split, transmit by multichannel, in end, the packet receiving is recombinated again. Realize thus the multichannel of data and download, make full use of slack resources, making can reach peak rate in downloading process is multichannel sum, by large packet is split and is diminished, improve overall transfer rate, improved the handling capacity of terminal, promoted user's experience.

The problems such as the data failed download extremely causing for fear of communication network, in the multi-channel data download system of the embodiment of the present invention, add exception handling, in data downloading process, terminal 100 detects that communication network (for example connects when abnormal, terminal 100 departs from WIFI communication network or LTE communication network), start exception handling and carry out data download. Concrete, the exception handling of this embodiment can be realized by following several modes:

Mode one: terminal 100 is in data downloading process, detect and whether have abnormal communication network, if have, detect exceptional communication network (for example, WIFI communication network) abnormal duration occurs, if this duration exceedes default duration T1, by other normal communication network (for example, LTE communication network) send state bag to server 400, there is communication network to occur extremely with announcement server 400, and the interruption position of downloading by exceptional communication network.

Server 400 receives state bag and from buffer memory, extracts packet to be downloaded (data that are not also downloaded), make terminal 100 switch to other normal communication network, and continue downloading data bag to complete the download (breakpoint transmission) of data resource from interrupting position.

Mode two: server 400 receives state bag, downloading data amount and the abnormal threshold value of downloading are compared, if be less than abnormal download threshold value, notification terminal 100 is deleted the packet of having downloaded by exceptional communication network, and switch to normal communication network, and re-start data download; If be greater than abnormal download threshold value, carry out data download according to mode one.

Mode three: terminal 100 is deleted the packet of having downloaded by exceptional communication network, and switch to normal communication network re-start data download.

Concrete, if normal communication network has more than 2 or 2, can (for example switch according to above-mentioned channel quality measurements, switch to the best communication network of channel quality measurements), also can (for example switch according to the completed data download of proper communication network size, switch to the communication network that data download completes at most), or consider channel quality measurements and completed data download size is switched.

In this embodiment, communication network comprises that terminal departs from its coverage, communications network service interruption etc. extremely.

After data have all been downloaded, terminal 100 recombinates to obtain by multiple packets of downloading by different communication network the data that terminal need to be downloaded.

By adding exception handling, can avoid the data download problem causing because network environment is suddenlyd change, can avoid under communication network abnormal conditions, the situation of data failed download, further guarantee high speed and the complete download of data, improve the handling capacity of terminal, optimizing user is experienced.
