Server 400, according to channel quality measurements, is each communication network distribute data downloading task.Concrete, server 400 receives the first packet, then good according to a preconcerted arrangement protocol rule carries out de-packaging operation, to obtain channel quality measurements and data download request, thus, server 400 can get the information such as the size of downloading data resource, this data resource required for channel quality measurements, terminal.
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: according to the channel quality of the channel quality measurements received with each communication network of weight computing of its correspondence;
Step 12: be normalized by the channel quality of each communication network, to determine the data downloading task of each communication network.
Below in conjunction with an example, server 400 distribute data downloading task is described in detail:
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 following weights respectively: 0.4,0.1,0.2.In practice, the bandwidth tenability of the network bandwidth and terminal, need be as the criterion with smaller, therefore, is integrally its distribution weights: 0.3 by the network bandwidth and bandwidth tenability.If the network bandwidth is less than bandwidth tenability, be then 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 then as the criterion with bandwidth tenability, its weights are 0.3, and the weights of the network bandwidth are 0; If the two is equal, then appoint that to get the network bandwidth or bandwidth tenability be that it distributes 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 received is respectively: signal strength signal intensity is 4, signal to noise ratio is 12db, link estimates time delay 0.1ms, network bandwidth 20MHz, bandwidth tenability 20MHz, then 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 received is respectively: signal strength signal intensity is 4, signal to noise ratio is 10db, link estimates time delay 0.5ms, network bandwidth 5MHz, bandwidth tenability 20MHz, then 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 is normalized in the following manner:
The data downloading task then obtaining 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, such as, adopt the mode of mean allocation (such as, when the communication network of two residing for user channel quality close to time, the data downloading task of distributing for it is each 50%), or directly carry out the mode of distributing (such as according to link estimation time delay, if the channel quality of a certain communication network is very poor, such as, 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, such as, 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 set to 20%, the data downloading task of second communication network is fixedly set to 80%.
Thus, after determining the data downloading task of each communication network, terminal, according to the data downloading task of each communication network, needs the Data Division downloaded to be multiple packet by server.Preferably, server, according to the rule shifted to an earlier date and terminal is appointed, carries out the fractionation of packet, adds packet header, form multiple new packet, and the plurality of packet is loaded into buffer queue after splitting for each packet.In one embodiment, the data cached bag in buffer queue, until after confirming that terminal has all been downloaded, server is just deleted.
Such as, according to the data downloading task of above-mentioned 68% and 32%, can be that the second packet and the 3rd packet are respectively by the first communication network and second communication web download by Data Division, wherein the data volume of the second packet accounts for 68% of total amount of data, and the data volume of the 3rd packet accounts for 32% of total amount of data.
Terminal, according to the data downloading task of each communication network, needs the Data Division downloaded to be multiple packet and after being loaded into buffer queue by server 400.Terminal 100, respectively by each communication network, downloads corresponding packet from buffer queue.
After packet is all downloaded, the packet by each downloaded is carried out the data recombinating to obtain the download of terminal needs by terminal 100.Preferably, terminal 100 is unpacked according to the rule good with server commitment after completing data download, obtain packet, and packet is recombinated (such as, superposing) according to the server identification of agreement, to obtain complete data, thus, the download of multi-channel data is realized.
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 support maximum bandwidth, terminal capability (mainly bandwidth tenability, carrier aggregation scheme etc.), with the more excellent communication network of comprehensive consideration, thus adjust the data downloading task (data load) of each communication network, make the more packet downloading task of more excellent node assumes.Transmitted by multichannel after packet is split, in end, the packet received is recombinated again.The multichannel realizing data is thus downloaded, and make full use of slack resources, making to reach peak rate in downloading process is multichannel sum, diminish by large packet is split, improve overall transmission rate, improve the throughput of terminal, improve Consumer's Experience.
The problems such as the data failed download caused in order to avoid communication network is abnormal, exception handling is added in the multi-channel data download system of the embodiment of the present invention, namely in data downloading process, when terminal 100 detects that communication network connects abnormal (such as, terminal 100 departs from WIFI communication network or LTE communication network), then start exception handling and carry out data download.Concrete, the exception handling of this embodiment realizes by following several mode:
Mode one: terminal 100 is in data downloading process, detect and whether have abnormal communication network, if have, then detect exceptional communication network (such as, WIFI communication network) and abnormal duration occurs, if this duration exceedes preset duration T1, then by other normal communication network (such as, LTE communication network) send state bag to server 400, there is communication network to there occurs exception with announcement server 400, and pass through the interruption position of exceptional communication web download.
Server 400 receives state bag from buffer memory, namely extracts packet to be downloaded (data be not namely 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 interruption position.
Mode two: server 400 receives state bag, then downloading data amount is downloaded threshold value compare with abnormal, if be less than exception to download threshold value, then notification terminal 100 is deleted by the packet of exceptional communication web download, and switch to normal communication network, and re-start data download; Extremely download threshold value if be greater than, then carry out data download according to mode one.
Mode three: terminal 100 is deleted by the packet of exceptional communication web download, and switch to normal communication network re-start data download.
Concrete, if normal communication network has more than 2 or 2, then can carry out switching (such as according to above-mentioned channel quality measurements, switch to the communication network that channel quality measurements is best), also can carry out switching (such as according to normal communication network completed data download size, switch to the communication network that data download completes at most), or consider channel quality measurements and completed data download size switches.
In this embodiment, comprise terminal departs from its coverage, communications network service interruption etc. to communication network extremely.
After data have all been downloaded, the multiple packets downloaded by different communication network are carried out the data recombinating to obtain the download of terminal needs by terminal 100.
By adding exception handling, the data download problem caused because network environment is suddenlyd change can be avoided, under communication network abnormal conditions can be avoided, the situation of data failed download, guarantee the high speed of data and complete download further, improve the throughput of terminal, optimizing user is experienced.
