The communication station may comprise suitable hardware, logic, circuitry and/or code that may be operable to provide a data transmission channel. The data transmission channel is a physical data connection channel between the terminal 100 and the server 400.

Referring to fig. 2, the terminal 100 of an embodiment of the present invention may include a communication unit 110, an audio/video (a/V) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, a power supply unit 190, and the like. Fig. 2 shows a terminal having various components, but it is to be understood that not all of the shown components are required to be implemented. More or fewer components may alternatively be implemented.

The communication unit 110 typically includes one or more components that allow communication between the terminal 100 and a communication system or communication network. For example, the communication unit 110 may include a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115. In an embodiment of the present invention, the communication unit 110 includes at least one mobile communication module 112 and at least one wireless internet module 113.

In an embodiment of the present invention, the communication unit 110 includes at least one mobile communication module 112 and at least one wireless internet module 113. Thus, the terminal 100 of embodiments of the present invention may be in at least two different communication networks.

In the embodiment of the present invention, when the terminal 100 has a data download task, the terminal 100 performs channel quality measurement on a plurality of communication networks in which the terminal is currently located. In the embodiment of the present invention, specifically, when the terminal has a data download task, an available communication network is detected; if only one communication network is available, the data downloading task is completed by the communication network alone. If there are two or more available communication networks, the channel quality measurement is performed on a plurality of communication networks where the terminal is currently located, respectively.

The channel quality measurement includes at least one of: measuring the signal strength of the communication network, measuring the signal-to-noise ratio of the communication network, measuring the link estimation delay of the communication network, measuring the network bandwidth of the communication network, and acquiring the bandwidth support capability of the terminal.

Preferably, the terminal may estimate and measure the link delay by sending the preamble packet. Namely: the terminal sends a ping packet or a custom test data packet similar to the ping packet through the communication network, and records the time of returning ACK, thereby obtaining the link estimation delay. The ping packet and the custom test packet herein do not contain user data and are only used for link quality measurement. In addition, the signal strength, the signal-to-noise ratio, and the network bandwidth can be obtained from a broadcast message (a broadcast message issued by a base station site or the like).

The bandwidth support capability of the terminal 100 is determined by its own software, hardware environment (e.g., carrier aggregation manner adopted by the terminal 100, etc.), and information thereof may be stored in the terminal 100.

In the embodiment of the present invention, the terminal 100 generates a channel quality measurement result according to a protocol rule agreed with the server 400 in advance, and combines the channel quality measurement result with the data download request to generate a first data packet, and sends the first data packet to the server 400.

The data download request includes identification information for identifying an index of the data resource (e.g., an index ID of the APP1 to be downloaded) that the terminal 100 needs to download. The index may be an index primary key in a database table.

Preferably, the first data packet may adopt a message structure of TCP/IP or UDP. When the first data packet is sent, the communication network with the best channel quality can be selected for online data access according to the channel quality measurement result. For example, if the first communication network (e.g., WIFI network) has the strongest signal strength, the smallest link delay, and the highest signal-to-noise ratio, the first communication network is preferentially selected for uplink data access, and the first data packet is sent to the server 400 via the first communication network.

In the embodiment of the present invention, in addition to measuring the channel quality in real time, the channel quality measurement result may be obtained by:

(1) after the channel quality is measured in real time for the first time, the channel quality measurement result of the communication network where the terminal is located is stored, and when the terminal is located in the same communication network environment again, the channel quality measurement result can be directly obtained.

(2) Through statistical analysis, the estimated values of the signal intensity, the signal-to-noise ratio, the link estimation delay and the network bandwidth of each communication network are obtained, and the estimated values are stored in the terminal, so that the information of the signal intensity, the signal-to-noise ratio, the link estimation delay and the network bandwidth can be obtained by inquiring the stored information.

The server 400 allocates a data download task to each communication network according to the channel quality measurement result. Specifically, when the server 400 receives the first data packet, the unpacking operation is performed according to the agreed protocol rule to obtain the channel quality measurement result and the data downloading request, so that the server 400 can obtain the channel quality measurement result, the data resource required to be downloaded by the terminal, the size of the data resource, and other information.

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

step 10: allocating weights for signal strength, signal-to-noise ratio, link estimation delay, network bandwidth and bandwidth support capacity in advance;

step 11: calculating the channel quality of each communication network according to the received channel quality measurement result and the corresponding weight value;

step 12: and normalizing the channel quality of each communication network to determine the data downloading task of each communication network.

The assignment of data download tasks by the server 400 is described in detail below with reference to an example:

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

The server 400 allocates the following weights to the signal strength, the signal-to-noise ratio, and the link estimation delay in advance, respectively: 0.4, 0.1, 0.2. In practice, the smaller the network bandwidth and the bandwidth support capability of the terminal, the smaller the network bandwidth and the bandwidth support capability, so that the network bandwidth and the bandwidth support capability are distributed as a whole with the weight: 0.3. if the network bandwidth is smaller than the bandwidth supporting capability, the weight of the network bandwidth is 0.3 and the weight of the bandwidth supporting capability is 0; if the bandwidth supporting capability is smaller than the network bandwidth, the weight of the bandwidth supporting capability is 0.3 and the weight of the network bandwidth is 0; if the two are equal, the network bandwidth or bandwidth support capability is arbitrarily selected to allocate a weight of 0.3, and the other weight is 0.

According to the weight setting, if the received channel quality measurement results of the first communication network are respectively: the signal strength is 4, the signal-to-noise ratio is 12db, the link estimation delay is 0.1ms, the network bandwidth is 20MHz, and the bandwidth support capability is 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 received channel quality measurement results of the second communication network are respectively: the signal strength is 4, the signal-to-noise ratio is 10db, the link estimation delay is 0.5ms, the network bandwidth is 5MHz, and the bandwidth support capability is 20MHz, then the channel quality of the second communication network is:

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

then, P1 and P2 were normalized separately as follows:

the data download task for the first communication network is 68% and the data download task for the second communication network is 32%.

It should be understood that the data download tasks may be distributed to each communication network according to other algorithms, for example, an average distribution manner (for example, when the channel quality of two communication networks where the user is located is close, the data download tasks are distributed to each communication network by 50%), or a direct distribution manner according to the link estimation delay (for example, if the channel quality of one communication network is poor, for example, the link estimation delay is greater than 1ms, all the data download tasks are distributed to the other communication network). The assignment of the data download task may be set by the user, for example, the user may set the data download task of the first communication network to be fixed to 20% and the data download task of the second communication network to be fixed to 80% in order to save the traffic of the first communication network.

Therefore, after the data downloading task of each communication network is determined, the server divides the data required to be downloaded by the terminal into a plurality of data packets according to the data downloading task of each communication network. Preferably, the server splits the data packets according to a rule agreed with the terminal in advance, adds a packet header to each data packet after splitting to form a plurality of new data packets, and loads the plurality of data packets into the cache queue. In one embodiment, the data packets in the buffer queue are buffered, and the server does not delete the data packets until the terminal is confirmed to completely download the data packets.

For example, according to the above data downloading tasks of 68% and 32%, the data can be divided into a second data packet and a third data packet, which are downloaded through the first communication network and the second communication network respectively, wherein the data amount of the second data packet accounts for 68% of the total data amount, and the data amount of the third data packet accounts for 32% of the total data amount.

The server 400 divides the data to be downloaded by the terminal into a plurality of data packets according to the data download task of each communication network and loads the data packets into the cache queue. The terminal 100 downloads the corresponding data packet from the buffer queue through each communication network.

After the data packets are completely downloaded, the terminal 100 reassembles the data packets downloaded through each communication network to obtain the data that the terminal needs to download. Preferably, after the terminal 100 finishes downloading the data, unpacking the data according to a rule agreed with the server to obtain a data packet, and recombining (e.g., overlapping) the data packet according to an agreed server identifier to obtain complete data, thereby implementing downloading of the multi-channel data.

In this embodiment, according to the channel quality measurement result of the terminal, the channel quality of each communication network is analyzed, and the link quality, the link delay, the maximum bandwidth supported by the link, and the terminal capability (mainly, the bandwidth support capability, the carrier aggregation scheme, and the like) are comprehensively considered to comprehensively consider the more optimal communication network, so that the data download task (data load) of each communication network is adjusted, and the more optimal node is enabled to undertake more data packet download tasks. The received data packets are recombined at the terminal by splitting the data packets and then transmitting the data packets through multiple channels. Therefore, multichannel downloading of data is achieved, idle resources are fully utilized, the peak rate which can be achieved in the downloading process is the sum of multiple channels, the splitting of a large data packet is reduced, the overall transmission rate is improved, the throughput of the terminal is improved, and the user experience is improved.

In order to avoid the problems of data downloading failure and the like caused by communication network abnormality, an abnormality processing mechanism is added to the multi-channel data downloading system in the embodiment of the present invention, that is, in the data downloading process, when the terminal 100 detects that the communication network connection is abnormal (for example, the terminal 100 is disconnected from the WIFI communication network or the LTE communication network), the abnormality processing mechanism is started to download data. Specifically, the exception handling mechanism of this embodiment may be implemented in several ways:

the first method is as follows: the terminal 100 detects whether there is an abnormal communication network during data downloading, and if so, detects a time length during which the abnormal communication network (e.g., WIFI communication network) is abnormal, and if the time length exceeds a preset time length T1, sends a status packet to the server 400 through another normal communication network (e.g., LTE communication network) to notify the server 400 that there is an abnormality in the communication network and an interruption position for downloading through the abnormal communication network.

The server 400 receives the status packet, i.e. extracts the data packet to be downloaded (i.e. the data that has not been downloaded) from the cache, so that the terminal 100 switches to other normal communication networks, and continues downloading the data packet from the interrupt position to complete the downloading of the data resource (breakpoint resume).

The second method comprises the following steps: the server 400 compares the downloaded data amount with the abnormal download threshold value when receiving the status packet, and if the downloaded data amount is smaller than the abnormal download threshold value, notifies the terminal 100 to delete the data packet downloaded through the abnormal communication network, switches to the normal communication network, and downloads data again; and if the data is larger than the abnormal downloading threshold, downloading the data according to the first mode.

The third method comprises the following steps: the terminal 100 deletes the data packet downloaded through the abnormal communication network and switches to the normal communication network to download the data again.

Specifically, if there are 2 or more normal communication networks, the switching may be performed according to the above-mentioned channel quality measurement result (for example, switching to the communication network with the best channel quality measurement result), or according to the size of the data download amount completed by the normal communication network (for example, switching to the communication network with the largest data download amount), or performing the switching by considering the channel quality measurement result and the size of the completed data download amount comprehensively.

In this embodiment, the communication network anomaly includes the terminal being out of its coverage, a communication network service outage, and the like.

After the data is completely downloaded, the terminal 100 reassembles a plurality of data packets downloaded through different communication networks to obtain the data that the terminal needs to download.

By adding an exception handling mechanism, the problem of data downloading caused by network environment mutation can be avoided, the situation of data downloading failure under the abnormal condition of a communication network can be avoided, the high-speed and complete downloading of data is further ensured, the throughput of the terminal is improved, and the user experience is optimized.

Second embodiment

Referring to fig. 3 and 4, a flowchart of a multi-channel data downloading method according to a first embodiment of the present invention is shown. As shown in fig. 3, in the multi-channel data downloading method according to the first embodiment of the present invention, at the terminal, in step S01, the terminal performs channel quality measurement on each of the plurality of communication networks where the terminal is currently located. And after the channel quality measurement result is obtained, the terminal combines the channel quality measurement result into the data downloading request to generate a first data packet and sends the first data packet to the server. In step S02, the terminal downloads data through the plurality of communication networks according to the data download task assigned by the server to each communication network based on the channel quality measurement result. Specifically, the terminal downloads corresponding data packets through each communication network, wherein the data packets are data packets corresponding to each communication network, and the data packets are obtained by splitting data to be downloaded by the terminal into a plurality of data packets corresponding to each communication network based on a data downloading task of each communication network. In step S03, the terminal reassembles the plurality of data packets downloaded through different communication networks to obtain the data that the terminal needs to download.

Referring to fig. 4, at the side of the server, in step S101, a channel quality measurement result from the terminal is received. In step S102, a data download task is allocated for each communication network based on the channel quality measurement result. Specifically, after the server determines the data downloading task of each communication network, the server splits the data to be downloaded by the terminal into a plurality of data packets according to the data downloading task of each communication network, and loads the data packets into a cache queue for the terminal to download. When in use

It should be understood that the implementation principle and details of the multi-channel data downloading method of the second embodiment of the present invention are the same as those of the first embodiment described above, and are not described herein again.

In addition, in order to avoid the problem of communication network abnormality in the data downloading process, an abnormality processing mechanism is added in the multi-channel data downloading method in the embodiment of the present invention, that is, in the data downloading process, when the terminal 100 detects that the communication network connection is abnormal (for example, the terminal 100 is separated from the WIFI communication network or the LTE communication network), the abnormality processing mechanism is started to perform data downloading. Referring to fig. 5, specifically, after adding the exception handling mechanism, the method for downloading multi-channel data according to the embodiment of the present invention includes:

s11, the terminal measures the channel quality of each of the plurality of communication networks in which the terminal is currently located, and sends the channel quality measurement result to the server.

And S12, the server receives the channel quality measurement result from the terminal and distributes data downloading tasks for each communication network based on the channel quality measurement result.

And S13, the terminal downloads data through the plurality of communication networks according to the data downloading tasks distributed by the server for each communication network based on the channel quality measurement result.

S14, the terminal detects whether the data download is completed, if so, executes step S20, and if not, executes step S15.

S15, the terminal detects whether there is an abnormal communication network, if so, detects the abnormal time length of the abnormal communication network in step S16, and determines that the time length exceeds the preset time length T1 (e.g., 1 second) in step S17, otherwise, continues to execute step S14. If the preset time duration is exceeded, a status packet is sent to the server through other normal communication networks in step S18 to notify the server that there is an abnormality in the communication network and an interruption location for downloading through the abnormal communication network, and step S19 is executed, otherwise, step S14 is continued.

In step S19, when the server receives the status packet, it extracts the data packet to be downloaded from the buffer queue, and performs breakpoint transmission, or notifies the terminal to delete the data downloaded via the abnormal network and re-download the data packet, and then performs step S14. Specifically, the data can be continuously downloaded in any one of the following three ways:

the first method is as follows: carrying out breakpoint continuous transmission through a normal communication network, namely: and the server receives the state packet, extracts the data packet to be downloaded from the buffer queue, switches to a normal communication network, and continues to download the data packet from the interrupt position.

The second method comprises the following steps: the server 400 compares the downloaded data volume with the abnormal download threshold value when receiving the status packet, and if the downloaded data volume is smaller than the abnormal download threshold value, notifies the terminal 100 to delete the data packet downloaded through the abnormal communication network, and switches to the normal communication network to download the data again; and if the data is larger than the abnormal downloading threshold, downloading the data according to the first mode.

In step S20, the terminal reassembles the plurality of data packets downloaded through different communication networks to obtain the data that the terminal needs to download.

Before data downloading is not finished, if an abnormal communication network is recovered to be normal, the downloading position at the moment can be recorded, the communication network is switched to carry out breakpoint continuous transmission, and the network can be ignored, and other networks finish downloading. It should be understood that other ways may be used, and the embodiment of the present invention is not limited thereto.

Third embodiment

Fig. 6 is a network topology diagram of a multi-channel data downloading system according to a third embodiment of the present invention. In this embodiment, the communication networks available to the terminal 100 include an LTE communication network and a WIFI communication network, and the terminal 100 implements multi-channel data downloading through the LTE communication network and the WIFI communication network. Specifically, the multichannel data download system of the embodiment includes: server 400, LTE communication network 301, WIFI communication network 302, LTE station 201, WIFI station 202, and terminal 100. The terminal 100 is in communication connection with an LTE site 201 and a WIFI site 202 respectively; the LTE station 201 and the WIFI station 202 are respectively in communication connection with the server 400.

The LTE station 201 may comprise suitable hardware, logic, circuitry, and/or code that may be operable to provide a first data transmission channel. The first data transmission path establishes a first physical data connection path between the terminal 100 and the server 400. Specifically, the LTE station 201 faces the terminal 100, and the LTE communication network 301 faces the server 400.

The WIFI station 202 may comprise suitable hardware, logic, circuitry, and/or code that may be operable to provide a second data transmission channel. The second data channel is a second physical data connection channel between the terminal 100 and the server 400. The physical data channel includes: wireless channels and wired channels (between WIFI sites and servers). Specifically, the WIFI station 202 faces the terminal 100, and the WIFI communication network 302 faces the server 400.

The terminal 100 is configured to perform channel quality measurement on the LTE communication network 301 and the WIFI communication network 302 where the terminal is currently located.

In the embodiment of the invention, the terminal generates the channel measurement result according to the protocol rule agreed with the server in advance, combines the channel quality measurement result into the data downloading request to generate the first data packet, and sends the first data packet to the server.

The data downloading request contains identification information for identifying the index (for example, the index ID of the APP 1) of the data needing to be downloaded by the terminal. The index may be an index primary key in a database table.

Preferably, the first data packet may adopt a message structure of TCP/IP or UDP. When the first data packet is sent, a communication network (e.g., the WIFI communication network 302) with the best channel quality may be selected for online data access according to the channel quality measurement result.

The server 400 allocates data download tasks to the LTE communication network 301 and the WIFI communication network 302 according to the channel quality measurement result.

Specifically, the server receives the first data packet, performs unpacking operation according to the agreed protocol rule to obtain the channel measurement result and the data download request, so that the server can obtain the channel measurement result, the data resource required to be downloaded by the terminal, the size of the data resource, and the like.

Preferably, the server 400 may distribute the data downloading task by the weighting method, the average distribution, the distribution based on the estimated delay of the link, the distribution based on the user setting, and the like.

Thus, after determining the data download task of each communication network, the server 400 divides the data to be downloaded by the terminal 100 into the second data packet and the third data packet according to the data download task of each communication network. Preferably, the server 400 splits the data packets according to a rule agreed with the terminal in advance, adds a packet header to each data packet after splitting, forms a second data packet and a third data packet, and loads the second data packet and the third data packet into the cache queue. In one embodiment, the server 40 does not delete the buffered packets in the buffer queue until it is confirmed that the terminal 100 has completely downloaded.

For example, according to the data download tasks of 68% and 32%, the data can be split into a second data packet and a third data packet, wherein the data amount of the second data packet accounts for 68% of the total data amount, and the data amount of the third data packet accounts for 32% of the total data amount.

According to the data downloading task, the terminal 100 downloads the second data packet and the third data packet from the cache queue through the LTE communication network 301 and the WIFI communication network 302, respectively.

After the data packets are completely downloaded, the terminal 100 reassembles the data packets downloaded through the LTE communication network 301 and the WIFI communication network 302 to obtain data that the terminal needs to download. Preferably, after the terminal finishes downloading the data, unpacking the data according to a rule agreed with the server to obtain a data packet, and recombining (for example, overlapping) the data packet according to an agreed server identifier to obtain complete data, thereby realizing downloading of the multi-channel data.

In order to avoid data downloading failure caused by abnormality of the WIFI communication network or the LTE communication network in the data downloading process, an abnormality handling mechanism is added in the embodiment of the present invention, that is, in the data downloading process, when the terminal 100 detects that the communication network connection is abnormal (for example, the terminal 100 is disconnected from the WIFI communication network or the LTE communication network), the abnormality handling mechanism is started to download data. Specifically, the exception handling mechanism of this embodiment may be implemented in several ways:

The multi-channel data downloading system of the embodiment realizes multi-channel downloading of data through the LTE communication network and the WIFI communication network, realizes data aggregation of LTE + WIFI, fully utilizes idle resources, enables the peak rate to be the sum of multiple channels in the downloading process, and enables large data packets to be split and reduced,

the overall transmission rate is improved, the throughput of the terminal is improved, and the user experience is improved. And by adding an exception handling mechanism, the problem of data downloading caused by network environment mutation can be avoided, the situation of data downloading failure under the abnormal condition of a communication network can be avoided, the high-speed and complete downloading of data is further ensured, the throughput of the terminal is improved, and the user experience is optimized.

Fourth embodiment

Referring to fig. 7 and 8, a flowchart of a multi-channel data downloading method according to a fourth embodiment of the present invention is shown. Referring to fig. 7, in this embodiment, at one end of the terminal, in step S21, the terminal performs channel quality measurement on the LTE communication network and the WIFI communication network where the terminal is currently located, respectively. And after the channel quality measurement result is obtained, the terminal combines the channel quality measurement result into the data downloading request to generate a first data packet and sends the first data packet to the server. In step S22, the terminal downloads data through the LTE communication network and the WIFI communication network, respectively, according to the data download task allocated by the server to the LTE communication network and the WIFI communication network based on the channel quality measurement result. Specifically, the terminal downloads corresponding data packets through each communication network, wherein the data packets are data packets corresponding to the LTE communication network and the WIFI communication network, and the data packets are split into a plurality of data packets corresponding to the LTE communication network and the WIFI communication network by the server based on a data downloading task of each communication network. In step S23, the terminal reassembles the multiple data packets downloaded through the LTE communication network and the WIFI communication network to obtain the data that the terminal needs to download.

Referring to fig. 8, at the side of the server, in step S201, a channel quality measurement result from the terminal is received. In step S202, data download tasks are allocated for the LTE communication network and the WIFI communication network based on the channel quality measurement result. After determining the data downloading task of each communication network, the server divides the data to be downloaded by the terminal into two data packets (a second data packet and a third data packet) according to the data downloading task of each communication network, and loads the data packets into a cache queue for the terminal to download.

In the embodiment, the data aggregation of LTE + WIFI is realized, the multichannel downloading of data is realized, idle resources are fully utilized, the peak rate which can be reached in the downloading process is the sum of multiple channels, the large data packet is split and reduced, the overall transmission rate is improved, the throughput of the terminal is improved, and the user experience is improved.

Fig. 9 is a first timing diagram of a multi-channel data downloading method according to a fourth embodiment of the present invention. Terminal 100 establishes a first network connection with LTE site 201 and terminal 100 establishes a second network connection with WIFI site 202, such that terminal 100 is in both the LTE communication network and the WIFI communication network. When the terminal 100 has data to be downloaded, channel quality measurement is performed, and the channel quality measurement result is incorporated into the download request to generate a first data packet. The terminal 100 transmits the first data packet to the server 400 through the WIFI communication network or the LTE communication network (shown in fig. 6 as being transmitted through the LTE network). After receiving the first data packet, the server 400 returns an acknowledgement frame ACK to the terminal 100. The server 400 analyzes the first data packet to obtain a channel quality measurement result, and allocates a data download task for the LTE communication network and the WIFI communication network according to the channel quality measurement result. The server 400 allocates the data to be downloaded by the terminal 100 to the second data packet and the third data packet according to the data download task, and loads the second data packet and the third data packet into the buffer queue. The terminal 100 downloads the second data packet and the third data packet through the LTE communication network and the WIFI communication network, respectively. After the second data packet and the third data packet are downloaded through the dual channels, the terminal 100 performs unpacking and reassembly to obtain a complete data packet, so that the terminal 100 completes data downloading and returns an acknowledgement frame ACK to the server through the WIFI communication network or the LTE communication network.

In order to avoid data downloading failure caused by abnormality of the WIFI communication network or the LTE communication network in the data downloading process, an abnormality processing mechanism is added, that is, in the data downloading process, when the terminal 100 detects that the communication network connection is abnormal (for example, the terminal 100 is separated from the WIFI communication network or the LTE communication network), the abnormality processing mechanism is started to download data.

Referring to fig. 10, after the exception handling mechanism is added, in step S31, the terminal performs channel quality measurement on the LTE communication network and the WIFI communication network where the terminal is currently located, and sends the channel quality measurement result to the server. And after the channel quality measurement result is obtained, the terminal combines the channel quality measurement result into the data downloading request to generate a first data packet and sends the first data packet to the server. In step S32, the server receives the channel quality measurement result from the terminal, and allocates a data download task for the LTE communication network and the WIFI communication network based on the channel quality measurement result. After determining the data downloading task of each communication network, the server divides the data to be downloaded by the terminal into two data packets (a second data packet and a third data packet) according to the data downloading task of each communication network, and loads the two data packets into a cache queue. In step S33, the terminal downloads data through the LTE communication network and the WIFI communication network, respectively, according to the data download task allocated by the server to the LTE communication network and the WIFI communication network based on the channel quality measurement result.

In step S34, the terminal detects whether the data download is completed, and if so, executes step S40, and if not, executes step S35.

In step S35, the terminal detects whether there is an abnormal communication network, if so, detects the abnormal time length of the abnormal communication network in step S36, and determines that the time length exceeds a preset time length T1 (e.g., 1 second) in step S37, otherwise, continues to execute step S34. If the preset time duration is exceeded, a status packet is sent to the server through other normal communication networks in step S38 to notify the server that there is an abnormality in the communication network and an interruption location for downloading through the abnormal communication network, and step S39 is executed, otherwise, step S34 is continued.

In step S39, when the server receives the status packet, it extracts the data packet to be downloaded from the buffer queue, and performs breakpoint transmission, or notifies the terminal to delete the data downloaded via the abnormal network and re-download the data packet, and then performs step S34. Specifically, the data can be continuously downloaded in any one of the following three ways:

In step S40, the terminal reassembles the plurality of data packets downloaded through different communication networks to obtain the data that the terminal needs to download.

Fig. 11 is a second timing chart of a multi-channel data downloading method according to a fourth embodiment of the invention. Terminal 100 establishes a first network connection with LTE site 201 and terminal 100 establishes a second network connection with WIFI site 202, such that terminal 100 is in both the LTE communication network and the WIFI communication network. When the terminal 100 has data to be downloaded, channel quality measurement is performed, and the channel quality measurement result is incorporated into the download request to generate a first data packet. The terminal 100 transmits the first data packet to the server 400 through the WIFI communication network or the LTE communication network (shown in fig. 6 as being transmitted through the LTE network). After receiving the first data packet, the server 400 returns an acknowledgement frame ACK to the terminal 100. The server 400 analyzes the first data packet to obtain a channel quality measurement result, and allocates a data download task for the LTE communication network and the WIFI communication network according to the channel quality measurement result. The server 400 allocates the data to be downloaded by the terminal 100 to the second data packet and the third data packet according to the data download task, and loads the second data packet and the third data packet into the buffer queue. The terminal 100 downloads the second data packet and the third data packet through the LTE communication network and the WIFI communication network, respectively. The terminal 100 finishes downloading the second and third data packets through the dual channel. In the downloading process, if it is detected that the communication network is abnormal and the abnormal duration exceeds the preset value, a status packet is generated and sent to the server 400 through the normal communication network (shown as the LTE communication network in fig. 9). The status packet contains the interrupt location. After receiving the status packet, the server 400 extracts the data packet to be downloaded from the cache queue, and switches to the normal communication network to enable the terminal 100 to continue downloading the data packet from the interrupted location (or continue downloading the data packet in the above-mentioned manner two or three). Therefore, after the second data packet and the third data packet are downloaded through the dual channels, the terminal 100 performs unpacking and reassembly to obtain a complete data packet. The terminal 100 completes the data download, and the normal communication network (shown as the LTE communication network in fig. 9) returns an acknowledgement frame ACK to the server.

The multichannel data download system of this embodiment realizes the multichannel download of data through LTE communication network and WIFI communication network, has realized LTE + WIFI's data aggregation, make full use of idle resource for can reach the peak rate and be the multichannel sum in the download process, through reducing big data packet split, improve holistic transmission rate, improve the throughput at terminal, promote user experience.
