The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication means such as wired and wireless communication means and satellite-based communication means that transmit data via frames or packets.
A communication apparatus in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.
Such communication devices may use different air interfaces and/or physical layers. For example, the air interface used by the communication device includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and universal mobile telecommunications device (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and so forth. The following description relates to a CDMA communication device, as a non-limiting example, but such teachings are equally applicable to other types of devices.
Referring to fig. 2, the CDMA wireless communication apparatus may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that an apparatus as shown in fig. 2 may include a plurality of BSCs 2750.
Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).
The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a base transceiver sub-assembly (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.
As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the apparatus. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several global positioning device (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.
In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. As a typical operation of the wireless communication apparatus, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.
Based on the hardware structure and the communication device structure of the mobile terminal, the invention provides various embodiments of the split-screen display device of the mobile terminal, and the network switching device is a part of the mobile terminal.
Referring to fig. 3, the present invention provides a network switching apparatus, which in a first embodiment of the network switching apparatus comprises:
the first detection module 10 is configured to detect a wireless signal strength of a wireless network to which the mobile terminal is connected at the current time;
the WIreless network providing the WIreless signal may be a wifi (WIreless-Fidelity) hotspot, a zigbee (zigbee protocol) hotspot, or other WIreless hotspots, taking the wifi hotspot as an example, a wifi hotspot list is obtained, and if the mobile terminal is connected to only one wifi hotspot, the first detection module 10 detects the WIreless signal intensity provided by the wifi hotspot in real time to compare with a first preset threshold; if the mobile terminal is connected to a plurality of wifi hotspots at the same time, the first detection module 10 detects the wireless signal intensity provided by all the wifi hotspots in real time, and compares the wireless signal with the maximum signal intensity with a preset first preset threshold value as a reference. For example, the mobile terminal is simultaneously connected to wifi hotspots a and B, the signal strength of wifi hotspot a is 10 units (for example, the unit may be decibel), the signal strength of wifi hotspot B is 20 units, and the wireless signal strength of wifi hotspot B is compared with the first preset threshold.
The first starting module 20 is configured to start a mobile data network channel of the mobile terminal when detecting that the wireless signal strength is smaller than a first preset threshold and lasts for a first preset duration.
When the intensity of the wireless signal received by the mobile terminal is detected to be smaller than a first preset threshold value, timing is started, and the intensity of the wireless signal received by the mobile terminal is continuously detected; when detecting that the intensity of the wireless signal received by the mobile terminal is less than the first preset threshold value for a first preset duration (for example, 10s), the first enabling module 20 enables the mobile data network channel of the mobile terminal, for example, if a 4G (fourth generation mobile communication technology) card is installed inside the mobile terminal, the 4G network of the mobile terminal is enabled. And if the intensity of the wireless signal received by the mobile terminal is recovered to be normal within the first preset time length, namely the intensity is greater than a first preset threshold value, timing is cancelled.
Furthermore, to avoid a situation: the wireless signal intensity of the wireless hotspot is high, but the bandwidth provided by the wireless hotspot is low, that is, the download speed of the mobile terminal after receiving the wireless signal is low, so that when the wireless signal intensity of the wireless network connected with the mobile terminal at the current moment is detected, the download speed provided by the wireless signal is detected at the same time, if the download speed is lower than a preset download speed (for example, 10Kb/s) and lasts for a third preset time (for example, 10s), the user can use the wireless network to ensure the operation of the related network application, so that the mobile data network channel of the mobile terminal is also opened at this time to ensure the network bandwidth required by internet access, and the situation of network disconnection is avoided.
In this embodiment, the first detection module 10 detects the wireless signal strength of the wireless network connected to the mobile terminal at the current moment; then, when it is detected that the wireless signal intensity is smaller than the first preset threshold and lasts for the first preset duration, the first opening module 20 opens the mobile data network channel of the mobile terminal, that is, when a wireless network (such as wifi) connected to the mobile terminal fails, is invalid and has poor network status, the mobile data network channel of the mobile terminal can be automatically opened by a user to realize automatic network switching, thereby avoiding network disconnection of the mobile terminal due to instability of the wireless network, ensuring smooth and stable network access of the user, avoiding the user from missing important network information, network notification and the like due to network problems, and improving the user experience of network access.
Further, on the basis of the first embodiment of the network switching apparatus of the present invention, a second embodiment of the network switching apparatus is proposed, and in the second embodiment, the network switching apparatus further includes:
a second detection module 30 for detecting an external wireless signal strength of a wireless network externally connectable to the mobile terminal;
and the connection speed-limiting module 40 is used for connecting the corresponding wireless network and closing or limiting the mobile data network channel of the mobile terminal when detecting that the intensity of the external wireless signal is greater than the second preset threshold value and continues for a second preset duration.
After the mobile data network channel of the mobile terminal is opened, the external wireless signal intensity of the wireless network connectable outside the scene where the mobile terminal is located is detected by the second detection module 30, if the detected external wireless signal intensity is greater than the second preset duration, that is, if the mobile terminal detects that the signal intensity of the external wireless network is greater and the network environment is better, the connection speed-limiting module 40 controls the mobile terminal to connect to the corresponding wireless network, and simultaneously closes or limits the mobile data network channel of the mobile terminal, so that when the external wireless network returns to normal, the mobile data network channel of the mobile terminal is closed or limited in time, and the user is helped to save the mobile network traffic needing to be paid.
In addition, the download speed allowed by the mobile data network channel of the mobile terminal may be correspondingly adjusted according to the magnitude of the external wireless signal strength, where the adjustment range of the download speed is 0 to V (preset maximum download speed), for example, when the external wireless signal strength is greater than a second preset threshold, the external wireless signal strength is divided into three levels, i.e., low, medium and high, according to a preset rule, and when the external wireless signal strength is at a low level, the download speed of the mobile data network channel of the mobile terminal is limited to 0.8V; when the intensity of the external wireless signal is in a medium level, the download speed of the mobile data network channel of the mobile terminal is limited to 0.5V, and when the intensity of the external wireless signal is in a high level, the download speed of the mobile data network channel of the mobile terminal is limited to 0, so that the download speed of the mobile data network channel of the mobile terminal is intelligently and dynamically adjusted according to the intensity of the external wireless signal.
Further, on the basis of the first embodiment of the network switching apparatus of the present invention, a third embodiment of the network switching apparatus is proposed, and in the third embodiment, the network switching apparatus further includes:

and the prompting module 60 is configured to close or limit the mobile data network channel of the mobile terminal when the flow consumed by statistics reaches a preset flow threshold, and prompt the user of the current remaining flow.
After the mobile data network channel of the mobile terminal is opened, the traffic counting module 50 counts the traffic consumed by the mobile data network channel of the mobile terminal, when the counted consumed traffic reaches a preset traffic threshold (for example, 100M), which indicates that the network behavior performed by the user using the mobile terminal consumes more traffic at this time, the user needs to be reminded, at this time, the prompt module 60 outputs a preset prompt message (the prompt message may be in the form of one or more of voice, image, video, and vibration), the content of the hint information may include the current remaining traffic of the user, a prompt to the user to check if there is a heavy traffic consuming application that is running hidden, meanwhile, the prompt module 60 closes or limits the mobile data network channel of the mobile terminal, so as to prevent the mobile terminal from consuming too much mobile network traffic to cause that the monthly traffic consumed by the user exceeds the standard.
In addition, on the basis of the second embodiment of the network switching apparatus of the present invention, the network switching apparatus further includes:

The present invention also provides a network switching method, which is mainly applied to a mobile terminal, and in a first embodiment of the network switching method, referring to fig. 8, the network switching method includes:
step S10, detecting the wireless signal intensity of the wireless network connected with the mobile terminal at the current moment;
the WIreless network providing the WIreless signal can be a wifi (WIreless-Fidelity) hotspot, a zigbee (zigbee protocol) hotspot and other WIreless hotspots, taking the wifi hotspot as an example, a wifi hotspot list is obtained, and if the mobile terminal is connected with only one wifi hotspot, the WIreless signal intensity provided by the wifi hotspot is detected in real time to be compared with a first preset threshold; if the mobile terminal is connected with a plurality of wifi hotspots simultaneously, the wireless signal intensity provided by all the wifi hotspots is detected in real time, and the wireless signal with the maximum signal intensity is used as a reference to be compared with a preset first preset threshold value. For example, the mobile terminal is simultaneously connected to wifi hotspots a and B, the signal strength of wifi hotspot a is 10 units (for example, the unit may be decibel), the signal strength of wifi hotspot B is 20 units, and the wireless signal strength of wifi hotspot B is compared with the first preset threshold.
Step S20, when it is detected that the wireless signal strength is less than the first preset threshold and lasts for the first preset duration, the mobile data network channel of the mobile terminal is opened.
When the intensity of the wireless signal received by the mobile terminal is detected to be smaller than a first preset threshold value, timing is started, and the intensity of the wireless signal received by the mobile terminal is continuously detected; when detecting that the intensity of the wireless signal received by the mobile terminal is less than a first preset threshold value for a first preset duration (for example, 10s), opening a mobile data network channel of the mobile terminal, for example, if a 4G (fourth generation mobile communication technology) card is installed inside the mobile terminal, opening a 4G network of the mobile terminal. And if the intensity of the wireless signal received by the mobile terminal is recovered to be normal within the first preset time length, namely the intensity is greater than a first preset threshold value, timing is cancelled.
Furthermore, to avoid a situation: the wireless signal intensity of the wireless hotspot is high, but the bandwidth provided by the wireless hotspot is low, that is, the download speed of the mobile terminal after receiving the wireless signal is low, so that when the wireless signal intensity of the wireless network connected with the mobile terminal at the current moment is detected, the download speed provided by the wireless signal is detected at the same time, if the download speed is lower than a preset download speed (for example, 10Kb/s) and lasts for a third preset time (for example, 10s), the user can use the wireless network to ensure the operation of the related network application, so that the mobile data network channel of the mobile terminal is also opened at this time to ensure the network bandwidth required by internet access, and the situation of network disconnection is avoided.
In the embodiment, the wireless signal strength of the wireless network connected with the mobile terminal at the current moment is detected; then, when the wireless signal intensity is detected to be smaller than a first preset threshold value and the first preset duration lasts, a mobile data network channel of the mobile terminal is started, namely when a wireless network (such as wifi) connected with the mobile terminal breaks down, is invalid and has poor network conditions, the mobile data network channel of the mobile terminal can be automatically started by a user to realize automatic network switching, the phenomenon that the mobile terminal breaks down due to instability of the wireless network is avoided, smooth and stable internet surfing of the user is guaranteed, the phenomenon that the user omits important network information, network notification and the like due to network problems is avoided, and internet surfing experience of the user is improved.

step S30, detecting the external wireless signal intensity of the wireless network which can be connected with the outside of the mobile terminal;
and step S40, when the external wireless signal strength is detected to be greater than the second preset threshold value and the second preset duration continues, connecting the corresponding wireless network, and closing or limiting the mobile data network channel of the mobile terminal.
After a mobile data network channel of the mobile terminal is opened, detecting the external wireless signal intensity of a wireless network which can be connected outside a scene where the mobile terminal is located in real time, and if the detected external wireless signal intensity is greater than a second preset duration, namely the mobile terminal detects that the signal intensity of the external wireless network is greater and the network environment is better, controlling the mobile terminal to be connected with the corresponding wireless network and simultaneously closing or limiting the mobile data network channel of the mobile terminal, so that when the external wireless network is recovered to be normal, the mobile data network channel of the mobile terminal is closed or limited in time, and the mobile network flow needing to be paid is saved for a user.
In addition, the download speed allowed by the mobile data network channel of the mobile terminal may be correspondingly adjusted according to the magnitude of the external wireless signal strength, where the adjustment range of the download speed is 0 to V (preset maximum download speed), for example, when the external wireless signal strength is greater than a second preset threshold, the external wireless signal strength is divided into three levels, i.e., low, medium and high, according to a preset rule, and when the external wireless signal strength is at a low level, the download speed of the mobile data network channel of the mobile terminal is limited to 0.8V; when the intensity of the external wireless signal is in a medium level, the download speed of the mobile data network channel of the mobile terminal is limited to 0.5V, and when the intensity of the external wireless signal is in a high level, the download speed of the mobile data network channel of the mobile terminal is limited to 0, so that the download speed of the mobile data network channel of the mobile terminal is intelligently and dynamically adjusted according to the intensity of the external wireless signal.
Further, on the basis of the first embodiment of the network handover method of the present invention, a third embodiment of the network handover method is proposed, and in the third embodiment, after the step of opening the mobile data network channel of the mobile terminal, the method further includes:
step S50, counting the flow consumed by the mobile terminal through the mobile data network channel;
and step S60, when the flow consumed by statistics reaches a preset flow threshold, closing or limiting the mobile data network channel of the mobile terminal, and outputting preset prompt information.
After a mobile data network channel of a mobile terminal is opened, flow consumed by the mobile data network channel of the mobile terminal is counted, when the counted flow reaches a preset flow threshold (for example, 100M), it is indicated that a user consumes more flow by using a network behavior performed by the mobile terminal at the moment, the user needs to be reminded of paying attention, preset prompt information (the prompt information can be in one or more of voice, image, video and vibration) is output at the moment, the content of the prompt information can comprise the current residual flow of the user, the user is reminded of whether an application consuming large flow exists or not to carry out hidden operation, meanwhile, the mobile data network channel of the mobile terminal is closed or limited, and the phenomenon that the monthly consumed flow of the user exceeds the standard due to the fact that the mobile terminal consumes too much mobile network flow is prevented.
In addition, on the basis of the second embodiment of the network switching method of the present invention, after the step of opening the mobile data network channel of the mobile terminal, the method further includes:

As shown in fig. 9, a fourth embodiment of the data loading method based on multiple data channels according to the present invention is proposed, and the method includes the following steps:
and S11, establishing at least two threads for loading data according to the data loading instruction.
Specifically, when a user clicks a certain link, opens a certain page or downloads a certain file, the terminal receives a data loading instruction, immediately obtains the size of the data to be loaded, determines the number of threads for loading the data according to the size of the data to be loaded, the number of cores of a Central Processing Unit (CPU) of the terminal and the optimal thread support capacity, and establishes a corresponding number of threads to divide the data to be loaded into a plurality of data blocks, wherein each thread is responsible for loading one data block.
In some embodiments, the number of threads may also be preset according to the number of CPU cores of the terminal and the optimal thread support capability, and the terminal establishes a preset number of threads each time.
The number of CPU cores refers to the number of CPU processing cores, and includes single core, double core, and multiple cores. A multi-core CPU is equivalent to integrating multiple complete compute engines (i.e., cores) on one CPU, which share caches, memory, registers, etc.
Each program running on the system is a process, and the process can also be dynamic execution of the whole program or a part of the program, and each process comprises one or more threads. A thread is a collection of instructions, or a special piece of a program, that can be executed independently within the program. Threads are typically lightweight processes that are responsible for performing multiple tasks in a single program, and the operating system is typically responsible for scheduling and execution of multiple threads. Multithreading is to enable multiple threads to work in parallel to complete multiple tasks to improve the efficiency of the system, and threads are implemented when multiple tasks need to be completed at the same time.
And S12, allocating each thread to at least two data channels.
Specifically, the network quality of each data channel is dynamically detected, and then the threads are allocated according to the network quality, that is: more threads are allocated to the data channel with better network quality, fewer threads are allocated to the data channel with poorer network quality, and when the network quality of each data channel is equivalent, the data channels can be equally allocated. The detection of the network quality may adopt the existing detection method, and is not described herein again.
The data channel comprises a mobile network data channel of the SIM card and a WIFI network data channel of the wireless network card. The mobile network data channel may be a 2G network, a 3G network or a 4G network data channel, the 4G network data channel being an LTE network data channel. When the mobile terminal is a single-card terminal, the data channel comprises a mobile network data channel and a WIFI network data channel; when the mobile terminal is a dual-card terminal such as a DSDA terminal or even a multi-card terminal, one terminal can support two or more SIM cards, each SIM card corresponds to one radio frequency antenna, so that coexistence of two or more mobile networks can be realized, and at the moment, the data channel comprises a mobile network data channel of the two or more SIM cards, and a WIFI network data channel can be further included.
For example, the DSDA terminal establishes 4 threads to load data, and if the network quality of the first LTE network data channel of the first SIM card is better than that of the second LTE network data channel of the second SIM card, 3 threads are allocated to the first LTE network data channel, and 1 thread is allocated to the second LTE network data channel.
If the single-card terminal establishes 3 threads to load data, and the network quality of the WIFI network data channel of the wireless network card is better than that of the LTE network data channel of the SIM card, 2 threads are allocated to the WIFI network data channel, and 1 thread is allocated to the LTE network data channel.
In some embodiments, threads may also be evenly or randomly assigned to data channels.
And S13, establishing at least two transmission links by utilizing each thread through a corresponding data channel.
Specifically, the terminal establishes connection with the server through respective data channels by using each thread, and establishes a transmission link.
For example, assuming that 1 thread is allocated to the LTE network data channel of the first SIM card and 3 threads are allocated to the LTE network data channel of the second SIM card, the thread allocated to the LTE network data channel of the first SIM card establishes a connection with a server in which data to be loaded is located through the LTE network data channel of the first SIM card, sends a link establishment request, and establishes a transmission link; and 3 threads of the LTE network data channel distributed to the second SIM card are respectively connected with a server where the data to be loaded are located through the LTE network data channel of the second SIM card, a link establishment request is sent, and three transmission links are established.
And S14, downloading the data in blocks according to each transmission link.
Specifically, after receiving a link establishment request sent by each thread through each data channel, the server establishes a corresponding transmission link and transmits data blocks corresponding to each thread to the terminal along the transmission link, so that the terminal downloads data in blocks according to each transmission link, and the terminal collects and receives data returned by each thread and merges the data.
Further, in the data transmission process, when it is detected that one of the data channels has transmission abnormality (for example, data service loss occurs), the partial data which is not downloaded and is completely downloaded in the data block (or data packet) downloaded through the data channel is checked, a new thread is established in the other data channel, and the partial data which is not downloaded and is completely transmitted is started to be continuously transmitted at a breakpoint.
According to the data loading method based on the multiple data channels, the multiple threads are established, the threads are distributed to the two (or multiple) data channels, the multiple transmission links are established through the corresponding data channels by utilizing the threads, and the transmission links of the two (or multiple) data channels are used for downloading the same data in blocks, so that the data loading rate is greatly improved, and the internet surfing experience of a user is improved. And the decision right of the thread is distributed on the terminal side instead of the server side, so that the load of the server is reduced, and the flat design principle is met.
As shown in fig. 10, a fifth embodiment of the data loading method based on multiple data channels according to the present invention is proposed, and the method includes the following steps:
s21, establishing a first thread and a second thread for loading data according to the data loading instruction.

After receiving a data loading instruction, the terminal acquires the size of data to be loaded, and establishes 1 first thread and 2 second threads for loading the data, namely 3 threads are established in total, so as to divide the data to be loaded into 3 data blocks, and each thread is responsible for loading one data block.
And S22, allocating the first thread to the LTE network data channel of the SIM card, and allocating the second thread to the WIFI network data channel of the wireless network card.
Specifically, the terminal dynamically detects the network quality of the two data channels, and when the network quality of the WIFI network data channel is better than that of the LTE network data channel, 1 first thread is allocated to the LTE network data channel of the SIM card, and 2 second threads are allocated to the WIFI network data channel of the wireless network card.
And S23, establishing a first transmission link through the LTE network data channel by using the first thread, and establishing a second transmission link through the WIFI network data channel by using the second thread.
Specifically, the terminal establishes connection with a server through an LTE network data channel by using 1 first thread, and establishes a first transmission link; and establishing connection with the server through the WIFI network data channel by utilizing 2 second threads, and establishing 2 second transmission links.
And S24, downloading the data in blocks according to the first transmission link and the second transmission link.
Specifically, the server transmits the data block corresponding to the first thread to the terminal along the first transmission link, and transmits the data block corresponding to the second thread to the terminal along the second transmission link, so that the terminal downloads data in blocks according to the first transmission link and the second transmission link, and the terminal collects and receives data returned by the first thread and the second thread and combines the data.
Further, in the data transmission process, when it is detected that one of the data channels has transmission abnormality (for example, data service loss occurs), the partial data which is not downloaded in the data block (or data packet) downloaded through the data channel is checked, a new thread is established in the other data channel, and the partial data which is not downloaded is started to be continuously transmitted at the breakpoint.
In the data loading method based on multiple data channels, multiple threads are allocated to the mobile network data channel and the WIFI network data channel, multiple transmission links are established through the two data channels by utilizing the threads, and the same data is downloaded in blocks by using the transmission links of the mobile network data channel and the WIFI network data channel, so that a single-card terminal can use two networks to surf the internet simultaneously to improve the data loading rate, and the internet experience is improved.
As shown in fig. 11 and fig. 12, a sixth embodiment of the data loading method based on multiple data channels according to the present invention is proposed, where the method includes the following steps:
s31, establishing a first thread and a second thread for loading data according to the data loading instruction.
As shown in fig. 12, the mobile terminal of this embodiment is a DSDA terminal, and includes a first SIM card (hereinafter, referred to as a first card) and a second SIM card (hereinafter, referred to as a second card), after a user starts a dual-channel downloading function of the terminal, the terminal simultaneously starts a mobile network of the first card and a mobile network of the second card, and establishes a first network connection and a second network connection respectively. The mobile network of the card one forms a card one data channel, the mobile network of the card two forms a card two data channel, and the mobile networks of the card one and the card two can be 2G, 3G or 4G (such as LTE) networks.
When a user clicks a download file, the terminal receives a data loading instruction, obtains the size of the download file, specifies the number of threads required by the download file, and establishes a first thread and a second thread with corresponding numbers.
And S32, allocating the first thread to the card-one data channel and allocating the second thread to the card-two data channel.
Specifically, as shown in fig. 12, the terminal performs dual-channel link quality measurement according to a link measurement algorithm, and performs dual-channel thread allocation through a measurement report, that is: and respectively detecting the network quality of the first card data channel and the second card data channel, and distributing more threads for the data channel with better network quality.
For example, assuming that the network quality of the card-one data channel is better than that of the card-two data channel, 3 first threads and 1 second thread, 3 first threads are allocated to the card-one data channel and 1 second thread is allocated to the card-two data channel.
S33, establishing a first transmission link over the card-to-data channel using the first thread, and establishing a second transmission link over the card-to-data channel using the second thread.
Specifically, as shown in fig. 12, the terminal establishes a first transmission link through the card-data channel by using the card-data channel thread (i.e., the first thread allocated to the card-data channel), and sends a link download request to the server to request to download the first data packet of the file; establishing a second transmission link through the card-two data channel by using the card-two data channel thread (i.e., the second thread assigned to the card-two data channel), and sending a link download request to the server for downloading a second data packet of the file.
And S34, downloading the data in blocks according to the first transmission link and the second transmission link.
Specifically, as shown in fig. 12, the terminal starts a thread according to a thread request and performs data transmission: the first data packet P1 is transmitted according to a first transmission link of the card-one data channel, and the second data packet P2 is transmitted according to a second transmission link of the card-two data channel. And finally, unpacking and combining the data packets after the dual-channel downloading is finished to obtain the data packet M of the whole downloaded file.
Further, in the data transmission process, the terminal monitors channels of the two data channel nodes of the card-in-card to process the exception in real time. If the loss of the card-two data service is monitored, the partial data P3 that is not downloaded and completed in the second data packet P2 is checked, a new thread is established in the card-one data channel to start the breakpoint transmission, and the partial data P3 that is not downloaded and completed is downloaded.
