Wireless network transmission method and system

The present invention relates to a wireless network transmission method and system, which is a technology for simultaneous uploading or downloading in an environment in which a plurality of wireless networks cover overlapping environments. Specifically, it refers to the processing of file transmission on the Internet Service Provider (ISP) side, so that the terminal can simultaneously upload or download simultaneously using a plurality of wireless networks. The design of the present invention can be applied to Internet application services, especially cloud application services.

Traditional wireless network transmission uses only a single wireless communication system to transmit data, so the speed of data transmission depends solely on the technical specifications and transmission capabilities of the wireless communication system. For example, 3G WCDMA downlink maximum rate is 2Mbps, 3.5G DC-HSPA+ downlink maximum rate is 42Mbps, 3.9G LTE 20MHz bandwidth downlink maximum rate is 150Mbps, 4G LTE-A Category 8 downlink maximum rate is 3Gbps, Wi-Fi 802.11 Ac wave 2 has a maximum rate of 3.5 Gbps, and so on. In view of the large data volume transmission demand brought by the increasingly rich and high-quality multimedia materials, the network capacity and transmission rate need to be continuously improved. Techniques for increasing network capacity and transmission rate can be divided into the following three directions:

1. Increase the network bandwidth: for example, the mobile network bandwidth is increased from 5MHz in 3G to 10MHz in 3.5G DC-HSPA+, and then increased from 10MHz in 3.5G DC-HSPA+ to 3.9G LTE 20MHz, and then 3.9G LTE 20MHz. Upgrade to 100MHz for 4G LTE-A Category 8. As a result of the increase in bandwidth, the transmission rate is proportionally increased.

2. Improve system spectral efficiency: The increase in spectrum efficiency is mainly through the introduction of new technologies. For example, the third-generation mobile network has a maximum spectral efficiency of 0.4 bit/sec/Hz, and the 3.5-generation mobile network has a maximum spectral efficiency of 4.2 bit/sec/ The highest spectral efficiency of the Hz, 3.9 generation mobile network is 7.5 bit/sec/Hz, and the highest spectrum efficiency of the 4th generation mobile network is 30 bit/sec/Hz.

3. Increase the density of station construction or build small cells: Since radio resources are of a shared nature, the fewer people you share, the more air time, frequency and space resources are available, and the transmission rate is The faster you can. This effect can be achieved by increasing the density of the platform or building small cells.

Among the above three technical directions of increasing network capacity and transmission rate, the method of increasing the network bandwidth is the simplest and the effect is most directly significant. The wireless network transmission method and system proposed by the present invention is to increase the transmission rate of the terminal by adopting the first direction of increasing the network bandwidth.

A similar concept is mentioned in the US patent "Leveraging multiple access technologies simultaneous (US20130322347 A1)", which is a core network solution that uses a special enhanced packet data gateway (ePDG) to import Wi-Fi traffic into the mobile network. The road integrates Wi-Fi and mobile network services into the core network to achieve the added value, but does not provide the same terminal to use the mobile network and Wi-Fi technology while accessing the network. Another similar concept is mentioned in the US Patent "System and method for heterogeneous carrier aggregation (US20130242897)", which can simultaneously access mobile networks and Wi-Fi and transmit, but distribute different in the internet protocol (IP) layer. The application service data transmission, so the communication protocol needs to be modified to achieve the effect of simultaneously accessing different wireless networks, and the complexity is high and its function is not for the accelerated application of a single file.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventors of the present invention have improved and innovated, and after years of painstaking research, they finally succeeded in researching and developing the method and system for transmitting the wireless network.

The object of the present invention is to provide a wireless network transmission method and system, which is a technology for simultaneous uploading or downloading in an environment in which a plurality of wireless networks cover overlapping areas. When users need to transmit or receive files, they can open multiple wireless transmission air intermediaries and transmit or receive them through multiple wireless network technologies, which can speed up the file transmission speed and shorten the user's waiting time.

The second purpose of the present invention is to further design an application layer transmission protocol conversion mechanism as a relay mechanism between uploading and downloading services and different network services, ensuring the normal operation of uploading or downloading services at the same time, and applying the application. The layer's redundancy control byte is controlled to a minimum.

The plurality of wireless transmission modules and the corresponding wireless network are in a one-to-one correspondence. On the network side, the network application layer transmission protocol conversion module receives data sent from a plurality of wireless networks, and performs related conversion according to an application layer transmission protocol of the subsequent network service. After the data is reorganized, the complete data can be transmitted to the receiving end of the network service. Since the transmission of the complete file is located at the core of the network, it is generally connected through fiber, so its delay can be ignored. Internet services can include audio and video services, audio and video sharing, social networking sites, cloud hard drives or application downloads.

The wireless network terminal receiving method for achieving the above object is to first cut a file to be transmitted into a plurality of chips on the network side, so as to facilitate subsequent distribution to a plurality of wireless networks for simultaneous transmission. Then, according to the characteristics of the file, the network end application layer network transmission protocol is set to ensure the quality of the transmission service. After the application layer network transmission protocol of the file is determined, a plurality of chips can be allocated to the wireless network for simultaneous data transmission.

The present invention relates to a wireless network transmission method and system, which is a technology for simultaneous uploading or downloading in an environment in which a plurality of wireless networks cover overlapping environments. The invention specifically refers to the network The service provider performs the file transmission process. When the user needs to transmit or receive the file, the user can open a plurality of wireless transmission null mediation planes, and cut the file to be uploaded or downloaded into a plurality of chips on the network side, and then The transmission and reception through multiple wireless networks can improve the speed of file transfer and shorten the waiting time of users. The invention further designs a conversion mechanism of the application layer transmission protocol, as a relay mechanism between the uploading and downloading services and different network services, ensuring the normal operation of uploading or downloading services at the same time, and the redundancy control of the application layer The byte is controlled to the smallest extent. In the present invention, a plurality of wireless transmission modules and a corresponding wireless network belong to a one-to-one correspondence. On the network side, the radical network application layer transmission protocol conversion module receives data sent from a plurality of wireless networks, and performs related conversion according to an application layer transmission protocol of a subsequent network service. After the data is reorganized, the complete data can be transmitted to the receiving end of the network service. Since the transmission of the complete file is located at the core of the network, it is generally connected through fiber, so its delay can be ignored.

Please refer to FIG. 1 , which is a structural diagram of a wireless network transmission system according to the present invention, including a terminal file cutting and reorganization module 101 , a terminal application layer transmission protocol setting module 102 , and a terminal aggressive transmission control module 103 . a plurality of wireless communication modules 104, a plurality of wireless networks 105, a network-side application layer transmission protocol conversion module 106, a network-side radical transmission control module 107, and a network-side file cutting and reorganization module 108, and a network service 109. The terminal file cutting and reorganizing module 101, the terminal application layer transmission protocol setting module 102, the terminal aggressive transmission control module 103 and the wireless communication module 104 belong to the terminal device, and the wireless network 105 and the network application layer transfer protocol The conversion module 106, the network-side radical transmission control module 107, the network-side file-removal and reassembly module 108, and the network service 109 belong to a network-side device, and the network service 109 includes audio-visual services, audio-visual sharing, and social networking sites. , the cloud hard drive or the application download, and the network service 109 is used for both the terminal and the network side of the network service.

When the terminal performs file uploading, the terminal file cutting and reorganizing module 101 cuts the file to be uploaded into M segments. 2 is a schematic view of the file cutting proposed by the present invention. For example, a 1000MB file can be cut into 50 segments, each with a size of 20MB. The terminal file cutting and reorganizing module 101 transmits the file information to the network, such as the size of the file, the size of the segment, the location of the segment, and the like. Next, the terminal application layer transmission protocol setting module 102 sets the transmission format of the application layer according to the characteristics of the file. Possible application layer transmission protocols include http, https, ftp, rtsp, and the like. For example, small file transfer can use http application layer transport protocol, large file transfer can use ftp application layer transport protocol, confidential file transfer can use https application layer transport protocol, video stream file transfer can use rtsp application layer transport protocol. At the same time, according to the control signaling of the terminal aggressive transmission control module 103, the M segments are distributed to the N available wireless communication modules 104 and the wireless network 105 according to the aggressive principle. The terminal aggressive transmission control module also transmits the account password required by the user to send the file to the network transmission protocol control module. The data from the N wireless networks 105 is sent to the network application layer transmission protocol conversion module 106 on the network side, and then the necessary transmission protocol conversion is performed according to the application layer transmission protocol used by the network service 109. For example, the cloud hard disk network service generally adopts the https application layer transmission protocol, so it may be necessary to convert the http between the terminal and the network application layer transfer protocol conversion module 106 into https, or the terminal and the network application layer. The ftp between the transport protocol conversion modules 106 is converted to https. For example, the social networking service of the social networking site generally adopts the http application layer transmission protocol, so it may be necessary to convert the https between the terminal and the network application layer transmission protocol conversion module 106 into http, or the terminal and the network application layer. The ftp between the transport protocol conversion modules 106 is converted to http. Through the design of the network-side application layer transport protocol conversion module 106, a variety of different application services can be accessed at a high speed by using a single network service portal. Next, in the network side file cutting and reorganizing module 108, the data from the N wireless networks 105 is reorganized and restored to the original file. Finally, the network side file reorganization module 108 transmits the file to the network service 109. The web service 109 can include a cloud hard drive Services (such as Google Drive), social networking services (such as Facebook), video sharing network services (such as YouTube). Regarding the N wireless network 105 registration and user identity authentication portions, the existing technologies of the individual networks are employed. For example, the LTE network performs EPS (Evolved Packet System) AKA (Authentication and Key Agreement) authentication through exchange of four parameters (RAND, AUTN, XRES, KASME). Regarding the network service 109 user identity authentication part, the conventional OAuth (Open Authentication) 2.0 open authorization technology is adopted.

When the terminal performs file downloading, the network file deletion and reassembly module 108 obtains the file to be downloaded by the terminal from the network service 109 through the application layer transmission format specified by the service, and cuts the file into M segments. For example, a 1000MB file can be cut into 50 segments, each with a size of 20MB. The network side file cutting and reorganizing module 108 transmits the file information to the terminal, such as the size of the file, the size of the segment, the location of the segment, and the like. Next, the network-side application layer transport protocol conversion module 106 converts the application layer transport format from the network service 109 according to the characteristics of the archive. Possible application layer transport protocols include http, https, ftp, rtsp, etc. For example, small file transfer can use http application layer transport protocol, large file transfer can use ftp application layer transport protocol, confidential file transfer can use https application layer transport protocol, Video streaming file transfers can be transferred using the rtsp application layer. The network application layer transmission protocol conversion module 106 and the terminal application layer transmission protocol setting module 102 jointly set a transmission protocol. For example, the cloud hard disk network service generally adopts the https application layer transmission protocol, so the terminal and the network application can be applied. The https between the layer transport protocol conversion modules 106 is converted to http. At the same time, according to the control signaling of the network-side aggressive transmission control module 107, the M-segments are allocated to the N available wireless networks 105 according to the principle of radical. Another function of the network-side aggressive transmission control module is to transmit the account password required by the user to send the file to the network server. The data from the N wireless networks 105 is sent to the N wireless communication modules 104 at the terminal. most After that, the terminal file cutting and reorganizing module 101 reorganizes the data from the N wireless networks 105 and restores the original file to complete the file downloading operation.

FIG. 3 is a schematic file transmission method proposed by the present invention. First, the terminal aggressive transmission control module analyzes a plurality of wireless networks to find available wireless network N (S01). The method of analysis can be determined by the way in which the certification can be successfully completed. Next, it is judged whether the terminal is to transmit or receive the file. If the terminal wants to transmit the file, the network-side aggressive transmission control module retrieves the transmission file information from the terminal (S02). The file information includes file type, size, upload location, and so on. Next, the terminal file cutting and recombining module cuts the file to be transmitted into M aliquots (S03), and each aliquot is called a chip. The size of a chip can be cut according to the type of the file. For example, the block length of the video stream file can be less than 1 Mbyte, and the block length of the non-video stream file block is greater than 1 Mbyte. Then, the segments cut into M aliquot files are sequentially assigned to N available network transmissions (S04), as illustrated in FIG. Next, the processed segment is allocated to the idle network that has completed the chip transmission (S05), and is performed by first performing the first allocation. If there is still a segment that has not been assigned, the above steps are continued, and if all the segments have been assigned, the process proceeds to the next step (S06). The average transmission rate analysis (S07) of the wireless network N is performed by the terminal aggressive transmission control module or the network-side radical transmission control module, and the analysis includes that the last assigned chip transmission network has been completed and the last is not completed. There are two types of chip transmission networks that are allocated. If Ri represents the rate at which the last transmitted chip transmission network has been completed, and Si represents the rate at which the last transmitted chip transmission network is not completed, their calculations are as follows:

Where L represents the length of the chip, Ui represents the download time of Ri, Nx represents the number of transmission networks that have completed the last assigned chip, L _Vi represents the chip length of the i-th unfinished final transmission work, and Vi represents the download. time. Next, the terminal aggressive transmission control module or the network-side radical transmission control module checks whether there is a low-speed network (S08), and the check inequality is as follows:

Among them, 0 α 1 represents an adjustable control parameter. If the S _i conforms to the formula (2), there is a low-speed network, and the terminal-driven transmission control module or the network-side radical transmission control module simultaneously allocates the low-speed network segment to the idle wireless network R _{i .} (S09). At this time, the networks represented by S _i and R _i will simultaneously download the same segment. If the two network conditions remain the same, the network represented by R _i will complete the download of this segment first. In this case, the network download work represented by S _i will be terminated.

In addition, if the terminal wants to receive the file, the network file deletion and reassembly module retrieves the received file information from the network (S10). The file information includes file type, size, upload location, and so on. Next, the network side file cutting and recombining module cuts the file into M segments (S11), and the terminal sequentially receives the M segments from the N network (S12). The segment control in the whole transmission process is the same as that in the terminal transmission file. The difference is that the control point is the network end. Finally, the terminal file cutting and reorganizing module reorganizes the M file segments from the N wireless networks and restores them into the original file (S13), completing the entire file receiving operation.

FIG. 5 is a schematic diagram of a radical file transfer process proposed by the present invention. Suppose the transfer file is cut into 5 chips and assumes that there are currently two available networks, including LTE and Wi-Fi. We further assume that the time for LTE to transmit one chip is 2 seconds, and the time for Wi-Fi to transmit one chip is 5 seconds. According to the aggressive file transfer method proposed by the present invention, chips 1 and 2 are respectively assigned to LTE and Wi-Fi transmission. At 2 seconds, LTE completes the transmission of chip 1, so chip 3 is assigned to LTE transmission. At 4 seconds, LTE completes the transmission of chip 3, so chip 4 is assigned to LTE transmission. At 5 seconds, Wi-Fi completes the transfer of chip 2, so chip5 is assigned to Wi-Fi transmission. At 6 seconds, LTE completes the transfer of chip 4. If α of the formula (2) is >0.5, Wi-Fi belongs to a low-speed network. At this point, chip5 is also assigned to LTE transmission at the same time. Finally, LTE completes the transfer of chip 5 at 8 seconds. At this time, Wi-Fi's chip 5 only finished 0.6. According to the aggressive file transfer method proposed by the present invention, the Wi-Fi chip 5 transmission operation is terminated, and the simultaneous download of LTE and Wi-Fi is completed. As can be seen from the above example, it takes 25 seconds to transmit only with Wi-Fi, 10 seconds for LTE transmission, and 10 seconds for LTE plus Wi-Fi but without this method. LTE plus Wi-Fi and using this method only takes 8 seconds.

If the terminal wants to receive the file, it will receive the file information from the network. The file information includes file type, size, upload location, and so on. Next, the network divides the file into M segments and the terminal receives the M segments sequentially from the N network. The segment control in the whole transmission process is the same as that in the terminal transmission file. The difference is that the control point is the network end. Finally, the M file fragments that have been successfully received are reorganized to complete the action of receiving the entire file.

FIG. 6 is another aggressive file transmission method according to the present invention. The difference from FIG. 3 is that the terminal transmission mechanism is controlled by the network, and the terminal reception mechanism is controlled by the terminal. FIG. 7 is another aggressive file transmission method proposed by the present invention. The difference from FIG. 3 is that the terminal transmission and reception mechanisms are determined by the terminal.

The wireless network transmission system and method provided by the invention simultaneously utilizes a plurality of heterogeneous wireless networks for file transmission to increase the speed of data uploading and downloading, and the terminal can allocate each network file according to the state of the heterogeneous wireless network.
