DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] To enable those skilled in the art to better understand the technical solutions of this application, the embodiments of this application will be further described in detail below with reference to the drawings.

[0040] It is understood that without conflict, the functions and steps marked in the flowcharts and block diagrams of the present application may occur in an order different from that marked in the drawings.

[0041] It is understood that in the flowcharts and block diagrams of the present application, the possible architectures, functions, and operations of the systems, devices, equipment, and methods according to the various embodiments of the present application are shown. Among them, each block in the flowchart or block diagram may represent a unit, module, program segment, or code, which contains executable instructions for implementing the specified function. Moreover, each block or combination of blocks in the block diagram and flowchart may be implemented by a hardware-based system for implementing the specified function, or by a combination of hardware and computer instructions.

[0042] It is understood that the units and modules involved in the embodiments of the present application may be implemented in software or in hardware. For example, the units and modules may be located in the processor.

[0043] Current situation of 5G terminals:

[0044] 1) Most of the existing 5G terminals are single 5G-channel devices, that is, they only have one 5G module. Whether one SIM card or two SIM cards are inserted, ultimately only one SIM card communicates with the network side through the 5G module at the same time, and this naturally does not have the dual-channel protection ability.

[0045] 2) Some of the existing 5G terminals have the ability to communicate with the network side through the 5G module and the wired interface respectively. The two communication interfaces have protection functions, but they cannot communicate simultaneously.

[0046] 3) Very few 5G terminals are equipped with dual 5G modules, but the two channels can only work independently and it is difficult to achieve advanced collaborative work. Such terminals cannot detect the communication quality of the entire channel from the two 5G channels to the peer in real time. They can only configure communication strategies in the default way that both channels are normal, and cannot implement advanced strategies such as dual-transmission mode and real-time mode. The bandwidth utilization rate is not as high as that in the aggregation mode when the two channels work simultaneously. Since there is no way to detect the communication quality of the entire end-to-end link, it is difficult to optimize the network communication effect when facing applications with low latency, weak network communication, and the need to smooth network jitter.

[0047] In real-world 5G communications, the following situations often occur and urgent solutions are needed:

[0048] 1) In the case of a weak network, both the communication bandwidth and communication quality are severely affected, and the communication quality of existing 5G terminals is very poor under weak network conditions.

[0049] 2) Operators will limit the maximum bandwidth of a single 5G channel. Large-bandwidth applications such as 5G high-definition live broadcasts will be affected by the single-channel bandwidth and cannot achieve satisfactory results. Even for devices with ordinary multi-5G modules, due to the lack of an effective scheduling strategy between multiple channels in the system, a good channel aggregation effect cannot be achieved.

[0050] 3) Applications such as 5G factories, 5G surgeries, and 5G remote controls have extremely high requirements for the real-time performance and reliability of the 5G network. Single-channel 5G terminals or devices with ordinary multi-5G modules are difficult to meet the requirements.

[0051] 4) The network coverage and optimization of the three major operators are different. In a mobile scenario, when multi-5G module devices use multiple operator networks, the handover process often causes service interruptions and affects normal use.

[0052] Based on the above problems, this application proposes a 5G network dual-channel transmission system. Through a systematic solution, compared with the prior art, the following problems can be solved:

[0053] 1) According to the application scenario, the dual-channel 5G terminal can be configured for communication in dual-transmission mode, real-time mode, aggregation mode, etc., to meet the requirements of high reliability, large bandwidth, high real-time performance, etc. respectively.

[0054] 2) The two 5G channels of the dual-channel 5G terminal can use 5G networks of the same operator or different operators.

[0055] 3) Improve the dual-channel aggregation efficiency, reduce overhead, and improve the capacity after aggregation through precise scheduling of traffic on each channel.

[0056] 4) Optimize network latency, reduce the latency introduced by functions such as dual-transmission and retransmission, and smooth latency jitter.

[0057] 5) Improve the stability in weak network environments. When the network changes rapidly, it can respond quickly to ensure stable network performance, continuous network connection, and no drop in speed.

[0058] 6) Provide precise service guarantee. It can guarantee the reliability of specified service traffic and reduce the user traffic cost; the service application is transparent, and customers do not need to modify the application.

[0059] The following uses specific embodiments to elaborate in detail on the technical solutions of this application and how the technical solutions of this application solve the above technical problems. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0060] Figure 1 It is a schematic diagram of a 5G network dual-channel transmission system provided by an embodiment of this application, as Figure 1 shown. This application provides a 5G network dual-channel transmission system, and the system includes:

[0061] Dual-channel 5G terminals (equipped with 2 5G modules), running client application software APP, and provided with a first 5G transmission channel and a second 5G transmission channel to implement different dual-channel modes;

[0062] Dual-channel gateway server, running server-side software, used to evaluate and schedule the data transmission mode of the dual-channel 5G terminal in real time according to network quality;

[0063] Console, used to control and manage the dual-channel gateway server and the dual-channel 5G terminal.

[0064] In this application, the number of dual-channel 5G terminals can be multiple. When there are multiple dual-channel 5G terminals, the structure between the dual-channel gateway server and the dual-channel 5G terminals is a point-to-multipoint structure. For ease of explanation, Figure 1 only one dual-channel 5G terminal is taken as an example for elaboration.

[0065] In this application, the dual-channel gateway server can be a physical host or a virtual host on the cloud.

[0066] Among them, a physical host refers to the physical server hardware, which has independent components such as a CPU, memory, and hard disk. It can provide high-performance and low-latency data processing capabilities and can be upgraded and expanded according to requirements. Physical hosts have the advantages of stable performance, being unaffected by the virtualization layer, exclusive hardware resources, avoiding resource competition, being easy to manage and maintain, and more direct fault troubleshooting. They can be adapted to scenarios with extremely high requirements for data transmission speed and stability in large enterprises or data centers, or scenarios that require independent management and control of hardware resources.

[0067] Among them, a virtual host on the cloud refers to a virtual server created on a cloud computing platform, sharing the resources of a physical host, featuring elastic scaling and pay-as-you-go, and enabling rapid deployment and expansion. The virtual host on the cloud has advantages such as low cost, pay-as-you-go, avoiding waste of idle resources, elastic scaling, being able to quickly adjust resource configuration according to needs, being highly flexible, easy to manage and maintain, etc., and can be adapted to cost-sensitive scenarios such as small and medium-sized enterprises or start-up companies, or scenarios that require rapid deployment and expansion of server resources, or applications with not extremely high requirements for data transmission speed and stability.

[0068] In this application, the dual-channel 5G terminal runs client software and communicates with the server software running on the dual-channel gateway server. The dual-channel gateway server ensures network stability, reliability, and real-time performance by scheduling the data transmission mode through real-time evaluation of network quality.

[0069] In this application, the console can be deployed in the cloud or locally to control and manage the dual-channel gateway server and the dual-channel 5G terminal. The functions include a multi-channel acceleration software development kit (SDK) and gateway authentication, scheduling control, gateway operation and maintenance monitoring, system operation support, etc.

[0070] Among them, the multi-channel acceleration software development kit (SDK) is a set of toolkits provided to developers for implementing multi-channel acceleration functions on the dual-channel gateway server and the dual-channel 5G terminal. Through the SDK, developers can easily integrate multi-channel acceleration technology into their own applications to improve the rate and stability of data transmission. The SDK usually includes API interfaces, development documents, sample codes, etc., which are convenient for developers to get started and use quickly.

[0071] Among them, gateway authentication ensures that only legitimate users and devices can access the dual-channel gateway server. Through various authentication methods such as user names, passwords, and certificates, the identity of users or devices attempting to connect to the gateway is verified. This process can effectively prevent unauthorized access and ensure network security.

[0072] Among them, scheduling control can reasonably allocate and schedule the resources of the dual-channel gateway server and the dual-channel 5G terminal. According to factors such as network load and user requirements, dynamically adjust the resource allocation of the server and the terminal, such as bandwidth, CPU, memory, etc., to achieve optimal performance and efficiency.

[0073] Among them, gateway operation and maintenance monitoring performs real-time monitoring and management on the operating status of the dual-channel gateway server. The operating data of the gateway, such as CPU usage, memory occupancy, network traffic, etc., is collected in real time through monitoring tools, and these data are analyzed and displayed. Once an abnormal situation is detected, an alarm can be issued in a timely manner and corresponding measures can be taken to ensure the stable operation of the gateway.

[0074] Among them, system operation support provides comprehensive support for the operation of the dual-channel gateway server and the dual-channel 5G terminal. The functions include user management, billing management, log management, report generation, etc. Through these functions, the operator can conveniently manage users and devices, record and analyze operation data, and generate various reports for decision-making reference.

[0075] In some embodiments, the dual-channel mode of the dual-channel 5G terminal includes a dual-transmission mode, a real-time mode, and an aggregation mode.

[0076] This application faces different business scenario requirements, makes full use of the dual 5G module access resources of the 5G dual-channel gateway, adapts to three dual-channel modes: dual-transmission mode, real-time mode, and aggregation mode, and realizes greater bandwidth and lower latency.

[0077] In some embodiments, the dual-transmission mode is: the dual-channel 5G terminal transmits the same communication content through the first 5G transmission channel and the second 5G transmission channel; the dual-channel gateway server selects the channel with the optimal parameters from the first 5G transmission channel and the second 5G transmission channel according to the wireless communication parameters for data transmission.

[0078] Specifically, in the dual-transmission mode, both the first 5G transmission channel and the second 5G transmission channel transmit the same content. On the dual-channel gateway server, according to the statistical information, the channel with the best jitter and latency indicators within the statistical period is selected as the selected channel, and its load is transmitted. In this mode, both dual channels can run at full load, using double 5G traffic. It is applicable to high-reliability dual-channel protection scenarios.

[0079] In some embodiments, the real-time mode is:

[0080] The dual-channel 5G terminal obtains the performance parameters of the first 5G transmission channel and the second 5G transmission channel, and selects the channel with the optimal parameters from the first 5G transmission channel and the second 5G transmission channel for data transmission.

[0081] Specifically, in the real-time mode, only the better-performing one of the first 5G transmission channel and the second 5G transmission channel is used for transmission at the same moment. For example, the first 5G transmission channel is used from time t0 to t3, the second 5G transmission channel is used from time t4 to t8, and the first 5G transmission channel is used from time t9 to t10, and so on. In this mode, only 1 portion of 5G traffic is cumulatively used on the dual channels, and the optimal channel can be selected for transmission in real time at a lower cost. In this mode, the statistical period used for link monitoring is shorter to ensure the timeliness of channel switching.

[0082] In some embodiments, the aggregation mode is as follows: the dual-channel 5G terminal assigns different communication contents to the first 5G transmission channel and the second 5G transmission channel respectively according to the network conditions, and simultaneously transmits the corresponding assigned communication contents through the first 5G transmission channel and the second 5G transmission channel.

[0083] Specifically, in the aggregation mode, different arranged contents are simultaneously transmitted through the first 5G transmission channel and the second 5G transmission channel. In the case where the bandwidth of a single channel is limited, an effect close to the sum of the bandwidth of channel 1 and the bandwidth of channel 2 can be achieved. It is applicable to the transmission service when exceeding the bandwidth upper limit of a single 5G channel, or to improve the transmission bandwidth and service stability in a weak network situation.

[0084] In some embodiments, the dual-channel gateway server is further configured to be responsible for the message forwarding process of the dual-channel 5G terminal, specifically including:

[0085] Intercept and terminate the Transmission Control Protocol (TCP) / User Datagram Protocol (UDP) connection of the dual-channel 5G terminal APP;

[0086] Use the Multipath Quick UDP Internet Connections (mpquic) to multiplex and transmit user data;

[0087] The acceleration gateway in the dual-channel gateway server simulates the APP to initiate a new TCP / UDP connection to the source station and forward the message.

[0088] Figure 2 This is a schematic diagram of the working principle of the dual-channel transmission system in the embodiments of the present application. As Figure 2 shown, the message forwarding process mainly includes:

[0089] 1) Intercept and terminate the tcp / udp connection of the APP at stage T0;

[0090] The dual-channel gateway server intercepts the original TCP / UDP connections initiated by the APP, terminates the original connections, and takes over the data traffic into the transmission channels controlled by the gateway, preparing for subsequent multi-path transmission (MPQUIC) and acceleration processing.

[0091] 2) Use mpquic multi-path transmission for the user data payload in the T1 stage;

[0092] The dual-channel gateway server encapsulates the original TCP / UDP data into the QUIC protocol and transmits it in parallel through multiple paths.

[0093] 3) Accelerate the gateway to simulate the APP to initiate a new tcp / udp connection to the source station and forward the packets in the T2 stage.

[0094] The acceleration gateway simulates the APP behavior and initiates a new TCP / UDP connection to the target source station (such as a cloud server). Restore the data transmitted through the QUIC tunnel in the T1 stage to the original protocol format (TCP / UDP) and forward it to the source station. Achieve end-to-end transparent transmission, and the source station does not need to perceive the intermediate multi-path acceleration process.

[0095] This application uses the process of interception-encapsulation-multi-path transmission-protocol restoration, utilizes MPQUIC and dual-channel network to improve the transmission efficiency, and at the same time centrally realizes scheduling and congestion control by the gateway to ensure stability and low latency.

[0096] In some embodiments, the dual-channel gateway server is used to determine the data transmission mode of the dual-channel 5G terminal through a multi-path scheduling algorithm, and the scheduling algorithm includes at least one of Low Round-Trip Time First - Check Latest Round-Trip Time (LowRTT-checkLatestRTT), Explicit Congestion Feedback Algorithm (ECF), and Blocking Estimation Scheduling Algorithm (BLEST).

[0097] Reference Figure 2 , this application's multi-path scheduling adopts three scheduling algorithms: LowRTT-checkLatestRTT, ECF, and BLEST. LowRTT is used as the default algorithm, which has the best anti-jitter effect and better performance in a weak network environment.

[0098] LowRTT-checkLatestRTT preferentially considers the path with the lowest latency in the way of RTT (Round-Trip Time), and at the same time evaluates the instantaneous latency of the link packet by packet and the smoothed latency in the recent period. Based on these parameters, comprehensively judge whether the link is suitable for transmitting packets to achieve the best anti-jitter goal and adapt to the cellular network scenario with particularly fast changes.

[0099] In some embodiments, the dual-channel gateway server is used to optimize transmission by adopting the BBRv1 congestion control algorithm.

[0100] In some embodiments, the specific steps for the dual-channel gateway server to adopt the BBRv1 congestion control algorithm include:

[0101] Gradually increase the sending rate to gradually fill the link bandwidth;

[0102] Reduce the sending rate to release the packets cached in the link buffer;

[0103] Periodically detect the maximum bandwidth of the link to make the current sending rate match the best operating point of the link's bandwidth-delay product (BDP).

[0104] Specifically, the present application adopts the BBRv1 congestion control algorithm, and the specific implementation is as follows:

[0105] 1) Gradually increase the sending rate to gradually fill the link bandwidth. At the same time, monitor the RTT of the link. When the RTT continuously increases, it indicates that the link bandwidth has reached the bottleneck;

[0106] 2) Reduce the sending rate to release the packets previously cached in the link buffer;

[0107] 3) Periodically detect the maximum bandwidth of the link to always make the current sending rate match the best BDP operating point of the link. When BBR detects that the RTT of the link has not been updated for a period of time, it will also enter the probeRTT state. In this stage, BBR will significantly reduce the speed to quickly consume the link buffer, so that BBR can detect the accurate RTT of the link.

[0108] The present application provides a 5G network dual-channel transmission system, which is applicable to the protection and optimization of dual-channel transmission in the 5G network. Among them, the dual-channel 5G terminal runs client software and communicates with the server-side software running on the dual-channel gateway server. The dual-channel gateway server schedules the data transmission mode by real-time evaluation of the network quality. The console controls and manages the dual-channel 5G terminal and the dual-channel gateway server. As an overall system, the three can achieve various different modes of communication for 5G dual channels, ensuring network stability, reliability, large bandwidth, and high real-time performance.

[0109] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present application. However, the present application is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present application, and these modifications and improvements are also regarded as the protection scope of the present application.
