If the aggregation server and the server corresponding to the destination are not in the same network consisting of a plurality of servers, the data can be forwarded to the server corresponding to the destination through the network in which the aggregation server is located.

The scheme of the present application is explained below by means of a specific method flow.

Fig. 2A is a schematic flowchart of a data transmission method according to an embodiment of the present application, where the method may be applied to the network access device, and as shown in the figure, the method includes:

s201, determining the aggregation server with the distance to the network access equipment within a preset distance range, and establishing an aggregation link between the aggregation server and the network access equipment.

The network access device includes a plurality of mobile communication modules accessing communication networks of different communication service providers, and the aggregated link includes sub-communication links established based on the communication networks of the different communication service providers.

In this embodiment, the communication service provider may be, for example, mobile, connected, telecommunication, etc., and the communication network of the communication service provider may be a mobile signal provided by mobile, connected, telecommunication.

In this embodiment, the network access device may include a plurality of mobile communication modules, and SIM cards of different communication service providers may be inserted into the plurality of mobile communication modules, so that communication networks of different communication service providers may be accessed through the plurality of mobile communication modules. In addition, the plurality of mobile communication modules may include a 4G, 5G communication module, such that the sub-communication link may be established through a 4G or 5G network provided by a communication service provider. The mobile communication module can access a communication network of a communication service provider and then establish a sub-communication link with the aggregation server through the communication network, wherein the aggregation link comprises a plurality of sub-communication links.

In this embodiment, the aggregation server whose distance from the network access device is within a preset distance range may be acquired according to the geographical location information of the network access device, and an aggregation link with the aggregation server may be established.

S202, distributing data to be sent according to the communication parameters of the sub communication links, and sending distributed partial data to the aggregation server through a plurality of sub communication links of the aggregation link respectively.

In this embodiment, the communication parameters of the sub communication link may be used to characterize the capability of the sub communication link to transmit data, and the communication parameters may include parameters such as bandwidth, transmission rate, signal quality, and signal strength. In this embodiment, based on the communication parameters, data to be sent can be flexibly allocated to the plurality of communication sublinks according to the data transmission capability represented by the communication parameters, so that the communication sublinks respectively send part of the data to the aggregation server.

Optionally, step S202 may include: determining data quantity shares of the data to be sent, which can be respectively sent by a plurality of the sub communication links, according to communication parameters of the plurality of the sub communication links; and performing data transmission allocation on the data to be transmitted according to the determined data volume share, so as to respectively transmit the allocated data to be transmitted to the aggregation server through a plurality of sub communication links in the aggregation link according to the respective corresponding data volume shares.

In this embodiment, the capability of the sub-communication links to transmit data may be determined according to the communication parameters of the sub-communication links, and the data volume share of the data to be transmitted may be determined according to the capability. The data volume share may be a proportion of the data volume transmitted via the sub-communication link to the total data volume.

In this embodiment, by determining, according to communication parameters of a plurality of sub communication links, data volume shares of the data to be transmitted, which can be respectively transmitted by the plurality of sub communication links, the data volume allocated to the sub communication links can be matched with the data transmission capability thereof. When the communication parameters of the communication network provided by the communication service provider corresponding to a certain sub-communication link are determined to have low capability of transmitting data, a small data volume share can be allocated to the sub-communication link; conversely, a larger share of the data amount may be allocated. Thus, more data may be transmitted over a communication network provided by a better communication service provider and poorer data may be transmitted over a communication network provided by a poorer communication service provider.

Referring to fig. 2B, a usage scenario provided by the present embodiment is shown, as shown in the figure, the network access device may be disposed in a vehicle, and the vehicle may be networked through the network access device during a driving process of the vehicle.

For example, the network access device may include three mobile communication modules, which respectively access communication networks provided by three communication service providers of mobile, connectivity, and telecommunications, and establish three sub-communication links, which are hereinafter referred to as a mobile link, a connectivity link, and a telecommunications link, respectively, for convenience of description.

The network access device of the vehicle (illustrated in the figure as a CPE) establishes an aggregated link with the aggregation server nearby, and the aggregated link may include a mobile link, a unicom link, and a telecommunication link.

When the vehicle drives to the cell A, according to the obtained communication parameters of the three sub-communication links, the capability of the mobile link for transmitting data is stronger than the capability of the communication link and the telecommunication link for transmitting data, so that more data volume shares are allocated to the mobile link, and less data volume shares are allocated to the communication link and the telecommunication link. And performing data transmission allocation for the data to be transmitted according to the determined data volume share, so as to transmit the data to the aggregation server through a plurality of sub communication links in the aggregation link according to the respective corresponding data volume shares.

When the vehicle runs to the B cell, if the mobile base station has a coverage hole in the cell, according to the obtained communication parameters, the capability of the mobile link for transmitting data is weaker than the capability of the communication link and the telecommunication link for transmitting data, a smaller data volume share is allocated to the mobile link, a larger data volume share is allocated to the communication link and the telecommunication link, and data is sent according to the adjusted data volume share, so that the data can be sent to the aggregation server through the communication link and the telecommunication link.

According to the scheme provided by the embodiment of the application, the aggregation server with the distance between the network access equipment and the network access equipment within the preset distance range establishes the aggregation link, and the aggregation link comprises the sub communication links established based on the communication networks of different communication service providers, so that data can be rapidly transmitted to the aggregation server through the aggregation link; when data is transmitted, the data to be transmitted can be distributed according to the communication parameters of the sub-communication links of the aggregation link, to transmit the allocated portions of data to the aggregation server via a plurality of sub-communication links of the aggregation link respectively, thereby flexibly distributing data for a plurality of sub communication links according to the communication parameters of the sub communication links, since the plurality of sub communication links included in the aggregated link are established based on communication networks of different communication service providers, therefore, the bandwidth of the aggregation link is larger, and when data is transmitted, the data can be transmitted to the aggregation server based on communication networks provided by different communication service providers, even if the communication network provided by one communication service provider is abnormal, the transmission rate of data can be ensured through the communication networks provided by other communication service providers, so that the scheme provided by the embodiment can ensure high availability and stability of the network.

Fig. 3 is a flowchart illustrating a data transmission method according to an embodiment of the present application, where the method may be applied to the network access device, and as shown in the figure, the method includes:

s301, according to the geographical position information of the network access equipment, obtaining server identifications of a plurality of candidate aggregation servers, of which the physical distance with the network access equipment is within a preset distance range.

In this embodiment, the network access device may send a request to the scheduling center when requesting to establish a communication link with the server, where the request carries geographic location information of the network access device, and the scheduling center may determine, according to the geographic location information of the network access device, a server node within a preset distance range from the network access device, and return a server identifier of the determined server node to the network access device.

The server identifier may include a network address, a domain name, and the like of the server node, which is not limited in this embodiment; in addition, the server identifier returned to the network access device may include one or more identifiers, which is not limited in this embodiment.

S302, respectively testing the network performance of the candidate aggregation servers, determining a target aggregation server from the candidate aggregation servers according to the network performance test results corresponding to the candidate aggregation servers, and establishing an aggregation link with the target aggregation server.

In this embodiment, if the number of the server identifiers determined by the network access device is multiple, the network performance between the network access device and the server nodes corresponding to the multiple server identifiers may be tested, and the server node with the better network communication quality may be selected according to the network performance test result and may form an aggregated link through the multiple mobile communication module sub-communication links. For a specific method for testing network performance, reference may be made to related technologies, which are not described herein again.

In this embodiment, when the aggregation link is specifically established, the communication networks of different communication service providers may be accessed through the plurality of mobile communication modules, and the sub-communication links may be established with the aggregation server through the communication networks according to the server identifier, so as to establish the aggregation link.

In this embodiment, the network access device may establish a sub-communication link with the aggregation server through the plurality of mobile communication modules according to the obtained server identifier, so as to obtain an aggregation link between the network access device and the aggregation server through a combination of the plurality of sub-communication links. As described above, the plurality of sub-communication links included in the aggregated link in this step are established after the mobile communication module accesses communication networks of different communication service providers.

After the aggregated link is established between the network access device and the server node, the aggregated link may be maintained until the network access device applies for disconnecting the sub-communication link. All data of the network access equipment can be sent to the server node through the aggregation link, and then forwarded to the corresponding server by the server node. For example, if the live broadcast is performed through the network access device, the live broadcast data may be sent to the server node through the aggregated link of the network access device, and then forwarded to the server providing the live broadcast service through the server node.

S303, obtaining the communication parameters of the sub communication links in the aggregation link.

In this embodiment, the communication parameter may include at least one of: signal-to-noise ratio, signal strength, bandwidth of a sub-communication link, delay, packet loss rate. The communication parameters of the sub-communication link can be obtained by obtaining parameter information of the mobile communication module, performing network parameter test on the sub-communication link and the like. For a specific scheme for acquiring the communication parameters, reference may be made to related technologies, which are not described herein in detail in this embodiment.

S304, determining the communication quality of the plurality of sub-communication links and the total communication quality corresponding to the plurality of sub-communication links included in the aggregation link according to the communication parameters of the plurality of sub-communication links.

In this embodiment, the communication quality of the sub communication link may be calculated according to the communication parameter of each of the plurality of sub communication links. For example, the plurality of communication parameters may be weighted and summed according to a preset weight, and the obtained summation result is used as the communication quality of the sub communication link. After determining the communication qualities of the plurality of sub-communication links, a ratio of the communication qualities of the plurality of sub-communication links may be calculated.

S305, determining the data volume share of the data to be sent, which can be sent by the plurality of sub communication links respectively, according to the ratio of the communication quality of the plurality of sub communication links to the total communication quality respectively.

For example, if the communication quality of one sub communication link accounts for 30% of the total communication quality, the data amount share of the data to be transmitted sent is 30% of the total data amount.

S306, configuring flow table entries of flow tables corresponding to a plurality of communication links according to the total data amount of the data to be sent and data amount shares which can be respectively sent by the plurality of sub-communication links, so as to indicate the corresponding sub-communication links to send the allocated data to be sent to the aggregation server according to the data amount shares through the flow table entries.

In this embodiment, the sub communication links may correspond to the flow tables one to one, and after the data transmission request is received, the flow table entries of the flow tables corresponding to the sub communication links may be configured according to the total data amount of the data to be sent and the data amount shares that the plurality of sub communication links may send, respectively.

For example, if the terminal requests to transmit data at a speed of 5M/s, the flow entries of the three sub-communication links may be configured in a ratio of 1:2:2 of the data amount, so as to transmit data at speeds of 1M/s, 2M/s, and 2M/s through the three sub-communication links, respectively. Of course, this is only an exemplary illustration, and there may be some error in actual use, which is also within the protection scope of the present application.

Optionally, in this embodiment, the method further includes: encapsulating the data indicated by the corresponding flow table entry according to a UDP protocol through a plurality of mobile communication modules; and sending the packaged data to be sent to the aggregation server through the sub-communication links corresponding to the plurality of mobile communication modules.

Compared with the scheme adopting the TCP protocol, the scheme provided by the embodiment can be more suitable for the transmission of video data by adopting the UDP protocol to encapsulate and transmit data. For a specific scheme for data encapsulation and transmission, reference may be made to related technologies, and this embodiment is not described herein again.

Of course, in other implementations of the present application, other protocols may be used for data encapsulation, which is also within the scope of the present application.

Optionally, in this embodiment, the method further includes: acquiring communication parameters of the aggregated link, and determining whether the aggregated link is abnormal or not according to the communication parameters of the aggregated link; and if the aggregation link is determined to be abnormal, sending data to be sent through the non-aggregated sub communication link based on the routing configuration of the network access equipment. Therefore, when the aggregation link is abnormal, the data to be sent can be ensured to be uploaded normally through the sub-communication link. After determining that the aggregation link is recovered to be normal, the aggregation link can be adopted again to send data to the aggregation server so as to ensure high reliability and stability of the data transmission process.

In this embodiment, whether the aggregation link is abnormal may be determined according to whether the mobile communication module of the aggregation link is trailed, whether the signal quality of the mobile communication module is poor, whether the actual bandwidth of the aggregation link is small, the delay of the aggregation link, or the packet loss rate of the aggregation link; or, it may also be determined whether the aggregated link is abnormal according to whether the server node to which the aggregated link is connected is available. For a specific method for determining the abnormality, reference may be made to related technologies, which are not described herein again.

In this embodiment, when it is determined that the aggregated link is abnormal, data may be sent through the unaggregated sub-communication link according to the default routing configuration of the network access device. For example, if the network access device is provided with a routing priority, a link with a higher priority in the plurality of unaggregated sub-communication links may be used for data transmission according to the routing priority; or, if a load balancing routing policy is set in the network device, the network device may control the plurality of unaggregated sub-communication links to respectively transmit part of the data according to the load balancing routing policy, and finally perform data aggregation at the data transmission destination.

Optionally, in this embodiment, if it is determined that the aggregated link is abnormal, displaying abnormal information of the aggregated link; and acquiring detection operation based on the abnormal information to locate the reason of the abnormal occurrence of the aggregation link. Therefore, maintenance personnel can quickly detect the aggregation link based on the abnormal information, timely position the reason for the abnormity of the aggregation link and solve the problem.

Optionally, in this embodiment, the network access device includes a smart antenna, and the plurality of mobile communication modules are configured to access the communication network through the smart antenna, and the method further includes: determining signal transceiving parameters of a plurality of mobile communication modules accessed to a communication network through the intelligent antenna; and controlling the intelligent antenna to carry out spatial filtering according to the signal receiving and sending parameters so as to adjust the communication transmission intensity corresponding to each mobile communication module when the mobile communication modules are accessed into a communication network through the intelligent antenna. By this time, the direction of the intelligent antenna can be tracked and adjusted according to the signal transceiving parameters respectively corresponding to each mobile communication module, so as to control the space filtering of the intelligent antenna, and further enhance the communication transmission strength when the mobile communication module of the network access equipment accesses the communication network, for example, the communication transmission strength between the mobile communication module of the network access equipment and the communication base station can be enhanced, thereby realizing better data transmission.

The following provides an exemplary description of the scheme provided in the embodiments of the present application through a specific usage scenario.

As shown in fig. 4, the terminal is communicatively connected to a network access device, the network access device is communicatively connected to an aggregation server through an aggregation link, and the aggregation server is communicatively connected to a server of the application.

When an application of the terminal requests to send data, the terminal transmits a request for sending data to be sent to an application program to the network access device, and the network access device can determine data volume shares of the data to be sent, which can be respectively sent by a plurality of sub-communication links, according to respective communication parameters of the plurality of sub-communication links, and fragment the data to be sent according to the determined shares. For example, in the figure, data to be transmitted is divided into 3 pieces, namely data pieces 1, 2 and 3.

And after data fragmentation is carried out, respectively sending the distributed data to be sent to an aggregation server through a plurality of sub communication links in the aggregation link according to the data volume shares corresponding to the sub communication links. For example, to ensure that data can be transmitted to the aggregation server, each data slice may be repeatedly sent to the aggregation server over a different sub-communication link. Illustratively, data segment 1 is repeatedly transmitted to the aggregation server through a mobile link and a telecommunication link, data segment 2 is repeatedly transmitted to the aggregation server through the mobile link and a communication link, and data segment 3 is repeatedly transmitted to the aggregation server through the communication link and the telecommunication link.

After receiving the data fragments, the aggregation server may aggregate the data and transmit the aggregated data to the server of the application program.

When the communication parameters of a certain sub-communication link, such as a mobile link, characterize that the capacity of the certain sub-communication link for transmitting data is weak, a larger data volume share can be allocated to other sub-communication links, so as to ensure high availability of the aggregation link.

In this embodiment, before the live broadcast terminal sends data through the network access device, it may be determined whether to use the aggregation link for video data transmission, and if it is determined to use the aggregation link, the network access device sends an aggregation link request for applying for a bandwidth resource for video transmission to a scheduling center of the server, so as to establish an aggregation link with the aggregation server through the above steps. The specific implementation method of the above steps can refer to the above embodiments, and is not described herein again.

Illustratively, the link may be as follows: and a communication link: the telecommunication link is in a proportion of 0:3:5, the video data are sent to the aggregation server through the three sub-communication links, and the aggregation server can aggregate multiple video data to obtain original video data and forward the original video data to the live broadcast cloud.
