Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the embodiments of the present invention.

[0021] The following further illustrates the specific implementation of the embodiments of the present invention with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Embodiment 1

[0023] The first embodiment of this application provides a data transmission method, which is applied to a network device. For the convenience of understanding, the application scenario of the data transmission method provided in the first embodiment of this application is described. Refer to Figure 1 as shown Figure 1 The schematic diagram of the scenario of a data transmission method provided in the first embodiment of this application. Figure 1 The scenario shown includes a network device 101 and a terminal device 102; the network device 101 may be the device that executes the data transmission method provided in the first embodiment of this application.

[0024] The terminal device 102 can be a smart phone, a tablet computer, a laptop computer, a smart speaker, etc. The terminal device 102 can also access the network through the network device 101 and perform data interaction through the network. In this application, the network includes a local area network (English: Local Area Network, LAN), a wide area network (English: Wide Area Network, WAN), and a mobile communication network; such as the World Wide Web (English: World Wide Web, WWW), Long Term Evolution (English: Long Term Evolution, LTE) network, 2G network (English: 2th Generation Mobile Network), 3G network (English: 3th Generation Mobile Network), 5G network (English: 5th Generation Mobile Network), etc. Of course, this is only an exemplary illustration here and does not represent that this application is limited to this. The network device 103 can include various devices connected through the network, for example, servers, relay devices, device-to-device (English: Device-to-Device, D2D) devices, base stations, etc.

[0025] As Figure 1 shown, the network device 101 can receive the data sent by the terminal device, add status information to the data in the first protocol layer, and then send the data after adding the status information through the network. Combining Figure 1 shown scenarios, the data transmission method provided in Embodiment 1 of this application will be described in detail. It should be noted that Figure 1 is only an application scenario of the data transmission method provided in Embodiment 1 of this application and does not represent that the data transmission method must be applied to Figure 1 shown scenarios. Referring to Figure 2 shown, Figure 2 is a flowchart of a data transmission method provided in Embodiment 1 of this application. The method includes the following steps:

[0026] Step 201, obtain the first transmission data.

[0027] The first transmission data includes the data in the application layer of the network protocol. The network protocol can be a seven-layer protocol, a four-layer protocol, etc. For example, the seven-layer protocol includes the application layer, the presentation layer, the session layer, the transport layer, the network layer, the data link layer, and the physical layer; another example is that the four-layer protocol includes the application layer, the network layer, the data link layer, and the physical layer. Of course, this is only an exemplary illustration here and does not represent that this application is limited to this.

[0028] Step 202, obtain the status information related to the network.

[0029] The network can be the network to which the network device that executes the data transmission method belongs, that is, the current network, or it can be other networks. This application does not limit this. The status information can indicate network bandwidth, the location of the terminal device, the cell to which the terminal device belongs, the congestion status of the network, etc. The terminal device can be the device that sends the first transmission data, that is, the source of the first transmission data. Here, five specific examples are listed and described respectively:

[0030] Optionally, in the first example, obtaining status information related to the network includes: obtaining the network bandwidth and generating status information, where the status information includes information about the network bandwidth. The network device can detect the network bandwidth and generate status information based on the detected network bandwidth, or it can be that the network device receives the network bandwidth detected by the detection device and generates status information. This application does not limit the source of the status information. It can be detected by the network device itself or the result received from other detection devices.

[0031] Optionally, in the second example, obtaining status information related to the network includes: obtaining location information and generating status information. The location information is used to indicate the location of the terminal device corresponding to the first transmission data, and the status information includes the location information. The terminal device corresponding to the first transmission data can be the terminal device that sends the first transmission data. The location of the terminal device can be determined by the network device according to the data transmission path, or it can be determined according to the location of the router or base station connected to the terminal device. This application does not limit this.

[0032] Optionally, in the third example, obtaining status information related to the network includes:

[0033] obtaining cell information and generating status information. The cell information is used to indicate the network status of the cell to which the terminal device corresponding to the first transmission data belongs, and the status information includes the cell information. In the third example, the terminal device is communicatively connected to the base station, and the corresponding cell information can be obtained according to the information of the base station.

[0034] Optionally, in the fourth example, obtaining status information related to the network includes: generating status information according to the congestion status of the network. The congestion status of the network can be detected by the network device or sent to the network device by other devices after detection.

[0035] Optionally, in the fifth example, obtaining status information related to the network includes: generating status information according to the transmission delay of the network. The transmission delay of the network can be determined by the network device according to the delay of receiving data, or it can be sent to the network device by other devices after detection.

[0036] The above five examples only illustrate the content that the status information can include, and do not represent that this application is limited thereto. The status information can be used to indicate the status of the network or the status of the devices in the network.

[0037] It should be noted that step 201 and step 202 may not have a sequential order and can be executed simultaneously or not simultaneously. This application does not limit this. After step 201 and step 202, the method further includes:

[0038] Step 203: For the first transmission data, add status information to the data in the first protocol layer to obtain the second transmission data.

[0039] The first transmission data includes the data in the first protocol layer in the network protocol, and the first protocol layer is different from the application layer. The first protocol layer can be a non-application layer, that is, other protocol layers except the application layer; or, it can also be said that the first protocol layer is the lower layer of the application layer, because the application layer is usually the top layer in the network protocol, and the data of the first protocol layer is the lower layer data of the application layer. It should be noted that the network protocol can be a seven-layer protocol, a four-layer protocol, etc. For example, the seven-layer protocol includes the application layer, presentation layer, session layer, transport layer, network layer, data link layer, and physical layer; another example is that the four-layer protocol includes the application layer, network layer, data link layer, and physical layer. Of course, this is only an exemplary illustration here and does not represent that this application is limited thereto. In the seven-layer protocol and the four-layer protocol, the application layer is the top layer, and the first protocol layer can be the presentation layer, session layer, transport layer, network layer, data link layer, or the first protocol layer can also be the network layer, data link layer, physical layer, and these all belong to the lower layer of the application layer. The data of the first protocol layer can include transport layer data, network layer data, data link layer data, physical layer data, etc. Adding status information to the data of the first protocol layer will not change the protocol of the application layer, avoid affecting the data of the application layer, and because it does not involve the protocol of the application layer, it has better adaptability and scalability.

[0040] An extension header can be added to the transport layer data or the data of the second protocol layer. The second protocol layer can be other layers in the network protocol except the application layer and the transport layer. Add the status information to the extension header to obtain the second transmission data. For example, optionally, for the first transmission data, adding status information to the data in the first protocol layer to obtain the second transmission data includes: for the first transmission data, adding an extension header to the transport layer data, and the data of the first protocol layer includes the transport layer data; adding the status information to the extension header of the transport layer to obtain the second transmission data.

[0041] An extension header is added to the data in the transport layer without changing the original fields in the transport layer and without causing major changes to the transport layer protocol, further enhancing adaptability and scalability. It should be noted that the unused free fields in the data of the transport layer can be set as the extension header, or the free data bits in the data of the transport layer can be set as the extension header. Alternatively, if there is already an extension header in the data of the transport layer, only the data bits of the extension header need to be increased and status information can be added to the newly added data bits. Of course, this is only an exemplary illustration here and does not mean that the present application is limited to this.

[0042] Optionally, in one implementation, for the first transmission data, adding status information to the data in the first protocol layer to obtain the second transmission data includes:

[0043] For the first transmission data, adding an extension header to the data in the GTP-U (General Packet Radio Service Tunneling Protocol-User) layer, where the data in the first protocol layer includes the data in the GTP-U layer; adding the status information to the extension header in the GTP-U layer to obtain the second transmission data. Since the GTP-U layer can contain a large amount of information, adding an extension header and status information in the GTP-U layer can carry more information content and does not change the application layer data, not only increasing adaptability and scalability but also ensuring the information capacity.

[0044] Optionally, in another implementation, for the first transmission data, adding status information to the data in the first protocol layer to obtain the second transmission data includes: for the first transmission data, adding an extension header to the data in the second protocol layer, where the data in the first protocol layer includes the data in the transport layer and the data in the second protocol layer, and the second protocol layer is different from the transport layer; adding the status information to the extension header in the data of the second protocol layer to obtain the second transmission data. Adding an extension header and status information in the data of the second protocol layer enables the receiving party to obtain the status information without parsing to the higher layer but only parsing to the second protocol layer after receiving the second transmission data, reducing the parsing complexity.

[0045] It should be noted that adding status information to the data in the first protocol layer can be achieved by re-encapsulating the data. For example, obtaining the first transmission data includes: receiving the first transmission data under the protocol of the first interface through the first interface.

[0046] For the first transmission data, status information is added to the data at the first protocol layer to obtain second transmission data, including: de-encapsulating the first transmission data according to the protocol of the first interface, and encapsulating the de-encapsulated first transmission data according to the protocol of the second interface to obtain second transmission data, where the status information is encapsulated in the data at the first protocol layer.

[0047] The interface protocols of the network device can be different when receiving and sending data. The first transmission data is parsed according to the first interface protocol, and then when encapsulating using the second interface protocol, the status information is encapsulated in the data at the first protocol layer, without changing the original data transmission process, thus improving the data transmission efficiency; if the first interface protocol and the second interface protocol are the same, and the network device only forwards the data, then it only needs to parse the data to the first protocol layer, that is, the layer where the status information is encapsulated, and send it after encapsulating the status information in the first protocol layer. It should be noted that the first interface protocol may not include the first protocol layer, and the first protocol layer can be a protocol layer under the second interface protocol. The first transmission data under the second interface protocol can include data at the application layer and data at the first protocol layer.

[0048] Here, taking the network device as a base station as an example, the first transmission data is received through the first interface, including: receiving the first transmission data under the protocol of the air interface through the air interface, where the first interface includes the air interface.

[0049] For the first transmission data, status information is added to the data at the first protocol layer to obtain second transmission data, including: de-encapsulating the first transmission data according to the protocol of the air interface, and encapsulating the de-encapsulated first transmission data according to the protocol of the Internet Protocol (IP) interface to obtain second transmission data, where the status information is encapsulated in the data at the first protocol layer.

[0050] Generally, data is transmitted between the terminal device and the base station using the air interface, that is, the first interface protocol is the air interface protocol, and data is transmitted between the base station and other network devices (such as relay devices, servers, etc.) using the IP (Internet Protocol) interface, that is, the second interface protocol is the IP protocol. Of course, here it is only illustrated with the base station as an example, and it does not mean that this application is limited thereto.

[0051] Step 204: Transmit the second transmission data.

[0052] The data transmission method provided by the embodiment of the present invention obtains first transmission data, where the first transmission data includes data in the application layer of the network protocol; obtains status information related to the network; for the first transmission data, adds the status information to the data in the first protocol layer to obtain second transmission data, where the first transmission data includes data in the first protocol layer of the network protocol, and the first protocol layer is different from the application layer; and sends the second transmission data. Since the status information is added to the data in the first protocol layer, there is no need to parse and modify the application layer data. Instead, the status information is obtained from the data in the first protocol layer for data transmission optimization, which can adapt to more protocols and has better adaptability and scalability.

[0053] Embodiment 2

[0054] Combined with the data transmission method described in Embodiment 1 above, Embodiment 2 of the present application provides a data transmission method, which details the execution steps of the data receiver in Embodiment 1, that is, the method of the receiver of the second transmission data in step 204. Refer to Figure 3 as shown in Figure 3 FIG. 10 is a flowchart of a data transmission method provided by Embodiment 2 of the present application. The method includes the following steps:

[0055] Step 301, receive the second transmission data.

[0056] The second transmission data includes data in the application layer and data in the first protocol layer of the network protocol, and the first protocol layer is different from the application layer. The description of the second transmission data can refer to the description in Embodiment 1 and will not be elaborated here.

[0057] Step 302, parse the second transmission data and obtain the status information from the data in the first protocol layer.

[0058] The status information is used to indicate the status of the network. The status information can indicate network bandwidth, the location of the terminal device, the cell to which the terminal device belongs, the congestion status of the network, etc. The terminal device can be the device that sends the first transmission data, that is, the source of the first transmission data. The description of the status information can refer to the description in Embodiment 1 and will not be elaborated here.

[0059] Step 303, adjust the network parameters according to the status information and transmit data according to the adjusted network parameters.

[0060] Adjusting network parameters is a process of optimizing data transmission. Network parameters can include network bandwidth, which can also be said to be the sending window and the receiving window. For example, when the status information indicates that the network status is poor (e.g., the network bandwidth is small or there is network congestion), the network bandwidth can be increased according to the status information. When the status information indicates that the network status is good (e.g., the network bandwidth is large or there is no network congestion), the network bandwidth can be decreased according to the status information. Network parameters can also include routing information. For example, when the status information indicates that the network status is poor, other transmission links with better network status can be selected for data transmission. Of course, this is only an exemplary illustration here and does not mean that this application is limited thereto. The status information can indicate the current network status. Adjust network parameters according to the status information and transmit data according to the adjusted network parameters, including: adjusting the network parameters of the current network according to the status information and transmitting data according to the adjusted network parameters. Because the receiving end can timely obtain the network status of the current network and adjust the network parameters according to the network status of the current network, so that data transmission can adapt to the current network in real time and improve the utilization rate of network resources.

[0061] The data transmission method provided by the embodiment of the present invention receives second transmission data, and the second transmission data includes data in the application layer and data in the first protocol layer in the network protocol; parses the second transmission data, and obtains status information in the data in the first protocol layer, where the status information is used to indicate the network status; adjusts network parameters according to the status information, and transmits data according to the adjusted network parameters. Because status information is added to the data in the first protocol layer, there is no need to parse and modify the application layer data, but to obtain status information from the data in the first protocol layer for data transmission optimization, which can adapt to more protocols and has better adaptability and scalability.

[0062] Embodiment Three

[0063] Based on the data transmission methods described in the above Embodiment One and Embodiment Two, Embodiment Three of this application provides a data transmission method, taking the network device as a base station as an example for detailed description. Of course, this is only an exemplary illustration here and does not mean that this application is limited thereto. To facilitate understanding of the data transmission method described in this Embodiment Three, the scenario used in this Embodiment Three is described. As Figure 4 shown, Figure 4 is a scenario schematic diagram of a data transmission method provided by Embodiment Three of this application, Figure 4 showing a base station 401, a terminal device 402, and other network devices 403.

[0064] The terminal device sends the first transmission data to the base station. The base station obtains the status information, parses and repackages the first transmission data to obtain the second transmission data, and encapsulates the status information in the data of the first protocol layer during the encapsulation process. The base station transmits the second transmission data to other network devices.

[0065] Combined with Figure 4 the scenario shown in Figure 5 as shown in Figure 5 FIG. is an interaction diagram of a data transmission method provided in Embodiment 3 of the present application. The method includes the following steps:

[0066] Step 501, the terminal device sends the first transmission data to the base station.

[0067] Combined with Figure 4 the scenario shown in

[0068] Step 502, the base station obtains the status information of the network.

[0069] Taking the status information including the network bandwidth of the current network as an example, the base station can detect the network bandwidth of the current network and generate the status information.

[0070] Step 503, the base station adds the status information to the data in the first protocol layer of the first transmission data to obtain the second transmission data.

[0071] The base station can receive the first transmission data through the air interface, parse the first transmission data according to the air interface protocol, and then encapsulate it according to the IP interface protocol to obtain the second transmission data. The status information is encapsulated in the transport layer. The second transmission data can include the application layer, the transport layer, the network layer, the data link layer, and the physical layer.

[0072] Among them, the transport layer may include the GTP-U layer, the status information may be encapsulated in the extension header of the GTP-U layer, the network layer may include the UDP (User Datagram Protocol) layer or the IP layer; the data link layer may include the L2 layer, and the physical layer may include the L1 layer. Of course, this is only an exemplary description here and does not mean that the present application is limited thereto.

[0073] Exemplarily, the data of the GTP-U layer may include information type, information length, source address, destination address, tunnel endpoint identifier, and extension header. Of course, this is only an example to illustrate the fields included in the GTP-U layer, and it does not mean that this application is limited thereto.

[0074] Step 504: The base station sends the second transmission data to other network devices.

[0075] Other devices may include relay devices. For example, UPF (User Plane Function) devices, or may also include servers, etc. This application does not limit this.

[0076] Step 505: Other network devices perform data transmission optimization according to the status information included in the second transmission data.

[0077] It should be noted that other network devices may also continue to send the second transmission data in the same method as the base station. For example, other network devices may obtain the status information, add the status information to the data of the second transmission data in the first protocol layer to obtain the third transmission data, and send the third transmission data.

[0078] Combined with Figure 4 In the shown application scenario, taking the relay device as an example, the intermediate device may send the third transmission data to the server, or may also send it to the base station. This application does not limit this. That is, the data transmission method described in the embodiments of this application may be that the base station transmits data to the relay device, or the terminal device transmits data to the base station; it may be that the relay devices transmit data to each other; it may also be that the relay device transmits data to the server, or the server transmits data to the relay device.

[0079] The data transmission method provided by the embodiments of the present invention includes obtaining first transmission data, where the first transmission data includes data of the application layer in the network protocol; obtaining status information related to the network; for the first transmission data, adding the status information to the data of the first protocol layer to obtain second transmission data, where the first transmission data includes data of the first protocol layer in the network protocol, and the first protocol layer is different from the application layer; and sending the second transmission data. Because the status information is added to the data of the first protocol layer, there is no need to parse and modify the application layer data, but to obtain the status information from the data of the first protocol layer for data transmission optimization, which can adapt to more protocols and has better adaptability and scalability.
