The first transmission data includes data of an application layer in a network protocol. The network protocol may be a seven layer protocol, a four layer protocol, etc. For example, a seven-layer protocol includes an application layer, a presentation layer, a session layer, a transport layer, a network layer, a data link layer, a physical layer; as another example, a four-layer protocol includes an application layer, a network layer, a data link layer, and a physical layer. Of course, this is merely an example and does not represent a limitation of the present application.
The network may be a network to which the network device executing the data transmission method belongs, that is, a current network, or other networks, and the present application is not limited thereto, and the state information may indicate a network bandwidth, a location of the terminal device, a cell to which the terminal device belongs, a congestion status of the network, and the like. The terminal device may be the device that sends the first transmission data, i.e. the source of the first transmission data. Here, five specific examples are listed for explanation:
optionally, in a first example, obtaining status information related to a network includes: acquiring the network bandwidth and generating state information, wherein the state information comprises the information of the network bandwidth. The network device can detect the bandwidth of the network and generate the state information according to the detected network bandwidth, or the network device receives the bandwidth of the network detected by the detection device and generates the state information.

It should be noted that, step 201 and step 202 may not have a sequential order, and may be executed simultaneously or executed non-simultaneously, which is not limited in this application, and after step 201 and step 202, the method further includes:
The first transmission data includes data of a first protocol layer in the network protocol, the first protocol layer being different from the application layer. The first protocol layer may be a non-application layer, i.e., a protocol layer other than the application layer; alternatively, the first protocol layer may be a lower layer of the application layer, because the application layer is usually the uppermost 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 may be a seven-layer protocol, a four-layer protocol, etc. For example, a seven-layer protocol includes an application layer, a presentation layer, a session layer, a transport layer, a network layer, a data link layer, a physical layer; as another example, a four-layer protocol includes an application layer, a network layer, a data link layer, and a physical layer.

The data of the first protocol layer can comprise transport layer data, network layer data, data of a data link layer, physical layer data and the like, the protocol of the application layer cannot be changed by adding state information in the data of the first protocol layer, the influence on the data of the application layer is avoided, and the adaptability and the expansibility are better because the protocol of the application layer is not involved.
An extension header may be added to transport layer data or data of a second protocol layer, where the second protocol layer may be a layer other than an application layer and a transport layer in a network protocol, and the status information is added to the extension header to obtain second transmission data, for example, optionally, for first transmission data, adding the status information to data of a first protocol layer to obtain second transmission data, including: for first transmission data, adding an extension header in the data of a transmission layer, wherein the data of a first protocol layer comprises the data of the transmission layer; and adding the state information into an extension header of the transmission layer to obtain second transmission data.
The extension head is added in the data of the transmission layer, the original field in the transmission layer is not changed, the protocol of the transmission layer is not greatly changed, and the adaptability and the expansibility are further enhanced. It should be noted that, an unoccupied free field in the data of the transport layer may be set as an extension header, or a free data bit in the data of the transport layer may be set as an extension header, or the data of the transport layer has an extension header, and only the data bit of the extension header needs to be added, and state information is added to the newly added data bit.
Optionally, in an implementation manner, for first transmission data, adding state information to data in the first protocol layer to obtain second transmission data, including:
for the first transmission data, adding an extension header in data of a GTP-U (General Packet Radio Service Tunneling Protocol-User, User plane General Packet Radio Service tunnel Protocol) layer, wherein the data of the first Protocol layer comprises data of the GTP-U layer; and adding the state information into an expansion head of a GTP-U layer to obtain second transmission data. Because the GTP-U layer can contain a large amount of information, the expansion head is added in the GTP-U layer, and the state information is added, so that more information contents can be transmitted, and the application layer data is not changed, thereby not only increasing the adaptability and the expansibility, but also ensuring the information capacity.
Optionally, in another implementation manner, for the first transmission data, adding state information to data in the first protocol layer to obtain second transmission data, including: for the first transmission data, adding an extension head in the data of a second protocol layer, wherein the data of the first protocol layer comprises the data of a transmission layer and the data of the second protocol layer, and the second protocol layer is different from the transmission layer; and adding the state information into an extension header of the data of the second protocol layer to obtain second transmission data. And adding an extension head in the data of the second protocol layer and adding state information, so that after receiving the second transmission data, a receiver does not need to analyze to a high layer, only needs to analyze to the second protocol layer, and can obtain the state information, thereby reducing the complexity of analysis.
It should be noted that, adding the state information to the data in the first protocol layer may be to repackage the data, for example, acquiring the first transmission data, including: first transmission data under a protocol of the first interface is received through the first interface.
For the first transmission data, adding state information in the data of the first protocol layer to obtain second transmission data, including: and decapsulating the first transmission data according to a protocol of the first interface, encapsulating the decapsulated first transmission data according to a protocol of the second interface to obtain second transmission data, and encapsulating the state information in data of the first protocol layer.
The interface protocol of the network equipment can be different when receiving data and sending data, the first transmission data is analyzed according to the first interface protocol, and then the state information is encapsulated in the data of the first protocol layer when the second interface protocol is used for encapsulation, the original flow of data transmission is not changed, and the efficiency of data transmission is improved; if the first interface protocol is the same as the second interface protocol, and the network device only forwards the data, the network device only needs to analyze the data to the first protocol layer, that is, the layer for encapsulating the state information, and encapsulate the state information in the first protocol layer and then send the encapsulated state information. It should be noted that the first interface protocol may not include the first protocol layer, the first protocol layer may be a protocol layer under the second interface protocol, and the first transmission data under the second interface protocol may include data of the application layer and data of the first protocol layer.
Here, taking the example that the network device is a base station, receiving the first transmission data through the first interface includes: first transmission data under a protocol of an air interface is received over the air interface, the first interface including the air interface.
For the first transmission data, adding state information in the data of the first protocol layer to obtain second transmission data, including: and decapsulating the first transmission data according to a protocol of an air interface, encapsulating the decapsulated first transmission data according to a protocol of an Internet Protocol (IP) interface to obtain second transmission data, and encapsulating the state information in data of a first protocol layer.
Generally, data transmission is performed between a terminal device and a base station by using an air interface, that is, a first interface Protocol is an air interface Protocol, data transmission is performed between the base station and other network devices (for example, a relay device, a server, etc.) by using an IP (Internet Protocol) interface, that is, a second interface Protocol is an IP Protocol, which is, of course, only a base station is taken as an example here for description, and the present application is not limited thereto.
And step 204, sending second transmission data.
The data transmission method provided by the embodiment of the invention comprises the steps of obtaining first transmission data, wherein the first transmission data comprises data of an application layer in a network protocol; acquiring state information related to a network; for first transmission data, adding state information in data of a first protocol layer to obtain second transmission data, wherein the first transmission data comprises data of the first protocol layer in a network protocol, and the first protocol layer is different from an application layer; and sending the second transmission data. Because the state information is added in the data of the first protocol layer, the data of the application layer does not need to be analyzed and modified, but the state information is obtained from the data of the first protocol layer for data transmission optimization, so that the method can adapt to more protocols, and has better adaptability and expansibility.

The second transmission data comprises data of an application layer in a network protocol and data of a first protocol layer, and the first protocol layer is different from the application layer. The description of the second transmission data may refer to the description in the first embodiment, and is not repeated here.
The status information is used to indicate the status of the network. The status information may indicate network bandwidth, location of the terminal device, cell to which the terminal device belongs, congestion status of the network, etc. The terminal device may be the device that sends the first transmission data, i.e. the source of the first transmission data. For the description of the status information, reference may be made to the description in the first embodiment, and details are not described here.
And 303, adjusting the network parameters according to the state information, and transmitting data according to the adjusted network parameters.
Adjusting network parameters is a process for optimizing data transmission, where the network parameters may include a network bandwidth, or may also be a sending window and a receiving window, for example, when the state information indicates that the network state is not good (e.g., the network bandwidth is small or the network is congested), the network bandwidth may be increased according to the state information, and when the state information indicates that the network state is good (e.g., the network bandwidth is large or the network is not congested), the network bandwidth may be decreased according to the state information; the network parameters may also include routing information, for example, when the status information indicates that the network status is not good, other transmission links with good network status may be selected for data transmission. Of course, this is merely an example and does not represent a limitation of the present application. The state information may indicate a state of a current network, adjust a network parameter according to the state information, and transmit data according to the adjusted network parameter, including: and adjusting the network parameters of the current network according to the state information, and transmitting data according to the adjusted network parameters.

Because the state information is added in the data of the first protocol layer, the data of the application layer does not need to be analyzed and modified, but the state information is obtained from the data of the first protocol layer for data transmission optimization, so that the method can adapt to more protocols, and has better adaptability and expansibility.
