Technical field

The present application relates to the field of communications, and in particular, to a method, a node device, and a server for adjusting a transmission rate.

Background technique

In a wireless network, because the air interface environment is complex and variable, the actual rate that the terminal can obtain generally varies greatly depending on factors such as the location and time of the terminal. In practical applications, the commonly used transmission control protocol (TCP) algorithm generally cannot adapt well to the rapidly changing wireless environment. The following problems exist: the transmission window management of common TCP algorithms is relatively conservative, and the continuous loss of packets/bandwidth in sporadic In the scenario where the sudden link quality deteriorates suddenly, the penalty is too serious, and after the link quality is restored, the transmission window cannot be recovered quickly. The sending window in the startup process of the commonly used TCP algorithm is a slow detection type, and it takes a long time to reach a state suitable for the current transmission link, and a reasonable transmission rate of the link bandwidth cannot be quickly and accurately identified.

In the prior art, the slow detection mode is: when the transmitting end sends the downlink data for the first time, the transmission rate is set to a relatively small transmission value, such as 1 Mbit/S, when it is confirmed that the terminal can correctly receive the transmitting end. After the transmitted data packet, the transmitting end will adjust the transmission rate to the next time, for example, to 2Mbit/S. After confirming that the terminal can correctly receive the data packet sent by the transmitting end, the transmitting end will raise the transmission rate next time. For example, adjust to 3Mbit/S. And so on, until the success rate of the terminal receiving the data packet is lower than a certain value, it is determined that the terminal can obtain the highest rate.

Therefore, with the prior art solution, when the transmitting end rates the terminal to the terminal, the transmitting end cannot quickly restore the highest transmission rate that the terminal can obtain to the terminal, thereby affecting the efficiency of data transmission.

Detailed ways

The embodiment of the present application provides a method for adjusting a transmission rate, a node device, and a server, which are used to reasonably adjust a transmission rate of a server to send data to a terminal, and improve efficiency of data transmission.

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The terms "first", "second", "third", "fourth", etc. (if present) in the specification and claims of the present application and the above figures are used to distinguish similar objects without having to use To describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a system applied to a method for adjusting a transmission rate according to an embodiment of the present application. FIG. 1 includes a terminal used by a user, a server that performs data interaction with the terminal, and a node device in a network transmission process. The terminal may be a device with a network interaction capability, such as a mobile phone, a tablet computer, a personal computer (PC), or a wearable device, which is not limited herein. The server is a sender that sends downlink data to the terminal, and the server may be a server of an operator of an application installed in the terminal, and is not limited herein. The node device is a device of a network node that needs to be experienced in the process of data transmission between the terminal and the server. The node device may be a device with network data forwarding or processing capability, such as a base station, a switch, a router, a firewall device, and a proxy device. Make a limit.

In the present application, in the process of data interaction with the server, due to factors such as the location change or time change of the terminal, the link quality of the consecutive consecutive packet loss/bandwidth burst may be deteriorated. In order for the server to correctly receive the data packet sent by the server, the server will punish the downlink transmission rate of the terminal. For example, when a user views a video online through a terminal, the normal downlink transmission rate is 5 Mbit/s. When the user hands-held the terminal to the elevator, the downlink rate is 5 Mbit/s when the server is blocked. When data is sent, serious packet loss will occur, and the terminal cannot receive a large number of packets sent by the server. Therefore, the server will perform the penalty of the downlink rate and lower the downlink transmission rate to 1 Mbit/S. This reduces the packet loss. When the signal of the terminal returns to normal, the server needs to know the transmission rate that the terminal can obtain at this time in time, and then adjust the downlink transmission rate to a reasonable rate to improve the transmission efficiency with the terminal.

In this application, the current transmission rate of the terminal can be obtained by the node device, thereby calculating the current available transmission rate of the terminal, and the node device sends the transmission rate available to the terminal to the server, so that the server can obtain the information according to the terminal. The transmission rate adjusts the rate at which downlink data is sent to the terminal next time. In this way, when the signal quality of the terminal is good, the server can accurately know the transmission rate that the terminal can obtain, thereby adjusting the downlink rate to the transmission rate achievable by the terminal, and improving the transmission efficiency.

Referring to FIG. 2, FIG. 2 is a schematic diagram of an embodiment of a method for adjusting a transmission rate according to an embodiment of the present application, including the following steps:

201. The node device acquires a current transmission rate of the terminal, where the terminal is a terminal that performs data interaction with the server.

The current transmission rate of the terminal may be the transmission rate of the terminal measured by the node device. For example, the node device is a base station, and the base station detects the size of the data packet sent to the terminal within a period of time, and calculates the current transmission rate of the terminal according to the size of the data packet and the length of the detected time period. For example, the base station sends a data packet of 20 Mbit size to the terminal within 10 seconds, so that the base station can calculate that the current transmission rate of the terminal is 20 Mbit/10S=2 Mbit/s.

202. The node device generates rate adjustment reference information according to the current transmission rate of the terminal.

After the node device obtains the current transmission rate of the terminal, the rate adjustment reference information may be generated according to the transmission rate.

In a possible implementation, the node device may generate a transmission rate obtainable by the terminal according to the current transmission rate of the terminal plus the remaining rate, where the remaining rate is a rate calculated by the node device according to the remaining air interface resources and the transmission quality of the terminal. . For example, the node device is a base station, and the base station detects that the current transmission rate of the terminal is 2 Mbit/s, and the base station detects the transmission quality of the terminal, and evaluates the spectrum efficiency of the terminal by using the transmission quality, for example, the spectrum estimated by the base station according to the transmission quality. The efficiency is 0.7 bit/S/Hz; the base station also needs to detect the current remaining air interface resources of the cell, for example, the remaining air interface resource is 10 MHz, then the base station can calculate the remaining rate by multiplying the estimated spectrum efficiency and the remaining air interface resources: 10*0.7=7Mbit/S. The base station adds the calculated current transmission rate to the calculated remaining rate, and can obtain the transmission rate that the terminal can truly obtain: 2+7=9 Mbit/s.

In another possible implementation manner, the node device may not calculate the transmission rate obtainable by the terminal according to the current transmission rate of the terminal, but the node device generates the rate adjustment reference information by combining the parameter content obtained by the computing terminal to the transmission rate. For example, the rate adjustment reference information includes a current transmission rate of the terminal, remaining air interface resources, and transmission quality of the terminal. After the node device sends the rate adjustment reference information to the server, the server calculates the transmission rate that the terminal can obtain.

203. The node device sends rate adjustment reference information to the server.

After the node device generates the rate adjustment reference information, the rate adjustment reference information needs to be sent to the server, and the server adjusts the downlink rate of the terminal.

In a possible implementation manner, the node device may separately send the rate adjustment reference information to the server in the form of a message.

In another possible implementation manner, the node device may also insert the rate adjustment reference information into the uplink packet sent by the terminal to the server, for example, in an option field of the TCP ACK, the node device will insert the rate again. The uplink packet of the reference information is sent to the server.

In another possible implementation manner, if the network structure is a network structure in which a mobile edge computing (MEC) device is deployed, the node device may insert the rate adjustment reference information into a user plane of the GPRS tunneling protocol (GPRS). Tunnelling protocol-user plane) A GTP-U packet, for example, in the private field of the header in the packet. When detecting the packet, the MEC device inserts the rate adjustment reference information in the private field of the packet into the Option of the TCP ACK and sends the packet to the server. Optionally, if the server deploys a proxy mechanism in the MEC device, the MEC device can implement the function of sending the downlink data by the server, and the MEC device parses the rate adjustment reference information in the GTP-U packet. The MEC device can adjust the reference information to adjust the rate at which the MEC device sends downlink data to the terminal next time.

204. The server receives the rate adjustment reference information from the node device.

In a possible implementation manner, the rate adjustment reference information is information about a rate that is obtained by the terminal that is calculated by the node device. In another possible implementation, the rate adjustment reference information includes the current transmission rate of the terminal. Information about the remaining air interface resources and the transmission quality of the terminal.

205. The server adjusts, according to the rate adjustment reference information, a transmission rate of data to be sent to the terminal next time.

After receiving the rate adjustment reference information, the server needs to adjust the reference information according to the rate to adjust the transmission rate of the data sent to the terminal next time.

In a possible implementation manner, the rate adjustment reference information is information about a rate that the terminal device calculates, and the server adjusts the transmission rate of the data sent to the terminal to the transmission rate obtainable by the terminal. For example, if the transmission rate available to the terminal is 9 Mbit/s, then the server adjusts the transmission rate of the next time to send data to the terminal to be 9 Mbit/s, and sends the terminal to the terminal at the transmission rate of 9 Mbit/s without abnormality. Downstream data.

In another possible implementation, the rate adjustment reference information is information including the current transmission rate of the terminal, the remaining air interface resources, and the transmission quality of the terminal, and then the server needs to calculate the transmission rate available to the terminal. For example, the server calculates a transmission rate obtainable by the terminal according to the current transmission rate of the terminal plus the remaining rate, where the remaining rate is a rate calculated by the server according to the remaining air interface resources and the transmission quality of the terminal. The server then adjusts the transmission rate of the next data transmission to the terminal to the transmission rate available to the terminal.

It should be noted that the execution process of the embodiment of FIG. 2 may be performed periodically, or may be triggered when the terminal sends uplink data, which is not limited herein.
