Description

A UDP-based data transmission confirmation method and base station

technical field

The invention relates to the field of data transmission, in particular to a UDP-based data transmission confirmation method and a base station.

Background technique

In network communication, because User Datagram Protocol (UDP, User Datagram Protocol) has the characteristics of low resource consumption and fast processing speed when processing data packets, it is widely used in audio, video and data transmission. The main function of UDP is to compress network data traffic into the form of data packets, but UDP does not provide data packet grouping, assembly, and cannot sort data packets, and the receiving end does not send confirmation to received packets. Therefore, some data services choose UDP as the transport layer protocol based on the characteristics of low transmission overhead. However, in order for the server to determine whether the data transmission is successful or not and decide whether to continue the transmission or stop the transmission, an additional message confirmation mechanism needs to be added at the application layer. Ensure the reliability of data transmission. For example, TFTP (Trival File Transfer Protocol, simple file transfer protocol) is a simple file transfer protocol based on the UDP protocol. The user terminal uses an ACK (Acknowledgment, confirmation character) packet as a message confirmation packet to inform the server that it has successfully received data.

Using a message confirmation packet mechanism such as an ACK packet, although reliable transmission based on the UDP protocol can be realized, it also brings about the problem of increased transmission network resource overhead similar to the TCP (Transmission Control Protocol, Transmission Control Protocol) protocol. In particular, the ACK packet message based on the UDP protocol has a single function and is only used to confirm the reception of the packet. The packet format is simple and the packet length is extremely small. When the network is sent from the user terminal to the base station, and then forwarded by the base station to the server, it is necessary to superimpose UDP encapsulation and IP (Internet Protocol, a protocol for interconnection between networks) encapsulation. The size of the data part of the IP packet is even smaller than the size of the header. Secondly, in the mobile network The ACK packet needs to be further encapsulated into a physical layer data packet. The actual information carried by the ACK packet is small, and the encapsulation and packet header occupy more resources than the data to be transmitted, which causes the transmission resources of the wireless network to be wasted. Therefore, how to improve the transmission efficiency of ACK packets, thereby improving the utilization rate of uplink transmission resources has become an urgent problem to be solved.

Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

It should also be noted that, in the embodiments of the present invention, "的 (English: of)", "corresponding (English: corresponding, relevant)" and "corresponding (English: corresponding)" can sometimes be used in combination. It should be pointed out that , when the difference is not emphasized, the meanings they want to express are consistent.

In the prior art, in the UDP-based data transmission process between the server, the base station, and the user terminal, the message confirmation packet used to confirm the successful transmission of the data packet has a simple format and a very small packet length, so that it is between the user terminal and the server. The size of various encapsulated data that needs to be added in wireless network transmission is even larger than the actual data size that needs to be transmitted in the message confirmation packet, which is a waste of uplink wireless resources to a certain extent, so a new UDP-based data is needed The transmission confirmation scheme is used to reduce this waste, so as to achieve the effect of improving the utilization rate of uplink wireless resources.

In view of the above problems, referring to Fig. 1, an embodiment of the present invention provides a UDP-based data transmission confirmation method, the method comprising:

101. The base station receives the data packet sent by the server and parses the data packet to obtain IP quintuple information of the data packet.

Specifically, the parsing of the data packet mentioned here is to separate the encapsulation of the data packet from the original data, and decapsulate the various information contained in the encapsulation of the data packet, wherein the IP quintuple information obtained by parsing includes: destination IP Address, source IP address, destination port number, source port number, and transport layer protocol fields.

102. The base station judges whether the transport layer protocol of the data packet is UDP according to the transport layer protocol field in the IP quintuple information, and judges the application layer protocol type of the data packet according to the destination IP address and destination port number in the IP quintuple information .

Specifically, when the value of the transport layer protocol field is different, the transport layer protocol is also different. In the prior art, each transport layer protocol corresponds to a value; the base station in step 102 according to the transport layer protocol in the IP quintuple information Whether the field determines whether the transport layer protocol of the data packet is the User Datagram Protocol UDP may specifically include: the base station obtains the value of the transport layer protocol field according to the transport layer protocol field in the IP quintuple information; if the value of the transport layer protocol is a preset value , then the transport layer protocol of the data packet is UDP; in the prior art, the value of the transport layer protocol field for UDP is 17.

103. When the base station determines that the transport layer protocol of the data packet is UDP and the application layer protocol of the data packet is the type that needs to transmit a message confirmation packet, the base station sends the data packet to the corresponding user terminal according to the destination IP address, and sets a timer at the same time start the timer.

Specifically, the application layer protocol that needs to transmit the message confirmation packet mentioned here is generally a UDP-based application layer protocol designed to ensure the reliability of data packet transmission, such as TFTP; when the data packet uses this type of application layer protocol, After the user terminal establishes a communication channel with the server and prepares to send the data packet, it will determine which application layer protocol the data packet uses. If it is such a UDP-based application layer protocol, it will return to indicate that the user terminal has received it. A message acknowledgment packet for the received data packet is sent to the server, or an error packet for indicating that the data packet cannot be received is returned to the server when the data packet cannot be received; for example, the destination port number corresponding to TFTP is usually 69.

It should be noted that when the IP quintuple information of the data packet cannot determine that the transport layer protocol of the data packet is UDP and the application layer protocol of the data packet is the type that needs to transmit a message confirmation packet, according to its transport layer protocol and application layer The protocol performs data transmission and confirmation. The specific situation depends on the actual situation and will not be described here.

104. When the time counted by the timer is equal to the threshold value of the timer, the base station simulates the user terminal according to the IP quintuple information and the application layer protocol to generate a message confirmation packet and send it to the server.

Specifically, the threshold value of the timer mentioned here is the sum of the round-trip time length of the data packet between the base station and the user terminal and the time length for the user client to process and generate an error packet. Usually, the base station and the user terminal The length of the round-trip time for data transmission between terminals is certain, and the length of time for the user terminal to find that it cannot receive the data packet and then process and generate an error packet is related to the processing capability of the user terminal, so the threshold value of the timer The setting is mainly related to the processing capability of the user terminal. The stronger the processing capability of the user terminal, the shorter the corresponding timer threshold value. Of course, the shortest time is greater than the data transmission between the base station and the user terminal. If everything is normal, the user terminal will have received the data packet before the timer reaches the threshold, and the base station will generate the IP address based on the analysis of the data packet when the timer reaches the threshold. The tuple information generates a message confirmation packet and sends it to the server, because the message confirmation packet is generated based on the analysis information of the data packet, that is, the message confirmation packet is equivalent to that generated by the base station simulating the user terminal, so the server receives the message confirmation After confirming that the user has received the data packet, the user can prepare to send the next data packet.

The UDP-based data transmission confirmation method provided by the above-mentioned embodiments, in this method, when the transport layer protocol of the data packet is UDP and the application layer protocol needs to return a message confirmation packet, the base station sends the data packet received from the server For the user terminal, set a timer. The threshold value of the timer is the sum of the round-trip time length of the data packet between the base station and the user terminal and the time length of the user client to process and generate an error packet. If all Normally, the user terminal will have received the data packet before the timer reaches the threshold value, and the base station will generate a message confirmation according to the IP quintuple information generated by analyzing the data packet when the timer reaches the threshold value Because the message confirmation packet is generated based on the analysis information of the data packet, that is, the message confirmation packet is equivalent to being generated by the base station simulating the user terminal, so the server determines that the user has received the message confirmation packet after receiving the message confirmation packet The data packet can prepare the sending of the next data packet; therefore, in the whole process of the method, the user terminal does not need to send a message confirmation packet to the base station through the wireless network, which saves the use of network resources at this stage, thereby improving the uplink wireless resources. utilization rate.

As shown in FIG. 2, another embodiment of the present invention also provides a UDP-based data transmission confirmation method as a further supplementary description of the UDP-based data transmission confirmation method provided in the above-mentioned embodiment. The method includes:

201. The base station receives the data packet sent by the server and parses the data packet to obtain IP quintuple information of the data packet.

202. The base station judges whether the transport layer protocol of the data packet is UDP according to the transport layer protocol field in the IP quintuple information, and judges the application layer protocol type of the data packet according to the destination IP address and destination port number in the IP quintuple information .

203. When the base station determines that the transport layer protocol of the data packet is UDP and the application layer protocol of the data packet is the type that needs to transmit a message confirmation packet, the base station sends the data packet to the corresponding user terminal according to the destination IP address, and sets a timer at the same time start the timer.

2041. When the time counted by the timer is equal to the threshold value of the timer, the base station simulates the user terminal according to the IP quintuple information and the application layer protocol to generate a message confirmation packet and send it to the server.

2042. If the time counted by the timer is less than the timer threshold and the base station receives the error packet sent by the user terminal, the base station controls the timer to stop timing and sends the error packet to the server; the error packet is used to indicate that the user terminal failed to receive the packet.

Exemplarily, when the base station sends a data packet to the user terminal, the user terminal also has a timer. Normally, the user terminal will successfully receive the data packet when the timer reaches the threshold value, but if data congestion occurs Or other reasons cause the user terminal to fail to receive the data packet when the timer time reaches the timer threshold, the user terminal will generate an error packet and send it to the base station to inform the base station that the user terminal has failed to receive the data normally Of course, the user terminal can also detect the transmission of the data packet in real time after establishing a communication channel with the base station. If the channel is congested and cannot receive the data packet, it will generate an error packet and send it to the base station. How does the user terminal generate an error packet? Depending on the actual situation, this is only an example situation, and the specific situation is not limited.

205. The base station controls the reset of the timer, and controls the timer to start timing when the next transmission layer protocol is UDP and the application layer protocol is a type of data packet that needs to transmit a message confirmation packet.

Specifically, in order to ensure the continuity of the data packets sent by the base station, after the timing work of the sending process of the timer is completed, the timer restarts the timing work when the base station needs to send a data packet of the same nature next time.

The UDP-based data transmission confirmation method provided by the embodiment of the present invention, because the method includes: the base station receives the data packet sent by the server and parses the data packet to obtain the Internet Protocol IP quintuple information of the data packet; the base station according to the IP quintuple information The transport layer protocol field in the data packet judges whether the transport layer protocol of the data packet is the user datagram protocol UDP, and judges the application layer protocol type of the data packet according to the destination IP address and destination port number in the IP quintuple information; when the base station determines that the data When the transport layer protocol of the packet is UDP and the application layer protocol of the data packet is the type that needs to transmit a message confirmation packet, the base station sends the data packet to the corresponding user terminal according to the destination IP address, and sets the timer to start counting; when the timer When the timing time is equal to the timer threshold value, the base station simulates the user terminal according to the IP quintuple information and the application layer protocol to generate a message confirmation packet and send it to the server. In this method, when the transport layer protocol of the data packet is UDP and the application layer protocol needs to return a message confirmation packet, the base station sets a timer when sending the data packet received from the server to the user terminal, and the timer The threshold value is the sum of the round-trip time length of the data packet between the base station and the user terminal and the length of time the user client processes and generates an error packet. If everything is normal, the user terminal will count to the threshold value in the timer The data packet has been received before, and the base station generates a message confirmation packet according to the IP quintuple information generated by analyzing the data packet when the timer reaches the threshold value, and sends it to the server, because the message confirmation packet is based on The message acknowledgment packet generated from the analysis information of the data packet is equivalent to that generated by the base station simulating the user terminal, so the server can prepare to send the next data packet after receiving the message acknowledgment packet after confirming that the user has received the data packet; In the whole process of the method, the user terminal does not need to send a message confirmation packet to the base station through the wireless network, which saves the use of network resources at this stage, thereby improving the utilization rate of uplink wireless resources.

The packet is sent to the user terminal, and the timer is set to start counting at the same time; When the timer timing time is equal to the timer threshold value, the simulation module is used to simulate the user terminal to generate a message confirmation packet according to the IP quintuple information of the data packet obtained by the analysis module and send it by the module is sent to the server. 7. The base station according to claim 6, wherein the parsing module is specifically used for: Obtain the value of the transport layer protocol field according to the transport layer protocol field in the IP quintuple information; If the value of the transport layer protocol field is a preset value, the transport layer protocol of the data packet is UDP. 8. The base station according to claim 6, wherein if the timer counting time is less than the timer threshold value, the receiving module receives the error packet sent by the user terminal, and the sending module further It is used to control the timer to stop timing and send the error packet to the server; the error packet is used to indicate that the user terminal failed to receive the data packet successfully. 9. The base station according to claim 6, characterized in that, when the timer counting time is equal to the timer threshold value, the sending module controls the timer reset, and sends the transport layer protocol next time When the UDP and the application layer protocol are data packets that need to transmit message confirmation packets, the timer is controlled to start counting. 10. The base station according to claim 8, characterized in that, the sending module resets the timer after controlling the timer to stop counting, and sends the next time the transport layer protocol is UDP and the application layer protocol is required The timer is controlled to start counting when a data packet of the message confirmation packet type is transmitted.
