Problems solved by technology

Under the current network environment, when a wireless terminal is switched from one access point to another, the IP address of the terminal device will change, which will lead to disconnection and reconnection of the network. What the terminal user sees is the network Stuck or disconnected, resulting in network instability and affecting the use of users

Embodiment 1

[0033] In the field of wireless communication, mobile terminal users often experience dropped calls and unstable connections due to changes in IP addresses. Especially for automobile communications, since automobiles are usually in a state of high-speed movement for a long time, how to maintain The stability of the wireless communication between the car and the server, and between cars has become a problem that must be solved. see figure 1, in this embodiment, a wireless terminal data transmission method based on QUIC technology is provided, which is applied to the wireless communication of automobiles, which is conducive to maintaining the stability of communication and reducing the phenomenon of dropped calls and stuttering. QUIC is a new communication protocol based on multiplexing and secure transmission. Specifically, the wireless terminal data transmission method based on QUIC technology includes the following steps,

Embodiment 2

[0051] refer to Figure 3-5 In this example, a car data transmission system based on QUIC technology is proposed in this embodiment. The above-mentioned car data transmission method based on QUIC technology can be realized by relying on this system, and the data that is stable and not easy to drop is formed between moving cars. transmission. Specifically, the vehicle data transmission system based on QUIC technology includes a wireless terminal device 100 , a server 200 and a connection module 300 . Among them, the wireless terminal device 100 is a vehicle-mounted terminal installed on a car, a smart phone, etc. as a terminal device. The wireless terminal device 100 moves at a high speed with the car, and can initiate a connection request and provide local services to customers; the server 200 can respond to wireless terminal The request of the device 100 is processed, and the composition of the server usually includes a processor, hard disk, memory, system bus, etc., which i...

Abstract

The invention discloses an automobile data transmission method and system based on QUIC technology, and the method comprises the following steps that wireless terminal equipment initiates QUIC connection to a server, and the QUIC connection comprises primary connection and secondary connection; the server side monitors the connection request of the wireless terminal equipment, establishes connection with the wireless terminal equipment and can send data to the wireless terminal equipment; a session id is generated for connected wireless terminal equipment, and when a terminal user switches anaccess point, the terminal user can access a network again within keep-alive timeout of the session id. The automobile data transmission method and system based on the QUIC technology have the beneficial effects that the automobile data transmission method and system based on the QUIC technology can have access to the network and transmit data when automobiles move at a high speed. Meanwhile, connection and transmission stability is ensured, offline and jamming are reduced, and the automobile data transmission method and system can also be used for connection and data transmission among multiple automobiles.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a wireless terminal data transmission method based on QUIC technology. Background technique [0002] After the current society enters the era of mobile Internet, there are more and more demands for stable and high-speed network access and real-time interconnection of mobile terminals in mobile scenarios. When the user uses the wireless terminal device 100 to access the network, it will be assigned a temporary IP address. When the user disconnects and reconnects or switches the access point, the IP address may change. The user uses this IP address to establish a TCP or UDP connection with the server in the public network, and then obtains network video voice or other services. Among them, the TCP / UDP connection is a five-tuple session, and the five-tuple includes source IP address, source port, If any one of the destination IP address, destination port and...
