Network channel maintaining method based on UDP protocol

Abstract

The invention discloses a network channel maintaining method based on a UDP (User Datagram Protocol). The network channel maintaining method comprises the following steps: step 1, establishing connection between terminal device and a server and finishing registration through the server; step 2, the terminal device maintains communication with the server through a network channel, which comprises the following steps: the terminal device sends a plurality of one-way heartbeat data packets to the server; the terminal device sends a bidirectional heartbeat data packet to the server, and the sharedtime of sending the unidirectional heartbeat data packet and the bidirectional heartbeat data packet is heartbeat interval time; the server sends a response data packet to the terminal device after receiving the bidirectional heartbeat data packet of the terminal device; and the terminal device receives the response data packet of the server, adjusts or maintains the heartbeat interval time, andincreases the heartbeat interval time if the response data packet is not received continuously for many times. The heartbeat interval time is prolonged as much as possible to save the flow on the premise of ensuring normal maintenance of the network channel, and the method is suitable for different network supplier core network environments.

Description

technical field [0001] The invention relates to a method for maintaining a mobile communication network channel, in particular to a method for maintaining a network channel based on the UDP protocol. Background technique [0002] Mobile communication terminal physical network equipment (such as some remote controllers, remote detection equipment), can connect to the server through the 2G, 3G, 4G network provided by the network operator through the TCP protocol or UDP protocol, and generate data interaction with the server. The TCP (Transmission Control Protocol) protocol here is the Transmission Control Protocol, which is a connection-oriented, reliable, byte-stream-based transport layer communication protocol, defined by RFC 793 of the IETF; the UDP (User Datagram Protocol) protocol is the user data The packet protocol is a protocol that provides applications with the ability to send encapsulated IP packets without establishing a connection. [0003] The server has a fixed...

Problems solved by technology

[0009] This solution uses timing to exchange data with the server, for example, sending a two-way heartbeat packet to the server at a timing of 30 seconds, and the server gives a response at the same time to maintain the network channel, the server can know the network channel corresponding to the terminal device ID, and can send data to the terminal device at any time Sending a message, but this solution will greatly increase the traffic consumption because the two-way heartbeat data packet is invalid data; for example, sending a two-way heartbeat data packet to the server at regular intervals of 30 seconds, the monthly traffic consumption is about 15M, which consumes a lot of traffic
