Method, device and system for maintaining long connection and medium

Abstract

The invention discloses a method, device and system for maintaining long connection and medium. Specifically, the method comprises the following steps: a client generates a random number in a set period, sends a heartbeat data packet carrying the random number to a server and adds the random number into a random number array, if a heartbeat response data packet which is returned by the server andcarries the random number is received, deleting the random number in the random number array. Therefore, the client can select the corresponding setting strategy according to the number of the randomnumbers in the random number array; the period is set according to the selected setting strategy, the heartbeat data packet is sent according to the set period instead of a fixed period, so that thesending number of heartbeat data packets is reduced as much as possible, the loads of the client and the server are reduced, and the power consumption of the terminal equipment where the client is located is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device, system and medium for maintaining a persistent connection. Background technique [0002] In order to ensure the continuity of communication and the timeliness of data push, it is usually necessary to establish and maintain a long connection between the client and server of the application software. At present, a common way to maintain a long connection between the client and the server is that the client periodically sends a heartbeat packet to the server to ensure that there is always data transmission between the client and the server to prevent the connection from being automatically cut off by the operator. . This method of maintaining a long connection not only increases the network traffic, but also increases the load on the client and the server, and the frequent sending of heartbeat data packets will also lead to excessive power consum...

Problems solved by technology

[0004] Embodiments of the present invention provide a method, device, system, and medium for maintaining a persistent connection, which are used to solve the problems of high network traffic consumption, heavy client and server loads, and problems in the prior art for maintaining a persistent connection. The problem of high power consumption of the terminal device where the client is located, and solve the problem that when the client runs in the background for a long time, the long connection is automatically cut off by the operating system of the terminal device where the client is located, resulting in unavailable connection and due to the inability of the client The problem that the client cannot automatically rebuild the long connection due to the perceived connection being cut off
