TCP keep-alive method, device and system

Abstract

The embodiment of the invention provides a TCP keep-alive method, a TCP keep-alive device and a TCP keep-alive system. The method is applied to a first device, the first device comprises a coprocessor and an application processor, and the method comprises the steps that the application processor determines that a first service is a white list service and sends a first request to the coprocessor, and the first request is used for requesting to keep a first TCP connection corresponding to the first service alive; the coprocessor receives a first request from the application processor, and obtains a first TCP connection keep-alive message according to the identifier of the first service and the identifier of the first TCP connection; and the coprocessor broadcasts and sends the first TCP connection keep-alive message in a Bluetooth mode. According to the scheme, the TCP connection keep-alive can be carried out on the white list, the TCP connection of the service does not need to be destroyed and rebuilt frequently, and the equipment overhead can be reduced. And moreover, the TCP connection keep-alive message is broadcasted and sent in a Bluetooth mode, so that the power consumption is relatively low, and low-power-consumption TCP connection keep-alive is realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular, to a TCP keep-alive method, device, and system. Background technique [0002] With the popularization of smart devices, various smart devices have entered thousands of households, and the data interaction between business cross-device is becoming more and more common, and the number of Transmission Control Protocol (Transmission Control Protocol, TCP) connections between devices has greatly increased. [0003] When the terminal device goes to sleep with the screen off or the physical layer of the Wireless Local Area Network (WLAN) is disconnected, the TCP connections established by various services on the terminal device will be destroyed. When the subsequent screen is turned on and the WLAN physical layer connection is restored , it needs to consume a lot of time and resources to establish TCP connections and service connections of various se...

[0003] When the terminal device goes to sleep with the screen off or the physical layer of the Wireless Local Area Network (WLAN) is disconnected, the TCP connections established by various services on the terminal device will be destroyed. When the subsequent screen is turned on and the WLAN physical layer connection is restored , it needs to consume a lot of time and resources to establish TCP connections and service connections for various services, resulting in high overhead for terminal equipment
