Method and system for establishing data connection

Abstract

The invention discloses a method and system for establishing data connection. The method comprises the following steps: a server receives the connection data of a first device and a second device, sends the connection data of the first device to the second device and sends the connection data of the second device to the first device; the first device and the second device separately judge whetherthe other is in the same local area network according to the received connection data; when the judgment results of the first device and the second device are both true, the server separately configures the first device and the second device as a server end and a client end which are in IP connection and separately sends configuration information to the first device and the second device; and theserver end monitors connection, and the client end initiates connection and establishes data connection between the first device and the second device. The system comprises the server, the first device and the second device. The scheme provided by the invention can be used to realize the automatic and high-speed connection between two devices.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for establishing a data connection. Background technique [0002] In the prior art, a high-speed connection can be established between two devices through necessary manual setting steps and a data line with a relatively high transmission rate. However, this manual setting step is more complicated and not easy to operate. [0003] The WiFi technology is an industry term issued by an organization named the Wireless Ethernet Compatibility Alliance (Wireless Ethernet Compatibility Alliance, hereinafter referred to as: WECA). It is a short-range wireless transmission technology capable of supporting radio signals for Internet access over a wide range. For example, the most common one is a wireless router. In the effective range covered by the radio wave of this wireless router, a wireless network connection can be used for networking. [0004] With the con...

Problems solved by technology

However, when a device wants to establish a connection with another device through its WiFi function and perform data transmission and other actions, it needs to go through complicated configuration work

figure 1 It is a schematic diagram of communication between two WiFi wireless devices in the prior art, such as figure 1 As shown, when two WiFi wireless devices establish a connection through an access point (Access Point, hereinafter referred to as: AP) transit mode, the two devices need to record each other's IP address or network device name, etc. to communicate with each other. Communication, and the IP address or device name may change frequently, making it necessary to continuously update the other party's IP address or device name, which is very poor in feasibility
