Embodiment Construction

[0036] The basic idea of ​​the present invention is: during data transmission, the data information including the identity authentication information is sent to the corresponding terminal user according to the WiFi network confirmed by the identity authentication information.

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The implementation method of the specific embodiment of data transmission in the WiFi network of the present invention is as follows: figure 2 shown, including the following steps:

[0039]Step 201: After confirming that the terminal user is within the range of the public local area network of multiple WiFi networks, send identity authentication information to each WiFi network, and confirm the WiFi network used;

[0040] Here, the identity authentication information includes: the authentication function flag, the content of the authentication function...

Abstract

A method for data transmission in WiFi network is disclosed in the present invention, which comprises: when the data is transmitted, a WiFi network which is determined according to identity identification authentication information sent by a mobile terminal sends data information which contains the identity identification authentication information to the corresponding mobile terminal. A system for data transmission in the WiFi network is also disclosed in the present invention at the same time. With the method and the system of the invention, collision in WiFi network can be efficiently avoided and the problem of avoiding data collision by increasing Inter Frame Space (IFS) in the operation process of Carrier Sense Multiple Access / Collision Avoidance (CSMA / CA) protocol can be solved, and therefore efficiency of interaction between the network side and the user terminal is improved.

Description

technical field [0001] The present invention relates to a wireless fidelity (WiFi, Wireless Fidelity) network technology, in particular to a method and system for data transmission in a WiFi network. Background technique [0002] WiFi network is one of the mainstream standards of wireless local area network at present. It is the same as the Bluetooth network, which belongs to the short-range wireless transmission technology that can be used in offices and homes. Compared with Bluetooth technology, WiFi has the following advantages: [0003] First of all, the coverage of WiFi network is wide. The radio wave coverage based on Bluetooth technology is very small, with a radius of only about 50 feet, or about 15 meters, while the radius of WiFi technology can reach about 300 feet, or about 100 meters. Therefore, the WiFi network is within the scope of the entire building. can be used. Moreover, a new type of switch recently launched can extend the communication distance of th...
