Near field wireless local area network communication method of mobile terminal devices, and system using same

Abstract

The invention provides a near field wireless local area network communication method of mobile terminal devices, wherein the method is suitable for at least two mobile terminal devices, and one of the mobile terminal devices is defined as the mobile terminal device A. The method is characterized by comprising the following steps that: the mobile terminal device A builds an ad hoc network and performs radio broadcasting, and provides wireless access nodes for other mobile terminal devices; the mobile terminal device A and other mobile terminal devices search and safely access to the ad hoc network via the wireless access nodes; and the mobile terminal devices verified in the network build a near field wireless communication link with each other, and exchange data in the communication link according to a communication protocol. Simultaneously, the invention provides a system using the near field wireless local area network communication method based on the scheme, wherein the system comprises a wireless transmission module, a connection control module, a processing module, an access module, an audio input/output module and a security module.

Description

technical field [0001] The present invention relates to a short-distance wireless local area network communication method and system for mobile terminal equipment Background technique [0002] At present, there are many ways to build a short-distance wireless network. One is to use the proprietary network provided by the network operator. Although this method is mobile and flexible in use, it completely depends on the proprietary network provided by the operator. Once the network fails, the signal is unstable or the network is blocked, the data transmission of the wireless network will be seriously affected. The second is through transfer equipment, such as commonly used wireless routers, wireless APs, etc. The wireless network established by this method is relatively stable, but on the one hand, it needs to increase the cost of equipment; on the other hand, the transfer equipment is generally considered not to be mobile. In this way, the user cannot establish a wireless ne...

[0002] At present, there are many ways to build a short-distance wireless network. One is to use the proprietary network provided by the network operator. Although this method is mobile and flexible in use, it completely depends on the proprietary network provided by the operator. Once the network fails, the signal is unstable or the network is blocked, it will seriously affect the data transmission of the wireless network

The second is through transfer equipment, such as commonly used wireless routers, wireless APs, etc. The wireless network established by this method is relatively stable, but on the one hand, it needs to increase the cost of equipment; on the other hand, the transfer equipment is generally considered not to be mobile. In this way, users cannot establish wireless networks anytime and anywhere, and the use is not flexible enough.
