Broadband radio access system and method

Abstract

The invention provides a system and a method for broadband wireless access; wherein, the broadband wireless access system consists of a control subsystem, an access subsystem and a WIFI wireless access subsystem. The control subsystem is connected to the access subsystem and directly connected to the user terminal and / or connected to the WIFI wireless access subsystem through the Ethernet port toconnect the user terminal in order to receive the input parameters from the user terminal directly or through the WIFI wireless access subsystem and invokes the background processing programs to convert the input parameters into AT commands which are transmitted to the subsystem. The access subsystem, which is connected wirelessly to the user external network, is used for receiving the AT commands from the control subsystem, resolving the AT commands and invoking the corresponding internal function in order to connect or disconnect the user terminal with the external networks. The WIFI wireless access subsystem, which is wirelessly connected to the user terminal, is used for receiving the input parameters from the user terminal and transmitting the input parameters to the control subsystem.

Description

technical field [0001] The present invention relates to a communication system, in particular to a broadband wireless access system and a broadband wireless access method. Background technique [0002] In the field of information communication, the two technologies with the fastest development speed and the greatest impact on people are broadband network technology and wireless mobile communication technology. The combination of these two technologies is broadband wireless access technology. Broadband wireless access technology refers to a broadband access technology in which wireless links are used for communication links between user terminals and service switching points. [0003] Broadband wireless access technologies can be divided into three types in terms of coverage: local broadband wireless access, metropolitan broadband wireless access, and wide area network broadband wireless access technologies. In terms of supporting terminal mobility, broadband wireless access...

Problems solved by technology

However, the current wireless data card is only suitable for high-end notebook Internet access, which cannot meet the wireless Internet access needs of ordinary PC users, and is affected by the price, so that the wireless mobile office has not been fully released and popularized.

[0008] For enterprise users, the current access terminals that meet wireless Internet access are mainly wireless routers, which can satisfy multiple PC or notebook terminals to access the Internet, but its internal implementation is actually a PC plus wireless network card technology solution, which brings a high price. High, unable to popularize the wireless Internet access requirements of individual or family users

[0009] For users who use PCs, the existing 3G mobile wireless access terminals are mainly based on the serial port of the PC connected to a wireless MODEM (modem) to realize the wireless Internet access function, but due to the speed limit of the serial port, the broadband multimedia of the 3G network cannot be used characteristic

At the same time, special PC-side software is required, which increases the user's use burden and technical requirements

[0010] The 3G mobile wireless access terminal using the USB port can achieve high-speed communication, but due to the limitation of the connection distance with the PC, the signal reception of the wireless access terminal cannot be optimized, which may affect the communication quality and rate.

[0011] The wireless public phones, wireless network cards, and wireless routers currently on the market either have single functions, separate voice and data services, or are too expensive to be popularized.

Especially for remote areas where wired access cannot be reached, users will have to purchase two types of access terminals to implement voice and data services, which not only increases the cost, but also increases the technical burden of users
