Wireless access system and method thereof

Abstract

The present invention provides a broadband wireless access system, which includes a control subsystem and an access subsystem. The control subsystem includes a processing module and an interface module, wherein, the processing module is used to perform data processing, the interface module connected with the processing module is used for connecting with a user terminal; after the processing module receives the input parameters from the user terminal via the interface module, a background processing program is invoked, the input parameters are converted into an AT instruction. The access subsystem connected with the control subsystem via an interface is used to parse the AT instruction sent by the control subsystem via the interface and invoke the related internal function, so that the user terminal can be connected with or disconnected with a network. Consequently, by the present invention, based on a dual inline microprocessor and by supporting Ethernet high-speed interfaces connected with PCs (personal computers), a requirement on the high-speed network access of a WCDMA / HSDPA (Wideband Code Division Multiple Access / High Speed Downlink Packet Access) network can be satisfied, and meanwhile, a basic talking service is also supported.

Description

technical field [0001] The present invention relates to the technical field of third-generation mobile communication wireless access, and more specifically, relates to a dual-embedded microprocessor-based Ethernet high-speed interface that supports connection with a PC and can meet the high-speed Internet access requirements of WCDMA / HSDPA networks. A wireless access system and method supporting basic call services. 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 d...

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 the wireless MODEM to realize the wireless Internet access function, but due to the speed limit of the serial port, the broadband multimedia characteristics of the 3G network cannot be used

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 a single function and separate voice and data services, or are expensive and cannot 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 increases the cost and technical burden of users
