Description
Technical field
The present invention relates to the communications field, relate in particular to Bluetooth wireless technology and TD-SCDMA 3G (Third Generation) Moblie standard.
Background technology
Gateway (Gateway) is a kind of computer system or equipment that serves as access or information translation, is the bonded products that connects the software and hardware of heterogeneous networks.Using between different communication protocol, data format or the language even the diverse two kinds of systems of system, gateway is a translater; By packaging information again so that they can be read by another system, with the demand of adaptation to end system.
Bluetooth (Bluetooth) is the short distance radio communication standards of being developed jointly by mobile operator and mobile computing company, is a kind of small-sized, economic, the short-range Radio Link of setting up between portable computer, mobile phone and other mobile device.The frequency range of this regulation and stipulation work is public ISM band, and peak data rate can reach 3Mbps.Utilize the equipment of Bluetooth technology communication to spread all trades and professions at present, as mobile phone, notebook, PDA, digital camera etc.These equipment are by Bluetooth technology wirelessly transmitting data easily.
The 3G (Third Generation) Moblie standard that TD-SCDMA proposes as China (being called for short 3G), from 1998 formally since ITU (International Telecommunication Association) submits to, gone through the time about ten years, expert group assessment, ITU approval and issue, the fusion of standard, a series of International standardization work such as introducing of new technology characteristic have been finished with 3GPP (third generation partnership projects) system, propose by China thereby make the TD-SCDMA standard become first, based on radio communication international standard Intellectual Property Right in China, that accepted extensively in the world and approve.
Bluetooth conduct novel short-distance wireless communication technology has in recent years obtained extensive use in every field.TD-SCDMA is as the 3G (Third Generation) Moblie standard of China's independent intellectual property right, and present national 3G license is provided, and can predict the application of following TD-SCDMA network in two years and certainly will will popularize in China.Till that time, interconnecting between the main flow communication networks such as blueteeth network and TD-SCDMA network will be necessary thing, but bluetooth is two kinds of different consensus standards with TD-SCDMA, carry out between bluetooth and the TD-SCDMA that inter-network is interconnected just need carry out protocol conversion with gateway, and in existing wireless communication protocol conversion equipment, also do not have bluetooth/TD-SCDMA gateway, making at present also can't direct communication between these two kinds of networks.Therefore, how to address this problem and to be main contents of the present invention.
