The 3G technology standard comprises: three kinds of TD-SCDMA, WCDMA and CDMA2000.At present, country greatly develops the 3G industry, 3G network first phase website has started 3G (Third Generation) Moblie " Chinese Industrial Standards (CIS) " TD-SCDMA socialization operational trials and merchant on probation in 10 cities, indicate that the commercial applications of China 3G (Third Generation) Moblie standard TD is formally set sail.WCDMA/CDMA2000 also progressively enters commercial stage.
Yet, traditional communication module, or be designed to the master control formula module of mobile phone, or be designed to the module of passive modulation modulator-demodulator, like this for the 3G communication module, the CPU of same base band need design two kinds of circuit and two sets of plan, and need handle two cover networking licences in Information Industry Department, like this, must be double problem with regard to having development cost and design time, and the change of mobile phone scheme the time redesigns mainboard again, will inevitably increase development cost.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of saving development cost, and convenient the use has the active of support and the changeable multi-functional 3G communication module of the principal and subordinate of passive type working method double nip.
The purpose of this utility model is achieved in that the changeable multi-functional 3G communication module of a kind of principal and subordinate, comprise the 3G module that constitutes by base band CPU, RF radio frequency chip, internal memory and FLASH storage and corresponding power supply and interface, it is characterized in that described interface comprises first interface and second interface; Described first interface is the I/O interface that is used for mobile phone peripheral hardware coupling, and described second interface be the MINI PCI-E interface that mates with PC, inserted computer, gateway or base station.
Further, described mobile phone peripheral hardware comprises a kind of in the following equipment at least: display screen, keyboard, loudspeaker, microphone, camera.
Compared to existing technology, the utlity model has following advantage:
This 3G module, at first can be used as the passive modulation modulator-demodulator, being installed in becomes 3G net book or 3G gateway/base station in PC net book or the gateway/base station, the master control dialer software generally need be contained in the 3G terminal, and the protocol software in the module then can respond the routine call in the 3G terminal; During as modulator-demodulator, generally its interface adopts MINI PCI-E standard.This 3G module can be used as active mobile phone main control module again, and its function software then is contained in the 3G module in advance, and starts automatically and independent operating after energized; Main control module and the I/O interface and the PCI-E interface that then adopt special use being connected of external equipments such as other screens, keyboard, loudspeaker.The 3G inside modules can be pre-installed a kind of software of application; Also the software of multiple application can be installed simultaneously, can adopt the mode that software and hardware switches to enter different master slave modes; Can provide the later stage software upgrade method to upgrade in addition.
In the 3G communication module described in the utility model, shared base band CPU, RF radio frequency chip and internal memory and FLASH on same base band CPU adopt the mode of double nip, support the active and passive type working method of 3G communication module.Need two sets of plan to compare with original same base band CPU, saved Products Development expense and design time, and production cost also reduces greatly with two kinds of circuit.
Description of drawings:
Fig. 1 is the frame principle figure of the changeable multi-functional 3G communication module of the utility model principal and subordinate.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As described in Figure 1, the changeable multi-functional 3G communication module of a kind of principal and subordinate comprises the 3G module that is made of base band CPU, RF radio frequency chip, internal memory and FLASH storage and corresponding power supply and interface, and described Peripheral Interface comprises first interface and second interface; Described first interface is the I/O interface that is used for mobile phone peripheral hardware coupling, and described second interface be the MINI PCI-E interface that mates with PC, inserted computer, gateway or base station.
Described base band CPU and chip module also comprise RF radio frequency chip, internal memory DDR and NADN FLASH memory.Described mobile phone peripheral hardware comprises a kind of in the following equipment at least: display screen, keyboard, loudspeaker, microphone, camera.
In the 3G communication module described in the utility model, the 3G communication module of same base band CPU, the mode of employing double nip, the active and passive type working method of support 3G communication module.Promptly can be as active mobile phone core board, and, connect screen, keyboard, loudspeaker, microphone, the first-class external equipment of shooting by special I/O interface, can be used as the passive modulation modulator-demodulator again, adopt the PCI-E interface, called by PC, inserted computer, gateway or base station.In addition, the most complicated during the design of mobile phone and 3G terminal is the radiofrequency signal and the interference problem of HFS, therefore the utility model is developed the 3G general module, other parts of mobile phone just can be designed to interface board, a 3G communication module can be used in the mobile phone or portable terminal of different profiles, thereby become 3G mobile, 3G net book, 3G gateway or 3G Home eNodeB etc.
