Description
Technical field
The present invention relates to a kind of communicator, particularly a kind of communicator that the radio communication of second specification that differs from first specification that a main frame provides is provided.
Technical background
The first generation of mobile communication system is to adopt analog signal transmission, owing to can not satisfy user's demand, and oneself market of fading out gradually.The mobile communication system of the second generation then changes adopts digital data transmission, comprise global system for mobile communications (Global System for Mobile Communication, GSM) and code division multiple access access technique (code-division multiple access, CDMA) etc., and based on integration General Packet Radio Service (GPRS) (the General Packet Radio Service of GSM, GPRS), the mobile communication system that then was called as for the 2.5th generation.At the same time, (PersonalHandy-phone System's lower powered personal mobile communication system PHS) also comes into the market with the advantage of low consumption and high frequency range.(Third Generation 3G), then will have great progress to the 3-G (Generation Three mobile communication system) that is developed at present aspect voice and the data transmission technology.
GSM is present modal communication system, mainly contains two kinds of frequencies of 900MHz and 1800MHz.GSM can arrange in pairs or groups, and (Wireless Application Protocol WAP), reaches the function of transfer of data to wireless application communication protocol, but under the available transmitting bandwidth condition of GSM, the transmission rate of WAP online is slow, and must charge with service time, and the price of online is too high.GPRS is the value added service based on a kind of non-voice of GSM, allows the user can pass through existing mobile communication network, the information of access various places more quickly.CDMA is a kind of access mode of demal multitask, mainly is all subscriber signals in the same channel are stacked togather, and is to reach the purpose of sharing same frequency range, all better than GSM in communication quality, transmission speed and fail safe.PHS is the Digital Cellular System of Japan's research and development design, has high speed Internet access, advantages such as high definition words matter, cheap rate and low electromagnetic wave.
From the above, mobile communication system of a great variety, mobile phone then must use identical communication protocol with mobile communication system, could get in touch by mobile communication system, for instance, suppose that the mobile communication dealer provides the communication system of gsm protocol, then must use the mobile phone of GSM type just can converse.Yet the communication protocol that is adopted is had nothing in common with each other all over the world, and for example GSM is adopted in Europe, and the U.S. adopts CDMA, and Japan adopts PHS.Dual-mode handset refers to the mobile phone that can support two kinds of communication protocols simultaneously, for example can under gsm system and cdma system, communicate by letter, or can communicate by letter under gsm system and PHS system, so dual-mode handset is very convenient for the user who does much traveling all over the world.
At present the design of dual-mode handset is that circuit with two kinds of communication protocols designs together in mobile phone inside, yet this design can make the circuit of mobile phone inside and the degree of difficulty of wires design increase, and also can be subjected to bigger restriction on the mechanism design of mobile phone.In addition, the price of dual-mode handset is higher, and two kinds of communication protocols of dual-mode handset can not freely be selected by the user, thus the direct mobile phone of two different communication protocol of purchase of some user, and can not choose dual-mode handset.Yet, because the user may use two mobile phones to bring inconvenience with data storing such as address book/calendars in mobile phone.
Summary of the invention
Therefore main purpose of the present invention is to provide a kind of dual mode communication device, and its power module can be installed on this mobile phone removably, and the radio communication of this another specification of mobile phone is provided, and makes this mobile phone become dual-mode handset, to address the above problem.
A kind of power module of mobile phone is provided in the preferred embodiment of the present invention, and this mobile phone provides the radio communication of one first specification, and this power module can be installed on this mobile phone removably, and this power module comprises a housing; One battery is installed in this housing, is used to provide the power supply of this mobile phone; One radio circuit is installed in this housing, is used for changing radiofrequency signal and baseband signal, so that a radio communication that differs from second specification of this first specification to be provided; One baseband circuit is connected in this radio circuit, is used for handling baseband signal; One antenna is installed in this housing, is used for emission and received RF signal and an internal memory, is installed in this housing, is used for storage data.Wherein this radio circuit comprises a radio frequency receiver and a radiofrequency launcher, and this radio frequency receiver is used for radiofrequency signal is converted to baseband signal, and this radiofrequency launcher is used for baseband signal is converted to radiofrequency signal.In addition, this power module can also be used for being connected with computer, as the interface of this computer radio online.
