Description
Technical field
The present invention relates to communication technique field, particularly relate to a kind of slave cell phone based on the radio communication of RF-SIM card internal short-range.
Background technology
Mobile phone has been widely used in the daily life as a kind of means of communication commonly used, in today of market economy fast development, people utilize mobile phone to carry out the contact of commercial exchange, professional contacts or doings, we can say that mobile phone has become the indispensable essential articles for use of institute in people's daily life in fact, and be the necessity of carrying.And in the personnel of contact that mainly do business, the phenomenon that disposes two mobile phones is not rarely seen, why uses two mobile phones mainly still professional convenient in order to get in touch, therefore, in actual use, in two mobile phones wherein one one be main mobile phone, another one is assistant's machine, main mobile phone is as mobile phone commonly used, assistant's machine is as standby mobile phone, though two mobile phones have the branch of primary and secondary in the use,, the function of two mobile phones is basic identical.The configuration of existing this major and minor mobile phone exists following drawback: the one, cause the waste in the use, though assistant's machine seldom uses, but assistant's machine also is a mobile phone with complete function of use, many functions of use of assistant's machine be to use in actual use less than, so just caused the use waste of assistant's machine; The 2nd, can not form effective collocation of main mobile phone, assistant's machine, cause the inconvenience in the use, use and be inconvenient to be mainly reflected in three aspects: first aspect comes electrotransfer convenient inadequately, because major and minor mobile phone has been arranged, usually all the incoming call of assistant's machine can be transferred on the main mobile phone by the communication network of mobile operator, receive calls with main mobile phone, but, when if main mobile phone is being conversed, the phone of assistant's machine just can not shift success, the user also must just can know the telephone number of dialling in by checking the caller identification of assistant's machine; Second aspect is that short message can not realize sharing, when short message is when issuing assistant's machine, on main mobile phone, can't see, this moment, the user must just can view the content of short message by assistant's machine, was seeing on the main mobile phone then the short message of the assistant's machine communication network by mobile operator must be dealt on the main mobile phone if think; The third aspect is that cell-phone telephone book can not duplicate mutually easily, telephone directory is the important tool that the cellie carries out business relations, for personnel based on the business of getting in touch, the value of its cell-phone telephone book is much larger than mobile phone itself, when the telephone directory on the main mobile phone will copy on assistant's machine, need copy to the telephone directory of main mobile phone in the computer earlier, and then the main cell-phone telephone book in the computer copied on assistant's machine, very inconvenient, equally, it also is like this telephone directory on assistant's machine being copied on the main mobile phone.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of slave cell phone based on the radio communication of RF-SIM card internal short-range is provided, the assistant's machine that is used as the main mobile phone that is inserted with the RF-SIM card uses, can really play the effect of association from main mobile phone, and have characteristics cheap, easy to use, that result of use is good, can also wait as life information collector, tag card, TV remote controller simultaneously and use, have the characteristics of a tractor serves several purposes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of slave cell phone based on the radio communication of RF-SIM card internal short-range comprises housing; Housing is provided with display screen and several buttons; Housing is provided with the battery mounting groove that is used for holding battery; Circuit board is housed in the housing; Circuits System is housed in the circuit board; Circuit board is provided with and is used for the power interface of power supply being provided and being used to provide the deck of grafting SIM cards of mobile phones to Circuits System; This power interface coupling is in described battery mounting groove; Circuits System comprises base band and cell phone system platform, be used for being matched with the button circuits for triggering of button, be used for driving display driver circuit that screen shows, be used for being matched with antenna for mobile phone to realize the main RF unit of communication network signal transmitting and receiving, the output of button circuits for triggering is connected to base band and cell phone system platform, the output of base band and cell phone system platform is connected to display driver circuit, and base band and cell phone system platform are connected with main RF unit; Include the basic handling module that can be used for realizing mobile phone communication and receiving short message function in base band and the cell phone system platform;
