Description
Technical field
The invention belongs to the technical field of portable terminal, more particularly relate to possess mobile communication, all multi-functional terminal installations such as wireless Internet access.
Background technology
The development of mobile radio terminal is at present maked rapid progress, and to the up-to-date smart mobile phone that has wireless networking capabilities, the function of mobile radio terminal from strength to strength from the initial mobile phone that only satisfies the telephone relation function.But the problem of the inconvenience of following power and coming is exactly the expansion of mobile radio terminal volume and weight, is difficult to carry.
In order to satisfy the needs of diverse network and demonstration, the high-resolution screen of large scale is the present requisite configuration of Multi-featured Mobile Terminal, various additional equipments, bluetooth for example, infrared, expansion card, alphabetic keypad, stereo speaker, fingerprint identification device small harddisk even all become the indispensability configuration of advanced wireless portable terminal.
Because the increase of various functions, comprise the desired network functions of 3G mobile communication terminal such as supporting video telephone, cause the power consumption of portable terminal sharply to rise, so the battery capacity of advanced wireless portable terminal increases immediately, just cause increasing considerably of battery volume.
The development trend of the integrated multifunction of present this portable terminal, feasible volume weight with mobile radio terminal of power constantly increases, broken through the acceptable scope of " moving " terminal gradually, the user feels very inconvenient for the heavy weight portable terminal of the large volume that need carry at any time, the use of justing think has the user of above-mentioned Multi-featured Mobile Terminal, when calling the how in a rush bulky mobile radio terminal of from briefcase, drawing out, because fail to lay down in the pocket; Be the sight of what kind of embarrassment when making a phone call, fat person's smart mobile phone covers more than half face of opening.And the appearance and modeling of the portable terminal of multi-functional large volume can't reach the small and exquisite stage of the desirable exquisiteness of consumer far away.
But small and exquisite on portability of carrying for portable terminal and the external form, the user enjoys the mobile communication constantly access network whenever and wherever possible that brings of the new technology of development and other new business application function thereof with regard to having no idea, if the user can't use several network applications, also just can't realize and unrestricted high efficiency to finish various affairs anywhere.
The existing problem of present portable terminal be exactly functional and portability between contradiction.If the user wishes that portable terminal is convenient to carry, and is light small and exquisite, just be difficult to accomplish powerful.If the user wishes that portable terminal has comprehensive application function, then be difficult to accomplish light small and exquisite, be easy to carry, along with the development of 3G (Third Generation) Moblie, increased increasing new function on the portable terminal and used, so the contradiction between functional and the portability is just more and more outstanding.
Summary of the invention
Purpose of the present invention, just be to overcome present Multi-featured Mobile Terminal powerful along with function, portable and the functional contradiction that becomes increasingly conspicuous of the portable terminal that is caused, a kind of split type portable terminal is provided, comprise embedded Mini mobile phone and mobile terminal host, when mobile call, it is two that split type portable terminal can change one, only use the embedded Mini mobile phone of small volume and less weight itself just can finish the needs of mobile call, when using network application, during functions such as video playback, split type portable terminal can unite two into one, embedded Mini mobile phone and mobile terminal host couple together by standard interface, can support mobile network's various new business functions.
In order to achieve the above object, the split type portable terminal of the present invention comprises embedded Mini mobile phone, and the separated wireless mobile terminal host that is connected with embedded Mini mobile phone by standard communication.
Embedded Mini mobile phone comprises radio frequency unit, the signal of the received RF unit transmission Base Band Unit that the line number word code is handled of going forward side by side, the audio frequency input-output equipment, keyboard, display screen and the memory that are connected with Base Band Unit, be connected battery unit with power supply with above-mentioned various piece, and the communication interface that is connected with mobile terminal host.
Mobile terminal host comprises application processor, the camera that is connected with application processor, bluetooth, keyboard, display screen and memory, and with the interface of embedded Mini mobile communication.
Wherein standard communication comprises serial ports and USB interface.
Mobile terminal host is furnished with jumbo battery, can pass through USB interface, to embedded Mini cell-phone charging.
Split type portable terminal can be supported the mobile network of different mode by changing the embedded Mini mobile phone of supporting the heterogeneous networks pattern.
Use the split type portable terminal among the present invention, embedded Mini mobile phone itself can be finished all functions of mobile call, can provide the editor of network function and multimedia file to play again for it after being embedded into mobile terminal host.The superiority of this technical scheme is that can change one to split type portable terminal neatly according to user's actual use needs is two or unites two into one, the portability that has promptly possessed portable terminal, the powerful application function that has possessed portable terminal has again reached the coordination between the functional and mobility of portable terminal perfectly.
For the 3G network epoch, the present invention has bigger meaning, because the difference of the standard system of 3G (Third Generation) Moblie, so the 3G portable terminal is also divided into different standards.And employing the present invention only needs a mobile terminal host, just can be arbitrarily at WCDMA/GSM, and CDMA2000/CDMA1x roams between the TD-SCDMA network.Simultaneously, any mobile network's upgrading only needs upgrading Mini mobile phone itself to get final product.And Mini mobile phone itself is owing to only finish the function of mobile call, and it is very little that volume can be accomplished, cost is very low.
