1) coverage rate of TD-SCDMA and WCDMA network is comprehensive inadequately.
2) under the metastable situation of 3G mobile number of users, 3G operator wants the ownership, strives for that part WCDMA/TD-SCDMA user forwards the TD-SCDMA/WCDMA network to, to satisfy basic operation needs.And 3G subscription is to the migration of other 3G network the time, and owing to multiple reason generally is not eager to abandon its original number, but more hope can be answered WCDMA and TD-SCDMA number simultaneously, selects WCDMA and TD-SCDMA to make a call as caller as required simultaneously;
3) use the user of TD-SCDMA and WCDMA network more to wish on a mobile phone, to realize the communication function of TD-SCDMA and WCDMA simultaneously, rather than carry the mobile phone of two single systems.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of TD-SCDMA/WCDMA dual-mode and dual-idle mobile phone, realizes the standby simultaneously of TD-SCDMA and WCDMA module, can connect respectively to make a phone call and receive and dispatch note in TD-SCDMA and WCDMA network.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of dual-mode and dual-idle mobile phone, comprise man-machine interface, display, keyboard, memory, loud speaker, microphone, charging module, also comprise two mobile phone terminal modules, analog switch, two cover radio-frequency modules, described terminal module comprises WCDMA module, TD-SCDMA module, and described radio-frequency module comprises WCDMA radio-frequency module, TD-SCDMA radio-frequency module;
Wherein a terminal module is connected, and is connected with loud speaker, microphone by analog switch with described man-machine interface, display, keyboard, memory, charging module, its respective radio-frequency part direct circuit;
Another terminal module is connected with last terminal module by UART (universal asynchronous reception/transmitter) serial ports, and is connected with its respective radio-frequency part direct circuit with analog switch respectively.
Wherein, described analog switch is the binary channels analog switch.
Wherein, described WCDMA module is connected with the WCDMA radio-frequency module, and described TD-SCDMA module is connected with the TD-SCDMA radio-frequency module.
The utlity model has following beneficial effect: simultaneously integrated TD-SCDMA and two kinds of mobile phone terminal modules of WCDMA in the utility model mobile phone, two modules are come mutual communication by serial ports AT order, resource-sharing and the state of having realized dual-mode handset are mutual, standby in TD-SCDMA and two kinds of standard networks of WCDMA simultaneously, can in TD-SCDMA and WCDMA network, connect respectively and make a phone call and receive and dispatch note, and because a shared cover cell phone system public resource has reduced cost.

Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model is integrated in two terminal modules of TD-SCDMA, WCDMA in the mobile phone, allows the user to use under two kinds of different network environments of TD-SCDMA/WCDMA, is called the TD-SCDMA/WCDMA dual-mode and dual-idle mobile phone, is called for short dual-mode handset.
This dual-mode handset comprises man-machine interface, LCD display unit, keyboard, memory, loud speaker, microphone, charging module, also comprises mobile phone terminal module, analog switch, two cover radio-frequency modules.Terminal module comprises WCDMA module, TD-SCDMA module, and radio-frequency module comprises WCDMA radio-frequency module, TD-SCDMA radio-frequency module.Wherein a terminal module is connected, and is connected with loud speaker by analog switch with described man-machine interface, display, keyboard, memory, charging module, its respective radio-frequency part direct circuit; Another terminal module is connected with last terminal module by the UART serial ports, and is connected with its respective radio-frequency part direct circuit with analog switch respectively.
Wherein, the shared cover common system resource of TD-SCDMA and WCDMA terminal module is as keyboard, LCD display, memory, loud speaker, microphone, Midi/Mp3 etc., to reduce cost; With TD-SCDMA module or WCDMA module as main control module, another module as controlled module, main control module is to the management and the allotment of above-mentioned whole system public resource.
The TD-SCDMA module links to each other by the UART serial ports with the WCDMA module, between data transmit with the form of AT order by this UART serial ports.Main control module can receive the communication state information that controlled module is passed back by the UART serial ports by real time monitoring, directly controls the binary channels analog switch and carries out the passage switching.Wherein, the UART serial ports is mainly used in main control module and controlled module is carried out the state communication, can define a cover and be specifically designed to the agreement that WCDMA and TD-SCDMA module are carried out communication, can do respective handling according to the concrete content of coming that passes of serial ports at the software of main control module side, such as: can and on LCD, show simultaneously etc. by the pronunciation of the loud speaker on the main control module when on LCD, showing the power of controlled module network signal, controlled module network incoming call.
This mobile phone has adopted two cover radio frequencies, an one cover WCDMA radio frequency and a cover TD-SCDMA radio frequency, realize that respectively the power that monitors and detect WCDMA and two kinds of different frequency baseband signals of TD-SCDMA automatically changes, and can receive and send WCDMA and two kinds of different frequency baseband signals of TD-SCDMA respectively, realize the standby simultaneously of WCDMA and TD-SCDMA module and in WCDMA and TD-SCDMA network, connect respectively making a phone call and receiving and dispatching note.
As shown in Figure 3, in the present embodiment, system's public resource comprises keyboard, LCD display, loud speaker, microphone, memory, Charge Management analog circuit interface, Midi/Mp3, with the WCDMA module as main control module, be responsible for the management and the allotment of above-mentioned whole system public resource: to the WCDMA encoding and decoding speech, channel coding/decoding, encrypt and decrypt, balanced, to various voice, the digital information modulation, amplify, emission, receive, demodulation, realize the output of Midi/MP3 music, man-machine interface (button input) is provided, backlight, the SIM card interface is provided, realization provides data equipment to the storage and the charging controlled function of telephone number, earphone, the interface of external equipments such as charger.
When the user carried out the mobile phone use at the WCDMA network function by this dual-mode handset, because the WCDMA module is a main control module in the system, mobile phone was equal to an independently WCDMA mobile phone under this mode.
When the user uses the TD-SCDMA network of this dual-mode handset to carry out the mobile phone use, the input information of mobile phone key is passed to the WCDMA module earlier and is handled, the WCDMA module is passed to TD-SCDMA module by the UART serial ports with the form of AT order with the keypad information that obtains, the TD-SCDMA module is handled the AT order analysis that receives again, and this moment, the TD-SCDMA module was equal to an independently TD-SCDMA mobile phone.In the whole process of TD-SCDMA module work, the WCDMA main control module can receive the communication state information that the TD-SCDMA module is passed back by the UART serial ports by real time monitoring, and analyze demonstration, wherein, the switching of the voice-frequency channel of the loud speaker of WCDMA and TD-SCDMA module, microphone is that the WCDMA module is controlled by analog switch.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
