The utility model specifically provides a kind of two-mode mobile phone system, its structure comprises: a primary module, the baseband chip that comprises the mobile phone signal that is used to handle a kind of standard, radio frequency chip and peripheral hardware, software comprises the MMI module of this standard mobile phone, protocol module, driver module and interface parsing module, the interface display module that also comprises this dual-mode handset, the key response module; One from module, comprises the baseband chip of the mobile phone signal that is used to handle another kind of standard, and radio frequency chip and peripheral hardware, software comprise the MMI module of this standard mobile phone, protocol module, driver module and interface parsing module; It is characterized in that: primary module and move in relatively independent mode from module, and between be connected with two data signal lines by two control signal wires, communicate and data interaction, be specially: the delivery outlet I/OM1 of primary module links to each other with input port I/OS1 from module by control signal wire M-READY; Link to each other with primary module input port I/OM2 by control signal wire S-READY from the delivery outlet I/OS2 of module; The output pin TXM of the full duplex serial ports UARTM of primary module is connected with input pin RXS from the full duplex serial ports UARTS of module by data wire; The input pin RXM of the full duplex serial ports UARTM of primary module is connected with output pin TXS from the full duplex serial ports UARTS of module by data wire.
3) beneficial effect:
This programme interface is simple and reliable, and it is comparatively convenient that software is realized, main control module with have suitable independence from the control module, and adopt comparatively general AT interface, have strong versatility.
Description of drawings
Fig. 1 is a two-mode mobile phone system structure chart of the present utility model.
Embodiment
Scheme Design figure is as shown in Figure 1:
I/OM1 is a delivery outlet, and main control module is used for notice from the control module, and current main control module has been ready to receive data;
I/OM2 is the input port, from the control module be used to notify main control module, current from the control module be ready to receive data, after main control module is notified, begin to send data;
UARTM be main control module with from the control module communication with wake the full duplex serial ports of usefulness up, be used to receive and dispatch AT order and wake module.
TXM is a delivery outlet, is used for primary module and gives and to wake up when module sends data from module and transmission interface order data to from module.
RXM is the input port, is used for waking up module and transmission interface order data to primary module when module sends data to primary module.
I/OS1 is the input port, main control module be used for the notice from the control module, current main control module has been ready to receive data, from the control module notified after, begin to send data;
I/OS2 is a delivery outlet, from the control module be used to notify main control module, current from the control module be ready to receive data;
UARTS be main control module with from the control module communication with wake the full duplex serial ports of usefulness up, be used to receive and dispatch AT order and wake module.
TXS is a delivery outlet, is used for waking up primary module and transmission interface order data to primary module when module sends data to primary module.
RXS is the input port, is used for primary module and gives and to wake up when module sends data from module and transmission interface order data to from module.
Main control module need be realized needed all application functions of mobile phone, and hardware comprises a needed baseband chip of complete mobile phone, radio frequency chip and other all peripheral hardwares that need, and software comprises complete MMI, agreement, modules such as driving and the parsing of AT interface; From controlling the agreement that module mainly realizes standard that this module is supported, communication function, hardware mainly comprise master chip, radio frequency chip, and the necessary flash of system's operation, and peripheral hardwares such as sram, software comprise the parsing of AT interface, agreement, modules such as driving.
Primary module and move in relatively independent mode from module, primary module removes and finishes the necessary communication function of this standard mobile phone, beyond the phonecard management function, also need finish interface display, key response and some other additional application function; Fairly simple from the module software and hardware structure, mainly finish necessary communication function of this standard mobile phone and phonecard management function.
The system that such bimodulus piece constitutes can be by only opening primary module or opening primary module simultaneously and reach the purpose of supporting a kind of standard network or two kinds of standard networks simultaneously from module.
If only need support the network formats that primary module is supported, can only open primary module during system boot, not open from module, this moment, mobile phone ran on the single mode mobile phone state.
If only need support from the network formats of module support or need support two kinds of network formats simultaneously, primary module need be opened simultaneously and from module, this moment is two modules independent operating separately most of the time, standby simultaneously, have only when primary module need obtain from the information of module or from module the semaphore that initiatively reports is arranged, incoming call is when coming operation such as note, two module generation communications and data interaction, and show the work at present state by primary module.Data interaction takes place in two modules on control signal shown in Figure 1 and data-interface.Main control module with from the control module link to each other with data-interface by simple signaling interface.
Situation 1: the pattern of only opening main control module
Step 1: the mobile phone start that powers on, open main control module.
Step 2: main control module is not opened from the control module according to current power on mode.
Step 3: main control module is finished the software and hardware initialization, opens agreement, open with network side enter holding state alternately.
Situation 2: open simultaneously main control module and from the control module pattern
Step 1: mobile phone powers on, and main control module is opened in start.
Step 2: main control module is according to current power on mode, and control is given from the control module and powered on, and starts from the control module.
Step 3: connect step 2, main control module and carry out own software and hardware initialization separately from the control module, if current phone be set to only support from controlling module institute network enabled standard, main control module do not start this module protocol and with network side alternately; Finish the software and hardware initialization of this module and start agreement from the control module, startup is mutual with network side.
Step 4: connect step 3, main control module and from the control module initialization procedure, carry out data interaction by control interface and data-interface, carrying out communication, finish interface display and peripheral components management by main control module.Step 5: connect step 2, main control module and carry out own software and hardware initialization separately from the control module, if current phone is set to support simultaneously two kinds of standard networks, two modules need the agreement of each this module of self-starting, and startup and network side alternately.
Step 6: connect step 3, main control module and from the control module initialization procedure, carry out data interaction by control interface and data-interface, carrying out communication, finish interface display and peripheral components management by main control module.
