Wherein, switch control module, card 1 protocol stack module, card 2 protocol stack modules and baseband processing module are included in mobile phone base band chip.
First, switching over module can be under the driving of switch control module, constantly cyclic switching between RF1-base band/RF2-base band two passes, switching time is adjustable, i.e. and the conducting of RF1-base band, turn-off time (shutoff of corresponding RF2-base band, ON time) can optionally be adjusted.
The meeting such as the transmitting-receiving request of SIM card 1 and data, when RF1-base band is opened, is carried out relevant treatment jointly by baseband processing module and card 1 protocol stack module like this; Transmitting-receiving request and the data of SIM card 2, when RF2-Baseband Channel is opened, carry out relevant treatment jointly by baseband processing module and card 2 protocol stack modules.Guarantee that SIM card 1, card 2 incoming call, dialing, call etc. all have an opportunity to process to base band, there will not be and while wherein coming electricity, monopolize radio frequency-baseband interface, and cause another road to answer or to call, realize the dual-card dual-standby dual-pass of mobile phone.
Particularly, as shown in Figure 3, the two situations about treating of corresponding mobile phone two-card, in above-mentioned steps S102, by switching over module, with predetermined period cyclic switching between described two radio-frequency channels, the step of carrying out the double-card dual-standby of mobile terminal comprises:
Step S1021, judges current the first radio-frequency channel or the second radio-frequency channel of switching to according to predetermined switching cycle; If switch to the first radio-frequency channel, enter step S1022; Otherwise, enter step S1024;

Take mobile phone as example, in the present embodiment, switching over module is under the driving of switch control module, constantly cyclic switching between RF1-base band, RF2-base band two passes, switching time is adjustable, i.e. the conducting of RF1-Baseband Channel, turn-off time (shutoff of corresponding RF2-Baseband Channel, ON time) can optionally be adjusted.
Corresponding RF1-Baseband Channel conducting phase:
First, at switch control module driving switch handover module, when RF1-Baseband Channel is opened, switch control module is understood synchronization notice baseband processing module, requires transmitting-receiving request and the related data of baseband processing module monitoring, treatment S IM card 1.So this stage SIM card 1 is in holding state, now SIM card 2 wait states;
Corresponding RF2-Baseband Channel conducting phase:
When switching cycle arrives, switch control module driving switch handover module, is switched to RF2-base band path and opens, and Simultaneous Switching control module is notified baseband processing module, requires transmitting-receiving request and the related data of baseband processing module monitoring, treatment S IM card 2.So this stage SIM card 2 is in holding state, 1 of SIM card forwards wait state to;
Follow-up, RF1-Baseband Channel conducting phase for the second time:
When being switched to for the second time RF1-base band path and opening to switching over module, SIM card 1 holds over baseband processing module, and SIM card 1 is in holding state;
RF2-base band conducting phase for the second time:
Until state switches arrival next time, when RF2-base band path is opened, SIM card 2 is in holding state.
According to above-mentioned principle, switching over module is cyclic switching between RF1-base band, two paths of RF2-base band constantly, realizes the double-card dual-standby of SIM card 1 and SIM card 2.
As shown in Figure 4, the situation of corresponding mobile phone two-card bilateral, in above-mentioned steps S102, by switching over module, with predetermined period cyclic switching between described two radio-frequency channels, the step of carrying out the double card bilateral of mobile terminal comprises:
Step S1021, judges current the first radio-frequency channel or the second radio-frequency channel of switching to according to predetermined switching cycle; If switch to the first radio-frequency channel, enter step S1022; Otherwise, enter step S1024;
Step S1022, control switch handover module conducting the first radio-frequency channel, turn-offs the second radio frequency conducting;
Step S1023, transmitting-receiving request and the related data that described first terminal card sends through the first radio-frequency channel monitored, transmits and processed to notice baseband processing module; Described first terminal card is in holding state, and the second terminal card is in wait state;
Step S1026, when described first terminal card has incoming call or dialing, the call request of described first terminal card is processed jointly by the protocol stack module of baseband processing module and this first terminal card; If incoming call or dial-up, first terminal card enters talking state; Return to step S1021.
Step S1024, control switch handover module turn-offs the first radio-frequency channel, conducting the second radio frequency conducting;
Step S1025, transmitting-receiving request and the related data that described the second terminal card sends through the second radio-frequency channel monitored, transmits and processed to notice baseband processing module; Described the second terminal card is in holding state, and first terminal card is in wait state;
Step S1027, when described the second terminal card has incoming call or dialing, the call request of described the second terminal card is processed jointly by the protocol stack module of baseband processing module and this second terminal card; If incoming call or dial-up, described the second terminal card is in talking state; Return to step S1021.
The situation of corresponding mobile phone two-card bilateral, as a same reason, switching over module under the driving of switch control module, constantly cyclic switching between RF1-base band, two paths of RF2-base band:
RF1-Baseband Channel opening stage:
First, switching over module, under the driving of switch control module, opens RF1-Baseband Channel, and switch control module can be notified baseband processing module simultaneously, the transmitting-receiving request and the related data that require baseband processing module monitoring, transmission, treatment S IM card 1, now SIM card 1 is in holding state.
When SIM cards of mobile phones 1 has incoming call, the call request of SIM card 1 can be processed jointly by baseband module and card 1 protocol stack module.If user selects to connect the incoming call of SIM card 1, baseband processing module starts communicating data of processing SIM card 1 etc., so SIM card 1 is in talking state;
Corresponding RF2-base band path opening stage:
When switching cycle arrives, switch control module driving switch handover module, being switched to RF2-Baseband Channel opens, and switch control module is notified baseband processing module simultaneously, the transmitting-receiving request and the related data that require baseband processing module monitoring, transmission, treatment S IM card 2, now SIM card 2 is in holding state.
Whether now, can detect SIM card 2 has incoming call or whether has dialing.If without incoming call, without dialing, SIM card 2 maintains holding state; If have incoming call or have dialing, can select to enter talking state, or hang up or select short-message sending to calling party " just in phone, after a while reply " etc.This stage SIM card 1, in wait state, is waited for next time and is switched and arrive.
Follow-up, RF1-Baseband Channel opening stage for the second time:
When switching over module switches to for the second time RF1-Baseband Channel and opens by the time, SIM card 1 takies baseband processing module again, and baseband processing module can continue the communicating data for the treatment of S IM card 1;
RF2-base band path opening stage for the second time:
Similarly, when RF2-Baseband Channel is opened for the second time, baseband processing module can continue the relevant communication data for the treatment of S IM card 2 etc.
So constantly cyclic switching goes down successively.So in the different time periods, the call of SIM card 1 and SIM card 2 can obtain timely, complete processing, thereby realizes double card bilateral.
Due to constantly cyclic switching between RF1-base band, two paths of RF2-base band of switch control module driving switch handover module, while so just having avoided a card incoming call, the radio frequency of this card is monopolized radio frequency-baseband interface, cause another card cannot converse process problem occur, thereby realized two-way radio frequency, add a base band, reach the object of dual-card dual-standby dual-pass.
The present embodiment passes through such scheme, use a set of base band to add on two cover radio frequencies and the shared platform of base band-radio frequency interface, by add switching over module on radio frequency-baseband interface, allow two-way independence radio-frequency module recycle respectively, discharge baseband module, avoid a road to monopolize radio frequency-baseband interface (monopolizing base band), thereby realize the dual-card dual-standby dual-pass of mobile phone, not only improved base-band resource utilance, and promoted that user experiences and the practicality of double-card mobile phone, compared to existing technology, it is simpler on software is processed, stability is higher, on cost, more have superiority, and saving arrangement space, power consumption is less, heating still less.

Switch unit 5021, for control switch handover module conducting the first radio-frequency channel, turn-offs the second radio frequency conducting; And when switching cycle arrives, control switch handover module turn-offs the first radio-frequency channel, conducting the second radio frequency conducting;
Notification unit 5022, for notifying baseband processing module to monitor and process transmitting-receiving request and related data that described first terminal card sends through the first radio-frequency channel; Described first terminal card is in holding state, and the second terminal card is in wait state; And when switching cycle arrives, transmitting-receiving request and the related data that described the second terminal card sends through the second radio-frequency channel monitored and processed to notice baseband processing module; Described the second terminal card is in holding state, and first terminal card is in wait state.
Take mobile phone as example, in the present embodiment, switching over module is under the driving of switch control module, constantly cyclic switching between RF1-base band, RF2-base band two passes, switching time is adjustable, i.e. the conducting of RF1-Baseband Channel, turn-off time (shutoff of corresponding RF2-Baseband Channel, ON time) can optionally be adjusted.
Corresponding RF1-Baseband Channel conducting phase:
First, at switch control module driving switch handover module, when RF1-Baseband Channel is opened, switch control module is understood synchronization notice baseband processing module, requires transmitting-receiving request and the related data of baseband processing module monitoring, treatment S IM card 1.So this stage SIM card 1 is in holding state, now SIM card 2 wait states;
Corresponding RF2-Baseband Channel conducting phase:
When switching cycle arrives, switch control module driving switch handover module, is switched to RF2-base band path and opens, and Simultaneous Switching control module is notified baseband processing module, requires transmitting-receiving request and the related data of baseband processing module monitoring, treatment S IM card 2.So this stage SIM card 2 is in holding state, 1 of SIM card forwards wait state to;
Follow-up, RF1-Baseband Channel conducting phase for the second time:
When being switched to for the second time RF1-base band path and opening to switching over module, SIM card 1 holds over baseband processing module, and SIM card 1 is in holding state;
RF2-base band conducting phase for the second time:
Until state switches arrival next time, when RF2-base band path is opened, SIM card 2 is in holding state.
According to above-mentioned principle, switching over module is cyclic switching between RF1-base band, two paths of RF2-base band constantly, realizes the double-card dual-standby of SIM card 1 and SIM card 2.
Further, the situation of corresponding mobile phone two-card bilateral, described notification unit 5022 is also for have incoming call or when dialing when described first terminal card, the call request of first terminal card described in the protocol stack module co-treatment of notice baseband processing module and this first terminal card; If incoming call or dial-up, first terminal card enters talking state.
Described notification unit 5022 is also for have incoming call or when dialing when described the second terminal card, the call request of the second terminal card described in the protocol stack module co-treatment of notice baseband processing module and this second terminal card; If incoming call or dial-up, described the second terminal card is in talking state.
The situation of corresponding mobile phone two-card bilateral, as a same reason, switching over module under the driving of switch control module, constantly cyclic switching between RF1-base band, two paths of RF2-base band:
RF1-Baseband Channel opening stage:
First, switching over module, under the driving of switch control module, opens RF1-Baseband Channel, and switch control module can be notified baseband processing module simultaneously, the transmitting-receiving request and the related data that require baseband processing module monitoring, transmission, treatment S IM card 1, now SIM card 1 is in holding state.
When SIM cards of mobile phones 1 has incoming call, the call request of SIM card 1 can be processed jointly by baseband module and card 1 protocol stack module.If user selects to connect the incoming call of SIM card 1, baseband processing module starts communicating data of processing SIM card 1 etc., so SIM card 1 is in talking state;
Corresponding RF2-base band path opening stage:
When switching cycle arrives, switch control module driving switch handover module, being switched to RF2-Baseband Channel opens, and switch control module is notified baseband processing module simultaneously, the transmitting-receiving request and the related data that require baseband processing module monitoring, transmission, treatment S IM card 2, now SIM card 2 is in holding state.
Whether now, can detect SIM card 2 has incoming call or whether has dialing.If without incoming call, without dialing, SIM card 2 maintains holding state; If have incoming call or have dialing, can select to enter talking state, or hang up or select short-message sending to calling party " just in phone, after a while reply " etc.This stage SIM card 1, in wait state, is waited for next time and is switched and arrive.
Follow-up, RF1-Baseband Channel opening stage for the second time:
When switching over module switches to for the second time RF1-Baseband Channel and opens by the time, SIM card 1 takies baseband processing module again, and baseband processing module can continue the communicating data for the treatment of S IM card 1;
RF2-base band path opening stage for the second time:
Similarly, when RF2-Baseband Channel is opened for the second time, baseband processing module can continue the relevant communication data for the treatment of S IM card 2 etc.
So constantly cyclic switching goes down successively.So in the different time periods, the call of SIM card 1 and SIM card 2 can obtain timely, complete processing, thereby realizes double card bilateral.
Due to constantly cyclic switching between RF1-base band, two paths of RF2-base band of switch control module driving switch handover module, while so just having avoided a card incoming call, the radio frequency of this card is monopolized radio frequency-baseband interface, cause another card cannot converse process problem occur, thereby realized two-way radio frequency, add a base band, reach the object of dual-card dual-standby dual-pass.
The present embodiment passes through such scheme, use a set of base band to add on two cover radio frequencies and the shared platform of base band-radio frequency interface, by add switching over module on radio frequency-baseband interface, allow two-way independence radio-frequency module recycle respectively, discharge baseband module, avoid a road to monopolize radio frequency-baseband interface (monopolizing base band), thereby realize the dual-card dual-standby dual-pass of mobile phone, not only improved base-band resource utilance, and promoted that user experiences and the practicality of double-card mobile phone, compared to existing technology, it is simpler on software is processed, stability is higher, on cost, more have superiority, and saving arrangement space, power consumption is less, heating still less.
