In this embodiment, a set of baseband plus two sets of RF channels and a baseband-radio interface are shared, and the dual-card dual-standby dual-pass function of the mobile phone is realized.

Step S102: The dual-card dual-standby dual-pass of the mobile terminal is performed by cyclically switching between the two radio frequency channels by using a switch switching module.

In order to realize the dual-card dual-standby dual-pass function of the mobile phone, a switch switching module is added to the interface signals of the baseband and the two RF channels (the switch switching module can be an analog switch, but not limited to an analog switch), continuously in the RF1- The baseband and the RF2-baseband are switched between the two paths, and the baseband is multiplexed to prevent the baseband from being monopolized when a call is made, thereby implementing dual-card dual-standby dual-pass.

Specifically, the system framework involved in the method operation environment of this embodiment is shown in FIG. 2, and includes: an RF1 module, an RF2 module; a switch switching module; a switch control module; a SIM card 1 module, a SIM card 2 module; and a card 1 protocol stack. Module, card 2 protocol stack module; baseband processing module; each module function description is as follows:

(1) RF1 module, RF2 module. That is, the aforementioned two-way radio frequency chip and related radio frequency path. It is used for transmitting and receiving RF signals and data transmission with baseband. The RF1 module corresponds to the SIM card 1, and the RF2 module corresponds to the SIM card 2;

(2) Switch switching module. Cyclic switching between RF1-baseband channels (RF1 module and baseband chip path) and RF2-baseband channels (RF2 module and baseband chip path);

(3) Switch control module. That is, the drive control portion of the above-described switch switching module is processed by software. The module has two functions, firstly used for state control and driving of the switch switching module. Secondly, the baseband processing module is synchronously notified, and the card path is opened at a specific moment. With the processing module, which card data should be processed at the moment, etc.;

(4) SIM card 1 module, SIM card 2 module. For each independent identity module, SIM card 1 module corresponds to SIM card 1, SIM card 2 module corresponds to SIM card 2;

(5) Card 1 protocol stack module, card 2 protocol stack module. They are separate protocol processing modules for their respective protocol processing. Card 1 protocol stack module corresponds to SIM card 1, card 2 protocol stack module corresponds to SIM card 2;

(6) Baseband processing module. Responsible for overall request processing, data transmission, processing and related control, monitoring, etc. When the switch control module switches the drive switch switching module, it also notifies the baseband processing module:

When the RF1-baseband channel is opened, the baseband processing module is required to transmit and process the receiving request and related data of the SIM card 1;

When the RF2-baseband channel is turned on, the baseband processing mode is required to transmit and process the SIM card 2 transmission and reception request and related data.

The switch control module, the card 1 protocol stack module, the card 2 protocol stack module, and the baseband processing module are all included in the baseband chip of the mobile phone.

First, the switch switching module is continuously switched between the RF1-baseband/RF2-baseband channels under the driving of the switch control module, and the switching time is adjustable, that is, the turn-on and turn-off times of the RF1-baseband (corresponding to The turn-off and turn-on time of the RF2-baseband can be adjusted as appropriate.

In this way, the sending and receiving request and data of the SIM card 1 are jointly processed by the baseband processing module and the card 1 protocol stack module when the RF1-baseband is turned on; the SIM card 2 sends and receives requests and data, when the RF2-baseband channel is opened, The baseband processing module and the card 2 protocol stack module jointly perform related processing. Ensure that the incoming calls, dialing, and calls of SIM card 1 and SIM card 2 have the opportunity to process the baseband. There will be no exclusive radio frequency-baseband interface when one of the calls is made, and the other channel cannot answer or make a call. Card dual standby dual pass.

Specifically, as shown in FIG. 3, in the case of the dual-card dual-standby of the mobile phone, in the foregoing step S102, the switch switching module periodically switches between the two RF channels by using a predetermined cycle to perform the movement. The steps of the dual card dual standby of the terminal include:

Step S1021, determining whether to switch to the first RF channel or the second RF channel according to a predetermined switching period; if switching to the first RF channel, proceeding to step S1022; otherwise, proceeding to step S1024;

Step S1022, the control switch switching module turns on the first RF channel, and turns off the second RF channel. Step S1023, the baseband processing module is notified to monitor and process the sending and receiving request and related data sent by the first terminal card via the first RF channel. The first terminal card is in a standby state, and the second terminal card is in a waiting state; after the step is performed, the process returns to step S1021.

Step S1024, the control switch switching module turns off the first RF channel, and turns on the second RF channel; Step S1025, notifying the baseband processing module to monitor and process the sending and receiving request and related data sent by the second terminal card via the second RF channel; The second terminal card is in a standby state, and the first terminal card is in a waiting state; after the step is performed, the process returns to step S1021.

Taking the mobile phone as an example, in this embodiment, the switch switching module is continuously switched between the RF1-baseband and RF2-baseband channels under the driving of the switch control module, and the switching time is adjustable, that is,

The turn-on and turn-off time of the RF1-baseband channel (corresponding to the turn-off and turn-on time of the RF2-baseband channel) can be adjusted as appropriate.

Corresponding to the RF1-baseband channel conduction phase:

First, when the switch control module drives the switch switching module to open the RF1-baseband channel, the switch control module synchronously notifies the baseband processing module, and requires the baseband processing module to monitor and process the SIM card 1 transmission and reception request and related data. Therefore, at this stage, the SIM card 1 is in the standby state, and the SIM card 2 is in the waiting state;

Corresponding to the RF2-baseband channel conduction phase:

When the switching period comes, the switch control module drives the switch switching module to switch to the RF2-baseband path to open, and the switch control module notifies the baseband processing module, and the baseband processing module is required to monitor and process the SIM card 2 transmission and reception request and related data. Therefore, at this stage, the SIM card 2 is in the standby state, and the SIM card 1 is turned to the waiting state; Subsequent, the second RF1-baseband channel conduction phase:

When the switch switching module switches to the RF1-baseband path for the second time, the SIM card 1 continues to occupy the baseband processing module, and the SIM card 1 is in the standby state;

The second RF2-baseband conduction phase:

Until the next state switch comes, the SIM card 2 is in the standby state when the RF2-baseband path is open.

According to the above principle, the switch switching module continuously switches between the two paths of RF1-baseband and RF2-baseband to realize dual card dual standby of SIM card 1 and SIM card 2.

As shown in FIG. 4, in the case of the dual-card dual-pass of the mobile phone, in the above step S102, the switch switching module periodically switches between the two radio frequency channels in a predetermined cycle, and the steps of performing dual-card dual-passing of the mobile terminal include:

Step S1022, the control switch switching module turns on the first RF channel, and turns off the second RF channel. Step S1023, notifying the baseband processing module to monitor, transmit, and process the sending and receiving request sent by the first terminal card via the first RF channel and related Data; the first terminal card is in a standby state, and the second terminal card is in a waiting state;

Step S1026: When the first terminal card has an incoming call or a dialing, the call request of the first terminal card is jointly processed by the baseband processing module and the protocol stack module of the first terminal card; if the incoming call or the dialing is connected, The first terminal card enters a call state; after the step is performed, the process returns to step S1021.

Step S1024, the control switch switching module turns off the first RF channel, and turns on the second RF channel. Step S1025, notifying the baseband processing module to monitor, transmit, and process the sending and receiving request of the second terminal card sent by the second RF channel and related Data; the second terminal card is in a standby state, and the first terminal card is in a waiting state;

Step S1027: When the second terminal card has an incoming call or a dialing, the second terminal card is connected. The request is processed by the baseband processing module and the protocol stack module of the second terminal card; if the incoming call or the dial-up is connected, the second terminal card is in a call state;

S102K

In the same way as the dual-card dual-pass mobile phone, the switch switching module is continuously switched between the RF1-baseband and RF2-baseband channels under the driving of the switch control module:

RF1-baseband channel open phase:

First, the switch switching module drives the RF1-baseband channel under the driving of the switch control module, and the switch control module notifies the baseband processing module at the same time, and requires the baseband processing module to monitor, transmit, and process the SIM card 1 transmission and reception request and related data. When the SIM card 1 is in the standby state;

When there is an incoming call on the SIM card 1 of the mobile phone, the call request of the SIM card 1 is jointly processed by the baseband processing module and the card 1 protocol stack module. If the user chooses to connect the incoming call of the SIM card 1, the baseband processing module starts to process the call data of the SIM card 1, etc., and then the SIM card 1 is in a call state; corresponding to the RF2-baseband path opening phase:

When the switching period comes, the switch control module drives the switch switching module, switches to the RF2-baseband channel to open, and the switch control module simultaneously notifies the baseband processing module, and requires the baseband processing module to monitor, transmit, and process the SIM card 2's sending and receiving request and related data. At this time, the SIM card 2 is in the standby state;

At this time, it can be detected whether the SIM card 2 has an incoming call or whether there is a dialing. If there is no incoming call or no dialing, the SIM card 2 maintains the standby state; if there is an incoming call or dialing, the user can choose to enter the call state, or hang up or select Send a short message to the calling party "in the phone, reply later", etc.; at this stage, the SIM card 1 is in a waiting state, waiting for the next handover;

Subsequent, the second RF1-baseband channel open phase:

When the switch switching module switches to the RF1-baseband channel for the second time, the SIM card 1 again occupies the baseband processing module, and the baseband processing module continues to process the call data of the SIM card 1;

The second RF2-baseband path open phase:

Similarly, the baseband processing module continues to process the SIM when the second RF2-baseband channel is turned on. Card 2 related communication data, etc.

This is continuously cycled in sequence. Therefore, in different time periods, the calls of SIM card 1 and SIM card 2 can be processed in a timely and complete manner, thereby realizing dual card dual communication.

Since the switch control module drives the switch switching module to continuously switch between the two paths of RF1-baseband and RF2-baseband, this avoids the radio frequency exclusive radio-baseband interface of the card when one card is called, resulting in another The problem that the card cannot be handled by the call occurs, thereby realizing the two-way radio frequency plus one baseband, achieving the purpose of dual-card dual-standby dual-pass.

In this embodiment, by using a set of baseband plus two sets of radio frequency and baseband-radio frequency interface sharing platform, by adding a switch switching module on the radio frequency-baseband interface, the two independent radio frequency modules are respectively recycled and released for baseband processing. The module avoids the monolithic RF-baseband interface (ie, exclusive baseband), thus realizing the dual-card dual-standby dual-pass of the mobile phone, which not only improves the utilization of the baseband resources, but also improves the user experience and the practicability of the dual-card mobile phone.
