Number, then SIM 2 maintains holding state；If having incoming call or having dialing, then can select to enter and lead to
Speech phase, or hang up or select short-message sending " the most in the phone, to return after a while to MPTY
Multiple " etc..This stage SIM 1 is waited for, and waits and switches arrival next time.
Follow-up, RF1-Baseband Channel opening stage for the second time:
When switch handover module second time switch to RF1-Baseband Channel open time, SIM 1 accounts for again
With baseband processing module, baseband processing module may proceed to process the communicating data of SIM 1；
RF2-baseband paths opening stage for the second time:
Similarly, when second time RF2-Baseband Channel is opened, baseband processing module may proceed to process SI
The associated communication data etc. of M card 2.
The most constantly cyclic switching goes down successively.So in the different time periods, SIM 1 and SIM
The call of 2 can obtain timely, complete process, thus realizes double card bilateral.
