Embodiment of the method one
According to embodiments of the invention, the implementation method of a kind of eNFC is provided, the method can be applicable to support the portable terminal of a plurality of SIM card.Fig. 3 is the flow chart according to the implementation method of the eNFC of the inventive method embodiment one, and as shown in Figure 3, the method comprises that following step S302 is to step S308:
Step S302 selects to need to carry out the SIM card of swiping the card and operating from a plurality of SIM card.
Step S304, the mode card of the eNFC chip that unlatching is connected with the SIM card of selecting.
Step S306 is connected the NFC antenna with the eNFC chip, so that SIM card and reader are carried out the operation of swiping the card.
Step S308, if swipe the card operation failure, then portable terminal reselects this failed SIM card or selects other SIM card to carry out the operation of swiping the card, and preferably, can close the mode card of the corresponding eNFC chip of SIM card of the failure of swiping the card.
Wherein, terminal reselects other SIM card and carries out the operation of swiping the card and comprise: select one by one needs to carry out the SIM card of swiping the card and operating from other SIM card; Open the mode card of the eNFC chip that is connected with current selected SIM card; The NFC antenna is connected with the corresponding eNFC chip of current selected SIM card, so that this SIM card and reader are carried out the operation of swiping the card, until the swiping the card of a SIM card of setting up communication link with reader operate successfully or swiping the card of all SIM card operates all unsuccessfully.And the failure in the situation that all SIM card are all swiped the card is if portable terminal away from reader, then can reconnect the NFC antenna to the NFC chip of acquiescence.
Need to prove, can from a plurality of SIM card, select a SIM card acquiescence to carry out the operation of swiping the card, that is, portable terminal can be set adopt a SIM card acquiescence to carry out the operation of swiping the card, and the mode card of the eNFC chip that is connected with this SIM card also is unlocked.Other SIM card can't be carried out the operation of swiping the card, and when this card was swiped the card failure, portable terminal still can select this SIM card to swipe the card.
By this embodiment, can realize under mode card, use according to the eNFC that a plurality of SIM card interfaces are set on the eNFC chip, solved that portable terminal can not use the eNFC application problem of a plurality of SIM card simultaneously in the correlation technique, and then improved user's experience.
, take the double SIM card portable terminal as example the implementation procedure of the embodiment of the invention is described in detail below in conjunction with accompanying drawing.
Example 1
Fig. 4 is that portable terminal according to the inventive method embodiment one is during as mode card, the flow chart that software is processed, as shown in Figure 4, when portable terminal uses mode card to communicate with reader, in the portable terminal main control module, comprise that following step S402 is to step S418:
Step S402, the mode card of unlatching N1.
Step S404, the portable terminal main control module connects the NFC antenna by control interface control NFC duplexer with N1,, be communicated with N1 and NFC antenna that is.
Step S406 judges by N1 whether its SIM card that connects is chosen by reader, namely, judge that whether portable terminal can begin to swipe the card near reader, if judged result is yes, then proceeds to step S408, if the determination result is NO, process ends then.
Step S408 judges whether reader and SIM card 1 connect, if connect, then proceed to step S410, otherwise, proceed to step S412.
Step S410, the transaction of swiping the card is finished and is swiped the card, process ends.
Step S412 closes the mode card of N1, opens the mode card of N2.
Step S414, the portable terminal main control module connects the NFC antenna by control interface control NFC duplexer with N2.
Step S416 judges by the NFC chip whether the SIM card that N2 connects is chosen by reader, if choose, then proceeds to step S418, otherwise, think in the current SIM card without the application that adapts with reader, process ends.
Need to prove, this embodiment describes as an example of two eNFC chips example, also can comprise a plurality of eNFC chips, in this case, if it is selected that the SIM card that N2 connects among the step S416 does not have, then judge whether all end of polling(EOP)s of all NFC chips, if, then think the corresponding application of function that SIM card in the current mobile terminal does not require with reader, process ends; If not, re-use selection and the poll of finishing other NFC chip with step S412 to the similar method of step S416.
By this embodiment, the eNFC that uses simultaneously a plurality of SIM card in the same terminal is used becomes possibility, has made things convenient for the consumer.
Example 2
Usually, portable terminal may make a SIM card " permanent online ", that is, the user does not need manual intervention, and portable terminal is in the card state always, as long as just can realize the action of swiping the card near reader.Such as, N1 " permanent online ", that is, and mode card one direct-open of N1, and the NFC switch is communicated with N1 and NFC antenna simultaneously.
Fig. 5 is the flow chart that software is processed during as mode card and " permanent online " according to the portable terminal of the inventive method embodiment one, and as shown in Figure 5, the method comprises that following step S502 is to step S520:
Step S502 judges whether that portable terminal is near the reader action of swiping the card, namely, portable terminal is waited for and is judged whether near reader, because therefore the NFC antenna is connected on the N1, by the NFC duplexer, portable terminal is in case near reader, and N1 just can sense the read-write of reader.In the situation of the signal that detects reader, proceed to step S504, otherwise, continue execution in step S502.
Step S504, N1 judge whether reader has chosen SIM card 1, and carry out corresponding read-write operation, that is, whether reader has been set up with SIM card 1 is connected, and if so, then reports main control module, proceeds to step S506; If not, proceed to step S508.
Step S506, the transaction of swiping the card is finished and is swiped the card, process ends.
Step S508, the mode card of unlatching N2.
Step S510, control NFC duplexer is connected N2 with the NFC antenna.
Step S512, N2 judge whether reader has chosen SIM card 2, and carry out corresponding read-write operation,, judge whether reader and SIM card 2 connect, and if so, then report main control module, proceed to step S514 that is; If not, proceed to step S516.
Step S514, the transaction of swiping the card is finished and is swiped the card, process ends.
Step S516, whether main control module judges portable terminal away from reader by N1 and N2, if this moment, duplexer connected N1, then main control module is judged by N1; If duplexer connects N2, then main control module is judged by N2; If judged result is yes, then proceed to step S518, if the determination result is NO, then continue execution in step S516.
Step S518 opens the mode card of N1.
Step S520, control NFC duplexer connects N1 and NFC antenna.
By this embodiment, all can't finish the operation of swiping the card if portable terminal has traveled through all SIM card, and this portable terminal reopens the mode card of N1 after away from reader, that is to say, the SIM card that acquiescence N1 is corresponding is carried out the operation of swiping the card.
