Problems solved by technology
[0003] Currently, in a mobile terminal with two Subscriber Identification Module (SIM, Subscriber Identification Module) cards, an NFC controller (NFCC, Near Field Communication Controller) will be fixedly connected to one of the two SIM card slots, resulting in NFCC can only communicate with the SIM card in the fixed card slot
On the one hand, the two SIM cards cannot be used effectively, only the SIM card in the fixed card slot can use the NFC function, while the SIM card in the other card slot does not have the NFC function
On the other hand, when the fixed card slot fails, the mobile terminal cannot use the NFC function
Therefore, the mobile terminal is poor in intelligence. For example, when the user wants the SIM card in the non-fixed card slot to realize the NFC function, he needs to manually change the position of the SIM card, which virtually reduces the user experience and brings benefits to the user.

The embodiment of the present invention discloses a near-field communication NFC device. The NFC device includes: an NFC controller, a first switch, and a second switch; the NFC controller is respectively connected to the first switch and the second switch; wherein, the NFC controller, Used to obtain SIM card selection parameters; generate NFC channel switching signals and power supply channel switching signals according to the SIM card selection parameters; send the NFC channel switching signals to the first switch, and send the power supply channel switching signals to the second switch; the first The switch is used to respond to the NFC channel switching signal, turn on the NFC channel of the first SIM card, and disconnect the NFC channel of the second SIM card; the second switch is used to respond to the power supply channel switching signal, and switch the first SIM card The power supply path is turned on. The embodiment of the invention also discloses an NFC switching method and device.
Description
technical field [0001] The present invention relates to near field communication (NFC, Near Field Communication) technology in the field of wireless communication, and in particular to an NFC device, an NFC switching method and an NFC control device. Background technique [0002] In recent years, NFC technology has attracted more and more people's attention. NFC technology combines non-contact sensing and wireless connection technology. Mobile communication devices can identify and exchange data with compatible devices within a short distance through NFC, which can be used for people's daily life. Bring convenience. [0003] Currently, in a mobile terminal with two Subscriber Identification Module (SIM, Subscriber Identification Module) cards, an NFC controller (NFCC, Near Field Communication Controller) will be fixedly connected to one of the two SIM card slots, resulting in NFCC can only communicate with the SIM card in the fixed card slot. On the one hand, the two SIM c...
