Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Below in conjunction with accompanying drawing specific embodiment of the present invention is done detailed elaboration.
As shown in Figure 2; The present invention provides a kind of band NFC (Near Filed Communication; Near-field communication) mobile phone 20 of function comprises processor 201, SIM (Subscriber Identity Module User Recognition) module 202, NFC module 203, NFC antenna 204, transfer MCU 205 and the module (do not indicate) indispensable like mobile phones such as display screens.
In the present embodiment, NFC module 203 is connected in NFC antenna 204, is used to control the signal of NFC antenna 204 transmitting-receivings.NFC module 203 and NFC antenna 204 are operated in the 13.56MHz frequency range simultaneously.
Transfer MCU 205 is connected with processor 201, sim module 202 and 203 communications of NFC module respectively.Particularly; Transfer MCU 205 communication link are connected to NFC module 203; Be used to control NFC module 203 and realize near field communication (NFC) functions, and with the near-field communication storage that produces in the memory unit that sim module 202 or transfer MCU205 carry, have access to for processor 201.In this execution mode; Difference according to NFC module 203 self scheme; Transfer MCU205 can select different interfaces or agreement, for example adopts SPI (Serial Peripheral interface, row peripheral interface), UART (Universal Asynchronous Receiver Transmitter; UART Universal Asynchronous Receiver Transmitter), I2C (Inter-Integrated Circuit, twin wire universal serial bus) agreement.
Transfer MCU 205 is connected with sim module 202 and processor 201 communications, is used for that the data between sim module 202 and the processor 201 are carried out mutual transfer and transmits.In this execution mode, transfer MCU205 communicates through the ISO7816 agreement with sim module 202 and is connected.
In this execution mode, the mobile phone 20 of band NFC function can be supported telecommunications and two kinds of communication patterns of non-telecommunications.Particularly, the telecommunication path pattern is meant the communication of mobile phone, is mainly realized jointly by processor 201, transfer MCU 205 and sim module 202.The communication pattern of non-telecommunications is meant NFC communication, is realized by transfer MCU 205, NFC module 203 and NFC antenna 204.
Processor 201 is the processor of mobile phone circuit, is used to realize the conventional func of mobile phone, in addition, in this execution mode, has also increased and has controlled the function that transfer MCU 205 removes to have access to communication data.
As shown in Figure 3, in another embodiment, the mobile phone 30 of band NFC function can be with the be packaged into one of the NFC module among Fig. 2 305 with transfer MCU303.In this execution mode; NFC module 305 is packaged into NFC chip 306 with transfer MCU303; In other embodiments, also can transfer MCU 303 be encapsulated in the NFC module 305, or NFC module 305 is encapsulated among the transfer MCU303; So, its packaged type does not influence the effect of NFC module 303 and transfer MCU module 303.
Mobile phone 20,30 like the band NFC function of Fig. 2 and Fig. 3 designs processor 201, sim module 202, transfer MCU 205, NFC module 203 (or NFC chip 306) together, places on the mainboard of mobile phone 20,30 of band NFC function.And NFC antenna 204 can design (being the cell package form) on the circuit board of mobile phone, on the battery of mobile phone, on the bonnet of mobile phone (being the bonnet form), or is designed to other forms.During use,, just can realize telecommunications and non-telecommunications functions as long as it changes a NFC mobile phone 20,30, and not need to have bought the SIM of a special support SWP agreement again for the user who does not have NFC functional mobile phone 20,30.Transfer MCU is equivalent to only the data between handset processes device and the sim module carried out transparent transmission in this case.205 pairs of NFC modules 203 of transfer MCU are controlled; Realize mobile phone NFC function; Thereby function such as realize that the consumption of similar mobile phone gate inhibition, mobile phone is swiped the card; NFC functions of modules to mobile phone has no influence when changing different SIMs simultaneously, makes the availability of mobile phone, and multifunctionality and surcharge promote greatly.
To NFC mobile phone of the present invention, if being placed on the RF-SIM card of 2.4GHz on the sim module 202, the user uses, the user can realize the near field communication (NFC) function of 13.56MHz so, can realize the near field communication (NFC) function of 2.4G again.
Above-described embodiment of the present invention does not constitute the qualification to protection range of the present invention.Any modification of within spirit of the present invention and principle, being done, be equal to replacement and improvement etc., all should be included within the claim protection range of the present invention.
