[0027] figure 1 It is a block diagram of the mobile terminal system in the first embodiment of the present invention.

[0028] The terminal body of the mobile terminal is provided with a SIM card slot 100, the SIM card 110 can be inserted into the SIM card slot 100 to realize electrical connection with the relevant communication function modules in the terminal body, and the small antenna unit 120 is attached to the outer surface of the mobile terminal , and realize electrical connection with the SIM card 110 .

[0029] The present invention mainly designs each functional circuit in the SIM card 110. The SIM card 110 is provided with a system bus 115, a main control circuit 111, a short-range wireless communication functional circuit 117, a radio frequency functional circuit 112, a Bluetooth communication circuit 113 and an interface The circuits 114 are all mounted on the system bus 115, and the communication and interaction between the circuits are realized through the syst...

[0035] Such as figure 2 As shown, this embodiment is based on the expansion of the first embodiment, and mainly expands the short-distance wireless communication function circuit 117. In this embodiment, a short-distance card reader circuit 1171 and a short-distance card circuit 1172 are provided at the same time. Of course, only the short-distance card reader circuit 1171 or only the short-distance card circuit 1172 may be provided.

[0036] When performing the short-distance card reader function, the main control circuit 111 controls the short-distance card reader circuit 1171 to realize short-distance wireless communication read and write control operations through the external coupling antenna, which is arranged in the small antenna unit 120 .

[0037]When operating the proximity card, the proximity card circuit 1172 realizes the radio frequency communication of the proximity card through an external coupling antenna, and the coupling antenna is arranged in the small ante...

[0041] Such as image 3 As shown, this embodiment is based on the second embodiment, and a proximity distance control circuit 119 is connected to the system bus 115 . The short-distance control circuit 119 is mainly used for distance control of short-distance wireless communication. When implemented, the short-distance control circuit 119 induces a low-frequency magnetic signal through an external low-frequency magnetic field antenna, and performs distance control according to the low-frequency magnetic signal. When the distance control condition is satisfied, the short-distance card reader circuit 1171 and / or the short-distance card circuit 1172 work.

[0042] In this embodiment, the interface circuit 114 can also be expanded, and the interface circuit 114 includes: an interface controller and an interface. The number of interfaces may be multiple, and the interfaces are connected to the system bus 115 through an interface controller.

Abstract

The invention discloses a SIM card and a mobile terminal. The internal part of the SIM card realize communication interaction through a system bus through separating a near-field wireless communication coupling antenna from a near-field wireless communication functional circuit and a 2.4GHz ISM (Industry Science Medicine) band communication functional circuit in the SIM card in the physical spaceand corresponding setting an interface circuit in the SIM card, thereby increasing a near-field wireless communication function, improving the effect of radio frequency communication, and reserving aspace for function expansion of the SIM card.

Description

technical field [0001] The invention relates to the field of mobile communication technology and radio frequency communication technology, in particular to a SIM card and a mobile terminal. Background technique [0002] SIM cards are generally used in current mobile communication terminals, and the SIM generally has a subscriber identification module for uniquely identifying the identity of the terminal user. In the process of using the mobile terminal for mobile communication, it can communicate as a user. Of course, in some special cases, such as an emergency call, the mobile terminal can also perform emergency communication without using a SIM card. The SIM card is generally a microcircuit card, and a chip is arranged in the card, and contents such as user identification information and encryption keys are stored on it. [0003] With the development of technology, some mobile terminals with radio frequency communication function have appeared on the market, and radio fre...
