Abstract
A mobile device includes an electronic card slot to be connected to an electronic card, and a baseband module. The baseband module includes a baseband unit, a switching unit, and a control unit. When it is determined by the control unit that the electronic card conforms with a subscriber identification communication protocol, the baseband unit and the electronic card slot are electrically interconnected via the switching unit such that the baseband unit is able to communicate with the electronic card that is connected to the electronic card slot. When the determination is otherwise, the baseband unit and the electronic card slot are electrically interconnected via the control unit.
Claims20
A mobile device, comprising:
- a first electronic card slot to be connected to a first electronic card;
- and
- a baseband module including
- a first baseband unit that includes an application processor and a baseband processor,
- a switching unit coupled to said first baseband unit and said first electronic card slot, and
- a control unit coupled to said first baseband unit, said first electronic card slot, and said switching unit;
- wherein said control unit of said baseband module is configured to operate in a first transmission mode, in which said first baseband unit and said first electronic card slot are electrically interconnected via said switching unit such that said first baseband unit is able to communicate with the first electronic card that is connected to said first electronic card slot, when it is determined by said control unit that the first electronic card conforms with a subscriber identification communication protocol;
- wherein said control unit of said baseband module is further configured to operate in a second transmission mode, in which said first baseband unit and said first electronic card slot are electrically interconnected via said control unit, when it is determined by said control unit that the first electronic card does not conform with the subscriber identification communication protocol;
- wherein the baseband module is an input/output device that supports ISO 7816/Universal Asynchronous Receiver/Transmitter (UART) specification;
- and
- wherein the first transmission mode enables operations related to mobile telephony service to be performed, and the second transmission mode enables operations concerning electronic commerce to be performed.
A baseband module for communicating with a first electronic card connected to a first electronic card slot, said baseband module comprising:
- a first baseband unit that includes an application processor and a baseband processor;
- a switching unit coupled to said first baseband unit and to be coupled to the first electronic card slot;
- and
- a control unit coupled to said first baseband unit and said switching unit, and to be coupled to the first electronic card slot;
- wherein said control unit is configured to operate in a first transmission mode, in which said first baseband unit and the first electronic card slot are electrically interconnected via said switching unit such that said first baseband unit is able to communicate with the first electronic card that is connected to the first electronic card slot, when it is determined by said control unit that the first electronic card conforms with a subscriber identification communication protocol;
- wherein said control unit is further configured to operate in a second transmission mode, in which said first baseband unit and the first electronic card slot are electrically interconnected via said control unit such that said first baseband unit is able to communicate with the first electronic card that is connected to the first electronic card slot, when it is determined by said control unit that the first electronic card does not conform with the subscriber identification communication protocol;
- wherein said baseband module is an input/output device that supports ISO 7816/Universal Asynchronous Receiver/Transmitter (UART) specification;
- wherein the first transmission mode enables operations related to mobile telephony service to be performed;
- and the second transmission mode enables operations concerning electronic commerce to be performed.
A method for signal transmission to be implemented by a baseband module of a mobile device, the mobile device including an electronic card slot coupled to the baseband module and to be connected to an electronic card, and a storage unit coupled to the baseband module, the baseband module including a baseband unit, a switching unit and a control unit, said method comprising the following steps of:
- configuring the baseband module to operate in a first transmission mode, in which the baseband unit and the electronic card slot are electrically interconnected via the switching unit such that the baseband unit is able to communicate with the electronic card that is connected to the electronic card slot, when it is determined by the control unit that the electronic card conforms with a subscriber identification communication protocol;
- and
- configuring the baseband module to operate in a second transmission mode, in which the baseband unit and the electronic card slot are electrically interconnected via the control unit, when it is determined by the control unit that the electronic card does not conform with the subscriber identification communication protocol;
- wherein the baseband module is an input/output device that supports ISO 7816/Universal Asynchronous Receiver/Transmitter (UART) specification;
- wherein the first transmission mode enables operations related to mobile telephony service to be performed, and the second transmission mode enables operations concerning electronic commerce to be performed.
