Abstract

A communication terminal includes a first communication unit which has a power supply function by electromagnetic induction and writes or reads information in an active or passive mode, and a second communication unit having a communication capability higher than that of the first communication unit. A mode in which the first communication unit is functioning, the active mode or the passive mode, is determined. Communication via the second communication unit is controlled based on the determination result.

Claims

1-9. -9. (canceled)

10. A communication terminal, comprising:

a first communication unit capable of communicating by a first communication method having a first mode and a second mode, wherein communication in the first mode is for writing processing in other apparatus in the second mode or reading processing from other apparatus in the second mode, and communication in the second mode is for writing processing or reading processing that is performed by other apparatus in the second mode;

a second communication unit capable of communicating by a second communication method of which a communication speed is higher than that of the first communication method, as a first role or a second role, wherein the second communication unit communicates as the first role for a control of communication with other apparatus communicating as the second role, and the second communication unit communicates as the second role according to a control by other apparatus communicating as the first role;

a controller that connects to the first communication unit via a signal line and controls the communication terminal; and

a determination unit that, in a case where the first communication unit wirelessly connects to a communication partner terminal, determines whether the second communication unit communicates as the first role or the second role based on an output result output from the first communication unit to the controller via the signal line,

wherein the second communication unit communicates with the partner terminal as the first role or the second role which is determined by the determination unit.

11. The communication terminal according to claim 10, wherein the determination unit determines whether the first communication unit determines the role of the second communication unit based on the output result indicating that the first communication unit communicates in the first mode or the second mode.

12. The communication terminal according to claim 10, wherein the determination unit determines that the second communication communicates as the first role in a case where the output result indicates first information and the determination unit determines that the second communication communicates as the second role in a case where the output result indicates second information different from the first information.

13. The communication terminal according to claim 10, wherein the first communication unit performs communication using Radio Frequency Identification.

14. The communication terminal according to claim 10, wherein the second communication unit performs communication using Universal Serial Bus On The Go.

15. The communication terminal, according to claim 10, wherein, when the second communication unit communicate as the first role, the communication terminal functions as a host to other apparatus communicating as the second role.

16. The communication terminal, according to claim 15, wherein, when the second communication unit communicates as the second role, the communication terminal functions as a device hosted by other apparatus communicating as the first role.

17. The communication terminal, according to claim 12, wherein a signal level of the output result indicating the first information differs from a signal level of the output result indicating the second information.

18. The communication terminal according to claim 10 further comprising a activation unit that activates the second communication unit when the first communication unit communicates with the partner terminal.

19. A control method in a communication terminal, comprising:

communicating by a first communication unit capable of communicating by a first communication method having a first mode and a second mode, wherein communication in the first mode is for writing processing in other apparatus in the second mode or reading processing from other apparatus in the second mode, and communication in the second mode is for writing processing or reading processing that is performed by other apparatus in the second mode;

communicating by a second communication unit capable of communicating by a second communication method of which a communication speed is higher than that of the first communication method, as a first role or a second role, wherein the second communication unit communicates as the first role for a control of communication with an other communication apparatus communicating as the second role, and the second communication unit communicates as the second role according to a control by other communication apparatus communicating as the first role;

controlling by a controller that connects to the first communication unit via a signal line and controls the communication terminal; and

determining, in a case where the first communication unit wirelessly connects to a communication partner terminal, whether the second communication unit communicates as the first role or the second role based on an output result output from the first communication unit to the controller via the signal line,

wherein the second communication unit communicates with the partner terminal as the first role or the second role which is determined in the determining.

20. A non-transitory computer readable storage medium storing a computer program that, when executed, causes a computer to perform a method, the computer being incorporated in a communication apparatus, the method comprising:

communicating by a first communication unit capable of communicating by a first communication method having a first mode and a second mode, wherein communication in the first mode is for writing processing in other apparatus in the second mode or reading processing from other apparatus in the second mode, and communication in the second mode is for writing processing or reading processing that is performed by other apparatus in the second mode;

communicating by a second communication unit capable of communicating by a second communication method of which a communication speed is higher than that of the first communication method, as a first role or a second role, wherein the second communication unit communicates as the first role for a control of communication with other communication apparatus communicating as the second role, and the second communication unit communicates as the second role according to a control by other communication apparatus communicating as the first role;

controlling by a controller that connects to the first communication unit via a signal line and controls the communication terminal; and

determining, in a case where the first communication unit wirelessly connects to a communication partner terminal, whether the second communication unit communicates as the first role or the second role based on an output result output from the first communication unit to the controller via the signal line,

wherein the second communication unit communicates with the partner terminal as the first role or the second role which is determined in the determining.
