Abstract

A mobile electronic device that transmits and receives data with respect to an external device by wireless communication receives electric power from the external device by wireless and supplies electric power to respective portions of the mobile electronic device. The mobile electronic device includes a transmission/reception unit configured to transmit and receive data with respect to the external device and a plurality of signal processor units configured to subject data transmitted and received by the transmission/reception unit to signal processes according to different communication protocols. The mobile electronic device determines a communication protocol based on data received by the transmission/reception unit, selects one of the plurality of signal processor units based on the determination result, and performs a control operation to cause the transmission/reception unit to transmit and receive data by use of the selected signal processor unit.

Claims

1. A mobile electronic device that transmits and receives data with respect to an external device by wireless communication, comprising:

a power source unit configured to receive electric power from the external device by wireless and supply electric power to respective portions of the mobile electronic device,

a transmission/reception unit configured to transmit and receive data with respect to the external device,

a plurality of signal processor units configured to signal process according to different communication protocols to the data transmitted and received by the transmission/reception unit,

a determination unit configured to determine a communication protocol based on data received by the transmission/reception unit,

a selection unit configured to select one of the plurality of signal processor units based on a determination result of the determination unit, and

a control unit configured to performs a control operation to cause the transmission/reception unit to transmit and receive data by use of the signal processor unit selected by the selection unit.

2. The mobile electronic device according to claim 1, which further comprises a first storage unit configured to store protocol information indicating a communication protocol determined by the determination unit and in which the selection unit determines one of the signal processor units to be selected with reference to protocol information stored in the first storage unit.

3. The mobile electronic device according to claim 2, wherein the first storage unit limits a process of rewriting protocol information while receiving electric power from the power source unit.

4. The mobile electronic device according to claim 3, wherein the first storage unit releases the limitation of the process of rewriting protocol information when it is detected that the mobile electronic device is set in a halt state by receiving one of a halt command and release command.

5. The mobile electronic device according to claim 1, which further comprises a second storage unit configured to store a plurality of applications and management information of the respective applications and in which the management information stored in the second storage unit includes information that limits an execution process of the application for each communication protocol.

6. The mobile electronic device according to claim 1, wherein the control unit allocates channels to the respective communication protocols and performs a process for each channel.

7. A control method of a mobile electronic device including a plurality of signal processor units that perform signal processes according to different communication protocols in which data is transmitted and received with respect to an external device by wireless communication, comprising:

determining a communication protocol based on data received from the external device,

selecting one of the plurality of signal processor units based on a determination result, and

performing a control operation to transmit and receive data with respect to the external device by use of the selected signal processor unit.
