Abstract

A mobile communication device for communicating a radio communication device associated with a radio transmitter. The mobile communication device includes a short-range radio communication unit configured to transmit a requirement signal for short-range radio communication connection to the radio communication device, and configured to receive a signal from the radio communication device for short-range radio communication connection. The mobile communication device includes a memory configured to store a data, the data needed to transmit the requirement signal. The mobile communication device includes a controller coupled to the short-range radio communication unit and the memory, and configured to wait for the signal from the radio communication device if the short-range radio communication unit tries to transmit the requirement signal to the radio communication device, and if a connection between the mobile communication device and the radio communication device has failed.

2. The mobile communication device according to claim 1, wherein:

the memory stores information indicating whether or not the radio communication device is capable of transmitting the second request signal to the mobile communication device; and

the controller controls the mobile communication device to switch from the client mode to the server mode to wait for the second request signal from the radio communication device, if the controller determines the radio communication device is capable of transmitting the second request signal to the mobile communication device based on the information.

3. The mobile communication device according to claim 2, wherein the controller is configured to control the mobile communication device to wait in the server mode for the second request signal from the radio communication device for a predetermined time and then to stop waiting for the second request signal.

4. The mobile communication device according to claim 1, wherein the controller is configured to control the mobile communication device to wait in the server mode for the second request signal from the radio communication device for a predetermined time and then to stop waiting for the second request signal.

5. A mobile communication device for communicating with a radio communication device, the mobile communication device comprising:

a short-range radio communication unit configured to transmit a first request signal for short-range radio communication connection to the radio communication device in a client mode, and configured to receive a second request signal for short-range radio communication connection from the radio communication device in a server mode, the second request signal being necessary for establishing a short range radio communication connection;

a memory configured to store music data and setting information, the setting information indicating an output unit to which the music data is to be transmitted;

a reproduction unit configured to reproduce the music data; and

a controller configured (i) to control the mobile communication device to, in the client mode, try to transmit the first request signal to the radio communication device if the reproduction unit is required to reproduce the music data and if the output unit is the radio communication device and to wait in the client mode for establishment of a short-range radio communication connection to the radio communication device in response to the first request signal, (ii) to control the mobile communication device to switch from the client mode to the server mode to wait for the second request signal from the radio communication device in response to a failure to establish a short-range radio communication connection between the mobile communication device and the radio communication device while the mobile communication device is in the client mode, and (iii) to control the mobile communication device such that the mobile communication device does not switch from the client mode to the server mode if a short-range radio communication connection between the mobile communication device and the radio communication device is established when the mobile communication device is in the client mode.

6. The mobile communication device according to claim 5, further comprising:

a speaker;
