Handsfree device and mobile phone handset
First Claim
1. A handsfree device, comprising:
- a communication circuit for simultaneously maintaining a plurality of connections with a mobile phone handset, through a plurality of wireless channels;
ring-tone sound output controlling means for making a speaker output a sound depending on a received ring-tone signal, after receiving the ring-tone signal from the mobile phone handset connected with the communication circuit;
reception controlling means for receiving, by means of the communication circuit, information on the mobile phone handset transmitted from the mobile phone handset;
transmission controlling means for transmitting selection information to the mobile phone handset by means of the communication circuit, according to a state of the connections through the channels and the information on the mobile phone handset received by the reception controlling means, for selecting the ring-tone signal to be transmitted from the mobile phone handset; and
range information transmission controlling means for transmitting range information to the mobile phone handset by means of the communication circuit, the range information being information on a restriction to a frequency range used by the ring-tone signal to be received by the ring-tone sound output controlling means, the range information being changed depending on the state of the connections through the channels.

Abstract
By executing a ring-tone determination program and so on, a handsfree device transmits range information to a mobile phone handset connected with the handsfree device. When the handsfree device receives information of frequency ranges used by ring-tone signals in the handset, it makes a determination according to the received information. If the received information indicates that the handset is compatible with the range information, it transmits a signal for directing not to restrict a frequency range. If the received information indicates that the handset is not compatible with the range information, it transmits either of a signal for directing to restrict a frequency range or a denial signal denying the reception of ring-tone sound, depending on a setting in the handsfree device.

11. A mobile phone handset, comprising:
-
a storage medium for storing a ring-tone dataset; a handsfree communication circuit for maintaining a plurality of connections through a plurality of wireless channels at a time with a handsfree device, which receives a ring-tone signal from the mobile phone handset and outputs a ring-tone sound depending on the ring-tone signal to the speaker, when the mobile phone handset receives a phone call; range information reception controlling means for receiving, by means of the handsfree communication device, a range information transmitted from the handsfree device, the range information being information on a restriction to a frequency range used by the ring-tone signal to be received by the handsfree device and the range information being changed depending on the state of the connections through the channels; ring-tone compatible/incompatible transmission control means for transmitting presence/absence information to the handsfree device by means of the handsfree communication circuit, according to comparison between the range information which the range information reception controlling means received and a frequency range used by the ring-tone dataset stored by the storage medium, the presence/absence information being information on the presence or absence of the ring-tone signal transmittable to the handsfree device; ring-tone acceptance/denial reception control means for receiving, by means of the handsfree communication circuit, acceptance/denial information transmitted by the handsfree device, as a response to the presence/absence information transmitted by the ring-tone compatible/incompatible transmission control means, the acceptance/denial information being information on whether the handsfree device receives the ring-tone signal when the mobile phone handset receives a phone call; and ring-tone transmission controlling means for transmitting, by means of the handsfree communication circuit, the ring-tone signal depending on the ring-tone dataset stored by the storage medium to the handsfree device, based on that the acceptance/denial information received by the ring-tone acceptance/denial reception control means indicates that the handsfree device receives the ring-tone signal when the mobile phone handset receives a phone call. - View Dependent Claims (12)
