Abstract
The invention is an improvement in efficient use of a radio communications channel, and for inhibiting transmission of an unwanted radio wave on a SCO communications link established between Bluetooth radio communications terminals as well as reducing power consumption. A sound signal that transmitted along a SCO communications link is detected. When the signal is absent, the communications link is once disconnected and, the communications link is connected again when a sound signal is detected. Instruction for disconnection and reconnection of a communications link may be done by a control signal coming from a call button provided on the communications terminals.
Claims9
A radio communications terminal that establishes a radio communications channel to a remote terminal for transmitting a signal by using time slots that have undergone time-division processing and transmits a sound signal via said radio communications channel, comprising:
- a radio communications part which establishes said radio communications channel and transmits a sound signal via said radio communications channel;
- and
- a control part which controls establishment of the radio communications channel by said radio communications part, and transmission of the sound signal via said radio communications channel, wherein
- after said radio communications channel is established, said control part controls said radio communications part to disconnect or reestablish said radio communications channel, based on a disconnection instruction signal or a reestablishment instruction signal.
A radio communications terminal that establishes a radio communications channel to a remote terminal for transmitting a signal and transmits a sound signal via said radio communications channel, comprising:
- a radio communications part which establishes said radio communications channel and transmits a sound signal via said radio communications channel;
- and
- a control part which controls establishment of the radio communications channel by said radio communications part, and transmission of the sound signal via said radio communications channel, wherein
- said control part controls said radio communications part to disconnect or reestablish said radio communications channel, on the basis of whether or not transmission of said sound signal meets a predetermined condition.
A radio communications method that establishes a radio communications channel between a radio communications terminal and a remote terminal such that said radio communications terminal transmits a sound signal to said remote terminal via said radio communications channel, comprising the steps of:
- A) establishing said radio communications channel and transmitting said sound signal via said radio communications channel;
- B) determining whether or not transmission of said sound signal meets a predetermined condition;
- C) determining whether said radio communications channel should be disconnected or reestablished, on the basis of a determination made in Step B;
- and
- D) disconnecting said radio communications channel when Step C determines disconnection, and reestablishing said radio communications channel when Step C determines reestablishment.
