Portable terminal apparatus, its control method, and program
View Patent ↗Disclosed is a portable terminal apparatus in which there is provided a storage unit in which the setting of automatic holding of a right to talk is stored and held. In response to detection of depression of a right to talk acquisition key prepared in advance, a CPU references the setting of the automatic holding of a right to talk stored in the storage unit and, if the automatic holding of a right to talk is effective, comes into a waiting state of the right to talk acquisition, tries to acquire the right to talk at a predetermined interval, and repeats this operation until the right to talk is successfully acquired. Once acquired, the right to talk is held until a right to talk automatic holding time stored in the storage unit elapses.
1. A portable terminal apparatus equipped with a PTT (Push to Talk) communication function, said apparatus comprising:
a storage unit that stores and holds setting of whether or not automatic holding of a right to talk is made effective; and
a CPU that references the setting of the automatic holding of a right to talk stored in said storage unit in response to detection of depression of a right to talk acquisition key on an input unit, and, if the automatic holding of a right to talk is set effective, performs control to repeat an operation of acquiring a right to talk, at a predefined predetermined time interval, in a right to talk acquisition wait mode, until the right to talk is successfully acquired.
2. The portable terminal apparatus according to claim 1 , wherein said storage unit stores and holds a right to talk automatic holding time; and
said CPU performs control to hold the acquired right to talk until the right to talk automatic holding time stored in said storage unit elapses after the right to talk is acquired.
3. The portable terminal apparatus according to claim 1 , wherein said CPU performs control to hold the acquired right to talk until a predefined time elapses with a talking voice level remaining below a predetermined threshold.
4. The portable terminal apparatus according to claim 1 , wherein said CPU performs control to hold the acquired right to talk until the depression of said right to talk acquisition key is detected again.
5. The portable terminal apparatus according to claim 1 , wherein the predetermined time interval, at which said CPU repeats the operation of acquiring a right to talk, is able to be variably set.
6. The portable terminal apparatus according to claim 1 , wherein said CPU performs control so that, if the automatic holding of a right to talk is set ineffective and if the right to talk is acquired successfully, the acquired right to talk is held while the right to talk acquisition key is pressed.
7. The portable terminal apparatus according to claim 1 , wherein said CPU performs speech recognition in response to an input speech signal from a speech input unit; and
said CPU performs the operation of acquiring a right to talk, based, not on the detection of depression of said right to talk acquisition key on said input unit, but on a result of the speech recognition.
8. A control method of a portable terminal apparatus equipped with a PTT(Push to Talk) communication function, wherein a setting of whether or not automatic holding of a right to talk is made effective is stored and held in a storage unit of said apparatus, said method comprising:
referencing the setting of the automatic holding of a right to talk, stored in said storage unit, in response to detection of depression of a right to talk acquisition key; and
performing, if the automatic holding of a right to talk is set effective, control to repeat an operation of acquiring a right to talk, at a predefined predetermined time interval, in a right to talk acquisition wait mode, until the right to talk is successfully acquired.
9. The control method of a portable terminal apparatus according to claim 8 , wherein a right to talk automatic holding time is stored and held in said storage unit,
said control method further comprising
holding the acquired right to talk, until the right to talk automatic holding time stored in said storage unit elapses after the right to talk is acquired.
10. A computer program causing a computer, which constitutes a portable terminal apparatus that includes a storage unit, in which a setting of whether or not automatic holding of a right to talk is made effective is stored and held, and that has a PTT(Push to Talk) communication function, to execute a right to talk automatic acquisition processing which
references the setting of automatic holding of a right to talk, stored in said storage unit, in response to detection of depression of a right to talk acquisition key on an input unit; and
if the automatic holding of a right to talk is set effective, performs control to repeat an operation of acquiring a right to talk, at a predefined predetermined time interval, in a right to talk acquisition wait mode, until the right to talk is successfully acquired.
11. The program according to claim 10 , wherein said storage unit stores and holds a right to talk automatic holding time;
said program further causing said computer to execute a right to talk automatic holding processing which holds the acquired right to talk until the right to talk automatic holding time, stored in said storage unit, elapses after the right to talk is acquired.
