Speech communication system and talker right reservation method

A portable terminal apparatus comprising:

• a transmission control unit which transmits speech to another terminal when a talker right is given by a server device which manages the talker right specifying a terminal which transmits speech when speech communication is performed between portable terminals;
• and
• a registration request notification unit which transmits, to the server device in response to predetermined external operation, a registration request notification for requesting registration of a reservation for the talker right;
• a first notification unit which exteriorly notifies that a reservation for the talker right has been registered by another terminal, when a self terminal is holding the talker right, in response to a reservation addition notification indicating that the reservation has been registered;
• a second notification unit which exteriorly notifies acquisition of the talker right for a predetermined period of time when the talker right is acquired by registration of a reservation for the talker right;
• and
• a talker right releasing unit which releases the acquired talker right when predetermined operation is not executed before notification by said second notification unit is complete,
• wherein at least one of said first notification unit and said second notification unit comprises one of a vibration generating unit which vibrates the self terminal, a light-emitting unit which emits light, a sounding unit which generates preset notification sound, a text display unit which displays text information indicating a notification content, and an image display unit which displays image information indicating the notification content.

A talker right reservation method comprising:

• the step of causing a portable terminal to transmit a registration request notification for requesting registration of a reservation for a talker right, to the server device which manages the talker right specifying a terminal which transmits speech when speech communication is performed between a plurality of portable terminals in response to predetermined external operation;
• the step of causing the server device to register a reservation for the talker right in a management table which stores management information containing a reservation status of the talker right, in accordance with a registration request notification from the portable terminal;
• the step of causing the portable terminal to exteriorly notify, by using a first notification unit, that a reservation has been registered, when the talker right is held by a self terminal, in response to a reservation addition notification indicating that the reservation for the talker right made by another terminal has been registered;
• the step of causing the portable terminal to exteriorly notify acquisition of the talker right for a predetermined period of time by using a second notification unit when the talker right is acquired by the registration of the reservation for the talker right;
• and
• the step of releasing the acquired talker right when predetermined operation is not executed before notification by the second notification unit is complete,
• wherein at least one of the first notification unit and the second notification unit comprises one of a vibration generating unit which vibrates the self terminal, a light-emitting unit which emits light, a sounding unit which generates preset notification sound, a text display unit which displays text information indicating a notification content, and an image display unit which displays image information indicating the notification content.

A recording medium which records a program for causing a computer to execute:

• the step of giving one of portable terminals a talker right for specifying a terminal which transmits speech when speech communication is performed between the portable terminals;
• the step of registering a reservation for the talker right in a management table storing management information containing a reservation status of the talker right in accordance with a notification transmitted from a portable terminal to which the talker right is not given;
• the step of causing the portable terminal to exteriorly notify, by using a first notification unit, that a reservation has been registered, when the talker right is held by a self terminal, in response to a reservation addition notification indicating that the reservation for the talker right made by another terminal has been registered;
• the step of causing the portable terminal to exteriorly notify acquisition of the talker right for a predetermined period of time by using a second notification unit when the talker right is acquired by the registration of the reservation for the talker right;
• and
• the step of releasing the acquired talker right when predetermined operation is not executed before notification by the second notification unit is complete,
• wherein at least one of the first notification unit and the second notification unit comprises one of a vibration generating unit which vibrates the self terminal, a light-emitting unit which emits light, a sounding unit which generates preset notification sound, a text display unit which displays text information indicating a notification content, and an image display unit which displays image information indicating the notification content.
