1. A system for managing talk burst authority in a mobile communication terminal for a Push-To-Talk (PIT) service, the system comprising:
- a voice activity detector for generating a trigger signal when a voice is input via a microphone of the mobile communication terminal;
a voice recognition processor for performing a voice recognition operation to recognize the voice input to determine if the voice input corresponds to a voice command for requesting a talk burst authority or releasing the talk burst authority;
a buffer for temporarily storing the voice input; and
a processing unit for detecting the trigger signal, initiating operation of the voice recognition processor when the trigger signal is detected, terminating the operation of the voice recognition processor after a predetermined time period according to the detected trigger signal, and controlling management of the talk burst authority by transmitting a talk burst request message or a talk burst release message to a PIT sewer according to a result of the voice recognition operation.

Abstract
A method for managing talk burst authority of a mobile communication terminal for a PTT service comprises detecting a trigger signal generated from a voice activity detector in response to an audio input; activating a voice recognition processor to process the audio input; deactivating the corresponding voice recognition processor after a predetermined time has lapsed; transmitting a talk burst request message to the PTT server, when the audio input is for requesting permission to speak; transmitting the audio input to the PTT server; and storing the audio input in a buffer.

9. A method for managing talk burst authority of a mobile communication terminal for a PTT service, the method comprising:
-
generating a trigger signal in a voice activity detector when a voice is input via a microphone; performing a voice recognition operation on the voice input in a voice recognition processor to determine if the voice input corresponds to a voice command for requesting a talk burst authority or releasing the talk burst authority; storing the voice input in a buffer; detecting the trigger signal generated by the voice activity detector in a processing unit; controlling the voice recognition processor via a main processing unit, such that the voice recognition operation is initiated when the trigger signal is detected and the voice recognition operation is terminated after a predetermined time period according to the detected trigger signal; and transmitting a talk burst request message or a talk burst release message to a PTT server according to a result of the voice recognition operation. - View Dependent Claims (10, 11, 12, 13, 14, 15)
