Method in a digital network system for controlling the transmission of terminal equipment
First Claim
1. Method in a digital trunking network system for controlling the transmission of terminal equipment, which terminal equipment includes a PTT (Push-to-Talk) function in order to at least activate the transmission to be carried out to the said network system, and wherein the terminal equipment for voice control of the said PTT function also includes a VOX (Voice Operated transmission) feature, which can be activated/passivated and which is implemented by a VRE (Voice Recognition Engine) function, and in which method steps are performed the VRE function is used to search for an established keyword from an audio signal, the established keyword is recognised from the audio signal, a turn to transmit is requested from the network system, a turn to transmit is received from the network system, the transmission is connected and the granted turn to transmit is indicated, the transmission is carried out, and the transmission is passivated, characterized in that in the said VOX feature before the said VRE function the audio signal is monitored by a VAD (Voice Activity Detection) function arranged in connection with terminal equipments, and whereby when activating the said VOX feature in the terminal equipment steps are performed before the said partial steps the terminal equipment'"'"'s incoming audio signal is processed with the VAD function searching it for a signal form in accordance with an established criterion, and when a signal form according to the established criterion is detected in the audio signal, the said VRE function is activated to search for an established keyword.

Abstract
The invention concerns a method in a digital network system for controlling the transmission of terminal equipments. Terminal equipment includes a PTT (Push-to-Talk) function in order to at least activate the transmission to be carried out to the said network system, and wherein the terminal equipment for voice control of the said PTT function also includes a VOX (Voice Operated transmission) feature, which can be activated/passivated and which is implemented by a VRE (Voice Recognition Engine) function. In the method stops are performed—the VRE function is used to search for an established keyword from an audio signal,—the established keyword is recognised from the audio signal,—a turn to transmit is requested from the network system,—a turn to transmit is received from the network system,—the transmission is connected and the granted turn to transmit is indicated,—the transmission is carried out, and—the transmission is passivated. In the said VOX feature before the said VRE function the audio signal is monitored by a VAD. (Voice Activity Detection) function arranged in connection with terminal equipments, and whereby when activating the said VOX feature in the terminal equipment steps are performed before the said partial steps the terminal equipment'"'"'s incoming audio signal is processed with the VAD function searching it for a signal form in accordance with an established criterion, and—when a signal form according to the established criterion is detected in the audio signal, the said VRE function is activated to search for an established keyword.

7. Method in a digital network system for controlling the transmission of terminal equipment, wherein the said network system is arranged in connection with an All-IP infrastructure equipped with a server, and the said terminal equipment is arranged to support the PoC (Push-to-talk over Cellular) feature/service and wherein the terminal equipment includes a PTT (Push-to-Talk) function to at least activate the transmission to be carried out to the said network system, and wherein the terminal equipment for voice control of the said PTT function also includes a VOX (Voice Operated transmission) feature, which can be activated/passivated and which is implemented by a VRE (Voice Recognition Engine) function, and in which method the following steps are performed while carrying out the transmission with the PTT function
the VRE function is used to search for an established keyword from the audio signal, the established keyword is recognised from the audio signal, the transmission is activated and the transmission is passivated, characterized in that in the said VOX feature before the said VRE function the audio signal is monitored by a VAD (Voice Activity Detection) function arranged in connection with the terminal equipment, and whereby when activating the said VOX feature at the terminal equipment the following steps are performed before the said partial steps the terminal equipment'"'"'s incoming audio signal is processed with the VAD function searching it for a signal form in accordance with an established criterion, and when a signal form in accordance with the established criterion is found in the audio signal, the transmission of the terminal equipment is activated carrying out the said partial steps.
