Patent ID: 8514754

Claim:
A method for use in a mobile communication device for controlling discontinuous transmission operations in a generic access network (GAN), the method comprising the acts of: sending, via the GAN, a registration message to a GAN controller (GANC); in response to sending the registration message, receiving, via the GAN and from the GANC, a registration acceptance message which includes a discontinuous transmission (DTX) indication; after receiving the registration acceptance message, establishing a connection with the GANC, via the GAN and over a wireless communication link with a wireless access point of the GAN, for the communication of voice data of a voice communication session which is provided via a core network of a mobile telecommunications network which communicates with the GANC; performing DTX functions during the voice communication session for the communication of the voice data over the wireless communication link of the GAN in response to identifying that the DTX indication of the registration acceptance message indicates that DTX functions are instructed or supported; and refraining from performing the DTX functions during the voice communication session for the communication of the voice data over the wireless communication link in response to identifying that the DTX indication of the registration acceptance message indicates that DTX functions are not instructed or supported.
