Abstract
Aspects of mobile communication for establishing a receive-only group communication, such as a Push-to-Talk (PTT) call or multicast call with a plurality of wireless communication devices that are in a receive-only mode are disclosed. When a group call between wireless communication devices starts from an originating device, in one embodiment indicating a receive-only group with which a group call is to be established, one or more receive-only wireless communication devices are determined and invited to participate in the group call. The traffic channel to the receive-only wireless communication device is transitioned to a uni-directional, forward-only traffic channel such that media is provided from the originating wireless communication device to the receive-only wireless communication device via the uni-directional traffic channel.
