Abstract: Systems and methods for multiple mode push-to-x group calls. One example embodiment provides a push-to-X server. The push-to-X server includes a communication interface communicatively coupled to a communication network and an electronic processor. The electronic processor receives, via a unicast uplink channel, a group call request from a first subscriber unit of the communication network. The electronic processor receives, from the first subscriber unit, a push-to-X data stream. The electronic processor receives a unicast channel request from a second subscriber unit of the communication network. In response to receiving the unicast channel request, the electronic processor establishes a unicast channel resource with the second subscriber unit. The electronic processor transmits the push-to-X data stream to the second subscriber unit via the unicast channel resource and transmits the push-to-X data stream to a plurality of subscriber units via a broadcast media bearer channel.

Abstract: Techniques for dynamically changing the interval to receive data from an evolved multimedia broadcast multicast service bearer are provided. A wireless device may monitor a first bearer channel, the first bearer channel sending control messages at a first interval. An indication to monitor a second bearer channel may be received, the second bearer channel sending control messages at a second interval. The mobile device may monitor the second bearer channel at the second interval.

Abstract: A method to provide ambient listening on target devices is shown. The ambience listening can be initiated by the listener or by the target device. When a console initiates an Ambience Listening (AL) call regarding a target and the target is logged into more than one device, the PTT server presents the console with a list of all concurrent devices of that user. The console is presented with additional information regarding the target, such as the location, role selected by the user on each device, and the user's operational status on each device. The operational status includes, for example, an emergency state. This enables the console to setup one or more ambience listening session with one or more appropriate devices.
