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.

Abstract: A communication system is provided that sets up a group call, originated in a first originating network, in a second originating network when insufficient resources are available in the first originating network, wherein the first originating network is one of a narrowband network and a broadband network and the second originating network is the other network of the narrowband and broadband networks. An infrastructure device of the first originating network receives a first group call request from an originating mobile device and, in response to receiving the request, determines that insufficient resources are available in the first originating network for allocation to the mobile device for the group call. In response to determining that insufficient network resources are available, the infrastructure device arranges to set up an originating leg of the group call for the originating mobile device in the second originating network.

Abstract: A method and apparatus for improved resource allocation in ad hoc group calls includes receiving a request for an ad hoc group call with another push-to-talk (PTT) system between a plurality of subscriber units comprising a plurality of Project 25 (P25) subscriber units; allocating resources with the another PTT system using an Inter Radio Frequency Subsystem Interface (ISSI) network to network interface (NNI); and identifying the ad hoc group call as a single logical call for the plurality of P25 subscriber units on the ISSI NNI. This can also include allocating a single channel for the plurality of P25 subscriber units identified as the single logical call.
