    Abstract: A method is employed by a central controller of a radio communications system, which method provides for sustaining a predetermined level of communication service. The system includes a plurality of voice channels which are allocated among a plurality of subscribers (108-112) using a first control channel (102). In a preferred embodiment, at least one of the voice channels (104, 106) is also control-capable. The method includes evaluating (504) a current loading condition, and comparing (504) this loading condition with an upper loading threshold. Where appropriate, the controller assigns (506) one of the control-capable voice channels as a temporary control channel.

    Abstract: Upon a first communication unit (213) initiating a call request for a 2-party call with a second communication unit (215), a call server (235) identifies respective multicast IP addresses (MC1, MC2) associated with the source and target. If the first communication unit (213), or associated site (205) desires to send payload to the second communication unit (215), it addresses the payload to the multicast IP address (MC2) of the second communication unit, and the second communication unit (215), or associated site (206) joins the multicast address (MC2) to receive the payload. Conversely, if the second communication unit (215), or associated site (206) desires to send payload to the first communication unit (213), it addresses the payload to the multicast IP address (MC1) of the first communication unit, and the first communication unit (213), or associated site (205) joins the multicast address (MC1) to receive the payload.

    Abstract: A method for providing push-to-talk (PTT) service between PTT enabled devices (102) and non-PTT enabled devices (116) is disclosed. First, the non-PTT enabled device is registered at a PTT interworking agent (110). Then, signaling data is received at an interface (110) in a first format. The signaling data includes an identifier corresponding to one or more destination phones. Next, the signaling data in the first format is converted to a second signaling protocol at the PTT interworking agent. The push-to-talk signaling information is sent to a push-to-talk server (106) and a destination address is located for each of the one or more phones associated with the signaling data. The signaling data is then routed to the one or more phones.

    Abstract: A network (100) of trunked communication systems (A, B and C) supports communication with communication unit (112) roaming about the geographic area covered by said network by having control computers (106) associated with the individual trunking systems communicate directly with each other, transferring information about the roaming communication unit between themselves. The identification and privileges of the roaming communication unit (112) are passed about the network (100) by the computers (106) giving the roaming communication unit the ability to exchange data across the network directly, or, through telephone interconnects in the various trunking systems, to communicate via a voice message through the public switch telephone network (108A, 108B, 108C).
