Abstract: A system and method for optimizing large group calling using unicast and multicast transport bearers for Push-to-talk-over-Cellular (PoC). One or more servers interface to a wireless communications network to perform advanced voice services for mobile units therein, including the PoC call session. The servers and mobile units communicate with each other using control messages, and the servers switch voice messages between the mobile units. At least one of the servers manages the PoC call session by acting as an arbitrator, and controls the sending of the control messages and the voice messages to and from the mobile units. The server performs unicast and multicast delivery of the control messages and the voice messages to and from the mobile units, thereby enabling large group calling involving a large number of participants with optimized use of network and server resources.

Abstract: A system and method for providing radio access network (RAN) aware service delivery for Push-to-talk-over-Cellular (PoC) networks, wherein at least one of the servers performs an effective presence delivery method that reduces presence notifications delivered to the mobile units participating in the advanced voice services, by optimizing usage of service delivery mechanisms in the wireless communications network for delivery of presence notifications. The effective presence delivery method may comprise: throttling the delivery of the presence notifications; avoiding simultaneous dispatch of the presence notifications to multiple watchers located in the same cell or group of cells of the wireless communications network; or the server delaying sending the presence notifications for a mobile unit until the mobile unit triggers the server.

Abstract: A system and method for improved push-to-talk (PTT) communications performance includes a PTT application server receiving a request from a client user equipment (UE) device to access PTT services over a carrier network. The PTT application server measures, determines, predicts, or otherwise detects congestion in a cell of the carrier network servicing the client UE device. In a representative aspect responsive to detecting a value of congestion, the PTT server modifies one or more PTT call parameters, transmits a modified PTT call parameter to the UE device, and reduces the number of signals subsequently transmitted to the UE device. The modified PTT call parameter may be a codec selection for encoding/decoding PTT voice data. Subsequently transmitted signals may include acknowledgement signals, retry requests, bundled frames, or the like.
