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.

In an embodiment, a method includes: accessing, by a push to talk (PTT) server, a PTT session with a PTT client operating in a first network; detecting, by the PTT server, a transition by the PTT client from the first network to a second network, the second network having a lower throughput or a higher latency than the first network; and adapting, by the PTT server, one or more parameters of a plurality of communication protocols in response to detecting the transition by the PTT client from the first network to the second network, the communication protocols being host layer protocols used by the PTT server to communicate with the PTT client.

A network-to-network interface (NNI) device, including at least one push-to-talk (PTT) interface adapter, a processor connected to the at least one PTT interface adapter, and a non-transitory computer readable medium connected to the processor. The non-transitory computer readable medium has stored thereon instructions that, when executed by the processor, cause the NNI device to receive a first PTT communication in a first PTT format through the at least one PTT interface adapter from a first PTT system, translate the first PTT communication into a second PTT communication in one or more second PTT formats, and transmit the second PTT communication through the at least one PTT interface adapter to one or more second PTT systems.

Network-to-network interface gateway system for push-to-talk-over-cellular service

A system and method to leverage Web Real-Time Communication (WebRTC) for implementing Push-to-Talk (PTT) solutions. One or more servers interface to a communications network to perform advanced voice services for one or more wireless or wired user devices, wherein the advanced voice services include a two-way half-duplex voice call within a group of the user devices comprising a PTT call session. At least one of the user devices communicates with at least one of the servers during the PTT call session using a WebRTC connection, and at least the media streams for the PTT call session are transmitted between the server and the user device using the WebRTC connection.

An embodiment method includes receiving, by a server of a telecommunications services platform, a request for a first call session quality indicator (CSQI) of a first client device, determining, by the server, first channel parameters of a first channel between the server and the first client device, and calculating, by the server, the first CSQI of the first client device in accordance with the first channel parameters of the first channel. The method further includes transmitting, by the server, the first CSQI to the first client device and receiving, by the server, a call session initiation request from the first client device after transmitting the first CSQI to the first client device.

System and method for implementing call session quality indicator

A system and method for supporting multiple simultaneous connections to different access networks for use in Push-to-talk-over-Cellular (PoC). One or more servers interface to a plurality of wireless communications networks 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 frames 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 frames to and from the mobile units. At least one of the mobile units and at least one of the servers use multiple simultaneous connections to the plurality of wireless communications networks to communicate with each other.

A predictive wakeup function for Push-to-Talk-over Cellular (PoC) call setup optimizations in a cellular mobile phone network. In performing the predictive wakeup for call setup optimizations, an originating mobile transmits an event trigger to a real-time exchange that interfaces to a mobile switching center in the cellular mobile phone network. The real-time exchange transmits a wakeup message to one or more terminating mobiles of predicted participants, in order to transition the terminating mobiles of the predicted participants from a dormant state to an active state prior to a call being setup with the terminating mobiles of the predicted participants. The terminating mobiles of the predicted participants are identified by a predictive wakeup mechanism before the originating mobile sends a list of one or more terminating mobiles of actual participants to the real-time exchange. The predicted participants may be determined based on static or dynamic information, including heuristics involving calling patterns.
