20100142414 | HYBRID PUSH-TO-TALK FOR MOBILE PHONE NETWORKS - A Hybrid Push-to-Talk (PTT) function for use in wireless communications networks, such as cellular mobile telephone networks. The cellular mobile telephone network includes at least one Real-Time Exchange (RTX) that interfaces to at least one Mobile Switching Center (MSC) in the cellular mobile telephone network to provide advanced voice services therein, wherein the advanced voice services provide instant two-way half-duplex voice messaging within a group of users of the cellular mobile telephone network, which is known as the Hybrid PTT function. In the Hybrid PTT function, a first talkburst or volley is transmitted by the RTX from an originating mobile to one or more terminating mobiles on one or more pre-established Internet Protocol (IP) sessions between the RTX and the mobiles. In addition, one or more circuit channels are established by the RTX with the mobiles through the MSC in parallel with the first talkburst or volley.
