摘要： A roaming gateway for support of advanced voice services while roaming in wireless communications systems. The roaming gateway supports push-to-talk (P2T) calls, or other advanced voice services, when P2T subscribers roam from their home network (i.e., a network operated by their service provider where the subscriber's profile resides) into a foreign network (i.e., a network operated by another service provider). The roaming gateway is a specialized version of a real-time exchange that is located in the home network and is connected to mobile switching centers in foreign networks, so that the mobile switching centers in the foreign networks need not be programmed for the advanced voice services.

摘要： 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 a Real-Time Exchange (RTX) that interfaces to at least one Mobile Switching Center (MSC) in the cellular mobile telephone network to provide instant two-way half-duplex voice messaging within a group of users. In the Hybrid PTT function, first or initial talkbursts or volleys are transmitted by the RTX from an originating mobile to terminating mobiles on pre-established Internet Protocol (IP) sessions between the RTX and the mobiles. In addition, circuit channels are established by the RTX with the mobiles through the MSC in parallel with the first talkburst or volley. Thereafter, second or subsequent talkbursts or volleys are transmitted by the RTX from the originating mobile to the terminating mobiles on the circuit channels.

摘要： 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.
