Abstract

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.
