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.

A system and method for providing dynamic quality-of-service (QoS) for Push-to-Talk (PTT) services in a wireless communications network. One or more servers interface to the wireless communications network to perform the PTT services for mobile units therein. Both the servers and the mobile units communicate with each other using control messages transmitted across bearers in the wireless communications network, and at least one of the servers transmits media streams comprised of voice messages for the PTT services between the mobile units across the bearers in the wireless communications network. At least one of the servers sets up a dedicated bearer in the wireless communications network for at least one of the mobile units, wherein the dedicated bearer has a specified quality of service (QoS) for transmission of at least the media streams to the mobile unit. The dedicated bearer may be static or dynamic.

Method for providing dynamic quality of service for push-to-talk service

An embodiment method includes receiving, by a notification service running on a processor, a notification from a first component of a push-to-talk (PTT) platform. The notification is for transmission to a PTT client. The method further includes determining, by the notification service, an access transport type used by the PTT client to communicate with the PTT platform, and selecting, by the notification service, a second component to transmit the notification to the PTT client. Selecting the second component is in accordance with the access transport type used by the PTT client. The method further includes transmitting, by the notification service, the notification to the second component.
