ABSTRACT:
Outside services are connected to user equipment via a push-to-talk (PTT) session by signing-up the user equipment with the outside service, generating a request to establish the PTT session between the user equipment and the outside service, establishing the PTT session, and transmitting media from the outside service to the user equipment via the PTT session. The request to establish the PTT session may be either from the outside service or from the user equipment. The establishment of the PTT session is initiated from within the network. Further, the PTT session may be either delayed or in real-time in relation to the request to establish the PTT session.
