METHOD AND DEVICES FOR PROVIDING A PUSH-TO-TALK COMMUNICATION BETWEEN TWO USER TERMINALS IN A COMMUNICATIONS NETWORK

摘要

By signalling information for establishing the push-to-talk communication of a first terminal with a switching node in a mobile telecommunications network, establishing a usable link with the switching node from the first terminal and then establishing a usable link with at least one other terminal from the switching node, a push-to-talk connection is established.
