摘要：Push-to-Talk (PTT) is a useful capability for rapidly deployable wireless mesh networks used by first responders. PTT allows several users to speak with each other while using a single, half-duplex, communication channel, such that only one user speaks at a time while all other users listen. This paper presents the architecture and protocol of a fault tolerant PTT service for PTT in all IP Networks.
