A client-side design and implementation for push to talk over cellular service
نویسندگان
چکیده
This paper proposes a client architecture for the Push to Talk over Cellular (PoC) service based on the Open Mobile Alliance (OMA) PoC specifications v1.0 release. We show that most standard VoIP modules can be reused for the PoC client, and the VoIP software can be easily extended to support PoC service. Then we present the detailed message flows between the PoC client and other network entities in the PoC system. A PoC client prototype has been implemented in the Industrial Technology Research Institute (ITRI) and National Chiao-Tung University (NCTU) Joint Research Center.

NTP-PoCT: a conformance test tool for push-to-talk over cellular network
Push-to-talk over Cellular (PoC) provides walkie– talkie like service in the cellular telecommunications network [9]. In this service, several predefined PoC group members participate in one PoC session. Since the PoC session is half-duplex, only one group member speaks at a time, and the others listen. Therefore, a user must ask for the permission to speak by pressing the push-to-talk button. ...
