Push-to-Talk over Cellular (PoC) system in mobile communication network, such as TD-SCDMA, is considered to have more wide coverage and more flexibility than traditional trunk communication systems. It is ideal for group communication in many cooperative work environments. But the foremost block for wider application of PoC system is the longer session setup latency comparing to other trunk communication...
Push-to-Talk over Cellular (PoC) system is ideal for group communication in many cooperative work environments because of its wider coverage and more flexibility than traditional trunk communication systems. The long session-setup-delay is an important problem that must be solved before the commercial application of PoC system. Many research works have been done to solve it in some mobile networks,...
In view of the development of the Push to talk over Cellular (PoC), this paper proposes two different network schemes, and every network unit function is introduced. Then the communication performance is simulated about the two schemes. Lastly, the communications of the PoC service based on TD-SCDMA network is simulated by computer. By simulation we know it is able to realize the PoC service based...
