PoC COMMUNICATION SYSTEM, PoC TERMINAL, PoC SERVER, AND ADDITIONAL SERVICE UTILIZATION METHOD USED IN THEM

The present invention relates to a PoC communication system, a PoC terminal, a PoC server, and an additional service usage method used therefor, and particularly to an additional service in a PoC (Push to Talk over Celluler) communication system.

In recent years, it has become possible to use various additional services such as telephone number notification / non-notification, voice message recording, PoC communication, etc., in addition to making a call, and these additional services have become widespread. I'm doing it.

PoC is like a walkie-talkie using IP (Internet Protocol), and calls are one-way (see, for example, Patent Document 1). In addition, PoC can group the other party to talk to like IM (Instant Messaging), and can see the status of the other party. Therefore, in PoC, a call can be made by selecting the other party (one person or group) in the call state and pressing the call button. In other words, PoC is a transceiver mode of a mobile phone, there is no need to dial the number of the call destination, the time to connect is short, and it is possible to make a call at multiple locations at the same time.

In PoC, it is often set at a lower price than ordinary calls. In addition, as the operation procedure, a call is made by opening a call destination list prepared separately from the normal telephone directory, selecting and deciding the other party, and pressing the call button. At that time, if a plurality of call destinations are selected, the call becomes a multipoint call. However, in the current PoC, the call destination is limited to terminals of the same carrier, but with the progress of technology in this field, multipoint calls between different carriers are also being considered.
