The present invention relates to a group broadcasting system using a PTT mobile terminal and a method thereof, which can broadcast a call broadcast such as an immediate alert to a selective or fixed user group in real time through a PTT supporting communication network.

PTT service that can use a mobile phone as a walkie-talkie is attracting attention from all over the world.

PTT service is a kind of walkie-talkie-like feature that allows you to talk to the person you want at the touch of a button, as well as one-to-one calls and multiple calls, such as conference calls on landlines. Say something that several people can hear at the same time.

While the existing mobile phone makes a call without knowing whether the other party can receive it, the PTT service shows the phone number on the mobile phone screen like MSN Messenger. Call waiting time is short and easy to use. It is also attractive to people with high call rates due to its lower price than regular calls.

  Compared to general mobile phones, call waiting time is shorter, easier to use, and relatively cheaper.

To use the PTT service, a mobile phone supporting the PTT function must be secured.

Users can use a PTT-enabled mobile phone as a walkie-talkie without having to ear it like a normal mobile phone.

 Because of these advantages, it is desperately required by users who require emergency calls or on-site construction sites, large industrial complexes, university campuses, etc., and the demand is continuously increasing in foreign countries.

The mobile phone supporting the PTT function needs to be used for services providing urgent info such as group multiple calls as well as alarms of various accidents and disasters.
