First Claim
1. A method for distributing media data in PoC (push-to-talk over cellular) applied to a PoC system, the PoC system comprises a plurality of clients, a controlling server and a first participating server;
- the method comprising the following steps;
sending a request to establish a communication group from the controlling server;
receiving responses of agreeing with the request at the controlling server;
sending a message from the controlling server to the first participating server in order to establish a media receiving port in the first participating server if at least two clients among all the clients joining the communication group belong to the first participating server and accept the management thereby; and
delivering the media data from the controlling server to the media receiving port in the first participating server when the first participating server wishes to deliver the media data to the clients managed by the first participating server after the controlling server has received the response of having established the media receiving port already.

Abstract
The present invention provides a PoC system (push-to-talk over cellular system) and a method for distributing media data in PoC. The PoC system includes a plurality of clients, a controlling server and a first participating server. In the present invention, since a media receiving port is established in the first participating server which manages at least two clients at the same time, and when a media data is going to be distributed to the clients managed by the first participating server, the controlling server delivers the media data to the media receiving port only. In addition, a multicast addressing technology is further used in the first participating server, therefore, the path of delivering media data is changed and the efficiency of media data delivery during a communication is improved.
