Communication right assigning method for push-to-talk-over-cellular communication system, involves denying communication right if right is already distributed to subscriber, and giving communication right if right is not distributed

摘要

The method involves coupling several communication conference meetings with one another and receiving a request for a communication right. A determination is made if the communication right is already distributed to a subscriber of one of the communication conference meetings. The communication right is denied if the right is already distributed and the communication right is given if the right is not distributed. An independent claim is also included for a communication conference meeting server for initialization of the communication conference meeting.
