PTT SERVER, GATE APPARATUS, COMMUNICATION SYSTEM, PROGRAM AND COMMUNICATION METHOD
First Claim
1. A Push-to-Talk server (PTT server) for providing a half-duplex data transfer service wherein transmission data from a terminal which is connected to a packet communication network and which is assigned with a transmission right is broadcast at a time via the packet communication network to terminals of a group to which the terminal belongs, comprising:
- a unit which classifies terminals joining in a group into terminals of first kind having authority to assign the transmission right and terminals of second kind not having authority to assign the transmission right and thereby managing the respective terminals joining in the group; and
a unit which assigns the transmission right to another terminal belonging to the group according to designation from the terminal of first kind.

Abstract
A PoC communication system suitable for a broadcast use or the like is provided. In a communication system including a PoC server 30 and terminals 10 and terminals MS1 to MSn connectable to the PoC server 30, the PoC server 30 classifies the terminals into a terminal of first kind 10 having authority to assign a transmission right and terminals of second kind MS1 to MSn not having the authority to assign the transmission right and registers and manages each terminal joining in a group. The PoC server 30 assigns the transmission right to another terminal belonging to the group on the basis of designation from the terminal of first kind 10, and transmission data from the terminal assigned the transmission right is broadcast at a time via a packet communication network.

6. A communication system comprising a Push-to-Talk server (PTT server) connected to a packet communication network and a group of terminals connectable to the PTT server for providing a half-duplex data transfer service wherein transmission data from a terminal to which a transmission right is assigned by the PTT server is broadcast at a time via the packet communication network to terminals of a group to which the terminal belongs, wherein
the PTT server comprises: -
a unit which classifies terminals joining in an arbitrary group into terminals of first kind having authority to assign the transmission right and terminals of second kind not having authority to assign the transmission right and thereby managing the respective terminals joining in the group; and a unit which assigns the transmission right to another terminal belonging to the group according to designation from the terminal of first kind. - View Dependent Claims (7, 8, 9, 10)

11. A computer-readable medium storing a program to be executed by a computer constituting a Push-to-Talk server (PTT server) for providing a half-duplex data transfer service wherein transmission data from a terminal which is connected to a packet communication network and which is assigned with a transmission right is broadcast at a time via the packet communication network to terminals of a group to which the terminal belongs, the program causing the PTT server to perform:
-
processing for classifying terminals joining in a group into terminals of first kind having authority to assign the transmission right and terminals of second kind not having authority to assign the transmission right and thereby registering and managing the respective terminals joining in the group; and processing for assigning the transmission right to another terminal belonging to the group according to designation from the terminal of first kind. - View Dependent Claims (12, 13, 14)

15. A communication method to be implemented by use of a communication system comprising a Push-to-Talk server (PTT server) connected to a packet communication network and a group of terminals connectable to the PTT server for providing a half-duplex data transfer service wherein transmission data from a terminal to which a transmission right is assigned by the PTT server is broadcast at a time via the packet communication network to terminals of a group to which the terminal belongs, the method comprising:
-
classifying, by the PTT server, terminals joining in a group into terminals of first kind having authority to assign the transmission right and terminals of second kind not having authority to assign the transmission right and thereby registering and managing the respective terminals joining in the group; and assigning, by the PTT server, the transmission right to another terminal belonging to the group according to designation from the terminal of first kind. - View Dependent Claims (16, 17, 18, 19, 20, 21)
