Abstract

A method for managing a talk burst in a PTT service system comprises: allocating, by a PTT server, master authority to a particular PTT client; and controlling, by the PTT server, another PTT clients according to a talk burst management procedure selected by the PTT client having the master authority. The PTT server allocates the master authority to the PTT client initiating a session and the PTT client having the master authority freely controls the talk burst management procedure, so that session establishment can be smoothly controlled.

Claims

1. A method for managing a talk burst in a group communication, the method comprising:

a PTT (Push To Talk) server allocating master authority to a PTT client that requested session establishment; and

the PTT client having been allocated master authority determining a management procedure by selecting at least one of a plurality of management procedures; and

the PTT server controlling at least one specific PTT client established in a session with the PTT client having been allocated master authority according to the determined management procedure of the PTT client having master authority,

wherein the plurality of management procedures comprise;

allocating a talk burst once to each of the at least one specific PTT client established in the session with the PTT client having been allocated master authority,

releasing the talk burst of a specific PTT client having previously been allocated the talk burst when the specific PTT client has exceeded use of the talk burst beyond a predetermined time,

preventing the talk burst of the at least one specific PTT client,

allocating master authority to a third party PTT client,

releasing the talk burst allocation to the third party PTT client and allocating priority for a next talk burst to the PTT client having been allocated master authority.

2. A server of a group communication system, the server comprising:

a transceiver to send and receive communication signals;

a processor cooperating with the transceiver; and

a storage medium storing instructions executable by the processor to perform;

allocating master authority to a particular user terminal that requested session establishment with other user terminals,

sending the floor control commands to the other terminals to perform the floor control procedures

receiving floor control commands from the particular user terminal to handle floor control procedures for other the user terminals having a session established and,

wherein the floor control commands are sent according to a management procedure determined by the particular user terminal from at least one of a plurality of management procedures,

wherein the plurality of management procedures comprise;

allocating a talk burst once to each of the other user terminals having the session established with the particular user terminal,

releasing the talk burst of a specific one of the other user terminals having been previously allocated the talk burst when the specific one of the other user terminals has exceeded use of the talk burst beyond a predetermined time,

preventing the talk burst of the other user terminals,

allocating master authority to a third party terminal, and

releasing the talk burst allocation to the third party terminal and allocating priority for another talk burst to the particular user terminal,

and wherein the processor controls the other user terminals having a session established with the particular user terminal having master authority.

3. The server of claim 2, wherein the floor control procedures allow fair access to multiple user terminals.

4. The server of claim 2, wherein the master authority allocated to the third party terminal is released and returned to the particular user terminal.

5. The server of claim 2, wherein the group communication system supports a push-to-talk function.

6. A user terminal of a group communication system, the user terminal comprising:

a transceiver to send and receive communication signals;

a processor cooperating with the transceiver; and

a storage medium storing instructions executable by the processor for,

receiving master authority from a server after requesting session establishment with other user terminals, determining a floor control command from a plurality of floor control commands, and sending the floor control command to at least one other user terminal via the server to handle floor control procedures for at least one other user terminal having a session established with the user terminal, and wherein the plurality of floor control commands comprise;

allocating a talk burst once to each of the at least one other user terminal having a session established with the user terminal,

releasing the talk burst of a specific one of the other user terminals having been previously allocated the talk burst when the specific one of the other user terminals has exceeded use of the talk burst beyond a predetermined time,

preventing the talk burst of one of the other user terminals,

allocating master authority to a third party user terminal, and

releasing the talk burst allocation to the third party user terminal and allocating priority for a next talk burst to the user terminal,

and wherein the server controls the at least one other user terminal having a session established with the user terminal.

7. The user terminal of claim 6, wherein the floor control procedures allow fair access to multiple user terminals.

8. The user terminal of claim 6, wherein the master authority allocated to the third party user terminal is released and returned from the third party user terminal.

9. The user terminal of claim 6, wherein the group communication system supports a push-to-talk function.
