Abstract

A gatekeeper of a voice over internet protocol (VoIP) system controls an incoming call directed to a group. The gatekeeper carries out the steps of: defining a plurality of terminals selected by an operator request as the group for taking a group call service, creating terminal information for the terminals and group information for a plurality of defined groups in the form of a table, and managing the table; and determining, using the table, whether the incoming call is directed to the group upon receiving the incoming call, generating a group call using the group information if the incoming call is directed to the group, and transmitting the group call to respective members belonging to the group.

Claims

1. A method for controlling an incoming call directed to a group in a gatekeeper of a voice over internet protocol (VoIP) system, comprising the steps of:

(a) defining a plurality of terminals selected by an operator request as a group for taking a group call service, creating terminal information for the selected plurality of terminals and group information for a plurality of defined groups in the form of a table, and managing the table; and

(b) determining, using the table, whether the incoming call is directed to the group upon receiving the incoming call, generating a group call using the group information when the incoming call is directed to the group, and transmitting the group call to respective members belonging to the group.

2. The method as set forth in claim 1, wherein the group information includes access numbers, a number of members belonging to the group, and the terminal information corresponding to the respective members belonging to the group.

3. The method as set forth in claim 2, wherein the terminal information includes terminal numbers corresponding to the respective members belonging to the group and other information.

4. The method as set forth in claim 1, wherein the group call includes destination group information, caller call identifiers (IDs), caller call states, and member information.

5. The method as set forth in claim 4, wherein the member information includes member call IDs, member call states, and other information.

6. A method for controlling incoming calls directed to groups in a gatekeeper of a voice over internet protocol (VoIP) system, comprising the steps of:

(a) defining a plurality of terminals selected by an operator request as a group for taking a group call service, creating terminal information for the selected plurality of terminals and group information for a plurality of defined groups in the form of a table, and managing the table;

(b) determining, using the table, whether each of the incoming calls is directed to the group upon sequentially receiving the incoming calls, generating a group call using the group information corresponding to the group when the incoming call is directed to the group, the group call including the group information and unique member call identifiers (IDs) for members belonging to the group, and storing the group call in a queue; and

(c) distinguishing different groups for the group calls stored in the queue, and independently transmitting the group call to the members in an idle state.

7. The method as set forth in claim 6, further comprising the step of:

(d) removing the group call from the queue when the group call is terminated.

8. The method as set forth in claim 7, wherein step (d) includes the steps of:

(d-1) removing the group call from the queue when one of the members belonging to the group receives the group call to proceed with the group call service;

(d-2) removing the group call from the queue when no member belonging to the group receives the group call, and timing out an alerting timer for the group call; and

(d-3) removing the group call from the queue when a caller terminates the group call in mid-course.

9. A method for controlling an incoming call directed to a group in a voice over internet protocol (VoIP) system, comprising the steps of:

(a) defining a plurality of terminals selected by an operator request as a group for taking a group call service;

(b) creating terminal information for the selected terminals and group information for a plurality of defined groups in the form of a table;

(c) determining, using the table, whether the incoming call is directed to the group upon receiving the incoming call;

(d) generating a group call using the group information when the incoming call is directed to the group; and

(e) transmitting the group call to respective members belonging to the group.

10. The method as set forth in claim 9, wherein the group information includes at least one of access numbers, a number of members belonging to the group, and the terminal information corresponding to the respective members belonging to the group.

11. The method as set forth in claim 9, wherein the terminal information includes terminal numbers corresponding to the respective members belonging to the group.

12. The method as set forth in claim 9, wherein the group call includes at least one of destination group information, caller call identifiers (IDs), caller call states, and member information.

13. The method as set forth in claim 10, wherein the member information includes at least one of member call IDs and member call states.

14. A method for controlling incoming calls directed to groups in a voice over internet protocol (VoIP) system, comprising the steps of:

(a) defining a plurality of terminals selected by an operator request as a group for taking a group call service;

(b) creating terminal information for the selected terminals and group information for a plurality of defined groups in the form of a table;

(c) determining, using the table, whether each incoming call is directed to the group upon sequentially receiving the incoming calls;

(d) generating a group call using the group information corresponding to the group when the incoming call is directed to the group;

(e) storing group calls in a queue;

(f) distinguishing different groups for the group calls stored in the queue; and

(g) transmitting the group call to members in an idle state.

15. The method as set forth in claim 14, further comprising the step of:

(h) removing the group call from the queue when the group call is terminated.

16. The method as set forth in claim 15, wherein step (h) includes the steps of:

(h-1) removing the group call from the queue when one of members belonging to the group receives the group call;

(h-2) removing the group call from the queue when no member belonging to the group receives the group call; and

(h-3) removing the group call from the queue when a caller terminates the group call in mid-course.

17. The method as set forth in claim 15, wherein step (h-2) further comprises timing out an alerting timer for the group call.

18. The method as set forth in claim 14, wherein step (g) comprises independently transmitting the group call to the members in the idle state.

19. The method as set forth in claim 14, wherein the group call includes at least one of the group information and unique member call identifiers (IDs) for members belonging to the group.
