Abstract

A server servicing a plurality of mobile communication systems for half-duplex communication is provided. The server comprises a transceiver to send and receive communication signals; a processor in operational relationship with the transceiver for processing executable code stored in a storage medium accessible by the processor, the executable code configured to cause the processor to detect a time duration in which a user continuously activates a half-duplex function.

Claims

1. A method for allocating a talk burst in a push-to-talk (PTT) communication system, the method comprising:

receiving a first talk burst request from a first PTT terminal from among a plurality of PTT terminals in the PTT communication system;

receiving a second talk burst request from a second PTT terminal from among the plurality of PTT terminals in the PTT communication system;

granting the first talk burst request, in response to determining that the talk burst is unallocated and a first priority level associated with the first PTT terminal is higher than a second priority level associated with the second PTT terminal; and

denying the first talk burst request, in response to determining that the talk burst is allocated or the first priority level is less than the second priority level,

wherein the first talk burst request is periodically retransmitted by the first PTT terminal, while a PTT request actuator on the first PTT terminal is continuously activated and the first talk burst request is denied.

2. The method of claim 1, wherein the receiving, granting, and denying of the first talk burst request are performed by a PTT server.

3. The method of claim 1, further comprising determining the first priority level based on length of time the PTT request actuator on the first PTT terminal is continuously activated.

4. The method of claim 1, further comprising changing the first priority level, in response to denying the first talk burst request.

5. The method of claim 1, further comprising resetting the first priority level to an initial value, in response to the PTT request actuator on the first PTT terminal being released.

6. The method of claim 1, further comprising determining the first priority level on a first-come, first served basis.

7. The method of claim 1, further comprising determining the first priority level based on number of times the PTT actuator on the first PTT terminal is activated.

8. The method of claim 1, wherein the first talk burst request is denied through at least one of an audio, a visual, or tactile means.

9. The method of claim 1, wherein the first talk burst request is periodically retransmitted by the first PTT terminal based on a combination of different time periods, while the PTT request actuator on the first PTT terminal is continuously activated and the first talk burst request is denied.

10. The method of claim 1, wherein the first talk burst request is periodically retransmitted by the first PTT terminal relatively frequently at first and less frequently as time passes, while the PTT request actuator on the first PTT terminal is continuously activated and the first talk burst request is denied.

11. A system for allocating a talk burst in a push-to-talk (PTT) communication system, the system comprising:

means for receiving a first talk burst request from among a first PTT terminal from a plurality of PTT terminals in the PTT communication system;

means for receiving a second talk burst request from a second PTT terminal from among the plurality of PTT terminals in the PTT communication system;

means for granting the first talk burst request, in response to determining that the talk burst is unallocated and a first priority level associated with the first PTT terminal is higher than a second priority level associated with the second PTT terminal; and

means for denying the first talk burst request, in response to determining that the talk burst is allocated or the first priority level is less than the second priority level,

wherein the first talk burst request is periodically retransmitted by the first PTT terminal, while a PTT request actuator on the first PTT terminal is continuously activated and the first talk burst is denied.

12. The system of claim 11, wherein a PTT server comprises the means for the receiving, granting, and denying the first talk burst request.

13. The system of claim 11, further comprising means for determining the first priority level based on length of time the PTT request actuator on the first PTT terminal is continuously activated.

14. The system of claim 11, farther comprising means for changing the first priority level, in response to denying the first talk burst request.

15. The system of claim 11, further comprising means for resetting the first priority level to an initial value, in response to the PTT request actuator on the first PTT terminal being released.

16. The system of claim 11, further comprising means for determining the first priority level on a first-come, first served basis.

17. The system of claim 11, further comprising means for determining the first priority level based on number of times the PTT actuator on the first PTT terminal is activated.

18. The system of claim 11, wherein the first talk burst request is denied through at least one of an audio, a visual, or tactile means.

19. The system of claim 11, wherein the first talk burst request is periodically retransmitted by the first PTT terminal based on a combination of different time periods, while the PTT request actuator on the first PTT terminal is continuously activated and the first talk burst request is denied.

20. The system of claim 11, wherein the first talk burst request is periodically retransmitted by the first PTT terminal relatively frequently at first and less frequently as time passes, while the PTT request actuator on the first PTT terminal is continuously activated and the first talk burst request is denied.
