Abstract

A system and method for changing a value of a talk burst control timer, are provided. According to an embodiment, there is provided a method of controlling a talk burst for at least one PT (push-to) client each having at least one talk burst control timer, the method comprising: providing, by a device management server or a PT server, at least one time value for the at least one talk burst control timer, to the at least one PT client, and updating the at least one talk burst control timer in the at least one PT client with the at least one time value.

Claims

1. A method of controlling a talk burst for at least one PT (push-to) client each having at least one talk burst control timer, the method comprising:

providing, by a device management server or a PT server, at least one time value for the at least one talk burst control timer, to the at least one PT client; and

updating the at least one talk burst control timer in the at least one PT client with the at least one time value,

wherein the providing step includes,

including the at least one time value in a real-time transport control protocol (RTCP) message, which is to be sent from the PT server to a certain PT client after a session is established between the PT server and the certain PT client, and

transmitting the RTCP message including the at least one time value from the PT server to the certain PT client, so that at least one talk burst request timer of the certain PT client can be updated with the at least one time value in the updating step, and

wherein the RTCP message is a talk burst control protocol (TBCP) message.

2. A system for controlling a talk burst, the system comprising:

a device management server;

a PT (push-to) server; and

at least one PT client, each PT client having at least one talk burst control timer and provided in a mobile terminal,

wherein the at least one PT client receives at least one time value for the at least one talk burst control timer from the device management server or the PT server, and the at least one talk burst control timer in the at least one PT client is updated with the at least one time value,

wherein the PT server includes the at least one time value in a real-time transport control protocol (RTCP) message, which is to be sent from the PT server to a certain PT client after a session is established between the PT server and the certain PT client, and transmits the RTCP message including the at least one time value from the PT server to the certain PT client,so that at least one talk burst request timer of the certain PT client can be updated with the at least one time value, and

wherein the RTCP message is a talk burst control protocol (TBCP) message.
