17. A timer controlling method for a PT (push-to) client of a mobile terminal in a system, the mobile terminal including a device management client, the PT client including a talk burst request timer, the system including a PT server, a device management server, and an application management server authority, the method comprising:

transmitting state information from the PT server to the application management server authority;

determining, by the application management server authority, a time value for the talk burst request timer based on the state information;

transmitting the time value from the application management server authority to the device management server;

transmitting the time value from the device management server to the device management client through a session established between the device management server and the device management client;

updating a management object of the device management client with the received time value; and

updating a previously-set time value of the talk burst request timer of the PT client with the received time value.

18. The method of claim 17, wherein the session uses a device management (DM) provisioning method.

19. The method of claim 17, further comprising:

performing, by the PT client, a transmission and/or a retransmission of a talk burst request message using the talk burst request timer having the updated time value.

20. 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,
