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 talk burst timer operations for a terminal that communicates with a network, the method performed by the network and comprising: receiving at least one talk burst request from the terminal; and sending, to the terminal, at least one time value for at least one talk burst control timer of the terminal, wherein the time value is decided with consideration of network environment information, and wherein the time value is sent by using a device management (DM) provisioning method.

Claims

1. A method of controlling talk burst timer operations in a terminal that communicates with a network, the method performed by the terminal and comprising:

sending at least one talk burst request to the network;

receiving at least one time value for at least one talk burst control timer from the network after the terminal sends the talk burst request and when the at least one time value requires updating by the network;

updating a management object of a device management client in the terminal with the at least one time value; and

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

wherein the receiving step comprises

receiving a session initiation protocol (SIP) message, sent from the network to the terminal, the SIP message containing the at least one time value that is used to update at least one talk burst request timer of the terminal, whereby the SIP message is a response message responding to a SIP invite message sent from the terminal to the network during a process of establishing a session between the network and the terminal;

or

wherein the receiving step comprises

receiving a real-time transport control protocol (RTCP) message, sent from the network to the terminal after a session is established therebetween, the RTCP message containing the at least one time value that is used to update at least one talk burst request timer of the terminal, whereby the RTCP message is a talk burst control protocol (TBCP) message.

2. The method of claim 1, wherein the at least one time value is received periodically or at certain times.

3. The method of claim 1, wherein the at least one talk burst control timer comprises at least one of a talk burst release timer, a talk burst request timer, or an end of real-time transport protocol (RTP) media timer, and wherein the at least one talk burst control timer further comprises at least one of a push-to (PT) client retry-after timer and a talk session BYE timer.

4. The method of claim 1, wherein the at least one time value is received via device management (DM) provisioning method.

5. The method of claim 1, wherein the steps are performed for a push-to talk over cellular (PoC) service.
