Patent ID: 7813749

Claim:
A method of handling media data in a session based service of a wireless communications system having at least one or more client terminals and a server, the method comprising: receiving a control message from the server, the control message indicating that sending of a talk burst should be stopped, or indicating that the talk burst should be revoked or rejected; checking at least one reason code field included in the control message, wherein the reason code field has different values, each value corresponding to a unique reason, wherein the different values instruct the client terminal to discard remaining buffered media data or to transmit the remaining buffered media data to the server; and selectively processing the remaining buffered media data according to the checked reason code field, wherein the control message is received via a session that is established between the server and the client terminal, wherein the server and the client terminal support Session Initiated Protocol (SIP) techniques, and wherein the step of selectively processing includes: transmitting the remaining buffered media data to the server if the reason for the reason code field indicates that a user of the client terminal has talked too long or indicates that the talk burst is pre-empted, and discarding the remaining buffered media data if the reason for the reason code field indicates that only one user is in the session, or indicates that the client terminal does not have permission to send the talk burst.
