ABSTRACT:
A method for invoking a silent mode for a Push-to-talk technology (“PTT”) mobile terminals. When a mobile terminal user selects the silent mode option, the mobile terminal sends a message to a PTT server that maintains a PTT user accept list. This message instructs the PTT server to disable a global setting that controls the PTT accept list. Once disabled, all incoming PTT calls are in manual answer mode and require user interaction to be accepted. The calling party is notified that the called party is not in auto-answer mode and that the PTT invitation must be accepted before a PTT call session can occur. When exiting silent mode, the user again selects the silent mode option. This causes the mobile terminal to send a message to the PTT server instructing the PTT server to enable the global setting that controls the accept list, thereby enabling auto-answer mode.
