发明名称 Calling party ringtone selection in telephone system
摘要 A ring tone service is provided to a called party upon receiving a call from a calling party at a device of the called party, where the device annunciates the call according to a particular ring tone as determined by the called party. A network-based call control manager receives a notification that the calling party is calling the called party, and the call control manager queries a network-based ring tone manager to determine the particular ring tone. The ring tone manager notifies the call control manager of the determined ring tone, and the call control manager sets up the call to be annunciated at the device of the called party according to the determined ring tone.
