Representative methods, apparatus and systems to adjust Do Not Disturb (DND) levels in a wireless transmit/receive unit (WTRU) are disclosed. One representative method includes determining, by the WTRU, that a user of the WTRU is participating or is going to participate in a meeting; obtaining, by the WTRU, organizational hierarchy information; determining a priority associated with one or more meeting participants based on the organizational hierarchy information; and adjusting, without user input, a DND level of the WTRU based on the determined priority.
