Abstract: A telecommunication system and method for notifying a calling party, via a Preventive Disturbance Announcement (PDA), that a called party is in an area where the called party would prefer not to be disturbed with non-urgent calls. The calling party is then given the opportunity to either talk to the mobile called party or to leave a message or callback number. If the calling party decides to try to talk to the user, a Home Location Register (HLR) directs the call to a Visitor Location Register (VLR), and a mobile ending call is generated via a Mobile Switching Center (MSC). For non-urgent calls, the called party is given an option to refuse a voice mail page or Caller ID page of the non-urgent calls. The HLR will direct the Short Message Service (SMS) Service Center (SMS/SC) to store, in a buffer or external source, the Caller ID of non-urgent calls that were not connected to the called party while the PDA was active.
