| Abstract: | Disclosed is a method and apparatus for conserving power in a
telecommunications network during emergency situations. A permissible
number list of emergency and/or priority numbers is stored in the
telecommunications network. In the event of an emergency or power
failure, input digits of a call to the telecommunications network are
compared to the permissible number list. The call is processed in the
telecommunications network and routed to its destination if the input
digits match an entry in the permissible number list. The call is dropped
without any further processing if the input digits do not match an entry
in the permissible number list. Thus, power can be conserved in emergency
situations by only allowing emergency and/or priority calls. |
