Federal regulators Wednesday approved a plan to create a nationwide emergency alert (警报) system
using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years, particularly among young people. The
wireless industry's trade association, CTIA, estimates (估计) more than 48 billions text messages are sent
each month.
The plan comes from the Warning Alter and Response Network Act, a 2006 federal law that requires
improvement to the nation's emergency alter system. The act tasked the Federal Communications
Commission (FCC) with coming up with new ways to alter the public about emergencies.
"The ability to deliver accurate and timely warning and alters through cell phone and other mobile services
is an important next step in our efforts to help ensure that the American public has the information they need
to take action to protect themselves and their families before, and during, disasters and other emergencies,"
FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alter system by carriers-telecommunication companies-is voluntary, but it has received
solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alters.
There would be three types of messages, according to the rules.
The first would be a national alter from the president, likely involving a terrorists attack or natural disaster.
The second would involve "approaching threats," which could include natural disasters like hurricanes or
storms or even university shootings. The third would be reserved for child abduction (绑架) emergencies,
or so-called Amber Alerts.
The service could be in place by 2010.
