What is Emergency Telecom Service (ETS)?
Telecommunication services to
support emergency operations
Ensure effective communications to support
emergency operations through severely
congested and impaired resources during times
of man-made or natural disasters – e.g.
terrorism, earthquakes, hurricanes, etc
Authorized users – e.g. medical
services, fire brigades, police,
utilities, government and industry
recovery teams

Emergency Telecommunications Services (ETS)
 Need to extend A/IN-based and switch-based priority
services defined for ETS calls to NGN and open APIs
 Several countries have sponsored programs over the
past 15 years to ensure standards and
implementation programs for ETS
– Canada: Line Load Control to deliver priority dialtone
– USA: GETS
– Japan: “I Am Alive” via web site registration
 Details: http://www.iepscheme.net
– Vernon Mosley’s presentation to the Parlay group at San
Diego, 5/23/01
 See http://www.parlay.org
– Calling_Party_Category parameter for call control
– See also IETF Drafts and Recommendation E106 at

Impact of ETS on NGN APIs
 Need to handle new types of communication (data, email, video,
multimedia), new types of networks (wireless, packet) and
technology (protocols, architectures)
 These requirements impact Call Control and Policy
Management
 Also likely to impact Mobility, PAM, Charging and Framework
(e.g. for location-based service, accounting bypass, security,
etc.)
 Proposal: a focus group to generate initial requirements survey
and feed into Parlay 4 Requirements process and working
groups
 Web site: http://www.argreenhouse.com/ngnets
 Email exploder set up
