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

Vernon Mosley’s presentation to the Parlay group at San
Diego, 5/23/01

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
