Proposed WG activities
www.parlay.org
1. Identify requirements for Parlay APIs to enable
priority services to authorized users during
emergency and congestion scenarios
– service scenarios
– specific requirements
2. Introduce contributions to other WGs that
suggest examples of how the requirements
could be satisfied
3. Provide Feedback into the Parlay UML model

Objective
www.parlay.org
• Identify requirements and introduce
contributions for Parlay APIs that enable
equipment manufacturers, network operators,
and service providers to develop and offer a
wide range of priority services to authorized
users that aid in a high probability of completion
for emergency traffic during a crisis situation
when networks may be restricted due to
damage, congestion or faults

Goals
www.parlay.org
• Develop requirements and contributions to
support ETS - e.g. the Parlay call control, policy
management, UI APIs - for multiple types of:
– communication (data, email, video, multimedia)
– networks (wireless, packet)
– technology (protocols, architectures)
• Address impact to Mobility, PAM, Charging and
Framework APIs (e.g. for location-based service,
accounting bypass, security, etc.)
• Achieve broad-based involvement across Parlay
member companies
– Several members have already expressed interest in
joining the ETS WG: Sun, SBC, SAIC, NCS, Ericsson
• Engage and coordinate ETS work with ITU-T,
IETF, 3GPP, MSF, JAIN, ETSI and other groups

• White Paper on ETS in the context of Parlay and
Next Generation Networks and Ongoing ETS
Standardization Activities (ITU-T, IETF etc.)
– Scope and direction
– Sample scenarios

ETS Overview
• ETS enables effective communication for
emergency operations during times of severe
network congestion due to man-made or natural
disasters
– Basic service includes priority access, user authentication,
and enhanced routing, exemption from Network
Management Controls
– Several countries already offer some emergency
telecommunications services:
• Canada: Line Load Control to deliver priority dialtone
• USA: GETS
• Japan: “I Am Alive” via web site registration

ETS Overview (continued)
• Need to extend A/IN-based and switch-based
priority services defined for ETS calls to Next
Generation networks and open APIs such as Parlay
• Background white papers etc:
http://www.iepscheme.net
– Vernon Mosley’s presentation to the Parlay group at San
Diego, 5/23/01
• See http://www.parlay.org
– See also IETF Drafts and Recommendation E106
• 3 Parlay ETS proposal presentations have been
made at San Diego and in Munich
• Simple example in Parlay: Enhancing
Calling_Party_Category parameter for call control
by new value

Challenges
www.parlay.org
• Minimizing changes to existing Parlay APIs while
ensuring ETS functionality is met:
– Keeping in mind backward compatibility
– Through introducing optional parameters
• Coordinating with the other Parlay working
groups: Two-way interaction required (e.g. with
Call Control working group)
• Collaboration process with ITU-T, IETF, 3GPP,
MSF, JAIN, ETSI
