Parlay Emergency Telecommunications Service (ETS) Working Group Charter

1. Parlay Emergency Telecommunications Service (ETS)Working Group Charter Ravi Jain rjain@telcordia.com

2. Proposed WG activities 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

3. Objective • 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

4. Goals • Develop requirementsand contributionsto 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

5. Deliverables • 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 • Detailed ETS Requirements for Call Control • ETS Contribution to Call Control WG • Detailed ETS Requirements for User Interaction • ETS Contribution to User Interaction WG • Additional deliverables to be defined in further phases

6. WG Discussion: 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

7. WG Discussion: 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

8. Challenges • 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

9. Logistics • Meet the deadline for the Parlay 4.0 (2Q02) Spec Release • Meetings • 3 Working Group meetings/year • Conference Calls as and when needed • Web Page, Email List and Email Exploder • Initial page and list already set up • Web site: http://www.argreenhouse.com/ngnets/ • Email exploder set up • Formation • Interest, commitment and sufficient number of participating member companies to ensure completion of deliverables

10. Dates for Deliverables • Dec 2001: • Draft White Paper (including sample scenarios) on ETS and Ongoing ETS Standardization Activities (ITU-T, IETF etc.) • Jan 2002: • Final White Paper on ETS and Ongoing ETS Standardization Activities (ITU-T, IETF etc.) • Draft Detailed Requirements ETS in Call Control • Feb 2002: • Final Detailed Requirements for ETS in Call Control • Contribution to Call Control WG for Hong Kong meting • Mar 2002: • Draft Requirements for User Interaction • Apr 2002: • Final Requirements for User Interaction • Contribution to User Interaction WG • May 2002: • Revised contributions to CC/UI in preparation for P4.0 release
