APIs for Emergency Telecom Services (ETS)

The goal is to enable advanced and flexible ETS by allowing services to be developed using open, standard APIs rather than monolithic, stovepiped applications

Since the Parlay API is applicable to IP, wireless and PSTN any hooks introduced into the API apply to all networks

The Parlay API actually consists of a set of APIs for call control, mobility, user interaction, etc

Our first contribution is to put a hook into the call control API so that NGN calls or sessions can get High Probability of Completion– This extends the current capabilities possible in the PSTN to IP as

well as wireless networks

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

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, 3G 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 Recommendations E106, F706

3 Parlay ETS proposal presentations have been made at San Diego and in Munich

Parlay/3GPP OSA/ETSI SPAN 12 Architecture

The APIs encapsulate underlying protocols such as SIP or ISUP Applications are agnostic of underlying technology and thus highly portable

or/and can serve multiple networks (both IP, Mobile, and PSTN) There are Call Control APIs, Mobility, Presence, Policy, User Interaction, …

Essential network features for the successful operation of IEPS

Inspired by ITU-T Recommendation E.106 priority call origination priority call setup, including priority queuing schemes exemption from restrictive management controls, such as call

gapping

Inspired by ITU-T Draft F.706 extension of other APIs such as Multimedia Call Control,

Presence and Availability, Mobility (Location)

Standardization

Mid December, the Parlay Group approved the charter for the Parlay ETS Working Group

During the last Parlay meeting, February 5-7 in Hong Kong, the Parlay ETS Working Group held its first face-to-face

A contribution was submitted to Joint Working Group such that its APIs would support call marking– The contribution was accepted– Further contributions ETS enabling the Parlay APIs are in the

works! 3GPP SA1 does not have an ETS requirement yet (a study

group is working in this) An IETF working group is proposed, a third BoF discussing its

charter is on the agenda for IETF #53

1.) Requirementsintroduced by individual bodies

2.) create the APIthat supports the supersetof all requirements. (Joint meetings)

3.) Results are transferred back to individual bodies
