  1. Emergency call number support Authors: Date: 2007-09-18 Notice:This document has been prepared to assist IEEE 802.11. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

  2. Abstract Emergency call numbers are necessary when a user makes an emergency call. It is impossible a terminal to store all the emergency call numbers of each network. Therefore network should provide these numbers. Currently, 11u draft v1.0 does not support that STAs can obtain emergency numbers from network. We propose a method to provide emergency call numbers to STAs by adding information to GAS protocol. Elly (Eunkyo) Kim

  3. Whenever a user makes an emergency call, emergency call numbers are needed. Emergency call numbers of each SSPN are different. There are many emergency call numbers around the world. Almost 220 countries use 400 emergency call numbers or so http://www.sccfd.org/travel.html If not provided by network, STAs should store all the emergency call numbers of each SSPN.  overhead! Discussion Elly (Eunkyo) Kim

  4. Discussion (cont’d) • In the United States dialing 911 on their telephone is the fastest way they can get help in an emergency. • What happened if they travel to Australia?? • No one wants to spend time looking up the phone number. Elly (Eunkyo) Kim

  5. Discussion (cont’d) • In 3GPP IMS call, the network may provide a capability to enable a terminal to obtain local emergency numbers. • This was already debated (07/0033r1) • TS 23.167 – IP Multimedia Subsystem (IMS) emergency sessions • Defines the stage-2 service description for emergency services in IMS, including the elements necessary to support IP Multimedia emergency services • This document covers also the Access Network aspects that are crucial for the provisioning of IMS emergency services including fixed broadband access aspects, GPRS and 3GPP/WLAN Interworking. • TS 24.008 – a procedure to provide local emergency numbers for UMTS and GPRS access • By sending the Emergency Number List IE when a UE moves to a VPLMN where its emergency numbers could be changed • LOCATION UPDATING ACCEPT messages • ATTACH ACCEPT messages • ROUTING AREA UPDATING ACCEPT messages Elly (Eunkyo) Kim

  6. Proposal Emergency call number support by GAS protocol!!! • Adding a new Native Query Info ID, Emergency Call Numbers • STAs can obtain its local emergency call numbers by GAS native query protocol Current Native Query Info ID definitions Proposed Native Query Info ID definitions Elly (Eunkyo) Kim

  7. Proposal (cont’d) Emergency call number support by GAS protocol!!! • Adding a new Native Info Element, Emergency Call Number List element • Can be contained in GAS Response Elly (Eunkyo) Kim

  8. indicating Emergency Call Number Proposal (cont’d) Emergency call number support by GAS protocol!!! Elly (Eunkyo) Kim

  9. Motion • Move to includenormative text in 11-07-2412-00-000u-normative-text-emergency-call-number-support changes to the 802.11u into the TGu draft. Mover: Seconder: Elly (Eunkyo) Kim
