1 3GPP2 IP Based Emergency Calls IETF/3GPP Hosted SDO Emergency Services Coordination Workshop Columbia University, New York 5-6 October, 2006 Deb Barclay Lucent Technologies +1.630.690.2058 DLBarclay@lucent.com
5 Oct. 2006 3 Introduction The Third Generation Partnership Project 2 (3GPP2) is: A collaborative third generation (3G) telecommunications specifications-setting project Comprised of interests from the Americas and Asia developing global specifications for MAP “Wireless Radiotelecommunication Intersystem Operations” network evolution to 3G Focused on global specifications for the radio transmission technologies (RTTs) supported by MAP and the wireless IP core networks, together known as the cdma2000 ® family of standards.
5 Oct. 2006 4 Background –3GPP2's specifications are developed within in the Project's four Technical Specification Groups (TSGs) comprised of representatives from the Project's Individual Member companies. The TSGs are: TSG-A (Access Network Interfaces) TSG-C (cdma2000 ® Air Interface) TSG-S (Services and Systems Aspects) TSG-X (Core Networks) –All TSGs report to the Project's Steering Committee, which manages the overall work process and adopts the technical specifications forwarded by the TSGs. –website: www.3gpp2.org
5 Oct. 2006 5 Organizational Partners (OPs) ARIBAssociation of Radio Industries and Businesses (Japan) CCSAChina Communications Standard Association (China) TIATelecommunications Industry Association (NAFTA countries: USA, Canada, Mexico) TTATelecommunications Technology Association (Korea) TTCTelecommunication Technology Committee (Japan)
5 Oct. 2006 6 Other 3GPP2 Partners –Market Representation Partners (MRPs) –CDMA Development Group –IPv6 Forum –IA450 Association –MobileIGNITE –Observers –ETSI –TSACC –ITU –Individual Members: More than 80 companies
5 Oct. 2006 7 Other Collaborative Efforts –3GPP - 3GPP2 IMS Core Network specifications based on 3GPP –IETF - base specifications on RFCs. When additions are needed, prefer to work with IETF rather than define solution/extensions unique to 3GPP2 –OMA - coordination with OMA regarding location and other services –TIA - offered to support 3GPP2 if needed, or if any USA/regional specific requirements need to be specified outside 3GPP2 –Liaison letters regarding Next Generation Emergency Services recently received from NENA i3, NENA location and ATIS-ESIF-NGES.
5 Oct. 2006 8 IP Based Emergency Services –Requirements: Stage 1 S.R0115 “All IP-Network Emergency Call Support” - Stage 1 requirements, produced by TSG-S; recommended for publication on Sept. 14, 2006 – Will be available on the 3GPP2 website, under the “Specifications” tab. –Architecture/Protocol: Stage 2/Stage 3 Core network impacts will be developed in TSG-X (e.g., MMD) Access network impacts will be developed TSG-A and TSG-C (e.g., cdma2000 air interface)
5 Oct. 2006 9 S.R0115 Requirements –Supports Voice over packet (WLAN or cdma2000) emergency call originations to legacy emergency centers (e.g., PSTN capable emergency call centers). –3GPP2 can not have country specific requirements, but does have optional functionality to meet the needs of local regulation. –The All-IP Network will indicate to endpoint if emergency calls are supported –Endpoint should indicate emergency call. If not, the All-IP Network will detect local emergency numbers. –Support for local emergency numbers and addresses (TEL URI, SIP URI) –Endpoint will include positioning information in the emergency call request, which may be cell/sector, geoposition, or civic location. –Knowledge of emergency call is end to end when necessary, including intermediate points.
5 Oct. 2006 10 S.R0115 Requirements –Routing to a emergency call center based on the caller’s location and the required type of emergency call center (e.g. fire, police, ambulance etc.) Routing may be based on rough initial location or accurate location –Emergency call supported in home and roaming scenarios. Roaming scenarios may be routed from visited network –Only authorized endpoints are supported (implies home network subscription and roaming agreements) –Updated position requests from emergency call center will be supported –Callback of authorized emergency callers supported –Call will be maintained even after handoffs between access technologies –Accurate updated caller location following a handoff provided when requested by the emergency call center –Service interactions that put call on hold are not allowed –Call Detail Records supported
5 Oct. 2006 11 S.R0115 Future Considerations –Emergency Calls to IP emergency call centers –Support for emergency calls with other media types: e.g., text messaging, pictures, video –Calls from unauthorized endpoints (e.g., no UIM)
5 Oct. 2006 12 Stage 2 Expectations –Will build on existing All-IP architecture and 3GPP2 protocols – MMD (IMS), cdma2000 air interface, WLAN, Location Service –Impact to MMD, cdma2000 air interface, WLAN, Location Services can be expected –New servers likely to be added to the serving network – e.g. specialized SIP server (CSCF or AS) for emergency calls, separate location and routing server(s) –Reference to or inclusion of IETF and NENA capabilities (e.g. Geopriv pidf-lo, NENA i2)
5 Oct. 2006 13 Challenges –All IP-Network architecture and signaling protocols are different than traditional wireless voice network so geopositioning for IP emergency calls can not be assumed –IP Access Which combinations should be supported for emergency calls? – Fixed IP versus Mobile IP (MIP) – For MIP, Home Agent in the home network or allowed in the visited network – IPv4 versus IPv6 When roamers with an established IP connection to home network originate an emergency call, can current configuration be used or re-establish packet connection to visited network?
5 Oct. 2006 14 Challenges –Call establishment exclusively via the visited network versus via the home network (and visited network) –Handoff of emergency calls –Location updates after a handoff
5 Oct. 2006 15 Summary –3GPP2 faces many of the same challenges as identified by other organizations and this workshop –3GPP2 would like to work cooperatively with other groups to achieve global solutions. –Thank you!
