ETSI TS 123 167

ETSI TS 123 167 defines the stage 2 service description for emergency services in the IP Multimedia Core NetworkSubsystem (IMS), including the elements necessary to support IP Multimedia (IM) emergency services.ITU-T Recommendation I.130 [4] describes a three-stage method for characterisation of telecommunication services,and ITU-T Recommendation Q.65 [3] defines stage 2 of the method.

This document covers also the Access Network aspects that are crucial for the provisioning of IMS emergency services.Other 3GPP specifications that are related to the IMS emergency services are TS 23.228 [1] on IMS in general,including fixed broadband access aspects, TS 23.060 [2] describing GPRS (UTRAN), TS 23.401 [28] describing EPS(UTRAN and E-UTRAN); TS 23.402 [29] describing Non 3GPP access (WLAN) to EPC; TS 23.271 [5] that coverslocation services and TS 23.216 [31] and TS 23.237 [32] describing Single Radio Voice Call Continuity for IMSEmergency session. TS 25.301 [6] contains an overall description of the UMTS Terrestrial Radio Access Network;TS 36.300 [30] contains an overall description of the Evolved Universal Terrestrial Radio Access (E-UTRA) andEvolved Universal Terrestrial Radio Access Network (E-UTRAN). Other non-3GPP specifications that are related tothe IMS emergency services include 3GPP2 cdma2000 HRPD IP-CAN, as specified in 3GPP2 X.S0060 [25] when theUE is connected to a PDS core network and 3GPP2 X.S0057-A [39] when the UE is connected to an EPC core network.

The emergency support in different IP-CANs is described in the Informative Annex E.
