Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level 2-5 20 pt © Ericsson AB 20062006-09-293 3GPP specifications  IMS emergency is a Rel-7 work item –Foreseen freezing early 2007  Service requirements are specified in 3GPP TS 22.101 –This presentation is an overview of IMS emergency call requirements in 22.101 –The service requirements TS is already frozen (i.e. the functionality is there) –...but corrections and alignments are still possible  Architecture is specified in 3GPP TS 23.167 –The TS is under version control, but new features are still possible  Protocol details are in 3GPP TS 24.229 –Work in progress
