[{"name":"S2-1900029","title":"LS from CT WG1: LS on emergency registration from states other than limited service state","source":"CT WG1","contact":"Marko Niemi","contact-id":16608,"tdoctype":"LS in","for":"Action","abstract":"CT WG1 noticed that in TS 23.501 the definition for 'Emergency Registered' is applicable only if the registration for emergency services is initiated when in limited service state. TS 23.501: 'Emergency Registered: A UE is considered Emergency Registered over an Access Type in a PLMN when in limited service state and registered for emergency services only over this Access Type in this PLMN.' CT WG1 would like to highlight that the initial registration for emergency services can be initiated also from states other than limited service state e.g. from 5GMM-DEREGISTERED.ATTEMPTING-REGISTRATION state. The UE enters to 5GMM-DEREGISTERED.ATTEMPTING-REGISTRATION state when normal initial registration to the PLMN is rejected due to general NAS level mobility management congestion control and MM back-off timer T3346 is started. In this state the UE camps normally in the cell (i.e. not in limited service) and normal cell reselection process applies. The normal initial registration procedure can be started when timer T3346 expires, but while the timer is running the UE is allowed to perform initial registration for emergency services. For the reasons above CT WG1 has agreed TS 24.501 CR#0435rev5 in Tdoc C1-188587 making correction to the definition of 'Registered for emergency services' removing its limitation to registration from limited service state only (please find the CR attached). Action: CT WG1 kindly asks SA WG2 to take above scenario into consideration, to give feedback if needed and to adjust requirements in TS 23.501 accordingly.","secretary_remarks":"Response drafted in S2-1900659.
