[{"name":"S2-1904851","title":"LS from GSMA PACKET: on MME Functionality to Control Emergency Call Bearer Support Indicator","source":"GSMA PACKET","contact":"Maurice Pope","contact-id":648,"tdoctype":"LS in","for":"Action","abstract":"Background: As VoLTE advances and more operators are launching VoLTE roaming, becomes evident the need for requirements on emergency call such as the willing for VPMN to use IMS emergency call for their subscribers and for specific inbound roaming partners, as well as CSFB for other inbound roaming partners. GSMA NG Packet has agreed that 3GPP specifications allow multiple solutions to cover the above-mentioned requirements. However, operators observed, through testing, that many of those solutions (as outlined in the attached document) are not feasible, and GSMA NG Packet would like to see a unified solution that would work with all VoLTE devices. Only feasible solution seems to be the one which relies on EMC BS Indicator in MME, however, its usage appears to be implementation specific. Request to support selective emission of EMC BS flag by the MME based on Home network: In order to control the domain of emergency call per roaming partner, GSMA NG Packet kindly requests SA WG2 to support and implement the 'Emergency bearer service indicator' (EMC BS) by the MME per Home network (roaming partners) (from the earliest possible 3GPP Release). The following table describes different EMC BS configuration options in order to support different emergency call cases for both VPMN's own users and for inbound roamers.","secretary_remarks":"Postponed S2-1902943 from S2#132.
