6.6 Study on S8 Home Routing Architecture for VoLTE (FS_V8) Updates to solutions
TD S2 160445 (P-CR) Update to Solution 5. (Source: Intel, Nokia, NTT DOCOMO).
Abstract: Proposes an update of solution 5 to include the case of anonymous SIP INVITE for UEs not supporting GIBA.
Discussion and conclusion:
Revised in parallel sessions to TD S2 160679. Orange asked for clarification on the use of the anonymous SIP INVITE in step 13. Qualcomm commented that the regulatory requirements can be fulfilled with the available solutions but are not necessarily set as default behaviour in the specifications. T-Mobile commented that for Rel-14 we should not rely upon CS call for emergency call. The SA WG2 Chairman suggested using a reference to 23.163 for the emergency call procedures instead of adding description here. This was left for off-line discussion and revised in TD S2 160806 which was reviewed and approved.
TD S2 160139 (P-CR) Clarification to Solution #1: PCRF based VPLMN ID and Local Database based non UE detectable emergency session. (Source: Ericsson).
Abstract: This document includes a clarification for solution 1 to include PCRF as an impacted node.
