  ITU-T A.5 justification information for referenced document ETSI TS 124 229 V13.3.1 (2016-01) in draft G.1028
1. Clear description of the referenced document:
Name: ETSI TS 124 229 V13.3.1 (2016-01)
Title: IP multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3 (3GPP TS 24.229 Release 13)
2. Status of approval:
3GPP TS 24.229 V13.3.1 (2015) approved on 2015-09-25
3. Justification for the specific reference:
Explains the concept of SIP preconditions (optional for VoLTE, but often implemented) and how they are used in practice. SIP Preconditions have an impact on call success rate and post dialing delay.
4. Current information, if any, about IPR issues:
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http://ipr.etsi.org). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document.
5. Other useful information describing the "Quality" of the document:
Approved Standard
6. The degree of stability or maturity of the document:
Approved Standard
7. Relationship with other existing or emerging documents:
None
