3GPP TSG SA WG2 Meeting #74 S2-094882 06 – 10 July, 2009, Sophia Antipolis, France Title: Interim Comments on IETF PhoneBCP Draft Source: 3GPP TSG SA WG2 To: Hannes Tschofenig (Hannes.Tschofenig@gmx.net), Chairman IETF Ecrit Marc Linsner (marc.linsner@cisco.com), Chairman IETF Ecrit Cullen Jennings (fluffy@cisco.com), IETF Real-time Applications and Infrastructure Area Director Cc: IETF Ecrit Working Group 3GPP TSG CT WG1 Contact Person: Name: Stephen Edge Tel. Number: +1-858-651-6234 E-mail Address: sedge@qualcomm.com Attachments: none 1. Overall Description: 3GPP TSG SA WG2 along with 3GPP TSG CT WG1 were requested by the TSG CT Chair on behalf of IETF Ecrit on May 6 to provide any feedback on the issue of applicability of the phoneBCP draft to a cellular environment. The immediate issue at the time was inclusion of an applicability statement in the draft but we assume that the question of applicability itself would also be of concern. The Email request was as follows: From: Hannu Hietalahti [mailto:hannu.hietalahti@NOKIA.COM] Sent: Wednesday, May 06, 2009 4:48 AM To: 3GPP_TSG_SA_WG2@LIST.ETSI.ORG Subject: Question on draft-ietf-ecrit-phonebcp Dear CT1, SA2, in the 3GPP - IETF telco earlier this week a question was brought up on whether the phonebcp IETF draft could be applicable on cellular systems or not: http://www.ietf.org/internet-drafts/draft-ietf-ecrit-phonebcp-09.txt We have got no dependency from 3GPP specifications and I am not saying that we should have. In the 3GPP - IETF telco I promised to ping the 3GPP groups working in the area of VoIP and emergency calls just in case someone might be able to help in this question. The question seems to be whether it would be justified or not to restrict the applicability area of the draft by excluding the use of it in cellular environment. Even if we are currenlty not directly referencing to the draft, for me it sounds a bit odd if IETF needs to start categorising SIP extensions to those that are applicable in cellular environment and to those that are not. If you think you can help to solve this, please keep the CC'd Cullen Jennings and Hannes Tschofenig in the discussion. BR, Hannu Hietalahti 3GPP TSG CT Chairman tel: +358 40 5021724 Up to this point, there have been no comments on the SA WG2 Email reflector and no meeting contributions on this issue. But the work items within SA WG2 that could normally address comments related to this and to which any contributions might have been directed are not on the agenda in this SA WG2 meeting and hence a definitive response is not possible at this time. However, the subject areas are back on the agenda in our next meeting on August 31 to September 4. We therefore plan to provide a definitive response to IETF Ecrit from our next meeting and hope that this may be of use in completing this draft. 2. Actions: None 3.
