It does   not specify an Internet standard of any kind.  Distribution of this   memo is unlimited.Copyright Notice   Copyright (C) The Internet Society (2001).  All Rights Reserved.Abstract   This document describes the standardization collaboration between   3GPP and IETF.1. Conventions used in this document   This document uses significant terminology that is specialized to   IETF, 3GPP, or their areas of work.  SeeAppendix A for definitions   of acronyms.  The organizational definitions can be found in their   respective web-sites.2. Introduction   This document contains a set of principles and guidelines that serves   as the basis for establishing the collaboration between 3GPP and   IETF, with the objective of securing timely development of technical   specification that facilitate maximum interoperability with existing   (fixed and mobile) Internet systems, devices, and protocols.   Each organization will operate according to their own rules and   procedures including rules governing IPR policy, specification   elaboration, approval and maintenance.Rosenbrock, et al.

RFC 3113        3GPP-IETF Standardization Collaboration        June 20013. Reasons For Collaboration3.1 3GPP use of IETF Internet Standards   In the further development of 3GPP specifications, the benefit of   adopting Internet specifications has been identified.   The preferred 3GPP approach is to use the Internet standards   unchanged, if feasible.  In any case, 3GPP has no intention to   duplicate work performed in IETF.   However, while this document recognizes the importance of 3GPP   interoperability with the existing Internet and hence the use of IETF   standards, 3GPP recognizes that additions or modifications might be   needed in order to make the IETF internet specification fulfill the   needs of 3GPP.  In such cases, 3GPP will take its concerns directly   to the appropriate IETF working groups for resolution, or to an   appropriate Area Director if no appropriate working group can be   found.3.2 IETF access to 3GPP Wireless expertise   The technical work in 3GPP is organized in Technical Specification   Groups TSGs each with their area of responsibilities.  TSG-RAN and   TSG-GERAN are responsible for the Radio Access networks based on   UTRAN and GERAN and thus the experts in the areas of the   characteristics of the physical transport.  TSG CN is responsible for   the Mobility Management and other core network protocol and   functionalities.  TSG-T is responsible for Terminal aspects and   applications.  TSG-SA is responsible for the service and system   aspects including the overall architecture, security and O&M aspects.   Contacts for the TSGs can be found on the 3GPP web-sitehttp://www.3gpp.org/.4. Document Sharing   Both 3GPP and IETF encourage the sharing of draft documents that are   of mutual interest.   3GPP documents are available on its official web-site   (http://www.3gpp.org/) and is open to anyone.  IETF documents,   including preliminary working documents ("Internet Drafts") are   available on its web-site (http://www.ietf.org/) and various shadow   sites.   IETF representatives can obtain information about the 3GPP document   and web-site structures by contacting the relevant 3GPP contact   points indicated at the 3GPP web-sitehttp://www.3gpp.org/.Rosenbrock, et al.

RFC 3113        3GPP-IETF Standardization Collaboration        June 2001   3GPP representatives can obtain information about the IETF document   and web-site structures by contacting the relevant IETF contact   points (the Area Directors indicated at the IETF web-sitehttp://www.ietf.org/).5. Communication   Whenever possible, informal communication at working level is   encouraged.   The vast majority of the technical discussions and decision making in   both IETF and 3GPP is done over mailing lists.  Both 3GPP and IETF   web sites contain information concerning the associated mailing   lists.   It is recommended that interested individuals subscribe to and   participate in these lists.   When deemed necessary, formal communication between 3GPP and IETF is   also permitted.  Relevant IETF Area Directors and 3GPP technical   leadership are encouraged and authorized to facilitate such   communications when needed.6. Rapporteurs/coordinators6.1 IETF coordination support in 3GPP   An IETF rapporteur function is established in 3GPP TSG-SA.   The individual(s) appointed to undertake the responsibility of this   function should be the initial contact point in 3GPP for matters   pertaining to the 3GPP-IETF cooperation.  Of course, the chairman of   TSG-SA can always be contacted.   The 3GPP-IETF rapporteur function, therefore, is expected to work   with the concerned working groups and TSGs and support the   interaction between 3GPP and IETF.6.2 3GPP Liaison in IETF   The preferred way for organizations to work with IETF is through the   working groups.  However, IETF has a limited number of liaison   relationships with other organizations when conditions warrant the   appointment of a specific person.   The appointment, by the IAB, of a specific person to function as a   "3GPP liaison" is proposed.Rosenbrock, et al.           Informational                      [Page 3]

RFC 3113        3GPP-IETF Standardization Collaboration        June 2001   The role of the 3GPP Liaison is to act as an initial contact point in   IETF for administrative aspects of this collaboration that cannot   easily be handled in other ways (e.g., at a technical level by   interactions with IETF Working Groups or Area Directors).  It is   agreed that the role does not carry the expectation of attendance at   3GPP meetings or participation in 3GPP administrative processes and   anticipated that all liaison efforts assigned to this individual will   be carried out by electronic mail.  It is understood that the liaison   will not have the ability to make exceptions to, or special   provisions for, IETF policies and procedures.9. Participation   In order to assist the information flow between the organizations,   the IETF can on per case basis appoint a rapporteur to participate   and represent IETF at 3GPP technical meetings.   IETF meetings are open to any interested individuals.   3GPP partners (OPs, MRPs) or individual members can participate in   any of the IETF meetings, in accordance with the existing IETF   procedures.8. Security Considerations   This type of non-protocol document does not directly affect the   security of the Internet.Rosenbrock, et al.           Informational                      [Page 4]
