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.  See Appendix 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.

3. Reasons For Collaboration

3.1 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-site
  http://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-site http://www.3gpp.org/.

  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-site
  http://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/coordinators

6.1 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.

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.
