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

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

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
( and is open to anyone. IETF documents,
including preliminary working documents ('Internet Drafts') are
available on its web-site ( and various shadow

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

Rosenbrock, et al. Informational [Page 2]

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-site

5. Communication

Whenever possible, informal communication at working level is

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

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.

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

8. Security Considerations

This type of non-protocol document does not directly affect the
security of the Internet.
