3GPP-IETF Standardization Collaboration

Status of this Memo

This memo provides information for the Internet community. It does

not specify an Internet standard of any kind. Distribution of this

memo is unlimited.

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.

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.
