Abstract

This document describes the standardization collaboration between
3GPP2 and IETF.

1. Conventions used in this document

This document uses significant terminology that is specialized to
IETF, 3GPP2, 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 3GPP2 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 3GPP2 use of IETF Internet Standards

In the further development of 3GPP2 specifications, the benefit of
adopting Internet specifications has been identified.

The preferred 3GPP2 approach is to use the Internet standards
unchanged, if feasible. In any case, 3GPP2 has no intention to
duplicate work performed in IETF.

However, while this document recognizes the importance of 3GPP2
interoperability with the existing Internet and hence the use of IETF
standards, 3GPP2 recognizes that additions or modifications might be
needed in order to make the IETF internet specification fulfill the
needs of 3GPP2. In such cases, 3GPP2 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 3GPP2 Wireless eXPertise

The technical work in 3GPP2 is organized in Technical Specification
Groups TSGs each with their area of responsibilities. TSG-A and
TSG-C are responsible for the Radio Access networks based on CDMA and
thus the experts in the areas of the characteristics of the physical
transport. TSG-N is responsible for the Mobility Management and
other core network protocol and functionalities. TSG-P is
responsible for data services and applications. TSG-S 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 3GPP2 web-site www.3gpp2.org.

4. Document Sharing

Both 3GPP2 and IETF encourage the sharing of draft documents that are
of mutual interest.

3GPP2 working documents are available on its official web-site, and
are grouped according to the meeting. These documents can be found
on the 3GPP2 FTP server, which is open to anyone, at
ftp://ftp.3gpp2.org. 3GPP2 specifications, those that have completed
the 15-day Steering Committee review, can be found at:

http://www.3gpp2.org/Public_Html/Specs/index.cfm

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 3GPP2 document
and web-site structures by contacting the relevant 3GPP2 contact
points indicated at the 3GPP2 web-site (www.3gpp2.org).

3GPP2 representatives can obtain information about the IETF document
and web-site structures by contacting the relevant IETF contact
points, which are the Area Directors indicated at the IETF web-site
(www.ietf.org).

5. Communication

Whenever possible, informal communication at working level is
encouraged.

The vast majority of the technical discussions and decision making at
IETF is done over mailing lists. It is recommended that interested
individuals subscribe to and participate in these lists.

3GPP2 mailing lists, however, are not open to the general public. It
is recommended that work of mutual interest be discussed on the
relevant IETF mailing lists.

When deemed necessary, formal communication between 3GPP2 and IETF is
also permitted. Relevant IETF Area Directors and 3GPP2 technical
leadership are encouraged and authorized to facilitate such
communications when needed.

6. Rapporteurs/coordinators

6.1 IETF coordination support in 3GPP2

An IETF rapporteur function is established in 3GPP2 Steering
Committee.

The individual(s) appointed to undertake the responsibility of this
function should be the initial contact point in 3GPP2 for matters
pertaining to the 3GPP2-IETF cooperation. Of course, the chairman of
Steering Committee can always be contacted.

The 3GPP2-IETF rapporteur function, therefore, is expected to work
with the concerned working groups and TSGs and support the
interaction between 3GPP2 and IETF.

6.2 3GPP2 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 of a specific person in IESG to function as a "3GPP2
liaison" is proposed.

The role of the 3GPP2 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
3GPP2 meetings or participation in 3GPP2 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.

7. Participation

In order to assist the information flow between the organizations,
IETF can on a per case basis appoint an observer to participate and
represent IETF at 3GPP2 technical meetings.

IETF meetings are open to any interested individuals.

3GPP2 partners (OPs, MRPs) or individual members can participate in
any of the IETF meetings, in accordance with the existing IETF
procedures.

3GPP2 meetings are also open to any interested individual, however
such individuals do not have voting privileges. The meeting schedule
can be found on the 3GPP2 web site.

8. Security Considerations

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