Re: CDG & 3GPP
Long - Detailed - Boring
<< A cursory site search provided no details on 3GPP admission procedure. Do you know if the process involves a majority vote, or is "unanimity" amongst MRP's required? >>
It appears not ... and as a matter of fact ...
... the 5 page 3GPP "Agreement" (which a new MRP must sign) states "Any additional Partnership in 3GPP shall be approved on a consensus basis, by the existing Organizational Partners"
3gpp.org
[ the agreement does not refer to approval by an existing MRP, so my original comment appears to be in error. Drat. Wrong again <g> It is easy to misread this stuff ]
Regardless, I would think that all MRP's need to be very comfortable with a decision of this type.
This is a massive collaborative global initiative, and it amazes me how successful it has been to date.
Here is what (I think) I know. I won't guarantee that everything I say is gospel.
If anyone can add clarity (or accuracy) please do so.
3GPP Background
The "Third Generation Partnership Project" known by the acronym "3GPP" was created in early December 1998 by five "globally recognized market driven Standards Development Organizations" (OP's):
* ARIB (Japan)
* ETSI (Europe)
* T1 (USA)
* TTA (Korea)
* TTC (Japan)
>> The Partners agreed to co-operate in the production of globally applicable Technical Specifications and Technical Reports for a 3rd Generation Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes).
The Partners have further agreed to co-operate in the maintenance and development of the Global System for Mobile communication (GSM) Technical Specifications and Technical Reports including evolved radio access technologies (e.g. General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution {EDGE}). <<
* CWTS (China) joined 3G as an OP in May 1999.
* TSACC (Canada) participates in 3GPP as an Observer, as does TIA (USA).
The original four Market Representations Partners joined 3GPP in this order:
* GSM Association (GSMA fka GSM MoU)
* Global Mobile Suppliers Association (GSA)
* UMTS Forum
* Universal Wireless Communications Consortium (UWCC).
New Market Representations Partners are:
* IPv6 Forum
* MWIF
* 3G.IP
In June 1999, 3GPP compromised on "chip rate" with CDG and 3GPP2.
Cease Fire. Holy Wars Over. Harmonization Commences.
Three modes of CDMA operation were agreed to (3G3).
The Operators Harmonization Group (OHG) was established.
3GPP published UMTS 'Release 99' in November 1999, made final changes in March and the document was accepted by the ITU in April 2000.
UMTS 'Release 2000' was in progress. It was cancelled and is now divided into 'Release 4' and 'Release 5', due to be published in 2001. Focus is on an all IP Network.
3GPP2 Background
CDG wanted to join 3GPP (I believe).
CDG was denied admittance. I am not sure that they made formal application.
At least part of the reason for this (I believe) was that CDG (and QUALCOMM) were insistent (and persistent) that CDMA have a single converged third generation standard that would operate in both a GSM/MAP and ANSI-41 environment. They insisted that the standard be formulated around QUALCOMM's "5 Points":
127.0.0.1:3456/SI/stocktalk/readmsg.aspx?msgid=6207324
ETSI and 3GIG (predecessor to 3GPP2) had already decided on wideband CDMA (modified Ericsson/DoCoMo proposal) as the radio interface(s) of UMTS, and the first three of QUALCOMM's "5 Points" were not the way they wanted to approach wideband CDMA (although a chip rate "compromise" was reached 18 months later.
CDG formed 3GPP2 in late January 1999 to advance the cdma2000 standard on the evolved ANSI-41 core networks.
>> "Four globally recognized Standards Development Organizations (SDOs): ARIB (Japan), TIA (USA), TTA (Korea), and TTC (Japan) - the Organizational Partners - have agreed to cooperate in the preparation of globally applicable Technical Specifications for a 3rd Generation Mobile System based on the evolved ANSI-41 core networks, and the relevant radio access technologies to be transposed by standardization bodies into appropriate deliverables (e.g., standards). The partners currently refer to this activity as Third-Generation Partnership Project 2 (3GPP2) to distinguish it from other partnership projects. This group will develop global specifications to elaborate on one of the Radio Transmission Technologies (RTTs) submitted to the International Telecommunication Union (ITU) and called cdma2000." - 3GPP2 Press Release Excerpt - <<
3GPP2 has advanced the cdma2000 standard (now a mode of operation) and that standard is similar to QUALCOMM's "5 Points" except for "Principle 3" (SIM/R-UIM incorporation).
The IS-2000A (initial cdma2000) phased standard was published by TIA in July 1999. It was finalized in March, 2000 and approved (with changes and updates resulting from harmonization by the ITU in April 2000.
3GPP2 recently concluded standards work in 1xEV-DO and is now focused on completing 1xEV-DV, and having both new standards (as well as higher transmission speed for 1xRTT) published and accepted by the ITU as a 3G IMT-2000 standard.
ETSI now has "Observer" Status in 3GPP2.
CDG and 3GPP
In December 1999 CDG made application for MRP status in 3GPP.
They were asked to supply more detail regarding their "motive" for this request.
CDG provided more detail.
It was still felt, evidently, that CDG's support of W-CDMA technology was not particularly obvious (and of course W-CDMA is the standard 3GPP works on).
CDG was asked to provide yet more detail the relationship between CDG and W-CDMA technology. They complied, and included detail from their web site.
Although I can not verify it (find it), I believe I have seen (publicly available) correspondence that suggested that CDG consider making changes to their web site to properly demonstrate that they supported evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes), as well as cdmaOne and cdma2000 on an ANSI-41 Core.
In the spring of 2000 the W-CDMA logo first appeared on the CDG web site.
At a meeting of 3GPP2 (immediately following a 3GPP meeting) in Beijing, China in July, Adrian Scrase of ETSI (liaison to 3GPP2 and champion of CDG's admittance request), made a presentation to 3GPP2.
One of Adrian's slides commented on CDG's application to 3GPP and this is the text of that slide:
>> CDMA Development Group has changed its scope as follows:
"To lead the rapid evolution and deployment of CDMA-based systems, based on open standards and encompassing all core architectures, to meet the needs of markets around the world in an emerging, information-intensive environment"
Once the change process is complete CDG will be welcomed as an MRP in 3GPP <<
My interpretation of this slide was and is that CDG was asked to alter their focus (and public persona) to some degree and that they were in the process of compliance but were not yet completely in compliance.
Close but no banana.
<< Perhaps verbatim clarity regarding an earlier statement is material. From Nov.00 3GPP2 Steering Committee Meeting Summary: "The CDG application to become a 3GPP MRP is still pending." >>
Yes. This is where I think we are at.
The Operational Partners have evidently been appraised the CDG is in the process of changing its mission and scope and that this will be reflected within their technical activities.
The OP's understand that this is a significant change for CDG and that the change process may take some time, but are urging that these changes be expeditiously.
So far as I can tell ETSI is supportive. I would assume that the other SDO's are as well. Hopefully the MRP's they interact with are also comfortable.
Still pending!

That's about all I know (or think I know). <g>
Sorry for the delay. I thought I would check back on some detail before responding.
