8、M) report was published by ETSI in 1996 and as a result a GMM Co-ordination Group (GMMCG) and GMM Architecture Framework Group (GMMAFG) were set up.The editorial process was handled by Specialist Task Force (STF) 131.This report from the GMMAFG was approved by the ETSI Board#18 (23-25 March 1999) an

9、d subsequently by the32nd ETSI General Assembly (22-23 April 1999).1.1 GMM AFG - the backgroundGMM AFG has been in existence since June 1997 and has held ten meetings up to February 1999. The decision toupdate the existing GMM Report was aimed at aiding understanding of the report and the manner in

10、which it could beapplied to existing and future scenarios. A companion document was felt to be the most appropriate publication.It was decided that the focus of this companion document would be on a user/service perspective, with the seamlessprovision of services as a main objective. The enterprise

11、model which had been developed within the GMM reportwould be retained, and due account would be taken of the fixed-mobile convergence (FMC) studies then beingundertaken in ETSI.The main work on the Companion Document started in July 1998 and has occupied five meetings of the GMM AFG(each 1 to 1 days

12、) plus several side meetings and one teleconference.Various member companies have supported the work (see figure 1), with the main contributions coming from BT,Ericsson, Italtel, Lucent, Marconi Communications, Nokia and Telia.Figure 1GMM AFG - the backgroundMain work on Companion Document started J

14、 was a very large compendium (approximately 120 pages) of relevant or potentially relevantinformation and source material. This was intended to be the basis of the Companion Document and was supplementedby a bibliography of well over 100 references. However, as management of these resources was prov

15、ing difficult astheir size grew, the GMM AFG decided to freeze the compendium as a “repository document“ and produce from it aslimmer, more concise and focussed version as the eventual Companion Document. That new draft permitted the GMMAFG to take a fresh look at the task, which led to a better ide

16、ntification of key “drivers“ for GMM and a more objectiveassessment of the GMM model.Even this has proved to be difficult to manage, as new facets of GMM were explored. It was concluded that the finaldeliverable to the General Assembly should be this presentation which embodies all the key messages

17、concerning theupdating of the ETSI GMM concepts. The other material, including the bibliography, has been collected in theCompanion Document SR 001 677 2.Figure 2GMM AFG - the results “Repository” document Bibliography (well over 100 references) “Final” Draft Companion Document This presentation (Co

19、nts and some material not easilyaccessible. Although all of that material has been valuable for the compilation of the Companion Document (in itsvarious forms), not all of is likely to be helpful for subsequent studies.As a result, a “select bibliography“ has been produced and the contents classifie

However, after a time it became possible to regain a focus that recognized t

22、he hard fact that standards are onlya tool for achieving business success.Standardization thus has to be put in the context of business dynamics, and many of these are not at all technical. Mostmarkets in the world (not just the telecommunications market) are being increasingly dominated by a small

23、number oflarge, global players, in many instances consortia of former market leaders. Economies of scale are now perceived asonly being realizable in markets, which have global dimensions - what place now for national, or even regional,standards?The telecommunications business is huge, and investmen

24、ts are enormous. Technical solutions have to be right, butpolitics, regulation, geography, culture, economics, all have a part to play in the market decision-making, and standards-oriented decision makers will do well to remember that!The high cost of standardization leads to inevitable questions: I

25、s this spending wisely applied? Can we be smarter still at spending on standardization?Introduction We looked at business / change drivers, andnot standards per se How does the “external” environment impactstandards making?

32、share-holder“ value - aspointed out in the original GMM report. These changes result in an environment of mega mergers so as to have a bigenough presence to compete globally.This is also leading towards a “Knowledge Based“ economy, where knowledge (IPRs) are leveraged to obtaincompetitive advantage.

33、Access to information - anytime, anywhere - is also becoming a key competitive factor and is again introducing acultural shift towards a “web based“ digital world.With WTO, harmonized EU market, TABD, NAFTA and other (regional / global) trade agreements, it is no longer arequirement to have national

34、 “champions“ to do trade; thus causing rationalization of the manufacturing base - it ismore cost effective to have one big efficient factory then several small ones in each country.These changes are not sector specific: the telecommunications sector also has to face the same challenges ofliberaliza

35、tion, (de)regulation, increased competition and so on.Figure 5Corporate Cultural Change Drivers Mega mergers (consolidation):- DB / Bankers Trust DaimlerChrysler BP / Amoco- Vodafone / AirTouch Astra / Zeneca Stora / Enso(1999 M however, are we creating a new “business“ of “certifiers“ (via the cert

There is a tremendous businessneed to have timely information to ensure “competitive edge“.2) However, Internet

39、 is not limited to “business applications“ - which have created secure Extranets and Intranets toallow their workers and suppliers to work together in a team to improve gross profit margins. There is also alarge residential market for web based e-commerce which is estimated to grow exponentially as

40、people purchasesuch diverse things as pizzas to books to cars over the net (and not forgetting the home banking). These willpresent an opportunity for standardization: standards for electronic signatures and business-related securecommunications in general.3) Within Europe - at least within the “Eur

41、o-zone“ - there is a need for harmonization of security and paymentsystems. Studies into standardized Information Systems have been running for many years, in the belief thatsuch standardization is imperative for global trading; however, this has led to question whether “standardizers“will be able t

42、o “deliver the goods“. If there is no specific initiative, then proprietary solution(s) will prevail in themarket-place - as is shown by the stock market value of “Internet“ stocks. This phenomenon will run counter tothe standardization efforts.Figure 11“Internet” - things are changing fast ! Import

46、nternet. This figure wasexpected to reach $1.3 trillion by the year 2003, representing 9.4% of corporate purchases in America.Companies such as BOC Gases, Harley-Davidson Inc., and Mobil Oil Corp., already make extensive use of the Internetfor business e-commerce, citing major savings in ordering co

47、sts and an almost total elimination of errors. Addedbenefits were claimed because of the automation of the entire ordering, shipping and stocking processes.The business-to-business activity already outstrips the more visible retailing of consumer products, such as books, CD-ROMs, computers and the l

48、ike on the Internet, and, as can be seen in the chart, will far exceed the consumer retailactivity in coming years.Figure 12Electronic commerce02004006008001000120014001998 1999 2000 2001 2002 2003Business tobusinessRetailSource: Forrester Research, Cambridge, MA, USA$ US billion USA only!22 - 23 Ap

They are still developing at thesame fast speed and can be expected to continue for foreseeable future.1) Digital wireless access technologies (not just radio) will work in co-operation with other access mechanisms,including cable modems, xDSL, ISDN and premises wiring (“smart“ house or office).
