ETSI在其技术标准政策中让步于美国

美国的几家大计算机公司看起来已经赢得它同欧洲电信标准机构(ETSI)的一场争执。引发这场争执的原因是ETSI计划对这些公司的一些专利技术实行强制许可。去年九月初公布的投票表决结果表明,ETSI88.4％的成员要求ETSI放弃这个计划。 设在华盛顿的计算机及商用机器制造商协会在去年指控ETSI的知识产权政策违反了欧洲联盟的竞争

Hiperlan/2 Public Access Interworking with 3G Cellular Systems

This paper discusses some of the recent work within the Broadband Radio Access Network (BRAN) project of ETSI (European Telecommunications Standards Institute), regarding the issue of establishing an interworking solution between Hiperlan/2 and 3G cellular systems and introduces the concept of Hiperlan/2 Public Access. So far the BRAN project has identified several fundamentally different types of possible solutions whose differences lie within the level of integration. The most essential requirements identified were authentication, mobility between Hiperlan/2 and 3G, service continuity, and preservation of the applied security levels. Recent agreements between ETSI, IEEE and MMAC may now take this work forward to produce a generic WLAN to 3G and external networks interworking standard. Indeed such work may also form the precursor for post 3G systems.     

A report on HIPERLAN standardization

HIPERLAN is the new European standard for radio LANs currently being formulated by ETSI RES10 for operation at 5 GHz and 17 GHz. It will be suitable for radio replacement of wired LANs and for ad hoc networking providing a user data rate of 10–20 Mbit/s. This paper is a review of the work of ETSI RES10 on the formulation of the HIPERLAN standard. The origins of ETSI RES10 are documented. The targets set for HIPERLAN and the problems in achieving these targets are discussed. The paper reviews the technical arguments for and against the proposed solutions to these problems, concentrating on the design of the transmission scheme and the channel access mechanism. The discussions leading to significant decisions about the standard are summarized. If the FCC in the United States of America allocate the equivalent 5 GHz band to unlicensed wireless LAN systems, many of these discussions will be revisited for future standards in this band. The paper will be of interest to anyone in academia or industry wishing to be brought quickly up to date with the state of the standard in order to focus their research or development activities. The paper also gives a general insight into the technical side of the standards formulation process in ETSI.     

Overview of IN and TMN harmonization

Introduces the work being performed in ETSI and ITU-T on the management of IN and on IN and TMN harmonization. After a short history of, and rationale for the work in this area, a brief overview of the results achieved in ETSI's joint experts group on IN/TMN is provided. This includes the proposed mapping of the IN functional entities onto TMN function blocks and the proposal for integration of IN and TMN modeling techniques. This work has resulted in the “Baseline Document on the Integration of IN and TMN”. Both ETSI and ITU-T have accepted this document as a starting point for further addressing the special requirements of IN with respect to management (i.e., rapid deployment and provisioning of new services and corresponding management functionality). The work on further alignment of IN and TMN terminology and concepts is an ongoing activity, as both IN and TMN concepts are expected to evolve toward the definition of open and distributed platform-oriented environments. The article also addresses this work program, the intermediate results, and the expected outcome of this continued effort on the standardization of IN management

Toward Wireless Multimedia Communications. Current Standards and Future Directions

There are two major trends in communicationstechnology: multimedia and mobile communications. Thisis necessary to support new service concepts anddemanding capabilities of wireless communicationsystems. Although the migration to ATM-based broadbandISDN is visible, wireless ATM (WATM) internetworking formobile clients is still in its infancy. In this article,a brief overview of the current mobile communications standards GSM and DECT is presented. It isshown why these standards fail to deliver adequateperformance for multimedia data transfer. We thendescribe the recently approved IEEE 802.11 wirelesslocal area network standards and ETSI HIPERLAN 1 indetail and discuss their suitability for the transfer ofATM cells. Next, the ongoing work of the ATM Forum'sWATM Working Group and the efforts of the ETSI RES 10 regarding the further development ofHIPERLAN 2, 3, and 4 is elaborated. Finally, severalexisting WATMs are described.     

Reconciling the ETSI coverage requirements for DVB-T with the ITU-R recommendations

Digital Video Broadcasting Terrestrial (DVB-T) is a standard issued by the European Telecommunications Standards Institute (ETSI). The ETSI also issued some implementation guidelines regarding transmission aspects which include coverage requirements. For broadcasting designers, the main reference for calculating coverage is the recommendations of the International Telecommunication Union—Radiocommunication Sector (ITU-R). However, we are in trouble if we try to use the ITU-R recommendations to meet the ETSI coverage requirements because the latter specify a minimum signal level at the receiver to be guaranteed over 99 % of time whereas the ITU-R recommendations only give a calculation procedure for up to 50 % of the time. The present paper offers a method in order to adapt the ETSI coverage requirements to the ITU-R recommendations, based on a research measurement of the DVB-T signal level received in four different environments over a long period of time.
