Foreword This ETSI Guide (EG) h
23、as been produced by ETSI User Group (USER). The interoperability issue stems to standardization being achieved by experts from manufacturers, operators and service providers who certainly have the users requirements in background but are mainly led by their own aims. In addition, the implementation
24、of most standards is voluntary and therefore areas of interoperability failure can result of lack of implementation. An example of this is the lack of affordable terminal facilities for disabled and elderly people. Nevertheless, the present document highlights also that users can not get the full in
25、teroperability they expect at the application level without coming to an agreement on the format of the information they want to exchange. Moreover, taking into account the fast evolution of the technology and IT world, it is anticipated that standardization should become a more flexible and living
26、area at least at terminal, service and application level. Introduction Standardization developed first in the telecom systems operated by the incumbent operators gaining progressively layers closer to the end-users. Industry needs standards and interoperability because markets need critical mass. Us
27、ers need interoperability because they want to take advantage of the competition so as to be able to access any service via any network using devices from different manufacturers. In the late 90s, competition between operators brought down the profitability of basic standardized systems. Since profi
28、ts no longer come from the backbone networks, operators certainly look for lower prices for standard equipment but develop competitive advantage in non-standard services. To keep its profitability, industry needs larger and larger markets. Today, the implementation of most ETSI standards is voluntar
29、y. ETSI “post crisis“ strategy is pushing towards standardization of enhanced customer care and after sales services. ETSI can not reach that goal without users inputs (including from disabled and older people), especially on the subject of interoperability. ETSI ETSI EG 202 308 V1.2.1 (2005-05) 6 1
30、 Scope In the current fast evolving telecommunications world, where various technologies are competing, interoperability is more than ever a fundamental feature that users expect from standardization and every effort is required to ensure it across networks and services. Despite significant standard
31、ization efforts, the user experience has shown in several occasions that interoperability is not provided end-to-end as anticipated. It is important to notice that any interoperability failure in a public service area might jeopardize a persons safety and even possibly his life. Therefore it is cruc
32、ial that interoperability is ensured in this field as widely as possible and that conditions, if any, where the service is not provided, are made clear to everybody. Nevertheless users, considering the growing complexity of telecommunication technology and the legitimate need of freedom for innovati
33、on, understand that it is not possible to make everything conforming to a single standard. Taking into account this limitation, they would like to have, when purchasing devices or services, at least a clear indication on how far interoperability is provided. The scope of the present document encompa
34、sses the main ICT services, such as fixed and mobile telephony basic and supplementary services, directory services, data transmission, Internet access, email, etc. even including requirements for services interoperability needed by certain categories of users and that are not necessarily envisaged
35、by the designers. The present document endeavours to give principles enabling for interoperability management in the standardization process according to the users needs. They are based on the result of a survey of users. Such principles are expected to help in identifying areas where users need int
36、eroperability and where standardization should allow it to be provided. The intention was to include the needs of every kind of users but unfortunately and despite many efforts, inputs about the needs of elderly and disable were very difficult to capture and only a few ones were provided belatedly.
37、Therefore an additional work would be needed to fully take into account such needs. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
