Intended readers of the present document are: standards developers; terminal manufacturers; assistive device manufacture

Introduction An eEurope community that promotes fair and comprehensive access to advanced information and communication services for all citizens must ensure that those citizens whose disabilities a
29、re such that they cannot use devices “designed-for-all“ are not excluded from the common access policies. In principle, all European citizens expect to have access to information through technology mediated services and devices. In the context of this report, this implies that all citizens can choos
30、e to have access through mobile platforms, and to choose the complexity of the devices and the range of services that meet their needs, at reasonable and equitable costs. Some users with disabilities, however, are unable to use conventional devices and services, even those designed according to the
31、“design-for-all“ principles, as their disabilities are too severe or their requirements conflict with those of people with a different disability. In this case, these users should be able to choose the mobile devices that they need to use, and to easily and cheaply enhance those devices and services
32、 with an adaptation appropriate to their needs. Examples could include a speaking output adaptation for blind people or icon representation of functions for people with reduced reading skills. ETSI ETSI TS 102 511 V1.1.1 (2007-08) 8 In order for this objective to be realised, mobile devices and serv
33、ices should be implemented with a standardized set of interfaces that can be the channel through which these adaptations become integrated with the rest of the system. Without this standardized interface, each adaptation will require significant technical expertise and effort, and will consequently
34、be expensive and practically unrealistic. People with disabilities will be confined to using a small subset of the available devices and services, and will not be able to join other citizens in selecting devices and services according to personal preferences (e.g. style, design, functionality), but
35、instead will have to persist with using specific devices long after they have ceased to be supported by manufacturers and operators, simply because it is impossible to replace them. A standardized set of interfaces will, therefore, encourage growth in the market for mobile devices and services by en
36、abling the large numbers of disabled and elderly people who are currently excluded to participate, and the strength of the European rehabilitation technology market, particularly the small and medium enterprises that currently dominate this sector. As one candidate technology that is present in all
37、mobile devices is AT commands, the work to promote increased accessibility and adaptability of the mobile devices is expected to include the upgrading of existing standards where the necessary AT commands 2 and 3 do not exist (as recommended in “Requirements for assistive technology devices in ICT“
38、7). Requirements on this set of interface standards have been collected in a process which has involved manufacturers of assistive devices and groups representing the user with different special needs. The draft versions have been presented to appropriate standards fora (e.g. 3GPP) and interested ma
39、instream mobile device manufacturers. The present document also provides a basis for national regulatory authorities to implement the Framework Directive (2002/21/EC) 28, enable member states to take specific measures for disabled end-users in order to ensure access to publicly available telephone s
40、ervices and emergency services in accordance with the Universal Service Directive (2002/22/EC) 29 and facilitate the implementation of the Public Procurement Directive (2004/18/EC) 36. ETSI ETSI TS 102 511 V1.1.1 (2007-08) 9 1 Scope The present document sets out the requirements for new AT command p
41、rotocols that can be used to enable assistive devices to interwork satisfactorily with mobile terminals over a range of suitable interfaces. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific referen
