    36、ntially essential to the present document may have been declared to ETSI. The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: “Intellectual Property Rights (IPRs); Essential, or potentially Essential

    37、, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No g

    38、uarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Human Factors (HF). Ex

    39、ecutive summary Text communication services such as chat, instant messaging, SMS and e-mail are now mainstream digital services, but have the disadvantage that they do not provide a fluent conversation. Real time conversational text provides a fluency of conversation, which avoids the disjointed eff

    40、ects of speaking out of turn that often occurs in messaging systems. Real time conversational text has up till now been largely restricted to expensive specialized terminals used mainly by the deaf community. The present document describes a design for all solution providing real time conversational

    41、 services that support text, speech and optionally video on current and future networks. The present document identifies user requirements for a conversational text service in clause 6.1, describes the requirements for the solution in clause 6.2, and clauses 7 to 12 give details of how existing text

    42、phone systems can migrate to the new service in clause 13. Annex A reports the study of the many different textphone systems currently in use. Proposals for further work to deal with currently unsolved problems are contained in clauses 15 and 16. ETSI ETSI EG 202 320 V1.2.1 (2005-10) 9 1 Scope The p

    43、resent document sets out detailed and practical requirements for Duplex Universal Speech and Text (DUST) protocols and services that provide enhanced real time text and speech conversation for all users. The present document identifies existing textphones, chat systems and protocols, identifies user

    44、 requirements for effective text and telephone conversation, and gives methods of fulfilling these requirements. The present document identifies necessary extensions to signalling protocols and transport facilities of current multimedia systems to achieve the DUST requirements. In addition, the pres

    45、ent document sets out a migration process from existing national textphone systems. The present document points out where further standardization work is required to resolve any remaining problems. The present document contains information applicable to network operators, service providers, terminal

    46、 and network manufacturers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a
