Editing SMS (section)

=== Early development ===
The technical development of SMS was a multinational collaboration supporting the framework of standards bodies.  Through these organizations the technology was made freely available to the whole world.<ref>See also [[Friedhelm Hillebrand]] "GSM and UMTS, the creation of Global Mobile Communication", Wiley 2002, chapters 10 and 16, {{ISBN|0-470-84322-5}}</ref>

The first proposal which initiated the development of SMS was made by a contribution of Germany and France in the GSM group meeting in February 1985 in Oslo.<ref>GSM document 19/85, available on the GSM-SMG Archive DVD-ROM</ref> This proposal was further elaborated in GSM subgroup WP1 Services (Chairman Martine Alvernhe, France Telecom) based on a contribution from Germany. There were also initial discussions in the subgroup WP3 network aspects chaired by Jan Audestad (Telenor). The result was approved by the main GSM group in a June 1985 document which was distributed to industry.<ref>GSM document 28/85r2, available on the GSM-SMG Archive DVD-ROM</ref> The input documents on SMS had been prepared by Friedhelm Hillebrand of [[Deutsche Telekom]], with contributions from Bernard Ghillebaert of [[France Télécom]]. The definition that Friedhelm Hillebrand and Bernard Ghillebaert brought into GSM called for the provision of a message transmission service of alphanumeric messages to mobile users "with acknowledgement capabilities". The last three words transformed SMS into something much more useful than the electronic paging services used at the time that some in GSM might have had in mind.<ref>{{cite web|title=So who really did create SMS?|url=http://www.gsmhistory.com/sms/|publisher=Stephen Temple|access-date=April 6, 2013|date=February 24, 2013|archive-date=May 11, 2013|archive-url=https://web.archive.org/web/20130511181922/http://www.gsmhistory.com/sms/|url-status=live}}</ref>

SMS was considered in the main GSM group as a possible service for the new digital cellular system. In GSM document "''Services and Facilities to be provided in the GSM System,''"<ref name="GSM 28/85"/> both mobile-originated and mobile-terminated short messages appear on the table of GSM teleservices.<ref name="GSM 28/85"/>

The discussions on the GSM services were concluded in the recommendation GSM 02.03 "''TeleServices supported by a GSM [[Public land mobile network|PLMN]].''"<ref name="GSM 02.03">{{cite web |url=https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=29 |title=Teleservices Supported by a GSM Public Land Mobile Network (PLMN) |id=GSM TS 02.03}}</ref> Here a rudimentary description of the three services was given:

# Short message mobile-terminated (SMS-MT)/ Point-to-Point: the ability of a network to transmit a Short Message to a mobile phone. The message can be sent by phone or by a software application.
# Short message mobile-originated (SMS-MO)/ Point-to-Point: the ability of a network to transmit a Short Message sent by a mobile phone. The message can be sent to a phone or to a software application.
# Short message [[Cell Broadcast|cell broadcast]].<ref name="GSM 02.03"/>

WP4 created a Drafting Group Message Handling (DGMH), which was responsible for the specification of SMS. Finn Trosby of Telenor chaired the draft group through its first three years, in which the design of SMS was established. DGMH had five to eight participants, and Finn Trosby mentions as major contributors Kevin Holley, Eija Altonen, Didier Luizard and Alan Cox. The first action plan<ref>Document GSM IDEG 79/87r3, available on the GSM-SMG Archive DVD-ROM</ref> mentions for the first time the Technical Specification 03.40 "Technical Realisation of the Short Message Service". Responsible editor was Finn Trosby. The first and very rudimentary draft of the technical specification was completed in November 1987.<ref>GSM 03.40, WP4 document 152/87, available on the GSM-SMG Archive DVD-ROM</ref> However, drafts useful for the manufacturers followed at a later stage in the period. A comprehensive description of the work in this period is given in.<ref>{{cite journal |author=Finn Trosby |url=http://www.telenor.com/telektronikk/volumes/pdf/3.2004/Page_187-194.pdf |title=SMS the strange duckling of GSM |journal=Telektronikk |volume=3 |date=2004 |archive-url=https://web.archive.org/web/20070925185855/http://,www.telenor.com/telektronikk/volumes/pdf/3.2004/Page_187-194.pdf |archive-date=September 25, 2007 |url-status=dead}}</ref>
