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 3 years, in which the design of SMS was established.The work on the draft specification continued in the following few years, where Kevin Holley of Cellnet (now Telefónica O2 UK) played a leading role.
SMS, as used on modern devices, originated from radio telegraphy in radio memo pagers that used standardized phone protocols.
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 mentions for the first time the Technical Specification 03.40 "Technical Realisation of the Short Message Service". The first and very rudimentary draft of the technical specification was completed in November 1987.
These were defined in 1985 as part of the Global System for Mobile Communications (GSM) series of standards.
The protocols allowed users to send and receive messages of up to 160 alpha-numeric characters to and from GSM mobiles.
