Rapporteur:  MONRAD, Atle
Descendant(s):  TS 27.007    

This TS specifies a profile of AT commands and recommends that this profile be used for controlling Mobile Equipment (ME) functions and GSM network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). The command prefix +C is reserved for Digital Cellular in ITU T Recommendation V.25ter.

This TS has also the syntax details used to construct these extended GSM commands. Commands from ITU T Recommendation V.25ter and existing digital cellular standards (TIA IS 99 and TIA IS 135) are used whenever applicable. Some of the new commands are defined in such a way that they can be easily applied to ME of networks other than GSM. ITU T T.31 and T.32 fax AT commands may be used for GSM fax transmission from TE. GSM Short Message Service AT commands are defined in TS 07.05. GPRS AT commands are defined in clause 10 of this TS.

This TS assumes an abstract architecture comprising a TE (e.g. a computer) and a ME interfaced by a TA. The span of control of the defined commands should allow to handle any physical implementation that this abstract architecture may lead to:
  • TA, ME and TE as three separate entities;
  • TA integrated under the ME cover, and the TE implemented as a separate entity;
  • TA integrated under the TE cover, and the ME implemented as a separate entity;
  • TA and ME integrated under the TE cover as a single entity.
