Full Description

The present document specifies a profile of AT commands and recommends that this profile be used for controllingMobile Equipment (ME) functions and GSM network services from a Terminal Equipment (TE) through TerminalAdaptor (TA). The command prefix +C is reserved for Digital Cellular in ITU-T Recommendation V.25ter [14]. Thepresent document has also the syntax details used to construct these extended GSM commands. Commands from ITU-TRecommendation V.25ter [14] and existing digital cellular standards (TIA IS-99 [15] and TIA IS-135 [16]) are usedwhenever applicable. Some of the new commands are defined in such a way that they can be easily applied to ME ofnetworks other than GSM. ITU-T T.31 [11] and T.32 [12] fax AT commands may be used for GSM fax transmissionfrom TE. GSM Short Message Service AT commands are defined in GSM 07.05 [24]. GPRS AT commands are definedin clause 10 of the present document.The present document assumes an abstract architecture comprising a TE (e.g. acomputer) and a ME interfaced by a TA (see figure 1). The span of control of the defined commands should allow tohandle 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.>/li>
