Foreword
This Technical Specification (TS) has been produced by the 3rd Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change
following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-
released by the TSG with an identifying change of release date and an increase in version number as
follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements,
corrections, updates, etc.
the third digit is incremented when editorial only changes have been incorporated in the
document.
z
Scope
1
The present document specifies a profile of AT commands and recommends that this profile be used for
controlling Mobile Termination (MT) functions and GSM/UMTS 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.250 [14]. The present document has also the syntax details used to construct
these extended GSM/UMTS commands. Commands from ITU- T Recommendation V.250 [14] and existing
digital cellular standards (TIA IS- 99 [15] and TIA IS- 135 [16]) are used whenever applicable. Some of the
new commands are defined such way that they can be easily applied to MT of networks other than
GSM/UMTS. ITU- T T.31 [11] and T.32 [12] fax AT commands may be used for GSM/UMTS fax
transmission from TE. GSM/UMTS Short Message Service AT commands are defined in 3GPP TS
27.005 [24]. GPRS AT commands are defined in clause 10 of this specification. The present document
assumes an abstract architecture comprising a TE (e.g. a computer) and a MT interfaced by a TA (see
figure 1). The span of control of the defined commands should allow to handle any physical implementation
that this abstract architecture may lead to:
- TA, MT and TE as three separate entities;
- TA integrated under the MT cover, and the TE implemented as a separate entity;
- TA integrated under the TE cover, and the MT implemented as a separate entity;
- TA and MT integrated under the TE cover as a single entity.
The commands described in the present document may be observed on the link between the TE and the TA.
However, most of the commands retrieve information about the MT, not about the TA.

Figure 1: Setup
Interface between TE and TA is intended to operate over existing serial (ITU- T Recommendation V.24)
cables, infrared link, and all link types with similar behaviour. For correct operation many of the defined
commands require eight bit data and therefore it is recommended that TE- TA link is set to eight bits/ byte
mode. (For infrared operation implementation refer informative references IrDA. For embedding AT
commands and data during on-line data state refer TIA- 617/ITU-T V.80.) Interface between TA and MT is
dependent on the interface in the MT.
The functional blocks shown in Figure 1, using AT commands, shall follow the principles described in the
interactions handling framework 3GPP TS 23.227 [63].

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, edition number, version number, etc.)
or non- specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document
(including a GSM document), a non-specific reference implicitly refers to the latest version of that
