适用范围

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. 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].
