Description

This document describes the AT command interface specification that is supported by Huawei terminal product MU739 module. This document describes certain AT commands (implemented by terminal devices) of international standards such as 3GPP TS 27.007 3d0, 3GPP TS 27.005 320, and ITU-T V.250 according to the requirements of terminal devices. In addition, this document describes the proprietary AT command interfaces that are implemented by terminal devices. These proprietary AT command interfaces help implement a certain function.



This document does not describe the interfaces that have been defined by standards or implemented by the mobile terminal (MT) but are not required by the MU739. The description of AT command interfaces covers only the data packets of interfaces and the methods and processes for the terminal equipment (TE) and the MT to use interfaces, excluding the contents that are not directly related to interfaces. In addition, this document describes only the AT command interfaces falling within the range of Rm interfaces between the TE and MT, excluding the AT command interfaces falling within the range of Um interfaces between the MT and Interworking Function.
