Overall Description

1 Overall Description

This chapter briefly describes the contents and organization of this document and focuses on the basic knowledge of AT command interfaces.

1.1 Content Description

This document describes the AT command interface specification that is supported by Huawei terminal product MC509 module. This document describes certain AT commands (implemented by terminal devices) of international standards such as TIA/EIA/IS-707-A.3,GSM 07.07, GSM 07.05, and International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) V.250 [14] according to the requirements of terminal devices. In addition, this document describes the proprietary AT command interfaces that are implemented by terminal devices.

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 MC509. 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 (IWF).
