HUAWEI UMTS Datacard/Modem AT Command Interface Specification
This Document describes the AT command-based communication interface
between TE and MS of Huawei UMTS Datacard/Modem. The interface can
implement the functions such as voice call, SMS, telephone service,
supplementary service, and network setting. This document describes the
AT interface of Huawei UMTS Datacard/Modem. The description on the AT
interface is only limited to the interface packet itself, the usage and
use procedure of TE and MS, and does not cover the contents which are
not directly related to the interface. HUAWEI UMTS Datacard/Modem is a
wireless terminal of the PCMCIA or Express or USB interface. It is used
together with PC to provide data service, voice and SMS functions. This
document describes the AT interface.
Therewith no description or definition explain for the document interface, and no temporary support to all kinds of parameter values, so no suggestion of usage. For the extended interface, parameters can be added behind the AT command. If the interface fails to meet the new requirements as detected in the later stage of product development, new parameters can be added on the basis of the original interface. In addition, for all the currently available interfaces, if the command received by MS is not identifiable, the “result code” of COMMAND NOT SUPPORT will be reported; if there is one surplus command parameter, the MS will report the “result code” of the corresponding TOO MANY PARAMETERS. No equal mark itself is deemed a surplus command parameter. All newly added AT command interfaces of the E630 project team begin with “^”. This project team specifies that: In the AT command name such as “AT^XXX”, the number of X cannot be more than 9 currently. All interfaces herein refer to the interfaces between TE and MS, and are used for guiding the implementation of the function requirements
