1.3 Basic AT Command Processing Principles
1.3.1 Ports
The ME906s provides three ports to interact with its host:
- Network Card port: simulated using USB, for establishing data connection.
Port name: HUAWEI Mobile Connect - Network Card
- PCUI port: simulated using USB, for AT command interaction only.
Port name: HUAWEI Mobile Connect - PCUI Interface
- GPS port: simulated using USB, for reporting NMEA data.
Port name: HUAWEI Mobile Connect - GPS Interface
The ME906s also provides a port for debugging:
- DIAG port: simulated using USB, for DIAG (diagnostic) command interaction (mainly
used to debug modules at present).
Port name: HUAWEI Mobile Connect - Application Interface
A host controls a module using AT commands. If AT commands are unavailable, a module can
be deemed as unavailable.
1.3.2 AT Command Processing Mechanism
A module processes AT commands from the ports (MODEM, PCUI, and GPS) in series. An
AT command can be processed when and only when the previous AT command processing
has been completed. If the module is processing an AT command, a new AT command from
the same port will be buffered and other commands from other ports will be buffered until the
current AT command is processed.
The processing of an AT command starts when the AT command is entered from the TE, and
ends when the UE (the module) returns all the results in response the command.

1.3.3 Recommended Timeout Mechanism for AT Commands
Processed by a Host
A module processes AT commands in series. Do not send another AT command before the
result for the current command is returned or the current command times out (except when the
current command is an interruptible AT command). The following table lists AT command
timeout durations (starting from the time when an AT command arrives at a port).
Table 1-1 AT command timeout duration
AT Command
Timeout Duration
General AT commands
30s
AT+CMGS (used to send PDU messages)
60s
AT+COPS=? (used to search for networks)
120s
After an AT command times out, it is recommended that the host check whether the module is
functioning normally. The following procedure is provided for your reference:
- The host sends the AT command to the module.
- If the module returns failure information, go to step 5. Otherwise, go to step 3.
- If the module returns success information, the module is functioning normally.

12
- If the host times out (the host waits for a response for over 30 seconds) three times when
waiting for the response from the module, go to step 5. Otherwise, go to step 1.
- The host deems that the current module does not exist or is unavailable. Close the port,
stop sending all AT commands, exit the procedure to determine whether the module is
normal, and re-search for modules.

4 BodySAR Application Scenarios
4.1 Overview
Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed by the
body when exposed to an RF electromagnetic field. It is commonly used to measure power
absorbed from mobile phones. The greater the SAR value, the greater the radiation effect on
humans.
For user equipment (UE) such as modules, their SAR value increases as their transmitted
power increases.
At present, most vendors' tablets have passed SAR tests. Generally, these products have
embedded proximity sensors. When the sensors detect that a human is in the proximity of or
in contact with the UE, they will notify the UE so that the UE will reduce the transmitted
power. When the human is no longer in the proximity of or in contact with the UE, the sensors
also notify the UE so that the UE will restore the transmitted power.

4.6 Usage Description Of BodySAR Feature
4.6.1 Reference Description
After a module is powered on, the default BodySAR function status is disabled, and the
default power control function in the system is used.
The maximum transmitting power parameters take effect in real time only when the following
requirements are met:
- The AT^BODYSARWCDMA, AT^BODYSARGSM and AT^BODYSARLTE
commands are used to set the maximum transmitting power parameters successfully.
- The AT^BODYSARON=1 command is used to enable the BodySAR function.
When the maximum transmitting power parameters are not set or the BodySAR function is
disabled, the default power control function in the system is used.
After the maximum transmitting power parameters are set, the AT^BODYSARON=0
command can be used to disable the BodySAR function. Then the default maximum
transmitting power is resumed. If the AT^BODYSARON=1 command is used to enable the

6 SMS Application Scenarios
6.1 Overview
Short Message Service (SMS) is a text messaging service using a service center (SC) to
transfer short text messages between GSM MEs and Short Message Entities (SMEs). ME906s
only supports protocol data unit (PDU) mode message.
A message must contain the following information before it is sent:
For a PDU mode message:
- Length of TPDU package
- Message content: To compose or send a PDU mode message, the message must contain
all the message attributes and be encoded in PDU format. A PDU consists of the
following:
− Service Center Address (SCA): composed of the address length, SCA type and SCA
reverse byte.
− First octet: contains the message type indicator, TP-RP, TP-UDHI, TP-SRR, TP-VPF,
TP-RD, and TP-MTI.
− Short text message statement.
− Destination address: consisting of the destination address, address length and
destination address type.
− Protocol identifier.
− Data encoding scheme.
− Validity duration.
− Data length.
− User data: consisting of the user data header and the data encoded in PDU format.
Figure 6-1 shows an example of data encoded in PDU format of submitted type.

The SMSC address provided by the service provider must be specified. In PDU mode, the
SMSC address is contained in the PDU packets. Therefore, in PDU mode, the AT+CSCA
command is optional.
To use the SMS features specified in the GSM 07.05 Phase 2+, the AT+CSMS command
must be used to enable the features.
Use the AT+CNMI command to set the unsolicited indications.
Use the AT+CPMS command to select the preferred short message storage (SIM or ME). The
ME906s supports only the SM (SIM card) storage.
Use the AT+CGSMS command to select the MO SMS bearer domain (PS or CS domain). For
ME906s, the CS domain is the preferred MO bearer domain.

Standalone
This is a traditional
GPS positioning
method. Using this
method, a module
receives satellite
signals directly and
makes calculations
to obtain positioning
results.
No communication
with the network is
invoked, incurring
no data traffic
between the module
and the network.
Long time to first fix

Mobile Station
Based (MSB)
positioning using the
User Plane Protocol
Requests the
assistant data from
the network to assist
and accelerate the
positioning. This
method is one of the
Assisted GPS
(A-GPS) methods.
- Significantly
reduces the
TTFF after cold
start and
increases the rate
of successful
positioning.
- Enables
positioning in
environments
with very poor
satellite signals.

Mobile Station
Assisted (MSA)
using the User Plane
Protocol
Requests data from
the network to assist

sends the satellite
data to the network
for calculations, and
the network returns
the calculation
results to the
module. This
method is one of the
A-GPS methods.
- Reduces the
TTFF after cold
