Chapter 16 – Data Commands
96 Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide
R-SCH Selection $QCMIP
Description: This command is used to enable or disable mobile IP.
The default value is carrier-specific.
This command is for test purposes only and should not be issued by the mobile phone user.
Syntax: AT$QCMIP=<Val>
Command
Possible Responses
AT$QCMIP?
Note: Display the current setting
$QCMIP: 1
OK
Note: Command is valid
AT$QCMIP=?
Note: Display the range of values
$QCMIP: (0-2)
OK
Note: Command is valid
AT$QCMIP=0
Note: Set value to 0
OK
Note: Command is valid
Values: <Val>
0 Mobile IP disabled, Simple IP only.
1 Mobile IP preferred. In the initial MIP registration, if the network does not
support Mobile IP, then the mobile automatically reverts to Simple IP (force a
PPP renegotiation by sending a LCP C-Req).
However, if a Mobile IP session is registered, and then enters a network that
does not support Mobile IP, the mobile will drop the session and inform the
upper layers of the failure (for example, by dropping DCD to a laptop).
2 Mobile IP only. The mobile will make data calls only when Mobile IP is
supported in the network. During a MIP session, if the mobile hands off to a
network that does not support MIP, then the mobile will drop the session and
inform the upper layers of the failure (for example, by dropping DCD to a
laptop).
Note: When the AT$QCMIP value is changed to 1 or 2, this modifies the value of
AT+CRM to 2. AT+CRM with a value of 2 enables network model operation.
Changing the value to 0 will reset the AT+CRM to its original value.
MIP Selection $QCMIPP
Description: This command is used to select and activate an MIP user profile.
Syntax: AT$QCMIPP
Command
Possible Responses
AT$QCMIPP?
Note: Display the current setting
$QCMIPP: 0
Note: User profile 1 is currently used
AT$QCMIPP=2
Note: Set to user profile 2
OK
Note: Command is valid
AT$QCMIPP=?
ote: Display the range of values
$QCMIPP: (0-5)
OK
Note: Command is valid
Note: Takes a profile number between 0 and 5. This value is stored in NV. This AT
command is used to configure Dial-Up Networking. Although 5 is the absolute
maximum profile number, the actual number may be limited by the carrier.
