Read Command:
+SBDREG?
Query the current SBD registration status of the A3LA-R. The response is of the form:
+SBDREG:<status>
<status>:
0
Detached
1
Not registered
2
Registered
3
Registration denied
The registration status is stored in A3LA-R non-volatile memory, and can therefore be queried
by the DTE after powering up.
A.8.110 +SBDAREG – Short Burst Data: Automatic Registration
Exec Command:
+SBDAREG=<mode>
Set the A3LA-R’ Auto-registration mode.
<mode>:
0
Disable automatic registration (default)
1
Set the Auto-registration mode to “Automatic”
2
Set the Auto-registration mode to “Ask”
When auto-registration is enabled, mode 1 or 2, the A3LA-R monitors its current location and
triggers an SBD auto-registration when it determines that it has moved sufficiently far away
from its last registered location. Note that auto-registration runs only while the A3LA-R is
attached to the GSS, i.e. the registration status is “Not registered” or “Registered”.
Auto-registration may only be used with system-provided location. If the DTE is providing its
own location (e.g. GPS), the DTE should use the manual registration command, +SBDREG.
Upon triggering in mode 1, “Automatic”, the A3LA-R autonomously initiates an SBD session in
order to perform a registration with its updated location. This session does not transfer any MO
or MT messages.
Upon triggering in mode 2, “Ask”, the A3LA-R reports to the DTE that it should register with the
system because its location has changed (see <event> below); it is then the responsibility of
the DTE to register via +SBDREG or +SBDIX. +SBDIX allows the DTE to register while including
an MO message and/or retrieving any MT message that is pending at the GSS.
When auto-registration is enabled, mode 1 or 2, the A3LA-R reports relevant events to the DTE
by issuing an unsolicited result code +AREG:<event>,<reg error>.
