10.17 +SBDREG - Short Burst Data: Network Registration
Exec Command: +SBDREG[=<location>]
Triggers an SBD session to perform a manual SBD registration.
This command initiates an SBD session to perform a manual SBD registration, consisting of an attach and
location update. This session does not transfer any MO or MT messages.
Note: The ISU restricts the number of manual and automatic registrations to one every 3 minutes.
Successive attempts within 3 minutes will return an error code indicating that the FA should try later (see
error 36 below).
Note: A user can send an MO SBD message and register at the same time by using the +SBDIX command.
The +SBDIX command always performs a registration attempt and should be used for an application
requiring SBD Ring Alert. The +SBDI command never includes an SBD registration and should be used
for an application that does not require SBD Ring Alert.
