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>.
