GPRS Parameters
This section is used for setting parameters of connection to a GPRS
access point (Fig. 29).
If the
“Auto detect APN settings”
feature is enabled all connection
options are set automatically depending on the communication service
provider.
i
The automatic detection feature uses a predefined set of providers
shown whenever the “Extra” hyperlink is pressed.
To specify options manually disable “Auto detect APN settings” feature
and set access point options. The required settings obtain from the
communication service provider.
“Do not enable GPRS in roaming”
To allow money savings, there is an option for an automatic disabling
of the connection to the monitoring server in case the mobile object
enters a roaming zone. In this case, the object travel data are stored in
the “black box” of the system and are later transferred to the monitoring
system server after the object returns to its home mobile network.
Use of two SIM cards registered in different regions or countries allows
constant receipt of data from any object that frequently crosses the
roaming zone boundaries without costly roaming fees. Whenever a
roaming zone boundary is crossed, the tracker switches to the SIM card,
to which the current zone is home-base.
If both SIM cards are registered in a different regions (country) and the
GPRS channel connection is off while in roaming, the tracker will not
connect to the monitoring system server until it returns to its home
network or its settings are changed (incoming calls over CSD/voice
channel are available).
