subsequently use the SHA-1 algorithm to either calculate a response to the challenge or validate the response of
the other party, depending on which party initiated the Bluetooth link establishment process.
Controlling location-based services on the BlackBerry device
Third-party applications and preloaded BlackBerry applications on BlackBerry devices that support the GPS
feature can use the GPS feature by default. For example, BlackBerry® Maps is a preloaded application that uses
the GPS feature on BlackBerry devices to enable users to locate the global positions of their BlackBerry devices.
The BlackBerry Enterprise Server includes the following options to enable the BlackBerry Enterprise Server
administrator to control the GPS feature and the location-based services on supported BlackBerry devices that
use the feature.
Option Description
Turn off the GPS feature on BlackBerry devices. The following measures prevent third-party
applications and preloaded BlackBerry applications
from accessing the global position of the BlackBerry
device:
The BlackBerry Enterprise Server administrator
can set the Disable GPS IT policy rule to True to
prevent the BlackBerry device from permitting
third-party applications or preloaded BlackBerry
applications from accessing the GPS feature.
The BlackBerry Enterprise Server administrator
can set the Device GPS application control policy
rule to Not Permitted in the default application
control policy to prevent all third-party
applications from using the GPS feature.
Control use of the GPS feature by specific third-
party applications on the BlackBerry device.
The BlackBerry Enterprise Server administrator can set
the Device GPS application control policy rule to Not
Permitted in a specific application control policy to
prevent specific third-party applications from using
the GPS feature.
Prevent the BlackBerry device from reporting its
location to the BlackBerry Enterprise Server.
By default, the Enable Enterprise Location Tracking IT
policy rule is set to False to prevent the BlackBerry
device from using the GPS feature to report its
location to the BlackBerry Enterprise Server at regular
intervals. The BlackBerry Enterprise Server
administrator can turn on Enterprise Location
Tracking, specify a message that the BlackBerry device
displays to notify the BlackBerry device user when
Enterprise Location Tracking is enabled, and configure
the interval after which a BlackBerry device reports its
location to the BlackBerry Enterprise Server.
Turn off the BlackBerry Maps application on
BlackBerry devices.
The BlackBerry Enterprise Server administrator can use
the Disable BlackBerry Maps IT policy rule to specify
whether the BlackBerry Maps application is turned off
on the BlackBerry device.
