KB14430 - How to control location-based services on the BlackBerry smartphone
KB14430 - How to control location-based services on the BlackBerry smartphone
Environment
- BlackBerry® Enterprise Server version 4.1 SP 5
- BlackBerry® Device Software version 4.3 through 4.7
Overview
Third-party applications and preloaded BlackBerry smartphone applications on BlackBerry smartphones that support the Global Positioning System (GPS) feature can use the GPS feature by default. For example, BlackBerry® Maps is a preloaded application that uses the GPS feature on the BlackBerry smartphone to allow BlackBerry smartphone users to locate the global positions of their BlackBerry smartphones. The BlackBerry Enterprise Server includes options to allow the BlackBerry Enterprise Server administrator to control the GPS feature and the location-based services on supported BlackBerry smartphones that use the feature.
Note: The BlackBerry® Infrastructure does not store the locations of BlackBerry smartphones. When the BlackBerry smartphone sends the identity of the wireless service provider with which it is registered to the BlackBerry Infrastructure, the BlackBerry Infrastructure retrieves the ephemeris data for each GPS satellite signal on the wireless network and sends it to the BlackBerry smartphone. The GPS receiver on the BlackBerry smartphone then knows the location of each GPS satellite in the wireless coverage area. The BlackBerry smartphone uses this data to calculate its own location, but the BlackBerry smartphone does not report its location to the BlackBerry Infrastructure.
Resolution
Disable the GPS feature on the BlackBerry smartphone
The following measures prevent third-party applications and preloaded BlackBerry applications from accessing the global position of the BlackBerry smartphone:
- The BlackBerry Enterprise Server administrator can set the BlackBerry smartphone 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.
- Using BlackBerry Enterprise Server version 4.1 SP 5, the BlackBerry Enterprise Server administrator will be able to set the Disable GPS IT policy rule to True to prevent BlackBerry smartphones that are running BlackBerry Device Software version 4.3 or later from permitting third-party applications and preloaded BlackBerry applications from accessing the GPS feature.
Control use of the GPS feature by specific third-party applications on the BlackBerry smartphone
The BlackBerry Enterprise Server administrator can set the BlackBerry smartphone 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 smartphone 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 smartphone 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 smartphone displays to notify the BlackBerry smartphone user when Enterprise Location Tracking is enabled, and configure the interval after which a BlackBerry smartphone reports its location to the BlackBerry Enterprise Server.
Disable the BlackBerry Maps application on the BlackBerry smartphone
The BlackBerry Enterprise Server administrator can use the Disable BlackBerry Maps IT policy rule to specify whether the BlackBerry Maps application is disabled on the BlackBerry smartphone.
