Abstract
The invention disclosed is a location blocking service for use in a wireless network that tracks the location and identity of network users, such as networks complying with enhanced 911 standards. The service provides a network user with the ability to prevent the location of her wireless handheld device from being disclosed to parties other than the wireless network provider and PSAPs (Public Safety Answering Points). The network user blocks the forwarding of location information by signaling to the wireless handheld device when the location information originates from the wireless handheld device, or by signaling to the network when the location information originates from the wireless handheld device or the network. Primary components of the present invention include at least one user interface and at least one location block processor provisioned in the wireless handheld device and/or the wireless network. The user interface prompts the user of the handheld device to enter the commands that send the signals to the device or network.
