Abstract

Techniques are disclosed for providing an indication of location service availability and the quality of available location services for a mobile station. A required location quality of service (LQoS) parameter is acquired. The required LQoS parameter may be a minimum position accuracy value, a maximum response time value, or a maximum age of position information value. An actual LQoS value is then determined. If the actual LQoS value does not satisfy the required LQoS parameter, then an indicator is provided that location services are not available for the mobile station. For example, a visual indicator may be displayed indicating that location services are not available. On the other hand, if location services are determined to be available, a relative strength measure of position accuracy is calculated and a visual indicator of the strength of the position accuracy is provided.
