Abstract
Abstract A telecommunications system and method is disclosed for allowing an application requesting positioning of a mobile terminal to indicate the quality of positioning information desired, e.g., timeliness, accuracy, etc. In addition, prior to performing the positioning, the cellular network can determine whether the quality of service requested can be achieved, and if so, return the positioning information along with a message indicating that the quality of service requested was achieved. However, if the quality of service requested cannot be achieved, a failure message is sent to the requesting application and the positioning is not performed.
