Abstract
Systems and methods for position updating for a mobile device are disclosed. A mobile device receives a first position data at a first time and queries for network information associated with a serving cell of a cellular network. The network information contains a radio signal level associated with the serving cell of the cellular network. The mobile device compares the radio signal level against a previously stored radio signal range received from a network server and determines a position updating opportunity for the mobile device based on the comparison. The network server assists the position updating process by acquiring, positioning data from a plurality of mobile devices operating in the cellular network. The network server determines a QoP information based on the acquired positioning data and transmits the QoP information to the plurality of mobile devices to be stored for position update.
