Abstract

Methods, systems, devices and computer program products for executing a predetermined routine including one or more location determination modes to determine a geographic position, i.e., the location of a wireless communication device. In certain aspects, the predetermined routine may be configured to adjust the Quality of Service (QoS) for one or more of the location determination modes implemented in the routine. Based on the pre-configuration of the routine, adjustment of the QoS of one or more location determination modes may occur as a matter of course or the routine may be configured to adaptively adjust the QoS based on conditions, such as network conditions, environmental conditions and the like, existing at the point in time in which the location determination mode is executed.
