ENHANCEMENT OF POSITIONING QUALITY OF SERVICE

摘要

There is provided a method implemented by an electronic processing apparatus for responding to a request for a mobile terminal's geographic position. The method comprises computing (310) a joint QoS metric for the request, wherein the joint QoS metric is a single metric that jointly depends on two or more individual positioning QoS parameters associated with the request, by: determining a service type of the request; determining weighting values based on the service type; and computing the joint QoS metric as a weighted combination of the two or more individual positioning QoS parameters according to said weighting values. The method further comprises sending (320) the request and the joint QoS metric to another apparatus for selection of a positioning method, or a sequence of positioning methods, based on the joint QoS metric.
