Positioning

The present invention relates to a method for a network entity, NE, to optimize positioning of a user equipment, UE, (UE4) where the reliability of the positioning of a UE (UE4) depend on static circumstances and situational/environmental circumstances. Static circumstances are the sensor capabilities and sensor quality related to the UE (UE4) and general system limitations, and they remain the same regardless of the position (p1, p2, p3, ..., p6) of the UE (UE4). Situational or environmental circumstances depend on the situation or environment of the UE, and they change with the position (p1, p2, p3, ..., p6) and/or other physical states of the UE (UE4). The invention teaches that the NE request a quality report from a measurement unit, MU, to enable the MU to report on quality changes due to situational or environmental circumstances to the NE in order to enable the NE to decide on the best positioning method for the UE (UE4) in the current situation.
