The invention discloses a method for obtaining a location of mobile station connected in a mobile network where a request for the location contains a condition specifying if a location stored in the mobile network can be used. The condition comprises an expression regarding an accuracy threshold for the location. When the stored location does not meet the condition the mobile network actively determines the location of the mobile station. The location is reported back. The method can be applied in a Home Location Register in the network, in a Visiting Mobile Service Center or in both. The HLR contains location information for registered mobiles and the VMSC for connected mobiles. |
