Abstract

In a method of improved positioning of user equipments in a telecommunication system comprising at least one user equipment in communication with a core network node via a radio access network node, in response to a user equipment positioning event for said at least one user equipment performing the following steps. Providing S10 user equipment identification data in the core network node for each at least one user equipment, the data comprising at least a parameter indicative of a type for the user equipment, a confidence reporting principle, a geographical reporting format type, and a positioning method, associated with said user equipment type. Providing S20 positioning information in the core network node from the radio access network node based on the positioning event. The positioning information comprising a geographical format representative of the geographic position of the user equipment, and a positioning method applied in at least the radio network node. Subsequently, determining S30 the type of the at least one user equipment, from information signaled to the core network node. Finally, correcting/adapting S40 the provided positioning information based on the provided …
