Method and arrangement for improved positioning
First Claim
1. A method in a core network node of improved positioning of a user equipment in a telecommunication system, said telecommunication system comprising the user equipment in communication with the core network node via a radio access network node, the method comprising, in response to a user equipment positioning event for said user equipment:
- providing user equipment identification data for said user equipment, said user equipment identification data comprising;
at least a parameter indicative of a type for said user equipment;
a confidence reporting principle;
a geographical reporting format comprising a geometrical shape with a size indicative of an uncertainty of a geographical position of said user equipment and a confidence value indicative of a probability that said user equipment is located within said geometrical shape, and wherein at least one parameter is indicative of whether a two dimensional or three dimensional confidence value is provided for said geographical reporting format; and
a positioning method associated with said geographical reporting format;
receiving user equipment positioning information from said radio access network node based on said user equipment positioning event, said user equipment positioning information comprising the geographical reporting format representative of the geographical position of said user equipment, and the positioning method applied;
determining a type of the user equipment based on a received signal including information concerning the type of the user equipment; and
correcting said received user equipment positioning information based on said provided user equipment identification data, a predetermined desired output geographical reporting format, said determined type of user equipment, and said positioning method applied.

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 user equipment identification data, a predetermined desired output geographical format, the determined user equipment type and the applied positioning method, whereby an improved positioning for the user equipment is enabled in the core network node.
