Method and arrangement for high precision position reference measurements at indoor locations

A method in a telecommunication network for generating high precision position reference measurements at indoor locations, the method performed in one or several network nodes

• characterized by
• receiving information entities comprising one location from a list of locations and at least one of a time stamp or an identification of a mobile user equipment (UE) that has provided a high precision positioning result for said location;
• determining a tag reflecting radio propagation conditions at a location of the UE;
• and
• generating a high precision position measurement by correlating said information entities to said tag for constituting a tagged high precision position measurement to be provided to a positioning algorithm.

An arrangement (61) in a mobile telecommunication network for providing high precision position reference measurements at indoor locations, the arrangement located in one or several network nodes

• characterised in
• an interface (611) providing access for a mobile user equipment (62) to a list of locations;
• means (612) for requesting from said mobile user equipment (62) a high precision positioning measurement;
• means (613) for obtaining a high precision positioning result and means for determining whether said high precision positioning has failed;
• means (614) for storing of information entities comprising one location from said list of locations and at least one of a time stamp or an identification of said mobile user equipment;
• and
• means (615) for providing said information entities to a further network node.

An arrangement (63) in a mobile telecommunication network for generating high precision position reference measurements at indoor locations, the arrangement located in one or several network nodes,

• characterised in
• means (631) for receiving information entities comprising one location from a list of locations and at least one of a time stamp or an identification of a mobile user equipment (UE) (62) that has provided a high precision positioning result for said location;
• means (632) for determining a tag reflecting radio propagation conditions at a location of the UE;
• and
• means (633) for generating a high precision position measurement by correlating said information entities to said tag for constituting a tagged high precision position measurement to be provided to a positioning algorithm.
