Abstract: An apparatus obtains results of measurements, which are performed by a mobile device on signals of communication nodes. The measurement results for each of the communication nodes include a signal strength related value and an identification of the communication node. The apparatus obtains for one of the communication nodes a stored indication of a location and a stored signal strength related value and determines a difference between measured and stored signal strength related values. The apparatus estimates the position of the mobile device based on the results of measurements and on obtained stored radio model data. In the case that the determined difference for the at least one communication node falls short of a predetermined threshold, the apparatus determines a distance between estimated position and indicated location for the at least one communication node, as an indication of a health state of stored radio model data.

In accordance with another embodiment, a proprietary extension is introduced at the highest abstraction level. For example and in an actual implementation, a vendor can define that in the beginning of the proprietary payload, the proprietary extension is defined, whether the proprietary payload contains a request, assistance, etc.

Abstract: A system for supporting electronic positioning in apparatuses. Apparatuses may receive various wireless signals over time. The strength of the received wireless signals may be determined by the apparatuses, and based on this determination an occurrence for each received wireless signal may be accumulated in a histogram in the apparatus.
