Abstract
High precision UE position estimates derived by OTDOA positioning in an LTE network are provided to other networks (e.g., WCDMA and/or GSM), along with inter-RAT measurements performed on the other networks, to support fingerprinted positioning databases in the other networks. Signaling is provided enabling LTE UE position estimates to be used as reference points in the fingerprinting database in each of GSM control plane AECID positioning, GSM user plane AECID positioning, WCDMA control plane AECID positioning, and WCDMA user plane AECID positioning. In support thereof, inter-RAT measurement supporting the population of databases in WCDMA and GSM, using fingerprints and reference measurements in LTE; the use of OTDOA positioning to generate the LTE UE position estimates, and the required signaling are disclosed. The AECID databases in WCDMA and GSM networks do not have own-network serving cells at the top hierarchical level, since the inter-RAT measurements are performed in LTE.
