摘要：
A method performed by a UE for obtaining positioning assistance data from a location server, wherein the UE and the location server are operating in a wireless communications network. The UE receives a system information broadcast from a radio network node. The UE further transmits a request for positioning assistance data to the location server in case the UE does not obtain the needed positioning assistance data via the radio network node broadcast system information. The UE further obtains carrier and/or RAT information used for the positioning assistance data broadcast. The UE further reselects or is redirected to the carrier and/or RAT used for the positioning assistance data broadcast.
