SUPPORTING WIRELESS LOCAL AREA NETWORK BASED POSITIONING

摘要

An apparatus retrieves information on an availability of data on wireless local area networks for a particular area from a memory. The particular area is identified based on cellular measurements at a mobile terminal. The apparatus provides the retrieved information as a basis for a decision whether to perform a scan for wireless local area networks at the mobile terminal as a basis for a wireless local area network based positioning.
