Embodiment approach

[0067] The mobile terminal 500 is configured to scan for WLAN access points and possibly other types of nodes in the environment. Optionally, the mobile terminal 500 may include a GNSS server configured to calculate the position of the mobile terminal 500 based on received satellite signals. And the mobile terminal 500 is configured to communicate with other devices via the WLAN 420 and / or via the cellular communication network 410 .

[0068] The cellular communication network 410 may be based on any kind of cellular system, for example, a GSM system, a 3rd Generation Partnership Project (3GPP) based on a cellular system like a WCDMA system or a system such as a system supporting high-speed packet access, a 3GPP2 system like a CDMA2000 system , LTE or LTE-Advanced (LTE-Advanced) systems, or other kinds of cellular systems like Worldwide Interoperability for Microwave Access (WiMAX) systems.

[0069] Each WLAN 420 includes at least one access point. A BSSID has been assigned ...

Abstract

An apparatus receives (111) information about at least two wireless access points obtained in a scan at a single location and retrieves (112) information from a record that is stored for a particular one of the at least two wireless access points. The apparatus determines (113) whether to update information about neighboring wireless access points in the record stored for the particular wireless access point by comparing received information with retrieved information. In case (114) it is determined to update information about neighboring wireless access points, the apparatus causes an update of information about neighboring wireless access points in the record stored for the particular access point based on the received information.

Description

technical field [0001] The present invention relates to stored information about wireless access points, and more particularly to the updating of such information. Background technique [0002] Modern global mobile and non-cellular positioning techniques are based on the generation of huge global databases including information on cellular and non-cellular. This information may originate in whole or in part from users of these positioning technologies. This approach is also known as "crowd-sourcing". [0003] The information provided by the user is typically in the form of a "fingerprint" that includes an indication of location based on estimates, for example, of received Global Navigation Satellite System (GNSS) satellite signals and data from cellular and / or Or measurements of one or more radio interfaces of non-cellular end systems. In the case of measurements for cellular signals, the results of the measurements may contain global and / or local identities of the observ...
