Method for WLAN localization and location based service supply
First Claim
1. A method for WLAN localization and location based service supply, comprising:
- storing a WLAN data set of a geographical unit on a mobile device for the usage in the mobile device;
receiving WLAN signals by the mobile device from at least three WLAN senders;
self-sustained identifying of the WLAN senders by the mobile device on basis of the received WLAN signals;
calculating an actual position of the mobile device by the mobile device by comparing the WLAN data set with the received WLAN signals from the WLAN senders;
updating the WLAN data set as a function of the received WLAN signals, wherein the updating comprises;
comparing the WLAN data set with received WLAN signals with respect to the actual position;
sending a renewing signal with new WLAN data to a storing site of the WLAN data set in case of a deviation after the comparing; and
replacing data of the WLAN data set by the new WLAN data in case of a deviation after the comparing;
receiving an user demand for a location based service;
searching for at least one supply in a service data set by the mobile device on basis of the calculated actual position; and
supplying a location based service by the mobile device to a user of the mobile device on basis of the calculated actual position,wherein the WLAN Data set is a WLAN fingerprint of the geographical unit.

Abstract
A method is for WLAN localization and corresponding location based service supply. By providing a WLAN data set as an actual WLAN fingerprint of a geographical unit for the usage in a mobile device the user is enabled to localize himself self-sustained. Thereby the mobile device receives WLAN signals from at least three WLAN senders for the localization. Due to self-sustained identifying of the WLAN senders by the mobile device on basis of the received WLAN signals the mobile device may calculate the actual geographical position of the mobile device. The calculation is done on basis of the WLAN data set and on basis of the received WLAN signals from the at least three different WLAN senders. Furthermore a location based service is supplied by the mobile device the a user of the mobile device on basis of the calculated actual position.
