Method for locating positioning device e.g. mobile phone, of user on e.g. bus map, involves collecting location data of positioning device relative to map using positioning data of positioning device, and providing collected location data

摘要

The method involves receiving (130) a positioning data (POS-U) of a positioning device (U). A location data (LOC-U) of the positioning device relative to a map are collected (220) using the positioning data of the positioning device, and the collected location data are provided (230), where the location data of the device corresponds to reference location data associated with reference positioning data that are closer to the received positioning data. Identification data (IDm) of the map are obtained (120) by reading an identifier e.g. barcode or radio frequency identification tag. Independent claims are also included for the following: (1) a positioning device comprising a positioning unit and a communication unit (2) a location assistance server for assisting a user of a positioning device to be located on a map (3) an assisted location system comprising a positioning device.
