Method for determining position of mobile radio terminal, involves registering mobile radio terminal in radio cell of mobile network operator, where wireless local area network module of mobile radio terminal receives user identification

摘要

The method involves registering a mobile radio terminal (1) in a radio cell (13,14,15) of a mobile network operator (12). A Wireless local area network (WLAN)module (3) of the mobile radio terminal receives user identification (4,5,6) of a wireless local area radio network (7,8,9). The mobile radio terminal transmits the user identification of the wireless local area radio network to the mobile network operator by a mobile. Independent claims are also included for the following: (1) a mobile radio terminal with a position determining module; and (2) a system for determining the position of a mobile radio terminal.
