The present invention concerns, inter alia, a method for generating location data for locating a mobile communication terminal (20) in a cellular communication network, said communication network being comprised of a number of radio cells (40, 50, 60). The basics are that the communication terminal (20) successively establishes a connection to a number of two or more radio cells (40, 50, 60) having the same and/or different field strengths, in that the communication terminal (20) maintains the connection to the respective radio cell (40, 50, 60) for a defined time period, and in that after the defined time period has elapsed, the communication terminal (20) terminates the connection to the radio cell (40, 50, 60) and establishes a connection to the next radio cell (40, 50, 60). The information items arising from this process are used on the network side to generate location data by means of which the communication terminal (20) can be located. The locating procedure is simple and inexpensive, particularly since no chargeable data connections are made.
A method for generating location data for locating a mobile communication terminal in a cellular communication network, said communication network being comprised of a number of radio cells, said method comprising that the communication terminal successively establishes a connection to a number of three or more radio cells having the same and/or different field strengths, that the communication terminal maintains the connection to a particular radio cell to which the communication terminal has established a communication for a defined time period, and that after the defined time period has elapsed, the communication terminal terminates the connection to the radio cell and establishes a connection to the next radio cell.
A communication terminal for communication in a cellular communication network comprising a number of radio cells, said communication terminal comprising a device for generating electrical energy, a case, and a communication module for establishing a communication connection of the communication terminal to the radio cells of the communication network, said communication terminal further comprising a connection establishing device that is designed to enable the communication terminal to successively establish a connection to a number of three or more radio cells having the same and/or different field strengths, said communication terminal being adapted for maintaining the connection to the corresponding radio cell to which the communication terminal has established a communication for a defined time period, and after the defined time period has elapsed, for terminating the connection to the corresponding radio cell and for establishing a connection to the next radio cell.
