Methods, configuration and computer program having program code means and computer program product for determining a position of a mobile communications device within a communications network

A method for determining a position of a mobile communications device in a communications network, comprising:

• communicating between a first base station and the mobile communications device using a first communication signal;
• communicating between a second base station and the mobile communications device using a second communication signal;
• determining a first possible location area for the mobile communications device using a first communication signal;
• determining a second possible location area for the mobile communications device from the second communication signal of the second communication;
• combining the first possible location area and the second possible location area using a non-linear, quantity-based filter;
• and
• determining the position of the mobile communications device to be a location area common to both the first and second base location areas.

A system to determine a position of a mobile communications device in a communications network having a first base station to communicate with the mobile communications device using a first communication signal, and having a second base station to communicate with the mobile communications device using a second communication signal, the system comprising:

• a first location determining unit used by the first base station to determine a first possible location area for the mobile communications device using the first communication signal;
• a second location determining unit used by the second base station to determine a second possible location area for the mobile communications device using the second communication signal;
• a location overlay unit that combines the first possible location area and the second possible location area using a non-linear quantity-based filter, and that determines a common location area;
• and
• a position determining unit to determine the position of the mobile communications device using the common location area.

A computer readable medium storing a program to control a computer to perform a method for determining a position of a mobile communications device in a communications network, the method comprising:

• communicating between a first base station and the mobile communications device using a first communication signal;
• communicating between a second base station and the mobile communications device using a second communication signal;
• determining a first possible location area for the mobile communications device using the first communication signal;
• determining a second possible location area for the mobile communications device from the second communication signal;
• combining the first possible location area and the second possible location area using a non-linear, quantity-based filter;
• and
• determining the position of the mobile communications device to be a location area common to both the first and second base location areas.
