1. In a mobile telecommunications system comprising:

  • a network including a plurality of base stations for defining communications cells; and

    first and second user equipment for communicating with the network, said plurality of base stations including at least one home base station defining a home cell associated with said first user equipment and not with said second user equipment, said home cell overlapping in coverage with a communications cell usable by both said first and second user equipment, a method for measuring a home cell comprising the steps of;

    acquiring, at the network, position data indicative of the position of the first user equipment;

    determining whether the first user equipment is close to the home cell by using the acquired position data;

    sending a cell measurement control message from the network to the first user equipment via a base station specifying measurements of said home cell when the first user equipment is close to the home cell;

    performing, at the first user equipment a fine position measurement;

    determining at the first user equipment whether the first user equipment is close to the home cell, based on said fine position measurement; and

    taking measurements of said home cell at the first user equipment when the first user equipment is close to the home cell.
