Method for measuring home cell in mobile communication system
First Claim
1. In a mobile telecommunications system comprising:
- a network including a plurality of base stations for defining communications cells; and
first and second user equipments for communicating with the network, the plurality of base stations including at least one home base station defining a home cell associated with the first user equipment and not with the second user equipment, the home cell overlapping in coverage with a communications cell usable by both the first and second user equipments, 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 the 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 the fine position measurement; and
taking measurements of the home cell at the first user equipment when the first user equipment is close to the home cell.

Abstract
Disclosed is method for measuring a home cell 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, the method including 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; 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.
