Embodiment Construction

[0057] figure 1 A telecommunications network architecture of one implementation of the invention is shown. Such a network includes base stations 13 and mobile terminals 14 . A base station may be responsible for managing one or more cells of the network. In this regard, the invention is not limited in any way. For example, here each radio cell is managed by a base station. The radio coverage areas 11 and 12 are associated with respective base stations 13 .

[0058] Such a network also comprises a radio coverage configuration entity 10 adapted to dynamically and automatically perform an implementation of the radio coverage configuration method of the present invention.

[0059] With regard to the location of this configuration entity 10 in the network, the invention is not limited in any way. For example, in a mobile communication network, this configuration entity may be located in an Operation and Maintenance Center (OMC) or a Radio Network Controller (RNC).

Abstract

A cellular radio communications network comprises a plurality of radio cells. A target radio coverage is associated with each of the radio cells. Each operational radio cell provides an effective radio coverage defined by a transmission power value of said radio cell. A given transmission power value is applied (21) to a given set of radio cells. Next, a radio cell is selected (22). Thereafter, cellular information is obtained (23) relating to a group of radio cells comprising the selected radio cell and neighbouring cells. On the basis of the cellular information, the effective radio coverages of the cells of said group and the respective target radio coverages of the cells of said group are compared (24). If the effective radio coverage of at least one cell of the group of radio cells is inferior to its target radio coverage (25), new transmission power values are applied (26) respectively to radio cells of said group of cells. Next, as appropriate, certain steps are iterated.

Description

technical field [0001] The present invention relates to radio telecommunications networks, and more particularly to planning and optimizing radio coverage in such networks. Background technique [0002] Each of the radio cells making up the cellular telecommunication network provides radio coverage of a targeted geographical area. The combined radio coverage of all said cells defines the overall coverage of the cellular network concerned. [0003] Importantly, this total radio coverage complies with certain constraints. [0004] The first constraint is to provide an effective total radio coverage, ie the radio coverage actually provided by the network, which corresponds to the target radio coverage, ie the coverage corresponding to a predefined geographical area or space. [0005] A second constraint is to avoid interference caused by overlapping cellular radio coverage. If the overlap between two radio coverage areas is too significant, or if the cell density is too high...
