Abstract: An access point to a restricted-access cell of a cellular network detects at least one cell of the cellular network in the vicinity of the cell in which it is located. It sends a server of the cellular network an identifier (RAC1) of the restricted-access cell, an identifier of the cell(s) detected, and an identifier of at least one user (U1) authorized to access the restricted-access cell. On reception of this information, the server stores it in a database (26) and can therefore send a mobile terminal (10) of said user (U1) the identifier (RAC1) of the restricted-access cell it is authorized to access. This identifier can be sent if the server detects that the mobile terminal (10) is in the vicinity of the restricted-access cell and/or periodically and/or in the event of a change to the information stored in the database (26) of the server.

Abstract: A cellular radio communications network includes a plurality of radio cells. A target radio coverage is associated with each radio cell. 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 particular set of radio cells. A radio cell is then selected (22). Thereafter, cellular information is obtained (23) relating to a group of radio cells comprising the selected radio cell and neighboring 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 less than its target radio coverage (25), respective new transmission power values are applied (26) to radio cells of said group of cells. Certain steps are then repeated, as appropriate.
