A cellular communication network is described wherein the power of the pilot channel transmitted by the base station is decreased when the uplink interference in its cell area increases above a threshold value. As a result the mobile terminals at the edge of the cell area are triggered to reselect to another base station and the number of call drops and failed call set-ups is reduced.

Pilot channel transmission in a cellular communication network

The invention refers to a method for dynamically setting the radiation pattern of an antenna of a base station connected to User Equipments in a cellular telecommunications network by obtaining data of the positions of User Equipments located under coverage of the base station during a predetermined period of time; statistically treating said data of the positions of User Equipments to obtain at least one statistical parameter of said data, and changing the radiation pattern of the antenna depending on the result of comparing said at least one statistical parameter with a pre-established value.
