Method for determining in which condition a first base station which is in an energy saving mode has to switch in another operation mode

摘要

The present invention concerns a method for determining, in a wireless cellular telecommunication network, in which condition a first base station which is in an energy saving mode has to switch in an operation mode which enables a mobile terminal to be handled by the first base station and wherein the mobile terminal is currently handled by a second base station. The method comprises the steps of:
obtaining information representative of a path gain between the second base station and the mobile terminal and of a path gain between the first base station and the mobile terminal,determining, from the information representative of the path gains a power of transmission of signal transferred by the first base station which enables the mobile terminal to be handled by the first base station and by the second base station.

主权项

1. A method for determining a transmission power, in a wireless cellular telecommunication network, in which condition a first base station, which is in an energy saving mode, has to switch to a normal operation mode, which would enable a mobile terminal to be handled by the first base station, the mobile terminal being currently handled by a second base station, wherein the method comprises:
operating the first base station in the energy saving mode that does not allow for handling any mobile terminals; operating the second base station in the normal operation mode that allows for handling mobile terminals; obtaining information representative of a path gain between the second base station and the mobile terminal; obtaining information representative of a path gain between the first base station and the mobile terminal; and determining, from the information representative of the path gain between the first base station and the mobile terminal and from the information representative of the path gain between the second base station and the mobile terminal, a power of transmission of a signal transferred by the first base station which would enable the mobile terminal to be handled by the first base station and by the second base station when the first base station is switched from the energy saving mode to the normal operation mode.
