Improved device for controlling power and load of cells of a mobile network by estimation of temporal evolutions of the measured powers and loads

摘要

A device (D) is dedicated to controlling the transmission power and the reception load in cells (C1-C2) associated with base stations (N1-N2) of a radio access network, for a radio network controller (R1) coupled to the base stations. This device (D) comprises processor means (MT) responsible, in case of reception of a request for setting up/suppressing/reconfiguring a radio link in a cell (Ci), requiring a transmission power or a reception load, for accepting the request i) if the sum of the required transmission power and an estimate of the current value of the transmission power in the cell (C1) is lower than a first threshold or ii) if the sum of the required reception load and an estimate of the current value of the reception load in that cell (C1) is lower than a second threshold. The processor means (MT) estimate the current value of the power or the load in the cell (C1) as a function of an estimate of the temporal evolution of the power or the load induced in the cell (C1) by modifications of link(s) that have occurred since the reception of the latest power and load measurements in this cell (C1), as a function of the type of link and of the configuration of the radio access network imposed by that type of link.
