US 10,455,522 B2 · SON accounting for max supported geographical distance

Abstract

A method is disclosed for determining an appropriate transmit power of a cell based on a desired coverage distance, comprising: initializing, at a cell, a cell reference signal transmit power at a high power level; broadcasting a cell signal power measure to require a high signal power level for user devices attempting to connect to the cell; progressively lowering the cell signal power measure at the cell; broadcasting the lowered cell signal power measure; deriving a plurality of user equipment (UE) attach request distances based on a plurality of propagation delay statistics derived from UE attach requests received at the cell; comparing the plurality of UE attach request distances against a maximum distance to obtain a number of UE attach requests received from UEs physically located beyond the maximum distance; and setting the cell reference signal transmit power based on the number of UE attach requests received from beyond the maximum distance, thereby iteratively determining an appropriate cell reference signal transmit power based on the maximum distance and on UE attach requests received at the cell.

A method for determining an appropriate transmit power of a cell based on a desired coverage distance, comprising:

initializing, at the cell, a cell reference signal transmit power at a high power level;
broadcasting a cell signal power measure to require a high signal power level for user devices attempting to connect to the cell;
progressively lowering the cell signal power measure at the cell;
broadcasting lowered cell signal power measure;
deriving a plurality of user equipment (UE) attach request distances based on a plurality of propagation delay statistics derived from UE attach requests received at the cell;
comparing the plurality of the UE attach request distances against a maximum distance to obtain a number of the UE attach requests received from UEs physically located beyond the maximum distance;
and
setting the cell reference signal transmit power based on the number of the UE attach requests received from beyond the maximum distance,
thereby iteratively determining an appropriate cell reference signal transmit power based on the maximum distance and on the UE attach requests received at the cell.

A non-transitory computer-readable medium comprising instructions which, when executed on a self-organizing network coordinating gateway, cause the gateway to perform:

send a configuration message to initialize, at a cell, a cell reference signal transmit power at a high power level;
cause the cell to broadcast a cell signal power measure to require a high signal power level for user devices attempting to connect to the cell;
deriving a plurality of UE attach request distances based on a plurality of propagation delay statistics derived from UE attach requests received at the cell;
comparing the plurality of the UE attach request distances against a maximum distance to obtain a number of the UE attach requests received from UEs physically located beyond the maximum distance;
and
cause the cell to set the cell reference signal transmit power based on the number of the UE attach requests received from beyond the maximum distance,
thereby iteratively determining an appropriate cell reference signal transmit power based on the maximum distance and on the UE attach requests received at the cell.
