US 2015/0031360 A1 · METHOD AND DEVICE FOR LOAD BALANCING IN WIRELESS COMMUNICATION SYSTEM

Abstract

A method for a load balancing using statistical information in a base station of a wireless communication system is provided. The method includes measuring a load of at least one cell managed by the base station; exchanging load information of the measured cell with at least one neighboring base station; determining at least one Mobility Load Balancing (MLB) application candidate cell in which a Cell Individual Offset (CIO) change is necessary using the load information; determining at least one MLB application target cell in the at least one MLB application candidate cell; performing a CIO change procedure with the at least one MLB application target cell; selecting at least one User Equipment (UE) to notify a CIO change; and notifying the selected at least one UE of the CIO change.

Dependent claims

A method for a load balancing in a wireless communication system, the method comprising:

monitoring loads of a source cell and at least one neighboring cell;
determining at least one candidate neighboring cell to perform handover related parameter adaptation for load balancing in consideration of at least one of an overload condition of the source cell, a load ratio condition of the source cell and the neighboring cell, or a load difference condition between the source cell and the neighboring cell;
determining at least one target neighboring cell from the at least one candidate neighboring cell using a function for determining a priority of neighboring cells based on handover related statistics;
and
adapting a handover related parameter value for the load balancing for the at least one target neighboring cell.
