Methods of and apparatuses for cell-differentiated handover in a mobile communications systems

摘要

The present invention relates to handover procedures in a cellular communications system ( 1 ). The cells ( 10 - 70 ) of the system ( 1 ) are divided into multiple handover-related classes based on their respective radio coverage characteristics. Each such cell class is then associated with a unique handover parameter or a unique set of parameters that are used in handover procedures involving the cells ( 10 - 70 ). The parameter values are adapted for the radio coverage characteristics of each cell class in order to generate a suitable handover region size of the cells ( 10 - 70 ). The handover parameters are used together with user equipment-assisted signal quality measurements for triggering the handover procedures.
