Method for improving handover performance in a cellular wireless communication system

摘要

Embodiments of the present invention relate to a method for improving handover performance in a cellular wireless communication system, said cellular wireless communication system employing a handover procedure in which a handover preparation for a mobile station is initiated if a channel quality value between a source cell for said mobile station and said mobile station is less than a channel quality threshold value; said method comprising: tuning said channel quality threshold value based on one or more handover performance criteria used in said cellular wireless communication system. Furthermore, the invention also relates to a device for improving handover performance, a computer program, and a computer program product thereof.

1. A method for improving handover performance in a cellular wireless communication system, said cellular wireless communication system employing a handover procedure in which a handover preparation for a mobile station using a processor is initiated if a channel quality value between a source cell for said mobile station and said mobile station is less than a channel quality threshold value; said method comprising:
tuning said channel quality threshold value based on a handover failure rate HOError of said cellular wireless communication system, wherein said channel quality threshold value is increased if the handover failure rate HOError is higher than a handover failure rate target HOError_Target times a first constant k1, and/or said channel quality threshold value is decreased if the handover failure rate HOError is less than a handover failure rate target HOError_Target times a second constant k2.
