Handover Parameters
Handover aims to ensure communication continuity and good communication quality. Handover in WCDMA system are of the following types: soft handover, softer handover, intra-frequency hard handover, inter-frequency hard handover, inter-RAT hard handover or other types. Handover emerges as the important factor affecting network performance, and handover optimization is also significant in network optimization. Handover parameters are described according to handover classification.
. Intra-Frequency Handover Parameters The common configurable intra-frequency handover parameters are listed here.
. Inter-Frequency Handover Parameters The common configurable inter-frequency handover parameters are listed here.
. Coverage-Based Inter-RAT Handover Management Parameters the common configurable coverage-based inter-RAT handover management parameters are listed here.
. Non Coverage-Based Inter-RAT Handover Management Parameters The common configurable non-coverage-based inter-RAT handover management parameters are listed here.
. Blind Handover Management Parameters The common configurable blind handover management parameters are listed here.
. Cell Selection and Reselection the common configurable cell selection and reselection parameters are listed here.
. Neighbor Management Parameters The configurable neighbor management parameters are listed here
