ABSTRACT
WCDMA is Maturest and the Most popular of 3G in the world. This topic mainly studies
soft handover in WCDMA. Soft handover is one of the key techniques in WCDMA system. It
is the emphasis of radio resource management (RRM) and optimization. The soft handover
algorithm and correlative parameters setting have an immediate effect on the system capacity
and quality of service.So soft handover is very important in WCDMA.
This article has carried on the comprehensive analysis and the research of the WCDMA
system to soft handover, Including cuts its and other contrast, planning and optimized design
of soft handover in network,then from signaling level multianalysis the concrete process
which it realized, the algorithm as well as the parameter establishment influence.
The channel quality and handset's traveling speed is the important affects of the soft
handover. Soft handover technology quality also immediately influence cut success ratio as
well as telephone conversation quality. Therefore renew and enhances the soft handover
technology appears very important unceasingly in the future, this is also an huge goal to many
correspondence workers.
