Abstract
This slide describes the principles and tools of GSM
neighboring cell optimization. Neighboring cell optimization is
intended to avoid missing and redundant neighboring cells,
which improves the GSM network performance.

Neighboring Cell Optimization Schemes
Neighboring cell optimization should be conducted throughout
frequency replanning. The detailed schemes are as follows:
Disable redundant neighboring cells to save the space in the BA2 table
and improve the measurement efficiency of Cellopt.
Add missing neighboring cells to improve the handover success rate
and reduce the call drop rate.

A new Nastar platform is
deployed onsite.
Requirement Scheme Advantage and Disadvantage
1. NastarV600R002 and later
versions
2. BSC6000 V900R008C01 and later
versions
3. M2000 V200R008C01SPC010 and
later versions
The new Nastar platform
automatically outputs
suggestions on neighboring cell
optimization according to MR
data.
Advantage: Based on the actual traffic interference situation of the
existing network, the output suggestions is accurate and reliable.
Disadvantage: The NE mapping version is restricted.
Disable redundant
neighboring cells
through measurement
of outgoing/incoming
cell handovers of
.No new Nastar
platform is
deployed onsite.
Early stage of
frequency
replanning
Old Nastar platform
1. Manually check all cells to
determine whether missing
neighboring cells exist;
2. Output suggestions on
neighboring cell planning
according to location relation todetect missing neighboring cells.
Advantage: An old Nastar platform is stand-alone and thus is easy
to install. The software is available at http://support.huawei.com and
can be used with a license applied for from Liu Fengzhen
(employee ID: 00126279).
Disadvantage: Only longitudes and latitudes are considered.
Therefore, the old Nastar platform is not as accurate and reliable asthe new one.
U_Net license
Conduct emulation prediction
according to input RF
parameters, antenna heights,
azimuths, and tilts, and plan
neighbor relation of each cell. In
this way, missing neighboring
cells are detected.
Advantage: Suggestions on neighboring cell planning can be
conveniently output through emulation.
Disadvantages: 1. It is hard to obtain the license of the U_Net
onsite because the license must be purchased.
2. It is hard to control the planning results that rely on the accuracy
of engineering parameters.
Drive test tool
Determine whether missing
neighboring cells exist according
to abnormal events during DT
tests.
Advantage: Missing neighboring cells can be accurately and
reliably detected according to call situations.
Disadvantage: Only routing situations can be indicated.
1. Cellopt license
2. BSC6000 V900R008C01 and later
versionsThe Cellopt automatically
outputs suggestions on
neighboring cell optimization
according to MR data.
Advantage: Based on the actual traffic interference situation of theexisting network, the output suggestions are accurate and reliable.
Disadvantage: 1. As software for frequency replanning, the Cellopt
is used only at sites where frequency replanning is conducted
because its license is expensive.
2. MR data needs to be transmitted to the frequency replanning
center onsite. The center then outputs optimization suggestions.
Large amount of MR data leads to interworking troubles.
Late stage of
frequency
replanning
1. Cellopt license
2. BSC6000 V900R008C01 and later
versions
Advantage: The frequency replanning center outputs suggestions
on neighboring cell optimization and frequency schemes at the
same time to reduce onsite workload.
