STS: Statistics and Traffic Measurement Subsystem
(STS) is implemented in the BSC (and MSC). It gives statistics about events in
different parts of the system such as cells and equipment. By continuously
supervising the results from STS the operator can obtain a very good overview
of the radio network performance which can help to detect problems early. For
further information,
MRR Measurement Result Recording (MRR) collects
information from the measurement results sent by the BTSs to the BSC.
Information such as RXLEV, RXQUAL etc. is included. The tool is for instance
used for routine supervision or for checking specific cells. MRR is a part of
the Radio Network Optimization (RNO) package in OSS
TEMS Automatic Tems
Automatic is a tool within the TEMS product portfolio, where several special
mobile stations are placed in for instance taxis and buses. The set of mobiles
are supervised centrally and the measurements are sent directly to this center.
TEMS automatic provides the operator with information about subscriber
perceived quality from many parts of the network.
R-PMO The real-time
performance monitor provides real-time statistics in order to receive instant
feedback of performance from sudden changes of the network, either by the
network itself (e.g. hardware faults) or by operator initiated changes (i.e.
parameter, feature or frequency changes). For operator initiated changes,
faster tuning can be achieved. R-PMO also provides a high degree of detailed
information, such as timestamps on events, and flexibility, such as user
defined reports.
NOX Neighbouring Cell List Optimization Expert
(NOX) is a tool meant as a support for the operator for optimization of the
neighbouring cell relations. This is done by collecting and handling data from
measurement reports, handover statistics and general network configurations.
The outcome is suggestions to remove superfluous or add new neighbouring cell
relations. The user can set whether the changes should be implemented
automatically or require an approval by the user.
FOX Frequency Optimization Expert (FOX) measures
for possible interferers in order to find suitable frequencies to define in
cells. FOX supplies the operator with suggestions about frequencies at e.g.
network/hardware expansions or frequency reallocations.
SYROX Synchronized Radio
Network Optimization Expert (SYROX) is a tool intended to support the operator
with planning of parameters that control the frequency hopping for a group of
Synchronized Cells in order to minimize the interference in the network. Apart
from the fact that a group of mutually synchronized cells is required, SYROX
also requires that the optional BSS features FAS (FOX recording mode), and
Flexible MAIO Management are available.
