This document discusses comprehensive network optimization. Comprehensive optimization involves maximizing desired factors and minimizing undesired ones within constraints, with a large scope that covers more key performance indicators, alarm monitoring, parameter monitoring, and predictions. It emphasizes the need to correlate different data sources, like statistics, subscriber measurements, alarms, and parameter changes, to better measure customer experience and satisfaction. Achieving comprehensive optimization requires developing a database that can correlate this network and customer data using various tools to continuously monitor performance and identify potential problems.

The principal difficulty in managing the complex wireless network is that there’s no real-corellations measure
of the desired end-result, customer satisfaction. That’s like trying to do speed without a speedometer.

Wrap Up
• The for optimisation or achieving better
network quality is to develop a good database which
allows an operator to correlate network statistics,
subsriber experiance, call detail records, alarms,
external units, cell parameters, etc. using a single
platform or platforms that can talk each other.
Furthermore, it is also important for such a system to
prioritise and alert the operator when potential
problems are detected in the network. Continuous
monitoring, ceaseless curiosity about what useful
information the network can yield, and dynamic
performance analysis infrastructures are a must for
operators to improve network quality. This is also valid
for 2.5G, 3G or any other G’s.
