5  GSM Radio Network Optimization

Radio network optimization aims to improve network performance and maximize the benefit of the existing network resources through parameter collection, data analysis, parameter adjustment, and necessary technical means.

From the perspective of carriers, they hope to configure the system rationally, utilize network resources to the maximum, enhance network economic benefit, and reduce operation costs through network optimization. From the perspective of users, they hope to get satisfactory telecommunication services in terms network stability, speech quality, and so on. Therefore, the core task of radio network planning and optimization is to seek a balance among coverage, capacity, and quality based on rational investment and the limited frequency resources, thus achieving the best rate of investment return.

5.1  Network Optimization Procedure

Hereunder details the procedure:

l           Network information acquisition

You are required to confirm the actual engineering parameters and network parameters, survey the local radio environment and hot-traffic spots, and understand customer requirement.

l           Data collection

You are required to collect OMCR traffic statistics data and alarm data; drive test data, and the objective reflection of MS.

l           Data analysis

You are required to analyze network performance, network parameters, and OMCR traffic statistics using network optimization tools.

l           Network tuning

You are required to tune engineering parameters and network functional parameters.

l           Network optimization report

A network optimization report must include optimization measures, fulfilled network performance indexes, and suggestions for network development.
