PLANNING & OPTIMIZATION RELATIONSHIP
PLANNING NETWORK EVALUATION PATH
1. Basic coverage deployment
2. The first capacity extensions and coverage enhancement deployment (indoor coverage)
3. Intelligent capacity enhancement deployment with strong indoor coverage improvement
4. Base station coverage area splitting/microcellular/dual band deployment, to further improve coverage/capacity/quality

DATA COLLECTION
Data of network plan Network basic information collection
The base of network plan and optimization
The engineering survey data of new sites
Confirm the network plan information.
The Engineering data of the current network
Understand the current network .
The configuration NMS data. Understand the current network
configuration. Collection of various performance reports of the currently deployed network.
Subscribers’ complain The supplement information
showing the network quality.
Let’s begin!

OPTIMIZATION OBJECTIVES
Finding and correcting any existing problems after site implementation and integration.
Meeting the network quality criteria agreed in the contract.
Optimization will be continuous and iterative process of improving overall network quality.
Optimization can not reduce the performance of the rest of the network.
Area of interest is divided in smaller areas called clusters to make optimization and follow up processes easier to handle.
PROPOSED METHODOLOGY
Problem Analysis Conduct Drive testing
Gather statistics Subject to investigage (Faulty TRX, Coverage
overlaps, drop calls, capacity & interference issues) Simulate real-time scenario on TEMS (after DT) Export into MAPInfo to check cell overshoot
coverage, etc Propose solution
EXPECTED OUTCOMES
Good signal coverage at macro and micro sites
Rx Quality level should be good
No interference issue

CONCLUSION
• Satisfactory coverage and quality were found
• In most of the location, additional walk test has been carried out where Operator hasn’t deployed micro layer
• Macro sites should provide coverage to mobile users located in open environment
