Provide Latest Engineering Parameters and Neighbor List for RF Optimization Deeply Analysis;

Support from Wireless part to Loop and troubleshoot For The Silence / Mute calls ;

Provide Wireless & Transmission Network Structure For Deeply Audit;

In Order To Make Audit For Relating Parameters and Timers, We need Orange CI Provide Rela

Timers Setting Form Wireless Part;

Co-BCCH Strategy & Inter-HO Parameter Setting Strategy Can Be Discussed Together;

Frequency Re-planning Should Be Considered For The Noise Call Issue;
