The aim of interoperation optimizing is effective integrating 3G and 2G.Considering the character of the network and testing result

we classified all cells with different scenes.We established equal standard of interoperation parameter and power parameter for different company equipment

ensuring the coherence of parameters and interoperation specification

improving optimizing efficency.Practicing proved that after divided scene 2G/3G interoperation and power parameter optimizer practice

handover successful ratio and drop call ratio improved greatly

and perception of customer improved too.
