Improving MOS for GSM in my network

[aguntuk]

Dear experts,
I need help from you. I need to improve MOS in my network. My network is Huawei running BSC6900 where maximum BTSs are 3900 family, few 3012 or 3012A & very little old model 312 BTS. I need to improve MOS for my BSCs actually. Any helpful procedure or document or real life example?
