Case 5 : Half Rate
To decrease TCH Blocking, we implemented parameter DTHNAMR for some cells which has
high TCH BlockingAfter implementation TCH Blocking is decrease and some cells is maintain.

found some high SD Blocking due to lack resources and need to re-dimensioning SDCCH
After implementation SDCCH is decrease as well
Case 6 : SD Re-dimensioning

Defines what kind of on-demand PDCHs are possible to pre-empt for the CStraffic:
Default: 0
0 No PDCHs protected1 PDCHs used for DTM protected2 PDCHS used for Streaming protected3 PDCHs used for DTM and PDCHs used for Streaming protected4 Essential PDCHs protected
5 Essential PDCHs and PDCHs used for DTM protected6 Essential PDCHs and PDCHs used for Streaming protected7 Essential PDCHs and PDCHs used for DTM and PDCHs used for Streamingprotected8 Busy PDCHs protected
Essential PDCH: A Packet Data Channel (PDCH) used in a TBF to carry the Timing
Advance Information.
Case 7 : PDCH Preemption

PDCH Pre-Emption change from 0 to 4 will be implemented to cells which has low TCH
blocking to improve TBF completion

FPDCH re-dimensioning for cells that has low TBF Establishment and low TCH Blocking
After implementation TBF Establishment and data payload is increase.
