By adjusting the state transition parameters, the low data
improve HSDPA transmission requirements of HSDPA UEs are handed over to
1 State transfer parameter avaliable Resource the FACH state, so that the HSDPA users decreases,FACH users
increase, improving H user available resource.
CM time improve HSDPA Reduce CM timer,So that reduce CM meature time.UE can little
2 parameter
optimization throughput stay in CM state.That ue can get throughput
Cancle CM and H survive,So that ue can not make CM in H
H And CM improve HSDPA statue.Because the coverage is worse when ue descide to
3 Function
survival throughput CM.Even in H Statue the throughput is low.So that may decrease
average throughput.
improve HSDPA reduce H2D trasnfer UE throughput,this make R99 use less
5 H2D initial rate parameter throughput resource.That H user can use more resource.
DPCH PILOT PO parameter improve HSDPA By reduce DPCH power,So that reduce NonH power.Make H
6
Optimization avaliable power service can get more power.
DPCH TPC PO improve HSDPA By reduce DPCH power,So that reduce NonH power.Make H
7 Optimization parameter avaliable power service can get more power.
MAC-D improve HSDPA Change the Mac-d scheduling frequency from 2 is changed to 5
8 parameter
Schedule throughput times every 10ms, saving rate upsizing time
R99 GBR improve HSDPA Decrease R99 permit Guaranteed rate,So that reduce r99
11 parameter avaliable
optimization Resource Minimum consumption resources.That H can get more resource
Avoid RRC signaling may be long-term hanging on net. Impact:
