The parameter about FACH
ParameterhsDschInactivityTimer = 2
Time after which a connection with low throughput is downswitched from HS-DSCH to CELL_FACH.
inactivityTimer = 30When both the downlink and uplink throughput have been 0 kbps (no data has been transmitted) for this
length of time, a downswitch from CELL_FACH to IDLE state is requested.
The Analysis Of Data
• The timer was modified from 30s to 5s.
• The adjustment was done in TM01R on 5th June.
• According to the chart, the PS DCR made improvement obviously, especially Fach DCR.
The Analysis Of Data• The FACH and PS Drop Rate:
