short description for the RRC_MEASUREMENT_REPORT

This is another measurement factor to determine the bit rate adaptation. For this measurement two events (4A and 4B) are reported.RRC traffic volume measurement event will be used to monitor the UE radio link control buffer payload on dedicated channels. The RNC will set up the traffic volume measurement for the bit rate adaptation and channel type switching at PS interactive/background RAB setup.A single RRC measurement control message is used to configure the events for bit rate adaptation and the FACH to DCH trigger is as follows:

Event 4A on DCH triggers UL BRA rate increase.
When the UE detects RLC volume overflow, it is reported by RRC measurement
report event 4A to RNC. After the BRA activation the rate is increased.
Event 4B on DCH triggers UL BRA rate decrease
When the UE detects RLC volume underflow, it is reported by RRC measurement
report event 4B to RNC. The data rate will be decreased.
Event 4B on RACH triggers CTS from FACH to DCH
In RACH status the common channel is switched to dedicated channel.
The traffic volume measurements will be valid for the duration of the PS interactive
/background call except in DCH INACTIVE state.

Now I want to know what's the report threshold of 4A and 4B, Can they be the same ? cause I have a case and the threshold is the same but "Time to trigger" is diffrent.

BTW there are some information about different Event
