Layer 2 - CPE Uplink Congestion Control
Field Name Values Description
Avg Queue Size Weight
(%)
100.0
For the uplink, this value - expressed as a percentage -
indicates how much the current queue size contributes to
the calculation of average queue size. The average queue
size is used by the BTS Resource Management software
to determine how many resources (Code Channels) to
give a CPE. The greater the weight, the greater influence
the current queue size has on the average queue size. The
lower the weight, the more the average queue size is an
actual average of the current queue size over time.
Max Queue Size (KB)
512
For the uplink, the maximum queue size for each priority
queue (high, low, voice). Once the queue is full (at Min
Drop Threshold) all packets are dropped.
Min to Max Drop
Probability (%)
10 For the uplink, the probability of a packet being dropped
when the Min threshold has been reached. The higher this
number, the more likely a packet will be dropped
between the Min Threshold and Max Threshold. Note:
All packets are dropped at the Max Threshold.
Realtime Min Drop
Threshold (%)
100 For the uplink, the minimum queue size in which voice
priority packets are considered for being dropped. For
example, if set to 10% once the queue size reaches 11%
or more, voice priority packets may be dropped. The Max
Drop Probability field determines if a packet is dropped
once the Min Threshold is exceeded.
High Priority Min Drop
Threshold (%)
100 For the uplink, the minimum queue size in which high
priority packets are considered for being dropped. For
example, if set to 10% once the queue size reaches 11%
or more, high priority packets may be dropped. The Max
Drop Probability field determines if a packet is dropped
once the Min Threshold is exceeded.
Low Priority Min Drop
Threshold (%)
100 For the uplink, the minimum queue size in which low
priority packets are considered for being dropped. For
example, if set to 10% once the queue size reaches 11%
or more, low priority packets may be dropped. The Max
Drop Probability field determines if a packet is dropped
once the Min Threshold is exceeded.
