•
when the mobile is in READY mode, LLC Data Throughputs are reported at the end of every reporting
period
•
when the mobile is not in READY mode, LLC Data Throughputs are reported only if the number of
transmitted bytes has changed over the reporting period
4.1.3 Total LLC frames transmitted
The Total number of LLC frames transmitted is defined as follows:
•
only I and UI frames are considered
•
only SAPI 3, 5, 9, and 11 are considered (i.e. User SAPIs)
•
in LLC Acknowlegded mode retransmissions are not take into account
It is reported every second, unless it has not changed over the reporting period.

RD
SCREEN (RLC) PARAMETERS
This screen is described in 2.5.3.3.
4.2.1 Retransmitted RLC Block Rate
The Retransmitted RLC Block Rate is computed over a period of
1 second
. It is defined as follows:
Direction Definition
UPLINK Retrans. Block Rate = N
NACKED
/ (N
FIRST TRANS
+ N
NACKED
)
where:
•
N
NACKED
= number of blocks sent in the NACKED state
•
N
FIRST TRANS
= number of blocks that have been transmitted for the 1
st
time
DOWNLINK Retrans. Block Rate = N
LOST
/ N
TOTAL
where:
•
N
LOST
= number of blocks detected as lost. A block or a group of blocks is considered
as lost when the OT detects a gap in the block sequence
•
N
TOTAL
= number of blocks that have been supposedly sent. It is estimated based on
the Sequence Number of the latest received block. As a consequence it does not
include retransmitted blocks.
The Retransmitted RLC Block Rate is filtered according to the following criteria:
•
in the Uplink: it is reported only if (N
FIRST TRANS
+ N
NACKED
) has changed over the reporting period.
•
in the Downlink: it is reported only if N
TOTAL
has changed over the reporting period.
4.2.2 RLC/MAC Data throughput traces
The RLC/MAC Data throughput takes into account RLC/MAC Data blocks only, including retransmissions
and header parts. It is computed over a period of
1 second
and reported according to the following criteria:
•
when the mobile is in READY mode, RLC/MAC Data Throughputs are reported at the end of every
reporting period
