4. ANNEX: GPRS QOS PARAMETERS DEFINITION
This Annex defines and explains how some GPRS variables displayed in screens of the GPRS Info menu
of calculated and refreshed.
4.1 DATA TRANSFER 2ND SCREEN (LLC) PARAMETERS
This screen is described in 2.5.3.2.
4.1.1 Retransmitted LLC Frame Rate
The Retransmitted LLC Frame Rate is computed over a period of 1 second. It is defined as follows:
Direction Definition
UPLINK Retrans. Frame Rate = NRETRANS / NTOTAL
where:
• N
RETRANS = number of frames that are not sent for the 1st time
• N
TOTAL = total number of transmitted frames
DOWNLINK Retrans. Block Rate = NLOST / NTOTAL
where:
• N
LOST = number of frames detected as lost. A frame or a group of frames is considered
as lost when the OT detects a gap in the frame sequence
• N
TOTAL = number of frames that have been supposedly sent. It is estimated based on
the Sequence Number of the latest received frame. As a consequence it does not
include retransmitted frames.
The Retransmitted LLC Frame Rate is filtered according to the following criteria:
• it is reported only if at least one LLC SAPI is in Acknowledged mode
• it is reported only if NTOTAL has changed over the reporting period.
4.1.2 LLC Data throughput
The LLC Data throughput traces are focused on the capacity that is offered by the LLC layer to upper layer
in the User plane. As a consequence the LLC Data throughputs are 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
• LLC header parts are not taken into account
The LLC throughputs are computed over a period of 1 second and reported according to the following
criteria:

• 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.
4.2 DATA TRANSFER 3RD 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 = NNACKED / (NFIRST TRANS + NNACKED)
where:
• N
NACKED = number of blocks sent in the NACKED state
• N
FIRST TRANS = number of blocks that have been transmitted for the 1st time
DOWNLINK Retrans. Block Rate = NLOST / NTOTAL
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 (NFIRST TRANS + NNACKED) has changed over the reporting period.
• in the Downlink: it is reported only if NTOTAL 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

• when the mobile is not in READY mode, RLC/MAC Data Throughputs are reported only if the number
of transmitted bytes has changed over the reporting period
4.2.3 Total RLC blocks transmitted
The Total number of RLC blocks transmitted is defined as follows:
• only DATA blocks are take into account
• all received or sent blocks are considered, including those blocks that are retransmitted in NACKED or
PENDING ACK state
It is reported every second, unless it has not changed over the reporting period.
4.3 MEASUREMENT INFO PARAMETER
This screen is defined in 2.5.5.
The Downlink RLC BLER is computed over a period of 1 second. It is defined as follows :
BLER = NERRORED / NTOTAL
where:
• N
ERRORED = number of data blocks received with a bad CRC and a TFI corresponding to the current
downlink TFI allocated to the mobile
• N
TOTAL = total number of data blocks received with a TFI corresponding to the current downlink TFI
allocated to the mobile
NOTE: the received RLC/MAC blocks are filtered according to the PAYLOAD TYPE and TFI fields of their
RLC/MAC headers. Those fields can be affected by transmission errors, so the two parameters above
(NERRORED and NTOTAL) can only be estimated. As a consequence the reported value must be considered
as an estimation of the Block Error Rate of the radio link between the network and that particular mobile.
