<SDU error ratio>
a string parameter that indicates the target value for the fraction of SDUs lost or detected as
erroneous. SDU error ratio is defined only for conforming traffic. The value is specified as ‘mEe’. As an example
a target SDU error ratio of 5•10
-3
would be specified as ‘5E3’ (e.g. AT+CGEQMIN=…,”5E3”,…) (refer 3GPP TS
24.008 [8] subclause 10.5.6.5).
<Residual bit error ratio>
a string parameter that indicates the target value for the undetected bit error ratio
in the delivered SDUs. If no error detection is requested, Residual bit error ratio indicates the bit error ratio in
the delivered SDUs. The value is specified as ‘mEe’. As an example a target residual bit error ratio of 5•10
-3
would be specified as ‘5E3’ (e.g. AT+CGEQMIN=…,”5E3”,…) (refer 3GPP TS 24.008 [8] subclause 10.5.6.5).
<Delivery of erroneous SDUs>
a numeric parameter that indicates whether SDUs detected as erroneous shall
be delivered or not.
0
no
1
yes
2
no detect
Other values are reserved.
<Transfer delay>
a numeric parameter (0,1,2,…) that indicates the targeted time between request to transfer
an SDU at one SAP to its delivery at the other SAP, in milliseconds (refer 3GPP TS 24.008 [8] subclause 10.5.6.5).
<Traffic handling priority>
a numeric parameter (1,2,3,…) that specifies the relative importance for handling of
all SDUs belonging to the UMTS bearer compared to the SDUs of other bearers (refer 3GPP TS 24.008 [8]
subclause 10.5.6.5).
<Source Statistics Descriptor> Supported in R7 P S
a numeric parameter that specifies characteristics of the
source of the submitted SDUs for a PDP context. This parameter should be provided if the Traffic class is
specified as conversational or streaming (refer 3GPP TS 24.008 [8] subclause 10.5.6.5).
0
Characteristics of SDUs is unknown (default value)
1
Characteristics of SDUs corresponds to a speech source
Other values are reserved.
<Signalling Indication> Supported in R7 P S
a numeric parameter used to indicate confirmat content of
submitted SDUs for a PDP context. This parameter should be provided if the Traffic class is specified as
interactive (refer 3GPP TS 24.008 [8] subclause 10.5.6.5).
0
PDP context is not optimized for confirmat (default value)
1
PDP context is optimized for confirmat
