<SDU error ratio>
String type. 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 s
pecified as “5E3” (e.g.
AT+CGEQREQ=…,”5E3”,…
).
“0E0” Subscribed value
“1E2”
“7E3”
“1E3”
“1E4”
“1E5”
“1E6”
“1E1”
<Residual bit error ratio>
String type. 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+CGEQREQ=…,”5E3”,…
).
“0E0” Subscribed value
“5E2”
“1E2”
“5E3”
“4E3”
“1E3”
“1E4”
“1E5”
“1E6”
“6E8”
<Delivery of erroneous SDUs>
Integer type. Indicates whether SDUs detected as erroneous shall be
delivered or not (refer to
3GPP TS 24.008 subclause 10.5.6.5
).
0 No
1 Yes
2 No detect
3 Subscribed value
<Transfer delay>
Integer type. (0,1,2,…) indicates the targeted time between request to
transfer an SDU at one SAP to its delivery at the other SAP, in
milliseconds. If the parameter is set to „0‟ the subscribed value will be
requested (refer to
3GPP TS 24.008
subclause 10.5.6.5
).
0 Subscribed value
100~150 (value needs to be divisible by 10 without remainder)
200~950 (value needs to be divisible by 50 without remainder)
1000~4000 (value needs to be divisible by 100 without remainder)
<Traffic handling priority>
Integer type. (1,2,3,…) specifies the relative importance for handling of
