<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. +CGEQNEG:…,”5E3”,…).
<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. +CGEQNEG:…,”5E3”,…)
<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
<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.
If a value is omitted for a particular class then the value is considered to be
unspecified.
