requested. This parameter should be provided if the Traffic class is specified as
conversational or streaming. The default value is 0.
<Delivery order>: a numeric parameter that indicates whether the UMTS bearer shall
provide in-sequence SDU delivery or not.
0: No
1: Yes
2: Subscribed value. (default value)
<Maximum SDU size>: a numeric parameter (1,2,3,…) that indicates the maximum
allowed SDU size in octets. If the parameter is set to '0' the subscribed value will be
requested. The default value is 0.
<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+CGEQREQ=…,”5E3”,…). '0E0' (default
value) means subscribed value.
<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+CGEQREQ=…,”5E3”,…). '0E0' (default value) means
subscribed value.
<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
3: Subscribed value (default value)
<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. If the parameter is set to '0' (default value) the subscribed value will be
requested.
<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 the parameter is set to '0' (default value) the subscribed
value will be requested.
0: Subscribed traffic handling priority (default value)
1: Priority level 1
2: Priority level 2
3: Priority level 3
