end
Notes:
radio-cause
: A maximum of 16 BSSGP protocol radio cause codes can be defined per group. Note that under
each cause code group the maximum number of cause codes (ranap+bssgp+s1ap) that can be supported is 16.
cause_code
: Enter an integer from 0 to 255 to identify a BSSGP protocol radio cause code, as defined in the
Radio Cause section of the 3GPP TS 48.028 specification.
no
: When included with the command, the specified cause code is deleted from the group. If all cause codes are
deleted from the group then the group is automatically deleted.
Important:
The SGSN does not support Enhanced Radio Status functionality; therefore, the SGSN treats cause
code values 0x03 and 0x04 as “Radio contact lost with MS”. Therefore, the valid configurable cause codes values are 0,
1, and 2.
1, and 2.
cause
This new command, in the new RANAP Cause Code configuration mode, enables the operator to define multiple cause
codes for the 3G service so that
codes for the 3G service so that
if the RANAP cause code configured by the operator matches with the cause received in the Iu-Release Request
message, and
if the Subscriber Overcharging Protection feature is enabled for 3G service in the SGSN-Service configuration
(see command information above),
then the S4-SGSN includes ARRL (i.e., Abnormal Release of Radio Link) bit in Release Access Bearer Request
message initiated on Iu-Release.
