Entering the above command sequence results in the following prompt:
cause cause_code no cause cause_code
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.
Enter an integer from 1 to 512 to identify a cause code. Valid options are listed in 3GPP TS 25.413 v11.5.0 (or later version), subsection on Cause in section for Radio Network Layer Related IEs.
A maximum of 16 RANAP protocol 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.
Benefit of using the cause code group for 3G service is
- 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,
- then the S4-SGSN includes ARRL (i.e., Abnormal Release of Radio Link) bit in Release Access Bearer Request message initiated on Iu-Release.
