ranap-cause cause_number
This number identifies the reason the SGSN has detected, from Iu Release messages, for the loss of radio
coverage (LORC). This value is included in the IE messages the SGSN sends to either the GGSN or the
GGSN and the peer SGSN to indicate LORC state. The range of reasons is a part of the set defined by 3GPP
25413.

cause_number
: Must be an integer from 1 to 512.
Default: 46 (MS/UE radio connection lost)
Usage
By defining a cause code, the SGSN knows to detect the LORC state of the mobile from Iu Release messages
it receives for the subscriber. This configuration also instructs the SGSN to include the defined cause code for
the LORC state in the IE portion of various messages sent to the GGSN and optionally the peer SGSN.
This command is one of the two commands required to enable the SGSN to work with the GGSN and,
optionally the peer SGSN, to implement the Overcharging Protection feature (see the SGSN Overview in the
SGSN Administration Guide for feature details. The other command needed to implement the Overcharging
Protection feature is the
