CSCum88464 - Intelligent graceful PDN disconnection during maintenance-
mode
Feature Changes
Intelligent Graceful PDN Disconnection During Maintenance Mode
When a gateway is in maintenance mode and new-call policy is enabled at a service or APN level, it only rejects new
calls as the rejection is at the demux. For PDNs that have dedicated bearers, even though the APN is in maintenance
mode, since the default bearer is already up, network-initiated dedicated bearers will still be accepted by the gateway
and thus block clearing of all PDNS. CLI has been added to clear the entire PDN when the last VoLTE dedicated bearer
goes down.

Command Changes
clear subscribers
auto-delete
is a new keyword that enables auto deletion when PDN connections that do not have an active voice call
are disconnected.

Notes:
auto-delete
: Clears the PDN/call when the last VoLTE dedicated bearer goes down for P-GW, S-GW,
SAEGW, GGSN, and ePDG.
Calls will not be cleared when one of the calls in a multiple PDN scenario is a VoLTE PDN. When the VoLTE
PDN goes down, all of the other PDNs found for the same IMSI are brought down, which will bring down the
call automatically.
PDN goes down, all of the other PDNs found for the same IMSI are brought down, which will bring down the
call automatically.
max-subscribers
: (existing keyword) The maximum number of subscribers to be cleared.
max_count
must be an integer from 0 through 20000000.
uniform
: (existing keyword) Subscribers will be cleared uniformly.
This assumes that new call policy has been configured on the node to reject any new calls so that these new calls
get directed to an alternate PDN before
clear subscribers
command is executed.
