paging-failure-action downlink-data-lockout-timer
seconds [ repeat number_repeats
]
Default: 1000 seconds.
Enables and configures the downlink data lockout timer, for the SGSN services, to reduce the frequency of
mobile-initiated keep alive messages.

seconds
set the number of seconds before timer expire, range of 0 to 10000.
repeat number_repeats
optionally sets the number of times (1 to 10) that the timer restarts after paging
failure. Note: If repeat is not configured then paging proceeds endlessly until the MR timer expires.
[ default | no ] gmm paging-failure-action
disables the downlink data lockout timer.
perform-identity-on-auth-failure
Default: Enabled
Configures the SGSN service to perform an identity check to ascertain the IMSI after an authentication
failure on a PTMSI-based message.
Configures the SGSN service to perform an identity check to ascertain the IMSI after an authentication
failure on a PTMSI-based message.
purge-timeout
minutes
Default: 10080 (7 days)
The purge timer defines the MM-context lifetime, part of the MM-context procedure on the network side. The
configured value sets the duration (number of minutes) the SGSN holds the detached subscriber’s MM-
context profile. If the subscriber does not reattach to the SGSN during this time, then the SGSN purges this
detached subscriber’s MM-context information from its database and sends a MAP purge request towards the
HLR to indicate that the subscribers profile is gracefully purged from SGSN’s database.

minutes
must be an integer from 1 through 20160.
trau-timeout trau_dur
This timer is available in releases 9.0 and higher.
Default: 30
Specifies the number of seconds the “old” 3G SGSN waits to purge the MS’s data. This timer is started by the
“old” SGSN after completion of the inter-SGSN RAU.

trau_dur
: Must be an integer from 5 to 60.
Usage
Repeat this command as needed to configure multiple parameters for GPRS mobility management in a
UMTS network. This command provides the configuration of timers for mobility procedures and retries for
different messages. GMM layer is defined in the 3GPP TS 24.008 (Release 7).
