Enables the operator
to configure different stages of paging in the order of desired execution with
parameters that control the pace, volume, and behavior of a given paging stage.

Syntax
Syntax Description
[ no ] paging-stage level match-criteria { ue-contact-time seconds | all } action { last-n-enb-last-tai max-n-enb value | all-enb-last-tai | all-enb-all-tai } t3413-timeout seconds max-paging-attempts attempts [t3415-timeout t3415_dur ]
no
Remove the
paging-stage from the system.
level
Defines different
levels of paging-stages, each with a different match-criteria and different
action.
level
must be a value 1 through 5.
match-criteria
Specifies the
criteria for selecting a given paging stage.
- ue-contact-time
seconds
- Number of seconds elapsed since the MME last heard
from UE. This time, if set, acts as an upper time limit to consider a given
paging-stage for paging purposes.
seconds
must be a value from 0 through 86400.
- all
- No criteria. Operator can use this match-criteria
for the final paging stage.
action
Defines how the
paging request should be formulated.
- last-n-enb-last-tai max-n-enb
value - Send
paging request to the last known number of eNodeBs (configured using
max-n-enb
value ) and to
the last known TAI.
value must be a
value from 1 through 5.
- all-enb-last-tai - Send paging request to all
eNodeBs and to last known TAI.
- all-enb-all-tai - Send paging request to all
eNodeBs and to all TAIs.
t3413-timeout
seconds
Defines the
time-interval in seconds between paging requests. The MME uses this timer for
retransmission of an S1 Paging request to UE for PS paging.
timeout
must be a value from 0 through 20.
CS triggered S1
Paging requests are transmitted only once by the MME (no retransmission). For a
CS paging to be sent again, another SGs paging request needs to be sent by
MSC/VLR towards MME.
t3415-timeoutt3415_dur
The keyword
t3415-timeout
t3415_dur is used to configure the T3415 paging timeout value. The
t3415_dur is an integer value in the range 1 up to 20 seconds.
max-paging-attempts
attempts
Defines the number
of paging requests to be sent out during this paging-stage.
attempts must be a value from 0 through 5.
Usage Guidelines
Use this command to
configure paging procedure stages, which in turn control the pace, volume, and
behavior of paging for each stage. This command is not enabled by default.
There are no re-tries in a paging stage.
The MME uses the T3413 timer for non-eDRX UEs to re-transmit
paging. For eDRX UEs the MME uses the T3415 timer and on expiry of T3415 timer,
the network aborts the paging procedure.
If a session recovery occurs then the eDRX timer re-starts only
for the remaining time of the total time configured before session recovery.
This is to ensure that the UE and MME are in sync with respect to the paging
occasion.
Refer to the
paging-map
command in the
LTE Policy
Configuration Commands chapter to assign a priority for this paging
profile based on traffic type.
Example
The following configuration example creates a paging-profile in the
lte-policy configuration mode:
paging-stage 1 match-criteria all action all-enb-all-tai t3413-timeout 5 max-paging-attempts 4
