Configuring the 3GPP Timers
To configure the GPP timers, use the following configuration:
config
amf-global
call-control-policy policy_name
timers timer_type { retry retry_count | value timeout_value }
end
NOTES:
-
timers timer_type retry retry_count —Specify the retry count.
-
timers timer_type value timeout_value —Specify the timeout value.
For the timer_type, refer to the following table.
Timer |
Retry Count or Attempt Count |
Timeout Value |
---|---|---|
tidt |
Not Applicable |
Must be an integer in the range of 0–35712000 seconds. The default value is 3480 seconds. |
ho-supervisory |
Not Applicable |
Must be an integer in the range of 100–10000 mill seconds. The default value is 500 milliseconds. |
tpurge |
Not Applicable |
Must be an integer in the range of 0–35712000 seconds. The default value is 86400. |
t3346 |
Not Applicable |
Must be an integer in the range of 1–11160 seconds. The default value is 900 seconds. While processing the t3346 timer towards UE, AMF adds a random offset to the configured timer value. This random offset is based on the configured timer value. If timer value is:
Maximum value of the recomputed timer value is 11160 seconds. |
t3502 |
Not Applicable |
Must be an integer in the range of 0–35712000 seconds. The default value is 720 seconds. |
t3512 |
Not Applicable |
Must be an integer in the range of 0–35712000 seconds. The default value is 3240 seconds. |
t3513 |
This parameter defines the number of paging attempts. Must be an integer in the range of 1–5. The default value is 2. |
Must be an integer in the range of 1–10 seconds. The default value is 5 seconds. |
t3522 |
This parameter defines the number of paging retries. Must be an integer in the range of 0–5. The default value is 4. |
Must be an integer in the range of 0–30 seconds. The default value is 6 seconds. |
t3550 |
This parameter defines the number of paging retries. Must be an integer in the range of 0–5. The default value is 4. |
Must be an integer in the range of 0–30 seconds. The default value is 6 seconds. |
t3555 |
This parameter defines the number of paging retries. Must be an integer in the range of 0–5. The default value is 4. |
Must be an integer in the range of 0–30 seconds. The default value is 6 seconds. |
t3560 |
This parameter defines the number of paging retries. Must be an integer in the range of 0–5. The default value is 4. |
Must be an integer in the range of 0–30 seconds. The default value is 6 seconds. |
t3570 |
This parameter defines the number of paging retries. Must be an integer in the range of 0–5. The default value is 4. |
Must be an integer in the range of 0–30 seconds. The default value is 6 seconds. |
To configure the t3513 timer, use the following configuration:
config
amf-global
call-control-policy policy_name
timers t3513 { attempts paging_attemps_count | value timeout_value }
end
NOTES:
-
timers t3513 attempts paging_attemps_count —Specify the number of paging attempts.
-
timers t3513 value timeout_value —Specify the t3513 timeout value.
For the t3513 timer configuration values, refer to the 3GPP Timers and Values table.
