Idle Timer Handling on UPF Call Flow
This section describes the call flow when the idle timer is received in the Create Session Request on the UPF.

Description |
---|---|
1 |
If the value of idle_timeout_sec is greater than zero, the timer is started on UPF with granularity of one second. Else, idle timeout is disabled. |
2 |
The timer timeouts every second. Checks if the difference in current time and last packet received is greater than idle_timeout_sec or not. If the time difference is greater than idle_timeout_sec, then UP sends the Sx Session Report Request with Report Type = UPIR (Inactivity Report) to CP (cnSGW-C). |
