OC-Validity-Duration  AVP ( 625 )

he OC-Validity-Duration AVP indicates in seconds the validity time of the overload report. The number of seconds is measured after reception of the first OC-OLR AVP with a given value of OC-Sequence-Number AVP. The default value for the OC-Validity-Duration AVP is 30 seconds. When the OC-Validity-Duration AVP is not present in the OC-OLR AVP, the default value applies. The maximum value for the OC-Validity-Duration AVP is 86,400 seconds (24 hours). If the value received in the OC-Validity-Duration is greater than the maximum value, then the default value applies.
