Based on the table above, the recommended guidelines are as follows:
If you are going to use timeout idle settings for subscribers/APNs, it is recommended that you configure the
timeout idle parameter in the source context default subscriber to a value that is less than or equal to the lowest
timeout idle for any subscriber/APN.
timeout idle for any subscriber/APN.
If you are going to use timeout absolute settings for subscribers/APNs, it is recommended that you configure the
timeout absolute in the source context default subscriber to a value that is less than or equal to the lowest
timeout idle for any subscriber/APN.
timeout idle for any subscriber/APN.
The FA-service advertise reg-lifetime parameter should be configured to a value less than the source context
default subscriber in non-3GPP networks and APN timeout idle parameter for 3GPP networks.
Failure to follow these recommendations could result in lifetime too long failures when the FA processes the subscriber
profileAPN template and finds an idle timeout that is less than the proposed MIP lifetime in the mobile RRQ.
profileAPN template and finds an idle timeout that is less than the proposed MIP lifetime in the mobile RRQ.
