Timer Values and Recommendations

The following table shows values that would be populated under a number of different configured scenarios.

Table 16.

Sample Call Flow Timer Scenarios

Scenario

Mobile Sub. MIP Lifetime

600

APN Template Timeout Absolute

300

APN Template Timeout Idle

300

FA-Service Advertise Reg-Lifetime

400

Mobile Sub. Profile AAA Context Timeout idle

500

HA-Service MIP Lifetime

400

Agent Advertisement Reg-Lifetime

295

Mobile Sub. MIP RRQ requested lifetime

295

FA MIP RRP Lifetime

295

FA MIP RRP

success

Lifetime too long

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.

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.

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.
