A lower cache timeout helps to refresh the cache frequently and enables this functionality to quickly adapt to
changes in the network. We recommend the
timeout
value be less than the expected eNodeB flap
frequency; for example, if the eNodeBs connected to the MME are expected to disconnect and reconnect

Default timeout = 5 minutes.
every 10 minutes (due to network issues), then the timeout configuration should be less than 10 minutes.
Default timeout = 5 minutes.
Usage
Both size and timeout must be configured to enable paging cache optimization. The
mme paging cache
command must be entered twice, once for each parameter.
Example
Set the paging cache timeout to match the eNodeB flap frequency of 10 minutes:
mme paging cache timeout 10
