Usage
Use this command to throttle DDNs to allow for the creation of the tunnel and avoid unnecessary DDNs.
For a UE in idle mode, S1U bearers are not established. In such a case, if a downlink packet arrives for the
UE, the S-GW initiates a paging procedure towards the MME. The MME in turn pages the UE in its tracking
area to search for the UE. Upon receiving the paging request, the UE establishes S1U bearers. Too many
DDN requests towards the MME from the S-GW could overload the MME. To reduce this load, the MME
