stop
Specifies that the offload state should no longer be set for the specified the VLR.
-noconfirm
Indicates that the command is to execute without additional prompt and confirmation from the user.
Usage
This command enables the MME to preemptively move subscribers away from a VLR which is scheduled to
be put in maintenance mode. When this offload command is set on the MME, all sessions matching this VLR
are marked with an “offload” flag. If the time-duration keyword is set to 1-3000, sessions are also detached
and required to reattach.
The behavior of SGs with respect to “Location Updates” towards the MSC is similar to the behavior when the
“VLR Reliable” flag is set to “false”. In other words, for offloaded subscribers, normal Combined TAUs
(without IMSI Attach) and periodic TAUs will trigger a LU towards the MSC.
When issuing the command, the MME notifies the operator if this is the last available VLR in a pool.
More than one VLR may be offloaded at the same time.
VLR Offloading and MME offloading cannot be performed at the same time.
