Feature Description

Without the perform-imsi-detach option the SGs SCTP association with respect to the peer-id will be aborted and corresponding SCTP data, timers are cleared and stopped, then the SCTP re-association will be triggered.

When the perform-imsi-detach and without detach-rate options are executed, the SGs SCTP association with respect to the peer-id will be aborted. UEs that are associated with the VLR will be detached at default-rate of 50 detaches/cycle and SGs-Reset-Indication will be send once the VLR re-association is up.

When the perform-imsi-detach and detach-rate options are executed, the SGs SCTP association with respect to the peer-id will be aborted. UEs that are associated with the VLR will be detached at the specified-rate and SGs-Reset-Indication will be send once the VLR re-association is up.


Important

Increasing the detach rate might increase MME Manager load.
