sgs-service sgs_svc_name
Specifies the SGs service to which the VLR belongs.
sgs_svc_name
specifies the name of a pre-configured SGs service. For more information on the SGs
service, refer to the
sgs-service

over which all qualifying subscribers will be offloaded.

must be an integer from 0 to 3000.
A value of 0 enables only Passive VLR Offloading, where the MME marks all affected sessions with the
“VLR Offload” flag. During the next UE activity, the MME requires each UE to perform a combined
TAU/LAU. This flag is not affected by the removal of the “offload” state by the operator. Even though the
VLR state may later change from “offloaded’ to “not-offloaded”, the subscriber’s state will not change to
“not-offloaded”.
A value of 1-3000 enables Active VLR Offloading and Passive VLR Offloading. The MME splits this time-
duration into n intervals, 5 seconds apart. A maximum of 50 subscribers will be actively detached per
interval. For example, a setting of 120 minutes with 60000 subscribers would process all subscribers in 100
minutes. Any subscribers remaining at the expiry of the time-duration will not be detached.
