When a major earthquake struck Japan most ofthe mobile network operators(MNOs) enforced originating call control and this made users frustrated due to severe inability to make phone calls.This paper proposes a solution for migrating UE registration between call session control function (CSCF) servers in IP Multimedia Subsystem(IMS).This allows the MNOs to rapidly distribute the processing workload of the CSCF servers in the case where the MNOs newly obtain serverresources.A key is adaptively controlling of the number of UEs migrated between servers so as to avoid excessive increase inthe IMS processing workload.This is done by monitoring processing workload of SIP servers in IMS.
