The present annex specifies additional requirements for GMM and EMM in the MS for the support of terminating access domain selection for voice calls or voice sessions by the network.

Support of these mobility management procedures can be configured in the MS by a setting. Whether the mobility management for IMS voice termination setting is stored in the IMS management object as defined in 3GPP TS 24.167 [134] (see the "Mobility Management for IMS Voice Termination" leaf) or in an alternative way in the ME is an implementation option. If this setting is missing, then mobility management for IMS voice termination is disabled.
