Section: 4.3.5.7 Mobility Restrictions
Content: Mobility Restrictions comprises the functions for restrictions to mobility handling of a UE in E-UTRAN access. The Mobility Restriction functionality is provided by the UE, the radio access network and the core network. Mobility Restriction functionality in state ECM-IDLE is executed in UE based on information received from the core network. Mobility Restriction functionality in state ECM-CONNECTED is executed in the radio network and the core network. In state ECM-CONNECTED, the core network provides the radio network with a Handover Restriction List. The Handover Restriction List specifies roaming, area and access restrictions. If roaming restriction to GERAN or UTRAN access needs to be enforced, a MME that is connected to eNodeBs that may handover or invoke release with redirection to UTRAN or GERAN is configured with a list of HPLMN IDs that are permitted to access GERAN or UTRAN unless restricted by the UE individual access restriction information received from HSS.
