Mobility Restrictions restrict mobility handling or service access of a UE.
–The Mobility Restriction functionality is provided by
the UE (only for mobility restriction categories provided to the UE),
the radio access network and
the core network.
Unless otherwise stated, Mobility Restrictions only apply to 3GPP access, they do not apply to non-3GPP access.
–Service Area restrictions and handling of Forbidden Areas for CM-IDLE state and, for CM-CONNECTED state when
–in RRC Inactive state are executed by the UE based on information received from the core network.
–Mobility Restrictions for CM-CONNECTED state when in RRC-Connected state are executed by the radio access network and the core network.
–In CM-CONNECTED state, the core network provides Mobility Restrictions to the radio access network within Mobility Restriction List.'
Mobility Restrictions consists of RAT restriction, Forbidden Area, Service Are Restrictions and Core Network type restriction as follows:
RAT restriction:
–Defines the 3GPP Radio Access Technology(ies), a UE is not allowed to access in a PLMN. In a restricted RAT a UE based on subscription is not permitted access to the network for this PLMN.
–For CM-CONNECTED state,
owhen radio access network determines target RAT and target PLMN during Handover procedure, it should take per PLMN RAT restriction into consideration.
The RAT restriction is enforced in the network, and not provided to the UE.
