Section: 11.1 Roaming and Access Restrictions
Content: The principles for conveying roaming and access restriction info for EN-DC are described in TS 36.300[ Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 ]  [2]. For MR-DC with 5GC, SCG (re)selection at the SN is based on roaming and access restriction information in SN. If roaming and access restriction information is not available at the SN, the SN shall consider that there is no restriction for SCG (re)selection. Therefore, the MN needs to convey the latest roaming and access restriction information as received from the Core Network or another NG-RAN node to the SN via XnAP messages.
