1. A communication control method comprising:
broadcasting, by a cell belonging to a Non-Public Network (NPN), a system information block comprising an NPN identifier identifying the NPN;
receiving, by an Integrated Access and Backhaul (IAB) node configured to perform relaying between a user equipment and a network, the system information block from the cell, the IAB node including a Distributed Unit (DU) and a Mobile Terminal (MT); and
determining, by the IAB node, whether an access from the IAB node to the cell is permitted, based on the system information block, wherein
the system information block further comprises an NPN identifier information list,
the NPN identifier information list comprises the NPN identifier and the IAB node support information associated with the NPN identifier,
the IAB node support information indicates that the cell supports the IAB node configured to perform relaying between the user equipment and the network, and
the determining, by the IAB node, comprises determining whether the access is permitted, based on the IAB node support information comprised in the NPN identifier information list.
