Abstract
An access network node (12) is connected to a first core network (15) of a first Public Land Mobile Network (PLMN) (10) and to a second core network (25) of a second PLMN (20). In response to a disaster condition being applied to an area to which a cell of the access network node (12) belongs or in response to an increase in load on the first core network, the access network node (12) restricts access to the cell from User Equipments (UEs) (32) using the second core network (25) and prioritizes access to the cell from UEs (31) using the first core network (15). This allows, for example, users of one PLMN to have priority over users of another PLMN to use a shared radio access network when necessary, such as in the event of a disaster.
