A network sends access control information for receipt by wireless devices that are operating in a suspended connected mode or idle mode under control of the network. The access control information operates to control access to the network by the wireless devices regardless of whether the wireless devices are operating in a suspended connected mode (e.g. in CELL_PCH or URA_PCH paging states) or idle mode. This may be used to inhibit a large number of mobile devices attempting to connect to a network after a particular event (as signaled by the Earthquake and Tsunami Warning System ETWS, for example). Receipt of the ETWS signal by a large number of mobile devices in an idle or suspended connected mode may cause them to attempt to connect to the network simultaneously to transmit buffered information. By restricting access to the network in the above way the risk of overloading a wireless network is reduced. |
