TRIGGERING DEVICES THAT ARE NOT ATTACHED TO A WIRELESS NETWORK

摘要

Wireless transmit receive units (WTRUs) and methods implemented in WTRUs are described. A method includes monitoring a broadcast channel of a cell of a wireless network for a trigger event while the WTRU is not attached to the wireless network. The WTRU initiates attachment of the WTRU to the wireless network on a condition that the trigger event is detected while the broadcast channel is being monitored. Another method includes monitoring a paging channel of a cell of a wireless network for a trigger event at intervals having a length that is provided to the wireless network while the WTRU is not attached to the wireless network. The WTRU initiates attachment of the WTRU to the wireless network on a condition that the trigger event is detected while the paging channel is being monitored.
