Abstract

In a wireless communication system comprising at least one wireless transmit/receive unit (WTRU) and a trusted entity, a method and apparatus for processing data during an event, includes storing data in a memory of the WTRU. The stored data is classified in the memory of the WTRU. The WTRU detects an event and transmits a notification signal to the trusted entity in response to the event detected. The trusted entity transmits a readiness signal to the WTRU. The WTRU transmits data classified for transfer to the trusted entity, and the trusted entity stores the data classified for transfer in a memory of the trusted entity.
