ABSTRACT:
A paging receiver of the present invention includes a decoder for processing a paging number and a message signal of a transmitted radio signal and receives the radio signal selectively by comparing the paging number with a predetermined paging number of the receiver. A timer stamps the message signal with current time when the paging number coincides with the predetermined paging number of the receiver. A memory stores message signals already received and stamped with time information. The message signal stamped with current time is compared with the message signals stamped with received time stored in the memory and, when contents of these message signals are coincident and a difference in time between these message signals is within a predetermined time, the message signal is deemed as an urgent message and an urgent report is performed.
