ABSTRACT:
From a paging station a radio display pager receives a sequence of repeat calls and non-repeat calls. Each of the repeat and non-repeat calls contains a message and a message number identifying the message, the same message numbers being repeated for the repeat calls of the sequence. The message numbers of received calls are stored in a first memory. A currently received call is compared with each of the previously stored calls to detect a mismatch. Upon detection of the mismatch, a lost call detector determines the message number of a lost call which may exist between the currently received call and a call stored last in the first memory. The determined message number is stored into a second memory as a lost message number. The stored lost message number is erased if a call bearing the same message number is received. The lost message number that remains in the second memory is put on display to allow the owner of the pager to inform the system center of the lost message number to obtain the lost message.
