ABSTRACT:
In a communication apparatus comprising a receiving section (102, 103, 104) for receiving message data transmitted from a base station as received message data, and a detection section (105) for detecting a transmission number in the received message data to produce a current transmission number, a determining section (106, 107, 108, 109) compares the current transmission number with a previous transmission number to determine whether or not a difference between the current transmission number and the previous transmission number is not less than two and is not more than a predetermined number which is not less than three. When the difference is not less than two and is not more than the predetermined number, an alert section (110) alerts transmission number omission. The predetermined number may be equal to nine when the transmission number is represented by 0 to 31 in decimal. When the current transmission number is equal to the previous transmission number, current received message data is ignored preferably.
