Title: Selective calling system and selective calling receiver

Abstract: A transmission signal frame format includes an address field and a message field. The address field includes a plurality of addresses associated with the subscriber's receivers to be called, respectively. The message field includes a plurality of messages corresponding to the addresses, respectively. A message includes a transmitting sequence number which is coincident with the transmitting order of the address corresponding to this message. A selective calling receiver, receiving a frame, sequentially searches the address field for the ID address of its own while incrementing a receiving sequence count at each the address. When the ID address is found, the receiver stores the receiving sequence count at that time. The receiver selects its own message data from the message field when the transmitting sequence number of a message is coincident with the receiving sequence count.
