Abstract: A receiver terminal, like a mobile apparatus or a mobile phone, downloads a multimedia message from a message center via a network. An arrival notification is first transmitted from the message center to the receiver terminal. In the notification, a length of the multimedia message is identified. The receiver terminal, however, checks a portion of the multimedia message downloaded to ensure the actual size indicated by the portion of the multimedia message is consistent with the length identified by the notification. If there is problem, users are inquired for confirmation to determine whether to continue downloading the rest portion of the multimedia message.
