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.

Abstract: Messaging service interoperability methods. A client implements a messaging service version (X.Y), in which X is a major version number and Y is a minor version number. The client sends a PDU (Protocol Data Unit) with version (X.Y) to a server. If the PDU with version (X.Y) is not accepted by the server, the client reselects a messaging service version (Z.H), and sends a PDU with the reselected version (Z.H) to the server. Reselection of the messaging service version and sending of a PDU with the reselected version are repeated until the PDU is accepted by the server or all possible reselected versions have been selected.

Abstract: A method for log management utilized in a mobile station is provided. The method includes the following steps. An accumulated history log comprising multiple accumulated history records is generated. A menu comprising multiple menu items corresponding to the accumulated history records is displayed. The accumulated history log contains no records representing redundant phone numbers.

Abstract: A method and a mobile unit for transmitting and for receiving contact information are provided. A memory for transmission stores a profile datum and a multimedia datum of the contact information. An encoder retrieves the profile datum and the multimedia datum from the memory, encodes the profile datum in a first format into a first file, and encodes the multimedia datum in a second format into a second file. A transmission unit transmits both of the first file and the second file. A receiving unit receives a first file and a second file. A processor determines whether the first file and the second file comprise the profile datum and the multimedia datum, and generates a signal if yes. A decoder decodes the profile datum in the first format and decodes the multimedia datum in the second format in response to the signal. A memory for receiving stores the decoded profile datum in a first location based on the first format and the decoded multimedia datum in a second location based on the second format.
