Abstract: A multimedia messaging center is arranged to receive multimedia messages addressed to a terminal. In response to the receipt of such messages, the message center transmits a notification to the terminal regarding the received message. A wireless message is transmitted, from the terminal to the message center, requesting notification messages that have not been acknowledged as received by the terminal.

Abstract: A method provides control of access to shared content in a communication system. The method comprises obtaining presence information with at least one access criterion associated with an access to shared content. The method further comprises receiving an access request requesting an access to at least one part of the shared content.

The method further comprises processing the access request based on a result of the step of verifying. Furthermore, a controlling entity is configured to execute the method.

Abstract: The invention relates to a method of transferring a multimedia message in a multimedia messaging system, which comprises a terminal (MS) and a multimedia messaging centre (MMSC), which are arranged to communicate with each other at least partially wirelessly. The multimedia messaging centre (MMSC) is arranged to receive multimedia messages addressed to the terminal (MS) and transmit a notification message to the terminal (MS) to inform it of a multimedia message addressed to the terminal (MS) which has arrived at the multimedia messaging centre (MMSC). The method comprises transmitting a first message (11) wirelessly from the terminal (MS) to the multimedia messaging centre (MMSC), the first message (11) requesting the multimedia messaging centre (MMSC) to transmit a notification message (12) to the terminal (MS) on the multimedia messages addressed to the terminal (MS) which have arrived at the multimedia messaging centre and on which the terminal (MS) has not received a notification message yet.

Abstract: The invention relates to a method for transmitting information between applications (A1, A2) executed in a first (TE1) and a second data transmission device (TE2) in a data transmission system. In the transmission of information, a data transmission protocol is used, wherein in the method one or more protocol conversions are conducted in the protocol stack (ST) for the information to be transmitted, said protocol stack comprising at least an application layer (L7) and a physical layer (L1). At the transmission stage messages (FR1) are produced from the information in the application layer (L7).
