Abstract: The use of a data link between two or more smart devices for voice communication allows for the enhancement of voice quality in a collaborative way through the exchange of well-defined meta-data between the smart devices. The meta-data may be exchanged on a separate IP data link or as part of the exchanged voice data packets.

Abstract: According to an aspect of the invention a teleconferencing system is conceived, which teleconferencing system comprises a master communication device and a plurality of satellite communication devices, wherein the master communication device is arranged to communicate with a far-end communication device through a global communication channel and to communicate with the plurality of satellite communication devices through a plurality of local communication channels, wherein the master communication device is further arranged to act as a portal between the far-end communication device and the satellite communication devices by forwarding voice communications received from the far-end communication device to the satellite communication devices through the local communication channels, and by mixing voice communications received from the satellite communication devices into a unified voice signal and sending said unified voice signal to the far-end communication device through the global communication channel.

Abstract: System and method for adjusting a sound notification volume a mobile device are disclosed. Accordingly, the transmission signal strength is measured at the mobile device for a transmission link between the mobile device and a smart companion device that is paired with the mobile device. Subsequently, using a calibration data and the measured signal strength, a distance between the mobile device and the smart companion device is estimated. Then, using a configuration that is preset in the mobile device and the estimated distance, the sound notification volume of the mobile device is adjusted.

Abstract: A system for and method of controlling retransmission of a content item contained in a multimedia message, comprising receiving the message containing the content item from a sender together with an identifier of an intended recipient of the message, obtaining an identifier for the content item, retrieving approval information from a provider based on the identifier for the content item, and controlling retransmission of the message including the content item to the intended recipient based on the retrieved approval information. Controlling may comprise e.g. charging a fee for the retransmission, restricting forwarding of the content item or disallowing the retransmission. If the additional information identifies plural providers, retransmission can be made conditional upon approval by any of the plural providers.

Abstract: A system for and method of controlling retransmission of a content item contained in a multimedia message. The method comprises: receiving the message containing the content item from a sender together with an identifier of an intended recipient of the message, processing the content item to detect the presence or absence of a watermark therein, if the absence of a watermark has been detected, *causing a watermark to be embedded in the content item, and* allowing retransmission of the message including the watermarked content item to the intended recipient, and otherwise controlling retransmission of the message including the content item to the intended recipient. Controlling may comprise e.g. charging a fee for the retransmission, restricting forwarding of the watermarked content item or disallowing the retransmission. The invention relates to the Multimedia Messaging Service (MMS).
