Abstract: A remote control apparatus and method are provided for controlling an image forming device using wireless data communication by establishing a wireless connection with the image forming device. A wireless interface receives image data stored in a storage medium of an image forming device and transmits a signal requesting an activity for an image corresponding to the received image data, using wireless data communication. A display unit displays an image using the received image data, and a user input unit receives an activity to be performed. By displaying images stored in the image forming device, or an external storage medium, using the wireless remote control apparatus and allowing a user to select an image among the displayed images and request the image forming device to perform an activity, such as a printing or editing activity, a specific activity can be requested from the image forming device without spatial limitation.

Abstract: An apparatus and method for providing a multicast/broadcast service in a mobile communication system. Upon detecting an occurrence of a multicast data packet, an Internet Protocol (IP) terminal converts the multicast data packet into an alternative multicast data packet, and transmits the alternative multicast data packet to a femto Node B. Upon detecting an occurrence of a broadcast data packet, the IP terminal converts the broadcast data packet into an alternative broadcast data packet, and transmits the alternative broadcast data packet to the femto Node B.
