Abstract: A communication method of a mobile terminal for reliably performing call redirection between heterogeneous or homogeneous mobile communication systems is provided. The communication method includes requesting a first base station of a first mobile communication system to establish a call connection, receiving information about a first frequency of an adjacent base station for call redirection from the first base station in response to the call connection request, searching for one or more frequencies for the call redirection using the information about the first frequency and information about a second frequency of at least one second mobile communication system, selecting a frequency for the call redirection from among the searched frequencies, and sending a call connection request to a second base station using the selected frequency.

Abstract: An image forming apparatus and method of printing an image in the image forming apparatus connected to an image storage device, the method including: selecting at least one image stored in the image storage device; setting up print options with regard to the selected at least one image; starting a transmission of image data corresponding to the selected at least one image from the image storage device to the image forming apparatus before the setting up of the print options is completed; and printing the image data according to the setup print options.

Abstract: An apparatus and method for ascertaining a movement pattern of a user who moves on a fixed path, predicting a destination cell on the movement of the user, and preventing a cell reselection process to an unnecessary intermediate cell. The apparatus includes a pattern management unit configured to analyze movement of a user and ascertain a movement pattern of the user. The apparatus also includes a memory configured to store the movement pattern of the user, which is ascertained by the pattern management unit. The apparatus also includes a controller configured to ascertain information about a destination cell and information about an intermediate cell through which the user passes before moving to the destination cell using the movement pattern of the user and a current movement path of the portable terminal. The apparatus also includes a cell reselection unit for performing a cell reselection process to the destination cell.

Abstract: A method and device to transmit and/or receive fax data in a fax machine or a multifunctional device including a fax function. The method of transmitting the fax data may include transmitting fax data intended to be transmitted to an external device using a user datagram protocol (UDP), receiving a signal requesting that the fax data be re-transmitted from the external device when an error occurs in the transmission of the fax data, and re-transmitting the fax data to the external device in response to the request signal. Accordingly, the fax on a receiving end checks whether a transmission error occurred when data is transmitted from a fax of a transmitting end using a UDP, and, when a transmission error is present, transmits a request signal requesting that the data be re-transmitted to the fax on the transmitting end. At this point, the data is immediately re-transmitted. Therefore, reliability of fax data transmission is increased and the time required for data transmission can be reduced.

Abstract: A facsimile transmission speed setting method, medium, and apparatus. The facsimile transmission speed setting method may include transmitting a DCS signal and a Training Sequence using a transmitting fax unit that receives the DCS signal from a receiving fax unit, checking the Training Sequence at a receiving side of the receiving fax unit, and if there is no transmission error in the received Training Sequence, maintaining a current transmission speed by transmitting a CFR signal to the transmitting fax unit, checking for a transmission error in Training Sequence, and checking whether the transmission error is within a predetermined range. If the transmission error is within the predetermined range the current transmission speed is maintained by transmitting the CFR signal to the transmitting fax unit, and if the transmission error is not within the predetermined range the transmission speed is reduced by transmitting an FTT signal to the transmitting fax unit.
