Abstract: A communication apparatus such as a cellular phone is described in which a control unit judges, when an incoming call is received, whether a sounding unit or a vibrating unit is to be activated for announcing the reception of the incoming call. The control unit determines that the announcing of the reception is prohibited if the mobile communication apparatus is in a roaming area. When the announcing of the reception is prohibited, the control unit sends a message, showing that the reception of the incoming call is unavailable, to a calling party.

Abstract: A location registration control unit stores PSC used in a roaming prohibition cell in a prohibition cell list storage area. After that, if the reselection of cells is required for the reason that the receiving conditions become worse or other reasons, a reselection control unit detects PSC of neighbor cells, creates a list of the detected PSC regarded as candidates, stores the list in a candidate cell list storage area, receives notification information from the cell using the PSC other than the roaming prohibition cell in the list, and executes reselection.

Abstract: A communication apparatus includes: an e-mail creating unit configured to create the e-mail with specifying an e-mail address of a destination; an e-mail transmitting/receiving unit configured to transmit/receive the e-mail; a display unit provided with a received mail display area for displaying a received e-mail set if necessary and a created mail display area for displaying an e-mail being created; and a control unit configured to set the received mail display area and display the received e-mail if the e-mail is received during creating the e-mail and the e-mail address of a sender of the received e-mail matches with the e-mail address of the destination of the e-mail being created.

Abstract: A 3G wireless control unit, a WiFi wireless control unit, and a WiMAX wireless control unit each select one data communication method from data communication methods that each supports, and any one supporting the selected data communication method performs communication using the selected data communication method. A 3G non-coverage area search processing unit, a WiFi non-coverage area search processing unit, and a WiMAX non-coverage area search processing unit each detect a base station supporting a data communication method that each supports. A search control unit controls the frequency of execution of a base-station detecting process performed by the WiMAX non-coverage area search processing unit on the basis of respective communication states and predetermined priorities of data communication methods.

Abstract: A mobile communication terminal has a function of communicating with two types of base stations, for example, one base station belongs to the Global System for Mobile communications (GSM) and another base station belongs to the Wideband Code Division Multiple Access (WCDMA) system. The mobile communication terminal receives radio signal from a communicating base station and a neighboring base station, and measures received radio signal quality. Then, judging whether hand-over process is to be executed or not based upon comparison of the measured received radio signal quality and relationship between the received radio signal quality and data throughput.

Abstract: Control unit controls sender-receiver unit to execute cell search. As a result, if control unit attempts location registration via base station and the use is rejected, control unit stores identification information of the network to which the base station belongs in inhibit network list storage area, stores identification information of a carrier frequency used for communications with the base station in inhibit frequency list storage area, and detects a cell capable of carrying out communications on the basis of the identification information stored in the storage areas.
