  • Patent number: 8326350
    Abstract: A communication terminal optimally switches between the use of multicast reception and unicast reception, in consideration of the mobile radio environment of each terminal. For example, received signal strength indicator information is acquired at a received signal strength indicator information acquisition time calculated using a content reception time. Either multicast reception or unicast reception is selected according to the acquired received signal strength indicator information and content reception is performed. An optimal reception system can be selected and reception failure can be reduced. In addition, by performing a dynamic switching of reception methods as such, the base station-end can perform multicast delivery rather than unicast delivery when possible to communication terminals in favorable mobile radio environments, thereby significantly reducing the traffic load placed on communication paths.

  • Patent number: 8036363
    Abstract: A communication processing unit includes communication processing units which use different communication manners. A user interface unit receives input of information indicating a calling destination from a user. An information storage unit stores a person to contact and plural phone numbers of that person in association. When a person to contact is input to the user interface unit, a control unit acquires a phone number associated with the input person, and information indicating a communication manner to be used from the information storage unit, and controls the communication processing unit to make a call to the acquired phone number in the acquired communication manner. If the person to contact has plural phone numbers, the control unit controls the communication processing unit to make calls to these phone numbers in parallel.

  • Publication number: 20110193774
    Abstract: In an operation control device for controlling the operation of an appliance such as television receiver, a human-perceiving sensor is used as a unit for detecting movements of the operator. Then, continuous movements are extracted therefrom, such as hand-waving movements performed by the operator with an intention of operating the appliance such as television receiver. Moreover, if the operator performs one and the same movement during a time-period which is longer than a certain constant time-period, a control determined in advance is exerted over the operation control device. Also, the situation in which the movements of the operator are detected is displayed on the appliance such as television receiver, so that the operator is permitted to perform a more accurate movement by the resultant feedback effect.

  • Publication number: 20110021161
    Abstract: In a wireless communication terminal, information from a wireless communication unit is decoded by a communication control unit and analysis information is acquired. A content reception judgment unit instructs the communication control unit to terminate a content receiving process if a mobile radio environment corresponding to transmission rate information of the contents, included in the analysis information, is below a content reception threshold stored in a content reception threshold storage unit. Thus, the wireless communication terminal can judge that the possibility of a failed reception is high before content reception, and needless power consumption can be prevented and power consumption reduced by not performing reception.

  • Patent number: 7865195
    Abstract: Location positioning setting information is read from a setting storage section when the user depressed a power key. The location positioning setting information comprises setting information, such as the maximum duration time of the location positioning operation and the operation timing when a power-off event has been generated. A control section turns off the power of a display section, a speaker, a microphone, etc., excluding a communication function for transmitting location positioning and positioning results. In this state, a location positioning section acquires the positional information of the mobile communication terminal. Then, a wireless communication section transmits the location positioning information of the positioned mobile communication terminal to a predetermined monitoring server which manages the positional information of the mobile communication terminal.

  • Patent number: 7463888
    Abstract: A wireless processing section has modulation/demodulation circuits which contain communication protocols used for a plurality of communication systems. A communication control section performs an entering idle state process according to a selected communication mode by a communication processing selection section and executes an entering idle state process by switching communication modes until an entering idle state process is successful. Subsequently, when an entering idle state process is successful, a maximum number of origination retry attempts is determined corresponding to a required time interval until completion of that entering idle state process. Specifically, the maximum number of origination retry attempts is decreased to the extent that the time interval until an entering idle state process completion becomes longer. The communication control section performs retries fore only the determined maximum number of origination retry count attempts when connection failed in an origination process.
