摘要:
A method for graphically indicating the positions of nodes connected to an ad hoc network is described. The method permits graphic display of the positions of the configured nodes including at least a node having a position-information detection device such as a GPS receiving device and a node having no such device for detecting its own position information, the graphic display being accomplished based on position information obtained by the detection device and on routing information about the node with no position-information detection device.

One objective of the present invention is to determine a location for a relay terminal in a radio network, without preparatory surveying a radio status, and to arrange the relay terminal at the location. Another objective is to provide a method for retrieving the arranged relay terminal. When a relay terminal is to be arranged, the relay terminal transmits a survey packet to examine the quality of communication with a communication terminal or other relay terminal. Wherer a location is appropriate, the relay terminal gives a notice. The arranged terminal relays communication. Further, when the relay terminal is to be retrieved, the relay terminal carried by a user transmits a retrieval packet to the arranged relay terminal, which notifies the user of its presence by light, sounds, or returning a packet. In this manner, a single relay terminal provides functions of arrangement, relay and retrieval.

摘要:
An aspect of the invention is an information terminal device includes a widget management unit for managing execution of a widget being a monofunctional program for performing display on the display part of a display device. The widget management unit includes a policy determination unit for determining the operation policy, including operation restriction and priority, concerning a display state at the display device in the widget, and a reliability determining unit for determining the reliability representing the reliability of the widget in the widget. When the state of the movement calculated by a navigation unit becomes a preset state, the widget management unit regulates the display state of the widget according to the operation restriction and the reliability, and performs display, while preferentially displaying guidance state and positional information calculated by the navigation unit.
摘要:
A mobile terminal retains a communication device allocation priority table in which the allocation priorities of communication devices to respective applications are recorded for each of the communication devices mounted to the mobile terminal. The allocation priorities are determined from the combination of the types of an application and the operation state of the application. The mobile terminal allocates the communication devices to the applications in accordance with the priority orders recorded in the allocation priority table. The allocation priorities recorded in the communication device allocation priority table are varied in accordance with the operation states of the applications and the presence/absence of an alternate device.
摘要:
In a client processing apparatus, each application program independently performs communication with a server processing apparatus in spite of relevance between the application programs. For example, when plural application programs issue a request at the same timing in correspondence with a user's operation, the operation speed of the application program may become low. A request which occurs at the same timing of a particular request outputted from an application program to the server processing apparatus is previously defined in a communication grouping table. When the application program actually outputs a request, the communication grouping table is referred to, then the request and a request in the table to occur at the same timing are transmitted at once to the server processing apparatus. The server processing apparatus processes the plural requests at once, and returns the result of processing to the client processing apparatus.

An object of the present invention is to provide communication equipment, an inter-vehicle communication control method, and an inter-vehicle communication system by which information can be efficiently transmitted to a designated range even at a blind intersection or on a curved road. Communication equipment that received transfer data including data to be transferred, position information of a destination of the data to be transferred, position information of relay points used to determine a route to the destination, and position information of the last transferring vehicle determines a standby time that becomes shorter as a distance between the position of the last transferring vehicle and the position of the host vehicle becomes longer in the case where the host vehicle is not located in a predetermined range on the basis of the relay points. In addition, the communication equipment determines the standby time that becomes longer as a distance between the position of the host vehicle and the position of the relay point becomes longer in the case where the host vehicle is located in the predetermined range, and performs a process of transmitting the transfer data after the standby time passes.
