摘要:
A navigation device performs a route guidance based on a route from a current location to a destination, the navigation device being connected to a server for searching the route. A navigation method for the navigation device includes sending a request for searching the route to the server and receiving information on the route from the server. The method also includes measuring an elapsed time from a start of the route guidance, and performing the route guidance based on the information received. The method further includes cutting off a communication with the server and coming into a standby state, upon a determination that the elapsed time measured has reached a predetermined time and when the route is being guided or a current location is being checked, to decrease a bandwidth usage between the navigation device and the server and to reduce a communication charge associated with the bandwidth usage.

Guide points can be grasped by use of a mobile terminal. The mobile terminal comprises search condition transmitting means (KC16A) for transmitting data of route searching conditions to a server; searching result receiving means (KC1A) for receiving, from the server, route data produced by the server in accordance with the route searching conditions; map request information transmitting means (KC16B) for transmitting, to the server, map data transmission request information for requesting a transmission of map data; map data receiving means (KC1B) for receiving the map data transmitted from the server; route image producing means (KC7) for producing a route image based on a range in which to display on the information display screen (11) and based on the route data; and guide map image producing means (KC8) for producing a route guidance map image by combining, based on the map data, a map image and the route image.

An image data transmitting/receiving system for displaying an image having an optimum size in accordance with the resolution of an information display screen (11) of a mobile terminal (1), comprising the mobile terminal (1) and a server (7). The mobile terminal (1) comprises terminal-side symbol image data storing means (KC2) for storing data of symbol image used for producing a displayed image; and symbol image data transmission request information transmitting means (KC10B) for transmitting information related to the resolution of the information display screen (11) to the server (7). The server (7) comprises server-side symbol image data storing means (SC2A) for storing a plurality of symbol image data in accordance with the resolution of the information display screen (11); terminal resolution determining means (SC3) for determining, based on the received resolution related information, the symbol image data to be transmitted to the mobile terminal (1); and symbol image data transmitting means (SC5B) for transmitting the symbol image data in accordance with the aforementioned resolution.

摘要:
A navigation device, which performs a route guidance based on a route searched by a server, includes: a communication controller that sends a request for searching the route to the server; a guidance-information receiving unit that receives information on the route from the server; and a guidance controller that performs the route guidance based on the information received. The communication controller determines whether to send the request based on a status of the navigation device, such as a status of a travel of the navigation device (travel time, travel distance, etc.), thereby decreasing traffic between the navigation server and reducing communication charges.
摘要:
A navigation device having a function of dealing with a case where a navigation function cannot be executed at the same time as another function, such as a telephone function, because of constraints of the processing capability of a CPU or the memory capacity in a mobile telephone. A navigation device (10), which uses a mobile telephone having GPS means, comprises a navigation control module (123); a telephone communication control module (122) for telephone communicating with another mobile terminal device; and an operation control module (OS) (121) for controlling those modules. When detecting a particular event during operation of the navigation control module, the OS sends a suspension command to the navigation control module, thereby suspending the navigation control module. When detecting a termination of the particular event, the OS sends a resumption command to the navigation control module, thereby resuming the navigation control module.

摘要:
A display unit displays a route search result. A memory unit stores route search criteria including a destination. A route-search-result obtaining unit obtains, when a route search instruction including a designated location is received while the route search result is displayed on the display unit, the route search result with the designated location as a departure point and the destination included in the route search criteria stored in the memory unit as an arrival point.

A navigation device performs a route guidance based on a route from a current location to a destination. A communication controller sends a request for searching the route to a server. A guidance-information receiving unit receives information on the route from the server. A time measuring unit measures an elapsed time from a start of the route guidance. A guidance controller performs the route guidance based on the information received. The communication controller commands the navigation device to cut off a communication with the server and to stand by upon a determination that the elapsed time measured has reached a predetermined time and when the route is being guided or a current location is being checked by the guidance controller, to decrease a bandwidth usage between the navigation device and the server and to reduce a communication charge associated with the bandwidth usage.
