The embodiments disclosed herein relate to a location-based service providing information depending on a position through a network.
A location-based service is known which provides position-dependent information depending on a position, to a communication apparatus. The provided position-dependent information is, for example, peripheral map information, route information which guides a moving route, and service information of periphery facilities. For example, an electronic device measures a current position by using positioning methods such as GPS (Global Positioning System) and an AFLT (Advanced Forward Link Trilateration). A communication apparatus transmits the measured current position to a server apparatus on a network, and downloads the position-dependent information from the server.
Moreover, a technique is known wherein the technique includes generating schedule data indicating contents of the schedule when a user registers a schedule of travelling abroad into a mobile phone, transmitting the schedule data from the mobile phone at the time of a location update, when a user holding the mobile phone moves to a communication area corresponding to a network to which the user does not subscribe, and distributing various kinds of information items to the mobile phone based on the schedule data by an information providing server.
Further, another technique is known, which includes inquiring, to a communication area information managing unit, whether or not the associated position is inside a communication area, with respect to the contents predicted to be referred to according to a movement based on a current position, a moving direction and a moving speed of a terminal, selecting one or more communication units with line quality sufficient to communicate when the terminal is outside the communication area, acquiring, in advance, the contents predicted to be referred to using the selected communication unit, and accumulating the acquired contents. The terminal device includes an acquisition content determining unit and a content acquisition unit. When a position corresponding to a position related content predicted to be referred to is outside the communication-capable area, the acquisition content determining unit selects the position related content as the position related content to be acquired at a current position. The content acquisition unit acquires the position related content selected by the acquisition content determining unit from a content server by wireless communications, and accumulates the acquired content in an accumulating unit. The acquisition content determining unit determines a moving route and a destination based on a user's action schedule or the like, and selects the moving route and the position related contents around the destination as reference candidate contents.

The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, as claimed.
Depending on a user's current position, there is a case in which it is difficult for a user to receive a location-based service, and a case in which a user does not desire to receive the service. An example of a former case is when a communication service for receiving a location-based service due to a user's location is difficult to ascertain. For example, there may be many areas in foreign countries in which packet communication is not possible.
An example of the latter case is high cost for using a location-based service, depending on a user's location. According to development of international roaming in recent years, in many cases, a communication apparatus which subscribes a service of the carrier in one country can receive a location-based service in other countries. However, when a location-based service is used in other countries with the international roaming, the communication fee is high in many cases. Therefore, there are only a few users who use the location-based service in other countries at present.
In order to solve the above-mentioned matter, a measure can be assumed to be taken in which a user downloads position-dependent information in advance, before moving to a place at which a location-based service is difficult to be received, or a place at which it is not desired to receive the location-based service. However, according to such measure, when the information downloaded in advance is not actually used in the country, the information which is not used will also be charged and this leads to wasteful cost.
An object of a apparatus and a method disclosed herein is to enable billing in accordance with the information quantity actually used in the area concerned, when downloading position-dependent information to be used in the area concerned in advance before moving into the area concerned, in order to use a location-based service in the area.
According to an apparatus and a method disclosed herein, it enables billing in accordance with the information quantity actually used in the area concerned, when downloading position-dependent information to be used in the area concerned in advance before moving into the area concerned, in order to use a location-based service in the area.

At the time when the information acquisition unit 61 downloads, from the route retrieval server 4 and the map server 5, the used flag of all used information quantity data is “OFF”.
Referring to
The output information control unit 62 determines whether or not the electronic device 2 is located in the second geographical area based on the position information of the electronic device 2 measured by the positioning unit 43. The output information control unit 62 is permitted to start the location-based service which presents, to a user, the route information and the map information stored in the route information storing unit 52 and the map information storing unit 53, when determining that the electronic device 2 is located in the second geographical area.
In some embodiments, when the output information control unit 62 determines that the electronic device 2 is located in the second geographical area, the output information control unit 62 may output, from the output unit 35 to the user, a message which prompts a user to use the location-based service which presents the route information. When a user performs an operation to select a use of the location-based service at the input unit 41, the output information control unit 62 may start providing the location-based service.
The output information control unit 62 retrieves, from the route information storing unit 52, the route information to reach the implementation place of each schedule registered in the schedule information, and outputs the retrieved route information through the output unit 35. When the route information depicted in
The output information control unit 62 compares the position information of the electronic device 2 measured by the positioning unit 43 with the coordinate information of the implementation place of each schedule stored in the coordinate information storing unit 56. When the distance between the measured position information of the electronic device 2 and the coordinate information of the implementation place of each schedule falls within a predetermined range, the output information control unit 62 may determine that the device has arrived at the implementation place. When a user has arrived at the implementation place of each schedule, the output information control unit 62 retrieves, from the route information storing unit 52, the route information to reach the implementation place of a subsequent schedule registered in the schedule information, and outputs the retrieved route information through the output unit 35.
For example, after outputting the route information depicted in
The output information control unit 62 determines whether or not the electronic device 2 is located within the range of the map information stored in the map information storing unit 53. When the electronic device 2 is located within the range of the stored map information, the output information control unit 62 may output, from the output unit 35 to a user, a message which prompts a user to use the location-based service which presents the map information. When a user performs an operation to select the use of the location-based service at the input unit 41, the output information control unit 62 may start providing the location-based service.
After that, the output information control unit 62 outputs the map information from the output unit 35, when the electronic device 2 is located within the range of the map information stored in the map information storing unit 53. The output information control unit 62 continuously acquires the position information of the current position of the electronic device 2, and retrieves the map information according to the acquired current position from the map information storing unit 53. The output information control unit 62 then outputs the retrieved map information through the output unit 35.
The output information control unit 62 may receive an input operation to change the scale of the map, the input operation being performed by a user through the input unit 41. When the input operation to change the scale is received, the output information control unit 62 may retrieve the map information of the changed scale from the map information storing unit 53, and may output the retrieved map information to the output unit 35. At this time, the output information control unit 62 may adjust the output range so that the current position of the electronic device 2 may be located at the center of the output range.
Whenever the user arrives at the implementation place of each schedule, the output information control unit 62 determines whether or not the subsequent schedule is a schedule in the first geographical area. For example, the output information control unit 62 may determine whether or not the subsequent schedule is the schedule in the first geographical area by referring to the information element “area flag” of the subsequent schedule. In other embodiments, the output information control unit 62 may determine whether or not the subsequent schedule is the schedule in the first geographical area by referring to the information element “place” of the subsequent schedule.
When the subsequent schedule is a schedule in the first geographical area, i.e., a first schedule after the second movement, the output information control unit 62 retrieves, from the route information storing unit 52, the route information from the last schedule before the second movement to the departure point of the second movement, and outputs the retrieved route information through the output unit 35.
For example, when a user arrives at the implementation place of the schedule with the schedule item number “5” depicted in
When retrieving the information from the route information storing unit 52 and the map information storing unit 53, the output information control unit 62 updates the used information quantity data stored in the used information quantity storing unit 55. The output information control unit 62 sets the value of the used flag stored corresponding to the identifier of the retrieved information to “ON”, and stores a fact that the retrieved information is the used information.
The used information quantity transmitting unit 63 determines whether or not the second movement for moving to the first geographical area from the second geographical area has been performed. For example, the used information quantity transmitting unit 63 may determine whether or not the electronic device 2 is located in the first geographical area based on the position of the electronic device 2 measured by the positioning unit 43. When the electronic device 2 is located in the first geographical area, the used information quantity transmitting unit 63 may output a message for inquiring a user whether the second movement has been performed through the output unit 35. When a user operates the input unit 41 for answering that the second movement has been performed, the used information quantity transmitting unit 63 may determine that the second movement has been performed.
When it is determined that the second movement has been performed, the used information quantity transmitting unit 63 determines the information quantity of the used information by referring to the used information quantity data stored in the used information quantity storing unit 55. When the information element “data quantity” of the used information quantity data is stored in the external storage device, the used information quantity transmitting unit 63 accesses the external storage device to acquire the information quantity data of the used information.
The used information quantity transmitting unit 63 transmits the information quantity data indicating the information quantity of the used information to the billing server 6 through the communication unit 42, as the information quantity data of the information acquired by the electronic device 2 from the information distribution system 1. The billing server 6 determines the charging amount for the information used by the electronic device 2 in the second geographical area according to the information quantity data transmitted from the used information quantity transmitting unit 63.

Referring to
Next, processing in the electronic device 2 for a user to use the route information and the map information by in the second geographical area will be illustrated.
Next, the billing processing performed in the first geographical area after the second movement will be illustrated.
In operation EA, the positioning unit 43 measures the position of the electronic device 2. In operation EB, the used information quantity transmitting unit 63 receives the position information of the electronic device 2. In operation EC, the used information quantity transmitting unit 63 determines whether or not the second movement for moving to the first geographical area from the second geographical area has been performed.
When it is determined that the second movement has been performed, in operation ED, the used information quantity transmitting unit 63 determines the information quantity of the used information by referring to the used information quantity data stored in the used information quantity storing unit 55. In operation EE, the used information quantity transmitting unit 63 transmits the information quantity data indicating the information quantity of the used information to the billing server 6. In operation EF, the billing server 6 performs the billing processing according to the information quantity data transmitted from the used information quantity transmitting unit 63.
According to the present embodiment, the electronic device 2 can use the location-based service in the second geographical area by using the position-dependent information of the second geographical area which is accumulated when the electronic device 2 is located in the first geographical area. Moreover, the billing processing is also performed when it is located in the first geographical area. Therefore, when using the location-based service in the second geographical area, the electronic device 2 can omit the use of the communication service in the second geographical area. Therefore, a user can receive the location-based service even when the user is difficult to receive the location-based service through the communication service in the second geographical area, or even when the user does not desire to receive such location-based service.
According to the present embodiment, it is possible to determine the charging amount in conformity with the actual usage, because of storing which information has been actually used in the second geographical area among the position-dependent information of the second geographical area accumulated in the first geographical area. Therefore, it is possible to prevent excessive billing for information which a user has not used.
Even if the information which a user is likely to use is predicted with an extra amount to be accumulated in the electronic device 2, it is possible to prevent the occurrence of charging a fee to the information which the user does not actually use. Therefore, more information can be stored in the electronic device 2 so as to provide the location-based service with high convenience.
Next, another embodiment of the electronic device 2 is illustrated.
The position determination unit 64 receives a positioning result of the electronic device 2 performed by the positioning unit 43. The position determination unit 64 retrieves, from the coordinate information storing unit 56, the coordinate information of any place in the second geographical area stored in the coordinate information storing unit 56. The position determination unit 64 compares the coordinate information retrieved from the coordinate information storing unit 56 and the positioning result of the electronic device 2, to determine whether the electronic device 2 is located in the second geographical area. When the position determination unit 64 determines that the electronic device 2 is located in the second geographical area, the output information control unit 62 starts the location-based service which present to a user the route information and the map information stored in the route information storing unit 52 and the map information storing unit 53, respectively.
The coordinate information which is retrieved from the coordinate information storing unit 56 to be compared with the positioning result by the position determination unit 64 may be the coordinate information stored in the coordinate information storing unit 56 with respect to the implementation place of each schedule registered in the schedule information. The coordinate information which is retrieved from the coordinate information storing unit 56 to be compared with the positioning result by the position determination unit 64 may be the place information stored in the coordinate information storing unit 56 with respect to the information element “arrival airport” of the first schedule after the first movement. In other words, the coordinate information may be the coordinate information of the arrival point of the first movement. The arrival point of the first movement may be, for example, a departure-and-arrival place of the transportation in the second geographical area used for the first movement.
The activation detecting unit 45 detects that the electric power source of the electronic device 2 is switched from OFF to ON. The position determination unit 64 may determine whether or not the electronic device 2 is located in the second geographical area, only when the electric power source of the electronic device 2 is switched to ON by the activation detecting unit 45. When the movement to the second geographical area from the first geographical area is by an air flight, the electric power source of the electronic device 2 is made into an OFF state during the movement, and when arriving at the second geographical area, the electric power source of the electronic device 2 is switched ON.
Therefore, by determining the position of the electronic device 2 at the timing of switching on the electric power source of the electronic device 2, it is possible to guess that the electronic device 2 is located in the arrival airport for the air flight used for the movement to the second geographical area.
In operation FA, the activation detecting unit 45 determines whether or not the electric power source of the electronic device 2 is switched from OFF to ON. When the electric power source of the electronic device 2 has been switched from OFF to ON (operation FA: Y), processing proceeds to operation FB. When the electric power source of the electronic device 2 has not been switched from OFF to ON (operation FA: N), processing returns to operation FA.
In operation FB, the positioning unit 43 measures the position of the electronic device 2. In operation FC, the position determination unit 64 determines whether or not the electronic device 2 is located in the second geographical area. When the electronic device 2 is located in the second geographical area (operation FC: Y), processing proceeds to operation FD, and the location-based service is started. When the electronic device 2 is not located in the second geographical area (operation FC: N), processing is terminated. The following operations FD to FP are substantially the same as the operation BC to BO illustrated with reference to
According to the present embodiment, the location-based service which provides the information stored in the route information storing unit 52 and the map information storing unit 53 is started only when the electronic device 2 is located in the second geographical area. Therefore, the fault in the billing processing due to the service being incorrectly started in an area which is different from the second geographical area is prevented.
According to the present embodiment, it is possible to start a location-based service from the time when it is detected that the electronic device 2 is located at the arrival airport of the air flight for the movement to the second geographical area as planned. Therefore, since a location-based service does not start in a state where a user takes different action from a schedule, it is possible to prevent the occurrence of charging a fee due to a display of unnecessary information.
