Abstract

A mobile phone A and a mobile phone B are in a call process and are capable of performing voice communication with each other. In such a state, the mobile phone A activates a GPS and acquires location information when an instruction to determine the location information about a location of the mobile phone A is received from an owner of the mobile phone A during a call process to the mobile phone B. Thereafter, the mobile phone A reads out aloud the acquired location information to audibly notify the mobile phone B using a voice communication line connected to the mobile phone B.

Description

FIELD

The embodiments discussed herein are directed to mobile devices that perform call processes with other mobile devices using voice communication, location-information notification methods, and location-information notification programs.

BACKGROUND

Mobile terminals such as mobile phones that include a global positioning system (GPS) are becoming widely used, and location information such as a current location can be acquired in real time.

For example, Japanese Laid-open Patent Publication No. 2001-8254 discloses a technology in which location information is acquired using a first mobile phone, and the acquired location information is displayed on or audibly output to another mobile phone or a computer device that is connected to the first mobile phone. Specifically, the owner of the mobile phone acquires the location information of his/her mobile phone using a GPS or the like. The owner of the first mobile phone sends an image, a uniform resource locator (URL) linked to the image, audio reading of the screen, and so on as the acquired location information to the other device connected via the Internet or peer to peer (P2P) transfer by attaching the acquired location information to an email.

However, in conventional technology, there is a problem in that it is not easy to acquire the location information during a call process and it is not easy to notify a called party of this information.

Specifically describing the problem, when the location information is informed to the called party, the owner of the first mobile phone needs to view the screen, activate the GPS of the first mobile phone, and verbally inform the called party while viewing the location information acquired by the GPS or needs to end the call once, activate the GPS, and then send the location information acquired by the GPS by email. Accordingly, it is not easy for the owner of the mobile phone to inform the called party of the location information because the location information has to be given verbally or the call has to be ended once.

SUMMARY

According to an aspect of an embodiment of the invention, a mobile device includes a location-information determining unit that determines location information of the mobile device during a call; and a location-information notification unit that notifies the determined location information to a destination device of the call.

The object and advantages of the embodiment 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 embodiment, as claimed.

DESCRIPTION OF EMBODIMENTS

Preferred embodiments of the present invention will be explained with reference to accompanying drawings. In the following description, main terms used in the embodiments, the outline and features of mobile phones according to the embodiments, the configuration of the mobile phones, and a flow of processing thereof are described in this order, and then various modifications of the embodiments are described.

[a] First Embodiment

Explanation of terms

First, main terms used in the embodiment are described. The mobile phone A and mobile phone B, which are mobile devices, used in the embodiment each represent a computer device that is capable of audibly communicating, and specifically corresponds to a personal computer or a workstation that is capable of audibly communicating, a game console for a home use, an internet TV, a mobile communication terminal such as a PDA or a PHS, and the like. Each of the mobile phone A and the mobile phone B has a GPS function and is capable of acquiring detailed location information using a GPS satellite.

Outline and Features of the Mobile Phones

Next, the outline and features of the mobile phones according to the first embodiment are described with reference to FIG. 1. FIG. 1 is a schematic diagram illustrating the outline and features of the mobile phones according to the first embodiment. As illustrated in FIG. 1, the mobile phone A and the mobile phone B are devices capable of audibly performing a call process. In this specification, both mobile phones A and B are assumed to be already connected for voice communication.

With such a configuration, as described above, the mobile phone A performs the call process on the mobile phone B using voice communication, and, in particular, the mobile phone A has a feature in that it easily acquires the location information during the call process and easily notifies the called party of the location information.

The main features thereof are specifically described below. The mobile phone A determines the location information when an instruction to determine the location information about the location of the mobile phone A is received from the owner of the mobile phone A during the call process to the mobile phone B (see (1) to (4) in FIG. 1). Specifically, the mobile phone A receives, from the owner of the mobile phone A, the instruction to, for example, click a start button of a GPS function during the call process to the mobile phone B as the instruction to determine the location information about the location of the mobile phone A. Then, the mobile phone A activates the GPS function and starts determining the location information using a GPS satellite. The mobile phone A acquires the location information (for example, an email address such as Nakahara-ku, Kawasaki City, Kanagawa Prefecture . . . ) determined using the GPS satellite. The location information that can be acquired here includes cities, towns, and villages as well as the name of a station nearby the current location and information about nearby landmarks.

Thereafter, when the location information is determined by the GPS, the mobile phone A notifies the determined location information to the mobile phone B, which is the destination device in the call process (see (5) in FIG. 1). A specific explanation using the above-mentioned example is described. Using a voice communication line that is connected to the mobile phone B, the mobile phone A notifies the mobile phone B, which is the destination device in the call process, by reading out aloud the location information (Nakahara-ku, Kawasaki City, Kanagawa Prefecture) determined by the GPS.

In this way, with the mobile phone A according to the first embodiment, to acquire the current location information, there is no need for the owner of the mobile phone A to end the call process to the mobile phone B and no need to read aloud the acquired location information by himself or herself. Consequently, as the main futures described above, it is possible to easily acquire the location information during the call process and easily notify it to the called party.

Configuration of the Mobile Phone A

Next, the configuration of the mobile phone A illustrated in FIG. 1 is described with reference to FIG. 2. FIG. 2 is a block diagram illustrating the configuration of the mobile phone A. Because the mobile phone A and the mobile phone B have the same function, a detailed description is given only to the mobile phone A here.

As illustrated in FIG. 2, a mobile phone A 10 includes a communication control I/F unit 11, an input receiving unit 12, an output unit 13, a storing unit 20, and a control unit 30.

The communication control I/F unit 11 controls communication of various kinds of information exchanged with the other mobile phones or via the Internet. Specifically, the communication control I/F unit 11 controls various kinds of information about voice communication with the mobile phone B that is another mobile phone or various kinds of information about the internet communication or email communication connected using the later-described control unit 30.

The input receiving unit 12 includes a numeric keypad, a microphone, and the like and receives various kinds of information. For example, the input receiving unit 12 receives an instruction to determine the location information about the location of the mobile phone A from the owner of the mobile phone A and inputs data.

The information containing various kinds of data and parameters indicated here can be arbitrarily changed unless otherwise noted.

The email DB 22 stores sent/received emails by associating them with sent/received dates and destinations. Specifically, the email DB 22 stores emails by sorting them into, for example, incoming, outgoing, and deleted items, each corresponding to “incoming email” for saving received emails, “sent email” for saving sent emails, and “trash box” for saving deleted emails. The information containing various kinds of data and parameters indicated here can be arbitrarily changed unless otherwise noted.

The location information DB 23 stores location information acquired using a later-described GPS processing unit 35. Specifically, the location information DB 23 stores the location information acquired by the GPS processing unit 35 as character data (for example, Nakahara-ku, Kawasaki City, Kanagawa Prefecture . . . ) or map data.

The control unit 30 has a control program such as an operating system (OS) and an internal memory for storing needed data and programs prescribing various kinds of procedures and also includes a phonebook processing unit 31, a call processing unit 32, a browser processing unit 33, an email processing unit 34, the GPS processing unit 35, and a screen-reading processing unit 36, which execute various kinds of processes.

The phonebook processing unit 31 registers telephone numbers in the phonebook DB 21 in response to instructions from the owner. Specifically, when the input receiving unit 12 receives an instruction to register a telephone number or an email address from the owner, the phonebook processing unit 31 registers, in the phonebook DB 21, the new telephone number or the new email address received from the owner by the input receiving unit 12. When the input receiving unit 12 receives an instruction to delete a telephone number or an email address from the owner, the phonebook processing unit 31 deletes the telephone number or the email address to be deleted from the phonebook DB 21. When the input receiving unit 12 receives an instruction to search for a telephone number or an email address from the owner, the phonebook processing unit 31 displays on the output unit 13 the telephone number or the email address stored in the phonebook DB 21.

The call processing unit 32 controls of connecting voice communication (call process) with another telephone apparatus. Specifically, using the telephone number stored in the phonebook DB 21, the call processing unit 32 performs a process for making a call to the telephone such as a mobile phone or an IP telephone associated with the telephone number or performs a process for receiving a call from another telephone.

The browser processing unit 33 performs various controls of browsers connected to the Internet. Specifically, when the input receiving unit 12 receives an instruction to connect to the Internet from the owner, the browser processing unit 33 activates an Internet-connection browser to connect to the Internet and downloads various kinds of information and the like.

The email processing unit 34 performs various controls of sending and receiving emails. Specifically, when the input receiving unit 12 receives an instruction to send an email from the owner, the email processing unit 34 sends the email created by the owner to the destination and stores the sent email in the email DB 22, and when emails are received from other devices, the email processing unit 34 stores the received emails in the email DB 22.

The GPS processing unit 35 determines location information when an instruction to determine the location information about the location of the mobile phone A 10 is received from the owner of the mobile phone A 10 during a call process to the other apparatus. Specifically, the GPS processing unit 35 determines the location information using the GPS when the instruction to determine the location information about the location of the mobile phone A 10 is received from the owner of the mobile phone A 10.

A specific description is given using various screens output from the output unit 13. As illustrated in (1) of FIG. 3, when the input receiving unit 12 receives an instruction to acquire the location information during the call process between the mobile phone A 10 and the mobile phone B, the GPS processing unit 35 displays the “submenu” screen illustrated in (2) of FIG. 3 on the output unit 13.

Specifically, when the GPS processing unit 35 determines the location information (for example, Nakahara-ku, Kawasaki City, Kanagawa Prefecture, or the like), the screen-reading processing unit 36 reads out aloud the determined location information (for example, Nakahara-ku, Kawasaki City, Kanagawa Prefecture, or the like) to notify the called party's mobile phone B in the call process, using the same line connected for the call. The screen-reading processing unit 36 may be referred to as a “location-information notification unit”.

Processes Performed by the Mobile Phone A

Next, a process performed by the mobile phone A 10 is described with reference to FIG. 4. FIG. 4 is a flowchart illustrating a location-information notification process performed by the mobile phone A according to the first embodiment.

As illustrated in FIG. 4, when the input receiving unit 12 receives an instruction to determine the location information from the owner (Yes at Step S401), the GPS processing unit 35 in the mobile phone A 10 determines the location information about the location of the mobile phone A 10 using the GPS (Step S402).

The GPS processing unit 35 acquires the location information determined by the GPS satellite (Step S403) and displays the acquired location information (for example, character data, image data, and the like) on the output unit 13 (Step S404).

Thereafter, the screen-reading processing unit 36 reads out aloud the determined location information to audibly notify the called party's mobile phone B in the call process, using the same line connected for the call (Yes at Step 5405 and Step S406).

Advantage of the First Embodiment

In this way, according to the first embodiment, because the location information about the location of the mobile device is determined during the call process to the mobile phone B and during the phone conversation, and the determined location information is notified to the mobile phone B, which is the destination device of the call, it is possible to easily acquire the location information during the call process and easily notify the called party.

For example, to acquire the current location information, because there is no need for the owner of the mobile phone A to end the call process to the mobile phone B and no need to read out aloud the acquired location information by himself or herself, it is possible to easily acquire the location information during the call process and easily notify the called party.

Furthermore, according to the first embodiment, when an instruction to determine the location information about the location of the mobile phone A 10 is received from the owner of the mobile phone A 10, because the location information is determined using the GPS, accurate location information can be acquired.

Furthermore, according to the first embodiment, when the location information is determined, because the determined location information is read out aloud to audibly notify the called party's mobile phone B in the call process, the location information can be accurately informed of the called party in a simple notification manner.

[b] Second Embodiment

In the first embodiment, a case in which the determined location information is read out aloud to audibly notify to the mobile phone B that is connected for the call is described; however, the present invention is not limited thereto. It is possible to notify the mobile phone B connected to the call by email.

In a second embodiment, a case in which the determined location information is notified to the mobile phone B connected for the call by email is described with reference to FIGS. 5 and 6.

When the owner selects the “send current location” on the “submenu” screen, as illustrated in (3) of FIG. 5, the mobile phone A displays an email address of the mobile phone B that is connected for the call. If a plurality of email addresses are displayed, the mobile phone A receives the email address selected by the owner or automatically selects the email address of the currently connected terminal by referring to a domain name.

When the email address is automatically selected or selected by the owner, as illustrated in (4) of FIG. 5, the mobile phone A displays the “determining” screen on the output unit 13, activates the GPS, and sends an instruction to acquire the location information to the GPS satellite. Thereafter, when the GPS satellite determines the location information and when the determined location information is sent to the mobile phone A, as illustrated in (5) of FIG. 5, the mobile phone A sends an email, by attaching the acquired location information, to the mobile phone B as the destination whose email address is selected in (3) of FIG. 5.

In this way, when the location information is determined by the GPS, the mobile phone A according to the second embodiment can notify the determined location information to the called party's mobile phone B that is in the call process by email by attaching the determined location information to the email.

Flow of a Location Information Notification Process

FIG. 6 is a flowchart illustrating a location-information notification process for the mobile phone A according to the second embodiment. As illustrated in FIG. 6, when an instruction to determine the location information is received from the owner (Yes at Step S601), the mobile phone A 10 determines whether a plurality of email addresses of the mobile phone B, which is a call destination, are stored in the phonebook DB 21 (Step S602).

If the plurality of email addresses of the mobile phone B are stored in the phonebook DB 21 (Yes at Step S602), the mobile phone A displays the stored plurality of email addresses, receives the email address selected by the owner (Step S603), and determines the location information about the location of the mobile phone A 10 using the GPS (Step S604).

On the other hand, if the plurality of email addresses of the mobile phone B is not stored in the phonebook DB 21 (No at Step S602), the mobile phone A determines the location information about the location of the mobile phone A 10 using the GPS (Step S604).

The mobile phone A creates an outgoing email to which the location information determined by the GPS satellite is attached (Step S605) and sends the created outgoing email to the mobile phone B, which is the destination of the email (Step S606).

Advantage of the Second Embodiment

In this way, when the location information is determined by the GPS, because the mobile phone A according to the second embodiment notifies, by email, the mobile phone B, which is the destination device in the call process, of the determined location information by attaching it to the email, the location information can be accurately informed of the called party in a simple notification manner.

[c] Third Embodiment
