2. Description of the Related Art
Under the current trend of globalization, international business activities or tourism activities are getting more and more popular, and many people need to travel domestically or internationally for their business or tourism. Thus, when the user makes a phone call, quite often the user cannot make sure whether the receiver stays domestically or has gone overseas. If the user makes a domestic phone call but the receiver is already overseas, international roaming rate applies. In general, international roaming rate is very expensive and this is quite a nuisance to both the caller and the receiver.
The invention is directed to a method, a communication device, and a storage device for controlling communication. A comparison between the original area corresponding to the telephone number and the actual location of the receiver is made for determining whether the receiver is in the original area corresponding to the number or other areas.
According to a first aspect of the invention, a communication controlling method is provided. The communication controlling method comprises the following steps. A telephone number of a receiver is provided, wherein the telephone number is corresponding to a first area. A second area where the receiver is located is provided. Whether the first and second areas are the same is determined. If the first and second areas are not the same, then a warning message is displayed.
According to a second aspect of the invention, a communication device is provided. The communication device comprises a storage unit, a processing unit, and a display unit. The storage unit stores a telephone number of a receiver and a second area where the receiver is located. The telephone number is corresponding to a first area. The processing unit determines whether the first and second areas are the same. The display unit is controlled by the processing unit to display a warning message if the first and second areas are not the same.
According to a third aspect of the invention, a storage device is provided. The storage device loads in a computer program for performing the following steps. A telephone number of a receiver is provided, wherein the telephone number is corresponding to a first area. A second area where the receiver is located is provided. Whether the first and second areas are the same is determined. If the first and second areas are not the same, then a warning message is displayed.
The above and other aspects of the invention will become better understood with regard to the following detailed description of the preferred but non-limiting embodiment(s). The following description is made with reference to the accompanying drawings.

Firstly, the method begins at step S201, the user provides a telephone number of a receiver (not illustrated) via an input interface 110, wherein the area corresponding to the telephone number is defined as a first area, which covers a specific range such as one or several cities, a region of a country, a country, and a number of adjacent countries. For example, when the range of the area is a country, (the national code for Taiwan is “+886”, and the national code for the United States is “+1”), the corresponding country of the telephone number (that is, the area corresponding to the telephone number) can be identified from the country codes (for example the national code “+886” and “+1”).
Next, the method proceeds to step S202, a second area where the receiver is located is provided. In the present step, the second area may be pre-stored in the storage unit 120, for example, the user may input the receiver location to the receiver's contact data. Or, the second area may be obtained by retrieving the receiver's calendar information from the communication device or the calendar of the network application program, then the processing unit 130 retrieves the second area from the storage unit 120. Or, the second area may be instantaneously obtained by detecting the receiver's current location detected with the communication unit 150 and then performing the location sharing function. The location sharing application program is such as a network service and an application program capable of sharing and updating its own location, or an application program capable of sharing information with other users. Or, the second area may be obtained by inquiring the receiver via the network. In the present embodiment of the invention, the storage unit 120 may store the mapping tables between various types of geographic information and area information, so that the corresponding area may be obtained when obtaining various types of geographic information. Examples of the mapping table comprise a mapping table between latitude/longitude and area information, a mapping table between base stations and area information, a mapping table between WiFi hotspots and area information, a mapping table between national codes and countries, a mapping table between telephone area numbers and area information, a mapping table between addresses and area information, and a mapping table between electronic map location and area information, and no specific restriction is imposed here.
Then, the method proceeds to step S203, the processing unit 130 determines whether the first and second areas are the same. If the first area and second areas are the same, then the method directly proceeds to step S206. If the first and second areas are not the same, then the method proceeds to step S204.
In an embodiment, steps S202 and S203 may be halted until the user presses the call key or performs call function after the user has inputted and provided a telephone number of a receiver. In another embodiment, steps S202 and S203 may be performed at the same time when the user inputs and provides the receiver's telephone number. For example, when the user inputs and provides the receiver's telephone number, the contact data is compared at the same time so as to locate the corresponding contact person and retrieve the second area of the receiver's contact person from the corresponding contact data for performing steps S202 and S203.
In step S204, the processing unit 130 controls the display unit 140 to display a warning message S1. Referring to
Next, the method proceeds to step S205, whether the call confirmation option S11 is activated is determined by the processing unit 130. If the call confirmation option S11 is activated, then the method proceeds to step S206. If the call confirmation option S11 is not activated, the window of the warning message S1 is closed, a reject option (not illustrated in the diagram) is activated, or a hang-up key is activated, then the method terminates.
In step S206, the processing unit 130 controls the communication unit 150 to dial the telephone number.
Through the above steps, user can immediately understand whether the receiver has left the corresponding area of the telephone number when the caller is about to make a phone call to the receiver. If the user finds that the receiver has left the corresponding area of the telephone number and no more stays in the area that the user thought to be, the user may choose not to dial the telephone number, lest one party or both parties has to pay expensive roaming fee. If the user still wants to make the phone call despite it is a roaming call, the user will be aware of the roaming call and control the call time accordingly.
Referring to
In general, when the receiver logs in a particular network service (websites such as Google Latitude, Google Map, Facebook), the server of the network service may detect a geographic location in which the receiver logs in the network service. In step S401, the communication unit 150 of the communication device 100 may receive the receiver's geographic location detected by the network service.
Next, the method proceeds to step S402, the processing unit 130 of the communication device 100 defines the second area according to the above geographic location.
Then, the method proceeds to step S403, the second area is stored in the storage unit 120 by the processing unit 130.
To assure the accuracy of the receiver's second area, steps S401-S403 may be repeated each predetermined time for updating the second area stored in the storage unit 120 or the second area in the storage unit 120 may be updated instantaneously.
Thus, the receiver's second area may be pre-stored in the storage unit 120. When the communication device 100 performs step S202, the receiver's second area may be directly retrieved from the storage unit 120 without going through series of steps, so that the speed of information processing is increased.

As indicated in
Next, the method proceeds to step S505, whether the call confirmation option S21 is activated is determined by the processing unit 130. If the call confirmation option S11 is activated, then the method proceeds to step S506. If the call confirmation option S21 is not activated, then the method terminates.
In step S506, the processing unit 130 controls the communication unit 150 to send a message.
Despite the above embodiments are divided into the first embodiment and the second embodiment, the first embodiment and the second embodiment can be concurrently implemented on the same communication device 100. The first embodiment is adopted when the user performs a phone calling procedure (such as inputting a telephone number to the main frame and pressing a call key; or selecting a contact person from the telephone book and making a call). The second embodiment is adapted when the user performs a message sending procedure (such as inputting text to the message editing window and pressing the send key; or selecting a contact person from the telephone book, pressing the message editing key, and sending the message).
While the invention has been described by way of example and in terms of the embodiments, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
