Description

  The present invention relates to a mobile terminal device, and more particularly to a mobile terminal device using a roaming service.

  In mobile phones, for example, when used in foreign countries, roaming is often performed. Roaming means that the services of a contracted telecommunications carrier can be received using the facilities of other affiliated telecommunications carriers even outside the service range of the telecommunications carrier. . If you use the international roaming service, you can receive the service overseas using the facilities of the local carrier.

  The service using the roaming starts the authentication process with the function of the USIM (User Subscriber Identity Module) card, connects to the roaming destination operator, completes the authentication, returns the operator information to the mobile phone, and uses the mobile phone. It can be used by obtaining operator information of the roaming destination. When the roaming destination has a time difference from the home country, the mobile phone clock is often corrected to the roaming destination time.

However, the following problems can be considered in existing mobile phones.
For example, since the operator corrects the roaming destination time when there is a time difference, it may be necessary to make a call while paying attention to the time other than the roaming country when calling outside the roaming country.

  In addition, the existing mobile phone functions are based on the premise that utterances to the home country and other countries are made from the roaming destination if a service contract is made, and even if the operator does not intend to connect, It is considered necessary to pay a usage fee. The same applies to the Web function, the mail function, and the answering machine function.

  In addition, since functions that are the same as when you are in your country can be used at many roaming destinations, if you are not always aware of the usage fee when using it, you may incur an unintended usage fee if you use it like your own country it is conceivable that.

As a related technique, JP 2006-246049 A (Patent Document 1) discloses a retained information correction method, an information terminal device, a mobile phone terminal device, and a control program thereof.
In this known technology, when using a mobile phone terminal device, authentication is confirmed using a control unit and a memory of a USIM card when roaming outside the home country. After confirming the authentication, the control unit checks whether there is a time difference from the roaming destination based on the operator information returned from the roaming destination, and if there is a time difference, the mobile phone based on the country code information Correct the time on the terminal device. The control unit corrects the schedule function information based on the correction time, and corrects the phone book information based on the country code information. However, in this known technique, convenience is improved by automatically converting the time and the time of the schedule function from the home country time to the roaming destination time, but the above problem has not been solved yet.

Japanese Unexamined Patent Publication No. 2006-217268 (Patent Document 2) discloses a mobile phone.
In this known technique, in a mobile phone using an international roaming service, the time is measured, voice data representing the local time is synthesized, and voice data representing the local time is voice-notified to the calling telephone.

Japanese Unexamined Patent Application Publication No. 2005-124015 (Patent Document 3) discloses a mobile communication system.
In this known technique, when a mobile device is internationally roaming to an overseas network, the VLR number of the VLR in which the mobile device is located is recorded in the HLR of its own network. When there is an incoming call to the mobile device, the local time of the area where the mobile device is located is calculated by the time server based on the VLR number recorded in the HLR and notified to the caller. The sender selects connection, disconnection, or voice mail in consideration of the notified local time. Thereby, the troublesome telephone call resulting from a time difference can be prevented. In addition, the user of the mobile device can set whether or not to notify the caller of the local time of the area in which he / she is present, and when not notified, a normal call sequence is performed.

Moreover, the control part 110 speaks, when it is not an international transmission and when it is not a midnight time zone.

  Here, a description is given by taking the midnight time zone as an example, but actually, it is not limited to the midnight time zone, but may be a time zone in which utterance should be avoided. For example, there are usually times when the other party cannot talk (working hours, during class, driving, traveling by transportation, etc.). That is, the control unit 110 determines a partner based on the telephone number input by dialing, and determines whether it is a time zone in which the partner's speech should be avoided. The telephone number of the other party and the time zone in which the other party's utterance should be avoided are set in advance. The control unit 110 stores this setting information in the temporary storage unit 130.

  Further, as in the case of utterances, it may be possible to restrict mail transmission in the midnight time zone or in a time zone where utterance should be avoided. This is because it is conceivable that the ringing tone when receiving the mail causes trouble to the other party as in the case of the utterance. In this case, the control unit 110 stores the e-mail requested to be transmitted in the function restricted time zone in the temporary storage unit 130, and the time obtained from the clock unit 170 no longer corresponds to the function restricted time zone. At that time, the mail stored in the temporary storage unit 130 is transmitted.

  In addition, here, the communication between the home country and the roaming destination country is described as an example, but in actuality, it can be applied to an international roaming service in communication between other countries. For example, when speaking to a partner in another country from a roaming destination country, obtain the country code of the other country, calculate the time difference between the roaming destination country and the other country, calculate the time of the other country, It is possible to limit utterances in other countries at midnight or when it should be avoided.

  Regarding the time difference, the clock unit 170 may manage the time information of a plurality of countries in order to calculate the time difference between the roaming destination country and another country. At this time, the country code is associated with the time information of the country on a one-to-one basis. Alternatively, the temporary storage unit 130 may store a list of time differences between the roaming destination country and other countries as a data list. In this case, the time difference is also found when the country code is acquired.

  Further, as the USIM card 200 is improved in performance and functionality, it is conceivable to use the control unit 210 and the storage unit 220 instead of the control unit 110 and the storage unit 120. That is, it can be considered that the control unit 210 performs the function restriction function setting operation and the function restriction operation of the present embodiment in accordance with the control program stored in the storage unit 220.

Next, a second embodiment of the invention will be described.
Also in the second embodiment of the present invention, the same configuration as in FIG. 1 is used and the function restriction is set in the same manner as in FIGS. 2A and 2B.
With reference to FIG. 5A, FIG. 5B, and FIG. 5C, another function restriction | limiting operation | movement by control from the control part 110 is shown. Other function limiting operations are defined in the control program stored in the storage unit 120.

The control unit 310 performs a confirmation display on the display unit 350 as to whether or not the speech destination is in the midnight time zone. That is, this confirmation display becomes a warning display.
(8) Step S508
The control unit 310 executes the utterance when the utterance is OK, and ends without speaking when the utterance is not OK.
(9) Step S509
Control unit 310 utters when it is not an international call and when it is not a midnight time zone.

  Thus, in the present embodiment, it is possible to prevent the recipient from speaking into the midnight time zone. The reason is that utterances that are not conscious of the time of the utterance destination can be eliminated by calculating the utterance destination time based on the roaming information and realizing the warning display.

  In addition, as a warning display, the home country time (local time of the communication destination) and a charge per unit time required for using the roaming service may be displayed on the display unit 350.

  Here, a description is given by taking the midnight time zone as an example, but actually, it is not limited to the midnight time zone, but may be a time zone in which utterance should be avoided. For example, there are usually times when the other party cannot talk (working hours, during class, driving, traveling by transportation, etc.). That is, the control unit 310 determines the other party based on the telephone number input by dialing, and determines whether it is a time zone in which the other party's utterance should be avoided. The telephone number of the other party and the time zone in which the other party's utterance should be avoided are set in advance. The control unit 310 stores the setting information in the temporary storage unit 330 or the telephone directory storage unit 380.

  Further, as the USIM card 400 is improved in performance and functionality, it is conceivable to use the control unit 410 and the storage unit 420 instead of the control unit 310 and the storage unit 340. That is, it is conceivable that the control unit 410 performs the speech restriction operation of this embodiment according to the control program stored in the storage unit 420.

  As described above, in the present invention, roaming is performed by a known technique for overseas use, and the home time can be obtained at the roaming destination from the operator information (country code, time difference) obtained by roaming authentication. It is characterized by improved convenience at roaming destinations by providing utterance warnings for late-night time at home time and connection restriction / connection warnings to home operator service functions.

  In the present invention, when using in a roaming destination country, when trying to make a call from the roaming destination country when there is a time difference between the roaming destination country and the home country, a warning or restriction is given if the call is made unconsciously. By doing so, consideration is given to the recipient.

  Further, in the present invention, unintentional usage charges are prevented by unintentionally restricting the use of functions or issuing a warning in the country of roaming as in the country.
