Description

  The present invention relates to a mobile phone communication system, a mobile phone communication method, a mobile phone, a mobile communication control station, a program, and a recording medium.

As is well known, the world time is determined by a globally standardized time (GMT: Greenwich Mean Time). In recent years, due to the development of transportation means such as airplanes and ships, there are many cases of going back and forth between the home country and foreign countries, and going back and forth within the same area. For this reason, when moving across time zones, it is necessary to reset the owned mobile phone to the current time (local time) of the destination.
Here, in principle, the time zone is obtained by dividing the earth physically by 15 ° meridians starting from Greenwich in England, but the interval between meridians differs depending on the region or country.

However, in order to correct the time setting according to the destination, it is necessary to grasp the time zone of the destination in advance and manually correct the time setting for each movement.
Also, if the person you want to call is moving to a foreign country and there is a time difference between the foreign country and your country, or if there is a time difference depending on the region within the same country, such as the United States of America, calculate the local time of the destination and call It was necessary to make extra effort to check whether it was a time zone (for example, daytime) that would not cause any problems. Furthermore, when the destination of the other party is unknown, there is a problem that it is impossible to know whether or not it is a time zone in which a call can be made with the other party.

Therefore, the clocking time of the clocking means is adjusted so as to be the local time at the position detected by the position detecting means (see, for example, Patent Document 1), or the data is corrected by country information from the base station and transferred to another country. A mobile phone that can know the local time without correcting the time by itself even when moving is disclosed (for example, see Patent Document 2).
In addition, it shifts by the time difference between moving countries and automatically corrects and corrects the alarm function to operate (see, for example, Patent Document 3), obtains the current position from GPS, calculates the local time, It is disclosed that the local time is set when is set.
Here, the daylight saving time is provided by the government of a specific country for energy saving, and is a time advanced by one hour in the summer (see, for example, Patent Document 4).
Furthermore, a wireless communication system capable of notifying the caller of the local time of the mobile terminal of the communication partner before the call and a time identification method of the mobile terminal of the partner in the caller mobile terminal have been proposed (for example, Patent Documents). 5).

  However, with the technique described in Patent Document 1 described above, the time of the other party cannot be known before a call, and the technique described in Patent Document 2 is used when the user of the mobile phone moves to a foreign country or another area. It corrects the time of the built-in clock of the user's mobile phone, the date of the calendar, and the alarm, and does not display the time (local time) of the country where the other party is located.

  In addition, although the technique described in Patent Document 3 corrects the alarm function, it cannot know the time of the other party before the call. In the techniques described in Patent Documents 4 and 5, the exchanges connected to the base station are not connected. In order to connect, a plurality of gateway exchanges and a large-capacity database are required, and the system is complicated accordingly.

  In addition, when moving across time zones, it is necessary to reset the owned mobile phone to the local time of the destination. However, in order to correct the time setting according to the destination, it is necessary to grasp the time zone of the destination in advance or to manually correct the set time every time it is moved. There is a need for a function that automatically sets the time zone and daylight saving time.

Also, when the person you want to call moves to a foreign country or region with a time difference, it is unnecessary to calculate the time of the destination (local time) and check whether it is a time when there is no problem even if you make a call. It took effort. In addition, when the destination of the other party is unknown, there is a problem that it is not possible to know whether or not it is a time zone in which the other party can talk.
