Description

How to display time when roaming mobile phone {Time displaying method at roaming for mobile phone}

The present invention relates to a method of displaying a time when roaming a mobile phone, and particularly, a mobile phone which automatically calculates and displays a home time, which is the current time of an original service area, to be notified to a user when a time zone moves to another service area and roams Relates to a time display method when roaming.

In recent years, the mobile communication technology that transmits and receives information wirelessly has made remarkable development, and accordingly, the mobile communication terminal has made a lot of developments. At present, the present situation is developing a terminal capable of a video call.

Such a mobile phone can be used in a region where a user subscribes to a service of an operator providing a mobile communication service. Generally, each country has a slightly different situation, but there are several mobile communication service providers, and each of them provides a service within a certain region. In this case, if a service provider provides a mobile communication service to all the territories due to its small territory, such as Korea, it is not necessary.However, there are many operators such as the United States and China, but they are not provided all over the territory. In the case of providing a service in a certain region or moving between countries, a service provider of a mobile communication service that can be provided in the region is different and a roaming service is required. That is, roaming refers to a service that enables communication even when a customer moves to an area beyond a subscription network by connecting a wireless network between operators having different service areas in mobile communication, thereby allowing payment of a fee.

This roaming service is performed by the following procedure. For example, if a user joins the operator A's network and moves to the operator B's network area to apply for roaming, the user's mobile terminal requests registration and authentication of the operator A's network. The provider B's network requests the subscriber's information from the provider A's network. The provider A's network that receives the subscriber's information request sends the subscriber information and authentication information to the provider B's network, and performs roaming registration and routing information management therein. The provider B network receiving the subscriber information allows roaming, transmits various types of information, and manages subscriber information, location information, and authentication information related to the roaming applicant. When the roaming procedure is completed, the user can use the network in the operator B's network area to transmit and receive telephone calls or information. On the other hand, such roaming may occur in one country as described above, but may be particularly useful when the user moves the country.

In general, when a user turns on the mobile phone while the mobile phone is turned off within the network area he subscribed to, the mobile phone signals the subscribed network to register its location in the network and receive various other information. . In this case, the home time, which is usually information about the current time of the region, is input and displayed through the display unit of the mobile phone. Therefore, when the user moves to another network area and roams, the user receives the information about the local time, which is the current time of the area, and informs the user of the local time, which is the time of the current location.

However, the conventional method of displaying the time when roaming a mobile phone displays the local time of the region, especially when the user moves between countries with different time zones. There is a problem that a user needs to calculate. This problem is very inconvenient because when the user travels to a different country and frequently communicates with the headquarters of the network area to which he / she subscribes, he often has to calculate information about home time by himself.

The present invention has been made to solve the above-described problems of the prior art, when the user moves to another area when a difference occurs between the home time and local time is input to the information about the local time of the local home time automatically Its purpose is to provide a method for displaying the time when roaming a mobile phone that can inform the user by calculating.
