Description

[0001] MOBILE COMMUNICATION DEVICE [0002]

The present invention relates to a mobile communication terminal. More specifically, the present invention relates to a mobile communication terminal having a card-mounting socket capable of mounting one or two SIM cards storing at least two or more subscriber identification information.

2. Description of the Related Art Generally, a mobile communication terminal such as a mobile phone and a PDA has not only transmitted voice information but has also provided character information, image information, game, and the like to users.

In recent years, an audio player function capable of reproducing an audio file such as an MP3 file and a digital camera function capable of shooting or listening to a digital photograph and a video have been combined with the mobile communication terminal. Accordingly, mobile communication terminals, which have been increasingly used in this way, are now becoming a necessity for daily living.

The mobile communication terminal is equipped with a subscriber identity module card to identify and identify the subscriber and provide basic user information. A SIM card or a USIM card is installed as the subscriber identity module card.

 The subscriber identity module card includes a SIM (Subscriber Identity Module) card, a Universal Subscriber Identity Module (USIM), a 0 User Identity Module (UIM) card, and a Removable User Identity Module (RUIM) card.

Such a subscriber identity module card may use the same number of mobile communication terminals by replacing the card only in some cases. For example, if the SIM card is replaced with a SIM card, any mobile communication terminal can use the SIM card as a user's own number identified by the subscriber identification information stored in the SIM card.

 Therefore, if you have a subscriber identity module card, you can borrow it if you do not even have a phone. Also, when a phone is lost or broken, the replacement phone can be used with the same number.

If the subscriber identity module card is replaced with a single mobile communication terminal by using the subscriber identity module card, it means that the same number can be used. That is, when a specific user desires to use two or more identification numbers in one terminal, the same mobile communication terminal can be used as a plurality of identification numbers by having two or more subscriber identity module cards.

In addition, in order to selectively provide GSM and CDMA mobile communication services in one mobile communication terminal, a SIM card provided by a GSM mobile communication provider for subscriber identification and a SIM card provided by a CDMA mobile communication provider for subscriber identification The mobile communication service can be selected by simultaneously mounting the card.

If the mobile communication terminal held by the user can be used for both GSM and CDMA mobile communication services, the SIM card can be selectively installed A single mobile communication terminal can be used regardless of the type of mobile communication service provider.

As described above, when the mobile communication terminal attempts to use two or more subscriber numbers or both the GSM and CDMA mobile communication services, the user can use two or more SIM cards or the like to one mobile communication terminal Or a mobile communication terminal equipped with two or more card-mounting sockets can be used.

However, it is cumbersome to selectively remove a subscriber identity module card, such as a SIM card, when necessary, and there is a risk of losing a stored SIM card or the like. In many cases, a mobile communication terminal having two or more card-mounting sockets includes a card-mounting socket for mounting a memory card in addition to a subscriber identity module card. Therefore, in order to mount a plurality of subscriber identity module cards, The wasted space inside the mobile communication terminal is wasted.

That is, it is undesirable for the design conditions of the mobile communication terminal, which is preferable for miniaturization, and the manufacturing cost may increase.

The present invention provides a mobile communication terminal having a card mounting socket capable of mounting at least one or more SIM cards stored with at least two distinct subscriber identification information.

According to an aspect of the present invention, there is provided a mobile communication terminal comprising: a card mounting socket capable of mounting one or two SIM cards storing at least two distinguishing subscriber identification information; a main board on which the card mounting socket is installed; And a housing surrounding the board.

In addition, the card-mounting socket may be provided with one SIM card in which two distinguishing subscriber identification information is stored, or two SIM cards in which one user identification information is stored, respectively, so that the subscriber identification information may be provided.

In this case, when two SIM cards are mounted, the SIM cards can be mounted on the upper and lower sides of the SIM card socket.

The card mounting socket may be provided with a card mounting socket terminal portion in which a terminal portion of the SIM card contacts the upper surface and the lower surface of the card mounting socket.

Here, the insertion direction of the SIM card inserted into the card-mounting socket may be orthogonal.

In addition, the inserting direction of the SIM card mounted in the card mounting socket may be parallel.

In this case, the card-mounting socket may have a support portion at both ends of the card-mounting socket so that the SIM card can be inserted and mounted on the bottom surface thereof.

A fixing member for fixing the SIM card mounted on the upper surface of the card mounting socket may be provided.

Here, when one SIM card is loaded, the SIM card is provided with a storage space in which two distinguishing subscriber identification information are stored independently, and a subscriber identification The card mounting socket may be provided with a terminal portion that is in contact with the terminal portion of the SIM card in the inner side surface of the card mounting socket, respectively, when the SIM card is inserted .

In this case, a step may be formed in the housing to form a SIM card slot of the card socket.

According to the mobile communication terminal of the present invention, it is possible to maximize the utilization of the mobile communication terminal by providing a mobile communication terminal capable of mounting at least one or more SIM cards stored with at least two different subscriber identification information.

Therefore, according to the mobile communication terminal of the present invention, it is possible to mount at least one or more SIM cards in which at least two distinguishing subscriber identification information are stored, and in the case of mounting two SIM cards, It is possible to minimize the volume of the mobile communication terminal.
