DETAILED DESCRIPTION

Certain exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, one or more exemplary embodiments may be embodied in many different forms, and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, the exemplary embodiments described herein are provided so that this disclosure will be thorough and complete, and will fully convey the concept of one or more exemplary embodiments to those of ordinary skill in the art. In the following description, well-known functions or constructions may not be described in detail since they would obscure the description of one or more exemplary embodiments with unnecessary detail, and like reference numerals in the drawings denote like or similar elements throughout the specification.
In the specification, when a region is “connected” to another region, the regions may not only be “directly connected,” but may also be “electrically connected” via another device therebetween. Also, when a region “includes” an element, the region may further include other elements.
As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
In the specification, performing of a phone call includes both receiving a call and making a call.
Hereinafter, one or more exemplary embodiments will be described in detail with reference to accompanying drawings.
FIG. 1 is a diagram for describing a mobile communication system 1 in which different mobile devices make a call using a same phone number, according to an exemplary embodiment.
Referring to FIG. 1, the mobile communication system 1 includes a server 10 of a mobile carrier, a first mobile device 20 of a user A, a second mobile device 30 of the user A, and a mobile device 40 of a user B. In the mobile communication system 1, the first mobile device 20, the second mobile device 30, and the mobile device 40 may each be a device having a mobile communication function, such as a smart phone, a tablet device, or a personal digital assistant (PDA). For example, the first and second mobile devices 20 and 30 may be two types of device. Hereinafter, for example, it is assumed that the first mobile device 20 is a smart phone and the second mobile device 30 is a card-type phone, but one or more exemplary embodiments are not limited thereto. The card-type phone will be described in detail with reference to accompanying drawings.
The user A may own the first mobile device 20 that is a smart phone and the second mobile device 30 that is a card-type phone. In the mobile communication system 1, a phone number of the first mobile device 20 and a phone number of the second mobile device 30 are the same, i.e., “+82-10-AAAA-BBBB.” In other words, the first mobile device 20 and the second mobile device 30 may share a certain phone number.
Accordingly, when the user B dials “+82-10-AAAA-BBBB” using the mobile device 40, the user A may talk to the user B using the first mobile device 20 or the second mobile device 30.
The mobile carrier denotes any entity capable of providing mobile communication services, such as SK Telecom and KT in the Republic of Korea, and Verizon Wireless, AT&T, Sprint Nextel, and T-Mobile USA in the United States of America. The server 10 of the mobile carrier may denote a server operated by the mobile carrier to provide a mobile communication service to consumers.
The server 10 of the mobile carrier may determine that a phone number “+82-10-XXXX-XXXX” is currently assigned to the mobile device 40 of the user B. Also, the server 10 of the mobile carrier may determine that one phone number “+82-10-AAAA-BBBB” is currently assigned to both the first mobile device 20 and the second mobile device 30 of the user A.
When the mobile device 40 assigned with the phone number “+82-10-XXXX-XXXX” calls the phone number “+82-10-AAAA-BBBB,” the server 10 of the mobile carrier may relay a phone call to the first mobile device 20 or the second mobile device 30 assigned with the phone number “+82-10-AAAA-BBBB”.
In other words, the first and second mobile devices 20 and 30 may both perform a mobile communication function by being subscribed to the mobile communication system 1, without having to be assigned different phone numbers by the server 10 of the mobile carrier. Meanwhile, in FIG. 1, the number of mobile devices owned by the user A is two, i.e., the first and second mobile devices 20 and 30, but this is only an example, and the user A may own two or more mobile devices having the same phone number.
FIG. 2 is a diagram of the second mobile device 30 of the user A, according to an exemplary embodiment.
Referring to FIG. 2, the second mobile device 30 may be a card-type phone having a different shape from a smart phone. The card-type phone may denote a mobile device having a mobile communication function like a smart phone, while having an ultra-slim or ultra-thin shape like a credit card or a transportation card. In other words, like a smart phone, the card-type phone may be assigned with a phone number and perform a phone call with another phone through the mobile communication system 1. For example, since only subminiature modules are mounted on the card-type phone such that the card-type phone is ultra-slim, the card-type phone may only perform simple functions, such as a phone function or input/output functions, from among various functions of a smart phone, but one or more exemplary embodiments are not limited thereto.
The second mobile device 30 realized as the card-type phone may include, for example, a display 311, e.g., a display unit, and an input interface 313, e.g., an input unit, on a front surface.
The display 311 may display information input through the input interface 313. For example, the display 311 may display numbers input through a keypad of the input interface 313, a contact list stored in the second mobile device 30, or caller information of a received phone call. The display device 311 may perform a function of displaying various types of information processed by the second mobile device 30.
The input interface 313 may be a keypad having physical buttons. The input interface 313 may be a keypad including, as non-limiting examples, number buttons, a call connection button, and a call termination button, and the like.
FIG. 3 is a diagram of the second mobile device 30 of the user A, according to another exemplary embodiment.
Referring to FIG. 3, the second mobile device 30 of FIG. 3 may include a touch screen 315 on a front surface. The second mobile device 30 of FIG. 3 is realized as a card-type phone that includes the touch screen 315 in which functions of the display 311 and the input interface 313 are integrated.
Accordingly, the second mobile device 30 of FIG. 3 realized as the card-type phone may receive a number or a character via a soft keyboard displayed on the touch screen 315, and may display various types of information processed by the second mobile device 30, such as a contact list or caller information of a received phone call, through the touch screen 315.
A card-type phone is not limited to the above description, and may be realized with various elements and features.

Meanwhile, not only the first mobile device 20, but also the second mobile device 30 may manage a recent call history of the second mobile device 30 using an index (or a sync index).
In operation 2805, the second mobile device 30 determines whether the index received from the first mobile device 20 is the same as an index of the last phone call of the second mobile device 30. In other words, the second mobile device 30 may determine whether the recent call histories of the first and second mobile devices 20 and 30 are different from each other based on the received index, or whether the recent call histories of the first and second mobile devices 20 and 30 need to be synchronized. When the indexes are the same, the method is ended since the recent call histories do not need to be synchronized. When the indexes are not the same, operation 2806 is performed.
In operation 2806, the second mobile device 30 generates information about a phone call history after the index received from the first mobile device 20.
