Particular illustrative embodiments will now be described more fully with reference to the drawings. One or more exemplary embodiments may be embodied in many different forms and should not be construed as being limited to the illustrative embodiments set forth herein. Rather, the exemplary embodiments described herein are provided so that this invention will be thorough and complete, and the concept of one or more exemplary embodiments will be fully conveyed to those skilled in the art. In the following description, well-known functions or constructions may not be described in detail, as the description of one or more exemplary embodiments will be confused in unnecessary detail, and similar reference numbers in the drawings represent similar or Similar components.

In the present specification, when a zone is "connected" to another zone, the zone may be "directly connected" and may be "electrically connected" via another device therebetween. Also, the region may further include other components when the region "includes" the component.

The term "and/or" as used herein includes any or all of one or more of the associated listed items. When preceded by a list of components, an expression such as "at least one of" modifies the entire list of elements and does not modify the individual elements of the list.

In this specification, the execution of a telephone call includes both receiving a call and making a call.

Hereinafter, one or more exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram for describing a mobile communication system 1 in which different mobile devices make calls using the same telephone number, in accordance with an exemplary embodiment.

Referring to FIG. 1, the mobile communication system 1 includes a server 10 for moving a carrier, a first mobile device 20 of the user A, a second mobile device 30 of the user A, and a mobile device 40 of the 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 can be two types of devices. 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 phone, but one or more exemplary embodiments are not limited thereto. The card type telephone will be described in detail with reference to the drawings.

User A may have a first mobile device 20 that is a smart phone and a second mobile device 30 that is a card phone. In the mobile communication system 1, the telephone number of the first mobile device 20 and the telephone number of the second mobile device 30 are the same, that is, "+82-10-AAAA-BBBB". In other words, the first mobile device 20 and the second mobile device 30 can share a particular phone number.

Therefore, when the user B dials "+82-10-AAAA-BBBB" using the mobile device 40, the user A can use the first mobile device 20 or the second mobile device 30 to talk to the user B.

A mobile bearer represents any entity capable of providing mobile communication services, such as South Korea's SK Telecom and KT, as well as Verizon Wireless, AT&T, Sprint Nextel and T-Mobile USA in the United States of America. The server 10 of the mobile carrier may represent a server operated by the mobile carrier to provide mobile communication services to the consumer.

The server 10 of the mobile carrier can determine that the phone number "+82-10-XXXX-XXXX" is currently assigned to the mobile device 40 of the user B. Further, the server 10 of the mobile carrier can determine that one of the first mobile device 20 and the second mobile device 30 of the user A is currently assigned a telephone number "+82-10-AAAA-BBBB".

When the mobile device 40 assigned the telephone number "+82-10-XXXX-XXXX" calls the telephone number "+82-10-AAAA-BBBB", the server 10 of the mobile carrier can relay the telephone call to the assigned telephone. The first mobile device 20 or the second mobile device 30 of the number "+82-10-AAAA-BBBB".

In other words, both the first and second mobile devices 20 and 30 can perform the mobile communication function by subscribing to the mobile communication system 1 without having to assign 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, that is, the first and second mobile devices 20 and 30, but this case is only an example, and the user A can have the same phone. Two or more mobile devices of the number.

2 is a schematic diagram of a second mobile device 30 of user A, in accordance with an illustrative embodiment.

Referring to FIG. 2, the second mobile device 30 can be a card phone having a shape different from that of a smart phone. A card type telephone can represent a mobile communication function having a smart phone type and an ultra-fine or ultra-thin shape mobile device similar to a credit card or a traffic card. In other words, similar to a smart phone, a card phone can be assigned an electric The phone number and the telephone call with another phone is performed via the mobile communication system 1. For example, since only the ultra-small module is mounted on the card phone to make the card phone ultra-fine, among the various functions of the smart phone, the card phone can perform only simple functions such as a phone function or Input/output functions, but one or more exemplary embodiments are not limited thereto.

FIG. 25 is a diagram for describing synchronization of a recent call history between a first mobile device 20 and a second mobile device 30, according to an exemplary embodiment.

As described above, the first and second mobile devices 20 are separate devices capable of making and receiving telephone calls. Thus, the history of telephone calls made and received by the first mobile device 20 may be stored only in the first mobile device 20, and the history of telephone calls made and received by the second mobile device 30 may be stored only in the second mobile device. 30 in. However, because the first and second mobile devices 20 and 30 share a phone number, Therefore, the recent call history of the first and second mobile devices 20 and 30 can be synchronized for user convenience.

The point in time at which the recent call history is synchronized may be when the first and second mobile devices 20 and 30 are separated from each other or connected to each other, but one or more exemplary embodiments are not limited thereto, and may be synchronized at any time desired by the user. Recent call history.

FIG. 26 is a flowchart of a method of synchronizing recent call history when the first mobile device 20 and the second mobile device 30 are separated from each other, according to an exemplary embodiment.

Referring to Figure 26, the separation of the first and second mobile devices 20 and 30 may mean that the user wants to use the second mobile device 30 (e.g., a card phone) instead of the first mobile device 20 (e.g., a smart phone).

In operation 2601, the first mobile device 20 stores the most recent call history for the most recent telephone call until the last telephone call when connected to the second mobile device 30.
