Description:
RELATED APPLICATION(S) 
       [0001]    This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed in the Korean Intellectual Property Office on Aug. 13, 2014 and assigned Serial No. 10-2014-0104942, the entire disclosure of which is incorporated herein by reference. 
       BACKGROUND 
       [0002]    Various embodiments of the present disclosure relate to a method and apparatus for inputting information about a device interworking with a second device when the devices interwork with each other for short-range communication. 
         [0003]    To meet the demand for wireless data traffic having increased since deployment of 4G (4 th -Generation) communication systems, efforts have been made to develop an improved 5G (5 th -Generation) or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a ‘Beyond 4G Network’ or a ‘Post LTE System’. The 5G communication system is considered to be implemented in higher frequency (mmWave) bands, e.g., 60 GHz bands, so as to accomplish higher data rates. To decrease propagation loss of the radio waves and increase the transmission distance, the beamforming, massive multiple-input multiple-output (MIMO), Full Dimensional MIMO (FD-MIMO), array antenna, an analog beam forming, large scale antenna techniques are discussed in 5G communication systems. In addition, in 5G communication systems, development for system network improvement is under way based on advanced small cells, cloud Radio Access Networks (RANs), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, Coordinated Multi-Points (CoMP), reception-end interference cancellation and the like. In the 5G system, Hybrid FSK and QAM Modulation (FQAM) and sliding window superposition coding (SWSC) as an advanced coding modulation (ACM), and filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as an advanced access technology have been developed. 
         [0004]    The Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of Things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of Everything (IoE), which is a combination of the IoT technology and the Big Data processing technology through connection with a cloud server, has emerged. As technology elements, such as “sensing technology”, “wired/wireless communication and network infrastructure”, “service interface technology”, and “Security technology” have been demanded for IoT implementation, a sensor network, a Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and so forth have been recently researched. Such an IoT environment may provide intelligent Internet technology services that create a new value to human life by collecting and analyzing data generated among connected things. IoT may be applied to a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services through convergence and combination between existing Information Technology (IT) and various industrial applications. 
         [0005]    In line with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, technologies such as a sensor network, Machine Type Communication (MTC), and Machine-to-Machine (M2M) communication may be implemented by beamforming, MIMO, and array antennas. Application of a cloud Radio Access Network (RAN) as the above-described Big Data processing technology may also be considered to be as an example of convergence between the 5G technology and the IoT technology. 
         [0006]    Smartphones used in recent times basically provide short-range wireless communication which is one of technical standards for data communication within a short range, such as Bluetooth, Wireless Fidelity (Wi-Fi), Near Field Communication (NFC), and so forth. 
         [0007]    Bluetooth is a short-range wireless communication network that is available within a short range of about 10 meters (m). Due to its low price and low power consumption compared to other techniques, Bluetooth is basically mounted in most smartphone devices. Bluetooth connects a wireless device such as a headphone, a keyboard, or the like, and/or transmits data. To use Bluetooth for data communication, communication devices are registered with each other through a pairing procedure. In a Bluetooth pairing process, a terminal operating as a master device detects devices that may be paired, selects a device to be paired from among the detected devices, and performs pairing with the selected device. 
         [0008]    Wi-Fi, which is frequently used in wireless Internet access of a smartphone, is a data technique for transmitting and receiving radio data using a Wireless Local Area Network (WLAN). In particular, an Access Point (AP) may be installed at home simply by installing a wireless Internet router, such that wireless communication is possible within a radius of up to 10-20 m. Moreover, Wi-Fi Direct transmits and receives data by wirelessly accessing another device without an AP, and thus is mainly used to exchange data between smart devices supporting Wi-Fi Direct. Because of having a broader transmission radius and a higher speed than Bluetooth, Wi-Fi Direct may be widely used in various forms such as a wireless printer, a smart TV, a fighting game, and so forth. When a terminal accesses a Wi-Fi AP, the terminal has to input a password or a Medium Access Control (MAC) address of an access-allowed device is registered in the Wi-Fi AP in advance to restrict an access of an unauthorized terminal to the Wi-Fi AP. 
         [0009]      FIG. 1  illustrates an example of a procedure for providing interworking between devices for short-range communication according to conventional art. 
         [0010]    Referring to  FIG. 1 , a distributor  101  creates an identifier, for example, a Quick Response (QR) code, for a new device  103  before delivering the new device  103  to a purchaser (that is, a user) purchasing the new device  103 , gives the identifier to the new device  103 , sets the new device  103  to an Internet-connectable state for interworking with Cloud  105  provided by a manufacturer or the distributor  101 , and then delivers the new device  103  to the purchaser. Once the purchaser having received the new device  103  turns on the new device  103 , the new device  103  is connected to the Cloud  105  according to preset information and scans a QR code of the new device  103  using an existing device  107  to interwork with the Cloud  105  of the preset manufacturer or distributor. Thus, the interworking information is transmitted to the existing device  107  and the new device  103  through the Cloud  105 , such that the existing device  107  and the new device  103  interwork with each other. 
         [0011]    According to the foregoing short-range communication technique, when a new device interworks with another device, a procedure for device registration has to be performed. That is, for Wi-Fi communication that allows an access of a device having a registered MAC address, a MAC address of the new device has to be registered in a Wi-Fi AP. In addition, a smart light bulb, a smart toothbrush, and so forth, which are capable of interworking with a smart device, has been developed and widely spread, and these devices do not include an input/output unit. As a result, in connection to the Wi-Fi AP, if authentication based on input of a password is required, the input of the password may not be easy to perform. Thus, an additional technique such as NFC is used, but mounting an NFC device used only for installation may increase unit cost. Moreover, in Bluetooth pairing, if there are many nearby devices participating in short-range communication, such as Bluetooth beacon, a smart light bulb, and the like, then many devices may be detected, making it difficult to identify a device for which pairing is to be attempted. 
         [0012]    When a QR code is scanned using an existing device for interworking with a new device, the existing device needs to scan a QR code for the new device and thus a device for scanning the QR code, such as a camera, is also needed. Moreover, Internet connection for identifying the QR code and interworking the QR code with an external interpreter is also needed. As a result, interworking with a device that is incapable of Internet connection or does not have a camera mounted thereon is difficult to achieve. In practice, many Internet of Things (IoT) devices have low-power local network connectivity which has no direct external Internet connectivity like Bluetooth. 
         [0013]    The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

       DETAILED DESCRIPTION 
       [0035]    Exemplary embodiments of the present disclosure will be described herein below with reference to the accompanying drawings. Although specific embodiments of the present disclosure are illustrated in the drawings and relevant detailed descriptions are provided, various changes can be made to the exemplary embodiments and various exemplary embodiments may be provided. Accordingly, the various exemplary embodiments of the present disclosure are not limited to the specific embodiments and should be construed as including all changes and/or equivalents or substitutes included in the ideas and technological scopes of the exemplary embodiments of the present disclosure. In the explanation of the drawings, similar reference numerals are used for similar components. 
         [0036]    The term “include” or “may include” used in the exemplary embodiments of the present disclosure indicates the presence of disclosed corresponding functions, operations, components, or the like, and does not limit additional one or more functions, operations, components, or the like. In addition, it should be understood that the term “include” or “has” used in the exemplary embodiments of the present disclosure is to indicate the presence of features, numbers, steps, operations, components, parts, or a combination thereof described in the specifications, and does not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or a combination thereof. 
         [0037]    The term “or” or “at least one of A or/and B” used in the various exemplary embodiments of the present disclosure includes any and all combinations of the associated listed items. For example, the term “A or B” or “at least one of A or/and B” may include (1) at least one A, (2) at least one B, or (3) both at least one A and at least one B. 
         [0038]    Although the terms such as “first” and “second” used in the various exemplary embodiments of the present disclosure may modify various components of the various exemplary embodiments, these terms do not limit the corresponding components. For example, these terms do not limit an order and/or importance of the corresponding components. These terms may be used for the purpose of distinguishing one component from another component. For example, a first user device and a second user device all indicate user devices or may indicate different user devices. For example, a first component may be named as a second component without departing from the right scope of the various exemplary embodiments of the present disclosure, and similarly, a second component may be named as a first component. 
         [0039]    When it is described that a component (such as a first component) is “operatively or communicatively coupled” to or “connected” to another component (such as a second component), the component can be directly connected to the other component or can be connected to the other component through a third component. However, when it is described that a component (such as a first component) is “directly connected” or “directly coupled” to another component (such as a second component), it means that there is no intermediate component (such as a third component) between the component and the other component. 
         [0040]    An expression “configured to (or set)” used in the present disclosure may be replaced with, for example, “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of” according to a situation. A term “configured to (or set)” does not always mean only “specifically designed to” by hardware. Alternatively, in some situation, an expression “apparatus configured to” may mean that the apparatus “can” operate together with another apparatus or component. For example, a phrase “a processor configured (or set) to perform A, B, and C” may be a generic-purpose processor (such as a CPU or an application processor) that can perform a corresponding operation by executing at least one software program stored at an exclusive processor (such as an embedded processor) for performing a corresponding operation or at a memory device. 
         [0041]    The terms used in the various exemplary embodiments of the present disclosure are for the purpose of describing particular exemplary embodiments only and are not intended to be limiting. As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. 
         [0042]    Unless defined otherwise, all terms used herein have the same meanings as generally understood by those having ordinary knowledge in the technical field to which the present disclosure pertains. Terms generally used and defined in dictionaries should be interpreted as having meanings consistent with meanings construed in the context of the related art, and should not be interpreted as having ideal or excessively formal meanings unless defined explicitly in this application. Depending on circumstances, terms defined in this document may not be interpreted as excluding embodiments of the present disclosure. 
         [0043]    Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. Like components are referred to as like reference numerals even through being illustrated in different drawings, and in the following description, only parts necessary for understanding of operations according to embodiments of the present disclosure will be described and other parts will not be described not to obscure the subject matter of the present disclosure. 
         [0044]      FIG. 2  is a block diagram illustrating a structure of an apparatus for providing a method for interworking between devices for short-range communication according to an embodiment of the present disclosure. 
         [0045]    Referring to  FIG. 2 , an apparatus for interworking between devices for short-range communication according to an embodiment of the present disclosure may include a new device  201 , a new device management unit  203 , an existing device management unit  205 , and an existing device  207 . Each unit may not be strictly separated and each unit may exist as a plurality of units. Each device may include an interface unit and a controller. 
         [0046]    The new device  201 , which newly joins short-range communication, may include information such as its Wireless Fidelity (Wi-Fi) Medium Access Control (MAC) address, Bluetooth MAC address, an International Mobile Station Equipment Identity (IMEI), which is an unique Identification (ID) of a device used in a cellular network, and so forth, and may further include a password, which is an authentication key for Wi-Fi connection. The new device  201  is capable of interworking with another device by using short-range communication such as Wi-Fi, Bluetooth, or the like, and may be set to be preferentially identified by or to preferentially interwork with a device designated by the new device management unit  203  or the existing device management unit  205  and the existing device  207 . Once a user obtains a new device and causes the new device to interwork with an account that interworks with the existing device management unit  205 , then the new device becomes an existing device from that time. 
         [0047]    The new device management unit  203  inputs information to the new device  201 . The information may include a password that is a password of a Wi-Fi device of a user having purchased and using the new device  201 . If the new device  201  operates as a Bluetooth beacon indicating a position, the information may include a name of a position that is to be broadcast by the new device  201 . The information may also include a name used for other devices to identify the new device. 
         [0048]    The new device management unit  203  obtains unique information of the new device  201 , such as a Wi-Fi MAC address, a Bluetooth MAC address, an IMEI value, and the like. The new device management unit  203  may also obtain information of the existing device  207  directly from the existing device  207  or through the existing device management unit  205 . 
         [0049]    The new device management unit  203  transmits the unique information of the new device  201  and information designated by the user for the new device  201  to the existing device  207  or the existing device management unit  205 . By using the information about the new device  201  transmitted from the new device management unit  203 , the existing device  207  or the existing device management unit  205  may input the information about the new device  201  required for interworking in advance in spite of absence of the new device  201 . 
         [0050]    The existing device management unit  205  manages the existing device  207  to interwork based on an account that is available in common, and to this end, transmits identical information to existing interworking devices at the same time or inputs particular information to some of the existing interworking devices. Account information for logging in the account may be stored in a physically separated or logically distinguished separate account server or in a memory of the existing device management unit  205 . The existing device  207  is a device the user has already owned, and may include any type of devices. 
         [0051]      FIGS. 3A and 3B  illustrate an interworking system according to a conventional art. 
         [0052]    Referring to  FIG. 3A , a smart device may interwork based on an account service called “Account”, and for devices interworking with each other through the account, a command and information may be input to the devices using another device interworking with the devices through the same account. For example, a device A interworking through an e-mail account of “Account”, abc@email.com, may install an application in a device B interworking through the same Google account or may cause various data to be received in the device B. In this case, the same Google account serves as the existing device management unit  205  of  FIG. 2 . Data delivery from the device A to the device B is referred to as “Push”.  FIG. 3B  illustrates an example of another conventional account service. 
         [0053]    The existing device management unit  205  of  FIG. 2  may store information of a device having interworked with the existing device  207  of  FIG. 2  and provide the information to another device interworking through the same account. If the device A and the device B may interwork, or are interoperable, with each other through the same account and the user causes a device C having interworked with the device A to interwork with the device B, then the existing device management unit  205  of  FIG. 2  causes the device B to recognize that the device C has a history of having interworked with the device A, and to this end, the existing device management unit  205  may provide information about the device C to the device B. 
         [0054]    As mentioned above, once the new device  201  interworks through an account of the existing device management unit  205  of  FIG. 2 , the new device  201  becomes an existing device, and the existing device  207  of  FIG. 2  may have existing interworking information in addition to a function of the new device  201  of  FIG. 2 . The existing interworking information may be information about another device with which the existing device has interworked, and the existing device  207  of  FIG. 2  provides the existing interworking information to the existing device management unit  205  of  FIG. 2 . If a device with no history of having interworked is detected, it may be determined using the existing interworking information whether the device has a history of having interworked with another device having the same account of the existing device management unit  205  of  FIG. 2 . 
         [0055]      FIG. 4  illustrates a method for inputting information about a new device to an existing device in advance according to an embodiment of the present disclosure. 
         [0056]    Referring to  FIG. 4 , in a process of purchasing the new device  201  capable of short-range communication in an Internet shopping mall, the user selects a payment method and inputs contact information and delivery address information of the user. At this time, the user selects, in  401 , a target device  207  with which the new device  201  is to interwork from among existing devices, previously receives, in  402 , information about the new device  201 , such as a Bluetooth MAC address, from the new device management unit  203 , and registers the information about the new device  201  in the target device (existing device)  207 . Thereafter, the new device  201  is delivered to the user in  403 , and the user performs, in  404 , Bluetooth pairing between the new device  201  and the existing device to which the user has transmitted the information about the new device  201 . The existing device having received the information about the new device  201  may display the new device  201  on top of a list of detected connectable devices other than the new device  201 . Additionally, the existing device may display where the new device  201  has been purchased, together with a name of the new device  201  in a pairing target list, allowing the user to easily identify the new device  201 . The new device may also be set to be automatically Bluetooth paired with the existing device. 
         [0057]      FIG. 5  illustrates a process of selecting a target device with which a new device is to interwork in a process of purchasing the new device according to an embodiment of the present disclosure. 
         [0058]    Referring to  FIG. 5 , an account in which a target device for interworking with a new device (e.g., the new device  201  of  FIG. 2 ) is registered is selected in popup window or window  501 , and information (an ID and a password of the account) necessary for logging in to the account is input in windows  502  and  503 , respectively. Finally, the target device for interworking with the new device is selected in windows  504  and  505 , respectively. 
         [0059]      FIGS. 6A and 6B  illustrate an example of displaying a Bluetooth pairing target list in an existing device in device interworking according to an embodiment of the present disclosure. 
         [0060]    Generally, as shown in  FIG. 6A , when Bluetooth pairing is performed, in an order of signal strengths of a signal-sensing device (an existing device according to the present disclosure) and a signal-sensed device (a new device according to the present disclosure), the devices are arranged, and a list of the arranged devices is displayed. If there are a plurality of devices having the same name, the devices having the same name are difficult to distinguish because only the names of the devices are displayed. However, according to an embodiment of the present disclosure, as shown in  FIG. 6B , information about a new device is registered in advance in an existing device and is displayed on top of a pairing target list, such that the new device may be easily identified even if other devices having the same device exist as in  601   FIG. 6B . 
         [0061]      FIG. 7  illustrates another example of displaying a Bluetooth pairing target list according to an embodiment of the present disclosure. 
         [0062]    As stated above, an existing device (e.g., the existing device  207  of  FIG. 2 ) provides information about another device with which an existing device has interworked to an existing device management unit, and if a new device having no history of having interworked is detected when pairing is performed, it is determined whether the new device has a history of having interworked with another device having the same account of the existing device management unit by using existing interworking information stored in the existing device management unit. If the new device has a history of having interworked, the new device is placed on top of the pairing target list as indicated by  701  of  FIG. 7 , and the existing interworking information is displayed together with a name of the new device, facilitating identification of the new device. 
         [0063]      FIGS. 8 and 9  show a procedure for pushing an MAC address of a new device to a Wi-Fi Access Point (AP) that is an existing device, according to an embodiment of the present disclosure. 
         [0064]    Referring to  FIG. 8 , if a Wi-Fi AP acts as the existing device  207  (of  FIG. 2 ) owned by the user is set to determine whether a Wi-Fi MAC address of a device connected to the Wi-Fi AP (the existing device  207 ) is included in a connection-allowed device list, the user selects, in  801 , the Wi-Fi AP (the existing device  207 ), which is a target device for interworking with the new device  201 , as described above in a process of purchasing the new device  201  which is to interwork with the Wi-Fi AP (the existing device  207 ), receives a Wi-Fi MAC address, which is unique information of the new device  201 , from the new device management unit  203 , and registers, in  802 , the Wi-Fi MAC address in the Wi-Fi AP (the existing device  207 ) in advance. If the new device  201  is delivered in  803 , the user causes the new device  201  and the Wi-Fi AP (the existing device  207 ) to interwork, in  804 , with each other using the Wi-Fi MAC address of the new device  201 , which has been registered in the Wi-Fi AP (the existing device  207 ) in advance. 
         [0065]    The user may also provide password information of the Wi-Fi AP of the user to a distributor (or a new device management unit) in a process of purchasing the new device, to request the distributor to previously input the password of the Wi-Fi AP of the user to the new device prior to delivery of the new device. 
         [0066]    That is, referring to  FIG. 9 , when selecting a target device for interworking with the new device  201  in a process of purchasing the new device  201 , the user sends a password of the target device, the Wi-Fi AP (the existing device  207 ), to the new device management unit  203  in  901 . The new device management unit  203  transmits unique information (that is, the Wi-Fi MAC address) of the new device  201  to the target device (the existing device  207 ) in  902 , inputs the password of the Wi-Fi AP received from the user to the new device  201  in  903 , and delivers the new device  201  to the user in  904 . Thereafter, the user causes the new device  201  and the target device (the existing device  207 ) to interwork with each other by using interworking information of the new device  201  input in advance to the target device (the existing device  207 ) and interworking information of the Wi-Fi AP input in advance to the new device  201 , in  905 . 
         [0067]    In another way to input the password of the Wi-Fi AP to a new device, when a distributor (or an online shopping mall) capable of serving as a new device management unit receives purchasing information of the new device from a purchaser (or user), the user is caused to input the password of the Wi-Fi AP and the input information may be delivered to the existing device management unit (e.g., the account server) or to the existing device through the existing device management unit. 
         [0068]      FIG. 10  illustrates a process of delivering a Wi-Fi MAC address of a smart light bulb, which is a new device, to a Wi-Fi AP, which is an existing device, according to an embodiment of the present disclosure. 
         [0069]    Referring to  FIG. 10 , the new device management unit  203 , the online shopping mall, delivers the Wi-Fi MAC address of the new device  201  to the existing device management unit  205  which then delivers the Wi-Fi MAC address of the new device  201  to the existing device, the Wi-Fi AP (the existing device  207 ). Then, the Wi-Fi AP (the existing device  207 ) adds the MAC address of the new device  201  delivered from the existing device management unit  205  to an access-allowed list in addition to MAC addresses of a cellular phone and a laptop computer, previously registered in the access-allowed list. 
         [0070]      FIGS. 11 and 12  illustrate a method for delivering unique information of a new device through an online distributor, which is a new device management unit, and an account server, which is an existing device management unit, according to an embodiment of the present disclosure. 
         [0071]    Referring to  FIG. 11 , when a user purchases the new device  201  in an online shopping mall, the user inputs account authentication information of an existing device in  1101  in a process of selecting a target device, which is the existing device  207  for interworking with the new device  201 . Then, the online shopping mall server, which is the new device management unit  203 , sends an authentication request to the account server, which is the existing device management unit  205 , in  1102 , and the account server  205  delivers a target device list registered with a corresponding account to the online shopping mall server  203  in  1103 . Then, the online shopping mall server  203  displays the target device list to the user who then selects a target device for interworking with the new device  201  from the displayed list in  1104 . Once the purchase of the new device  201  is completed, the online shopping mall server  203  delivers unique information of the new device  201  to the user-selected target device (the existing device  207 ) by using the interworking system as shown in  FIG. 3  in  1105 . If the new device  201  is delivered in  1106 , the new device  201  and the target device (the existing device  207 ) interwork with each other by using the information delivered in advance to the target device (the existing device  207 ) in  1107 . 
         [0072]    Referring to  FIG. 12 , when the user purchases the new device  201  in the online shopping mall, if the user inputs account authentication information of an existing device (e.g., the existing device  207 ) in a process of designating a target device, which is the existing device for interworking with the new device  201 , in  1201 , then the online shopping mall server, which is the new device management unit  203 , sends an authentication request to the account server, which is the existing device management unit  205 , in  1202 , and the account server  205  delivers a target device list registered in the account to the online shopping mall server  203  in  1203 . Then, the online shopping mall server  203  displays an interoperable target device list to the user, and the user selects a target device for interworking with the new device  201  from the displayed list in  1204 . The online shopping mall server  203  then delivers information about the user-selected target device to the account server  205  in  1205 , and the account server  205  then delivers unique information of the new device  201  to the selected target device in a push manner or the like in  1206 . Once the new device  201  is delivered in  1207 , the new device  201  and the target device (the existing device  207 ) interwork with each other by using the unique information of the new device  201  delivered in advance to the target device (the existing device  207 ) in  1208 . 
         [0073]      FIG. 13  illustrates a method for inputting position information to a new device in a purchasing process when the new device serves as a position marker according to an embodiment of the present disclosure. 
         [0074]    According to an embodiment of the present disclosure, when a new device serves as a position marker like a beacon or the like, position information to be marked by the new device and a name to be used for a management device to identify the new device may be previously selected in a purchasing process. That is, for a device having no input/output unit such as a smart light bulb, a smart toothbrush, or the like, the purchaser may input desired information to the new device through a new device management unit such as an online distributor or a device manufacturer. 
         [0075]    Referring to  FIG. 13 , the user selects an account in which a new device is to be registered like in  FIG. 5  in window  1301  in a process of purchasing the new device, and inputs log-in information of the account in windows  1302  and  1303 , respectively. After selecting a position to be marked by the new device in menus  1304  and  1305 , the user inputs a name for identifying the new device in menus  1306  and  1307 , respectively. 
         [0076]    Then, the new device management unit or the existing device management unit delivers information about the new device to the existing device through the procedure shown in  FIG. 11  or  12 , and after delivery of the new device, the new device and the existing device interwork with each other by using the information delivered in advance to the existing device. 
         [0077]    If the purchase of the new device is canceled, the information input to the new device management unit and the information delivered to the existing device management unit may be deleted and a detailed procedure for deleting the information does not have to be limited by the present disclosure. 
         [0078]      FIGS. 14 and 15  illustrate a method for arranging a list of interworking-target devices displayed in an existing device according to an embodiment of the present disclosure. 
         [0079]    Referring to  FIG. 14 , if a device having a history of having been Bluetooth-paired with an existing device interworking with a user account is detected from a pairing-possible (or pairable) target device list in a process of performing Bluetooth-pairing with another device interworking with the same user account, the device may be placed on top of the pairable target device list or information indicating that the device has a history of having been Bluetooth-paired with the existing device may be indicated in the list, together with a name of the device, to allow the user to easily identify the device as in  1401 . 
         [0080]    Referring to  FIG. 15 , when an interoperable device list is displayed, a device including user identification information, such as a user name or a user ID, in addition to names of detected devices is placed on top of the interoperable device list, allowing the user to easily identify the device in  1501 . 
         [0081]    In another way to apply a method for delivering information about a new device to an existing device according to an embodiment of the present disclosure, if the user purchases food, information about the food may be transmitted to an interworking-target device.  FIG. 16  illustrates such an embodiment of the present disclosure. 
         [0082]    Referring to  FIG. 16 , a distributor may previously store information about food for sale (nutrients, calories, and so forth) in a server of the distributor (e.g. the new device management unit  203 ), and if a user of the interworking-target device  207  requests purchase of one of products to be sold by the distributor (the new device management unit  203 ) interworking with an account server (e.g., the existing device management unit  205 ) of the target device  207  in  1601 , then the distributor (the new device management unit  203 ) provides the product to the purchaser (e.g. the target device  207 ), together with a receipt in  1602 , and delivers information about the product purchased by the purchaser to the account server (the existing device management unit  205 ) by using the purchaser&#39;s account information registered in advance in the server of the purchaser  203  in  1603 . The account server (the existing device management unit  205 ) having received product information of the purchaser delivers the product information to the interworking-target device  207  in a push manner in  1604 . Then, the purchaser may check, through the target device  207 , information such as nutrients, calories, and the like of the product, that is, food, purchased by the purchaser, and may use the information for health care, such as adjusting the amount of exercise or food intake or managing eating habits and body weight.
