PATENT DESCRIPTION
CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY 
       [0001]    The present application is related to and claims priority under 35 U.S.C. §119(a) to Korean Application Serial Nos. 10-2014-0072089 and 10-2014-0128539, which were filed in the Korean Intellectual Property Office on Jun. 13 2014 and Sep. 25, 2014, respectively, the entire content of which are hereby incorporated by reference. 
       TECHNICAL FIELD 
       [0002]    The present disclosure relates to a method and device for selecting a communication service to connect communication by user equipment in a communication system. 
       BACKGROUND 
       [0003]    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. 
         [0004]    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]    User equipment widely used in mobile communication markets generally has a flight mode implemented therein in order to readily interrupt all communication functions in a space where communication is not allowed, for example, in a space of an airplane while taking off or landing. The flight mode can be set by a user on the screen of a smart phone or through a specific physical button, etc. In the flight mode, the user equipment disables transmission and reception functions of all remote and short-range communication. Examples of the remote communication include commercial mobile communication systems, such as Global System for Mobile communication (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-A), and the like, and examples of the short-range communication include commercial mobile communication systems, such as Wireless Fidelity (WiFi), BLUETOOTH, and the like.  FIG. 1  illustrates an example of a method for setting a flight mode of a smart phone. User equipment  100  has a touch screen  105  on the front surface thereof, and a user inputs desired information by touching the touch screen. The touch screen displays a control screen for starting or stopping several functions, and the control screen includes a flight mode icon  110 . The user sets or disables a flight mode by touching the flight mode icon. In addition, the user also displays a screen for setting or disabling the flight mode by clicking a specific physical button implemented in the user equipment. Through various methods in addition to the above-described methods, the existing user equipment interrupts all communication. 
         [0006]    In the existing flight mode, the user equipment interrupts all the communication. However, the user may also want to interrupt only some communication rather than all the communication according to situations. For example, there is a case where an incoming call is unacceptable in everyday life. The user is not willing to receive an incoming call in a place that requires silence or when an undesired person makes a call to him or her. In the situation where the user cannot receive the incoming call, a ring tone or vibration for the incoming call is unnecessary. Accordingly, in the situation described above, a communication mode appropriate for the user&#39;s situation is required. 
         [0007]    A Universal Integrated Circuit Card (UICC) is a smart card inserted into a mobile communication terminal. The UICC stores private information of a mobile communication subscriber, authenticates the subscriber, and creates a traffic security key when the subscriber accesses a mobile communication network, thereby making it possible to stably use the mobile communication. 
         [0008]    The UICC is manufactured as a dedicated card for a specific mobile communication service provider according to the corresponding service provider&#39;s request and released with previously loaded authentication information, for example a Universal Subscriber Identity module (USIM) application, International Mobile Subscriber Identity (IMSI), a K value, and the like, for the network access of the corresponding service provider. Accordingly, the corresponding mobile communication service provider receives delivery of the manufactured UICC to provide it to the subscriber, and thereafter performs the management, such as installation, modification, deletion, and the like, of an application in the UICC using technologies such as Over The Air (OTA), etc. when necessary. The subscriber inserts the UICC into the mobile communication terminal of his or her own to use the network and application services of the corresponding mobile communication service provider, and when replacing the terminal, the subscriber moves the UICC from the existing terminal to a new terminal to use the authentication information, the mobile communication phone numbers, the personal telephone number list, and the like, which are stored in the UICC, in the new terminal as they are. 
         [0009]    The standardization group, called European Telecommunications Standards Institute (ETSI), defines the physical shape and the logical function of the UICC to maintain the international compatibility thereof. In terms of a form factor that defines a physical phenomenon, from the most widely used mini-SIM to a micro-SIM and a recently used nano-SIM, the size thereof becomes smaller. Although it contributes much to the compactness of a mobile communication terminal, it is expected that a UICC smaller in size than a recently established nano-SIM is difficult to standardize because a user is likely to lose it. Since the terminal requires a space for mounting a detachable slot due to a characteristic of the detachable UICC, further compactness is expected to be difficult. 
         [0010]    In order to solve such a problem, a demand for replacing the UICC by embedding a security module performing a similar function to the UICC in a mobile communication terminal when manufacturing the terminal is emerging. Accordingly, an embedded Universal Integrated Circuit Card (eUICC) structure, which is a UICC that cannot be detached, is proposed.

     DETAILED DESCRIPTION 
       [0075]      FIGS. 1 through 40 , discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communication device. Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Further, in the following description of the present disclosure, a detailed description of known functions and configurations incorporated herein will be omitted when it makes the subject matter of the present disclosure rather unclear. 
         [0076]    The present disclosure gives a description of technology for telephone call and message control. User Equipment (UE) includes a mobile communication terminal such as a cellular phone, a smart phone, and the like. 
         [0077]    Hereinafter, the present disclosure relates to a device and method for subscribing to a network in a wireless communication system. 
         [0078]    A messenger mode in the present disclosure is a mode for permitting only communication relating to a specific communication service. For various reasons, a user wants to interrupt only some communication. One of them is an incoming call. In an environment requiring silence, the user wants to interrupt only the incoming call causing noise and vibration. Or when the user does not want a spam call, the sender of which cannot be identified, noise or vibration is unnecessary for the user. In cases where the battery residual quantity of user equipment is small, a voice call communication service causes the battery to be rapidly discharged. Accordingly, it is necessary to permit only a text message or an application messenger communication service that restrictively uses the battery. Lastly, for a user&#39;s special purpose, for example, for communication between doctors in a hospital, a pager is still used, and user equipment also needs to provide a similar function. Accordingly, in consideration of the aforementioned user requirements, various embodiments of the present disclosure propose a technology for selectively interrupting only some functions. For example, user equipment, according to various embodiments of the present disclosure, interrupts a general incoming call communication service and permits only a text communication service, such as an SMS or MMS, and a messenger application messenger communication in a messenger mode. 
         [0079]    An existing text message like an SMS or MMS is permitted in a messenger mode. Although an incoming voice call is interrupted according to various embodiments of the present disclosure, an incoming voice call for a telephone number designated by a user is discriminatorily permitted. When the user designates a telephone number in advance, a call for the designated telephone number is permitted rather than being interrupted. Currently used user equipment utilizes a messenger communication service provided in an application form, in addition to an existing SMS or MMS text message. Many messenger communication services are introduced to markets, and a subscriber exchanges text messages with desired counterparts using an IP Internet network. CHATON SQUARE, SKYPE, KAKAOTALK, GTALK, and the like are examples of such messenger communication services. Communication is also permitted for all messenger applications or only for limited applications designated in advance by a user. The reason for permitting the communication only for the limited applications is to prevent a smart phone from consistently performing communication due to an unintended application. 
         [0080]    Since an incoming voice call is usually interrupted in a messenger mode, according to various embodiments of the present disclosure, it is possible to more flexibly set a communication system for supporting the messenger mode. For example, an LTE system identifies whether paging is received, at every Discontinuous Reception (DRX) period. As the DRX period is set to be longer, it is advantageous for saving the power consumption of user equipment. However, a voice call connection is delayed due to the DRX period set to be longer. When an incoming voice call is excluded, the power consumption of the user equipment can be significantly saved by setting the DRX period to be very long. In the case of a text message or a messenger communication service, a degree of delay is less sensitive, compared to in the case of a voice call. When a user sets a messenger mode, user equipment reports the messenger mode to a network and receives setting information according to that the messenger mode. 
         [0081]      FIG. 2  illustrates an example of displaying a messenger mode in a UE according to various embodiments of the present disclosure. 
         [0082]    A user sets or disables a messenger mode by simply clicking a control icon of the messenger mode in a UE. The user also displays the control icon  205  using a physical button. A UE manufacturer or the user displays the control icon  205  on a screen  200  by performing a series of touch screen or motion operations in advance. The control icon of the messenger mode is also displayed on the screen by pressing the physical button  230  of the UE for a predetermined period of time. The physical button is a multi-purpose button, such as the power button of the UE or a separate physical button. A control icon  225  of the messenger mode is displayed by pressing the physical button and control icons for other purposes, namely, an end icon ( 210 ), a restart icon ( 215 ), and a flight mode icon ( 220 ) are displayed at the same time. The end icon ( 210 ) is used to shut off the power of the UE, the restart icon ( 215 ) is used to restart the UE, and the flight mode icon ( 220 ) is used to interrupt the communication of the UE. In addition, through a separate physical button, the UE is switched to the messenger mode with one-click. 
         [0083]      FIG. 3  illustrates an example of a display method in the setting of a messenger mode for a UE according to various embodiments of the present disclosure. 
         [0084]    When a user switches the UE from a general communication mode to the messenger mode, it is displayed on the screen of the UE. This is to help the user consistently recognize the mode of the UE, thereby enabling the user to switch the messenger mode to the general communication mode again when it is necessary to receive an incoming voice call. The UE displays the status and a notification bar on the screen thereof. In various embodiments, the notification bar is located on the upper side of the screen  300 , and an indication ( 305 ) for notifying of the activation of the messenger mode is displayed on the notification bar. The indication is applied to both a general screen and a locked screen of the UE. At a predetermined location on the locked screen  310  of the UE, the activation of the messenger mode is also displayed to be large. When the user does not touch the screen of the UE for a predetermined period of time, the UE switches to the locked screen. The locked screen is for preventing the UE from performing an unintended operation through the user&#39;s unnecessary screen touch, and is displayed as a lock icon  315 . The UE switches the locked screen to a general screen through a click or motion on the icon. The user identifies a messenger mode indication  320  on the locked screen without having to switch to the general screen to recognize that an incoming voice call is being interrupted. Furthermore, when the user touches the messenger mode indication, a control icon for switching to the messenger mode is immediately displayed, thereby simplifying a mode switching procedure. In addition, a messenger-mode dedicated screen is also introduced. On the messenger mode screen, permitted messenger applications are also highlighted as indicated by reference numeral  330 , in addition to the display of the messenger mode activation state  325 . 
         [0085]    Embodiments of the present disclosure propose network control signaling for supporting the above-described messenger mode. When an incoming voice call, an SMS/MMS text message, and an application messenger are provided to a specific user in the messenger mode, signaling and operations performed by related network entities are different from each other. The present disclosure employs a new signaling message for supporting the messenger mode and a new network server for supporting the messenger mode. In the present disclosure, the new network server is referred to as a ‘messenger mode server.’ In addition, the messenger mode server decodes collected data and distinguishes between data of a messenger application to transfer only message data of a permitted application messenger to a specific UE. 
         [0086]      FIG. 4  illustrates an example of a control procedure for an incoming call according to various embodiments of the present disclosure. In  FIG. 4 , it is exemplified that a user of UE  2   415  attempts to make a voice call to a user of UE  1   400  according to various embodiments of the present disclosure. 
         [0087]    Referring to  FIG. 4 , in operation  420 , UE  1   400  switches to a messenger mode according to the user&#39;s specific intention or setting. The setting includes at least one of a setting for receiving Access Class Barring (ACB) information from a base station and automatically switching to a messenger mode when an access priority is low to reduce the consumption of a battery, and a setting for automatically switching to a messenger mode in the case of a specific place and time. 
         [0088]    In operation  425 , UE  1   400  transmits a messenger mode activation request message to a call session control server. The call session control server includes a Call Session Control Function (CSCF)  405  or a Mobility Management Entity (MME). The call session control server functions to handle a part relating to call and session processing and serves as a gateway for an incoming call. The request message is for informing the call session control server  405  that the UE switches to the messenger mode. In addition, the message includes a list of messenger applications that the user is using, and a list of uninterrupted telephone numbers. The message includes a list of messenger applications that are not used by the user, and a list of telephone numbers to interrupt. The request message is used for selectively providing a communication service to the UE. 
         [0089]    In operation  430 , the call session control server  405  stores the telephone number list included in the message. In operation  435 , the call session control server  405  transmits a messenger mode application message to a messenger mode server. The message includes the messenger application list. At the same time, in operation  440 , the call session control server  405  selectively provides new setting information to UE  1   400 . The new setting information includes setting information to which a very long DRX period is applied to maximize power consumption. 
         [0090]    When UE  2   415  attempts to make a voice call to UE  1   400  in operation  445 , information on the voice call attempt is reported to the call session control server  405 , and in operation  450 , the call session control server  405  determines whether to transmit a paging message for establishing the voice call to UE  1 . To this end, the call session control server compares a pre-stored telephone number list with the originating telephone number. If the originating telephone number exists in the list, the user of UE  1   400  has to be notified of the telephone number despite the messenger mode of UE  1 . In operation  455 , the call session control server  405  transmits a paging message to UE  1   400 . If not, the voice call has to be interrupted. 
         [0091]    In operation  460 , the call session control server  405  requests the messenger mode server  410  to process the interrupted call. The messenger mode server  410  functions to inform the user of UE  2   415  that the call has been interrupted due to the activation of the messenger mode in UE  1 . The messenger mode server  410  additionally provides a method of communicating with the user of UE  1   400 . To this end, in operation  465 , the messenger mode server  410  transmits, to UE  2   415 , an acknowledgement message including the messenger mode activation information of the counterpart and the messenger application list. 
         [0092]    In operation  470 , UE  2   415  automatically displays the activation or deactivation of the messenger mode of the counterpart and the messenger application list to the user. The user of UE  2  ( 415 ) creates a message using an SMS/MMS text message or the messenger application. 
         [0093]    In operation  475 , UE  2   415  transmits the message to UE  1   400 . If the created message is an SMS/MMS text message, the message is transmitted to the call session control server  405  and then provided to UE  1   400 . 
         [0094]    In cases where the user of UE  1   400  disables the messenger mode in operation  480 , UE  1   400  transmits a messenger mode deactivation message to the call session control server  405  in operation  485 . 
         [0095]    In operation  490 , the call session control server  405  deletes the telephone number list. In operation  495 , the call session control server  405  transmits the messenger mode deactivation message to the messenger mode server to inform that UE  1   400  has disabled the messenger mode. 
         [0096]      FIG. 5  illustrates an example of a method of displaying a message or a messenger after the interruption of an incoming call according to various embodiments of the present disclosure. When UE  2   415  identifies, in operation  470  of  FIG. 4 , that UE  1   400  of the user who wants to make a voice call is in the messenger mode, UE  2   415  immediately displays, on the screen thereof, a list of a text message application  500  and messenger applications  505 ,  510 ,  515 , and  520 , through which communication is possible, in order to reduce the operating procedure of the user of UE  2 . When the user of UE  2  selects one of the text message application and the messenger applications in the list, UE  2   415  switches to a dialogue window of the selected application and send messages to the user of UE  1   400 . In order to further reduce the user&#39;s operating procedure, UE  2   415  identifies the messenger mode of UE  1   400  and then immediately displays, on the screen thereof, a text message window or a dialogue window of a messenger application that has been designated in advance by the user. The dialogue window of the messenger application basically includes dialogue boxes  525  for displaying dialogue contents sent by the users of UE  1   400  and UE  2   415 , an input window  530  for receiving an input of a dialogue, and a send button  535  for instructing an input dialogue to be sent. 
         [0097]      FIG. 6  illustrates an example of a procedure of receiving an application message in a messenger mode according to various embodiments of the present disclosure. 
         [0098]    In  FIG. 6 , a specific communication service provider, for example, a messenger provider or an e-mail provider  615  attempts to provide application data to a user of UE  1   600 . 
         [0099]    In operation  620 , the user of UE  1   600  switches to a messenger mode according to his or her specific intention. In operation  625 , UE  1   600  transmits a messenger mode activation request message to a call session control server  605 . The call session control server  605  functions to handle a part relating to call and session processing and serves as a gateway for an incoming call. The message is for informing the call session control server  605  that the UE switches to the messenger mode. The message includes a list of messenger applications that the user is using, and a list of uninterrupted telephone numbers. The message information is used for selectively providing a communication service to the UE. In operation  630 , the call session control server  605  stores the telephone number list included in the message. 
         [0100]    In operation  635 , the call session control server  605  transmits a messenger mode application message to a messenger mode server. The message includes the messenger application list. At the same time, in operation  640 , the call session control server  605  selectively provides new setting information to UE  1   600 . The new setting information includes setting information to which a very long DRX period is applied to maximize power consumption. 
         [0101]    In operation  645 , the e-mail server  615  attempts to transmit application data to UE  1   600 . The data is an e-mail reception notification message, a received mail list, and the like. In operation  650 , the messenger mode server  610  having received the data identifies whether the data corresponds to application data included in the messenger application list. When the data corresponds to the data (message) of the messenger application, the messenger mode server  610  transmits the application data to UE  1   600  in operation  655 . When the data does not correspond to the messenger application data, the messenger mode server  610  sends an acknowledgement message for informing that the receiver&#39;s UE is in the messenger mode, to the e-mail server in operation  660 . In operation  665 , the messenger mode server stores the application data. This is to immediately transmit data to UE  1   600  when the messenger mode of UE  1   600  is disabled later. 
         [0102]    In operation  670 , the user of UE  1   600  disables the messenger mode. In operation  675 , UE  1   600  transmits a messenger mode deactivation message to the call session control server  605 . In operation  680 , the call session control server  605  deletes the telephone number list. In operation  685 , the call session control server  605  transmits a messenger mode release message to the messenger mode server, and in operation  690 , the messenger mode server transmits the application data stored therein to UE  1   600 . 
         [0103]      FIG. 7  illustrates an example of a procedure of receiving an SMS/MMS text message in a messenger mode according to various embodiments of the present disclosure. In  FIG. 7 , it is exemplified that a user of UE  2   715  attempts to send an SMS/MMS text message to a user of UE  1   700 . Since the SMS/MMS text message is a communication service that is allowable in a messenger mode, a signaling process is relatively simple, compared to the procedure for the incoming call control. In operation  720 , the user of UE  1   700  switches to a messenger mode according to his or her specific intention. In operation  725 , UE  1   700  transmits a messenger mode activation request message to a call session control server  705 . In operation  730 , the call session control server  705  stores a telephone number list included in the message. In operation  735 , the call session control server  705  transmits a messenger mode application message to a messenger mode server. In operation  740 , the call session control server selectively provides new DRX setting information to UE  1   700 . In operation  745 , UE  2   715  attempts to send an SMS/MMS text message to UE  1   700 . Since the SMS/MMS text message is a communication service that is allowable in the messenger mode, the call session control server is going to immediately forward the SMS/MMS text message to UE  1   700  without any special determination process in operation  750 . In operation  755 , the call session control server transmits the SMS/MMS text message to UE  1 . 
         [0104]      FIG. 8  illustrates an example of a control procedure for an incoming call according to various embodiments of the present disclosure. 
         [0105]    In operation  810 , a UE sets a messenger mode. Switching to the messenger mode is automatically performed in the case of a low access priority depending on a user setting or Access Class Barring (ACB) information received from a base station, in the case of a battery capacity less than a set value, or in the case of a specific place and time. 
         [0106]    In operation  820 , the UE transmits a messenger mode activation request message. The messenger mode activation request message includes information that an incoming call is interrupted, a non-messenger mode applied telephone number list, and a messenger application list, and the like. 
         [0107]    In operation  830 , a call session control server controls an incoming call. The call session control server checks the incoming call number and compares the same with the non-messenger mode applied telephone number list included in the messenger mode activation request message received from the UE. If the incoming call is not included in the non-messenger mode applied telephone number list, the call session control server interrupts the incoming call in operation  840 , and if the incoming call is included in the non-messenger mode applied telephone number list, the call session control server connects the incoming call in operation  850 . 
         [0108]      FIG. 9  illustrates an example of a control procedure for a messenger mode according to various embodiments of the present disclosure. 
         [0109]    In operation  910 , when a messenger mode is set, a UE displays a specific icon on the screen thereof and then transmits a messenger mode activation request message to a call session control server. The messenger mode activation request message includes information that an incoming call is interrupted, a non-messenger mode applied telephone number list, and a messenger application list, and the like. 
         [0110]    In operation  920 , the call session control server controls an incoming call. The call session control server checks the incoming call number and compares the same with the non-messenger mode applied telephone number list included in the messenger mode activation request message received from the UE. If the incoming call is not included in the non-messenger mode applied telephone number list, the call session control server interrupts the incoming call, and if the incoming call is included in the non-messenger mode applied telephone number list, the call session control server connects the incoming call. 
         [0111]    In operation  930 , the call session control server transmits a message according to the comparison result in operation  920 . The call session control server restricts the incoming call according to the incoming call interruption information, performs paging to the UE for an incoming call included in the non-messenger mode applied telephone number list, and forwards a call processing message to a messenger mode server for an incoming call not included in the non-messenger mode applied telephone number list. 
         [0112]      FIG. 10  illustrates an operation flow of a UE for messenger mode control according to various embodiments of the present disclosure. 
         [0113]    In operation  1010 , the UE sets a messenger mode. When the messenger mode is set, the UE displays a specific icon on the screen thereof. The setting includes at least one of a setting for receiving Access Class Barring (ACB) information from a base station and automatically switching to a messenger mode when an access priority is low to reduce the consumption of a battery, and a setting for automatically switching to a messenger mode in the case of a specific place and time. 
         [0114]    In operation  1020 , the UE transmits a messenger mode activation request message to a call session control server. The messenger mode activation request message includes information that an incoming call is interrupted, a non-messenger mode applied telephone number list, and a messenger application list, and the like. 
         [0115]      FIG. 11  illustrates an operation flow of a call session control server for messenger mode control according to various embodiments of the present disclosure. 
         [0116]    In operation  1110 , the call session control server receives a messenger mode activation request message from a UE. The messenger mode activation request message includes information that an incoming call is interrupted, a non-messenger mode applied telephone number list, and a messenger application list, and the like. 
         [0117]    In operation  1120 , the call session control server performs a control according to the messenger mode activation request message. The call session control server restricts an incoming call according to incoming call interruption information, performs paging to the UE for an incoming call included in the non-messenger mode applied telephone number list, and forwards a call processing message to a messenger mode server for an incoming call not included in the non-messenger mode applied telephone number list. 
         [0118]      FIG. 12  illustrates an operation flow of a server for messenger mode control according to various embodiments of the present disclosure. 
         [0119]    In operation  1210 , the server receives a messenger mode application message from a call session control server. The messenger mode application message includes information that a UE has been set to a messenger mode, and messenger application list information. 
         [0120]    In operation  1220 , the server receives application data from a communication service provider. The application data includes an e-mail reception notification message, a received e-mail list, and the like. 
         [0121]    In operation  1230 , the server compares the application data with the messenger application list. If the application list includes an application corresponding to the application data, the server transmits a message to the UE, and if the application list does not include an application corresponding to the application data, the server transmits an acknowledgement message to the communication service provider. 
         [0122]      FIG. 13  is a block diagram of a UE according to various embodiments of the present disclosure. 
         [0123]    Referring to  FIG. 13 , the UE includes a Radio Frequency (RF) processing unit  1310 , a baseband processing unit  1320 , a storage unit  1330 , a controller  1340 , and a display unit  1350 . 
         [0124]    The RF processing unit  1310  performs a function for transmitting and receiving a signal through a wireless channel, such as band conversion and amplification of a signal. The RF processing unit  1310  subjects a baseband signal provided from the baseband processing unit  1320  to up-conversion to an RF band signal and then transmits the converted signal through an antenna, and subjects an RF band signal received through the antenna to down-conversion to a baseband signal. For example, the RF processing unit  1310  includes a transmission filter, a reception filter, an amplifier, a mixer, an oscillator, a Digital-to-Analog Converter (DAC), an Analog-to-Digital Converter (ADC), and the like. Although only one antenna is illustrated in  FIG. 13 , the transmitting end includes a plurality of antennas. 
         [0125]    The baseband processing unit  1320  performs a conversion between a baseband signal and a bit string according to a physical layer standard of a system. For example, the baseband processing unit  1320 , when transmitting data, generates complex symbols by encoding and modulating a transmission bit string. In addition, the baseband processing unit  1320 , when receiving data, recovers a reception bit string through the demodulation and decoding of a baseband signal provided from the RF processing unit  1310 . For example, in the case of following the OFDM scheme, the baseband processing unit  1320 , when transmitting data, generates complex symbols by encoding and modulating a transmission bit string, maps the complex symbols with sub-carriers, and then configures Orthogonal Frequency Division Multiplexing (OFDM) symbols through an Inverse Fast Fourier Transform (IFFT) operation and Cyclic Prefix (CP) insertion. In addition, the baseband processing unit  1320 , when receiving data, divides a baseband signal provided from the RF processing unit  1310  in units of OFDM symbols, recovers signals mapped with sub-carriers through an FFT operation, and then recovers a reception bit string through demodulation and decoding. The baseband processing unit  1320  and the RF processing unit  1310  transmit and receive signals as described above. Accordingly, the baseband processing unit  1320  and the RF processing unit  1310  is referred to as a transmitter, a receiver, a transmitter/receiver, or a communication unit. 
         [0126]    The storage unit  1330  stores data such as a basic program, an application program, and setting information for the operation of a device for data transfer rate control. In particular, the storage unit  1330  stores information relating to a non-messenger mode applied telephone number list and a messenger application list. In addition, the storage unit  1330  provides data stored therein according to a request of the controller  1340 . 
         [0127]    The controller  1340  controls overall operations of a device for managing a messenger mode. For example, the controller  1340  accesses a base station by transmitting a signal through the baseband processing unit  1320  and the RF processing unit  1310 . The controller controls the device for managing a messenger mode to perform the procedures illustrated in  FIGS. 2 to 9 . According to various embodiments of the present disclosure, the operation of the controller  1340  is as follows. 
         [0128]    The controller  1340  controls the setting of a messenger mode. The controller receives ACB information from a base station and set the mode of a UE to the messenger mode when an access priority is determined to be low. In addition, the controller identifies the battery capacity of the UE and set the mode of the UE to the messenger mode when the battery residual quantity is less than a preset value. The messenger mode is characterized by receiving only exceptionally set calls and interrupting the remaining calls for voice calls, and receiving only application messages or SMS/MMS messages. 
         [0129]    The display unit  1350  receives information from the controller and displays the same on the screen of hardware. For example, the display unit  1350  displays icons and application execution screens on the screen thereof on the basis of communication service information from the controller. 
         [0130]      FIG. 14  illustrates a server according to various embodiments of the present disclosure. 
         [0131]    Referring to  FIG. 14 , the server includes a communication unit  1410 , a storage unit  1420 , and a controller  1430 . 
         [0132]    The communication unit  1410  performs a function for transmitting and receiving a signal through a wireless channel, such as band conversion and amplification of a signal. The communication unit  1410  performs a conversion between a baseband signal and a bit string according to a physical layer standard of a system. Accordingly, the communication unit  1410  is referred to as a transmitter, a receiver, or a transmitter/receiver. 
         [0133]    The storage unit  1420  stores data such as a basic program, an application program, and setting information for the operation of a device for controlling a call session control server. In particular, the storage unit  1420  stores information on a messenger mode activation request message including information that an incoming call is interrupted, a non-messenger mode applied telephone number list, a messenger application list, and the like. In addition, the storage unit  1420  provides data stored therein according to a request of the controller  1430 . 
         [0134]    The controller  1430  controls overall operations of a device for managing a messenger mode. For example, the controller  1430  transmits a signal through the communication unit  1410 . The controller controls the device for controlling the call session control server to perform the procedures illustrated in  FIGS. 8 ,  9 , and  11 . 
         [0135]    The controller  1430  performs a control according to a messenger mode activation request message. The controller restricts an incoming call according to incoming call interruption information, performs paging to the UE for an incoming call included in the non-message mode applied telephone number list, and forwards a call processing message to a messenger mode server for an incoming call not included in the non-messenger mode applied telephone number list. 
         [0136]    The messenger mode is also used when the UE accesses a mobile communication network using an embedded Universal Integrated Circuit Card (eUICC). 
         [0137]      FIG. 15  illustrates an example of a wireless communication method between a UE and a communication service provider according to various embodiments of the present disclosure. 
         [0138]    Referring to  FIG. 15 ,  FIG. 15  ( a ) illustrates a case in which a user connects to a wireless communication network through a Universal Integrated Circuit Card (UICC). In  FIG. 15  ( a ), a UE  1510  communicates with a mobile communication service provider  1530  using a UICC  1520 . The UICC  1520  provides a service only for a specific mobile communication service provider since only authentication information for the network access of a one specific mobile communication service provider is included in each UICC. Therefore, the user accesses the network of the specific mobile communication service provider  1530  according to the UICC  1520  by inserting the UICC  1520  into the UE  1510 . 
         [0139]      FIG. 15B  illustrates a case in which a user connects to a wireless communication network through an embedded Universal Integrated Circuit Card (eUICC). In  FIG. 15  ( b ), a UE  1550  communicates with a mobile communication service provider  1570  using an eUICC  1560 . Unlike the UICC  1520  providing only a service for a predetermined specific mobile communication service provider, the eUICC  1560  allows the user to determine a specific mobile communication service provider among a plurality of mobile communication service providers to use a service that the corresponding communication service provider provides. When the user requests the specific mobile communication service provider  1570  to provide a service, using the UE including the eUICC  1560  embedded therein, the specific mobile communication service provider  1570  requests a profile providing server  1580  to download a profile, and the profile providing server  1580  encrypts the profile of the specific mobile communication service provider  1570  and then transfers the same to a profile managing server  1590 . When the profile managing server  1590  transfers the encrypted profile to the eUICC using the Over The Air (OTA) technology, the UE  1550  downloads and installs the received encrypted profile to access the network of the specific mobile communication service provider  1570 . 
         [0140]    The eUICC  1560  has an eUICC Identifier (eUICCID), a secret key, and an OTA key recorded therein and includes a plurality of storage spaces. The eUICCID is unique identification information of the eUICC  1560  that is transferred to a network provider when the user subscribes to the network provider. The secret key is an encryption key for the eUICC  1560 , which is used when a profile is encrypted and transferred to the eUICC  1560 . The OTA key is a key for the management of the eUICC  1560 , which is used for secondary encrypting of the eUICC profile. 
         [0141]    Each of the storage spaces is used for storing a profile, and the profile store information included in the UICC. For example, the profile includes Universal Integrated Circuit Card Identifier (UICCID) information, Universal Subscriber Identity Module (USIM) information, banking information, and the like. A profile generated from a specific network provider is stored and activated in any one of the storage spaces so that the eUICC functions as an eUICC of the network provider. 
         [0142]    Through the wireless communication network access using the eUICC, the user selects a specific mobile communication service provider among a plurality of mobile communication service providers to receive a wireless communication network service. In order to select the specific mobile communication service provider, the user accesses an intermediary server that sells a mobile communication network service. 
         [0143]      FIG. 16  illustrates an example of providing a service for the selection of a service product that provides a wireless communication network service according to various embodiments of the present disclosure. 
         [0144]      FIG. 16  illustrates an example  1610  of the screen display in cases where a user accesses an intermediary server that sells a mobile communication network service. The user accesses the intermediary server to identify service contents that a mobile communication service provider provides. The service contents include information on a mobile communication service provider  1620 , a payment system  1630 , provided service contents  1640 , and the like. The information on the payment system  1630  and the provided service contents  1640  includes information on payment in advance or later, information on a monthly service fee, information on a lump sum payment, information on pre-tax or after-tax, information on the amount of calls to be available, information on the amount of data to be available, information on a method of deducting the amount of calls to be available, information on a method of deducting the amount of data to be available, and information on an additional service. 
         [0145]    The information is displayed as text or an image. The location and the sequence in which the information is displayed are determined by a service provider of a server that plays an intermediary role in the trade of communication service products. 
         [0146]      FIG. 17  illustrates an example of a communication service opening process of a UE using an eUICC according to various embodiments of the present disclosure. 
         [0147]    Referring to  FIG. 17 , the communication service opening process of a UE using an eUICC is performed through communication among a UE  1701 , an intermediary server  1703 , a mobile communication service provider  1705 , a profile providing server  1707 , and a profile managing server  1709 . 
         [0148]    In operation  1710 , the UE  1701  accesses the intermediary server  1703  that plays an intermediary role in the trade of profiles between the mobile communication service provider  1705  and the UE  1701  of a user. Although only one intermediary server  1703  is illustrated in the drawing, a plurality of intermediary servers is provided, in which case the UE  1701  accesses a specific intermediary server among the plurality of intermediary servers. In cases where the plurality of intermediary servers are provided, the UE  1701  accesses an intermediary server set as a default or accesses other intermediary servers according to sites. The access to the intermediary server  1703  is made manually by a user selection or automatically by the UE. The user accesses the intermediary server  1703  by executing a specific application of the UE  1701  or manually accesses the intermediary server  1703  through a selection on a specific screen of a specific application. In addition, the UE  1701  automatically accesses the intermediary server  1703  in cases where a profile through which a communication service is available at present does not exist or in cases where a communication service is available only through roaming and there is no profile of a local network user. The UE  1701  accesses the intermediary server  1703  by providing the user&#39;s Identification (ID) and password, or by providing the user&#39;s telephone number, and transmits eUICC identifier information for distinguishing the eUICC included in the UE to the intermediary server  1703 . 
         [0149]    In operation  1720 , the intermediary server  1703  provides product information to the UE  1701 . When the UE  1701  accesses the intermediary server  1703 , the intermediary server  1703  transmits information for subscribing to or purchasing a communication product to the UE  1701 . The information is displayed as text or an image. The information include information on the mobile communication service provider  1705 , a payment system, provided service contents, and the like, and the location and the sequence in which the information is displayed is determined by a service provider of the intermediary server  1703 . The UE  1701  displays the information received from the intermediary server  1703 . The UE  1701  displays the information as illustrated in  FIG. 2  or displays the symbol or the communication company name of the mobile communication service provider  1705 . When the user selects the symbol or the name of the corresponding mobile communication service provider, the UE  1701  also displays available payment systems. In addition, the UE  1701  displays the fact that the network access information of the mobile communication service provider  1705  is downloaded through a network. The UE  1701  displays a screen through which the user determines a selection of a communication product of a specific mobile communication service provider. For example, the UE  1701  displays a screen for selecting a communication product payment method and displays a screen for inputting credit card or bank account information as the payment method. In certain embodiments, the UE  1701  may also omit the payment method selecting process without providing a separate screen. 
         [0150]    In operation  1730 , the UE  1701  transmits product purchase information to the intermediary server  1703 . The product purchase information includes a product identifier, an eUICC identifier, and payment information. The product identifier includes information for distinguishing the selection of a specific mobile communication company and a specific payment system. The payment information includes credit card information or bank account information or includes information for notifying of the use of credit card or bank account information stored in the intermediary server  1703 . 
         [0151]    In operation  1740 , the intermediary server  1703 , after receiving the product purchase request information from the UE  1701 , transmits product purchase processing request information to the mobile communication service provider  1705  according to the product identifier. For example, when information on a specific mobile communication service provider is included in the product identifier, the intermediary server  1703  transmits the product purchase processing request information to the corresponding specific mobile communication service provider  1705 . In addition, the product identifier includes information on a payment system product, profile distinction information, and arbitrary information supported by the mobile communication service provider  1705 . When the product identifier includes the profile distinction information, the profile identifier is an Integrated Circuit Card Identifier (ICCID) value. When the intermediary server  1703  transmits the eUICC identifier information, received from the UE  1701 , to the mobile communication service provider  1705 , the mobile communication service provider  1705  identifies an eUICC where a communication profile is to be installed. 
         [0152]    In operation  1745 , the mobile communication service provider  1705  performs approval for the product purchase processing request information received from the intermediary server  1703 . After receiving the product purchase processing request from the intermediary server  1703 , the mobile communication service provider  1705  updates information for providing a communication service to the UE  1701 . For example, the mobile communication service provider  1705  updates an activation field corresponding to Integrated Mobile Subscription Identifier (IMSI) information mapped with the profile identifier to an authentication server. In addition, the mobile communication service provider  1705  performs mapping onto the profile identifier using the product identifier received from the intermediary server  1703 .

         [0154]    In operation  1760 , the profile providing server  1707  requests the profile managing server  1709  to download a profile. Although the term ‘profile providing server’ is used in certain embodiments of the present disclosure, the profile providing server  1707  is Subscription Management Data Preparation (SM-DP), a profile provider, a profile provisioner, a profile provisioning credentials holder, or the like. The profile providing server  1707  preserves profile information including subscriber information installed in the eUICC and creates a profile in the fond that can be installed in the eUICC. When receiving the profile download request from the mobile communication service provider  1705 , the profile providing server  1707  creates a profile to allow the eUICC corresponding to the eUICC identifier to download the profile, using the received eUICC identifier and the profile identifier. The profile providing server  1707  transmits a download request message to the profile managing server  1709  to allow the UE  1701  to download the created profile. The profile is transmitted through the download request message or another form of message. The transmission is performed by transmitting a message once or by exchanging messages several times. 
         [0155]    In operation  1770 , the profile managing server  1709  transmits the profile to the UE  1701 . Although the term ‘profile managing server’ is used in the embodiment of the present disclosure, the profile managing server  1709  is Subscription Manager Secure Routing (SM-SR), a profile manager, a profile management credentials holder, or the like. The profile managing server  1709  remotely transmits the profile to the UE corresponding to the eUICC, using the eUICC identifier included in the profile download request message received from the profile providing server  1707 . The transmission is performed through message transmission/reception using a Short Message Service (SMS), message transmission/reception using IP communication of a mobile communication network, or message transmission/reception using IP communication through short-range communication technology, such as Wireless Fidelity (WiFi), Bluetooth, Near Field Communication (NFC), or the like, or Universal Serial Bus (USB) connection with a UE having a communication function. In the process of transmitting the profile, the profile managing server  1709  transmits the profile or the profile data received from the profile providing server  1707  to the UE  1701 , and transmits a processing result received from the UE  1701  to the profile providing server  1707 . If the profile managing server  1709  fails to receive the processing result from the UE  1701 , the profile managing server  1709  transmits the corresponding profile or profile data again. The profile managing server  1709  stores all or some data of the profile download request message received from the profile providing server  1707  without transmitting the same, and when receiving a download request from the UE  1701 , transmits the profile or profile data to the UE  1701 . 
         [0156]    The UE  1701  downloads the profile from the profile managing server  1709 , activate the downloaded profile and accesses the corresponding mobile communication company to use a communication service. The activation of the profile is selected by the user or is automatically selected using information included in a message received from the profile managing server  1709 . When the profile is completely downloaded, the UE  1701  accesses the profile managing server  1709  or the intermediary server  1703  to transmit information as to whether the download is completed. The information as to whether the download is completed includes the eUICC identifier and the profile ID.

In the process of transmitting the profile, the profile managing server  2509  transmits the profile or the profile data received from the profile providing server  2507  to the UE  2501 , and transmits a processing result received from the UE  2501  to the profile providing server  2507 . If the profile managing server  2509  fails to receive the processing result from the UE  2501 , the profile managing server  2509  transmits the corresponding profile or profile data again. The profile managing server  2509  stores all or some data of the profile download request message received from the profile providing server  2507  without transmitting the same, and when receiving a download request from the UE  2501 , transmits the profile or profile data to the UE  2501 . 
         [0245]    The UE  2501  downloads the profile from the profile managing server  2509 , activate the downloaded profile, and access the corresponding mobile communication company to use a communication service. The activation of the profile is selected by the user or is automatically selected using information included in a message received from the profile managing server  2509 . When the profile is completely downloaded, the UE  2501  accesses the profile managing server  2509  or the intermediary server  2503  to transmit information as to whether the download is completed. The information as to whether the download is completed includes the eUICC identifier and the profile ID.

         [0258]    The intermediary server receives product purchase request information from the UE and then transmits product purchase processing request information to a mobile communication service provider according to the product identifier. For example, if information on a specific mobile communication service provider is included in the product identifier, the intermediary server transmits the product purchase processing request information to the corresponding specific mobile communication service provider. In addition, the product identifier includes information on a payment system product, profile distinction information, and arbitrary information supported by the mobile communication service provider. If the product identifier includes the profile distinction information, the profile identifier is an ICCID value. When the intermediary server transmits eUICC identifier information received from the UE to the mobile communication service provider, the mobile communication service provider identifies an eUICC where a communication profile is to be installed. 
         [0259]      FIG. 28  illustrates an example of an operation flow of a profile providing server for opening a communication service of a UE using an eUICC according to various embodiments of the present disclosure. 
         [0260]    In operation  2810 , the profile providing server creates a profile. The profile providing server creates a profile for an eUICC when receiving a profile download request or in cases where a determination is made in advance.

         [0333]    The baseband processing unit  3720  performs a conversion between a baseband signal and a bit string according to a physical layer standard of a system. For example, the baseband processing unit  3720 , when transmitting data, generates complex symbols by encoding and modulating a transmission bit string. In addition, the baseband processing unit  3720 , when receiving data, recovers a reception bit string through the demodulation and decoding of a baseband signal provided from the RF processing unit  3710 . For example, in the case of following the OFDM scheme, the baseband processing unit  3720 , when transmitting data, generates complex symbols by encoding and modulating a transmission bit string, maps the complex symbols with sub-carriers, and then configures Orthogonal Frequency Division Multiplexing (OFDM) symbols through an Inverse Fast Fourier Transform (IFFT) operation and Cyclic Prefix (CP) insertion. In addition, the baseband processing unit  3720 , when receiving data, divides a baseband signal provided from the RF processing unit  3710  in units of OFDM symbols, recovers signals mapped with sub-carriers through an FFT operation, and then recovers a reception bit string through demodulation and decoding.
