Title: Electronic device for selecting network

Description:
This application is the U.S. national phase of International Application No. PCT/KR2017/014257 filed 6 Dec. 2017, which designated the U.S. and claims priority to KR 10-2016-0173605 filed 19 Dec. 2016, the entire contents of each of which are hereby incorporated by reference. 
     TECHNICAL FIELD 
     The disclosure relates to technologies for selecting a network. 
     BACKGROUND ART 
     With the development of mobile communication technology, electronic devices, each of which has an antenna, for example, smartphones and wearable devices, have come into wide use. Such an electronic device may be connected with a Wi-Fi network, an LTE network, or the like via the antenna to transmit and receive messages, photos, videos, music files, games, or the like. 
     Respective networks available to the electronic device may have different features. For example, the LTE network provided to limited subscriber ensures high security and stable communication environments instead of paying fees for use thereof. On the other hand, the Wi-Fi network available for free provides relatively low security and variable communication environments. 
     Because there are advantages and disadvantages in respective networks available to an electronic device, the electronic device needs to select the network depending on a situation of its user. For example, to prevent fees from occurring when the user receives a large file, the electronic device needs to be connected with a Wi-Fi network. Unlike the above-mentioned example, to provide a stable communication environment to the user when the user plays a video, the electronic device needs to be connected with an LTE network. 
     However, because the electronic device is unable to determine a situation of the user and select a network suitable for the situation of the user, the user directly should select a network to be connected with the electronic device. Because the user directly should select the network to be connected with the electronic device depending to the situation, he or she feels uncomfortable. 
     SUMMARY 
     Various embodiments disclosed in the disclosure are to provide an electronic device for addressing the above-mentioned problems and issues raised in the disclosure. 
     In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device may include a communication circuitry, a processor electrically connected with the communication circuitry, and a memory electrically connected with the processor. The memory may store instructions, when executed, causing the processor to connect the electronic device and a first network using the communication circuitry, determine a first user context among user contexts which are data associated with an operation state of the electronic device, and maintain a connection with the first network or switch from the first network to a second network different from the first network based on whether communication quality of the first network meets first communication quality corresponding to the determined first user context. 
     In accordance with another aspect of the disclosure, an electronic device is provided. The electronic device may include a communication circuitry, a processor electrically connected with the communication circuitry, and a memory electrically connected with the processor.

     DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS 
     Hereinafter, various embodiments of the disclosure may be described with reference to accompanying drawings. Accordingly, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the disclosure. With regard to description of drawings, similar components may be marked by similar reference numerals. 
     In the disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., components such as numeric values, functions, operations, or parts) but do not exclude presence of additional features. 
     In the disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included. 
     The terms, such as “first”, “second”, and the like used in the disclosure may be used to refer to various components regardless of the order and/or the priority and to distinguish the relevant components from other components, but do not limit the components. For example, “a first user device” and “a second user device” indicate different user devices regardless of the order or priority. For example, without departing the scope of the disclosure, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component. 
     It will be understood that when an component (e.g., a first component) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another component (e.g., a second component), it may be directly coupled with/to or connected to the other component or an intervening component (e.g., a third component) may be present. In contrast, when an component (e.g., a first component) is referred to as being “directly coupled with/to” or “directly connected to” another component (e.g., a second component), it should be understood that there are no intervening component (e.g., a third component). 
     According to the situation, the expression “configured to” used in the disclosure may be used as, for example, the expression “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” must not mean only “specifically designed to” in hardware. Instead, the expression “a device configured to” may mean that the device is “capable of” operating together with another device or other parts. For example, a “processor configured to (or set to) perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which performs corresponding operations by executing one or more software programs which are stored in a memory device. 
     Terms used in the disclosure are used to describe specified embodiments and are not intended to limit the scope of the disclosure. The terms of a singular form may include plural forms unless otherwise specified. All the terms used herein, which include technical or scientific terms, may have the same meaning that is generally understood by a person skilled in the art. It will be further understood that terms, which are defined in a dictionary and commonly used, should also be interpreted as is customary in the relevant related art and not in an idealized or overly formal unless expressly so defined in various embodiments of the disclosure. In some cases, even if terms are terms which are defined in the disclosure, they may not be interpreted to exclude embodiments of the disclosure.

       FIG. 1  illustrates an electronic device in a network environment system, according to various embodiments. 
     Referring to  FIG. 1 , according to various embodiments, an electronic device  101 , a first electronic device  102 , a second electronic device  104 , or a server  106  may be connected each other over a network  162  or a short range communication  164 . The electronic device  101  may include a bus  110 , a processor  120 , a memory  130 , an input/output interface  150 , a display  160 , and a communication interface  170 . According to an embodiment, the electronic device  101  may not include at least one of the above-described components or may further include other component(s). 
     For example, the bus  110  may interconnect the above-described components  110  to  170  and may include a circuit for conveying communications (e.g., a control message and/or data) among the above-described components. 
     The processor  120  may include one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP). For example, the processor  120  may perform an arithmetic operation or data processing associated with control and/or communication of at least other components of the electronic device  101 . 
     The memory  130  may include a volatile and/or nonvolatile memory. For example, the memory  130  may store commands or data associated with at least one other component(s) of the electronic device  101 . According to an embodiment, the memory  130  may store software and/or a program  140 . The program  140  may include, for example, a kernel  141 , a middleware  143 , an application programming interface (API)  145 , and/or an application program (or “an application”)  147 . At least a part of the kernel  141 , the middleware  143 , or the API  145  may be referred to as an “operating system (OS)”. 
     For example, the kernel  141  may control or manage system resources (e.g., the bus  110 , the processor  120 , the memory  130 , and the like) that are used to execute operations or functions of other programs (e.g., the middleware  143 , the API  145 , and the application program  147 ). Furthermore, the kernel  141  may provide an interface that allows the middleware  143 , the API  145 , or the application program  147  to access discrete components of the electronic device  101  so as to control or manage system resources. 
     The middleware  143  may perform, for example, a mediation role such that the API  145  or the application program  147  communicates with the kernel  141  to exchange data. 
     Furthermore, the middleware  143  may process task requests received from the application program  147  according to a priority. For example, the middleware  143  may assign the priority, which makes it possible to use a system resource (e.g., the bus  110 , the processor  120 , the memory  130 , or the like) of the electronic device  101 , to at least one of the application program  147 . For example, the middleware  143  may process the one or more task requests according to the priority assigned to the at least one, which makes it possible to perform scheduling or load balancing on the one or more task requests. 
     The API  145  may be, for example, an interface through which the application program  147  controls a function provided by the kernel  141  or the middleware  143 , and may include, for example, at least one interface or function (e.g., an instruction) for a file control, a window control, image processing, a character control, or the like. 
     The input/output interface  150  may play a role, for example, of an interface which transmits a command or data input from a user or another external device, to other component(s) of the electronic device  101 . Furthermore, the input/output interface  150  may output a command or data, received from other component(s) of the electronic device  101 , to a user or another external device. 
     The display  160  may include, for example, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display  160  may display, for example, various contents (e.g., a text, an image, a video, an icon, a symbol, and the like) to a user. The display  160  may include a touch screen and may receive, for example, a touch, gesture, proximity, or hovering input using an electronic pen or a part of a user&#39;s body. 
     For example, the communication interface  170  may establish communication between the electronic device  101  and an external device (e.g., the first electronic device  102 , the second electronic device  104 , or the server  106 ). For example, the communication interface  170  may be connected to the network  162  over wireless communication or wired communication to communicate with the external device (e.g., the second electronic device  104  or the server  106 ). 
     The wireless communication may use at least one of, for example, long-term evolution (LTE), LTE Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), Wireless Broadband (WiBro), Global System for Mobile Communications (GSM), or the like, as cellular communication protocol. Furthermore, the wireless communication may include, for example, the short range communication  164 . The short range communication  164  may include at least one of wireless fidelity (Wi-Fi), Bluetooth, near field communication (NFC), magnetic stripe transmission (MST), a global navigation satellite system (GNSS), or the like. 
     The MST may generate a pulse in response to transmission data using an electromagnetic signal, and the pulse may generate a magnetic field signal. The electronic device  101  may transfer the magnetic field signal to point of sale (POS), and the POS may detect the magnetic field signal using a MST reader. The POS may recover the data by converting the detected magnetic field signal to an electrical signal. 
     The GNSS may include at least one of, for example, a global positioning system (GPS), a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter referred to as “Beidou”), or an European global satellite-based navigation system (hereinafter referred to as “Galileo”) based on an available region, a bandwidth, or the like. Hereinafter, in the disclosure, “GPS” and “GNSS” may be interchangeably used. The wired communication may include at least one of, for example, a universal serial bus (USB), a high definition multimedia interface (HDMI), a recommended standard-232 (RS-232), a plain old telephone service (POTS), or the like. The network  162  may include at least one of telecommunications networks, for example, a computer network (e.g., LAN or WAN), an Internet, or a telephone network. 
     Each of the first and second electronic devices  102  and  104  may be a device of which the type is different from or the same as that of the electronic device  101 . According to an embodiment, the server  106  may include a group of one or more servers. According to various embodiments, all or a portion of operations that the electronic device  101  will perform may be executed by another or plural electronic devices (e.g., the first electronic device  102 , the second electronic device  104  or the server  106 ). According to an embodiment, in the case where the electronic device  101  executes any function or service automatically or in response to a request, the electronic device  101  may not perform the function or the service internally, but, alternatively additionally, it may request at least a portion of a function associated with the electronic device  101  from another device (e.g., the electronic device  102  or  104  or the server  106 ). The other electronic device may execute the requested function or additional function and may transmit the execution result to the electronic device  101 . The electronic device  101  may provide the requested function or service using the received result or may additionally process the received result to provide the requested function or service. To this end, for example, cloud computing, distributed computing, or client-server computing may be used. 
       FIG. 2  illustrates a drawing for classifying a user context according to an embodiment. In the disclosure, details described in  FIG. 1  may also be applied to components having the same denotations as those of an electronic device  101  described in  FIG. 1 . 
     Referring to  FIG. 2 , a memory  130  may store a user context and/or at least one application. The user context may be data associated with an operation state of the electronic device  101 . For example, the user context may vary with an application executed in the electronic device  101 , network preference of a user, or the like. Furthermore, the user context may vary with an ON/OFF state of a display, location information of the electronic device  101 , or the like. 
     As an embodiment, the user context may vary with an ON/OFF state of the display  160 . For example, when the display  160  is in an ON state and when the display  160  is in an OFF state, a user context corresponding to each state may vary. As an embodiment, the user context may vary with a location of the electronic device  101 . For example, when the electronic device is located in a house of the user and when the electronic device is located in a company of the user, a user context according to each location may vary. 
     As an embodiment, the electronic device  101  may determine a user context based on the ON/OFF state of the display  160  and/or a type of an application executed in the electronic device  101 . For example, when the display  160  is ON and when a message application is executed, the electronic device  101  may determine the user context as a messaging context. When the display  160  is OFF and when an audio application is executed, the electronic device  101  may determine the user context as an audio context. 
     According to an embodiment of the disclosure, the electronic device  101  may divide the user context into at least one level (hereinafter referred to as “class”). That is, the class may be a grade of dividing the user context depending on a predetermined criterion. 
     According to an embodiment, the electronic device  101  may divide the user context into at least one class on the basis of network preference. For example, in  FIG. 2 , as a class number is smaller (e.g., as the class number is closer to C 1 ), there may be a higher probability that the electronic device  101  will be connected with LTE. As the class number is larger (e.g., as the class number is closer to C 9 ), there may be a higher probability that the electronic device  101  will be connected with Wi-Fi. For example, a context corresponding to a situation (data limit exhausted) where all of data usage is exhausted may correspond to C 9 . In this case, no matter how bad signal quality of LTE data is, the electronic device  101  may perform only a Wi-Fi connection. On the other hand, when a video is played with the display turned ON, the user context may correspond to C 1 . When a state of Wi-Fi does not reach a significant level, the electronic device  101  may try to preferably keep LTE connected. 
     According to an embodiment of the disclosure, the electronic device  101  may divide the user context into at least one class on the basis of a threshold. The threshold may be minimum signal strength to connect Wi-Fi and the electronic device  101 . As the class number is smaller, because there is a higher probability that the electronic device  101  will be connected with LTE, as the class number is smaller, the threshold may become larger. As the class number is larger, because there is a higher probability that the electronic device  101  will be connected with Wi-Fi, as the class number is larger, the threshold may become smaller. For example, a threshold of a video context may be −10 dB, a threshold of a gaming context may be −20 dB, and a threshold of a browsing context may be −30 dB. 
     According to an embodiment of the disclosure, the electronic device  101  may determine network preference of the user. For example, the network preference of the user may be determined based on a ratio at which the user receives data over Wi-Fi. The ratio of the data received over Wi-Fi may be the ratio of an amount of the data received over Wi-Fi to a total amount of data received by the electronic device  101 . For example, when the total amount of data received by the electronic device  101  is 1 GB, when the amount of data received over Wi-Fi is 0.5 GB, and when an amount of data received over a cellular network (e.g., LTE) is 0.5 GB, the ratio of data received over Wi-Fi may be 50%.

     Table 1 is a table in which user preference is written for each user context based on the ratio of data received over Wi-Fi. Referring to Table 1, when the ratio of the data received over Wi-Fi is greater than a first ratio (e.g., 80%), a network the user prefers may be Wi-Fi. Furthermore, when the ratio of the data received over Wi-Fi is greater than or equal to the first ratio, a class number may become larger. For example, because the ratio of the data received over Wi-Fi is 95% when a first user plays a video using a first electronic device, a video context for the first user may have a class (e.g., C 7 ) lower than a video context of  FIG. 2 . 
     According to an embodiment, when the ratio of the data received over Wi-Fi is less than the first ratio and is greater than or equal to a second ratio (e.g., 40% to 60%), the network the user prefers may be set as a network with good communication quality between Wi-Fi or LTE. When a second user searches for materials through browsing, the ratio of the data received over Wi-Fi may be 60%. Thus, the network the second user prefers when searching for the materials may be a network with good communication quality between Wi-Fi or LTE. 
     According to an embodiment, when the ratio of the data received over Wi-Fi is less than the second ratio, the network the user prefers may be LTE. Furthermore, the ratio of the data received over Wi-Fi is less than the second ratio, the class number may become small. For example, because the ratio of the data received over Wi-Fi is 30% when the first user plays an audio using the first electronic device  101 , the audio context for the first user may have a class (e.g., C 2 ) higher than an audio context of  FIG. 2 . 
     According to an embodiment, in Table 1, when a third user searches for materials through browsing or plays a video or audio, the ratio of the data received over Wi-Fi may be greater than or equal to the first ratio. Thus, the browsing context, the video context, and/or the audio context for the third user may have a class (e.g., C 7 ) lower than a browsing context, a video context, and/or an audio context of  FIG. 2 . 
       FIG. 3  illustrates coverage of an access point (AP) according to an embodiment. 
     Referring to  FIG. 3 , an electronic device  101  may set coverage of an AP  301 . For example, when the coverage of the AP  301  is set, information about the coverage may be stored in a memory  130  of the electronic device  101 . The coverage may be an area where the electronic device  101  is able to transmit and receive a signal with the AP  301 . As an embodiment, the electronic device  101  may set the coverage based on a threshold of a user context. For example, when a threshold of a video context is −10 dB and when a threshold of an audio context is 20 dB, coverage  313  for the audio context may be wider than coverage  311  for the video context. For another example, when a threshold of a file transfer context is −30 dB and when a threshold of a messaging context is −40 dB, coverage  317  for the messaging context may be wider than coverage  315  for the file transfer context. 
     According to an embodiment of the disclosure, the electronic device  101  may determine an application executable by the electronic device  101  based at least in part on whether the electronic device  101  is located within coverage. For example, when the electronic device  101  is located within the coverage  311 , because strength of a signal received at the electronic device  101  is greater than the threshold of the video context, a user may execute a video application using Wi-Fi. Furthermore, because the threshold of the video context is the largest value among thresholds of user contexts shown in  FIG. 3 , the strength of the signal received at the electronic device  101  may be greater than the thresholds of all the user contexts shown in  FIG. 3 . Thus, the user may execute an audio application and may execute a message application, using Wi-Fi. 
     Unlike the above-mentioned example, when the electronic device  101  is out of the coverage  311  concurrently with being within the coverage  313 , the strength of the signal received at the electronic device  101  may be greater than the threshold of the audio context and may be less than the threshold of the video context. Thus, when the user executes a video application, the network may change from Wi-Fi to LTE. When the user executes the audio application, the connection with Wi-Fi may be maintained. 
       FIG. 4  illustrates an operational flowchart of an electronic device  101  according to an embodiment. 
     In operation  401  according to an embodiment, the electronic device  101  may be connected with a first network (e.g., Wi-Fi) via a communication circuitry included in the electronic device  101 . The communication circuitry may correspond to, for example, a communication interface  170  shown in  FIG. 1 . For another example, the electronic device  101  may include at least one communication circuitry. 
     In operation  403  according to an embodiment, the electronic device  101  may perform an operation of determining a first user context. The first user context may be data associated with an operation state of the electronic device  101 . For example, when a user plays a video by means of the electronic device  101 , the electronic device  101  may determine the first user context as a video context. For another example, in operation  403 , the electronic device  101  may determine a level of the first user context. In the above-mentioned example, because the first user context is the video context, the electronic device  101  may determine the level of the first user context as C 1 . 
     In operation  405  according to an embodiment, the electronic device  101  may determine whether communication quality of the first network satisfies first communication quality. For example, the communication quality of the first network may be strength of a signal received over Wi-Fi, and the first communication quality may be a threshold of the first user context. That is, the electronic device  101  may compare communication quality of a Wi-Fi network with the threshold of the first user context. When the communication quality of the Wi-Fi network is greater than or equal to the threshold of the first user context as a result of the comparison, the electronic device  101  may maintain the connection between the electronic device  101  and the Wi-Fi network. For example, when a threshold of the video context is −10 dB and when the communication quality of the Wi-Fi network is −5 dB, the electronic device  101  may maintain the connection between the electronic device  101  and the Wi-Fi network. 
     In operation  407  according to an embodiment, when the communication quality of the Wi-Fi network is less than the threshold of the first user context, the electronic device  101  may be connected with a second network (e.g., LTE). In the above-mentioned example, when the communication quality of the Wi-Fi network is −15 dB, the electronic device  101  may change a network to be connected with the electronic device  101  from Wi-Fi to LTE. According to an embodiment of the disclosure, convenience may be provided to the user by connecting a network the user prefers and the electronic device  101 . 
     In an embodiment, the communication quality may vary with link quality and network quality. For example, when link quality between the electronic device  101  and an AP is less than a threshold, real quality of the Wi-Fi network may be identified through the AP. As a result of the identification, whether to switch to LTE may be determined. That is, when network quality between the AP and a network connected with the AP is less than a threshold, the electronic device  101  may change from the Wi-Fi network to an LTE network. When the network quality is greater than or equal to the threshold, the electronic device  101  may maintain Wi-Fi. A description will be given below of an embodiment associated with this with reference to  FIGS. 8 and 9 . 
       FIG. 5A  illustrates an electronic device for changing a network based on a changed user context when the user context is changed, according to an embodiment.  FIG. 5B  illustrates an electronic device for maintaining a network although the user context is changed, according to an embodiment. An embodiment shown in  FIGS. 5A and 5B  may be an example of a flowchart shown in  FIG. 4 . 
     Referring to  FIGS. 5A and 5B , when a user context is changed, an electronic device  101  may maintain a first network or may change to a second network. Whether the user context is changed may be determined based on an operation state of the electronic device  101 , whether an application is executed, an on/off state of a display, or the like. For example, when communication quality of the first network is greater than or equal to a threshold of a changed user context, the electronic device  101  may maintain the first network. According to another embodiment, when the communication quality of the first network is less than the threshold of the changed user context, the electronic device  101  may change the network from the first network to the second network. 
     Referring to  FIG. 5A , when the user context is changed, the electronic device  101  may compare the communication quality of the first network with the threshold of the changed user context. When the communication quality of the first network is less than the threshold of the changed user context as a result of the comparison, the electronic device  101  may change a network connected via its communication circuitry. For example, in  FIG. 5A , a threshold of a messaging context may be −30 dB, communication quality of the first network (e.g., Wi-Fi) may be −20 dB, and a threshold of a video context may be −10 dB. When the user context is changed from the messaging context to the video context, because the communication quality of the first network is less than the threshold of the video context, the electronic device  101  may be connected with the second network (e.g., LTE). 
     Referring to  FIG. 5B , although the user context is changed, the electronic device  101  may maintain a network connected with the electronic device  101 . As an embodiment, when the user context is changed, the electronic device  101  may compare communication quality of the first network (e.g., Wi-Fi) with a threshold of the changed user context. When the communication quality of the first network is greater than or equal to the threshold as a result of the comparison, the electronic device  101  may maintain the connection between the electronic device  101  and the first network. For example, in  FIG. 5B , the threshold of the messaging context may be −30 dB, the communication quality of the first network may be −5 dB, and the threshold of the video context may be −10 dB. Furthermore, the user context may be changed from the messaging context to the video context. Although the user context is changed from the messaging context to the video context, because the communication quality of the first network is greater than the threshold of the video context, the electronic device  101  may maintain the connection between the electronic device  101  and the Wi-Fi network. 
       FIG. 6  illustrates networks connectable to an electronic device and user contexts corresponding to the respective networks according to an embodiment. 
     Referring to  FIG. 6 , an electronic device  101  may be connected with at least one AP via its communication circuitry to use a Wi-Fi network. For example, the electronic device  101  may be connected with the Wi-Fi network via an AP of café A, an AP of restaurant B, an AP of office C, or an AP of mart D. 
     Each AP may provide different signal quality. For example, the electronic device  101  may be configured to display signal quality  601 ,  603 ,  605 , and  607  of the respective APs together on a display of the electronic device  101  when connected to the respective APs. All of signal strength of four Wi-Fi APs is displayed in the example of  FIG. 6 , but it is illustrative. The electronic device  101  may output at least one Wi-Fi AP recognizable in the corresponding location and signal strength thereof on the display  160 . For example, when a user is located in café A and when restaurant B, office C, and mart D are located near café A, the electronic device  101  may detect signals transmitted from APs of café A, restaurant B, office C, and mart D. When the signals transmitted from APs of café A, restaurant B, office C, and mart D are detected, the electronic device  101  may output strength of each signal on the display  160 . 
     According to an embodiment of the disclosure, the electronic device  101  may set a context suitable for an AP based on user behavior. For example, when the user mainly use a video streaming service in café A with a relatively good signal state, the electronic device  101  may determine that the AP of café A is suitable for video streaming. In this example, when the user views a video in café A, the electronic device  101  may maintain the Wi-Fi connection in link quality of a first level. However, when the user views the video in a state where it is connected with another AP, for example, the AP of office C, the electronic device  101  may attempt to switch to an LTE network depending on signal quality (although link quality of the same first level is even obtained). 
     In an additional embodiment, the networks  601 ,  603 ,  605 , and  607  connectable with the electronic device  101  and user contexts suitable for the networks  601 ,  603 ,  605 , and  607  may be matched to be output on the display  160 . For example, because strength of a signal transmitted from the AP of café A is strong, the electronic device  101  may output the network  601  of café A and a video context on the display  160 . Furthermore, because strength of a signal transmitted from the AP of mart D is weak, the electronic device  101  may display the network  607  of mart D and a messaging context on the display  160 . 
     When the networks  601 ,  603 ,  605 , and  607  and the user contexts matched with the networks  601 ,  603 ,  605 , and  607  are output, the user may select and use any one of the output networks. For example, when the user wants to use a video application, he or she may use the network  601  of café A. In  FIG. 8 , it is shown that the electronic device  101  matches each Wi-Fi with the user context to be output on the display  160 . However, the electronic device  101  may match an LTE network  609  with the user context to be output on the display  160 . 
     According to an embodiment of the disclosure, the electronic device  101  may match the networks with the user contexts to be output on the display  160 , thus providing convenience to the user. 
       FIG. 7  illustrates a UI for adjusting Wi-Fi preference based on a user input on a display of an electronic device according to an embodiment. Unlike an embodiment described in Table 1, an embodiment shown in  FIG. 7  is about an embodiment in which a user directly adjusts Wi-Fi preference (or class). 
     Referring to  FIG. 7 , an electronic device  101  may adjust Wi-Fi preference in response to a user input. For example, when the user moves a cursor  703  on a bar  701 , the Wi-Fi preference may vary with a location of the cursor  703 . As the cursor  703  is closer to 0%, the Wi-Fi preference may become lower. As the cursor  703  is closer to 100%, the Wi-Fi preference may become higher. 
     As an embodiment, as the cursor  703  is closer to 0%, because the Wi-Fi preference becomes lower, a threshold of a user context may become large. When the threshold becomes large, because there is a high probability that communication quality will be less than the threshold, there may be a high probability that the electronic device  101  will be connected with LTE. Unlike the above-mentioned example, as the cursor  703  is closer to 100%, because the Wi-Fi preference becomes higher, the threshold of the user context may become small. When the threshold becomes small, because there is a high probability that the communication quality will be greater than the threshold, there may be a high probability that the electronic device  101  will be connected with Wi-Fi. 
     As an embodiment, the electronic device  101  may adjust a class in response to a user input. For example, the user may adjust the class while moving the cursor  703  on the bar  701 . Furthermore, the electronic device  101  may adjust the class for each user context. For example, when the user moves a cursor on a bar corresponding to a video context, a class of the video context may be adjusted. 
     According to an embodiment of the disclosure, the user may directly adjust the Wi-Fi preference such that convenience may be provided to the user. 
       FIG. 8  illustrates an operational flowchart of an electronic device for changing a network from Wi-Fi to LTE according to an embodiment. In an embodiment to be described below, a threshold of a video context may be −10 dB, and a threshold of a browsing context may be −20 dB. 
     In operation  801  according to an embodiment, an electronic device  101  may be connected to a Wi-Fi network. For example, the electronic device  101  may be connected with the Wi-Fi network via at least one communication circuitry included in the electronic device  101 . 
     In operation  803  according to an embodiment, the electronic device  101  may determine quality of the connected network. For example, when the electronic device  101  and Wi-Fi are connected with each other, the electronic device  101  may measure a link condition between the electronic device  101  and Wi-Fi. The link condition may vary with strength of a signal transmitted from an access point (AP) to the electronic device  101 . 
     In operation  805  according to an embodiment, the electronic device  101  may compare the link condition with a first threshold. The first threshold may be the largest value among thresholds of user contexts. For example, the first threshold among thresholds shown in  FIG. 2  may be a threshold of the video context. When the link condition is greater than or equal to the first threshold as a result of comparing the link condition with the first threshold, the electronic device  101  may maintain the connection state between the electronic device  101  and Wi-Fi. For example, when the link condition is −5 dB, because the link condition is greater than thresholds of all user contexts, the electronic device  101  may maintain the connection state between the electronic device  101  and the Wi-Fi network. 
     In operation  807  according to an embodiment, the electronic device  101  may determine a user context. For example, when the link condition is less than the first threshold as a result of the comparison between the link condition and the first threshold, the electronic device  101  may determine the user context. For example, when the link condition is −15 dB, the electronic device  101  may determine the user context. 
     In operation  809  according to an embodiment, the electronic device  101  may compare the link condition with a second threshold. The second threshold may be a threshold of the user context determined in operation  807 . When the link condition is greater than or equal to the second threshold, the electronic device  101  may maintain the connection state between the electronic device  101  and the Wi-Fi network. For example, the link condition may be −15 dB, and the determined user context may be the browsing context. When the link condition is −15 dB, it is less than a threshold of the video context and is greater than a threshold of the browsing context. Thus, when the link condition is greater than or equal to a threshold of the determined user context, the electronic device  101  may maintain the connection state between the electronic device  101  and the Wi-Fi network. 
     In operation  811  according to an embodiment, the electronic device  101  may measure network quality of Wi-Fi. When the link condition is −25 dB, the electronic device  101  may measure the network quality of Wi-Fi. The network quality may vary with strength of a signal transmitted from a network connected with an AP to the AP. The network quality may vary with strength of a signal transmitted and received between a communication circuitry  170  and the network connected with the AP. 
     In operation  813  according to an embodiment, the electronic device  101  may compare the network quality with a specified level. When the network quality is greater than or equal to the specified level as a result of the comparison, the electronic device  101  may maintain the connection state between the electronic device  101  and the Wi-Fi network. When the user context is the browsing context, although the link condition is −25 dB, when the network quality is greater than or equal to the specified level, the electronic device  101  may maintain a network connected with the electronic device  101  as Wi-Fi. According to an embodiment of the disclosure, although the link condition is slightly low, when the network quality is high, the connection between the electronic device  101  and the Wi-Fi network may be maintained. 
     In operation  815  according to an embodiment, the electronic device  101  may change the network connected with the electronic device  101  from Wi-Fi to LTE. When the user context is the browsing context, and when the link condition is −25 dB and when the network quality is less than the specified level, the electronic device  101  may change the network connected with the electronic device  101  from Wi-Fi to LTE. According to an embodiment of the disclosure, the electronic device  101  may measure the link condition and the network quality depending on the user context to provide an optimum environment in which the electronic device  101  may operate to a user. 
       FIG. 9  illustrates an operational flowchart of an electronic device for changing a network from LTE to Wi-Fi according to an embodiment. In  FIG. 9 , a link condition and network quality may correspond to, for example, a link condition and network quality described in  FIG. 8 . In an embodiment to be described below, a threshold of a video context may be −10 dB. 
     In operation  901  according to an embodiment, an electronic device  101  and an LTE network may be connected with each other. For example, the electronic device  101  may be connected with the LTE network via at least one communication circuitry included in the electronic device  101 . 
     In operation  903  according to an embodiment, the electronic device  101  may determine whether there is a Wi-Fi network connectable with the electronic device  101 . When there is no Wi-Fi network connectable with the electronic device  101  as a result of the comparison, the electronic device  101  may maintain the connection between the electronic device  101  and the LTE network. 
     In operation  905  according to an embodiment, the electronic device  101  may determine a user context. For example, when there is the Wi-Fi network connectable with the electronic device  101  as a result of the determination in operation  903 , in operation  905 , the electronic device  101  may determine the user context. 
     In operation  907  according to an embodiment, the electronic device  101  may determine whether a link condition between the electronic device  101  and the Wi-Fi network is greater than or equal to a threshold. The threshold may be a threshold of the user context determined in operation  905 . When the link condition is less than the threshold as a result of the determination, the electronic device  101  may maintain the connection between the electronic device  101  and the LTE network. For example, when the user context is a video context and when the link condition is −15 dB, the electronic device  101  may maintain the connection between the electronic device  101  and the LTE network. 
     In operation  909  according to an embodiment, the electronic device  101  may measure network quality of Wi-Fi. For example, when the link condition is greater than or equal to the threshold as a result of the determination in operation  907 , in operation  909 , the electronic device  101  may measure network quality of Wi-Fi. 
     In operation  911  according to an embodiment, the electronic device  101  may compare the network quality with a specified level. When the network quality is less than the specified level as a result of the comparison, the electronic device  101  may maintain the connection state between the electronic device  101  and the LTE network. For example, when the user context is the video context and when the link condition is −5 dB, although the link condition is greater than the threshold, because the network quality is lower than the specified level, the electronic device  101  may maintain the connection between the electronic device  101  and the LTE network. 
     In operation  913  according to an embodiment, the electronic device  101  may change a network connected with the electronic device  101  from LTE to Wi-Fi. For example, when the user context is the video context, when the link condition is −5 dB, and when the network quality is greater than or equal to the specified level, the electronic device  101  may change the network from LTE to Wi-Fi. According to an embodiment of the disclosure, when the link condition between the electronic device  101  and the Wi-Fi network and the network quality are good, the network may be changed from LTE to Wi-Fi to reduce an amount of data received via the LTE network. 
       FIG. 10  illustrates an operational flowchart of an electronic device  101  connected with Wi-Fi or LTE based on an amount of data received over LTE according to an embodiment. 
     In operation  1001  according to an embodiment, the electronic device  101  may set a limit value of data received over the LTE network. For example, the electronic device  101  may set the limit value of the data received over the LTE network to 5 GB. 
     In operation  1003  according to an embodiment, the electronic device  101  may measure an amount of the data received over the LTE network. The amount of the data received over the LTE network may vary with an operation of the electronic device  101 , executed while the electronic device  101  is connected to the LTE network. For example, there may be more amounts of data when downloading a video over the LTE network than when receiving a message from another user. 
     In operation  1005  according to an embodiment, the electronic device  101  may compare the measured value with the limit value. As a result of the comparison, a network connected with the electronic device  101  may vary with whether the measured value is greater than the limit value. 
     In operation  1007  according to an embodiment, when the measured value is greater than or equal to the limit value, the electronic device  101  may be connected with the Wi-Fi network. In operation  1009  according to an embodiment, when the measured value is less than the limit value, the electronic device  101  may be connected with the LTE network. For example, when the limit value is 5 GB and the measured value is 6 GB, the electronic device  101  may be connected with the Wi-Fi network. When the limit value is 5 GB and when the measured value is 3 GB, the electronic device  101  may be connected with the LTE network. 
     According to an embodiment of the disclosure, when the measured value reaches a predetermined level of the limit value, the electronic device  101  may be configured to be connected with the LTE network. For example, the electronic device  101  may be configured to, when the limit value is 5 GB, be connected with the LTE network when the measured value is 4 GB which is 80% of the limit value. According to an embodiment of the disclosure, the amount of the data received over the LTE network may be limited to prevent communication costs from being increased. 
       FIG. 11  illustrates an electronic device connected with an AP a user prefers and information stored in the electronic device according to an embodiment. 
     Referring to  FIG. 11 , when an electronic device  101  is connected with a network (e.g., Wi-Fi), it may store information  1120 . The information  1120  may store at least one of information associated with a time when the electronic device  101  maintains a connection with the network, the number of times that the connection is released during the time, a type of an application executed during the time, coverage of the network, and/or signal strength of the network. For example, when the electronic device  101  and a Wi-Fi network are connected with each other, a memory  130  may store at least one of a time when a connection between the electronic device  101  and an AP is maintained, the number of times that the connection between the electronic device  101  and the AP is released, a type of an application executed during the time, coverage of Wi-Fi, and signal strength of Wi-Fi. For another example, the information  1120  may include a device usage history  1121  of an electronic device, an application usage history  1122 , a bearer  1123 , a time of day  1124  of the electronic device, hotspot subscription  1125 , a data plan  1126 , other user behavior  1127 , bearer preference  1128 , or the like. 
     A processor  120  may determine an optimum network to be connected with the electronic device  101  using the information  1120  stored in the memory  130 . As an embodiment, as a time when the electronic device  101  is connected with the network is longer and as the number of times that the connection is released during the time is smaller, the processor  120  may determine the network as the optimum network. For example, in  FIG. 11 , a time when the electronic device  101  and AP 1   1101  are connected with each other is 30 hours and a time when the electronic device  101  and AP 2   1103  are connected with each other may be 1 hour. For another example, the number of times that the connection is released during the time when the electronic device  101  and the AP 1   1101  are connected with each other may be 1 time and the number of times that the connection is released during the time when the electronic device  101  and the AP 2   1103  are connected with each other may be 10 times. Thus, the processor  120  may select the AP 1   1101  as an optimum AP to be connected with the electronic device  101  between the AP 1   1101  and the AP 2   1103  and may connect the electronic device  101  and the AP 1   1101 . 
     Unlike the above-mentioned example, the processor  120  may determine the optimum network based on coverage of the network and signal strength of the network. For example, as the coverage of the network is wider and as the signal strength of the network is stronger, the processor  120  may determine the network as the optimum network.
