According to an embodiment, the electronic device 10 may execute a game application 140, which runs in interoperation with an external server (e.g., first server 131 or second server 132). For example, the electronic device 10 may execute the game application in response to an external input (e.g., user input) requesting for execution of the game application 140 and establish a connection to the external server associated with the game application.
According to an embodiment, the first server 131 may be a server for data communication with the electronic device 10 in association with an application running on the electronic device 10. For example, in the case where the game application 140 is running on the electronic device 10, the first server 131 may communicate data associated with the game application with the electronic device 10. Examples of the data associated with the game application 140 may include at least one of background images of the game, game character images, statuses of the game character images, game-related music (sound effects and background music), game stages, statuses of the game stages, and icons to be displayed on a display. According to an embodiment, the game application 140 may have a mode for playing a game in interoperation with the first server 131.
According to an embodiment, the second server 132 may be a server for providing information related to the application running on the electronic device 10. The second server 132 may know the execution status of the application running on the electronic device 10 based on data received from the first server 131. For example, in the case where the game application server is executed in the electronic device 10, the second server 132 may transmit the previously received execution status of the game application 140 to the electronic device 10. The execution status of the application may be the information on the status of the execution of the application running on the electronic device 10 and may be determined based on a usage degree of resources of the electronic device 10 for executing the application. That is, the execution status may be sorted into two categories: high resource usage status and low resource usage status. For example, the resources may include processors, memories, a display, and a sensor module.
However, the situation is not limited to the above description. The second server 132 for providing the electronic device 10 with the application-related information may not exist depending on the application running on the electronic device 10.
According to an embodiment, the electronic device 10 may acquire the data associated with the application running on the electronic device 10. For example, the electronic device 10 may execute the game application 140 and receive character images, background images, and music corresponding to the game application 140 from the first server 131.
According to an embodiment, the electronic device 10 may acquire information on the execution status of the executed application. The application execution status may be determined based on the usage degree of resources of the electronic device for executing the application.
For example, the electronic device 10 may ascertain the game stage and character status of the running game application based on the game application-related data received from the first server 131 and determine the execution status of the application based on whether the usage degree of resources estimated from the game status and the character status is high or low. In this case, if the application execution status is the high resource usage status, this may be at least one of the cases where a plurality of characters appear or a plurality of input signals are capable of being input by the user. If the application execution status is the low resource usage status, this may be at least one of the cases where one character appears, previously stored data are read out for progress to the next episode, the character purchases an item, the character keeps still, or one or two input signals are input repetitively.
According to various embodiments, the electronic device 10 may receive information on the execution status of the game application from the second server. The electronic device 10 may acquire the information on the execution status of the game application from the game application that is running.
According to an embodiment, the electronic device 10 may ascertain (or detect) a temperature of at least part of the electronic device by means of the sensor module (e.g., sensor module 276 in
According to an embodiment, the electronic device 10 may produce heat while the electronic device 10 communicates data with an external device via a network. For example, the electronic device 10 may establish a wireless communication channel with the first cellular network 111 for communication by means of a first communication processor of the electronic device 10. The electronic device 10 may also establish a wireless communication channel with the second cellular network 112 for data communication by means of a second communication processor of the electronic device 10. During the communication process, the first or second communication processor may produce heat. In this case, assuming the second cellular network 112 as a 5G network and the first cellular network 111 as a 2G, 3G, or 4G (or LTE) network, the second communication processor may produce more heat than the first communication processor.
According to an embodiment, the electronic device 10 may produce more heat in the case of using a high resolution display than that in the case of using a low resolution display for displaying an image. For example, a display having pixels 2560×1440 may produce more heat than a display having pixels of 1920×1080.
According to various embodiments, the greater the brightness of the display 11 is, the more electric current the electronic device 10 consumes and the more heat the electronic device 10 produces.
According to an embodiment, charging a battery of the electronic device 10 with power supplied by an external device may produce heat in the battery. Meanwhile, a quick charge function has become a popular feature for recently produced electronic devices. If the quick charge function is used for charging the battery of the electronic device 10, this may produce more heat and higher temperatures than using a normal charge function.
According to an embodiment, the processor of the electronic device 10 may produce more heat depending on the characteristics of an operating system of the electronic device. For example, the operating system of the electronic device 10 may run multiple applications at the same time. For example, the operating system may run multiple applications in such a way of displaying an execution screen of a first application on the display and simultaneously outputting audio sounds of a second application of which the execution screen is not displayed on the display. It may also be possible for the operating system to run multiple applications in such a way of displaying an execution screen of a first application on the display and simultaneously processing data of a second application to prepare for displaying the execution screen of the second application. It may also be possible for the operating system of the electronic device 10 to run multiple applications in such a way of controlling the electronic device 10 to periodically communicate data with an external device to update contents of a predetermined SNS application that is not being executed. Even in this case, the electronic device 10 may produce heat.
According to an embodiment, the electronic device 10 may produce more heat depending on the execution status of an application running on the electronic device 10. For example, the electronic device 10 may generate more heat in the case where multiple characters appear or multiple input signals are allowed to be input than in the case where one character appears or one or two input signals are repetitively input.
According to an embodiment, the electronic device 10 may deactivate the second communication processor based on the ascertained execution status and temperature.
For example, the electronic device 10 may include the first communication processor (e.g., first communication processor 312 in
For example, the first communication processor may establish a wireless communication channel with the first cellular network 111 supporting 2G, 3G, or 4G (or LTE) communication. The second communication processor may establish a wireless communication channel with the second cellular network 112 supporting 5G communication. That is, the electronic device 10 may switch from the 5G communication to the 2G, 3G, or 4G (LTE) communication based on the application execution status and detected temperature. In this manner, the electronic device 10 may reduce its internal heat production.
For example, the electronic device 10 may detect an execution status of a game application in which a character repeats the same action, i.e., low resource usage status. The electronic device 10 may detect that the sensed temperature of the electronic device 10 is close to a predetermined value (e.g., in the range between 40° C. and 45° C.). In this case, the electronic device 10 may deactivate the second communication processor and simultaneously activate the first communication processor for data communication with the external device.
According to various embodiments, the electronic device 10 may control antenna modules with different frequency bands based on the application execution status and sensed temperature. For example, the electronic device 10 may be controlled to use an antenna operating in a frequency band below 6 gigahertz (GHz) (e.g., second antenna module 344 in
For example, if the execution status of the game application indicates the high resource usage status of the electronic device 10 or if the temperature of the electronic device 10 is close to the predetermined value (e.g., in the range between 40° C. and 45° C.), the electronic device 10 may deactivate the communication channel established by the antenna operating in the first frequency band (e.g., frequency band between 6 GHz and 60 GHz) and activate the communication channel established by the antenna operating in the second frequency band (e.g., frequency band below 6 GHz).
A wireless communication module including the first and second communication processors is described later with reference to
According to an embodiment, the electronic device 10 may activate the second communication processor in the case where the network traffic being processed by the first communication processor is greater than a predetermined threshold.
The electronic device 10 may measure the network traffic in the course of data communication with the first server 131 or the second server 132 via a 2G, 3G, or 4G (or LTE) communication network. For example, if the network traffic becomes equal to or greater than a predetermined threshold (e.g., 400 megabyte (mb)˜500 mb), the electronic device 10 may activate a connection to the second cellular network 112 for 5G communication.
For example, if multiple characters appear in the game application running on the electronic device 10, the electronic device 10 may detect that the game application transitions to an execution status requiring download of a high volume of data. The electronic device 10 may activate the second cellular network 112 corresponding to 5G communication for receiving the large volume of data quickly from the first server 131.
In this case, the electronic device 10 may determine whether the electronic device 10 is located in an area available for access to a 5G network. For example, if the electronic device 10 is located in an area where the connection to the second cellular network 112 is frequently broken, it may maintain the connection to the first cellular network 111 for data communication.
According to various embodiments, the electronic device 10 may control the antenna modules operating in different frequency bands based on the ascertained application execution status and temperature. For example, if it is determined that the execution status of the game application indicates the necessity of a download of a high volume of data, the electronic device 10 may deactivate the communication channel established by means of the antenna operating in the second frequency band (e.g., frequency band below 6 GHz) and activate a communication channel established by means of the antenna operating in the first frequency band (e.g. frequency band between 6 GHz and 60 GHz).
According to various embodiments, the second communication processor may operate under the control of the second communication processor. For example, the second communication processor may be activated or deactivated under the control of the first communication processor staying in the activated state.
For example, the electronic device 10 may deactivate the second communication processor under the control of the first communication processor based on the ascertained application execution status and temperature. Deactivating the second communication processor may mean transitioning the second communication processor to a maximum power-saving status.
In this case, the electronic device 10 may control the first communication processor such that a signal (or data) received form the second cellular network 112 via the second antenna module (e.g., second antenna module 344 in
The electronic device 10 may also activate the second communication processor under the control of the first communication processor in the case where the network traffic being processed by the first communication processor for execution of an application is greater than a predetermined threshold.
According to an embodiment, the electronic device 10 may deactivate the first communication processor and activate the second communication processor. The electronic device 10 may maintain the data communication via the first communication processor, even when the second communication processor is activated, until the data communication continuity is guaranteed for the processing operation of the second communication processor.
For example, the electronic device 10 may check the game data communication history between the first and second communication processors and verify the continuity of the game data communicated with the first server 131. The electronic device 10 may deactivate the first communication processor and then proceed to activate the second communication processor for game data communication with the first server 131. That is, the electronic device 10 may control the first and second communication processors such that the data communication operation with the first communication processor and the data communication operation with the second communication processor are overlapped.
According to this embodiment, the electronic device is capable of switching between communication channels dynamically based on the temperature status of the electronic device 10 and the execution status of the application running on the electronic device 10, thereby achieving the goals of reducing heat production of the electronic device and maintaining performance of an application running on the electronic device.

For reception, an RF signal from the first cellular network 392 (e.g., legacy network) may be received by an antenna (e.g., first antenna module 342) and preprocessed by an RFFE (e.g., first RFFE 332). The first RFIC 322 may convert the preprocessed RF signal to a baseband signal that can be processed by the first communication processor 312.
For transmission, the second RFIC 324 may convert the baseband signal generated by the first communication processor 312 or the second communication processor 314 to an RF signal for use in the second cellular network (hereinafter, referred to as Sub6 RF signal). For reception, a 5G Sub6 RF signal from the second cellular network 394 (e.g., 5G network) may be received by an antenna (e.g., second antenna module 344) and preprocessed by an RFFE (e.g., second RFFE 334). The second RFIC 324 may convert the preprocessed 5G Sub6 RF signal to a baseband signal that can be processed by one of the first and second communication processor 312 and 314.
The third RFIC 326 may convert the baseband signal generated by the second communication processor 314 to an RF signal of a 5G Above6 band (e.g., about 6 GHz˜about 60 GHz) (hereinafter, 5G Above6 RF signal) for use in the second cellular network 394 (e.g., 5G network). For reception, a 5G Above6 RF signal from the second cellular network 394 (e.g., 5G network) may be received by an antenna (e.g., antenna 348) and preprocessed by the third RFFE 336. The third RFIC 326 may convert the preprocessed 5G Above6 RF signal to a baseband signal that can be processed by the second communication processor 314. According to an embodiment, the third RFFE 336 may constitute part of the third RFIC 326.
According to an embodiment, the electronic device 201 may include the fourth RFIC 328 formed independently of or as at least part of the third RFIC 326. In this case, the fourth RFIC 328 may convert the baseband signal generated by the second communication processor 314 to an intermediate frequency (IF) band (e.g., about 9 GHz˜about 11 GHz) signal (hereinafter, referred to as IF signal) and send the IF signal to the third RFIC 326. The third RFIC 326 may convert the IF signal to a 5G Above6 RF signal. For reception, a 5G Above6 RF signal from the second cellular network 394 (e.g., 5G network) may be received by an antenna (e.g., antenna 348) and converted to an IF signal by the third RFIC 326. The fourth RFIC 328 may convert the IF signal to a baseband signal that can be processed by the second communication processor 314.
According to an embodiment, the first and second RFICs 322 and 324 may constitute at least part of a single chip or a signal package. According to an embodiment, the first and second RFFEs 332 and 334 may constitute at least part of a single chip or a single package. According to an embodiment, at least one of the first and second antenna modules 342 and 344 may be omitted or combined with another antenna module to process RF signals in the corresponding bands.
According to an embodiment, the third RFIC 326 and the antenna 348 may be arranged on the same substrate as the third antenna module 346. For example, the wireless communication module or the processor 220 may be arranged on a first substrate (e.g., main PCB). In this case, the third antenna module 346 may be formed in such a way of arranging the third RFIC 326 at a region (e.g., bottom surface) of a second substrate (e.g., sub PCB) in separation from the first substrate and the antenna 348 at another region (e.g., top surface) of the second substrate. By arranging the third RFIC 326 and the antenna 348 on the same substrate, it may be possible to reduce the length of a transmission line between the third RFIC 326 and the antenna 348. This makes it possible to reduce loss (attenuation) of signals in a high frequency band (e.g., about 6 GHz˜about 60 GHz) for 5 network communication on the transmission line. This means that the electronic device 201 can improve the quality and speed of communication with the second cellular network 394 (e.g., 5G network).
According to an embodiment, the antenna 348 may be configured in the form of an antenna array including a plurality of antenna elements for beamforming. In this case, the third RFIC 326 may include, as part of the third RFFE 336, a plurality of phase sifters 338 corresponding to the antenna elements. For transmission, each phase shifter 338 may shift the phase of a 5G Above6 RF signal to be transmitted to the outside (e.g., 5G network base station) of the electronic device 201 via a corresponding antenna element. For reception, the phase shifters 338 may shift the phases of 5G Above6 RF signals received from the outside via corresponding antenna elements so as to be identical or substantially identical with each other. This makes it possible for the electronic device to perform beamforming for transmitting and receiving signals to and from the outside.
The second cellular network 394 (e.g., 5G network) may operate independently of (e.g., standalone (SA)) or in association with (e.g., non-standalone (NSA)) the first cellular network 392 (e.g., legacy network). For example, a 5G network may include access networks (e.g., 5G radio access networks (RANs) or next generation RANs (NG RANs)) with the exception of a core network (e.g., N core). In this case, the electronic device 201 may access the 5G RAN to connect to an external network (e.g., Internet) under the control of a core network of a legacy system (e.g., evolved packet core (EPC). The protocol information for communication with the legacy network (e.g., LTE protocol information) and the protocol information for communication with the 5 network (e.g., New Radio (NR) protocol information) may be stored in the memory 330 such that other components (e.g., processor 220, first communication processor 312, or second communication processor 314) can access the information.
