[0061] As shown in Figure 4, within the server 10, a virtual mobile client terminal corresponding to each mobile client terminal 100 is configured. That is, within the server 10, a virtual mobile client terminal 100A' corresponding to mobile client terminal 100A may be configured. Furthermore, within the server 10, a virtual mobile client terminal 100B' corresponding to mobile client terminal 100B may be configured. In addition, within the server 10, a virtual mobile client terminal 100C' corresponding to mobile client terminal 100C may be configured.

[0062] In the virtual mobile client terminal container group 100' shown in Figure 4, three virtual mobile client terminals are configured. Thus, in one embodiment of system 1, the server 10 may configure the same number of virtual mobile client terminals as the number of mobile client terminals 100 connected to the server 10.

[0063] As shown in Figure 4, for example, multiple users can be invited to the server 10 by configuring multiple virtual mobile client terminals on a single server 10. As shown in Figure 4, operations / text inputs from each mobile client terminal 100 are transmitted to the server 10. When the server 10 receives operations / text inputs from each mobile client terminal 100, it configures a screen to be displayed on the display unit 110 of each mobile client terminal 100 according to the respective operations / text inputs. Next, the server 10 transmits the screen data to be displayed on the display unit 110 of each mobile client terminal 100 to each mobile client terminal 100. When each mobile client terminal 100 receives the screen data to be displayed on the display unit 110, it can display a screen based on the received data on its respective display unit 110.

[0064] Here, the server 10 can receive different operations / text inputs from multiple mobile client terminals 100, generate different screen data for each, and send it to each mobile client terminal 100. In one embodiment, each time a user starts using each mobile client terminal 100, the server 10 starts the corresponding virtual mobile client terminal and sends its contents to each mobile client terminal 100.

[0065] If the above operations can be completed on server 10, server 10 may control each mobile client terminal 100 by communicating with each mobile client terminal 100. Alternatively, as shown in Figure 4, a separate management server 200 may be used to centrally manage the virtual mobile client terminals of all mobile client terminals 100.

[0066] In System 1 shown in Figure 4, each mobile client terminal 100 simply transmits the data it has operated / input to the server 10, and displays the screen based on the data transmitted from the server 10 on its respective display unit 110. Therefore, in System 1 according to one embodiment, it is possible to construct a thin client system that reduces the processing load on the mobile client terminal 100 used by the user and concentrates most of the main processing on the server 10.

[0067] On the other hand, in System 1 as shown in Figure 4, various problems may occur if the settings related to the predetermined devices equipped on each mobile client terminal 100 are not properly configured according to various circumstances. In other words, problems may occur if the mobile client terminal 100 is operated in the same way as a general thin client system. The following describes these possible problems and countermeasures.

[0068] For example, as shown in Figure 5A, we can assume a scenario where the screen of the display unit 110 is scrolled in response to user input on the mobile client terminal 100.

[0069] Figure 5A shows an example of a scenario in which an application, such as an internet browser, is launched on a mobile client terminal 100 and search results from a search engine are displayed. As shown in Figure 5A, the display unit 110 of the mobile client terminal 100 is displaying the application display area AD. Here, the application display area AD may be the display area of ​​the screen that is displayed based on the launch or execution of various applications.

[0070] The application display area AD shown in Figure 5A lists the search results (products) obtained from the search engine. When the display area is relatively small, such as the display unit 110 of the mobile client terminal 100, it may not be possible to display all the content on one screen. For this reason, in many cases, mobile terminals allow the screen to be scrolled in response to user input. For example, suppose the user performs an operation such as sliding, swiping, or flicking from the bottom to the top of the screen on the display unit 110, as indicated by the arrow SC in Figure 5A. In this case, the mobile client terminal 100 can scroll the application display area AD displayed on the display unit 110 upwards in response to this operation.

[0071] Figure 5B shows an example where the application display area AD displayed on the display unit 110 changes as a user performs an input operation such as sliding in Figure 5A. In Figure 5B, product A, which was displayed in Figure 5A, moves upward, and product B, which was not displayed in Figure 5A, is newly displayed. Furthermore, for example, suppose the user performs an operation such as sliding, swiping, or flicking from the bottom to the top of the screen on the display unit 110, as shown by the arrow SC in Figure 5B. If there is still an area not displayed on the display unit 110, the mobile client terminal 100 can scroll the application display area AD displayed on the display unit 110 upward in response to the operation.

[0072] Figure 5C shows an example where the application display area AD displayed on the display unit 110 changes after the user performs input operations such as sliding in Figure 5B. In Figure 5C, product B, which was displayed in Figure 5B, moves upward, and product C, which was not displayed in Figure 5B, is newly displayed.

[0073] As shown in Figures 5A to 5C, when scrolling a display screen, the displayed content changes rapidly during scrolling, and the area where the displayed content changes is often relatively large. For this reason, in a typical thin client system, the amount of data transferred from the server to the client (data necessary for displaying the screen) tends to increase during scrolling. Consequently, when scrolling the screen on a mobile client terminal 100, the amount of data transmitted may increase during scrolling. In particular, in mobile applications, an increase in data transmission charges can lead to an increase in usage costs.

[0074] Furthermore, as the amount of screen data transferred from the server 10 to the mobile client terminal 100 increases, the processing load on the mobile client terminal 100 also tends to increase. If the processing of the mobile client terminal 100 is delayed due to the increased processing load, the smoothness (rendering) of the screen display on the display unit 110 may be lost.

[0075] Furthermore, even outside of screen scrolling, the amount of screen data may increase or the processing load on the mobile client terminal 100 may increase depending on the state of the mobile client terminal 100, such as the communication environment and / or battery level, or changes in such state. In such cases, the user experience may also be degraded.

[0076] Therefore, in System 1 according to one embodiment, the amount of screen data transferred from the server 10 to the mobile client terminal 100 is changed when, for example, the display unit 110 of the mobile client terminal 100 is scrolling or in a predetermined state. More specifically, in System 1 according to one embodiment, the amount of screen data transferred from the server 10 to the mobile client terminal 100 may be reduced when, for example, the display unit 110 of the mobile client terminal 100 is scrolling or in a predetermined state. Such embodiments will be described further below.

[0077] Next, the operation of System 1 according to one embodiment will be described in more detail. Figure 6 is a flowchart illustrating the operation of System 1 according to one embodiment.

[0078] The operations described in Figure 6 and subsequent figures are described as operations of System 1 according to one embodiment. Each operation and / or process described in Figure 6 and subsequent figures may be performed by at least one of the server 10 and the mobile client terminal 100 according to one embodiment. For example, at least a portion of each operation and / or process described in Figure 6 and subsequent figures may be performed by the server 10 if it can be completed as an operation by the server 10. Also, at least a portion of each operation and / or process described in Figure 6 and subsequent figures may be performed by the mobile client terminal 100 if it can be completed as an operation by the mobile client terminal 100. Furthermore, at least a portion of each operation and / or process described in Figure 6 and subsequent figures may be performed by the server 10 and the mobile client terminal 100 working together, if possible.

[0079] When the operation shown in Figure 6 begins, in the system 1 according to one embodiment, the mobile client terminal 100 detects user input and, if such input is present, generates data based on that input (step S11). Next, the mobile client terminal 100 sends the generated data (data based on user input) to the server 10 (step S12).

[0080] When server 10 receives data based on user input from mobile client terminal 100, it generates display screen data corresponding to said input (step S13). Next, server 10 modifies the amount of generated data according to the state of mobile client terminal 100 or a change in said state (step S14).

[0081] For example, in step S14, if the display on the display unit 110 of the mobile client terminal 100 is scrolling, the server 10 may reduce the amount of data generated in step S13. Also, in step S14, if the display on the display unit 110 of the mobile client terminal 100 is scrolling, the server 10 may reduce the amount of data generated in step S13 according to the degree of scrolling. For example, the amount of data may be reduced as the degree of scrolling increases.

[0082] To perform the operation in step S14, the server 10 may determine whether the mobile client terminal 100 is in a predetermined state or whether a predetermined change has occurred in the state of the mobile client terminal 100. For this purpose, the server 10 may periodically or as needed acquire or receive a predetermined signal indicating the state of the mobile client terminal 100. Alternatively, the server 10 may acquire or receive a predetermined signal indicating the state of the mobile client terminal 100 in advance and start the operation in step S14, for example, triggered by the arrival of a predetermined timing.

[0083] Next, the server 10 sends the data (the data on the display screen), whose quantity has been appropriately modified, to the mobile client terminal 100 (step S15).

[0084] When the mobile client terminal 100 receives display screen data from the server 10, it displays a screen based on that display screen data on the display unit 110 (step S16). Through this operation, in system 1, if the mobile client terminal 100 is in a predetermined state, or if a change in that state occurs, the amount of display screen data transmitted from the server 10 is changed (for example, reduced). Therefore, for example, when the display on the display unit 110 is scrolled on the mobile client terminal 100, the amount of display screen data transmitted from the server 10 is reduced, and the amount of data processed on the mobile client terminal 100 is also reduced.

[0085] In the embodiment shown in Figure 6, the amount of data for the display screen generated by the server 10 was modified on the server 10. In one embodiment, the data for the display screen generated by the server 10 may be transmitted to the mobile client terminal 100, and the amount of data for the display screen may be modified on the mobile client terminal 100. Such embodiments will be briefly described below.

[0086] Figure 7 is a flowchart illustrating the operation of System 1 according to one embodiment. In Figure 7, the main points to be explained are those that differ from those in Figure 6, and explanations that are the same as or similar to those in Figure 6 are simplified or omitted as appropriate.

[0087] The operations in steps S11 to S13 shown in Figure 7 may be performed in the same manner as the operations in steps S11 to S13 shown in Figure 6.

[0088] As shown in Figure 7, after generating screen display data in step S13, the server 10 may transmit the data to the mobile client terminal 100 (step S21). In this case, the mobile client terminal 100 may change the amount of the received data according to the state of the mobile client terminal 100 or a change in that state (step S22). For example, in step S14, if the display on the display unit 110 of the mobile client terminal 100 is scrolling, the mobile client terminal 100 may reduce the amount of data received in step S21. Next, the mobile client terminal 100 may display a screen on the display unit 110 based on the data of the display screen, with the amount of data appropriately changed (step S16).

[0089] Next, we will further explain the effects of the operation of System 1 according to one embodiment shown in Figures 6 and 7.

[0090] Figures 8A to 8D illustrate an example of operation by System 1 according to one embodiment. Figures 8A to 8D show a situation similar to that described in Figures 5A to 5C above.

[0091] Figure 8A, similar to Figure 5A described above, shows a scenario in which the screen of the display unit 110 is scrolled in response to user input on the mobile client terminal 100. Here, for example, suppose the user performs an operation such as sliding, swiping, or flicking from the bottom to the top of the screen on the display unit 110, as indicated by the arrow SC in Figure 8A. In this case, in response to the operation, the mobile client terminal 100 scrolls the application display area AD displayed on the display unit 110 upwards.

[0092] Figure 8B shows an example where the application display area AD displayed on the display unit 110 changes after the user performs input operations such as slide input in Figure 8A. In Figure 8B, product A, which was displayed in Figure 8A, moves upward, and product B, which was not displayed in Figure 5A, is newly displayed. Also, in Figure 8B, (unlike the situation shown in Figure 5B,) the resolution of the entire screen of the display unit 110 (including products A and B) is reduced in conjunction with the slide input operation (scrolling). In Figure 8B, the reduced resolution of products A and B displayed on the display unit 110 is shown by dashed lines.

[0093] Furthermore, for example, suppose the user performs an operation such as sliding, swiping, or flicking from the bottom to the top of the screen on the display unit 110, as indicated by the arrow SC in Figure 8B. If there is still an area not displayed on the display unit 110, the mobile client terminal 100 can scroll the application display area AD displayed on the display unit 110 upwards in response to this operation.

[0094] Figure 8C shows an example where the application display area AD displayed on the display unit 110 changes after further input operations such as the user sliding are performed in Figure 8B. In Figure 8C, product B, which was displayed in Figure 8B, moves upward, and product C, which was not displayed in Figure 8B, is newly displayed. Also, in Figure 8C, the resolution of product C, which is newly displayed as the slide progresses, is reduced. In Figure 8C, the reduced resolution of product C is shown by a dashed line. Thus, in system 1 according to one embodiment, the mobile client terminal 100 may reduce the display resolution during the scrolling of the application display area AD displayed on the display unit 110.

[0095] Figure 8D shows the state after Figure 8C, when the user stops performing input operations such as sliding, and the scrolling of the application display area AD displayed on the display unit 110 stops. As shown in Figure 8D, when the scrolling of the display on the display unit 110 stops, the application display area AD displayed on the display unit 110 may perform its original (unreduced resolution) screen display. In Figure 8C, the resolution of the images of products B and C was reduced, but in Figure 8D, the resolution of the images of products B and C is not reduced.

[0096] In one embodiment of System 1, as shown in Figures 8B and 8C, for example, even if the image resolution is slightly reduced while the display on the display unit 110 is scrolling, it is considered that the user experience will not be significantly degraded. Furthermore, by reducing the image resolution while the display on the display unit 110 is scrolling, the amount of screen data processed by the mobile client terminal 100 can be reduced. Therefore, the processing load on the mobile client terminal 100 can also be reduced. Reducing the processing load reduces the risk of processing delays in the mobile client terminal 100 and also reduces the risk of loss of smoothness (rendering) of the screen display on the display unit 110.

[0097] In this embodiment of System 1, the server 10 communicates with the mobile client terminal 100 via the network N. Here, the server 10 generates data for the display screen of a virtual mobile client terminal corresponding to the mobile client terminal 100. The mobile client terminal 100 also includes a display unit 110. The display unit 110 displays the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100.

[0098] Furthermore, in the system 1 according to one embodiment, the amount of data constituting the screen of the application display area displayed on the display unit 110 is changed in accordance with the state of the mobile client terminal 100 or a change in that state. More specifically, in the system 1 according to one embodiment, the amount of data constituting the screen of the application display area displayed on the display unit 110 may be reduced in accordance with the state of the mobile client terminal 100 or a change in that state.

[0099] As described above, the amount of data constituting the screen of the display area in the display unit 110 may be changed by the server 10. That is, while the screen displayed on the display unit 110 of the mobile client terminal 100 is being scrolled, the server 10 may reduce the amount of data constituting the screen of the application display area displayed on the display unit 110 that it sends to the mobile client terminal 100. While the screen displayed on the display unit 110 of the mobile client terminal 100 is not being scrolled, the server 10 does not need to reduce the amount of data constituting the screen of the application display area displayed on the display unit 110 that it sends to the mobile client terminal 100.

[0100] As described above, when changing the amount of data in the server 10, more specifically, it may operate as follows: The mobile client terminal 100 may send data based on user input from the mobile client terminal 100 to the server 10. The mobile client terminal 100 may also receive data from the display screen of a virtual mobile client terminal corresponding to the mobile client terminal 100, generated by the server 10. The mobile client terminal 100 may then display the application display area screen on the display unit 110 based on the data from the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100. In one embodiment, the mobile client terminal 100 may display the display screen data sent from the server 10 to match the size of the display area of ​​the display unit 110.

[0101] Furthermore, when changing the amount of data in server 10, it may operate more specifically as follows: Server 10 may generate data for the display screen of a virtual mobile client terminal corresponding to the mobile client terminal 100. Server 10 may also receive data from the mobile client terminal 100 based on user input on the mobile client terminal 100. Server 10 may also reduce the amount of data that constitutes the application display area screen displayed on the display unit 110 while the screen displayed on the display unit 110 of the mobile client terminal 100 is being scrolled.

[0102] Furthermore, as described above, the amount of data constituting the screen of the display area in the display unit 110 may be changed on the mobile client terminal 100. That is, while the screen displayed on the display unit 110 of the mobile client terminal 100 is being scrolled, the mobile client terminal 100 may reduce the amount of data constituting the screen of the application display area displayed on the display unit 110. Also, while the screen displayed on the display unit 110 of the mobile client terminal 100 is not being scrolled, the mobile client terminal 100 does not need to reduce the amount of data constituting the screen of the application display area displayed on the display unit 110.

[0103] In one embodiment, the condition for reducing the resolution of the screen data transferred from the server 10 to the mobile client terminal 100 may be, for example, that the amount of movement due to scrolling on the display unit 110 in the mobile client terminal 100 is greater than or equal to a threshold. Alternatively, the condition for reducing the resolution of the screen data transferred from the server 10 to the mobile client terminal 100 may be, for example, that an instruction has been received from the mobile client terminal 100.

[0104] As described above, in one embodiment of the system 1, the resolution of the application display area screen displayed on the display unit 110 of the mobile client terminal 100 may be reduced while the screen displayed on the display unit 110 is being scrolled. Alternatively, in one embodiment of the system 1, the resolution of the application display area screen displayed on the display unit 110 may not be reduced while the screen displayed on the display unit 110 of the mobile client terminal 100 is not being scrolled.

[0105] (Other embodiments) Next, we will further describe System 1 according to another embodiment.

[0106] In the embodiment described above, the resolution of the screen displayed on the display unit 110 was reduced while the screen of the mobile client terminal 100 was scrolling. In system 1 according to one embodiment, while the screen of the mobile client terminal 100 is scrolling, the frame rate of the screen displayed on the display unit 110 may be reduced instead of, or along with, the resolution of the screen displayed on the display unit 110. That is, in one embodiment, while the screen displayed on the display unit 110 of the mobile client terminal 100 is scrolling, the frame rate of the application display area screen displayed on the display unit 110 may be reduced. Also, while the screen displayed on the display unit 110 of the mobile client terminal 100 is not scrolling, it is not necessary to reduce the frame rate of the application display area screen displayed on the display unit 110.

[0107] In the above-described embodiment, operations such as reducing the amount of data displayed on the screen were performed depending on whether or not the screen of the mobile client terminal 100 was scrolled. In one embodiment, operations such as reducing the amount of data displayed on the screen may also be performed depending on whether or not the mobile client terminal 100 is in a predetermined state, or whether or not a predetermined change has occurred in the state of the mobile client terminal 100.

[0108] For example, if the communication environment of the mobile client terminal 100 is relatively poor, actions such as reducing the amount of data displayed on the screen may be taken. In such cases, as a specific example of reducing the amount of data displayed on the screen, for example, the resolution of the screen displayed on the display unit 110 may be reduced. Also, in the above-mentioned cases, as a specific example of reducing the amount of data displayed on the screen, for example, the frame rate of the screen displayed on the display unit 110 may be reduced. Furthermore, for example, if the environment in which the mobile client terminal 100 communicates with the server 10 does not meet a predetermined standard, the amount of data constituting the screen of the application display area displayed on the display unit 110 may be reduced.

[0109] Furthermore, for example, if the communication environment of the mobile client terminal 100 is relatively good, actions such as increasing the amount of data displayed on the screen may be taken. In such cases, as a specific example of increasing the amount of data displayed on the screen, for example, the resolution of the screen displayed on the display unit 110 may be increased. Also, as a specific example of reducing the amount of data displayed on the screen in the above-mentioned case, for example, the frame rate of the screen displayed on the display unit 110 may be increased. Furthermore, for example, if the environment in which the mobile client terminal 100 communicates with the server 10 meets a predetermined standard, the amount of data constituting the screen of the application display area displayed on the display unit 110 may be increased. Also, for example, if the environment in which the mobile client terminal 100 communicates with the server 10 does not meet a predetermined standard, the amount of data constituting the screen of the application display area displayed on the display unit 110 may not be increased.

[0110] In the above-mentioned case, the quality of the communication environment may be determined based on parameters indicating the strength or quality of radio waves, such as RSRP (Reference Signal Received Power). Alternatively, in the above-mentioned case, the quality of the communication environment may be determined based on parameters such as RTT (Round Trip Time) and / or the processing time of one screen frame.

[0111] Furthermore, in system 1 according to one embodiment, for example, when the battery charge level of the mobile client terminal 100 falls below a predetermined level, operations such as reducing the amount of data displayed on the screen may be performed. In this way, the processing load on the mobile client terminal 100 can be reduced when the battery charge level of the mobile client terminal 100 falls below a predetermined level.

[0112] Furthermore, in System 1 according to one embodiment, operations such as reducing the amount of data displayed on the screen may be performed based on whether the orientation of the mobile client terminal 100 is vertical or horizontal. Also, in System 1 according to one embodiment, operations such as reducing the amount of data displayed on the screen may be performed based on whether the network environment in which the mobile client terminal 100 communicates is, for example, Wi-Fi or mobile communication.

[0113] Furthermore, in the system 1 according to one embodiment, operations such as reducing the amount of data displayed on the screen may be performed based on, for example, the temperature of a predetermined part of the mobile client terminal 100. Also, in the system 1 according to one embodiment, operations such as increasing the amount of data displayed on the screen (increasing the resolution) may be performed when, for example, the camera is capturing an image in the mobile client terminal 100.

[0114] Furthermore, in System 1 according to one embodiment, operations such as reducing the amount of data displayed on the screen may be performed based on, for example, the CPU load of the mobile client terminal 100. Also, in System 1 according to one embodiment, operations such as increasing the amount of data displayed on the screen (increasing the resolution and / or frame rate) may be performed if, for example, video playback is in progress on the mobile client terminal 100.

[0115] According to one embodiment of System 1, the amount of screen data transferred from the server 10 to the mobile client terminal 100 can be reduced in certain cases. Furthermore, because the amount of data displayed on the screen can be reduced, usage costs (data communication charges) can be reduced. In addition, according to one embodiment of System 1, the processing load on the mobile client terminal 100 can be reduced, and the user can be provided with a smooth scrolling experience. Because the processing load on the mobile client terminal can be reduced according to one embodiment of System 1, a reduction in battery consumption can also be expected. Furthermore, according to one embodiment of System 1, even if the communication environment deteriorates to some extent, the user of the mobile client terminal 100 can maintain a certain level of operability and continue using the application.
