Description

  The present invention relates to a portable device that switches a user interface according to a detected wireless network.

  Today, telephone calls and data communication are frequently performed using mobile devices such as mobile phones and PDAs. Such services such as telephone calls and data communication are generally made using a mobile phone network, which is a public communication network. However, in recent years, wireless LANs have been widely used, and IP-based telephone calls using wireless LANs have been promoted. The development of systems and broadband networks that can send and receive large amounts of data in a short time is also remarkable.

  Wireless LANs have become widespread as so-called public communication networks (public wireless LANs) that can be used in the city by unspecified or contracted users. However, they are widely used in homes (home networks) and businesses (intranets, IP centrex). The spread is also remarkable. As described above, communication via a wireless network can be performed at various places such as homes, towns, outdoors, and offices, and users can use wireless network services everywhere.

  On the other hand, mobile devices are equipped with various functions year by year. For example, in mobile phones, there are models that can make IP-based (VoIP) calls via a wireless LAN in addition to conventional calls via a mobile phone network. In addition, a mail transmission / reception function, a music data download function, a WEB browser function, and the like are also installed in most mobile phones. In addition, as a function not via a wireless network capable of transmitting and receiving data, there are various functions such as a remote control function for home appliances, a music / video playback function, and an imaging function.

  As described above, wireless networks can be used in various places at present, but if it is necessary to use dedicated communication terminals for each wireless network, it is necessary to carry as many communication terminals as the number of wireless networks to be used. As a result, the user's convenience is significantly impaired.

  In this case, if one communication terminal can cope with a plurality of wireless networks, this problem can be reduced. Currently, for example, when you are in the home network communication area set in your home, you are on the IP phone via the wireless LAN, but you are outside the home network communication area when you are out Sometimes mobile phones are available that function to make calls over the mobile phone network.

Further, Patent Document 1 proposes a mobile terminal device that automatically switches to a call means via a telephone network when a connection state deteriorates during a call by a call means via a LAN.

  Since the mobile device of the present invention is automatically changed to a user interface corresponding to the wireless network environment, the user operates the mobile device with a user interface that is used more frequently, for example, depending on the situation and location. The user convenience can be further improved.

  First, an overview of a network system in which the mobile device 100 according to an embodiment of the present invention is used will be described with reference to FIG. The mobile device 100 is, for example, a mobile terminal such as a mobile phone or a PDA. Here, a mobile phone will be described as an example. The upper part of FIG. 1 shows a state in which the mobile device 100 communicates with the base station 20 via the wireless network and is connected to the mobile phone network 25. This is a general communication mode when making a call or mail with a mobile phone. The mobile device 100 is connected to another mobile device (mobile phone) connected to the mobile phone network 25, a server, and the like, and transmits and receives voice data, mail data, and the like. A display screen of the mobile device 100 when the user is not operating usually displays a telephone standby screen. When a call is in progress or a mail operation is performed, a screen corresponding to the situation is displayed.

  The lower part of FIG. 1 shows a case where the mobile device 100 has moved to the vicinity of the network site 50 and the network site 60. The network site 50 and the network site 60 are home networks constructed in each home, for example. In the network site 50, an access point 51, an IP phone 53, and a PC (personal computer) 54 are connected to each other by a wired network 55. In this example, the television 52 is also connected to the network 55.

  As shown in the lower part of FIG. 1, when the mobile device 100 moves and enters the communication area of the access point 51, the remote control operation application is automatically executed in the mobile device 100, and the display device of the mobile device 100 waits for standby. The screen is automatically switched to the remote control operation screen (changes in the display screen of the display device of the portable device 100 will be described in detail later). Here, when the user presses the push button of the mobile device 100, a remote control signal 40 is transmitted. In this example, the remote control signal 40 is a signal for designating the channel of the television 52.

  The push button of the mobile device 100 is used to input a telephone number or an e-mail address in accordance with an active application, but here, it is detected that the mobile device 100 has entered the communication area of the access point 51. In addition, the remote control function (remote control operation application) of the television 52 is automatically activated to become a push button for remote control operation (that is, the user interface has changed).

  Next, each function of the mobile device 100 will be described with reference to the functional block diagram of FIG. The mobile device 100 includes a control unit 120, a display unit (display device) 130, and a data storage unit 140. The control unit 120 further includes a radio network detection unit 121, a user interface selection unit 122, a function execution control unit 123, a telephone function processing unit 124, an information terminal function processing unit 125, and a radio signal transmission unit 126.

  As shown in the figure, the wireless network detection unit 121 includes, for example, a mobile phone network detection unit 121a and a wireless LAN detection unit 121b, and can detect two types of wireless networks, a mobile phone network and a wireless LAN. Here, the detection of the wireless network means that the mobile device 100 is in the communication area of the wireless network and can communicate with the wireless network. When a signal such as a beacon signal transmitted at an interval is received, or when a connection succeeds with a predetermined protocol after receiving the beacon signal, “detection” can be determined based on various criteria. Also, when the received signal strength reaches a predetermined level (this level may be different for each wireless network) or when a predetermined condition has continued for a certain period of time, it is determined that the signal has been “detected”. You may make it do.

  The wireless network detection unit 121 can include a detection unit corresponding to the type of wireless network to be detected. Even in the same wireless LAN, it is possible to recognize a network with a different SSID, VLAN-ID, access point (MAC address), etc. as another wireless network, and if that is sufficient, only the wireless LAN detection unit 121b is included. It can be constituted as follows.

  The user interface selection unit 122 selects a corresponding user interface according to the wireless network detected by the wireless network detection unit 121. The user interface is what kind of output the portable device 100 performs for the user (display) and what kind of processing is performed for the user input or other trigger (function). Therefore, in this example, the user interface is defined by setting information on the display surface and setting information on the functional surface.

  More specifically, a new user interface of the mobile device 100 is realized by referring to the user interface (UI) correspondence table 141 and the user interface (UI) definition table 142 stored in the data storage unit 140. The display setting file 143 and the function setting file 144 are acquired and set. The contents of the user interface correspondence table 141 and the user interface definition table 142 will be described in detail later.

  Here, when the setting information is composed of completely different sets, and these are used by switching, the user interface selection unit 122 can be understood as selecting “application” according to the detected wireless network.

  The function execution control unit 123 displays a predetermined display screen on the display unit 130 based on the display setting file 143 and the function setting file 144 selected and set by the user interface selection unit 122, and associates them with these display screens. Control execution of functions (applications) related to the selected user interface. As a result, it is configured in what form the mobile device 100 provides information to the user and which function is executed by which operation of the user (that is, a user interface is configured). The execution of the function may be triggered by a user operation or triggered by another event.

  The function execution control unit 123 also controls the execution of functions (applications) that do not use a wireless network that is detected as being communicable. For example, the remote control operation application and the music / video playback application illustrated in FIG. As described above, assuming that detection of a communicable wireless network only means a change in the situation or location, the application to be operated does not need to use the detected wireless network.

  The telephone function processing unit 124 realizes a telephone call via a mobile phone network or a wireless LAN under the control of the function execution control unit 123. The information terminal function processing unit 125 performs processing other than a call under the control of the function execution control unit 123. For example, processing related to the WEB browser function and the mail function is performed.

  The wireless signal transmission unit 126 realizes a remote control function that transmits a remote control signal to the television 52 under the control of the function execution control unit 123. This remote control signal is generally an infrared signal, and is transmitted to the infrared signal receiver of the television 52 by the infrared signal transmitter of the portable device 100. Further, when the television 52 is connected to the network 55, the television 52 can receive a remote control signal via another device or via a wireless LAN.

  As described above, in this example, the user interface is defined by the setting information on the display surface and the setting information on the function surface, and the function execution control unit 123 performs the functions related to the user interface based on the setting information. By executing, the selected user interface is realized, but a predetermined user interface can be realized by only setting information on the display surface, only setting information on the functional surface, or setting information from another viewpoint.

  Next, with reference to FIG. 3, the positional relationship between the mobile device 100 and the communication area of each wireless network is illustrated. FIG. 3A shows a situation in which the belonging communication area changes as the mobile device 100 that detects only the wireless network of the wireless LAN moves. Initially, the mobile device 100 is located in the communication area 151 formed by the access point 51a, but leaves the communication area 151 by movement and enters the communication area 152 formed by the access point 51b. Such a situation may occur, for example, when a user moves to another department or another floor within one company. Here, it is assumed that there are no overlapping communication areas.

  FIG. 3B shows a situation in which the belonging communication area changes as the mobile device 100 that detects the mobile phone network and the wireless LAN moves. Initially, the mobile device 100 is located in a communication area 161 of a relatively wide mobile phone network formed by the base station 20a, but the communication formed by the access point 51c and the access point 51d by movement. Enter the area 162 and the communication area 163. Then, when the mobile device 100 further moves, the communication area 162 and the communication area 163 are exited. Such a situation may occur, for example, when the user returns from the station to his home and then goes out.

  Next, the operation of the portable device 100 in the case of FIG. 3A will be described with reference to FIGS. FIG. 4A is a diagram illustrating an example of the user interface correspondence table 141. In the user interface correspondence table 141, a user interface ID is associated with a network ID. In this example, different user interface IDs are associated with different network IDs, but the same user interface ID may be associated with several network IDs. The network type item is given for convenience in order to indicate what network each network ID is.

  FIG. 4B is a diagram illustrating an example of the user interface definition table 142. The user interface definition table 142 stores a display setting file 143 and a function setting file 144 respectively corresponding to the user interface ID stored in the user interface correspondence table 141. The operation mode is given for convenience in order to indicate what function the user interface ID is. In this example, for the in-house wireless LAN 1 (network ID = N001), the mobile phone user interface (user interface ID = U001) for department X is used, and for the in-house wireless LAN 2 (network ID = N002) is used for department Y. A mobile phone user interface (user interface ID = U002) is associated.

  The display setting file 143 indicates a file used by the function execution control unit 123 (FIG. 2) in order to realize a user interface having a corresponding user interface ID. The display setting file 143 includes display contents and display position designation information for configuring a display screen for a user interface related to one function such as a remote control function, a mail function, and a WEB browser function. Not necessarily.

  Similarly to the display setting file 143, the function setting file 144 is a file used by the function execution control unit 123 (FIG. 2) in order to realize a user interface with a corresponding user interface ID. The function setting file 144 is a file that defines the processing contents of each function such as a remote control function and a mail function. The function setting file 144 also includes data used in the program such as address book data and menu data. With this configuration, for example, when moving from the communication area of the internal wireless LAN 1 (network ID = N001) of the X department to the communication area of the internal wireless LAN 2 (network ID = N002) of the Y department, the user interface ID Changes from U001 to U002, and the function setting file to be used is switched from F001 to F002. As a result, the address book data is switched from the X department to the Y department.

  In the example of FIG. 4B, each user interface ID is associated with a different display setting file 143 and function setting file 144, but the same display setting file 143 is associated with several user interface IDs. Further, the same function setting file 144 can be associated with different display setting files 143. In this example, a user interface related to one function is realized by controlling execution of functions related to the user interface using setting information such as the display setting file 143 and the function setting file 144. However, the scope of rights of the present invention is not limited to such a method. The user interface can be switched by configuring various other information as the setting information, such as switching the program to be called as setting information, switching the program argument as setting information, and switching this. .

  FIG. 5 is a flowchart showing the operation of the mobile device 100 in the case of FIG. 3A. The processing shown in FIG. 5 is repeatedly executed at short time intervals, so that when a change occurs in the network environment of the mobile device 100, this change can be detected immediately. In order to realize a long battery duration, the execution interval can be dynamically changed under a predetermined condition and controlled to be as long as possible.

  In step S10, the wireless network detection unit 121 of the mobile device 100 detects whether the mobile device 100 is in the communication area of the wireless network (whether communication is possible). More specifically, the mobile phone network detection unit 121a and the wireless LAN detection unit 121b receive and detect signals from the base station 20 and the access point 51. Therefore, when the mobile phone network detection unit 121a and the wireless LAN detection unit 121b determine that the mobile device 100 is in the communication area of the wireless network based on the various “detection” determination criteria described above (YES in step S12). ), Go to step S14.

  If the signal could not be received (NO in step S12), the process proceeds to step S24, in which setting is made so that “out of range” is displayed, which means that no wireless network is detected.

  In step S14, the network ID of the communicable wireless network is determined from the contents of the beacon signal. In step S16, the user interface ID (UI-ID) corresponding to the network ID is displayed in the user interface (UI) correspondence table. 141 by referring to FIG. For example, in the case of FIG. 3A, when the mobile device 100 is moving in the communication area 151, the network ID (= N001) is detected, and the corresponding user interface ID (= U001) is obtained accordingly. Thereafter, when the mobile device 100 enters the communication area 152, a network ID (= N002) is detected this time, and a corresponding user interface ID (= U002) is obtained accordingly.

  Next, in step S18, the user interface (UI) definition table 142 is referred to, and the display setting file 143 and the function setting file 144 corresponding to the obtained user interface ID are acquired. Thereafter, in step S <b> 20, the display screen is set to be output to the display device of the mobile device 100 according to the acquired display setting file 143. The display screen set in this way is output to the display device at a timing such as when the user turns on the power of the mobile device 100, starts an operation, or opens (folds the mobile phone). The

  Next, in step S22, when the user operates the portable device 100, the corresponding function is set to be executed according to the acquired function setting file 144. With this setting, when the user operates the mobile device 100, the function execution control unit 123 of the mobile device 100 detects this and performs control based on the set function setting file 144.

  In the case of FIG. 3A, when the mobile device 100 is moving in the communication area 151, the user interface ID (= U001) is obtained in step S16 (this user interface is a mobile phone for the department X). A display setting file (= D001) and a function setting file (= F001) corresponding to this are acquired. Here, the function setting file (= F001) includes, for example, the name of the department displayed on the standby screen. Further, an address book for department X (a list in which the extensions of employees in department X are displayed) is included, and this address book can be displayed by a user performing a predetermined operation.

  Thereafter, when the mobile device 100 enters the communication area 152, a user interface ID (= U002) is obtained in step S16 (this user interface is a mobile phone for the department Y), and a display setting file ( = D002) and a function setting file (= F002) are acquired. Here, the display setting file (= D002) includes, for example, the name of a department displayed on the standby screen. When the wireless network to which the mobile device 100 belongs changes, the name of this department also changes. In addition, the function setting file (= F002) includes, for example, an address book for department Y (a list in which the extensions of employees in department Y are displayed), and this address book is obtained when the user performs a predetermined operation. Can be displayed. As described above, the mobile device 100 can detect a change in the wireless network due to movement and automatically change its display and function.

  FIG. 6 is an example of a screen displayed on the display device of the mobile device 100 in the case of FIG. 3A. FIG. 6A shows a display screen 210 displayed when the mobile device 100 moves in the communication area 151. Here, a standby screen, that is, an IP phone standby screen in a mobile phone for department X is displayed. “Department X” is displayed in the lower right display portion 216, and it is possible to grasp which department's wireless network currently belongs to. When the mobile device 100 enters the communication area 152, the display setting file 143 is changed from D001 to D002 according to the procedure shown in the flowchart of FIG. 5, and as a result, “Department Y” is displayed in the lower right display portion 216. (Not shown).

  6B shows a display screen 220 when the mobile device 100 displays an address book while moving in the communication area 151. Here, since the mobile device 100 belongs to the in-house wireless LAN 1 of the department X, the address book is displayed. The display unit 224 displays a list of extensions of employees belonging to the department X. Such an address book is displayed when the user presses a predetermined push button of the mobile device 100 on the standby screen shown in FIG. 6A or the like.

  6C shows a display screen 230 when the mobile device 100 displays the address book after entering the communication area 152. Here, the mobile device 100 is connected to the internal wireless LAN 1 of the department Y from the internal wireless LAN 1 of the department X. Since it has moved to the LAN 2, the display content of the address book display unit 234 is switched from the address book of the department X to the address book of the department Y.

  Next, the operation of the mobile device 100 in the case of FIG. 3B will be described with reference to FIGS. FIG. 7A is a diagram showing another example of the user interface correspondence table 141. In this user interface correspondence table 141, the priority and duplication execution flag are associated with the network ID in addition to the user interface ID. The priority is a value that designates which wireless network is to be preferentially selected when the mobile device 100 belongs to a plurality of wireless networks. In this example, the lower the value, the higher the priority. . The duplicate execution flag indicates whether or not a certain function for realizing the corresponding user interface can be duplicated even if it is not selected due to low priority, and “1” can be duplicated. Represents something. The item of network type is given for convenience in order to indicate what network each network ID is.

  FIG. 7B has the same configuration as the example of the user interface definition table 142 shown in FIG. 4B. In this example, for the mobile phone network (network ID = N011), the user interface (user interface ID = U011) of the mobile phone is used. For the home wireless LAN 1 (network ID = N012), the user interface (user of the air conditioner remote control) is used. The interface ID = U012) and the home wireless LAN 2 (network ID = N013) are associated with the user interface (user interface ID = U013) of the television remote control.

  FIG. 8 is a flowchart showing the operation of the mobile device 100 in the case of FIG. 3B. The process shown in FIG. 8 is repeatedly executed at short time intervals in the same manner as the process shown in the flowchart of FIG. 5, so that when a change occurs in the network environment of the mobile device 100, this change is immediately detected. Can do.

  First, in step S40, the wireless network detection unit 121 of the mobile device 100 detects whether the mobile device 100 is in a wireless network communication area. More specifically, the mobile phone network detection unit 121a and the wireless LAN detection unit 121b receive and detect signals from the base station 20 and the access point 51. Therefore, when the mobile phone network detection unit 121a and the wireless LAN detection unit 121b receive a certain signal such as a beacon signal, it is determined in step S42 that the mobile phone network detection unit 121a and the wireless LAN detection unit 121b are within the communication area of the wireless network and are communicable (step S42). (YES in S42), the process proceeds to step S44.

  If the signal could not be received (NO in step S42), the process proceeds to step S60, in which setting is made so that “out of range” is displayed, which means that no wireless network is detected.

  In step S44, the network ID of a communicable wireless network is determined from the contents of the beacon signal and the like, and in step S46, the number of detected communicable wireless networks is determined. If it is determined that only one wireless network is detected at this timing, the process proceeds to step S52, where the user interface ID (UI-ID) corresponding to the network ID is stored in the user interface (UI) correspondence table 141. Seek by reference.

  If it is determined in step S46 that a plurality of wireless networks have been detected, the process proceeds to step S48, where the user interface correspondence table 141 is referenced, the priority order of those network IDs is acquired, and the highest priority is obtained. One user interface ID corresponding to the network ID is selected.

  Next, in step S50, the user interface correspondence table 141 is referred to for other network IDs, and it is checked whether or not the duplicate execution flag is “1”. When the duplicate execution flag is “1”, the user interface ID corresponding to the network ID is selected as an execution target.

  The processing from step S54 to step S58 is the same as that from step S18 to step S22 shown in FIG. However, with respect to the user interface ID selected to be executed repeatedly in step S50, for example, only a predetermined function that is activated by an event other than an operation by the user is executed in the background.

  FIG. 9 is an example of a screen displayed on the display device of the mobile device 100 in the case of FIG. 3B. FIG. 9A shows a display screen 310 displayed when the mobile device 100 is moving in the communication area 161 of the mobile phone network. Here, a standby screen, that is, a mobile phone standby screen is displayed.

  FIG. 9B is displayed when the mobile device 100 is in a position where three communication areas (communication area 161 (mobile phone network), communication area 162 (home wireless LAN 1), and communication area 163 (home wireless LAN 2)) overlap. The display screen 320 is displayed. Although the mobile device 100 belongs to three communication areas, a user interface corresponding to the home wireless LAN 2 (user interface ID = U013) having the highest priority, that is, a television, is obtained by the processing shown in the flowchart of FIG. John's remote control is realized. In the display screen 320 shown in FIG. 9B, “TV remote control” is displayed on the upper title display portion 322, and “Please push the push button when changing the channel” is displayed on the lower guide display portion 324. Is done. When the user presses a push button such as “6” in this state, the function execution control unit 123 of the portable device 100 generates a signal for changing the channel of the television 52 to “6” in response to this operation.
