Description

  The present invention relates to a control method for a terminal device, a radio communication system, a terminal device, a control program, and a recording medium, and in particular, applied to control of a terminal device that is connected to a base station device on a network by wireless communication and executes a program. It is related to effective technology.

  Conventionally, in a communication system that connects a portable terminal device such as a notebook PC (Personal Computer) or PDA (Personal Digital Assistance) to a network, a wireless communication is performed between the terminal device and a base station device belonging to the network. There are wireless communication systems that perform communication.

  In the wireless communication system, in order to improve the convenience of the user of the terminal device, a method for automatically controlling connection of the wireless connection between the terminal device and the base station device, or a change in the communication state triggers the terminal device. A method for controlling the execution of the program is considered.

  As a method of automatically performing connection control of the wireless connection, for example, when a terminal device searches for and detects a base station device, a profile corresponding to a network to which the detected base station device belongs is a terminal device. A method has been proposed in which a new registration is made if it is not registered, and a connection is made according to the profile if it is registered (see, for example, Patent Document 1).

  In the connection control method described in Patent Document 1, one corresponding profile is automatically registered for each network. The network is switched, for example, in response to a change in the surrounding environment such as a change in the routing table. That is, the connection control method described in Patent Document 1 is based on the premise that the network is automatically switched by a passive procedure. Further, in the connection control method described in Patent Document 1, it is considered that the program is automatically executed after the connected network (base station device) is switched.

  On the other hand, as a method for performing program execution control in the terminal device, for example, when the terminal device is activated, the terminal device automatically receives content distributed from a server on the network. Has been proposed (see, for example, Patent Document 2).

However, the program execution control method described in Patent Document 2 does not target priority control considering a plurality of connection destinations, and does not consider changing the program to be executed according to the connection destinations. .

  In the wireless communication system, by applying the control method described in Patent Literature 1 or Patent Literature 2, connection control to a network (base station device) and program execution control can be performed. It is thought that the convenience of the user will increase.

However, in the control methods described in Patent Document 1 and Patent Document 2, for example, the following requirements (1-1), (1-2), and (1-3) It is not possible to respond to (conditions).
(1-1) Connect to the base station apparatus of the first network and execute the program A.
(1-2) Connect to the base station apparatus of the second network and execute the program B.
(1-3) When both the base station apparatus of the first network and the base station apparatus of the second network 2 are detected, the steps are sequentially performed with the priorities of (1-1) and (1-2).

  In order to satisfy the first requirement, it is necessary to detect when the program A executed by connecting to the first network is terminated. However, the control methods described in Patent Document 1 and Patent Document 2 do not have a function of detecting the end of an arbitrary program. Therefore, the wireless communication system to which the control method described in Patent Document 1 or Patent Document 2 is applied cannot perform control that satisfies the first requirement.

  Further, even if the end of the program A can be detected, in order to satisfy the first requirement condition, after detecting the end of the program A, from the state connected to the first network (base station apparatus) It is necessary to actively disconnect the first network and switch the connection to the second network (base station apparatus). However, the control methods described in Patent Document 1 and Patent Document 2 do not have a function of actively switching connection to a specific network in a state where base station devices belonging to a plurality of different networks are detected. That is, in the wireless communication system to which the control method described in Patent Document 1 or Patent Document 2 is applied, for example, the network connection must be manually switched. Therefore, the wireless communication system to which the control method described in Patent Document 1 or Patent Document 2 is applied cannot perform control that satisfies the first requirement.

Further, in a wireless communication system to which the control method described in Patent Document 1 or Patent Document 2 is applied, the following requirements (2-1), (2-2), and (2-3) (Also referred to as the second requirement).
(2-1) Connect to the base station apparatus of the first network with user ID = aaa and execute the program A.
(2-2) Similarly, connect to the base station apparatus of the first network with user ID = bbb and execute the program B.
(2-3) When the base station apparatus of the first network is detected, it is sequentially performed with the priorities of (2-1) and (2-2).

  The second requirement condition corresponds to a case where normal connection and roaming connection in the public wireless LAN service are sequentially performed.

  In order to satisfy the second requirement condition, after connecting to the base station apparatus of the first network with user ID = aaa and executing program A, the user ID is actively switched from aaa to bbb again. It is necessary to reconnect. However, in the control methods described in Patent Literature 1 and Patent Literature 2, after connecting to a base station device of a certain network and executing a program, the user ID is actively switched to re-enter the base station device of the same network. It is not assumed to be connected. Therefore, in the radio communication system to which the control method described in Patent Document 1 or Patent Document 2 is applied, the second requirement condition cannot be realized.

Further, in a wireless communication system to which the control method described in Patent Document 1 or Patent Document 2 is applied, the following requirements (3-1), (3-2), and (3-3) It is not possible to cope with the third requirement).
(3-1) Connect to the base station apparatus of either the first network or the second network and execute the program A.
(3-2) Program A is executed at a frequency of 30 minutes or more.
(3-3) When 30 minutes have not elapsed since the previous execution of the program, it is not necessary to execute the program, and therefore connection to the base station apparatus is not performed even if the base station apparatus is detected. However, if the wireless connection is disconnected during the program execution and the data transmission / reception processing is incomplete, a retry is made immediately instead of every 30 minutes.

  In a wireless communication system to which the control methods described in Patent Document 1 and Patent Document 2 are applied, as an example of a case where the third requirement condition cannot be satisfied, the wireless communication system is connected to a base station apparatus of the first network. After executing the program A, it is assumed that the user who has the terminal apparatus moves to an area where wireless communication with the base station apparatus of the second network 2 is possible within 30 minutes. At this time, the terminal apparatus detects the base station apparatus of the second network within 30 minutes after executing the program A in the first network.

  At this time, the execution interval of the program A in the terminal device is 30 minutes or more and there is no other program to be executed. Therefore, it is not necessary to connect to the base station device of the second network. However, in the control methods described in Patent Document 1 and Patent Document 2, it is connected to the base station apparatus of the second network only because it is a registered network, and power is wasted. It will be. In order to prevent such unnecessary connection, it is necessary to associate the execution history of the program with connection control.

  As described above, in a wireless communication system to which the control method described in Patent Literature 1 or Patent Literature 2 is applied, connection control that actively switches the connection between the terminal device and the base station device cannot be performed. Therefore, for example, there is a problem that it is impossible to cope with complicated requirement conditions such as the first and second requirement conditions.

  An object of the present invention is to provide a technique capable of actively switching a connection between a terminal apparatus and a base station apparatus and efficiently executing a plurality of programs.

  Another object of the present invention is to provide a technique capable of preventing wasteful connection between a terminal device and a base station device and reducing waste of power of the terminal device.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  The outline of the invention disclosed in the present application will be described as follows.

(1) It is possible to connect to a network by performing wireless communication between at least one network including a base station device for wireless communication and the base station device, and execute a predetermined program In a wireless communication system comprising a terminal device, a terminal device control method for controlling wireless connection between the terminal device and the base station device and controlling execution of the program, the base station connected to the terminal device A step of registering a profile including an apparatus network ID and execution information of a program to be executed after connection by specifying a priority, and the terminal apparatus is received by the terminal apparatus by an external start trigger compared with the network ID by the base station apparatus notifies, and a network ID registered in the terminal device, connectable base station device Determining whether, when there is the connectable base station device, connected to the base station apparatus in accordance with the priority among the profile including the network ID which is informed from the base station apparatus, executes the program And a step of controlling the terminal device.

  (2) In (1), the start trigger from the outside is an input from a man-machine interface or a power-on of the terminal device.

(3) In the above (1) or (2), the step of registering the profile, as the execution information of the program, one or more programs, and the execution order of the program, and registers the execution timing of each program The step of connecting to the base station apparatus and executing the program includes the step of determining whether or not each program needs to be executed according to the execution order of the programs, and is determined to be required to be executed. If it is determined that there is no need to execute the program, the program proceeds to the next process without executing the program.

  (4) In step (3), the step of connecting to the base station apparatus and executing the program includes executing whether each program is executed normally and whether or not the program has ended normally and an end status including an end time. As a saving step.

  (5) In the above (4), the step of determining whether or not the program needs to be executed is when the execution timing of the program is immediately after connection or every time it is connected, or when the execution timing is a predetermined time interval And the program corresponding to either the case where the time interval has elapsed from the end time of the end status or the case where the end status indicates abnormal end is determined to be executed. .

  (6) In the above (5), when the same program is specified in a plurality of profiles, the step of determining whether or not the program needs to be executed is the latest among the end statuses of the profiles. Judgment is made using the end status.

  (7) In any one of (4) to (6), the step of connecting to the base station apparatus and executing the program executes the program included in the profile before connecting to the base station apparatus. When there is no program that needs to be determined by determining whether it is necessary, connection to the base station apparatus is not performed.

(8) In any one of (1) to (7), in addition to the above steps, whether or not to turn off the power of the terminal device after executing all profiles in the terminal device, and the terminal When registering whether or not to automatically execute processing when the device is started, and registering when the power is turned off, when no base station device that can be connected is detected for all profiles If the terminal device is turned off and registered to automatically execute processing when the terminal device is activated, the terminal device is turned on and then connected to the base station device. The step of executing is restarted from the initial processing.

  In the method for controlling a terminal device according to the present invention, as in the means (1) to (6), the terminal device has a plurality of profiles including a network ID for each base station device and program information executed after connection. In each profile, a plurality of pieces of program information to be executed are registered. At this time, a priority is designated for the profile. The terminal device then connects to the base station device and executes the program according to information such as the start timing of the program specified in the profile, the priority of the profile, and switches the connection to another base station device. Perform the operation. Therefore, for example, it is possible to actively (automatically) perform complex processing such as switching connection to different base station devices, reconnecting to the same connection device with different authentication information, and switching connections after the program ends. And the convenience of the user of the terminal device is improved.

  Further, in the method for controlling a terminal device according to the present invention, when a base station device connectable by the terminal device is detected as in the means (7), a program registered in a profile related to the base station device is executed. It is determined whether or not it is necessary, and if there is no program that needs to be executed, the base station apparatus is not connected. Therefore, useless connection to a base station apparatus and execution of a program as in a conventional wireless communication system are eliminated, and power consumption of the terminal apparatus can be reduced.

  Furthermore, if the means (8) is used, the terminal device can be automatically turned off after the profile processing is completed, and the program execution (profile processing) becomes necessary again. When the power is turned on, the terminal device can again connect to the base station device and execute the program from the beginning. Therefore, it is possible to prevent standby power consumption of the terminal device while the program is not executed.

  Further, in the wireless communication system, in order to realize the terminal device control method such as the means (1) to (8), for example, the network ID of the base station device connected to the terminal device, and the connection Connection is made by comparing a profile holding means for holding one or more profiles including execution information of a program to be executed later by specifying a priority, and a network ID notified by the base station apparatus and a network ID of the profile Determining whether there is a base station apparatus that can be connected, and when there is a connectable base station apparatus, connection control means for performing connection processing with the base station apparatus according to the priority of the profile, and the connectable base After connecting to the station apparatus, the program control method detects the program execution control and the program end based on the profile. If, on the basis of the profile held in the profile holding means, management of the respective control means, priority control of profiling, may be provided and overall control means for performing schedule management.

  At this time, for example, the program control means is provided with means for determining whether or not there is a program that needs to be executed based on the execution information of the program of the profile after connecting to the connectable base station apparatus. If only the programs that need to be executed are executed, wasteful program execution processing is eliminated and power consumption can be reduced. Further, for example, before performing connection processing with the connectable base station apparatus, the connection control unit needs to connect to the base station apparatus and execute it based on execution information of the profile program. When there is no program that needs to be executed and a program for determining the presence / absence of a program is provided, if the connection process to the base station apparatus is not performed, the wasteful connection process is eliminated and the waste of power can be further reduced. . Furthermore, in addition to the above means, the terminal device is provided with power supply control means for detecting power ON of the terminal device and turning off the terminal device when there is no connectable base station device. In this case, the control like the means (8) can be performed, and standby power consumption can be prevented.

  In addition, the terminal device, for example, causes a portable computer such as a notebook PC or PDA having a wireless LAN function and the computer to execute a control method such as the means (1) to (8). It can also be realized by a control program.

  At this time, the control program can be provided, for example, by being recorded on a magnetic, electrical, or optical recording medium in a state that can be read by the computer, for example, a network such as the Internet. Can also be provided.

Hereinafter, the present invention will be described in detail together with embodiments (examples) with reference to the drawings.
In all the drawings for explaining the embodiments, parts having the same function are given the same reference numerals and their repeated explanation is omitted.

  In the terminal device control method of the present invention, the terminal device has a plurality of profiles including connection processing and authentication information for each base station, and each profile stores a plurality of program information to be executed. Each profile is assigned a priority. At this time, the terminal device operates according to information such as the program start timing and the priority order between profiles. For example, when the same program is registered in a plurality of profiles, there is no program to be executed. For example, avoid unnecessary operations.

In FIG. 1, 1 is a terminal device, 2A is a first network, 201A is a base station device (wireless base station) belonging to the first network, 202A is a server belonging to the first network, 2B is a second network, and 201B is a second network. A base station apparatus (radio base station) 202B belonging to the network is a server belonging to the second network. In FIG. 2, 101 is hardware, 102 is an OS, 103 is a program to be executed after connection, 104 is a control program (middleware), 105 is profile holding means, and 106 is history holding means.

  As shown in FIG. 1, the wireless communication system according to the present embodiment includes a terminal device 1 capable of wireless communication and two networks 2A and 2B including a base station device to which the terminal device 1 can be connected. . In this embodiment, in order to simplify the description, the case where there are two networks of the first network 2A and the second network 2B is taken as an example. There may be a network.

  In the wireless communication system of the present embodiment, for example, the terminal device 1 establishes a connection by wireless communication with the base station device 201A of the first network 2A, and then, via the base station device 201A, It is assumed that the program can be executed by connecting to the server 202A of the first network. Similarly, after the terminal device 1 establishes a connection with the base station device 201B of the second network 2B by wireless communication, for example, the server of the second network 2B passes through the base station device 201B. Assume that it is possible to connect to 202B and execute a program.

  The terminal device 1 is a device (computer) such as a notebook PC or PDA having a wireless communication function such as a wireless LAN, and controls and programs for connection to the base station devices 201A and 201B Is controlled by a control program (software) executed on the terminal device 1. Hereinafter, the control program is referred to as middleware in order to distinguish the control program from a program executed after connecting to the base station apparatuses 201A and 201B.

  At this time, the functional block diagram of the software in the terminal device 1 includes, for example, hardware 101 and an operating system (OS) 102, a program 103 executed after connection, and the middleware 104 as shown in FIG. Here, the OS 102 has a function of directly controlling the hardware 101. For example, as shown in FIG. 2, the OS 102 controls the operation of a power control unit that controls ON / OFF of a power switch and wireless communication means. It has a communication control part to control.

  Further, the middleware 104 that implements the control method of the present invention, for example, compares the network ID reported by the base station device with the network ID of the profile to determine whether there is a connectable base station device, and to connect A connection control function for performing connection processing with the base station device according to the priority of the profile when there is a base station device capable of being connected, and a program based on the profile after connecting to the connectable base station device Execution control, and program control function for detecting the end of the program, detection of power ON of the terminal device, and power control function for turning off the power of the terminal device when there is no connectable base station device; Based on the profile held in the profile holding means, management of each control means and profile processing Previous control, and an overall control function of performing schedule management. At this time, the overall control function also has a function of reading a profile of the profile holding unit 105, saving / reading an end status (execution history) to the history holding unit 106, and the like.

  Further, the program control function may include a function of determining whether there is a program that needs to be executed based on execution information of the program of the profile after connecting to the connectable base station apparatus, for example. Good.

  Further, the connection control function needs to be executed by connecting to the base station apparatus based on execution information of the profile program, for example, before performing connection processing with the connectable base station apparatus. A function for determining the presence or absence of a program may be provided.

  The profile held by the profile holding means 105 includes, for example, as shown in FIG. 3, the priority of the profile, the identification information (network ID) of the network to be connected, and the network for authenticating the connection of the terminal device. It has authentication information and program execution information such as the type of program to be executed when the terminal device is connected to the network and the execution interval. Then, the middleware 104 of the terminal device 1 performs connection processing and program execution processing according to the contents of the profiles in order from the profile with the highest priority.

  Hereinafter, a terminal device control method in the wireless communication system configured as shown in FIGS. 1 to 3 will be described.

  4 to 7 are diagrams illustrating an example of a profile setting method in the terminal device of the wireless communication system according to the present embodiment. FIG. 4 is a diagram illustrating an example of a profile setting screen. FIG. FIG. 6 is a diagram illustrating an example of a screen for setting an execution frequency, FIG. 6 is a diagram illustrating an example of a screen for setting a network (base station device) to be connected, and FIG. 7 is an example of a screen for setting authentication information, an authentication method, and the like. FIG.

  In the wireless communication system of the present embodiment, first, for example, a profile as shown in FIG. 3 is set in the terminal device. When the profile is set by the terminal device, for example, a screen W1 as shown in FIG. 4 is displayed on the display means (display), and the user sets each item using the input means. In the example shown in FIG. 4, the SSID and status are displayed for each profile. In addition, it is possible to specify whether or not to perform connection processing for each profile with a check box on the left side of each profile name. The priority order of each profile can be specified by selecting the profile and moving it up and down with the “▲” and “▼” buttons.

  In addition, when a “New” button is pressed on the screen W1 shown in FIG. 4, a new profile setting screen is opened, and a new profile can be created. It is also possible to modify the profile by selecting an existing profile and pressing the “Edit” button. You can also delete a profile with the “Delete” button.

  Further, when the “Connect” button is pressed on the screen W1 shown in FIG. 4, connection processing is simply performed with the highest priority profile, the program is not executed, and the connection state is maintained. When the “Disconnect” button is pressed, the connection is disconnected or the connection process is canceled. As soon as the “Connect / App Execute” button is pressed, connection processing / automatic program execution is executed sequentially from the high priority profile. Note that you can specify whether to automatically suspend (power off) after executing all profiles using the check box at the bottom of the screen. When the “Execute Suspend / App” button is pressed, the terminal device is suspended immediately after. Next, when the terminal device is activated, the connection processing / automatic program execution is automatically executed sequentially from the high priority profile, and the suspension is suspended again.

  Here, an automatic activation by an external device can be considered as a trigger for activating the terminal device after suspending by pressing the “suspend / app execution” button. For example, an external device that can detect the wireless LAN radio wave and automatically turn on the terminal device when entering the wireless LAN service area. This makes it possible to automatically execute necessary programs in the terminal device and automatically turn off the power when the user enters the service area without operating the terminal device, reducing power consumption. Is done.

  When the “Connect / App Execute” button and “Suspend / App Execute” button are pressed, a new screen showing the automatic execution status of the program is opened. It is also possible to stop the execution and return to the screen W1 in FIG.

  Further, when the “new” or “edit” button is pressed on the screen W1 as shown in FIG. 4, for example, the display is switched to a screen for performing detailed setting of the profile. The detailed setting screen is composed of, for example, three screens. First, a program setting screen W2a as shown in FIG. 5 is displayed. On the screen W2a shown in FIG. 5, program execution information is set, for example, from the top of the screen in order from the program with the highest priority. In this setting, for each program, whether or not there is an execution reservation is specified by a check box, and the execution frequency of each program can be specified. If “every time” is specified here, it means that the program is always executed immediately after connection. “Once” executes the program only once, and otherwise designates the program execution interval.

  Here, when the same program is specified with different profiles, the following processing is performed. For example, program A is registered in profile 1 and the frequency is set at an interval of 30 minutes. At this time, when the program A is also registered in the profile 2, the frequency is automatically linked to the profile 1 and becomes an interval of 30 minutes. At this time, the user's requirement is that the program A can be executed by either profile 1 or profile 2. That is, even if the program A is executed with the profile 1 and then connected with the profile 2, the program A is not executed unless 30 minutes have passed. When it is desired to execute the program A sequentially with both profiles, it is necessary to set the frequency to “every time”.

  When the program execution information is set and, for example, the “NW” tab at the lower end of the screen W2a shown in FIG. 5 is pressed, the screen switches to the NW setting screen W2b as shown in FIG. On this screen, various network-related parameters such as SSID are set. As for the SSID, as shown in FIG. 4, it is possible to set the same SSID with different profiles. At this time, when the “app” tab at the lower end of the screen W2b shown in FIG. 6 is pressed, the screen returns to the screen W2a as shown in FIG.

  When the program execution information is set and the NW is set, for example, when the “authentication” tab at the lower end of the screen W2b shown in FIG. 6 is pressed, the screen is switched to the authentication setting screen W2c as shown in FIG. On this screen W2c, authentication information such as an ID / password is set. At this time, when the “app” tab at the lower end of the screen W2c shown in FIG. 7 is pressed, the screen returns to the screen W2a as shown in FIG. 5, and when the “NW” tab is pressed, the screen shown in FIG. Return to the screen W2b.

  Then, each item is set in accordance with the instructions on the screens W2a, W2b, and W2c in FIGS. 5 to 7, and a button indicating “OK (close)” displayed on the upper right of each screen is pressed to create a profile. / Editing is completed, and the screen returns to the screen W1 as shown in FIG. 4, for example.

  The terminal device 1 according to the present embodiment can perform an authentication process with different authentication information for one SSID and automatically execute different programs with the profile configuration registered in the above procedure.

  FIG. 8 is a flowchart showing a procedure of connection processing and program execution processing in the terminal device of the wireless communication system of the present embodiment.

  When the terminal device 1 whose profile is registered in accordance with the setting screen as shown in FIG. 4 to FIG. 7 is used for wireless connection with the base station device belonging to the network and the program is executed, first, as shown in FIG. Next, a neighboring base station device is searched (step 301). The step 301 is performed by the overall processing function and connection control function of the middleware 104 shown in FIG. 2, the communication control unit of the OS 102, and the wireless communication means of the hardware 101. When a base station device is detected, it is checked against a registered profile, and whether or not the terminal device 1 is a connectable base station device, in other words, a base station device of an SSID included in the registered profile. A determination is made (step 302). At this time, if no connectable base station apparatus is detected, the process ends as shown in FIG.

  On the other hand, when a base station apparatus to which the terminal apparatus 1 can be connected is detected, connection processing is performed along the profile having the corresponding SSID (step 303). At this time, if there are a plurality of corresponding profiles, the priorities of the profiles are compared, and connection processing is performed in order from the profile with the highest priority.

  In the connection process in step 303, first, a wireless connection is established and an authentication process is executed. Then, it is confirmed whether the connection establishment and authentication processing is successful (step 304). If the connection establishment or authentication process fails at this time, for example, as shown in FIG. 8, the process returns to step 301 to perform the connection process for the next profile. In the example shown in FIG. 8, the process returns to step 301, but not limited to this, the process may return to step 303.

  On the other hand, when the connection establishment and authentication processing is successful, the programs registered in the profile are sequentially executed in the designated order. First, it is determined whether or not each program needs to be executed (steps 305 and 306). In step 305 and step 306, if the end status at the previous execution is abnormal, or the specified timing is to be executed every time immediately after connection, or if the specified time has passed since the previous end, Consider execution necessary. Then, the program determined to be necessary is executed (step 307). After execution, the distinction between normal end / abnormal end is stored as an end status. Also, the end date and time is stored. Here, if the process ends abnormally, the end date / time is not updated.

  When the program executed in step 307 ends and the end status is stored, the process returns to step 305 and step 306 to determine whether there is another program that needs to be executed and there is a program that needs to be executed. If so, execute sequentially.

  Thus, when the determination / execution of all the programs registered in the profile is completed, the process proceeds to the next profile process as shown in FIG. 8, for example. If the processing is completed for all profiles, that is, if no connectable base station is detected, the processing ends.

  By performing connection processing and program execution processing according to the profile in the above procedure, when there are a plurality of profiles to be processed, connection processing and active (automatic) according to the priority of each profile. Program execution processing is possible.

  In addition, after connecting to the base station apparatus, only the program determined to be executed in Steps 305 and 306 is executed, so that it is possible to reduce the waste of power due to the execution of the useless program as in the prior art. Can do.

  FIG. 9 is a flowchart illustrating a first application example of the procedure of the connection process and the program execution process in the terminal device of the wireless communication system according to the present embodiment.

  When the connection process of the terminal device 1 and the program execution process are performed according to the procedure shown in FIG. 8, a program that does not need to be executed at the time of connection is not executed, and therefore unnecessary operations in the program execution process are omitted. be able to. However, if it is determined that not all programs need to be executed, a wasteful operation of performing wireless connection to the base station apparatus occurs even though there is no program to be executed, and wasteful power is wasted. Is done.

  Therefore, when connection processing and program execution processing are performed in the terminal device 1, as shown in FIG. 9, before performing the connection processing in step 303, it is confirmed whether there is a program that needs to be executed (step 308). It is preferable. In FIG. 9, steps 301 to 307 are the same as steps 301 to 307 shown in FIG.

  Step 308 is the same as the determination processing in steps 305 and 306, and it is determined whether or not there is one or more programs that need to be executed at the present time. That is, the end status at the previous execution is abnormal. If there is, or the specified timing is to be executed every time immediately after connection, or if there is even one program that has passed the specified time since the previous end, connection processing is performed, but execution is required immediately If there is no such program, the connection processing is not performed and the next profile is processed.

  As described above, before connecting to the base station apparatus, the presence / absence of a program to be executed is confirmed, and only when there is a program that needs to be executed, the connection process (step 303) and subsequent processes are executed. Even when there is no program, the useless operation of performing the connection process can be prevented, and the waste of power can be further reduced.

  FIG. 10 is a flowchart illustrating a second application example of the procedure of the connection process and the program execution process in the terminal device of the wireless communication system according to the present embodiment.

  When the terminal device 1 connection process and the program execution process are performed according to the procedure shown in FIG. 8 or FIG. 9, the unnecessary program execution process and the connection process to the base station apparatus are not performed. Waste is reduced. However, in the processing procedure as shown in FIG. 8 or FIG. 9, the power is turned on and nothing is continued after the processing is completed, so that power is wasted.

  Therefore, when performing connection processing and program execution processing in the terminal device 1, for example, as shown in FIG. 10, if no connectable base station device is detected in step 302, the power is turned off (step 309) is preferable. In step 302, in addition to the case where the base station apparatus itself is not detected, it is assumed that the base station apparatus is not detected when the processing of all the profiles related to the detected base station apparatus is completed. In FIG. 10, steps 301 to 308 perform the same processing as steps 301 to 308 shown in FIG. 9, and thus the processing content of each step is omitted.

  At this time, in step 309, instead of turning off the power completely, a state called standby or suspend may be set. In this case, when the power is turned on after shifting to the standby or suspend state (step 310), the process is resumed from the beginning (step 301) as shown in FIG. It is also possible. In this way, it is possible to repeat the same operation after turning on (returning) the power while reducing waste of power due to a wasteful operation during standby until the next program execution time.

  Next, specific examples and operational effects of the terminal device control method according to the processing procedure shown in FIGS. 8 to 10 will be described.

  FIGS. 11 to 13 are schematic diagrams for explaining application examples and operational effects of the wireless communication system of this embodiment. FIGS. 11 and 12 execute two programs by switching the connection to the base station apparatus. FIG. 13 is a diagram illustrating the operation when two programs are executed by switching the connection with one base station apparatus.

As an example of the operational effect when the radio communication system of the present embodiment is applied, first, the following requirement conditions (1-1), (1-2), and (1-3) (first requirement conditions) The control will be described.
(1-1) Connect to the base station apparatus of the first network and execute the program A.
(1-2) Connect to the base station apparatus of the second network and execute the program B.
(1-3) When both the base station apparatus of the first network and the base station apparatus of the second network 2 are detected, the steps are sequentially performed with the priorities of (1-1) and (1-2).

  In the wireless communication system according to the present embodiment, when the first requirement condition is to be satisfied, the terminal device 1 includes, for example, an SSID of the base station device 201A of the first network 2A as shown in FIG. Profile 1 with parameters (authentication information) and program execution information (program A) set, SSID of base station apparatus 201B of the second network 2B, related parameters (authentication information), and program execution information (program B) Register profile 2 in advance. At this time, the priority of the profile 1 is set to 1, and the priority of the profile 2 is set to 2.

  At this time, in the terminal device 1, when the base station device 201A of the first network 2A and the base station device 201B of the second network 2B are detected as connectable base station devices, the corresponding profiles 1 And Profile 2 is executed. At this time, since the priority of the profile 1 is high, the terminal device 1 first performs connection processing with the base station device 201A of the first network 2A along the profile 1 as shown in FIG. And execute program A.

  When the program A ends, the terminal device 1 returns to the initial processing (step 301), for example, as shown in FIG. 8, and the base station device of the first network 2A is connected as a connectable base station device. The station apparatus 201A and the base station apparatus 201B of the second network 2B are detected again. However, since the terminal device 1 is already connected to the base station device 201A of the first network 2A and the processing of the profile 1 is already completed, this time, as shown in FIG. The connection process of profile 2 related to the base station apparatus 201B of the second network 2B is performed, and the program B is executed.

  In the wireless communication system of the present embodiment, switching of the connection from the base station apparatus 201A of the first network 2A to the base station apparatus 201B of the second network 2B is actively triggered when the program A ends. (Automatically). Therefore, unlike the methods described in the conventional patent documents 1 and 2, it is not necessary for the user to confirm the end of the program A and manually switch the connection destination. As a result, user convenience is improved.

  Further, the radio communication system according to the present embodiment is also applicable to a case where setting is made to enable roaming connection between the first network 2A and the second network 2B, for example, as shown in FIG. is there.

  In the conventional wireless communication system described in Patent Document 1, for example, one profile is created for each SSID (base station apparatus), and one profile is automatically generated from base stations detected in the surroundings. The connection processing is performed according to the selected profile, the program is automatically executed, and the processing ends there. Therefore, for example, even when the roaming connection as shown in FIG. 13 is possible, when the program B is executed by connecting to the second network 2B, the base station apparatus 201B belonging to the second network 2B is connected. I had to fix it.

  On the other hand, in the wireless communication system of the present embodiment, a plurality of profiles can be defined for one SSID in consideration of roaming. That is, for example, as shown in FIG. 13, in the profile 2 of the program B executed by being connected to the second network 2B, the SSID of the base station device 201A of the first network 2A and the authentication information for the second network 2B ( Related parameters) can be set. In this way, the connection process to the base station apparatus 201A of the first network 2A is performed with the profile 1, and immediately after the program A is executed, the base of the first network 2A using the different authentication information with the profile 2 It is possible to execute a different program B by making a roaming connection to the second network 2B via the station device 201A.

  As described above, according to the wireless communication system of the present embodiment, by making the configuration of the profile indicating the attribute of the connection process in the terminal device flexible, for each network ID broadcast from the base station device, Therefore, it becomes possible to handle complicated requirements such as connection processing with different authentication information and execution of different programs. Also, by efficiently performing connection processing of a plurality of profiles and automatic execution of a program, it is possible to improve user convenience and reduce power consumption by automating the processing.
