Description

  The present invention relates to an information processing apparatus and an information processing program.

  In companies and the like, a wireless local area network (LAN) is often used as a connection between a host computer and a plurality of terminals. In such a wireless LAN environment, the wireless area is divided into a plurality of cells. One cell is a wireless area that can be covered by one access point. Within one cell, the number of terminals that can occupy an access point at the same time is limited to one.

  When a plurality of terminals are installed in the wireless LAN environment, the plurality of terminals share a cell. On the other hand, in a company or the like, for example, at a business start time, a business application downloads a large amount of data all at once in order to acquire data used for the business and update security patches and virus patterns. For example, the virus pattern download is executed at approximately the same time every day on business by all terminals related to the business. Therefore, it is required to efficiently download data while avoiding communication collision between a plurality of terminals in the same cell.

Priority is given to the access points, and the access points are connected to the access points in descending order of the received radio wave strength using the priority table. It has been proposed to generate a cryptographic key by combining with a lower-order character code of the MAC address of a part and notify the connection requesting wireless LAN station.

  Further, in a wireless LAN system in which wireless communication between a plurality of computers is performed via a relay device, the relay device is preset with an upper limit value of the number of computers that can be relayed. It has been proposed to refuse to relay wireless communications.

  Each of the mobile communication terminals receives an update notification including an icon start time for displaying and starting the update notification icon, which is set to be distributed over time, from the distribution server, and the time at the mobile communication terminal However, the update notification icon is displayed and activated when the icon activation time set for its own mobile communication terminal is reached, so that each mobile communication terminal has the icon activation time set to be dispersed in time. A means has been proposed in which an update notification icon is displayed and activated, modified software is downloaded in accordance with an instruction from a user who has recognized the icon, and software update is performed.

  FIG. 13 is an explanatory diagram of a connection status from a terminal to an access point in a wireless LAN system.

  A plurality of terminals # 1 'to # 3' in the same cell often have different communication speeds. For example, after a collision occurs between terminals # 2 ′ to # 3 ′ or between terminals # 1 ′ to # 2 ′ as indicated by “x”, terminal # 1 ′ having a high communication speed executes a download.

  Thereafter, the terminal # 3 'having a low communication speed executes the download. Since the communication speed of the terminal # 1 'is low, the occupied time T # 301 in which the terminal # 1' occupies the cell or the access point is long even if the wireless LAN communication speed itself is high. For this reason, while the terminal # 3 ′ is executing the download, the other terminal # 2 ′ in the same cell may wait for access to the network because the cell is occupied and end the download. Cannot start business.

  FIG. 1 is an example of the configuration of a wireless LAN system.

  The wireless LAN system includes a plurality of terminals 1 and one wireless LAN station 2. A cell 3 is defined by the wireless LAN station 2. In other words, the cell 3 corresponds to the wireless LAN station 2.

  The terminal 1 is an information processing apparatus that can access the wireless LAN station 2 and includes, for example, a mobile computer and a portable terminal. When accessing the network, the terminal 1 makes a connection request to the wireless LAN station 2 that is an access point. Thus, the terminal 1 is connected to the host computer via the network and communicates with the host computer.

  The wireless LAN station 2 is an access point in the cell 3. The wireless LAN station 2 relays communication to an external network through wireless communication with the terminal 1. In one cell 3, one terminal 1 can communicate with the wireless LAN station 2 at the same time. When a plurality of terminals 1 are distinguished, they are represented as terminal # 1, terminal # 2, terminal # 3,..., Terminal #n (n is an integer).

  For example, the reception strength of the received radio wave from the wireless LAN station 2 in the terminal # 1 is represented as “X # 1”, and the communication speed between the terminal # 1 and the wireless LAN station 2 is represented as “V # 1”. The same applies to other terminals.

  FIG. 2 is a diagram illustrating a configuration example of a terminal.

  The terminal 1 includes a management unit 11, a management data storage unit 12, an application 13, an OS (operating system) 15, and a wireless LAN interface unit 16. The management unit 11 includes an information acquisition unit 111, a class determination unit 112, and a time determination unit 113. The management data storage unit 12 includes a reception strength table 121, a communication speed table 122, a class value table 123, a time table 124, and an execution history table 125. The application 13 includes an activation unit 131 and a download unit 132.

  The wireless LAN interface unit 16 is a communication interface unit that receives radio waves. The wireless LAN interface unit 16 is a communication interface that receives radio waves from the wireless LAN station 2 and transmits radio waves to the wireless LAN station 2. The wireless LAN interface unit 16 is, for example, a wireless LAN card having an antenna that transmits and receives radio waves. The wireless LAN interface unit 16 transmits / receives data, in other words, transmits / receives wireless packets via the wireless LAN station 2 that is an access point in the cell 3. The communication between the wireless LAN interface unit 16 and the wireless LAN station 2 is a communication that conforms to a standard such as IEEE802.11a or IEEE802.11b.

  The wireless LAN interface unit 16 generates and holds network information each time data is transmitted to and received from the wireless LAN station 2. The network information includes, for example, an IP address, a MAC address, reception intensity of a received radio wave at the wireless LAN interface unit 16, and a communication speed at the wireless LAN interface unit 16. Note that a signal-to-noise ratio (S / N) may be used instead of the reception intensity.

  The OS 15 is a processing unit that executes a control program for controlling the terminal 1, and causes the management unit 11 to manage the startup time of the application 13. For example, the control program exists on the RAM and is executed on the CPU. The OS 15 acquires both the reception strength X and the communication speed V from the wireless LAN interface unit 16 in response to a request from the management unit 11, for example. The OS 15 sends the received reception strength X and communication speed V to the management unit 11. The OS 15 causes the application 13 to execute a job.

  The application 13 is, for example, a processing unit that executes an application program that is a business processing program, and processes a predetermined business. For example, the application program exists on the RAM and is executed on the CPU. The application 13 downloads a large amount of data from the host computer 1 via the wireless LAN station 2 in order to acquire data used for the business, update a security patch or a virus pattern, for example, at the business start time.

  The management unit 11 acquires the reception intensity X and the communication speed V from the OS 15. The management unit 11 executes the activation process of the application 13 by using the acquired reception strength X and communication speed V and the information stored in the management data storage unit 12.

  The management data storage unit 12 is a storage unit that is referred to by the management unit 11 and stores information for determining a communication class of received radio waves, information for starting the application 13, and the like. For example, the management data storage unit 12 is a hard disk device or the like.

  The information acquisition unit 111 acquires the reception intensity X and the communication speed V from the OS 15. For example, the information acquisition unit 111 sends an acquisition request for the reception strength X and the communication speed V to the OS 15 at a predetermined cycle. In response to this, the OS 15 sends the reception strength X and the communication speed V for each communication executed between the previous acquisition request and the current acquisition request to the information acquisition unit 111. The information acquisition unit 111 sends the received reception strength X and communication speed V to the class determination unit 112.

  The information acquisition unit 111 may acquire at least one of the reception intensity X and the communication speed V of the received radio wave in the wireless LAN interface unit 16.

  The class determination unit 112 determines a class based on both the received reception strength X and the communication speed V. The communication class represents the good communication quality of received radio waves by a hierarchy (class). That is, the higher the communication class, the better the communication quality. Note that the reception intensity X and the communication speed V are generally correlated with the reception error rate, and are a measure for evaluating the communication quality. Further, the communication class can be determined in more detail by using both the reception strength and the communication speed.

  Note that the class determination unit 112 may determine the communication class in the wireless LAN interface unit 16 based on at least one of the acquired reception strength X and communication speed V.

  The class determination unit 112 obtains a reception strength class C by referring to the reception strength table 121 using the acquired reception strength X, and refers to the communication speed table 122 using the acquired communication speed V to perform communication. The speed class D is obtained, and the class of communication is determined by referring to the class value table 123 using the obtained reception strength class C and communication speed class D.

  Specifically, the class determination unit 112 determines each representative value for each acquired time range for the reception intensity X and the communication speed V acquired from the information acquisition unit 111 prior to the determination of the communication class. . The class determination unit 112 determines a representative value for the plurality of reception strengths X and the plurality of communication speeds V in the acquired time range by using statistical processing such as simple averaging and moving smoothing, for example. Thereby, even when the communication environment of the wireless LAN changes every moment, the communication class can be determined stably.

  Next, the class determination unit 112 refers to the reception strength table 121 and the communication speed table 122 using the determined representative values of the reception strength X and the communication speed V, and determines the reception strength class C and the communication speed class D. Ask.

  Furthermore, the class determination unit 112 refers to the class value table 123 based on the obtained combination of the received strength class C and the communication speed class D, and determines a communication class. The communication class is represented by a weighted rank R, for example. The weighting rank R is a predetermined communication class based on a combination of the reception strength class C and the communication speed class D. The class determination unit 112 sends the determined communication class to the time determination unit 113.

  Note that the class determination unit 112 may determine the communication class using one of the reception strength table 121 and the communication speed table 122.

  The time determination unit 113 determines a time range (activation time range) for downloading information for updating the application 13 based on the determined communication class. The time determination unit 113 assigns an earlier time range as the time range in descending order of the determined communication class.

  Furthermore, the time determination unit 113 uses a unique value (hereinafter referred to as a unique value) determined in advance for the terminal 1 to determine the time for downloading information for updating the application 13 in the determined time range. decide.

  Specifically, the time determination unit 113 refers to the time table 124 and determines the allocation of the activation time range corresponding to the weighting rank R determined by the class determination unit 112. Further, the time determination unit 113 determines the activation time from the allocated activation time range using the unique value of the terminal 1. The time determination unit 113 determines a time (start time) for starting the application 13 based on the determined start time and the current time. When the activation time comes, the time determination unit 113 notifies the activation start of the application 13.

  Here, the unique value used by the time determination unit 113 will be described.

  When the communication classes of the plurality of terminals 1 are the same, there is a possibility that the activation times overlap as a result of overlapping of the allocated activation time ranges among the plurality of terminals 1. Therefore, the time determination unit 113 determines the activation time from the allocated activation time range using the eigenvalues of the terminals 1 so that the activation times do not overlap among a plurality of terminals 1 having the same communication class. The unique value is information uniquely determined for each terminal 1, such as a MAC address, an IP address, and a host name. The eigenvalue is acquired from the OS 15 by the information acquisition unit 111. Using this eigenvalue, a unique value is determined.

  Specifically, the unique value is a value generated from a unique value such as a MAC address or an IP address. When the unique value is a large value, the activation time in the activation time range is delayed. That is, even in the same communication class (same weighting rank R), the activation time is delayed. When the unique value is a small value, the activation time in the activation time range is advanced. In other words, even in the same communication class, the startup time is shortened.

  For example, in a business, there may be a case where an IP address for a guest user in the terminal 1 can be distinguished from an IP address assigned to a user related to a normal business (referred to as a normal user). In this case, by using an IP address as the eigenvalue, a startup time that is earlier than a guest user (such as a user who is not business-prioritized) in the allocated startup time range for a normal user (such as a user who is business-priority) Can be assigned. That is, when the normal user terminal 1 and the guest user terminal 1 are in the same communication class, the unique value generated from the unique value of the normal user IP address is the unique value generated from the unique value of the guest user IP address. Compared to the value, a relatively early activation time is set in the allocated activation time range.

  The activation unit 131 activates the application 13. Specifically, when the activation unit 131 receives a notification of activation start of the application 13 from the time determination unit 113 of the management unit 11, the activation unit 131 starts activation processing such as initialization of the application 13 and securing of a memory area.

  The download unit 132 downloads information for updating the application 13 through the wireless LAN interface unit 16 in the determined time range. Specifically, the download unit 132 requests the connection of the terminal 1 to the access point via the OS 15 in the startup process by the startup unit 131. After the terminal 1 connects to the access point, the download unit 132 downloads information for updating the correction software, update data, etc. of the application 13 via the wireless LAN interface unit 16 within the determined time range. To do.

  Next, various tables in the management data storage unit 12 will be described with reference to FIGS.

  FIG. 3A is a diagram illustrating an example of the reception strength table 121.

  The reception strength table 121 defines a reception strength class C based on the reception strength X. In the reception strength table 121, the higher the reception strength X, the higher the class. The reception strength table 121 is a table for determining which reception strength X of received radio waves, which is one of the communication quality evaluation measures, belongs to the reception strength class C classified for each predetermined reference range. It is. Which reception strength class C belongs is determined by the class determination unit 112 with reference to the reception strength range defined in the reception strength table 121.

  Specifically, the reception strength table 121 stores a reception strength range for each reception strength class. The reception strength class C is a predetermined class (hierarchy) in order to indicate which communication quality the reception strength X is. The reception strength range is a numerical range of reception strength in which a reference range for each reception strength class is determined in advance.

  For example, the reception intensity class C is classified into four stages such as C1 to C4 for each reception intensity range. C1 is the class with the strongest reception strength X, and is the class with the weakest reception strength X in the order of C2, C3, and C4. Reception strength class C is not limited to four stages. The reception strength table 121 includes a reception strength range “X ≧ a” for the reception strength class “C1”, “a> X ≧ b” for “C2”, “b> X ≧ c” for “C3”, “ “C> X” is stored for “C4”. For example, a = −50, b = −60, and c = −70 (the unit is dBm).

  Note that the remark shown in FIG. 3 (A) shows the evaluation of the reception strength as a reference. For example, the remark “very good” of the reception strength class C1 represents the class with the highest rank.

  The reception strength table 121 is stored in the management data storage unit 12 in advance. The reception strength table 121 is referred to by the class determination unit 112 and is used to determine which reception strength class C the reception strength X belongs to.

  FIG. 3B is a diagram illustrating an example of the communication speed table 122.

  The communication speed table 122 defines a communication speed class D based on the communication speed V. In the communication speed table 122, the higher the communication speed V, the higher the class. The communication speed table 122 is a table for determining which of the communication speed classes D classified into predetermined reference ranges belongs to the communication speed V of the received radio wave, which is one of the communication quality evaluation measures. It is. Which communication speed class D belongs is determined by the class determination unit 112 with reference to a communication speed range defined in the communication speed table 122.

  Specifically, the communication speed table 122 stores a communication speed range for each communication speed class. The communication speed class D is a predetermined class (hierarchy) in order to indicate which communication quality the communication speed V is. The communication speed range is a numerical range of communication speed in which a reference range for each communication speed class is determined in advance.

  For example, the communication speed class D is classified into four stages such as D1 to D4 for each communication speed range. D1 is the class with the fastest communication speed V, and is the class with the slowest communication speed V in the order of D2, D3, and D4. The communication speed class D is not limited to four stages. In the communication speed table 122, the communication speed range “V ≧ α” for the communication speed class “D1”, “α> V ≧ β” for “D2”, “β> V ≧ γ” for “D3”, “Γ> V” is stored for “D4”. For example. α = 50, β = 40, and γ = 30 (all units are Mbps).

  Note that the remarks shown in FIG. 3B refer to the evaluation of the communication speed. For example, the remark “very fast” of the communication speed class D1 represents the class with the highest rank.

  The communication speed table 122 is stored in the management data storage unit 12 in advance. The communication speed table 122 is referred to by the class determination unit 112 and used to determine which communication speed class D the communication speed V belongs to.

  FIG. 4A shows an example of the class value table 123.

  The class value table 123 determines a communication class based on the reception strength class C and the communication speed class D. Specifically, the class value table 123 stores a weighting rank R and a priority for each combination of the reception strength class C and the communication speed class D, for example. The combination of the reception intensity class C and the communication speed class D is a combination of the reception intensity class C in the reception intensity table 121 and the communication speed class D in the communication speed table 122.

  The weighting rank R is a communication class determined based on a combination of the reception strength class C and the communication speed class D. The weighting rank R is classified into four levels, for example, R1 to R4. The weighting rank R is not limited to four levels. The priority is a priority order that determines whether the activation time is to be advanced or delayed in the allocated activation time range. The priorities are ranked as 1 (highest priority communication class) to 4 (lowest priority communication class), for example.

  For example, the class value table 123 stores the weighting rank “R1” for the combination of the reception strength class “C1” and the communication speed class “D1” in the class value table 123 shown in FIG. The communication class of degree “1”. For example, when the reception strength class is “C4” and the communication speed class is “D4”, the weighting rank “R4” is stored, and the communication class has the lowest priority “4”.

  The class value table 123 is stored in the management data storage unit 12 in advance. The class value table 123 is referred to by the class determination unit 112 to determine which weighting rank R the combination of the reception strength class C and the communication speed class D is in other words, which is the communication class. Used for.

  Note that these weighting ranks R in the class value table 123 may be determined using only the reception strength class C or only the communication speed class D.

  FIG. 4B is a diagram illustrating an example of the timetable table 124.

  The timetable table 124 is a table for storing the activation time range for each weighting rank R. The activation time range is a time range during which the application 13 is activated by the time determination unit 113.

  Specifically, the timetable table 124 stores an activation time range and an activation time zone for each weighted rank. The activation time range is a numerical data range of a time range in which the application 13 is activated. The activation time zone is a time conversion value of numerical data indicated in the activation time range.

  For example, in the weighting rank “R1”, the activation time range “0000-0459” and the activation time zone “5 minutes” are stored. In this case, “0000” indicates 00 minutes and 00 seconds, and “0459” indicates 04 minutes and 59 seconds. That is, in the case of the weighting rank “R1”, the activation time range is from 0 minutes 0 seconds to 4 minutes 59 seconds.

  In the weighting rank “R2”, the activation time range “0500 to 0959” and the activation time zone “5 minutes” are stored. In this case, “0500” indicates 05 minutes 00 seconds, and “0959” indicates 09 minutes 59 seconds. That is, when the weighting rank is “R2”, the activation time range is 5 minutes 0 seconds to 9 minutes 59 seconds.

  Since the time required for the download process increases as the communication class decreases, the activation time period may be lengthened as the weighting rank “R2” decreases. For example, the weighting ranks “R1” to “R3” may be set to the activation time zone “5 minutes”, and the weighting rank “R4” may be set to the activation time zone “10 minutes”. As described above, the start-up time becomes slower as the communication class becomes lower.

  The time table 124 is stored in the management data storage unit 12 in advance. The time table 124 is referred to by the time determination unit 113 and used for calculating the activation time.

  It should be noted that the time table 124 may store a download time for designating a download (or activation) time. For example, a plurality of times such as “8:40”, “9:40”, “12:20”, “13:20”, “19:40”, “20:40” are stored as download times. May be. As a result, the necessary data update can be executed at the required time according to the business form. Further, for example, a table for storing the download time corresponding to each different application may be prepared.

  5A to 5D are diagrams illustrating an example of the execution history table 125 (125 ').

  The execution history table 125 is a table in which an execution flag indicating whether or not an application activation start notification has been executed and a history of the execution time are recorded. Accordingly, the execution history table 125 is updated by the time determination unit 113 every time an application activation start is notified. After the notification of the application activation process, the time determination unit 113 manages the execution flag so that the application activation start notification is not redundantly executed. Thereby, it is possible to prevent duplication processing from being executed until the next download time.

  Specifically, the execution history table 125 includes an execution flag 1251 and a date / time setting history 1252. The execution flag 1251 is set to on or off. The on state indicates that an application start command has been notified. The off state indicates that an application activation command is not notified. The date / time setting history 1252 records the date and time when the execution flag 1251 is set to ON.

  For example, as shown in FIGS. 5A and 5B, the execution flag 1251 in the execution history table 125 is set to ON. The date / time setting history 1252 indicates that the last execution flag 1251 ON setting date “2011/3/11” and the set time “9:47:37”.

  FIG. 5C and FIG. 5D are diagrams showing an example of the execution history table 125 ′, and the next history operation is executed from the execution history table 125 shown in FIG. 5A and FIG. 5B. It is a figure explaining.

  For example, as illustrated in FIG. 5C, it is assumed that the execution flag 1251 ′ is set off by the time determination unit 113 in the execution history table 125 ′. After the setting, when the time determination unit 113 notifies the start of application activation, the time determination unit 113 sets the execution flag 1251 ′ from off to on, and at the same time, as shown in FIG. In the time setting history 1252 ′, the history is recorded as the setting date “2011/3/12” and the setting time “9:47:36”.

  When the download process is executed only once a day, for example, after the notification of the download process, the time determination unit 113 prevents the application 13 from downloading every time the terminal 1 is started up. Specifically, the time determination unit 113 manages the execution history table 125 so that the execution flag is set to ON after the download processing notification and the double processing is not performed until the flag is cleared after the next day.

  FIG. 6 is an explanatory diagram of the connection status from the terminal to the access point in the wireless LAN system.

  In the cell 3, only one terminal 1 can communicate with the wireless LAN station 2 as an access point within the same time. For example, on the time axis, the occupation time T # 11 is a time during which the terminal # 1 is connected to the wireless LAN station 2.

  For example, the reception intensity of the received radio wave at the terminal # 1 is represented as “X # 1”, and the communication speed at the terminal # 1 is represented as “V # 1”. For example, reception intensity X # 1 (= −45 dBm)> X # 2 (= −65 dBm)> X # 3 (= −78 dBm), and communication speed V # 1 (= 54 Mbps)> V # 2 (= 48 Mbps) It is assumed that> V # 3 (= 24 Mbps). Further, the weighting rank of terminal # 1 is “R1”, the weighting rank of terminal # 2 is “R2”, and the weighting rank of terminal # 3 is “R3”.

  In FIG. 6, the time origin is set to 0 minute 0 second of the activation time. For example, in the terminal # 1, the time that is connected to the wireless LAN station 2, in other words, the occupation time is T # 11, T # 12, T # 13, and T # 14. In terminal # 2, the occupation times are T # 21, T # 22, T # 23, and T # 24. In terminal # 3, the occupation times are T # 31, T # 32, T # 33, and T # 34. Since only one terminal 1 can be connected to the wireless LAN station 2 in the cell 3 at the same time, the occupation times do not overlap.

  When viewed at the same packet traffic, the communication time depends on the communication quality. Therefore, when the occupation time T # 11 of the terminal # 1 and the occupation time T # 21 of the terminal # 2 are compared, the occupation time T # 21 is longer than T # 11. Furthermore, the occupation time T # 31 of the terminal # 3 is longer than T # 21.

  Since the start-up time is determined according to the communication class, as shown in FIG. 6, the terminal # 1 with the weighting rank R1 is assigned to the wireless LAN station 2 prior to the terminals # 2 and # 3 with the other weighting rank R. Can be connected. The terminal # 2 with the weighting rank R2 connects to the wireless LAN station 2 behind the terminal # 1 and prior to the terminal # 3. Terminal # 3 with weighting rank R3 connects to wireless LAN station 2 behind terminal # 1 and terminal # 2.

  Thereby, in the wireless LAN system, the terminal 1 having a higher communication class is connected to the wireless LAN station 2 prior to the other terminal 1 having a lower communication class, and the other terminal 1 is connected to the communication class. The wireless LAN station 2 is connected to the wireless LAN station 2 with a sufficient delay from the terminal 1 having a high value. As a result, it is possible to avoid the occurrence of a collision by a plurality of terminals 1 randomly requesting connection to the wireless LAN station 2, and the terminal 1 having a higher communication class preferentially executes download processing and the like. Can do.

  In addition, by using the unique value of the terminal 1 in the wireless LAN system, the terminal 1 with high business priority that prioritizes download processing and the terminal 1 with low priority such as use of a guest account in the same startup time range. Thus, the activation time can be differentiated and set. As a result, the terminal 1 having a high business priority can be preferentially completed in the same startup time range with a fast download process.

  FIG. 7 is a diagram illustrating an application management processing flow executed by the management unit 11.

  The information acquisition unit 111 acquires the current time and network information including the reception strength X and the communication speed V from the OS 15 (step S11).

  Next, the class determination unit 112 determines each representative value from the reception intensity X and the communication speed V acquired by the information acquisition unit 111 (step S12). For example, since the reception strength X and the communication speed V vary with time, in the acquired time range, the class determination unit 112 performs, for example, the average value, the maximum appearance value, and the like by using statistical processing such as the average value and the most frequently occurring value. A representative value Vav1 is calculated.

  The class determination unit 112 refers to the reception strength table 121 and the communication speed table 122, and determines the communication class using the representative values of the reception intensity X and the communication speed V (step S13). For example, when the representative value Xav1 ≧ a of the reception strength, the class determination unit 112 determines the reception strength class “C1” with reference to the reception strength table 121 illustrated in FIG. If α> representative value Vav1 ≧ β of the communication speed V, the class determination unit 112 determines the communication speed class “D2” with reference to the communication speed table 122 shown in FIG. As a result, the class determination unit 112 refers to the class value table 123 shown in FIG. 4A and, based on the combination of the reception strength class C and the communication speed class D, the weighting rank “R1” (communication class). To decide.

  Next, when the time determination unit 113 acquires the communication class (weighting rank R) from the class determination unit 112, the time determination unit 113 refers to the time table 124 and determines the activation time (activation time) (step S14). The details of the activation process will be described later with reference to FIG.

  The time determination unit 113 executes the application activation process according to the determined activation time (step S15), and then ends the process. Details of the application activation process will be described later with reference to FIG.

  After the notification of the application activation start by the time determination unit 113 as described above, the activation unit 131 of the application 13 is activated. After startup, the application 13 notifies the OS 15 in order to execute download processing. In response to this, the OS 15 issues a connection request to the wireless LAN station 2 as an access point via the wireless LAN interface unit 16. After connecting to the wireless LAN station 2, the download unit 132 of the application 13 executes download processing. Since the management unit 11 cannot control the start time of the download process of the application 13 after the application 13 is started, the download unit 132 of the application 13 controls the download time. Here, in the embodiment shown in FIG. 2, the download unit 132 starts the download process after the application 13 is started.

  FIG. 8 is a diagram illustrating a startup process flow executed by the management unit 11.

  The time determining unit 113 refers to the time table 124 and determines the activation time range from the communication class (weighted rank R) (step S21). For example, in the case of the weighting rank “R2”, the time determination unit 113 determines the activation time range “0500 to 0959” with reference to the time table 124 shown in FIG.

  The time determination unit 113 acquires the unique information (unique value) of the terminal 1 from the information acquisition unit 111 (step S22). For example, the time determination unit 113 acquires the IP address of the terminal 1 from the information acquisition unit 111 as a unique value, and processes the acquired unique value to obtain a unique value “+235”.

  The time determination unit 113 determines the activation time from the activation time range and the unique information (eigenvalue) (step S23). For example, when the activation time range is “0500 to 0959” in the case of the weighting rank “R2” and the unique value is “+235”, the time determination unit 113 activates the activation time RT1 = 0500 + 235 = 0735, that is, the activation time “7 minutes”. 35 seconds ".

  The time determination unit 113 determines the activation time (absolute time) based on the current time and the activation time (step S24). For example, the download time is “8:40, 9:40, 12:20, 13:20, 19:40, 20:40”, and the current time is 8:45:18. The time determination unit 113 selects the latest download time “9:40” with reference to the current time = 8: 45: 18 and the download time. The time determination unit 113 determines that the activation time AT1 to start downloading = the latest download time + activation time RT1 = “9:40” +7 minutes 35 seconds = 9: 47 minutes 35 seconds.

  The time determination unit 113 notifies the application 13 of the determined activation time AT1 (step S25), and thereafter ends the process.

  The above is the operation flow until the start time for starting download or the start time AT1 for starting the application accompanying the download is determined.

  FIG. 9 is a diagram illustrating an application activation process flow of the time determination unit 113. In the flow shown in FIG. 9, the application activation process is performed once a day.

  The time determination unit 113 checks the execution flag 1251 and the execution history 1252 with reference to the execution history table 125 (step S31). For example, the time determination unit 113 refers to the execution history table 125, the execution flag 1251 shown in FIG. 5A is “ON”, and the final ON setting is set from the execution history table 125 shown in FIG. It is checked that the date is “2011/3/11 9:47:37”.

  Next, the time determination unit 113 determines whether or not the execution flag 1251 is turned on after the next day from the previous execution of the application activation start notification (step S32). For example, when the check date is 2011/3/12, since the previous execution “2011/3/11 9:47:37” illustrated in FIG. 5B, the time determination unit 113 sets “2011/3 / It is determined whether the execution flag 1251 is turned on after “12”.

  When the execution flag 1251 has not been turned on after the day following the previous execution (No in step S32), the time determination unit 113 repeats step S31.

  When the execution flag 1251 is turned on after the previous day of the previous execution (step S32 Yes), the time determination unit 113 clears the execution flag 1251 of the execution history table 125 and sets it to off (step S33). For example, since it is the previous execution “2011/3/11 9:47:37” shown in FIG. 5B, the time determination unit 113 turns on the execution flag 1251 after “2011/3/12”. As shown in FIG. 5C, the execution flag 1251 ′ is cleared and set to “off”.

  Next, the time determination unit 113 determines whether the current time has reached the activation time (step S34). For example, the time determination unit 113 determines whether the current time has reached the activation time AT1 = 9: 47: 35.

  If the activation time AT has not been reached (No at step S34), the process of step S34 is repeated until the activation time AT is reached.

  When the activation time AT has been reached (Yes in step S34), the time determination unit 113 sets the execution flag 1251 to ON (step S35). For example, when the current time reaches the activation time AT1 = 9: 47: 35, the time determination unit 113 sets the execution flag 1251 to ON, and the execution history 1252 ′ as shown in FIG. Is recorded as “2011/3/12 9:47:36”. As a result, after the download is completed, the execution flag 1251 is set to ON so that the download is not performed every time the download time is repeated several times on the day, and the double processing is performed until the execution flag 1251 is cleared after the next day. Enables operation settings that are not performed.

  After setting the execution flag 1251 to ON, the time determination unit 113 notifies the application 13 of the start of activation (step S36) and ends the process.

  FIG. 10 is a diagram illustrating another configuration example of the terminal.

  The example of FIG. 10 includes an application 14 instead of the application 13 in the example of FIG. 2. The application 14 includes an information acquisition unit 141, a class determination unit 142, a time in addition to the activation unit 144 and the download unit 145. This is an example including a determination unit 143. In other words, this is an example in which the application 14 determines the download time. Therefore, the terminal 1 does not include the management unit 11. The information acquisition unit 141, the class determination unit 142, and the time determination unit 143 correspond to the information acquisition unit 111, the class determination unit 112, and the time determination unit 113 of FIG. The activation unit 144 and the download unit 145 correspond to the activation unit 131 and the download unit 132 in FIG. 2, respectively.

  In FIG. 10, the application 14 needs to be activated in order to determine the download time. Thereby, the download time is determined by the information acquisition unit 141, the class determination unit 142, and the time determination unit 143 executing the processing. Based on this, the activation unit 144 of the application 14 controls the start time of the download process. Therefore, even when the application 14 is activated, the application 14 itself can determine and manage the download time.

  FIG. 11 is a diagram showing a startup time management processing flow executed by the application.

  The information acquisition unit 141 acquires the current time, network information including the reception strength X and the communication speed V from the OS 15 as in step S11 illustrated in FIG. 7 (step S41).

  The class determination unit 142 determines each representative value from the acquired reception intensity X and communication speed V, similarly to step S12 shown in FIG. 7 (step S42).

  As in step S13 shown in FIG. 7, the class determination unit 142 refers to the reception strength table 121 and the communication speed table 122, and uses the representative values of the reception intensity X and the communication speed V to determine the communication class (weighting). Rank R) is determined (step S43).

  Similarly to step S14 shown in FIG. 7, when the time determination unit 143 obtains a communication class (weighted rank R) from the class determination unit 142, the time determination unit 143 refers to the time table 124 and determines the start time of the download process. (Step S44).

  The activation unit 144 causes the download unit 145 to execute a download process according to the determined activation time (step S45), and thereafter ends the process. Details of the download process will be described later with reference to FIG.

  FIG. 12 is a diagram showing a download processing flow executed by the application. Note that the download process of the application 14 will be described once a day.

  The activation unit 144 refers to the execution history table 125 and checks the execution flag 1251 and the execution history 1252 (step S51).

  The activation unit 144 determines whether or not the execution flag 1251 has been turned on after the day following the previous execution (step S52).

  If the execution flag 1251 has not been turned on after the previous day of the previous execution (No at Step S52), the process returns to Step S51, and Step S51 is repeated.

  When the execution flag 1251 is turned on after the day after the previous execution (step S52 Yes), the activation unit 144 clears the execution flag 1251 of the execution history table 125 and sets it to off (step S53).

  Next, the activation unit 144 determines whether the current time has reached the activation time AT (step S54).

  If the activation time AT has not been reached (No at step S54), the process of step S54 is repeated until it reaches.

  When the activation time AT has been reached (Yes in step S54), the activation unit 144 sets the execution flag 1251 to ON (step S55).

  The activation unit 144 sets the execution flag 1251 to ON, and notifies the download unit 145 of the start of execution of the download process (Step S56). Upon receiving this notification, the download unit 145 executes a download process via the wireless LAN interface unit 16, and then ends the process.
