  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a diagram for explaining an example of a schematic configuration of a download system 1 including a wireless communication terminal according to an embodiment of the present invention.

  As shown in FIG. 1, the download system 1 distributes a software update file to the wireless communication terminal 10 connected to the network N1 via the wireless communication relay device 30 or the base station 40 and to the wireless communication terminal 10 via the network N1. A distribution server 20 is provided.

  The wireless communication terminal 10 can receive communication services such as voice call and data communication by connecting to the network N1 via the base station 40, the wireless communication relay device 30, and the like. An example of data communication includes downloading a software update file.

  The wireless communication relay device 30 is a device that relays wireless communication by the wireless communication terminal 10, and the user uses the wireless LAN communication function built in the wireless communication terminal 10 to connect to the network N1 and provide a data communication service. You can enjoy it. The wireless communication relay device 30 is, for example, an access point such as Wi-Fi (registered trademark) that is a wireless LAN relay device installed in a home, a company, a school, a station premises, a fast food store in the city, and the like. Generally, the communication service providing range of the wireless communication relay device 30 is several meters to several tens of meters or less.

  The wireless communication terminal 10 is either connected to the mobile network N2 such as a communication carrier via the base station 40 or connected to the wireless communication relay device 30, that is, connected to Wi-Fi. Even in this case, the software update file can be downloaded through the network N1. The type of the wireless communication terminal 10 is not particularly limited as long as the wireless communication terminal 10 is a communication terminal that requires software such as a mobile phone such as a smartphone, a tablet terminal, or a personal computer that can download and rewrite an update file. Let's assume a mobile phone.

  FIG. 2 shows an example in which the distribution server 20 determines and specifies a distribution schedule for distributing the software update file to the wireless communication terminal 10. In FIG. 2, the wireless communication terminal 10 owned by each of the user A, user B, user C, and user D accesses the distribution server 20 via the network N1, and based on the distribution schedule determined in the distribution server 20, software The download request time of the update file is designated (the designated download request time is hereinafter referred to as a first download time). As an example of a delivery schedule determination method, the delivery server 20 may specify that the download request times of each accessed wireless communication terminal are distributed as evenly as possible within 24 hours. By determining the distribution schedule in advance so that the download times of the software update files are evenly distributed, it is possible to prevent the download requests from the wireless communication terminal 10 from being excessively concentrated in the same time zone, and to distribute the server 20 and the mobile network. And a load of a transmission network such as a Wi-Fi network can be distributed over time. By distributing the time, it is possible to avoid network load concentration due to the download of the software update file between the wireless communication terminal and the distribution server, and to reduce the possibility of the download being interrupted due to the occurrence of congestion.

  In FIG. 2, each wireless communication terminal 10 owned by the users A, B, C, and D based on the designation from the distribution server 20 has a ratio of 3 so that download requests for software update files are not concentrated in the same time zone. The first download time is specified by being distributed uniformly at 00, 9:00, 15:00, and 21:00. When each wireless communication terminal 10 reaches the first download time, it connects to the network N1 via the wireless communication relay device 30 or the base station 40, makes a download request for the software update file, and downloads the software update file from the distribution server 20. To do.

  The wireless communication terminal 10 is designated whether it is connected to the mobile network N2 via the base station 40 or connected to the Wi-Fi network via the wireless communication relay device 30. A download request is made when the download time is reached.

  For convenience of explanation, the example in which the first download time is designated for the wireless communication terminal 10 based on the distribution schedule determined in the distribution server 20 has been described. As an example of the load distribution method, the wireless communication terminal 10 When the user first turns on the power after obtaining the information, the wireless communication terminal 10 sets the interval for checking whether or not the distribution server 20 is updated, and the wireless communication terminal 10 distributes the data uniformly over 14 days and 24 hours. A method of distributing using random numbers or terminal eigenvalues on the communication terminal 10 side may be used.

  The description of FIG. 2 described above is merely an explanation for deepening the understanding of the contents of the present invention. Specifically, the present invention may be implemented in various embodiments described below, and may be implemented in various modifications without substantially exceeding the principle of the present invention. All such variations are within the scope of the present disclosure and the specification.

  FIG. 3 schematically illustrates an example of a functional configuration of the wireless communication terminal 10. The wireless communication terminal 10 includes a communication unit 102, a timing unit 104, a position acquisition unit 106, an action history storage unit 108, an optimal time zone calculation unit 110, a schedule setting unit 112, a comparison determination unit 114, a change unit 116, and a download request unit 118. A download execution unit 120, a storage unit 122, and a control unit 124. Note that it is not essential that the wireless communication terminal 10 has all these configurations.

  The control unit 124 is an arithmetic processing device such as a CPU that performs various arithmetic processes necessary for controlling each unit of the wireless communication terminal 10. In addition, each unit 102 to 122 described later is controlled by executing a predetermined program such as OS and firmware in the control unit 124, and a semiconductor device, an electronic circuit, other hardware, or software having the function, Or it can comprise as a functional module comprised by these combination.

  The communication unit 102 is a communication unit for communication connection to the network N1, and includes a mobile communication unit 102a and a Wi-Fi connection unit 102b. The mobile communication unit 102a is an interface for connecting to the base station 40 and communicating via a mobile network N2 such as a communication carrier. As this communication method, for example, WCDMA (registered trademark) (Multiband Code Multiple Access). ) And 3rd generation (3G) communication systems such as CDMA2000 (Code Division Multiple Access 2000), 4th generation (4G) communication systems such as LTE (Long Term Evolution), and 5th generation (5G) and subsequent communications. The method etc. are mentioned. On the other hand, the Wi-Fi connection unit 102b has a function corresponding to a communication method based on transmission / reception of IP packets in accordance with a standard such as a wireless LAN as a wireless communication interface. It is used when in a Wi-Fi network environment connected to the network 30. The communication unit 102 makes a communication connection to the network N1 using the mobile communication unit 102a or the Wi-Fi connection unit 102b, and sends communication environment information indicating the history of the communication environment actually connected to the action history storage unit 108. . The history of the communication environment that is actually connected for communication is, for example, the line type of the communication line connected by the communication unit 102, and may be a history of the communication method, communication speed, and the like. Further, Wi-Fi information detected by the Wi-Fi connection unit 102b may be transmitted.

  The clock unit 104 measures the date and time, the date and time, the day of the week, the current time, the time when the position is acquired, the time when the connection to the wireless communication relay device 30 is started and the time when the connection is terminated by the Wi-Fi connection unit 102b, the mobile The communication unit 102a generates time information including the time at which the connection to the network N2 is started, the time at which the connection is ended, and the download time of the software update file. The time counting unit 104 may use the time when the communication unit 102 connects to the desired base station 40 and requests registration of its own location information as the connection start time, or the time when registration of the location information is completed. Alternatively, the connection start time may be set. Further, the time measuring unit 104 may set, for example, a time at which the wireless communication terminal 10 is instructed to disconnect the connection with the wireless communication relay device 30 to which the control unit 124 is connected as a connection end time, The time at which the control unit 124 receives the notification of the disconnection completion from the wireless communication terminal 10 may be set as the connection end time. Note that the timer unit 104 includes, for example, a clock circuit. The time information measured by the time measuring unit 104 is sent to the action history storage unit 108.

  The position acquisition unit 106 acquires the position information of the wireless communication terminal 10 itself and sends it to the action history storage unit 108. The location information is geographical location information that can be acquired by a positioning function such as GPS installed in the wireless communication terminal 10, cell ID of the base station 40 of the mobile network N2, and wireless communication relay of the Wi-Fi network. It may be approximate location information using the device 30, and an identifier for identifying the connected base station, such as an SSID (Service Set Identifier) of the connected wireless communication relay device 30, is recorded as location information. Also good.

  The action history accumulation unit 108 associates the communication environment information, time information, and position information received from the communication unit 102, the time measurement unit 104, and the position acquisition unit 106, and accumulates them as an action history of the wireless communication terminal 10. Here, an example of a processing flow in which the wireless communication terminal 10 accumulates an action history will be described with reference to FIG.

  In FIG. 5, the time when the wireless communication terminal 10 is connected to the network N1 via the base station 40 or the wireless communication relay device 30 is set as a start. In step S <b> 502, the communication environment information connected by the communication unit 102 is sent to the action history storage unit 108, and the action history storage unit 108 records the time information received from the time measuring unit 104. Next, in step S504, whether the communication environment information connected by the communication unit 102 is a connection via the wireless communication relay device 30, that is, a Wi-Fi network, or a connection via the base station 40, that is, a mobile network. If it is a Wi-Fi network, SSID (Service Set Identifier) is recorded (step S506). Note that the SSID is a unique identifier included in a management frame periodically transmitted from the wireless communication relay device 30, and the wireless communication terminal 10 receives the SSID so that the Wi-Fi wireless network The existence can be confirmed.

  After performing step S506, or if the Wi-Fi connection is not established in step S504, position information is measured in step S508. The location information can be measured using cell ID information received from the base station 40 in addition to obtaining location information using the GPS function installed in the wireless communication terminal 10. If SSID is recorded in step S506, the SSID may be recorded as position information, and step S508 may be omitted.

  In step S510, the history of time information, location information, and Wi-Fi connection information is associated with each other and stored in the action history storage unit 108 as an action history of the user who owns the wireless communication terminal 10 for a certain period. And it returns to step S502 and repeats a series of flows. The interval of action history accumulation is not particularly limited, but is periodically performed once every hour, for example. Further, the period for repeating the accumulation of the action history is not particularly limited, but the longer the period, the more accurate the action history information.

  Here, an example of the data table stored in the action history storage unit 108 is shown in FIG. The example of FIG. 8 shows a case where the action history is accumulated for a certain period (three weeks in FIG. 8) for the wireless communication terminal 10 owned by a specific user. The communication unit 102, the time measuring unit 104, and the position acquisition unit 106 are shown. The time information, the position information, and the communication environment information (Wi-Fi connection information) sent to the action history storage unit 108 from each other are associated with each other in a table form.

  Returning to FIG. 3, the optimum time zone calculation unit 110 calculates an optimum time zone suitable for downloading the software update file based on the data table accumulated in the action history accumulation unit 108 for a certain period. A detailed flow for calculating the optimum time zone will be described later with reference to FIGS.

  As described with reference to FIG. 2, the schedule setting unit 112 schedules the first download time of the software update file designated from the distribution server 20. In addition to setting with the distribution schedule determined in the distribution server 20, the wireless communication terminal 10 may set the first download time schedule by itself using a random number or the like.

  The comparison determination unit 114 compares the time zone calculated by the optimal time zone calculation unit 110 with the time set by the schedule setting unit 112, and changes the first download time set in advance by the schedule setting unit 112. The determination result is transmitted to the changing unit 116. The determination as to whether or not to change is made, for example, by comparing whether or not the first download time set in advance in the schedule setting unit 112 is included in the optimal time zone of the download environment calculated in the optimal time zone calculation unit 110. Judge by.

  The change unit 116 determines the schedule when the comparison determination unit 114 determines that the first download time set in the schedule setting unit 112 is not included in the optimal time zone of the download environment and that the change is preferable as the download environment. The first download time set in the setting unit 112 is changed. If there are a plurality of optimum time zones, the download time is changed to the nearest optimum time zone from the preset first download time schedule (the changed download time is set as the second download time). .

  The download request unit 118 makes a download request for the software update file to the distribution server 20 when the download time of the software update file set by the schedule setting unit 112 is reached.

  The download execution unit 120 downloads the software update file from the distribution server 20.

  The storage unit 122 is a storage unit that stores software update file information. Examples of the software update file information include wireless communication terminal information, presence / absence of update, and the like.

  FIG. 4 schematically shows an example of the functional configuration of the distribution server 20. The distribution server 20 includes a communication unit 202, a distribution schedule determination unit 204, an update file storage unit 206, a download request reception unit 208, and a distribution unit 210.

The communication unit 202 is a communication unit for connecting to the network N1.
The distribution schedule determination unit 204 determines the distribution schedule of the software update file for the wireless communication terminal 10.

The update file storage unit 206 stores a software update file for performing defect correction and update of the wireless communication terminal 10.
The download request receiving unit 208 receives a download request for a software update file from the wireless communication terminal 10.
The distribution unit 210 distributes the software update file in response to the download request received by the download request reception unit 208.

FIG. 6 shows an example of a software update file download flow performed between the distribution server 20 and the wireless communication terminal 10.
First, as described in FIG. 2, the distribution server 20 determines a rough distribution schedule in the distribution schedule determination unit 204 (step S602), and notifies the wireless communication terminal 10 of the distribution schedule determined in step S604. In step S604, an instruction to limit the change width of the first download time that can be changed by the changing unit 116 of the wireless communication terminal 10 may be included.

The wireless communication terminal 10 notified of the distribution schedule from the distribution server 20 sets the first download time in the schedule setting unit 112 (steps S604 and S606).
The wireless communication terminal 10 in which the first download time is set calculates the optimum time zone as shown in FIG. 8 described later. When the first download time needs to be changed, the change unit 116 performs the second download. Make changes to the time. If no change is necessary, the process proceeds to step S610 without performing step S608.

  When the time measuring unit 104 detects that the first or second download time set by the schedule setting unit 112 is reached, the wireless communication terminal 10 requests the distribution server 20 to download a software update file.

Upon receiving the download request, the distribution server 20 checks whether the software stored in the update file storage unit 206 is updated. If there is an update, the distribution unit 210 sends a software update file to the wireless communication terminal 10. Distribute (step S612).
In step S 614, the received update file is downloaded via the network connected by the communication unit 102 and stored in the storage unit 122.

  In this description, the distribution schedule is set on the distribution server 20 side. However, when the power of the wireless communication terminal 10 is first turned on in order to distribute the load on the communication network, the wireless communication terminal 10 By setting an interval for confirming whether or not there is an update in the distribution server, a mechanism that is uniformly distributed over 14 days and 24 hours may be used.

  Next, by using FIG. 7, FIG. 8, and FIG. 9, the wireless communication terminal 10 calculates the optimum download time zone and then changes the first download time set by the schedule setting unit 112 to perform wireless communication. An example of the flow of processing from the optimization of the download environment of the terminal 10 to the request for downloading the software update file will be described. In FIG. 7, as an example of the user C set to 15:00 in FIG. 2, the time point when the action history data is accumulated for three weeks is started.

In step S <b> 702, the optimum time zone calculation unit 110 refers to the action history data (FIG. 8) accumulated in the action history accumulation unit 108.
In step S704, the presence / absence of a time zone estimated to be moving is confirmed from the action history data. For example, in FIG. 8, on the first Monday, it can be seen that the position has moved from position A to position B from 8:00 to 9:00. Further, the position moves from position B to position C from 10:00 to 11:00, moves from position C to position B before 15:00, and moves from position B to position A from 15:00 to 16:00. I guess that. In addition, for example, the position is continuously the same from 0:00 to 8:00, from 11:00 to 13:00, and after 16:00, it is estimated that the object is not moved.

  Further, since the position A is continuous after 16:00 on the first Monday, it is estimated that it has not moved, but on the second Monday and the third Monday, a change in position is observed after 19:00. Therefore, if the data for three weeks are taken, it is estimated that the user C is more likely to move than the possibility of being in the position A after 19:00.

  Returning to FIG. 7, in step S704, the optimal time zone calculation unit 110 determines that the time zone in which it is estimated that there is a high possibility that the mobile terminal is not moving is more mobile than the time zone in which the possibility is that the mobile device is likely to have moved. It is determined that there is a high possibility that the software update download environment is optimal. Then, for the time zone in which it is estimated that there is a high possibility of not moving, the process proceeds to step S706, and the environment where the wireless communication terminal 10 is located is more suitable as a download environment than other time zones, and the optimum time to be calculated is calculated. Raise the candidate level to indicate that the band should be a candidate. Note that the determination as to whether or not the user is moving may be determined based on a change in the SSID, which is an example of position information. For the time zone in which it is estimated that there is a high possibility of moving, the process proceeds to the next step S708 without increasing the candidate degree.

  Next, in step S708, it is determined whether the history of the communication environment connected by the communication unit 102 is a Wi-Fi connection. For example, from 9:00 to 10:00 on the first Monday in FIG. 8, it is determined that there is no movement at the position B, and the candidate degree as the optimum time zone is increased. -It can be seen that this is not a Fi connection. In addition, from 11:00 to 12:00 on the first to third Mondays, the position C is continuous, so there is a high possibility that it has not moved, and the candidate degree as the optimum time zone has increased, Since 11:00 on the first Monday and 11:00 on the second Monday are not in a Wi-Fi connection environment, it is highly likely that 11:00 units are not in a Wi-Fi connection.

  Of the optimal time zones in which the candidate degrees are increased in step S706, the time zone that is estimated to be highly likely to be in a Wi-Fi connection environment is highly likely not to be in a Wi-Fi connection environment. It is determined that it is necessary to further increase the candidate time of the optimum time zone as an environment in which the software update file of the wireless communication terminal 10 is to be downloaded from the time zone thus determined, and the process proceeds to step S710 to increase the candidate degree as the optimum time zone. . By performing the processing in step S708 and step S710, the optimum time zone can be calculated with priority given to the situation under the Wi-Fi connection environment. Therefore, the mobile data is not intended for the user who owns the wireless communication terminal 10. In addition to reducing the possibility of communication, the resource load on the mobile network N2 can be reduced.

  Then, the time zone in which the candidate degree is increased in step S704 and step S708 is calculated as the optimum time zone (step S712). The calculated optimum time zone may be, for example, 8 hours from 0:00 to 8:00 in (a) in FIG. 8, or 3 hours from 16:00 to 18:00 in (c). Alternatively, it may be set as 1 hour before and after 12:00 in (b).

  In step S714, the comparison determination unit 114 determines whether or not the first download time set in the schedule setting unit 112 matches the optimal time zone calculated in step S712 of the optimal time zone calculation unit 110. Judge by comparison.

  As a result of the comparison determination, if the set first download time matches the optimum time zone, the process proceeds to step S718, and a download request for the software update file is sent to the distribution server 20.

  As a result of the comparison determination, when the set first download time and the optimum time zone do not match, the first download time set by the changing unit 116 is changed and the second download time is set. For example, the changing unit 116 changes the download time so as to be included in the optimum time zone closest to the first download time set by the schedule setting unit 112.

  FIG. 9 shows an example in which the wireless communication terminal 10 of the user C in FIG. 2 optimizes the download environment when the first download time (T1) is set to 15:00 in the schedule setting unit 112. Indicates. The distribution server 20 is set to make a download request at T1, but from the past action history data of the user C (FIG. 8), (a), (b), and (c) of FIG. Is calculated, the time zone (c) a little later than T1 is determined to be a more suitable environment for downloading, and from 16:00 units (1c) of (c) closest to T1 to 18 : Change to the second download time so that it is included in the time zone of 00 units. The second download time (T2) may be anywhere as long as it is included in the optimum time zone (c), but is set to 16:30, for example, one and a half hours later. Since the first download time set in advance by the schedule setting unit 112 is originally set so that the download time is distributed with the other wireless communication terminals 10, when multiple optimal time zones are calculated, It is desirable to select the optimum time zone that is closest to the first download time set by the schedule setting unit 112.

  In addition, when the schedule is notified from the distribution server 20 to the wireless communication terminal 10 in advance, a change range in which the download time can be changed by the changing unit 116 may be set.

  When the first or second download time is reached in step S718, a software update file download request is sent to the distribution server 20, and the process ends. Note that the calculation of the optimal time zone and the optimization of the download environment may be performed periodically, and the second download time is a time that is more suitable for requesting an update file download as the user action history is accumulated. It may be updated while calculating.

  Further, the calculation of the optimum time zone has been determined that the candidate degree is high as the optimum time zone for the software update processing of the mobile terminal for the time zone in which there is no movement and the time zone in which Wi-Fi connection is established. If the communication destination 10 accessed via the wireless communication relay device 30 is a communication destination that requires high throughput, or the communication state of another application in the wireless communication terminal 10 is stored together as an action history, You may make it exclude the time slot | zone when the communication state is increasing. The time zone in which the communication state is increasing is, for example, a time zone in which data is uploaded in another application in the wireless communication terminal 10 or a game application that is likely to increase the communication amount is started. It refers to the time zone when the traffic volume is increasing and the time when the line usage rate increases. This prevents download requests according to the communication status history such as situations where other applications are overused, even during times when there is no movement and during times when Wi-Fi is connected. The success rate can be improved.

  Furthermore, in the present embodiment, the wireless communication terminal 10 collects position information, time information, and communication environment information as action history information. However, the wireless communication terminal 10 cooperates with a personal assistant service or the like that already stores similar action history data. Thus, action history information may be used. Thereby, the wireless communication terminal can be used as an action history for calculating the optimum time zone without newly collecting an action history for a certain period.

  As a result, the software update file download success rate is improved, the download environment suitable for each user is automatically optimized, and the occurrence of mobile data communication is suppressed, without any effort to the user. For example, the load on mobile network resources can be reduced.

It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
