Here, Patent Document 1 proposes a technique for appropriately distributing the load on the server and the transmission path and further improving the convenience of data download.
JP 2004-185114 A

  By the way, in Patent Document 1, the load distribution of the server is considered, but the state inside the communication terminal is not considered. That is, data is downloaded from the server when an application (for example, a Web browser that browses a Web page or a camera application that captures an image of a subject) is executed on the communication terminal according to a user operation. Then, there is a case where the application and data download compete with each other and a heavy load is applied to the communication terminal (a camera application or the like may not be used during data download).

  An object of the present invention is to provide a communication terminal capable of downloading data safely and stably in consideration of the load on the server side and the load on the server side.

  In order to solve the above problems, a communication terminal according to the present invention is a communication terminal that downloads data from a server that manages data, and when executing an application that exhibits a predetermined function, A log information recording unit for recording log information in association with a time when the application is executed, and a request for transmitting downloadable time information including at least one time zone information in which the data can be downloaded.

Download start request transmitting unit, and the download start request transmitting unit transmits the data to the server. By performing signal request, characterized in that it comprises a data receiving unit for receiving the data transmitted from the server.

  Further, the communication terminal includes a storage unit that stores a weighting value set for each application, and the selection unit is stored in the log information recorded in the log information recording unit and the storage unit. It is preferable to select one or a plurality of time zone information from one or more time zone information included in the downloadable time information acquired by the downloadable time acquisition unit based on the weighted value.

  According to the present invention, data can be downloaded and installed safely and stably.

  Embodiments of the present invention will be described below. FIG. 1 is an external perspective view of a communication terminal 1 that communicates with an external device (base station) according to the present invention.

  As shown in FIG. 1, the communication terminal 1 is a display in which an outer surface is formed by an operation unit side body 2 having an outer surface formed by a front case 2a and a rear case 2b, and a front case 3a and a rear case 3b.

The operation button group 11 is assigned with function setting operation buttons 13 for operating various functions such as various settings, telephone book functions, mail functions, and the like, and numbers and characters are assigned to input characters when inputting a telephone number or creating a mail. An input operation button 14 used sometimes and a determination operation button 15 for performing determination and scrolling in various operations are configured. Further, an earphone connector cap 16 and a cap 17 that covers an interface (not shown) for communicating with an external device (base station) are provided on the side surface of the operation unit side body 2. Furthermore, a cap 18 a that covers a charging connector (not shown) and a pair of charging contact portions 18 b are provided at the lower end of the operation unit side body 2. Note that the voice input unit 12 is used to input a voice uttered by the user of the communication terminal 1 during a call.

  The display unit side body unit 3 includes a display 21 for displaying various types of information and an audio output unit 22 for outputting the voice of the other party on the call. In addition, a communication unit 23 for performing infrared communication with another mobile phone device or the like is provided at the upper end of the display unit side body 3.

  The hinge mechanism 4 connects the operation unit side body 2 and the display unit side body 3 so that they move relatively. The operation unit side body 2 and the display unit side body 3 are connected to each other. Can be switched between a use state (open state) in which the two are open to each other and a storage state (folded state) in which the surface of the operation unit side body 2 and the surface of the display unit side body 3 face each other. It is configured. In the present embodiment, as an example of a communication device, a so-called foldable communication terminal 1 in which the operation unit side body unit 2 and the display unit side body unit 3 move relatively via a hinge mechanism 4 is given. However, the present invention is not a foldable type, but a sliding type in which one casing is slid in one direction from a state where the operation unit side casing 2 and the display unit side casing 3 are overlapped. In addition, a rotary type in which one casing is rotated around an axis along the overlapping direction, or the operation unit side casing unit 2 and the display unit side casing unit 3 are connected via a biaxial hinge. Further, the present invention can be applied to a case where the operation unit side body unit 2 and the display unit side body unit 3 are arranged in one housing (so-called straight type).

  Here, the communication terminal 1 is connected to the server 101 via the base station 100 as shown in FIG. The server 101 includes, for example, package data necessary for air download and update, cgi (Common Gateway Interface) data, and the like. In addition, the communication terminal 1 that uses air download (a method of transmitting data to the communication terminal 1 when a request for data download is received from the communication terminal 1) Reservations can be made. The server 101 has a schedule table for managing the time accessed by each communication terminal based on the reservation status.

  When the communication terminal 1 downloads data from the server 101 via the base station 100, the server 101 considers the load on the server 101 side and its own load (load determined from the operation status of the application). It has a function that can download data without applying a load.

  Here, a configuration for exhibiting the above-described function will be functionally described. As illustrated in FIG. 3, the communication terminal 1 includes a log information recording unit 51, a first transmission unit 52, a downloadable time acquisition unit 53, a selection unit 54, a second transmission unit 55, and a download time. A setting unit 56, a download start request transmission unit 57, and a data reception unit 58 are provided.

  When executing an application that exhibits a predetermined function, the log information recording unit 51 records log information in which the identification information of the application is associated with the time when the application is executed. The first transmission unit 52 transmits to the server 101 a transmission request for downloadable time information including one or more time zone information in which data can be downloaded.

  The downloadable time acquisition unit 53 acquires downloadable time information transmitted from the server 101 in response to the transmission request transmitted by the first transmission unit 52. The selection unit 54 searches the log information recorded in the log information recording unit 51 for a time when the application is not executed, and the downloadable time acquired by the downloadable time acquisition unit 53 based on the search result. One time zone information is selected from one or more time zone information included in the time information. The downloadable time information includes, for example, a table in which five candidate times are designated with priorities as downloadable times as shown in FIG. The candidate time may be one or more and is not limited to five.

  The second transmission unit 55 transmits download reservation information including the time zone information selected by the selection unit 54 to the server 101. The download time setting unit 56 sets the download start time based on the time zone information included in the download reservation information when the second transmission unit 55 transmits the download reservation information to the server 101.

  The download start request transmission unit 57 transmits a data transmission request to the server 101 at the start time set by the download time setting unit 56. The data receiving unit 58 sends a data transmission request to the server 101 by the download start request transmitting unit 57 and receives the data transmitted from the server 101.

  By configuring in this way, the communication terminal 1 determines the download execution time in consideration of the schedule on the server 101 side and the application start time grasped from the past history. Data can be downloaded in a time zone with low usage frequency, and data can be downloaded and installed safely and stably.

  Further, the communication terminal 1 may be configured to include a storage unit 59 that stores a weighting value set for each application. In such a configuration, the selection unit 54 acquires the downloadable time acquisition unit 53 based on the log information recorded in the log information recording unit 51 and the weighting value stored in the storage unit 59. One time zone information is selected from one or more time zone information included in the downloaded downloadable time information.

  Specifically, the weighting value for an application (Web browser, mail application, etc.) related to communication is increased, and the weighting value for an application (such as an application that displays thumbnails of images) not related to communication is decreased. Remember me.

  With this configuration, the communication terminal 1 refers to the storage unit 59 when selecting one time zone information from the time zone information included in the downloadable time information, and has a large weighting value. The time zone when the application is activated can be excluded, and data can be downloaded and installed safely and stably.

<Flow of processing to download data>
Here, the flow of processing until the communication terminal 1 determines a schedule for downloading data from the server 101 and downloads the data will be described with reference to the sequence chart shown in FIG.

  The communication terminal 1 connects to the server 101 when activation of a Web browser is requested, online sign-up is requested, or mail reception is requested (S1) according to a user operation. (S2). The server 101 notifies the communication terminal 1 of the latest software version information and checksum information (S3). The communication terminal 1 compares the version information and checksum information of the currently installed software based on the information notified from the server 101, and determines whether or not the latest software needs to be downloaded.

  When determining that the latest software needs to be downloaded, the communication terminal 1 requests the server 101 to acquire downloadable time information in order to make a download reservation (S4). For example, the server 101 transmits to the communication terminal 1 downloadable time information in which five different times as shown in FIG. 4 are designated as reservation candidates (S5).

  The communication terminal 1 refers to an application use frequency table, which will be described later in detail, and selects time zone information for executing download from the downloadable time information. Note that the selected time zone information is one or more. Further, the communication terminal 1 transmits the selected result to the server 101 and reserves the download time (S6). Further, the server 101 updates the schedule table according to the reservation operation by the communication terminal 1.

  The communication terminal 1 starts air download of data when the reserved time is reached. Note that the communication terminal 1 pops up information on whether or not to execute data download on the display 21 when another application is activated when air download of data is started, and the user's The intention is confirmed (S7). Then, the communication terminal 1 executes data download when data download is instructed by the user (S8). Further, when data download is not executed by the user's selection, the communication terminal 1 executes (S4) to (S8) and reschedules the data download time with the server 101 again.

<Reservation and execution method of data download>
Next, details of reservation and execution of the data download described above will be described with reference to the flowchart shown in FIG.
When the communication terminal 1 reaches the start time (reservation time) of air download (S11), the communication terminal 1 determines whether or not a predetermined application is being activated (S12) and activated. If it is determined that it is not in progress (No), data download is started as scheduled (S13), and if it is determined that it is being started (Yes), whether or not download is to be executed is confirmed. This is done to the user (S14). Whether or not the communication terminal 1 executes the download according to a mode that the user can understand (for example, a predetermined pop-up is displayed on the display 21, a predetermined sound is output from the speaker, or the LED is lit). Confirm the intention.

  The communication terminal 1 starts the download when the user's selection permits the download (Yes) (S13), and when the user's selection does not permit the download (No). Sets the time for downloading data again (S15).

<How to create a usage frequency table>
Next, a method for creating a usage frequency table will be described. The communication terminal 1 is required to have a mechanism for acquiring logs regarding the activation of various applications. Here, “application activation” includes (A) telephone call, (B) communication, (C) Java (registered trademark) application / camera application / one-seg viewing application, and (D) key of operation button group 11 There is a difference in functions such as pressing and (E) Flash / Gadget. Therefore, in the present invention, the convenience to the user is improved by considering the degree to which the user does not want to execute air download at the same time depending on the function used.

  For example, when the call function is operating, air download is the function that is most desired to be avoided. Further, when the function (E) is operating, it can be considered that the necessity of avoiding the execution of air download is low.

  Therefore, weighting is performed for each function, and the result is stored in the storage unit 59. For example, when a function related to (A) is executed when one operation of each function is executed, the weighting value is set to “4” once, and when a function related to (B) is executed, 1 is set. When the function related to (C) is executed, the weight value is set to “2”. When the function related to (D) is executed, the weight value is set to “3”. When the function relating to (E) is executed, the weighting value is set to “0” and added to each.

  Next, the log acquisition accompanying the activation of the application is difficult to manage when it is acquired at short intervals and the amount of data is enlarged. Therefore, in the present invention, for example, a log is acquired once every 10 minutes, and data for 24 hours is tabulated every 10 minutes. By doing so, for example, even if a data amount of 4 bytes is applied every 10 minutes, the file size is about 576 bytes (4 bytes × 144), so the data amount can be reduced. In addition, the smaller the data amount of the table, the less time is required for reference, and matching with data acquired from the server 101 side can be performed in a short time. Here, FIG. 7 shows an example of the “cumulative table” for one day.

  In addition, as the data in the table accumulates daily data, the numerical value increases and management becomes difficult. Therefore, from the viewpoint that the usage frequency of the application is important, for example, every day at midnight, the count table is converted into a cumulative table. In the accumulation table, for example, data up to the previous day and new data are added at a ratio of 4 to 1, and the number divided by 5 is set as a set value for each time.

  Furthermore, since the usage frequency data is not intended to acquire a fine time, it is assumed to be a value after a rounding operation is performed. Here, in the rounding calculation, for example, three data before and after the set time are added and the averaged value is determined as the final value of the “usage frequency table”. What is actually used is “cumulative data” up to the previous day. In addition, since there is no data on the first day of purchase, in this case, determination is made based only on downloadable time information (hereinafter referred to as a reservation table) of the server 101.

<Matching between usage frequency table and reservation table>
The communication terminal 1 acquires from the server 101 a reservation table (a plurality of (for example, five) time zones during which data can be downloaded are designated).

  Next, the communication terminal 1 multiplies the time zone specified in the reservation table by the value in the use frequency table, determines the data indicating the largest numerical value as the reservation time, and sets the determined reservation time as “download reservation”. Decide on "Time". Note that the communication terminal 1 reserves the determination using a schedule function or the like.

  Then, the communication terminal 1 notifies the server 101 of the reservation time. At this time, the server 101 updates the schedule table.

  Thereafter, the communication terminal 1 requests the server 101 to download data when the reserved time is reached.

  By configuring in this way, the communication terminal 1 determines the download execution time in consideration of the schedule on the server 101 side and the application start time grasped from the past history. Data can be downloaded in a time zone with low usage frequency, and data can be downloaded and installed safely and stably.
