  The present invention relates to a communication terminal device and a communication access method for managing access timing to a server.

  Conventionally, there is a technique for distributing communication access between client servers (see, for example, Patent Document 1).

  In recent years, a system has been considered in which a plurality of communication terminals have the same mail account using cloud technology, and the communication terminals transmit and receive electronic mail related to the same mail account. In this system, e-mail data (including header information and bibliographic information, as well as e-mail text and attached files) is stored on the cloud server. (Title, destination, etc.) and bibliographic information (various statuses for e-mail data, etc.) only. And when a user browses each electronic mail data, a communication terminal can display a mail text and an attached file by acquiring a mail text and an attached file from a cloud server.

  In a mail system using such a cloud server, a user can operate electronic mail data held in a communication terminal without connecting to the mail server. For example, by operating a communication terminal, a user creates a new folder in a mailbox held in the communication terminal, deletes e-mail data from the mailbox, or renames a folder or the like be able to. In this case, since only the e-mail data and folder held in the communication terminal are changed, the mail server and the communication terminal are not changed unless the same change is made to the e-mail data and folder held in the mail server. And inconsistencies in the stored e-mail data and folders.

  In order to eliminate the inconsistency, the communication terminal notifies the mail server of the change information, and the mail server reflects the change information in the data held in the mail server. Then, it is conceivable that other communication terminals that can use the same mail account automatically and periodically access the mail server to inquire whether or not a change has occurred in the mail server.

Since the timing is specified and the access timing of each communication terminal apparatus can be specified without calculating the delay time every time, the access timing among a plurality of communication terminal apparatuses can be efficiently distributed.

  In addition, a communication system according to the present invention includes a plurality of communication terminal devices according to the present invention and a server that receives access requests from the plurality of communication terminal devices at different timings. According to such a communication system, since access requests are received from a plurality of communication terminal apparatuses at different timings, a communication system in which access timings among a plurality of communication terminals are efficiently distributed can be realized.

A communication access step for communication access to the server.

  According to such a communication terminal device and communication access method, the delay time of the time width between the reference time adjacent to the reference time is calculated with a random number, which has the same reference time as other communication terminal devices. The access timing is specified based on each reference time and the delay time corresponding to the time width determined for each reference time, and the access timing of each communication terminal apparatus is determined without performing synchronization processing each time. Since it can identify, the access timing between several communication terminal devices can be distributed efficiently.

  The communication terminal device according to the present invention further includes an access cycle setting means for setting an access cycle corresponding to a time zone with high access frequency to the server longer than other access cycles. In this case, since the access cycle corresponding to the time zone when the access frequency from the communication terminal device to the server is high is set, the communication load of the server can be reduced.

(Configuration of communication terminal apparatus 300)
Next, the communication terminal device 300 will be described in detail. FIG. 2 is a block diagram illustrating functions of the communication terminal device 300. The communication terminal 300 includes a mail display control unit 301, a mail creation / editing unit 302, a mail related information holding unit 303, a data processing unit 304, a communication management unit 305, a delay time calculating unit 306, an access timing specifying unit 307, and server access. The unit 308 (communication access means) is included.

  The communication terminal device 300 configured in this way is configured by the hardware shown in FIG.

In addition, it is realized by reading and writing data in the RAM 12 and the flash memory 17. Hereinafter, each functional block will be described based on the functional blocks shown in FIG.

  The mail display control unit 301 controls display of a new mail creation screen and a mail list screen held by the communication terminal device 300.

  The mail creation / editing unit 302 performs input of mail, storage of mail, and the like based on an input operation by the user of the communication terminal device 300. When the mail creation / editing unit 302 receives a mail transmission request, the mail creation / editing unit 302 sends a transmission request to the mail server 100 via the communication management unit 305, which will be described later. To store.

  The mail related information holding unit 303 holds the mail data by distinguishing each folder. Specifically, the mail related information holding unit 303 is a database that holds mail data and information (folder data) related to a folder in which the mail data is stored.

  The data processing unit 304 performs an editing process of mail information or folder information based on an input operation by the user of the communication terminal device 300. That is, the data processing unit 304 edits mail data and folder data held by the mail related information holding unit 303 in response to an input operation by the user of the communication terminal device 300. Examples of the editing process include a process based on a change from an unread mail to a read mail, a process based on a change (folder movement) of a mail storage folder, and the like.

  Further, the data processing unit 304 registers the synchronization information acquired from the mail server 100 via the communication management unit 305 in the mail related information holding unit 303.

  The communication management unit 305 transmits and receives various types of information (email information and synchronization information) with the mail server 30.

  The delay time calculation unit 306 has the same reference time in the plurality of communication terminal apparatuses 300, generates a random number for each communication terminal apparatus 300, and calculates a delay time within a predetermined time width based on the reference time using the random numbers. To do. For example, when the random number has an upper limit and a lower limit, the delay time calculation unit 306 calculates the delay time by associating the calculated position of the random number with respect to the range from the upper limit to the lower limit and a position within the time width.

  The access timing specifying unit 307 specifies the access timing based on the delay time and the access cycle. Specifically, the access timing specifying unit 307 determines the access timing by adding the access period to the delay time. Here, the access timing is a timing of communication access to the mail server 100, and there are a method of calculating by time and a method of calculating by elapsed time from a predetermined reference time.

  The server access unit 308 performs communication access to the mail server 100 via the communication management unit 305 at the access timing specified by the access timing specifying unit 307 (hereinafter, communication access is also simply referred to as “access”).

  Next, a method for specifying the access timing will be described with reference to FIG. As a premise, each communication terminal device 300 holds a common reference time (for example, midnight) in each communication terminal device 300.

  When each communication terminal device 300 starts a mail application, the delay time calculation unit 306 calculates a delay time within a predetermined time width based on the reference time using a random number. Specifically, the delay time calculation unit 306 generates a random number, calculates a delay time corresponding to the random number within the dispersion width T1, which is a predetermined time width, and the access timing specifying unit 307 The delay time is specified based on the delay time. In addition, the access timing specifying unit 307 specifies the delay time by adding the delay time to the reference time.

  In the example of FIG. 4, the delay time calculation unit 306 of the communication terminal device 300A generates a random number, calculates the delay time A corresponding to the random number within the distribution width T1, and the access timing specification unit 307 And the delay time t1 is specified based on the delay time A. On the other hand, the delay time calculation unit 306 of the communication terminal device 300B generates a random number, calculates the delay time B corresponding to the random number within the distribution width T1, and the access timing specifying unit 307 determines the reference time and the delay. Based on the time B, the delay time t2 is specified. Similarly, each delay time calculation unit 306 of communication terminal device 300C and communication terminal device 300D calculates a delay time corresponding to the random number, and access timing specifying unit 307 specifies the delay time from the reference time and the delay time. .

  The delay time, which is a delay time from the reference time, is the first access timing to the mail server 100 by each communication terminal device 300. Then, the next access timing to the mail server 100 is calculated by adding the same period T2 in each communication terminal device 300 to the delay time specified by the access timing specifying unit 307. In the case of the communication terminal device 300A, when the delay time calculation unit 306 calculates the delay time using random numbers and the access timing specifying unit 307 specifies the time t1 based on the reference time and the delay time, the access timing specifying unit 307 The time t1 is specified as the first access timing to the mail server 100, and the time t5 obtained by adding the period T2 to the time t1 is set as the next access timing. Thereafter, the access timing specifying unit 307 specifies the access timing by adding the period T2 to the time t5. Note that the length of the period T2 is equal to or longer than the dispersion width T1.

  Next, the processing procedure for specifying the access timing and accessing the mail server 100 based on the access timing will be described with reference to the flowchart shown in FIG.

  First, when the communication terminal device 300 starts a mail application in response to an input operation by a user of the communication terminal device 300 (step S1), the delay time calculation unit 306 stores a reference time held by the communication terminal device 300. The reference time is specified by reading (step S2). Then, the delay time calculation unit 306 generates a random number to calculate a delay time corresponding to the random number in the distribution width T1, and the access timing specifying unit 307 specifies the delay time based on the reference time and the delay time ( Step S3).

  Subsequently, the access timing specifying unit 307 specifies the access timing based on the delay time and the cycle. Specifically, the access timing specifying unit 307 specifies the latest access timing by adding a period to the delay time and comparing the current time with the added result (step S4).

  The server access unit 308 accesses the mail server 100 at the timing when the server access time, which is the access timing, is reached (step S5; YES) (step S6).

  Next, a modified example in which the access timing is shifted based on a plurality of reference times and delay times will be described.

  First, the concept of the operation of this modification will be described with reference to FIG. FIG. 6A shows an example in which the cycles are equally divided. In this case, as shown in FIG. 6 (B), the user explicitly states from 8 o'clock to 12 o'clock (5th cycle to 6th cycle) and from 18:00 to 22:00 (10th cycle to 11th cycle). When the server access by the communication terminal device 300 frequently occurs in response to various operations, the periodic access from the communication terminal device 300 is performed for the time period in which the server access by the explicit operation by the user frequently occurs. It is desirable to reduce the frequency.

  Therefore, as shown in FIG. 6C, a plurality of consecutive cycles with high server access frequency by the explicit operation of the user are combined into one, and the mail server 100 of the communication terminal device 300 in each cycle is sent to the mail server 100. Allow access only once.

  The functional configuration of the apparatus in this modification is the same as that shown in FIG. 2, but the delay time calculation unit 306 and the access timing specification unit 307 perform the following operations.

  The delay time calculation unit 306 includes a reference time table (storage means) that stores a plurality of reference times. FIG. 7 shows a specific example of this reference time table. As shown in FIG. 7, here, the reference time is assigned every 2 hours, but the time zone in which server access frequently occurs is 4 hours apart.

  The delay time calculation unit 306 generates a plurality of cycles using this reference time table. That is, the delay time calculation unit 306 functions as a time width calculation unit, and associates a time width between a reference time adjacent to each reference time with the reference time for each of the plurality of reference times. Is calculated.

  FIG. 8 is an explanatory diagram conceptually showing each cycle and access timing. First, the delay time calculation unit 306 calculates the time width of each cycle assigned for each reference time based on the reference time table. In FIG. 8, a time width of 2 hours is calculated in association with the reference time for the third cycle and the fourth cycle, and a time width of 4 hours is calculated for the fifth cycle. In addition, since this time zone is a time zone with high access frequency, the reference time is set so that a longer time span than other time zones can be taken. The delay time calculation unit 306 associates the time width calculated as described above for each reference time.

  Then, the delay time calculation unit 306 generates a random number, and calculates the delay time X and the delay time Y based on the generated random number and each time width. Note that X <Y is calculated. Again, the delay time calculation unit 306 holds the reference time and the delay time in association with each other.

  Then, the access timing specifying unit 307 specifies the access timing based on the reference time, the delay time X, and the delay time Y. That is, here, the access timing can be specified by adding the delay time X or Y associated with the time width assigned to each reference time to each reference time. In FIG. 8, server accesses t11 to t13 correspond to access timing.

  As described above, the communication terminal device 300 accesses the mail server 100 by setting the access timing interval longer in the time zone in which the access frequency by the explicit operation is higher than in other time zones. The frequency can be lowered.

  The processing procedure of the communication terminal apparatus 300 in this modification will be described using the flowchart shown in FIG. As described above, the communication terminal device 300 holds the start time (corresponding to the reference time) of each cycle, or is configured to be able to specify the start time (for example, from the mail server 100 at a predetermined timing). It is assumed that the information of the start time is acquired).

  First, when the communication terminal device 300 activates a mail application in response to an input operation by a user of the communication terminal device 300 (step S11), the delay time calculation unit 306 performs each cycle held by the communication terminal device 300. The reference time is specified by reading the start time (step S12). Then, the delay time calculation unit 306 generates a random number (step S13). The delay time calculation unit 306 calculates the length of each cycle from information on the start time of each cycle (step S14). Next, the delay time calculation unit 306 calculates a delay time based on the random number so as to be included in the range of the length of each cycle (step S15), and the access timing specifying unit 307 determines the delay time and each cycle. The access timing of each cycle is specified based on the start time (step S16).

  Subsequently, the access timing specifying unit 307 specifies the latest access timing by comparing the current time with the access timing of each cycle (step S16).

  The server access unit 308 accesses the mail server 100 at the timing when the server access time, which is the access timing, is reached (step S17; Yes) (step S18).

  Next, the effect of the communication terminal device 300 according to the present embodiment will be described. According to the communication terminal device 300 according to the present embodiment, the mail server 100 and the plurality of communication terminal devices 300 are communicably connected, and the delay time calculation unit 306 has the same reference as the other communication terminal devices 300. A delay time within a time width based on the time is calculated by a random number, and the access timing specifying unit 307 specifies an access timing based on the reference time, the delay time, and a cycle T2 for accessing at a predetermined cycle, and the server The access unit 308 performs communication access to the mail server 100 at the access timing specified by the access timing specifying unit 307.

  According to such a communication terminal device 300, a delay time within a time width based on the same reference time as the other communication terminal device 300 is calculated by a random number, and the access timing is determined based on the delay time and the access cycle. Since the access timing of each communication terminal apparatus 300 can be specified without generating a random time every time and calculating the delay time, the access timing among the plurality of communication terminal apparatuses 300 can be efficiently distributed. be able to.
