Description

  The present invention relates to a telephone number dynamic assignment system and a computer program, and more particularly to a dynamic assignment system that dynamically assigns a telephone number displayed on a web page for each viewer and a computer program for the dynamic assignment system.

  2. Description of the Related Art Conventionally, a method of tracking a visit trend to a website by the same visitor using a cookie is known. A cookie is data including identification information generated by a web server and stored in a browser terminal. By including the identification information in a browsing request transmitted thereafter from the reader's terminal, the web server can specify a series of accesses by the same viewer, and an access log for each viewer is generated. .

  The access log is used for measuring the effectiveness of web advertisements, for example. When a certain viewer clicks on a web advertisement to visit a website, the effect of the web advertisement can be measured by the subsequent access log of the viewer. In particular, when a visitor makes an inquiry using an input form on a website, the probability that a click on a web advertisement will lead to an inquiry is measured by associating an access log including the inquiry with a click action on the web advertisement. be able to.

  However, if the viewer makes a telephone inquiry by looking at the telephone number displayed on the web page, the web server cannot link the inquiry with the access log and measures the effectiveness of the web advertisement. There was a problem that I could not. Accordingly, it is conceivable to associate the access log and the inquiry corresponding to the destination telephone number by assigning different telephone numbers depending on the viewer and recording them in the access log and obtaining the destination telephone number of the inquiry by telephone.

  A system that can count the number of telephone inquiries for each web advertisement has been conventionally known (for example, Patent Document 1). In the system of Patent Document 1, when a web advertisement including a display of a telephone number of an inquiry destination is posted on a website, the telephone number of the inquiry destination is set for a set composed of the website and an advertiser. By granting, the number of inquiries is counted for each web advertisement and used for billing processing for advertisement placement. Therefore, this system can be used only when the web advertisement includes a display of a telephone number. Moreover, this system does not assign a telephone number for each viewer, and does not acquire an access log for each viewer. Thus, this system does not link telephone inquiries with access logs.

JP 2007-148833 A

  In order to change the telephone number for each viewer, it is necessary to prepare telephone numbers that are at least equal to the number of viewers who visit the website at the same time. Furthermore, on the web server side, there is no way to determine whether or not the web page is closed at the viewing terminal, so it is necessary to maintain the telephone numbers assigned to all the viewers for a certain period of time. Therefore, it was necessary to prepare a huge number of telephone numbers. In addition, when more visitors than expected have visited the website, the prepared telephone numbers may be insufficient. By efficiently assigning a limited number of telephone numbers to the viewer, it is preferable that the viewer's inquiry can be associated with the access log without preparing a huge number of telephone numbers.

  The present invention has been made in view of the above circumstances, and by assigning a limited number of phone numbers to viewers who have accessed the website, it is possible to assign different phone numbers to more viewers. The purpose is to.

  Another object of the present invention is to specify an access trend on a website of a viewer who makes an inquiry by telephone after accessing the website.

  A system for dynamically assigning a telephone number according to a first aspect of the present invention includes a web page providing unit that provides a web page including a display of an inquiry telephone number based on a browsing request from a browsing terminal, and the browsing terminal And a session management unit that manages a session between the web page providing units, and a telephone that is assigned to the session by selecting any one of two or more predetermined first telephone numbers as the inquiry telephone number. A browsing status determination unit for determining a browsing status of the web page by the browsing terminal based on a browsing signal repeatedly transmitted during display of the web page by a description in the data of the web page according to a number allocation unit; And a deallocation unit that deallocates the first telephone number for the session based on the browsing status.

  By adopting such a configuration, it is possible to provide a web page including display of different contact telephone numbers. Further, by using the browsing signal transmitted during the display of the web page, it is possible to cancel the assignment of the first telephone number that is the contact telephone number according to the browsing status of the web page on the browsing terminal. For this reason, assignment of the first telephone number is not maintained for the viewer who has finished browsing the web page, and different first telephone numbers can be assigned to more viewers.

  In the telephone number dynamic allocation system according to the second aspect of the present invention, in addition to the above configuration, the telephone number allocating unit is not allocated to any of the other sessions for the new session. 1 telephone number is assigned.

  By adopting such a configuration, the first telephone number can be assigned differently for each viewer. Therefore, the assigned first telephone number can be associated with the access log on a one-to-one basis. it can.

  In addition to the above configuration, the dynamic allocation system for telephone numbers according to the third aspect of the present invention has a time interval from the start of display of the web page to the transmission of the first browsing signal after that. It is configured to be shorter than the interval.

  By adopting such a configuration, it is possible to detect at an earlier stage that the web page is closed immediately after the display of the web page is started. Thereby, the assignment of the first telephone number to the viewer who has a low possibility of inquiring can be canceled at an earlier stage from the start of the display of the web page. Furthermore, the transmission of browsing signals can be prevented from being concentrated by making the transmission interval of subsequent browsing signals longer.

  In the telephone number dynamic allocation system according to the fourth aspect of the present invention, in addition to the above configuration, the allocation canceling unit has an upper limit allocation time longer than the browsing signal transmission interval after the allocation of the first telephone number. It is configured to deallocate the first telephone number for the session that has passed.

  By adopting such a configuration, even when the web page is being browsed, the assignment of the first telephone number can be canceled as the upper limit assignment time elapses. Thereby, even when the browsing signal is continuously transmitted, such as when the browser is left without closing the web page, the first telephone number can be unassigned, and the assignable first It is possible to reduce the situation where there is a shortage of telephone numbers.

  In the telephone number dynamic allocation system according to the fifth aspect of the present invention, in addition to the above configuration, when the deallocating unit allocates each of the first telephone numbers to the other session, The assignment of the first telephone number to the other session for which the preferential assignment time has elapsed after the assignment of the first telephone number is released, and the telephone number assignment unit sends the first telephone to the new session. Configured to assign a number.

  By adopting such a configuration, even if each of all the first telephone numbers is assigned to another session, the first telephone number can be assigned to a new session. In particular, the first telephone number of a session whose priority allocation time has elapsed from the first telephone number assignment is canceled, so that the first value of the other session in which the expected value for the inquiry is lowered from the display of the web page is displayed. The first telephone number can be assigned to a new session having a high expected value.

  In the telephone number dynamic allocation system according to the sixth aspect of the present invention, in addition to the above configuration, when the deallocating unit allocates each of the first telephone numbers to the other session, The assignment of the first telephone number to the other session having the longest elapsed time after the assignment of the first telephone number is canceled, and the telephone number assignment unit sends the first telephone to the new session. Configured to assign a number.

  By adopting such a configuration, even if each of all the first telephone numbers is assigned to another session, the first telephone number can be assigned to a new session. In particular, since the assignment of the first telephone number that has passed the most time from the assignment is released and assigned to a new session, a telephone number can be assigned to a session with a higher expected value of an inquiry.

  In addition to the above-described configuration, the telephone number dynamic allocation system according to the seventh aspect of the present invention is configured such that the telephone number allocation unit performs the new session when there is no other session for which the priority allocation time has elapsed. On the other hand, unlike the first telephone number, the second telephone number that can be assigned to two or more sessions is assigned as the inquiry telephone number.

  By adopting such a configuration, even if a different first telephone number cannot be assigned for each session, it is possible to assign a second telephone number that can be assigned to two or more sessions. Thereby, even in a situation where the first telephone number cannot be assigned, it is possible to accept a browser inquiry using the telephone.

  In the telephone number dynamic allocation system according to the eighth aspect of the present invention, in addition to the above configuration, the telephone number allocation unit is managed by the session management unit even after the allocation of the first telephone number is canceled. There is a re-request for the web page in the session, and when any one of the first telephone numbers is newly assigned to the session, the first telephone number assigned last to the session is If it is not assigned to any of the other sessions, the first telephone number is newly assigned as the inquiry telephone number.

  By adopting such a configuration, even if the assignment of the first telephone number is canceled, the first telephone number is again assigned to the session by re-requesting the web page. Thereby, a 1st telephone number can be allocated to the viewer with the high expected value to an inquiry. In particular, since the first telephone number to be reassigned is assigned the same first telephone number as the telephone number assigned most recently, the discomfort felt by the viewer by changing the displayed telephone number can be eliminated. .

  In addition to the above configuration, a dynamic telephone number allocation system according to a ninth aspect of the present invention includes an access log holding unit that holds an access log for each session including the telephone number to be inquired, and an inquiry by telephone. An incoming call history holding unit that holds an incoming call history including an incoming call destination telephone number, and an incoming call matching unit that matches the access log and the incoming call history by checking the contact telephone number and the incoming phone number And is configured.

  By adopting such a configuration, it is possible to provide a web page including a display of a contact telephone number that is different for each viewer. For this reason, the access log and the incoming call history can be associated with each other by collating the inquiry telephone number associated with the access log with the incoming telephone number included in the incoming call history. Therefore, it is possible to specify the access trend on the website of the viewer who made the inquiry by telephone after browsing the website.

  A computer program for a telephone number dynamic allocation system according to a tenth aspect of the present invention provides a web page providing unit that provides a web page including a display of a contact telephone number based on a browsing request from a browsing terminal; A session management unit that manages a session between the viewing terminal and the web page providing unit, and a telephone number that is assigned to the session as one of two or more predetermined first telephone numbers as the inquiry telephone number An allocation unit, a browsing status determination unit for determining a browsing status of the web page by the browsing terminal based on a browsing signal repeatedly transmitted during display of the web page by a description in the data of the web page, and Based on the browsing status, the computer is used as a deallocating unit that deallocates the first telephone number for the session. Configured to function the data.

By referring to such a database, the administrator of the analysis server 5 can specify the access trend of the telephone inquirer or easily measure the effectiveness of the web advertisement.

  Further, the comparison unit 513 associates the access log with the incoming call history based on the inquiry status included in the incoming call history. For example, when a telephone inquiry is made while browsing a web page, the access log is associated with the incoming call history. On the other hand, when the telephone inquiry is made while the web page is not being browsed, the access log and the incoming call history are not associated. By configuring in this way, it is possible to prevent the incoming call history and the access log from being erroneously associated when a telephone inquiry is made after browsing of the web page is completed.

  Steps S101 to S104 in FIG. 6 are flowcharts showing an example of the operation of the web server 2 in FIG. In the figure, a processing procedure after receiving a browsing request from the browsing terminal 10 is shown. First, the session management unit 25 of the web server 2 specifies a session ID based on the browsing request and establishes a connection (step S101).

  Next, the telephone number assigning unit 26 selects any one of the telephone numbers in the telephone number master holding unit 23 as an inquiry telephone number and assigns it to the session (step S102). The web page providing unit 24 transmits a web page including the inquiry telephone number selected by the telephone number assigning unit 26 to the requesting viewing terminal 10 (step S103). Next, the session management unit 25 generates an access log based on the session ID, and stores the access log in the access log holding unit 22 in association with the inquiry telephone number (step S104).

  Steps S111 to S115 in FIG. 7 are flowcharts showing an example of the operation when the session ID is specified in the web server 2 in FIG. First, the session management unit 25 refers to the cookie acquired from the browsing terminal 10 and determines whether or not it is the first access (steps S111 and S112). The cookie is data including identification information such as a session ID stored in the browsing terminal 10 by the browser of the browsing terminal 10.

  At the first access, the browser of the browsing terminal 10 acquires a cookie including a session ID generated by the web server 2 from the web server 2 and stores the cookie in association with the URL of the website.

  If the access to the website is the first access, the session management unit 25 newly generates a session ID and updates the cookie (steps S114 and S115). For example, the session ID is determined using a random number generated with the current time as a trigger. On the other hand, when the access to the website is not the first access, the session management unit 25 extracts and uses the session ID from the cookie (step S113).

  Steps S121 to S128 in FIG. 8 are flowcharts showing an example of operations at the time of assignment of inquiry numbers in the web server 2 in FIG. First, in the case of a new session (step S121), the telephone number assigning unit 26 selects a telephone number that is not in use from among the telephone numbers registered in the telephone number master holding unit 23 as an inquiry telephone number. The busy flag is updated (steps S122 to S124).

  When all the telephone numbers registered in the telephone number master holding unit 23 are in use, the allocation cancellation unit 27 cancels the allocation of telephone numbers to other sessions for which the priority allocation time Ta has elapsed from the number allocation. The telephone number assigning unit 26 extracts such a telephone number (step S126), and if there is a corresponding telephone number, selects the telephone number as the inquiry telephone number and updates the busy flag (step S127, S123, S124). If there is no corresponding telephone number, the telephone number assigning unit 26 designates a telephone number that can be duplicated different from the telephone number registered in the telephone number master holding unit 23 as the inquiry telephone number (step S128).

  On the other hand, if it is not a new session, the telephone number assignment unit 26 determines whether or not the telephone number assigned to the session is valid, and if it is valid, continues to use the telephone number (step S125). ). For example, if the site viewer is not browsing a web page, the assigned number is invalid. Alternatively, the assignment number is invalid if it is assigned to another session. If the allocation number is invalid, the process proceeds to step S122.

First, the telephone number assigning unit 26 monitors the browsing signal from the browsing terminal 10 (step S201), and if the browsing signal is received during the first time T1 from the transmission of the web page, It is determined that the site viewer is browsing the web page, and the busy flag corresponding to the assigned number is updated together with the time information (steps S202 to S204).

  On the other hand, if the browsing signal is not received when the first time T1 has elapsed, the telephone number assignment unit 26 cancels the assignment of the telephone number and invalidates the busy flag (steps S202, S203, S209). .

  Next, the telephone number assignment unit 26 determines whether or not the telephone number assigned to the session is valid (step S205). If the assigned number is valid, the telephone number assignment unit 26 waits until the second time T2 elapses. If the browsing signal is received before the second time T2 elapses (step S206), it is determined that the site viewer is browsing the web page, and the process proceeds to step S204. (Steps S207 and S208).

  If the browsing signal is not received when the second time T2 has elapsed, the telephone number assignment unit 26 cancels the assignment of the telephone number and invalidates the in-use flag (steps S207 and S209). Further, if the assigned number becomes invalid before the second time T2 elapses, the telephone number assigning unit 26 transmits a viewing signal stop request to the viewing terminal 10 and ends this processing (step S210). ).

  Next, when the upper limit allocation time Tm has elapsed since the transmission of the web page, the telephone number allocation unit 26 cancels the allocation of the telephone number, invalidates the busy flag, and ends this process (steps S208 and S209). .
