The storage unit 22 also stores OS (operating system) data that provides an interface with the hardware of the device itself, a program for reading the medium description information (hereinafter referred to as “reading program”), a browser, and the like. I remember it. When HTTP communication is performed by the function of the browser, the storage unit 22 stores data called a cookie for transmitting information about the own device to a web server such as the server device 10. The cookie stores, for example, a user ID used for logging in to the site, an already accessed link, information for identifying the communication terminal 20 (hereinafter referred to as “terminal identification information”), and the like. The information stored in the cookie is described in a header of an HTTP request transmitted by HTTP communication, for example, and transmitted to the web server.

  The UI unit 23 includes a display surface and a touch panel superimposed on the display surface, and receives an operation from the user and displays an image. The UI unit 23 supplies operation data corresponding to the received user operation to the control unit 21, and the control unit 21 performs processing according to the operation data. The first communication unit 24 includes a communication circuit for performing mobile communication, and transmits and receives data via the network 2. The second communication unit 25 includes a communication circuit for performing NFC wireless communication, and supplies the received data to the control unit 21 through wireless communication. The second communication unit 25 is used to read medium description information when the medium 3 performs NFC wireless communication. The photographing unit 26 has a function as a digital camera, for example, and photographs an image according to a user operation. The imaging unit 26 supplies image data indicating the captured image to the control unit 21. The photographing unit 26 is used for reading medium description information when the medium 3 represents a QR code.

  FIG. 3 is a diagram illustrating an example of a hardware configuration of the server device 10. The server device 10 is a computer that includes a control unit 11, a storage unit 12, and a communication unit 13. The control unit 11 has a common configuration with the control unit 21 of the communication terminal 20. The storage unit 12 includes a hard disk or the like, and stores data and programs used by the control unit 11 for control. The communication unit 13 includes a communication circuit for communicating with the network 2 and transmits and receives data to and from the communication terminal 20 via the network 2.

[1-3] Functional Configuration The server device 10 and the communication terminal 20 perform the parameter delivery process described above based on the hardware configuration described above. In the server device 10, the control unit 11 executes the program stored in the storage unit 12 to control each unit, thereby realizing the functions described below, and parameter passing processing is performed by the function of those functions. .
FIG. 4 is a diagram illustrating an example of a functional configuration of the server device 10. The server device 10 includes a receiving unit 101, a storage unit 102, a first instruction unit 103, and a second instruction unit 104.

[1-3-1] Receiving means 101
The receiving unit 101 is a unit that receives application identification information, parameters, and terminal identification information for identifying the communication terminal 20 transmitted from the communication terminal 20 by a browser function executed in the communication terminal 20. When the control unit 21 of the communication terminal 20 reads the medium description information by the function of the reading program, it passes the read medium description information to the OS. In the following, for the sake of brevity, it is assumed that the program is represented as the main subject of operation such that the reading program passes the medium description information to the OS. However, the actual operation subject is the control unit 21 that executes the program.

  In the communication terminal 20, the OS passes the medium description information passed from the reading program to the browser, and the browser identifies the application identification information included in the medium description information and the URL included in the medium description information, and An HTTP request in which a parameter and terminal identification information are described in a header is transmitted. When the browser has performed HTTP communication with the server device 10, a cookie used for HTTP communication with the server device 10 is stored in the storage unit 22, and the terminal identification information of the own terminal is stored in the cookie. ing. In this case, the browser describes the terminal identification information stored in the cookie in the header of the HTTP request.

  If the browser has never performed HTTP communication with the server device 10, such a cookie is not stored in the storage unit 22. In that case, the browser performs HTTP communication once with respect to the URL, and generates a cookie used for HTTP communication with the server device 10. At that time, since the terminal identification information is stored in the cookie, the browser describes the stored terminal identification information in the header of the HTTP request. The receiving unit 101 receives the application identification information, parameters, and terminal identification information described in the header of the HTTP request transmitted by the browser function. The receiving unit 101 supplies the received information to the storage unit 102, the first instruction unit 103, and the second instruction unit 104.

[1-3-2] Storage unit 102
The storage unit 102 is a unit that stores the application identification information and parameters received by the receiving unit 101 in association with the terminal identification information received by the receiving unit 101. For example, the storage unit 102 stores the information in a terminal identification information table in which application identification information and parameters are associated with terminal identification information.
FIG. 5 is a diagram illustrating an example of the terminal identification information table. In this example, “APP — 001”, “CONTENTS — 01” and “xxxx” are displayed in the first line of the terminal identification information table, and application identification information, parameters and terminal identification information “APP — 001”, “CONTENTS — 02” and “yyyyyy” are displayed in the second line. Is stored. The storage unit 102 notifies the first instruction unit 103 of the area in which the terminal identification information table is stored.

[1-3-3] Second instruction means 104
When the application identified by the application identification information received by the receiving means 101 is not installed in the communication terminal 20 identified by the terminal identification information received by the receiving means 101, the second instruction means 104 This is means for instructing the OS executed in the communication terminal 20 to install the application. Hereinafter, this instruction performed by the second instruction unit 104 is referred to as “installation instruction”. The second instruction unit 104, for example, a Java (registered trademark) script that causes the communication terminal 20 to execute this installation instruction in response to an HTTP response transmitted from a browser, and application identification information as an argument thereof. Is described.

  When the browser executed on the communication terminal 20 executes the JavaScript described in the received HTTP response, the browser determines whether the application identified by the application identification information that is the argument is installed in the terminal. When it is determined that the application is not installed, an HTTP request describing the application identification information is transmitted to the application providing device 30. The OS of the communication terminal 20 installs the application transmitted from the application providing apparatus 30 in response to this HTTP request in its own terminal. In this way, the second instruction unit 104 performs the installation instruction described above by describing Javascript in the HTTP response. When the second instruction unit 104 issues an installation instruction, the second instruction unit 104 notifies the first instruction unit 103 accordingly.

[1-3-4] First instruction means 103
The first instruction unit 103 passes the received parameter to the application identified by the received application identification information, to the browser executed in the communication terminal 20 identified by the received terminal identification information. It is a means of indicating. Hereinafter, this instruction performed by the first instruction unit 103 is referred to as “parameter delivery instruction”. For example, the first instruction unit 103 adds a description instructing to activate the application identified by the received application identification information and to pass the received parameter to the activated application in the above HTTP response. To do.

  When the browser running on the communication terminal 20 receives the HTTP response, the browser identified by the app identification information is activated and parameters are passed to the activated app as described in the HTTP response. . As described above, the first instruction unit 103 performs the parameter delivery instruction by adding the above description to the HTTP response. Note that if the instructed application has already been installed, the browser of the communication terminal 20 passes the parameters as instructed by the parameter delivery instruction. If the instructed application has not been installed, the application cannot be activated. In that case, the application is installed according to the installation instruction of the second instruction means 104 described above.

  The first instruction unit 103 receives the application identification information and the terminal identification information stored in the storage unit 102 after the application is installed in the communication terminal 20 according to the instruction from the second instruction unit 104. If received, the browser executed in the communication terminal 20 is instructed to pass the parameters stored in the storage means 102 in association with the terminal identification information to the application. In the communication terminal 20, when the OS finishes installing the application according to the installation instruction from the second instruction unit 104, the installed application is automatically activated.

  Only when the activated application is activated for the first time by the OS, the URL of the server device 10 and application identification information for identifying the application itself are notified to the browser, and the application identification information and the terminal identification information are displayed. A request is made to transmit the HTTP request described in the header to the URL of the server device 10. When the browser running on the communication terminal 20 receives this request, the URL of the server device 10 notified of the HTTP request in which the notified application identification information and the terminal identification information stored in the cookie are described in the header is received. Send.

  The receiving unit 101 receives the application identification information and the terminal identification information described in the header of the HTTP request transmitted in this way. The first instruction means 103 notifies the storage means 102 when the application identification information and the terminal identification information are supplied from the receiving means 101 after the second instruction means 104 notifies that the installation instruction has been made. The parameter stored in association with the received terminal identification information is read with reference to the terminal identification information table stored in the stored area. The first instruction means 103 includes a description instructing the HTTP response to activate the application identified by the application identification information described in the HTTP request header and to pass the read parameter to the activated application. to add. Thereafter, as described above, the communication terminal 20 performs a process of passing parameters to the application activated in accordance with the parameter delivery instruction.

[1-4] Operation The server device 10 and the communication terminal 20 perform the above-described parameter delivery process in cooperation with each other based on the above configuration. Hereinafter, the case where the display application displays content will be described as an example, and the operation of each device in the parameter passing process will be described with reference to FIGS. 6 and 7. In FIG. 6, an operation when an application is already installed in the communication terminal 20 will be described.
FIG. 6 is a sequence diagram illustrating an example of the operation of each device in the parameter passing process. Hereinafter, the operation of the communication terminal 20 will be described mainly with a program (reading program, OS, browser, application) that realizes each operation.

  The parameter passing process is started, for example, when the reading program of the communication terminal 20 reads the medium description information from the medium 3 (step S11). The reading program passes the read medium description information to the OS (step S12), and the OS passes this medium description information to the browser (step S13). The browser uses the URL of the server device 10 described in the medium description information as a destination, application identification information for identifying the display application, content identification information (a parameter in this example) for identifying the content to be displayed on the display application, and the communication terminal 20. An HTTP request describing the terminal identification information is transmitted (step S14). The server device 10 stores the application identification information, content identification information, and terminal identification information described in the HTTP request received in step S14 in a terminal identification information table as shown in FIG. 5 (step S15). Step S14 is an operation performed by the receiving unit 101, and step S15 is an operation performed by the storage unit 102.

  Next, the server device 10 adds a description instructing to start the display application and pass content identification information to the display application to the HTTP response, and installs the display application when the display application is not installed. Javascript is described and transmitted to the communication terminal 20 (step S16). Step S <b> 16 is an operation performed by the first instruction unit 103 and the second instruction unit 104. The browser of the communication terminal 20 executes JavaScript described in the received HTTP response, and in the example of FIG. 6, it is determined that the display application has been installed in the own terminal (step S17). Then, the browser activates the display application as described in the HTTP response (step S18), and passes the content identification information described in the HTTP response to the activated display application (step S19). By performing the parameter passing process as described above, the content identification information is passed to the display application, and the content identified by the passed content identification information is displayed by the display application.

Next, an operation when the display application is not installed in the communication terminal 20 will be described with reference to FIG.
FIG. 7 is a sequence diagram illustrating another example of the operation of each device in the parameter passing process. In the example of FIG. 7, firstly, the same operation is performed from step S11 (reading medium description information) to step S16 (transmission of HTTP response) shown in FIG. The browser of the communication terminal 20 executes JavaScript described in the HTTP response received in step S16, and determines that the display application is not installed (not installed) in its own terminal (step S21).

  Next, the browser transmits an HTTP request describing the application identification information to the application providing apparatus 30 (step S22), and the application providing apparatus 30 transmits the display application requested by the HTTP request to the communication terminal 20 (step S22). S23). The OS of the communication terminal 20 installs the display application downloaded in step S23 on its own terminal (step S24), and starts the display application when the installation is completed (step S25). The activated display application requests the browser to send an HTTP request (step S26). In response to the request, the browser sends an HTTP request describing the application identification information and the terminal identification information to the URL of the server device 10. As a destination (step S27).

  The server device 10 that has received the HTTP request transmits an HTTP response to which a description instructing to pass content identification information to the display application is added to the communication terminal 20 (step S28). Step S27 is an operation performed by the receiving unit 101, and step S28 is an operation performed by the first instruction unit 103. The browser of the communication terminal 20 passes the content identification information described in the HTTP response to the display application activated in step S25 (step S29). By performing the parameter delivery process as described above, the content identified by the content identification information is displayed by the display application, as in the example of FIG.

[1-5] Effects of First Embodiment A communication terminal having a communication function is often preinstalled with a browser (installed in advance at the time of sale) in order to access content on the Internet. In the present embodiment, a parameter delivery instruction is issued from the server device 10 to the browser of the communication terminal 20, and parameters are passed to the application executed by the communication terminal 20 via the browser. For this reason, most users who use the communication terminal do not have the trouble of preparing an environment for passing parameters to the program (for example, the trouble of installing a specific program).

  In the present embodiment, in response to an installation instruction from the server device 10, the application is automatically installed on the communication terminal 20 in which no application is installed. Thereby, compared with the case where a user installs an application manually, a user's effort can be reduced. In addition, when manual installation is required, an application may not be installed in the communication terminal 20 of the user who takes time and effort, but in the present embodiment, the application is also installed in such a communication terminal 20. Therefore, the number of communication terminals 20 on which the application is executed can be increased.

  When an application is installed as described above, in order to pass parameters to the application in which the communication terminal is installed, for example, the parameters included in the medium description information read before installation by some program function are retained until after installation. There is a way to do it. However, in order to perform this method, for example, it is necessary to add a function for holding such parameters to a reading program or a browser, or to install a program for realizing the function separately.

  In the present embodiment, the parameters stored in the server device 10 before the application is installed are provided to the communication terminal 20 after the application is installed and passed to the application. Thereby, even if it is a communication terminal which does not have the function to hold | maintain a parameter before and after installation of an application, a parameter can be passed to the application after installation. Further, in the present embodiment, by using a browser for exchanging parameters between the server device 10 and the communication terminal 20, the server device 10 is the same before and after the application installation based on the terminal identification information stored in the cookie. The communication terminal 20 can be identified.

[2] Second Embodiment Hereinafter, a second embodiment of the present invention will be described focusing on differences from the first embodiment. In the first embodiment, the server device identifies the communication terminal based on the terminal identification information. In the second embodiment, the server terminal identifies the communication terminal based on other information obtained by communication with the browser of the communication terminal. .

[2-1] Functional Configuration FIG. 8 is a diagram illustrating an example of a functional configuration of the server device according to the second embodiment. In FIG. 8, a server device 10 a including an acquisition unit 105 in addition to the units illustrated in FIG. 4 is illustrated.
The acquisition unit 105 is an example of a unit that acquires the IP (Internet Protocol) address of the communication terminal 20 and the attribute of the browser executed in the communication terminal 20 from the communication terminal 20. The acquisition unit 105 acquires, for example, the IP address of the transmission source included in the header of the packet transmitted in step S14 illustrated in FIG. 6 as the IP address of the communication terminal 20.

  The acquisition unit 105 acquires, for example, a browser type (for example, represented by a browser name) and a browser version as browser attributes. Specifically, the acquisition unit 105 describes, for example, Javascript that notifies the local device of the browser type and version of the communication terminal 20 in the HTTP response transmitted in step S16 illustrated in FIG. Upon receiving this HTTP response, the communication terminal 20 executes the described JavaScript and notifies the server device 10a of the browser type and version of its own device. The acquisition unit 105 acquires the browser type and version thus notified as browser attributes. The acquisition unit 105 supplies the acquired data indicating the acquired IP address and browser attribute to the storage unit 102 and the first instruction unit 103.

The storage unit 102 stores the parameters received by the receiving unit 101 in association with the IP address and browser attributes acquired by the acquiring unit 105. Specifically, for example, the storage unit 102 stores the IP address and the browser attribute indicated by the acquisition data supplied from the acquisition unit 105 when each parameter shown in FIG. 5 is stored, in the terminal identification information table. Store in a row.
FIG. 9 is a diagram illustrating an example of a terminal identification information table according to the present embodiment. In the example of FIG. 9, IP addresses “xxx.... Xxx” and “yyy. The browser attributes “v8.1” and “B browser v9.1” are stored.

  In the present embodiment, the first instruction unit 103 receives the application identification information stored in the storage unit 102 after the application is installed in the communication terminal 20 according to the instruction from the second instruction unit 104. If the terminal identification information is not received, an instruction different from that in the first embodiment is given. Specifically, the first instruction unit 103 stores the browser executed in the communication terminal 20 in the storage unit 102 in association with the IP address and the browser attribute acquired by the acquisition unit 105 for the communication terminal 20. Instructs the app to pass the stored parameters to the app.

  For example, when the receiving means 101 receives the application identification information “APP — 001”, in the example of FIG. 9, the parameters associated with this application identification information in the terminal identification information table are 2 of “CONTENTS — 01” and “CONTENTS — 02”. There is one. Here, when the acquisition unit 105 acquires the IP address “yyy... Yyy” and the browser attribute “B browser v9.1”, the first instruction unit 103 stores these in the terminal identification information table. The parameter delivery instruction is performed so that “CONTENTS — 02”, which is the parameter associated with, is passed to the application.

[2-2] Effects according to the second embodiment When the server device identifies the communication terminal based on the terminal identification information stored in the cookie, the cookie is deleted or the use of the cookie is not permitted in the browser setting. The communication terminal may not be identified. In this embodiment, since the communication terminal is identified based on the IP address and the browser attribute, even when the communication terminal cannot be identified based on the cookie, the server apparatus 10 identifies the same communication terminal 20 before and after installing the application. be able to.

  In the present embodiment, both the application identification information and the terminal identification information may be received after the application is installed in the communication terminal 20. In that case, the first instruction unit 103 may perform the parameter delivery instruction described in the first embodiment, or may perform the parameter delivery instruction described in the second embodiment.
