Description

  The present invention relates to a communication terminal, a connection method, and a program.

  In recent years, efforts to provide various multimedia services to communication terminals such as mobile phones have been actively performed. In order to cope with such diversified multimedia services, communication terminals have also been increased in speed and functionality. For this reason, in a communication system that provides a communication service (including a multimedia service) to the communication terminal, a large amount of data is often communicated.

  In addition, there are two typical charge plans for receiving communication service provision in a general communication system that performs multimedia services as described above, namely “pay-for-use charge” and “fixed charge”. Further, in a terminal capable of using both circuit switching and packet switching communication, packet switching using pay-per-use or flat-rate charging when the communication volume such as the number of packets performed by the communication terminal exceeds a threshold value A technique for changing from a video transmission service based on the above to a video transmission service based on circuit switching using pay-per-use is also considered (for example, see Patent Document 1).

  The “pay-as-you-go billing” described above is a rate plan in which a charge is imposed on the user according to the amount of data or time communicated by the communication terminal during a predetermined period. For this reason, pay-per-use has a problem that when a user mistakenly performs large-capacity data communication, a high charge unintended by the user is charged.

  In order to make it difficult to cause such problems in pay-per-use billing, when starting communication, a confirmation screen for confirming whether or not to allow communication is displayed and communication may be performed. A technique for starting communication when an input is made by a user is widely used.

On the other hand, “Flat-rate billing” is a rate plan in which a fixed amount of charge is imposed on the user regardless of the amount of data communicated by the communication terminal during a predetermined period. For this reason, even if the user makes a large amount of data communication by mistake, only a fixed amount is charged. Therefore, a user with a fixed charge can communicate with a communication terminal without paying attention to the problem of a large charge due to an erroneous operation.
JP 2006-050594 A

  However, a general communication terminal is configured based on a specification that assumes a user who is contracted for pay-per-use.

  For this reason, when a user who subscribes to a flat-rate billing tries to start communication using a communication terminal, the confirmation screen is displayed each time, although it is not necessary to display the confirmation screen. Therefore, in such a communication terminal, there is a problem that a user who has contracted for a flat fee cannot start communication smoothly.

  An object of this invention is to provide the communication terminal, the connection method, and program which solve the subject mentioned above.

  In order to solve the above problems, the communication terminal of the present invention displays a confirmation screen to confirm whether or not to connect to the connection destination when receiving an input specifying the connection destination from the user. If the charging method for the communication of the communication terminal is fixed rate charging, the confirmation screen is not displayed and the connection destination is connected.

  In order to solve the above-described problem, the connection method of the present invention is configured such that when a communication terminal accepts an input for specifying a connection destination from a user, the communication method for the communication terminal is either metered charge or fixed charge. A process for displaying a confirmation screen for confirming whether or not to connect to the connection destination when it is determined that the charging method is a flat-rate charge, and the confirmation screen A process for connecting to the connection destination when the user accepts an input for connecting to the connection destination from the user, or when the charging method is determined to be a flat-rate charge. .

  In addition, a program to be executed by a computer, and when a communication terminal receives an input for designating a connection destination from a user, whether the charging method for communication of the communication terminal is pay-per-use or flat-rate charging And a procedure for displaying a confirmation screen for confirming whether or not to connect to the connection destination when it is determined that the charging method is a flat fee, and When the user receives an input for connecting to the connection destination from the user, or when it is determined that the charging method is a flat-rate charging, a procedure for connecting to the connection destination is executed.

  According to the present invention, when an input specifying a connection destination is received from a user, a communication terminal that displays a confirmation screen to confirm whether or not to connect to the connection destination is If the billing method for communication is flat-rate billing, the confirmation screen is not displayed and the connection destination is connected.

  With such a configuration, a user who has contracted with a flat-rate billing can easily connect a communication terminal and a desired connection destination.

(Embodiment 1)
Hereinafter, a communication system (including a communication terminal, a connection method, and a program) according to the first embodiment of the present invention will be described.

  First, the overall configuration of the communication system according to the first embodiment will be described.

  As shown in FIG. 1, the communication system includes a communication terminal 1 and a contract information management server 2. Here, the number of communication terminals 1 is not limited.

  When the communication terminal 1 accepts an input specifying an arbitrary “connection destination (not shown)” from the user, the communication terminal 1 can communicate with the connection destination.

  The contract information management server 2 is, for example, a server managed by a carrier that provides a communication service in the communication system, and stores contract information CTR indicating a charging method for communication of the communication terminal 1.

  Examples of the “charging method” here include “fixed amount charging” in which a fixed amount is charged regardless of the amount of data communicated by the user using the communication terminal 1 within a predetermined period, and usage within a predetermined period. “Pay-as-you-go billing” is included in which billing is performed according to the amount and time of data communicated by the person using the communication terminal 1.

  By communicating between the communication terminal 1 and the contract information management server 2, the communication terminal 1 can acquire the contract information CTR of the user who uses the communication terminal 1.

  Next, the configuration of the communication terminal 1 shown in FIG. 1 will be described in detail.

  As illustrated in FIG. 2, the communication terminal 1 includes an input unit 11, a communication unit 12, a control unit 13, and a display unit 14.

  The input unit 11 accepts an input operation performed by the user and outputs various signals corresponding to the input operation to the control unit 13.

  For example, the input unit 11 receives an input designating a connection destination (not shown) from the user.

  Further, the input unit 11 outputs a communication start instruction according to the input operation performed by the user to the control unit 13.

  The “communication start instruction” here is a signal instructing to connect to the connection destination using the communication unit 12 and start communication.

  Further, the input unit 11 outputs a communication execution confirmation and a communication stop confirmation according to the input operation performed by the user to the control unit 13.

  Here, “communication execution confirmation” is a signal instructing to execute communication instructed to start by connecting to a connection destination according to a communication start instruction.

  The “communication stop confirmation” is a signal instructing to stop the communication instructed to start by connecting to the destination according to the communication start instruction.

  The communication unit 12 is, for example, a wireless communication module, and transmits / receives arbitrary data via a network.

  For example, the communication unit 12 receives the contract information CTR from the contract information management server 2.

  The contract information CTR is “pay-as-you-go” in which a fee is charged according to the amount of data communicated by a user using the communication terminal 1 within a predetermined period, and the user communicates within a predetermined period using the communication terminal 1. This is information indicating whether it is “fixed amount charging” in which a fixed amount is charged regardless of the amount of data.

  The control unit 13 controls the operation of the entire communication terminal 1.

  As illustrated in FIG. 3, the control unit 13 includes a contract determination unit 131, a data determination unit 132, and a communication instruction unit 133.

  When the input unit 11 receives an input of a communication start instruction from the user, the contract determination unit 131 outputs an “acquisition instruction” for acquiring the contract information CTR from the contract information management server 2 to the communication unit 12. To do.

  Further, the contract determination unit 131 determines whether the charging method for communication of the communication terminal 1 is “pay-as-you-go” or “flat-rate charging” based on the contract information CTR acquired by the communication unit 12 according to the acquisition instruction. To do.

  The data determination unit 132 stores data that can be displayed by the display unit 14. Further, the data determination unit 132 determines data to be displayed on the display unit 14 from the stored data, and outputs the determined data to the display unit 14.

  For example, when the contract determining unit 131 determines that the charging method for communication of the communication terminal 1 is “pay-as-you-go”, the data determining unit 132 determines the data to be displayed on the display unit 14 on the confirmation screen CFM. Then, the data determination unit 132 outputs the data of the determined confirmation screen CFM to the display unit 14.

  As shown in FIG. 4, the confirmation screen CFM is a screen for confirming to the user whether or not the communication requested to be started is actually performed by connecting to the connection destination according to the communication start instruction.

  Further, the data determination unit 132 determines the communication execution screen CMN shown in FIG. 5 as data to be displayed on the display unit 14 while the communication unit 12 is executing the communication instructed by the communication execution instruction. The communication execution screen CMN is a screen for indicating that the communication unit 12 is executing communication that has been confirmed by the user to be executed.

  The communication instruction unit 133 instructs the communication unit 12 to connect to and communicate with the connection destination instructed by the user when the contract determination unit 131 determines that the charge is flat rate.

  Further, when an input for selecting “YES” from the selection branches (YES and NO) displayed on the confirmation screen CFM is received from the user, the input unit 11 outputs a communication execution confirmation to the communication instruction unit 133. To do. When a communication execution confirmation is output from the input unit 11, the communication instruction unit 133 instructs the communication unit 12 to perform communication instructed by the user.

  Further, when an input for selecting “NO” from the selection branches (YES and NO) displayed on the confirmation screen CFM is received from the user, the input unit 11 outputs a communication stop confirmation to the communication instruction unit 133. To do. When a communication cancellation confirmation is output from the input unit 11, the communication instruction unit 133 does not issue a communication execution instruction to the communication unit 12. In this example, when a communication stop confirmation is output from the input unit 11, the communication instruction unit 133 instructs the data determination unit 132 to determine data to be displayed on the display unit 14. In accordance with the instruction, the data determination unit 132 determines, for example, the electronic mail EM illustrated in FIG. 6 as data to be displayed on the display unit 14.

  The display unit 14 shown in FIG. 2 is an LCD (liquid crystal display) panel, for example, and displays arbitrary data.

  For example, the display unit 14 displays data (e-mail EM, confirmation screen CFM, communication execution screen CMN, etc.) determined and output by the data determination unit 132.

  Next, in the communication system according to the first embodiment having the above-described configuration, an operation in which the communication terminal 1 executes communication according to a charging method for communication of the communication terminal 1 will be described with reference to a flowchart shown in FIG.

  First, in step 31, the contract discrimination unit 131 discriminates whether or not a function necessary for communication is activated by an operation of the input unit 11 performed by the user and a communication start instruction is issued.

  Here, “function activation” means “http: //URL.URL.” Which is a URL (Uniform Resource Locator) displayed in the e-mail shown in FIG. 6 when the user operates the input unit 11. "com" is specified, and the browser is started, and an operation for instructing communication start with respect to the connection destination indicated by the URL is applicable.

  When it is determined that the communication start instruction has been performed in step 31, the contract determination unit 131 outputs an acquisition instruction for instructing acquisition of the contract information CTR from the contract information management server 2 to the communication unit 12.

  Thereafter, in step 32, the communication unit 12 acquires the contract information CTR from the contract information management server 2 in accordance with the acquisition instruction.

  Further, in step 33, based on the contract information CTR received by the communication unit 12, the contract determination unit 131 determines whether the billing method for communication of the communication terminal 1 is “pay-as-you-go” or “flat-rate billing”. Is determined.

  If it is determined in step 33 that the charging method is “fixed charge”, the contract determining unit 131 notifies the communication instruction unit 133 that the charge method is fixed charge. Then, the communication instruction unit 133 outputs to the communication unit 12 a communication execution instruction that instructs execution of the communication requested to be started by the communication start instruction.

  If a communication execution instruction is output from the communication instruction unit 133, in step 34, the communication unit 12 immediately executes the communication instructed to start communication. While the communication unit 12 is executing the communication, the display unit 14 displays the communication execution screen CMN illustrated in FIG.

  On the other hand, when it is determined in step 33 that the charging method is “pay-as-you-go”, the contract determination unit 131 notifies the data determining unit 132 that the charging method is pay-as-you-go. Then, the data determination unit 132 determines, as data to be displayed on the display unit 14, a confirmation screen CFM for confirming to the user whether or not the communication requested to connect to and start the connection destination can be executed. In step 35, the display unit 14 displays the confirmation screen CFM determined by the data determination unit 132.

  Thereafter, when the communication instruction unit 133 accepts the input of the communication execution confirmation to the input unit 11 by the user in step 36, the communication instruction unit 133 notifies the communication unit 12 to perform communication requested to start by the communication start instruction. Instruct. The case where the communication execution confirmation input is accepted means that the input unit 11 accepts an input for selecting “YES” from the selection branch (YES or NO) displayed on the confirmation screen CFM. It is.

  Subsequently, in step 34, the communication unit 12 executes communication instructed by the user. While the communication unit 12 is executing the communication, the display unit 14 displays the communication execution screen CMN illustrated in FIG.

Further, when the communication instruction unit 133 receives an input of confirmation of communication stoppage to the input unit 11 by the user in step 36, the communication instruction unit 133 does not issue a communication instruction to the communication unit 12. In addition, the case where the input of communication cancellation confirmation is received means the case where the input unit 11 receives an input for selecting “NO” from the selection branches (YES or NO) displayed on the confirmation screen CFM. It is.
In this example, the communication instruction unit 133 instructs the data determination unit 132 to determine data to be displayed on the display unit 14. When the instruction is given, the data determining unit 132 determines the email EM shown in FIG. 6 as data to be displayed on the display unit 14.

  With the above, a series of operations in which the communication terminal 1 according to the first embodiment performs communication according to the charging method for communication of the communication terminal 1 is completed.

  As described above, according to the first embodiment of the present invention, the communication terminal 1 acquires the contract information CTR from the contract information management server 2 when the user instructs the start of communication. Then, the communication terminal 1 determines whether the billing method for the communication of the communication terminal 1 indicated by the acquired contract information CTR is metered charge or fixed charge. When it is determined that the charge is a flat fee, the communication terminal 1 immediately executes communication instructed by the user.

  Further, when it is determined that the usage fee is charged, the communication terminal 1 displays a confirmation screen CFM for confirming whether to communicate by connecting to the connection destination. Then, when it is confirmed that the user performs communication via the confirmation screen CFM, communication instructed by the user is executed.

  As a result, when a user who subscribes to “Flat-rate billing” communicates using the communication terminal 1, the confirmation screen CFM for the pay-per-use subscriber who is unrelated to the user is not displayed. The communication terminal 1 and a desired connection destination (not shown) can be easily connected.

  Further, according to the first embodiment, when a user who has contracted “pay-for-use billing” performs communication using the communication terminal 1, the confirmation screen CFM is displayed prior to the execution of the communication. As a result, it is possible to make it difficult for a user who subscribes to pay-per-use to accidentally transmit a large amount of data.

(Embodiment 2)
In Embodiment 1 described above, the communication terminal 1 determines whether or not to display the confirmation screen CFM based on the contract information CTR acquired from the contract information management server 2.

  However, the usage method of the contract information CTR is not limited to the determination of whether or not the confirmation screen CFM is displayed. For example, the contract information CTR is used to change the configuration of the menu screen indicating the function that is associated with the execution of communication. It is also possible.

  Hereinafter, the communication system of Embodiment 2 which performs such operation | movement is demonstrated.

  As shown in FIG. 8, the communication system of the second embodiment is different from the communication system of the first embodiment in that a communication terminal 1A is provided instead of the communication terminal 1 shown in FIG.

  In the following, when using a predetermined function of the communication terminal 1A, the user activates a menu screen including a list of the functions by an operation using the input unit 11 of the communication terminal 1A. An example will be described in which the function to be used is selected from those displayed in.

  Next, the configuration of the communication terminal 1A according to the second embodiment will be described.

  As illustrated in FIG. 9, the communication terminal 1A is different from the communication terminal 1 of the first embodiment in that the communication terminal 1A includes a control unit 13A instead of the control unit 13 illustrated in FIG.

  As illustrated in FIG. 10, the control unit 13 </ b> A includes an activation determination unit 134 and a restricted menu generation unit 135 in addition to the components of the control unit 13 illustrated in FIG. 3.

  The activation determination unit 134 determines whether the input unit 11 has received an input from the user of an activation instruction for activating the “menu screen” for function selection.

  Here, the “menu screen” refers to a communication amount unrestricted menu screen ULM (hereinafter referred to as “unrestricted menu screen ULM”) and a communication amount restriction menu screen LMT (hereinafter referred to as “restricted menu screen LMT”). Either one.

  As shown in FIG. 11, the unrestricted menu screen ULM is a screen showing functions that can be used by the user using the communication terminal 1 regardless of the amount of communication that occurs when the functions of the communication terminal 1 are used. It is.

  In this example, the data determination unit 132 stores the data of the unrestricted menu screen ULM.

  Also, as shown in FIG. 12, the restricted menu screen LMT shows only the functions whose communication amount when using the function is equal to or less than a predetermined value among the functions included in the unrestricted menu screen ULM. It is a screen.

  In other words, the restricted menu screen LMT excludes a function that causes the amount of communication when the function is used to be larger than a predetermined value from the functions included in the unrestricted menu screen ULM. More specifically, “2, full browser”, “4, PC video”, and “5, video distribution” among the functions included in the unrestricted menu screen ULM shown in FIG. This is a function that generates a larger amount of communication than a predetermined value when each function is used. Therefore, these functions are excluded from the restricted menu screen LMT shown in FIG.

  In the second embodiment, the contract determination unit 131 illustrated in FIG. 10 outputs an acquisition instruction to the communication unit 12 when the start determination unit 134 determines that a start instruction has been issued. Thereafter, the contract determination unit 131 determines whether the charging method for communication of the communication terminal 1 is “pay-as-you-go” or “flat-rate charging” based on the contract information CTR acquired by the communication unit 12 according to the acquisition instruction. To do.

  The restriction menu generation unit 135 generates a restriction menu screen LMT when the contract determination unit 131 determines that the charging method is “pay-as-you-go”.

  In this example, the restriction menu generation unit 135 stores the communication amount restriction target information OBJ illustrated in FIG. Here, the traffic volume restriction target information OBJ is information in which each function for which the traffic volume when the function is used becomes larger than a predetermined value is stored.

  When the contract determining unit 131 determines that the charge is based, the restricted menu generating unit 135 acquires the data of the unrestricted menu screen ULM stored in the data determining unit 132. Subsequently, the restricted menu generating unit 135 specifies a function stored in the traffic restriction target information OBJ from among the functions included in the acquired unrestricted menu screen ULM. Then, the restricted menu screen LMT is generated by excluding the specified function and generating a screen including only functions other than the specified function.

  Next, the communication terminal 1A displays either the unrestricted menu screen ULM or the restricted menu screen LMT according to the charging method for the communication of the communication terminal 1, and the unrestricted menu screen ULM or the restricted menu screen LMT. The operation for performing communication corresponding to the function selected from the above will be described with reference to the flowchart shown in FIG.

  First, in step 41, the activation determination unit 134 determines whether or not the input unit 11 has received an input of an activation instruction for a menu screen (unrestricted menu screen ULM or restricted menu screen LMT) from the user.

  When the activation determination unit 134 determines that the menu screen activation instruction has been received, the contract identification unit 131 instructs the communication unit 12 to acquire the contract information CTR from the contract information management server 2. Is output.

  In step 42, the communication unit 12 acquires the contract information CTR from the contract information management server 2 in accordance with the acquisition instruction output from the contract determination unit 131.

  Thereafter, in step 43, the contract determination unit 131 determines whether the charging method for communication of the communication terminal 1 is “pay-as-you-go” or “flat-rate charging” based on the contract information CTR acquired by the communication unit 12. Is determined.

  When the contract determination unit 131 determines that the charging method is “Flat-rate charging” in step 43, the data determination unit 132 determines the data to be displayed on the display unit 14 as the unrestricted menu screen ULM for fixed-rate charging. . Subsequently, the data determination unit 132 outputs the determined unrestricted menu screen ULM to the display unit 14.

  In step 44, the display unit 14 displays the unrestricted menu screen ULM output from the data determination unit 132.

  Thereafter, in step 45, when the function selected by the user using the input unit 11 from the unrestricted menu screen ULM is executed, the communication unit 12 executes communication corresponding to the function. To do.

  For example, when “5, video distribution” is selected by the user from the unrestricted menu screen ULM illustrated in FIG. 11, communication associated with the execution of the video distribution is executed.

  Note that the communication processing of the communication unit 12 in step 45 may be executed according to step 31 and steps 33 to 36 shown in FIG. In this case, in step 33, the contract determination unit 131 may determine the content of the user's contract using the contract information CTR acquired by the communication unit 12 in step 42.

  On the other hand, when the contract determination unit 131 determines that the charging method is “pay-as-you-go” in step 43, the restriction menu generation unit 135 determines in step 46 that the restriction menu for users who have contracted pay-per-use. A screen LMT is generated. In this example, the restricted menu generating unit 135 first acquires data of the unrestricted menu screen ULM stored in the data determining unit 132. Subsequently, the restricted menu generating unit 135 specifies a function stored in the traffic restriction target information OBJ from among the functions included in the acquired unrestricted menu screen ULM. Then, the restricted menu screen LMT is generated by excluding the specified function and generating a screen including only functions other than the specified function.

  Subsequently, the restriction menu generation unit 135 outputs the generated restriction menu screen LMT to the display unit 14.

  In step 47, display unit 14 displays restriction menu screen LMT output from restriction menu generation unit 135. By performing the display, a user who has contracted with a pay-per-use charge selects and executes a function for performing a large amount of data communication from the menu screen displayed on the display unit 14, which is expensive. It is possible to make it difficult to generate a large fee.

  After that, in step 45, when the function selected by the user using the input unit 11 from among those included in the restricted menu screen LMT is executed, the communication unit 12 executes communication corresponding to the function. .

  Various modifications can be made without departing from the scope of the present invention.

  The communication unit 12 is not limited to acquiring the contract information CTR from the contract information management server 2 every time a communication start instruction or a menu screen activation instruction is performed by an operation of the input unit 11 performed by the user. For example, the contract information CTR once acquired by the communication unit 12 may be stored in the communication terminal 1, and the billing method may be determined using the stored contract information CTR. This eliminates the need to execute the process for obtaining the contract information CTR when the second or subsequent communication start instruction or activation instruction is issued.

  In the present invention, the processing in the communication terminal 1 is recorded on a recording medium readable by the communication terminal 1 in addition to the above-described dedicated hardware. The program recorded in the recording medium may be read by the communication terminal 1 and executed. The recording medium readable by the communication terminal 1 refers to a HDD or the like built in the communication terminal 1 in addition to a transferable recording medium such as a floppy disk (registered trademark), a magneto-optical disk, a DVD, or a CD. For example, the program recorded in the recording medium is read by the control unit 13 included in the communication terminal 1, and the same processing as described above is performed under the control of the control unit 13.

  Here, the control unit 13 included in the communication terminal 1 operates as a computer that executes a program read from a recording medium on which the program is recorded.

  The program described above can be similarly applied to the communication terminal 1A.

  Although the present invention has been described with reference to the first and second embodiments, the present invention is not limited to the first and second embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention without departing from the gist of the present invention.
