Description

  The present invention relates to a technique for assigning another function to an operator for requesting a service provided by a communication carrier via a communication network by a contract in a standby state.

  Mobile communication terminal devices represented by mobile phones and PHS (hereinafter abbreviated as “communication terminals”) are now widely used in society. In recent years, the communication terminal has been equipped with various functions due to advances in semiconductor technology. As a result, it is now used in a wide range of applications.

  Such a communication terminal is assumed to be carried and used. For this reason, portability is emphasized. The number of controls such as switches is usually kept to a minimum in order to avoid an increase in size. As a result, the ratio of the operators that dynamically change the function assigned according to the operation state is large.

  Functions that are considered to be used by users relatively frequently among the installed functions are usually not in communication and can be easily activated from a standby state in which no functions are activated. A function for requesting activation of the function is fixedly assigned to one of the operators. Activation of other functions is performed by displaying the corresponding menu screen and selecting it on the screen.

  Among the functions that can be activated by operating such an operator, there is usually a service for a service provided by a telecommunications carrier through a contract. The service is, for example, a data communication service that enables connection to the Internet.

  However, the purchaser (user) of the communication terminal does not necessarily make a contract for all services provided by the communication carrier. This means that, among the operators assigned with functions for requesting activation of the function for the service, the purchaser actually has no function assigned thereto. From this, it is thought that giving a different function to such an operator should be emphasized from the viewpoint of improving the operability.

Some conventional communication terminals, for example, as described in Patent Document 1, invalidate a function assigned in a standby state depending on an operation mode. The communication terminal described in Patent Document 1 has an operation mode in which an incoming call is not accepted unless a predetermined condition is satisfied, and a calling operation is prohibited in the operation mode.

  An object of the present invention is to provide a communication terminal device that can more effectively utilize an operator for requesting activation of a function for a service when there is a service that is not contracted among services provided by a communication carrier. Is to provide.

  The communication terminal device of the present invention is based on the premise that a service request function for requesting a service provided by a communication carrier via a communication network by a contract is provided in advance in a standby state, with an operator assigned beforehand. Service processing means for performing processing for providing a service performed by a communication carrier via a communication network, and control means for causing the service processing means to make a service request by operating an operator assigned a service request function And an assignment management means for enabling assignment of other functions to the operator when there is a response indicating that the service is not provided from the telecommunications carrier side by causing the service processing means to perform a service request. When the function can be assigned by the assignment management means, the operator is assigned to the operator according to the operation to the predetermined operator. A function assigning means for assigning a function, comprising a.

  Note that the above-mentioned assignment management means makes it possible to immediately assign another function to the operator when there is a response from the telecommunications carrier side that the service is not provided, and to assign it to the operator by the function assignment means. It is desirable to let the user select the function.

  The program of the present invention has a function for realizing the communication terminal apparatus of the present invention.

  According to the present invention, a service is requested by an operation to an operator to which a service request function for requesting a service provided via a communication network by a telecommunications carrier is assigned, and thereby a service is provided from the telecommunications carrier If there is a response not to provide the user, the user is assigned another function to the operator. By performing the assignment, the operator assigned the service request function can be customized so as to be easy to use. Originally, the assigned service request function does not actually function, so that the operability is not lowered by the customization. For these reasons, the operator can be used more effectively, and the communication terminal device can be used more comfortably.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a configuration diagram of a communication terminal apparatus according to the present embodiment. The communication terminal device 1 is an application of the present invention to a mobile communication terminal device such as a mobile phone or a PHS. Here, for the sake of convenience, it is assumed to be a mobile phone and will be referred to as “communication terminal”.

  As shown in FIG. 1, the communication terminal 1 controls a radio frequency (RF) unit 101 for a mobile phone that performs frequency conversion, modulation / demodulation, and the like of a radio signal transmitted and received via an antenna AT1, and controls the entire terminal. CPU 102, program ROM 103 storing programs executed by CPU 102 and various control data, work RAM 104 used by CPU 102 for work, two display units 105 and 106, both of which are liquid crystal display devices, for example, and each display unit Display driver unit 107 for displaying images on 105 and 106, microphone 108 for sound input, speaker 109 for sound emission, operation unit 110 having various switches, and AC for receiving current from the outside Adapter 111, rechargeable battery (battery) 112, and power supply circuit for supplying current to each unit And it is configured to include a 13.

  Although not particularly illustrated, an analog audio signal output from the microphone 108 is converted into a digital audio signal by an A / D converter and then output to the CPU 102 or the RF unit 101. In addition, an analog audio signal converted by the D / A converter is output to the speaker 109 and an unillustrated earphone jack.

  The two display units 105 and 106 have different screen sizes. The screen of the display unit 105 is larger. Therefore, the display unit 105 is called a main display unit, and the display unit 106 is called a sub display unit.

  The RF unit 101 receives and processes a signal transmitted from a mobile phone network. The received signal is demodulated and output to the CPU 102, the speaker 109, and a jack (hereinafter, only the former is assumed). At the time of a telephone call, the signal is output to the speaker 109 to emit sound from the connection destination (the telephone connected to the telephone). The audio signal from the microphone 108 is modulated and transmitted via the antenna AT1. When connected to the Internet, the demodulated signal (digital data) is output to the CPU 102. Data from the CPU 102 is modulated and transmitted via the antenna AT1.

The operation unit 110 includes various switches (see FIG. 2) to be operated by the user, and a detection circuit that detects operations performed on the various switches by the user.
The power supply circuit 113 monitors each output of the AC adapter 111 and the rechargeable battery 112. Thereby, it is determined whether or not current is supplied to the AC adapter 111 from an external power source (for example, an outlet), and the CPU 102 is notified of the determination result. The rechargeable battery 112 detects the voltage value and notifies the CPU 102 of it.

FIG. 2 is an external view of the communication terminal 1.
As shown in FIG. 2, the communication terminal 1 is of a folding type, and the main display unit 105 is disposed on the inner side when folded. Inside, in addition to the main display unit 105, the earpiece 201 in which the speaker 109 is provided, the determination switch 202, the cursor switch 203, the function switch 204, and the mail function arranged around it are activated. A mail switch 205, an off-hook switch 206, a plurality of dial keys 207, a switching key 208, an address book switch 209, an EZ switch 210 for activating a data communication function for realizing connection to the Internet, a clear switch 211, an on-hook switch 212, A # key 213 and a microphone 108 are arranged. Among these, the switches 202 to 213 constitute the operation unit 110.

  When the carrier of the cellular phone network to which the communication terminal 1 is connected is only for users who have contracted the data communication service, the data communication function for receiving the service cannot be practically used without a contract. . If the communication function cannot be used, the functions of the EZ switch 210 and the mail switch 205 are not substantially assigned in the standby state in which the standby screen is displayed. For this reason, in this embodiment, when the user does not contract the data communication service, arbitrary functions can be assigned to the EZ switch 210 and the mail switch 205, respectively. As a result, a desired function can be assigned so as to be easy for the user to use, and the switches 205 and 210 can be used more effectively. As a result, since the operability is improved, the communication terminal 1 can be used more comfortably.

  Hereinafter, the operation of the communication terminal 1 that realizes the assignment of the functions will be described in detail with reference to the flowcharts of the processes illustrated in FIGS. 3 to 9 and the explanatory diagram illustrated in FIG. 10. Each process illustrated in FIGS. 3 to 9 is realized by the CPU 102 executing a program stored in the program ROM 103, for example.

  3 to 7 are flowcharts of the entire process. It shows an excerpt of the overall flow of processing executed after the power is turned on. First, the entire process will be described in detail with reference to FIGS.

  First, in step 101, initialization is executed when the power is turned on, and the communication terminal 1 is set to a predetermined setting state. In the subsequent step 102, for example, the standby screen read from the program ROM 108 is stored in the drawing area secured in the work RAM 104, and the screen is sent to the display driver unit 107 to be displayed on the main display unit 105. Similarly, the sub display unit 106 displays a standby screen. Thereafter, the process proceeds to step 103 to determine whether or not the off-hook switch 206 is turned on. When the switch 206 is operated by the user, the fact is notified from the operation unit 110 to the CPU 102, so that the determination is YES and the process proceeds to step 104. Otherwise, the determination is no and the process moves to step 112 in FIG.

  The screens displayed on the display units 105 and 106 include, for example, image data (screens and symbols) read from the program ROM 103 or image data sent from the RF unit 101 in a drawing area secured in the work RAM 104. Generated by storing. The change of the display contents is realized by sending all or part of the display contents to the display driver unit 107 and displaying them.

  In step 104, a number input screen for inputting a telephone number is displayed on the main display unit 105. In the next step 105, the number input by the number input operation (operation on the dial key 207) on the operation unit 110 is displayed on the main display unit 105. In step 106 where the input operation is not performed for a certain period of time, for example, connection with a telephone having a telephone number input by the user (hereinafter referred to as “connection destination” or “partner machine”) is performed. Make a call to request.

  By the above transmission, the mobile phone network side performs a process for calling the designated partner machine, and the calling side performs a process for emitting a ringing sound to notify that. Therefore, in step 107 following step 106, a ringing tone is emitted in accordance with an instruction from the mobile phone network side. The sound emission is performed until the determination in the next step 108 becomes YES by connecting to the partner machine. The process proceeds to step 109 with a YES determination.

  Note that the above transmission is performed, for example, when the CPU 102 sends necessary information to the RF unit 101 and instructs it. The ringing tone is emitted when the RF signal is received by the RF unit 101 and demodulated, and the demodulated signal is output to the speaker 109 directly or via the CPU 102.

  If the other party is busy or the telephone cannot be placed because the power is off, a signal to that effect is transmitted from the mobile phone network side. The call of the other party is terminated when the user instructs to stop the transmission. For this reason, it is not always possible to connect to the other device by making an outgoing call. However, since this is not particularly important, it is omitted here. The same applies to other cases.

  In step 109, a call process for realizing a call by exchanging audio signals with the partner machine is executed. In the next step 110, it is determined whether or not the on-hook switch 212 is turned on. If the switch 212 is operated by the user, the determination is yes, and after disconnecting the connection with the other device, that is, executing the call termination process for requesting the call to the mobile phone network side in step 111, the process returns to step 102 above. The standby screen is displayed on the main display unit 105. Otherwise, the determination is no and the process returns to step 109 above. As a result, a state in which a call can be made is maintained until the end of the call is requested.

  In step 112 of FIG. 4 in which the determination in step 103 is NO and the process proceeds, it is determined whether or not the function switch 204 is turned on. If the user operates the switch 204, the determination is yes and the process proceeds to step 113. If not, the determination is no and the process proceeds to step 122 in FIG.

  The function switch 204 is for starting a setting function related to various functions. The function assigned by the user to the switches 205 and 210 can be released (reset) by operating the switch 204 to activate the setting function. Steps 113 to 121 are executed in order to realize the setting function.

  First, in step 113, a function list screen on which settable items are arranged is displayed on the main display unit 105. In the following step 114, one item on the list is focused and selected. In the next step 115, it is determined whether or not the cursor switch 203 is turned on. If the user operates the switch 203, the determination is YES, and the process of moving the focus position according to the type of switch operated by the user in the switch 203 and the position of the focused item is executed in step 116. Then, the process proceeds to step 117. Otherwise, the determination is no and the process moves to step 117.

  In step 117, it is determined whether or not the decision switch 202 is turned on. If the user operates the switch 202, the determination is yes and the process moves to step 119. Otherwise, the determination is no and the process moves to step 118 to determine whether or not the clear switch 211 is turned on. If the user operates the switch 211, the determination is yes and the process returns to step 102 in FIG. Otherwise, the determination is no and the process returns to step 115 above. As a result, until the user operates the clear switch 211 or the determination switch 202, a state in which an item to be set can be selected by operating the cursor switch 203 is maintained.

  In step 119, it is determined whether or not the item of the focus position is “reset”. The item is used to request the switch 205, 210 to release the function assigned by the user, that is, to assign a function assigned in advance. From this, when the user requests to release the assigned function, the determination is YES, and the reset process for performing the release is executed in step 120 and then the process returns to step 113. Otherwise, the determination is no, and in step 121, other processing for responding to selection of other items is executed, and then the processing returns to step 113.

  In the reset process, as shown in FIG. 8, 0 is substituted into the variable ONF in step 201. The variable ONF is for determining whether or not the user has assigned a function. The assigned value 0 indicates that it has not been done, and the assigned value 1 indicates that it has been done and is currently valid.

  In step 122 of FIG. 5 in which the determination in step 112 is NO and the process proceeds, it is determined whether or not the value of the variable ONF is zero. If the assignment of the function performed by the user to the switches 205 and 210 is valid, 1 is substituted for it, so the determination is no and the process proceeds to step 162 in FIG. Otherwise, the determination is yes and the process proceeds to step 123 where it is determined whether or not the EZ switch 210 is turned on. If the user operates the switch 210, the determination is yes and the process proceeds to step 124. If not, the determination is no and the process proceeds to step 140 in FIG.

  In step 124, a request for connection to the Internet is transmitted by the RF unit 101 to the mobile phone network. In the following step 125, it waits to receive a response on the mobile phone network side according to the request. In step 126 which shifts by receiving the response, it is determined whether or not the content of the response indicates that the connection with the Internet is rejected. If the user has not made a data communication service contract with the communication carrier, a response indicating that is received, so the determination is YES, and in step 127, the function is assigned to the switches 205 and 210. The key assignment process is executed, and 1 is assigned to each of the variables ONF and FF (S128, 129), and the process returns to step 102 in FIG. Otherwise, the determination is no and the process moves to step 130.

  As described above, in the present embodiment, when the content of the response on the mobile phone network side indicates that the connection with the Internet is rejected, the function is assigned to the switches 205 and 210. I have to. This is because the switches 205 and 210 can be used more easily at an earlier stage. The response is received by the RF unit 101 via the antenna AT1, demodulated there, and sent to the CPU.

  In step 130, it is determined whether or not the value of the variable FF is 1. If the user operates the EZ switch 210 after resetting the data communication service contract and function assignment, the determination in step 126 is NO, and the process proceeds to step 130 with 1 being assigned to the variable FF. To do. Therefore, in such a case, the determination is yes and the process proceeds to step 131, and otherwise, the determination is no and the process proceeds to step 134.

  In step 131, a pop-up screen for notifying that the functions assigned to the switches 205 and 210 have returned to the initial state is displayed on the main display unit 105. In the next step 132, it is determined whether or not the “OK” icon (button) arranged on the screen is turned on. If the user performs a click operation on the icon, the determination is yes and the process moves to step 133. Otherwise, the determination is no and the process moves to step 132a, and it is determined whether or not the “NO” icon (button) arranged on the screen is turned on. If the user performs a click operation on the icon, the determination is YES, the screen is cleared from the main display unit 105 in step 132b (erase), and the process returns to step 102 in FIG. Otherwise, the determination is no and the process returns to step 132 above. As a result, the user waits for the user to click on an “OK” or “NO” icon.

  When the process returns from step 132b to step 102 in FIG. 3, 1 is still assigned to the variable FF, so that a pop-up screen is displayed when the data communication service is used again. It will be. The initial value assigned to the variable FF is 0.

  In step 133, 0 is substituted into the variable FF. In subsequent step 134, the data of the designated URL is displayed on the main display unit 105. In the next step 135, it is determined whether or not the designated URL has been changed. If the user inputs the URL by operating the operation unit 110 or performs a click operation on the link button displayed on the main display unit 105, the determination is YES, and the changed URL is displayed in step 138. The transmission is performed from the RF unit 101, and in step 139, the response data is received, and the process returns to step 134 to display the URL data. Otherwise, the determination is no and the process moves to step 136.

  In step 136, it is determined whether or not the user has made a disconnect request, that is, a data communication service termination request. For example, when the on-hook switch 212 is operated, the determination is YES, and after the data communication by the RF unit 101 is terminated in step 137, the process returns to step 102 in FIG. Otherwise, the determination is no and the process returns to step 135 above. Thus, the state in which the data communication service can be provided is maintained until the user issues a disconnection request.

  In Step 140 of FIG. 6 in which the determination in Step 123 is NO and the process proceeds, it is determined whether or not the mail switch 205 is turned on. If the user operates the switch 205, the determination is yes and the process proceeds to step 141. If not, the determination is no and the process returns to step 102 of FIG.

  In step 141, a mail list screen on which items that can be performed by the mail function are arranged is displayed on the main display unit 105. In the subsequent step 142, one item on the list is focused and selected. In the next step 143, it is determined whether or not the cursor switch 203 is turned on. If the switch 203 is operated by the user, the determination is YES, and the process of moving the focus position in accordance with the type of the switch operated by the user in the switch 203 and the position of the focused item is executed in step 144. Then, the process proceeds to step 145. Otherwise, the determination is no and the process moves to step 145.

  In step 145, it is determined whether or not the decision switch 202 is turned on. If the user operates the switch 202, the determination is yes and the process moves to step 147. Otherwise, the determination is no and the process moves to step 146 to determine whether or not the clear switch 211 is turned on. If the user operates the switch 211, the determination is yes and the process returns to step 102 in FIG. Otherwise, the determination is no and the process returns to step 143. Thus, the state in which items on the list can be selected by operating the cursor switch 203 is maintained until the user operates the clear switch 211 or the determination switch 202.

  In step 145, it is determined whether or not the focus position item is "transmission / reception". The item is for requesting reception of an e-mail from a server installed in the mobile phone network. Therefore, when the user requests reception of the e-mail, the determination is YES, and a request for connection to the Internet is transmitted by the RF unit 101 to the mobile phone network in step 149. Otherwise, the determination is no, and other processing for responding to selection of other items is executed in step 148, and then the processing returns to step 141.

  The processing contents of steps 150 to 157, 160, and 161 following step 149 are basically the same as those of steps 125 to 132, 132a, and 132b in FIG. Therefore, detailed description thereof is omitted. If the determination in step 155 is NO, the process proceeds to step 159. If the determination in step 157 is YES, the process proceeds to step 158.

In step 158, 0 is substituted into the variable FF. In the next step 159, e-mail data is transmitted / received to / from the server. Thereafter, the process returns to step 141.
In step 162 in FIG. 7 where the determination in step 122 shown in FIG. 5 is NO, that is, the function is assigned to the switches 205 and 210 by the user, it is determined whether or not the EZ switch 210 is turned on. . If the switch 210 is operated by the user, the determination is yes, and processing A for realizing the function activated by the function assigned at that time is executed in step 163, and then the processing returns to step 102 in FIG. Otherwise, the determination is no and the process moves to step 164.

  In step 164, it is determined whether or not the mail switch 205 is turned on. If the switch 205 is operated by the user, the determination is yes, and processing B for realizing the function activated by the function assigned at that time is executed in step 165, and then the processing returns to step 102 in FIG. Otherwise, the determination is no and the process returns to step 102 in FIG. 3 without executing the processing of other steps.

  As described above, in this embodiment, when the user does not make a contract for the data communication service, the operation according to the function assigned by the user is executed by operating the switches 205 and 210. . Thereby, the user can utilize the switches 205 and 210 in a desired form.

FIG. 9 is a flowchart of the key assignment process executed as step 127 or 152 described above. Finally, the allocation process will be described in detail with reference to FIG.
First, in step 301, for example, a shortcut assignment screen as shown in FIG. 10 stored in the program ROM 103 is displayed on the main display unit 105.

  As shown in FIG. 10, the allocation screen is provided with areas for each of the EZ switch 210 and the mail switch 205, and items of selectable functions are arranged respectively. The function items assigned by the switches 210 and 205 are assumed to be selected by focusing last in the corresponding area. Here, the area for the EZ switch 210 is called an EZ area, and the area for the mail switch 205 is called a mail area.

  In step 302 following step 301, one of the items is focused in both the EZ and the mail area. In the next step 303, one of the focus is blinked. In the next step 304, it is determined whether the up / down / left / right switches constituting the cursor switch 203 are turned on. If the switch 203 itself is not operated by the user, it is determined to that effect and the process proceeds to step 307. If the user operates any of the up / down switches, it is determined to that effect and the process proceeds to step 305, where the blinking focus position is the same according to the type of switch operated by the user and the position thereof. Move between items in the area. Step 307 then proceeds. If any of the left and right switches is operated by the user, it is determined so and the process proceeds to step 306, where the blinking focus position is determined according to the type of switch operated by the user and the position. Move between. Thereafter, the process proceeds to step 307 in the same manner.

  When the blinking focus is moved between areas, the item at the position where the blinking focus was displayed in the area before the movement is focused without blinking. As a result, the user can know the item selected in the area before the movement.

  In step 307, it is determined whether or not the decision switch 202 is turned on. If the user operates the switch 202, the determination is yes and the process proceeds to step 308. Otherwise, the determination is no and the process returns to step 304 above. Thereby, the state which can select an item in each area is maintained.

  In step 308, the function of the item focused in the EZ area is assigned to be realized by the process A executed in step 163 in FIG. In the subsequent step 309, similarly, the function of the item focused in the mail area is assigned to be realized by the process B executed in step 165 of FIG. Thereafter, the series of processing is terminated.

  In this way, in the present embodiment, when the user does not make a contract for the data communication service, the function realized by the processes A and B executed by operating the switches 205 and 210 according to the user selection result. Assigned. As a result, the functions assigned to the switches 205 and 210 are changed. Such an assignment change can be performed by changing a subroutine process (subprogram) to be called by an operation on each of the switches 205 and 210, for example.

  In the present embodiment, the switches 205 and 210 allow the user to select the function to be assigned, but only one of them may be selected. The function assignment is performed immediately after a response indicating that the service is not provided from the mobile phone network side, but the user may be able to perform the function at a desired timing.

  A program for realizing the communication terminal 1 as described above may be distributed by being recorded on a recording medium such as a CD-ROM, a DVD, or a removable flash memory. Part or all of the program may be distributed via a communication network such as a cellular phone network or a public network. In such a case, the user can apply the present invention to the communication terminal device by acquiring the program and loading it into the communication terminal device. Therefore, the recording medium may be accessible by a device that distributes the program.
