Description

  The present invention relates to a call charge distribution system for mobile phones.

  With the exception of special services such as toll-free calls for conventional calls, in the case of calls between general users, the calling party is a system that pays all call charges. There is a need to distribute to the recipients.

As a related technique, Japanese Laid-Open Patent Publication No. 6-296205 (Patent Document 1) discloses a split billing method for call charges.
In a split charge system for call charges in a switch, during a call between a calling party terminal and a called party terminal accommodated in different switches, a signal for requesting call charge split from one terminal and a signal indicating a split ratio When the terminal is sent to one of the exchanges in which the terminal is accommodated, when the one of the exchanges detects the respective signals, a signal for requesting division to the other exchange in which the other terminal as the counterpart is accommodated and a signal indicating a division ratio Is sent out. When the other exchange receives the signal requesting the division and the signal indicating the division ratio, it notifies the other terminal of the division ratio, and identifies the response content whether or not the other terminal agrees with the division ratio. Then, the data is sent to the one exchange. In the case of an agreed response from the other terminal, the division ratio is registered in the exchange that performs the billing process for the call, and the call is resumed. Calculate and register the call charges for the calling and called parties.

  That is, according to the prior art disclosed in Japanese Patent Application Laid-Open No. 6-296205 (Patent Document 1), a notification requesting to divide a charge is issued by a voice message from one terminal during a call, and the charge is divided when both parties agree. We have proposed a system that makes it possible, but it uses a method of changing the ratio during a call or a method of notifying the other party only by a voice message.

As another conventional technique, a portable terminal operator system is disclosed in Japanese Patent Application Laid-Open No. 2004-200722 (Patent Document 2).
In this portable terminal provider system, when a mail transmission request is accepted from a transmitting portable terminal, it is transmitted via a computer network, and when a mail is received via a computer network, it is transmitted to a receiving portable terminal.
The portable terminal provider system includes a billing setting accepting unit, a billing process information output unit, a billing process information receiving unit, a billing process information returning unit, a receiving side billing unit, and a transmitting side billing unit.
The accounting calculation means obtains a transmission fee that is an accounting for a mail transmission request from the transmitting-side mobile terminal and a receiving fee that is an accounting for transmission of the received mail to the receiving-side mobile terminal. The billing setting accepting unit accepts from the portable terminal on the transmitting side whether or not the transmitting side bears the billing for the mail related to the transmission request. The accounting processing information output means transmits accounting processing information including the mail identification information to be associated with the email related to the transmission request, the accounting burden setting, and the transmission fee to the receiving side via the computer network. The accounting process information receiving means receives accounting process information. The charging processing information return means further includes a receiving fee related to the mail associated with the mail identification information when the charging burden setting included in the received charging processing information indicates that the transmitting side bears The accounting processing information is transmitted to the transmitting side via the computer network. The receiving-side billing means is associated with the transmission fee included in the received billing processing information and the mail identification information when the billing burden setting included in the received billing processing information indicates that the receiving side bears. The total of the receiving fee for the received mail is billed to the receiving side. When receiving the charging processing information including the reception fee, the transmission-side charging means sets the total of the transmission fee and the reception fee included in the received charging processing information as the charging for the transmission side.

Japanese Patent Laid-Open No. 11-008717 (Patent Document 3) discloses a call charge accounting system, a communication terminal, and a center device.
In this technology, in a communication fee billing system in which billing management for communication fees associated with communication between terminals is performed by a center, a billing destination switching request for communication fees is issued from one terminal to the other terminal. The other terminal receives the billing destination switching request and issues a switching instruction to the center, and the center switches the billing destination of the call charge based on the switching instruction.

When the transmission is performed with the division ratio changed, the function key of the mobile phone is pressed on the screen 2-1, and the screen transitions to the screen 2-2. To return to the screen 2-1, press the clear key. Screen 2-2 is a screen for setting the payment split ratio, and the numerical value on the caller side can be changed in a pull-down format. When the cursor is moved to the value to be changed and the enter key is pressed, the screen transitions to screen 2-3. To return to screen 2-2, press the clear key. On the screen 2-3, the numerical value on the callee side is automatically calculated and output in accordance with the value on the caller side selected on the screen 2-2. When the call key is pressed here, the screen transitions to the screen 2-6, and the division ratio is transmitted to the mobile phone 10-2. If consent is obtained on the mobile phone 10-2 side, a call session is established after receiving the approval call approval / disapproval data, and after the call is established, the screen transits to a screen 2-5 of the in-call screen.

FIG. 3 shows an operation related to screen transition when calling from the mobile phone 10-1 to the mobile phone 10-2.
(1) Step S101
The user of the mobile phone 10-1 inputs the phone number of the mobile phone 10-2 on the outgoing screen 2-1 of the mobile phone 10-1. As for the telephone number, a record such as a telephone directory function may be read.
(2) Step S102
The user of the mobile phone 10-1 inputs the payment split ratio in a call with the mobile phone 10-2 on the screen 2-2 which is a setting screen for setting the payment split ratio. An initial value is set for the payment split ratio, and this initial value may be used as it is. To return to the screen 2-1, press the clear key.
(3) Step S103
When the user of the mobile phone 10-1 operates the call button of the mobile phone 10-1, the input information is notified from the mobile phone 10-1 to the mobile phone 10-2.
(4) Step S104
The consent on the mobile phone 10-2 side is requested for the division ratio proposed on the mobile phone 10-1 side.
(5) Step S105
If the cellular phone 10-2 side agrees to the split ratio proposed on the cellular phone 10-1 side (Yes in step S104), the cellular phone 10-1 starts from the cellular phone 10-2. Receive call approval / disapproval data.
(6) Step S106
The mobile phone 10-1 transitions to a screen 2-5 on the in-call screen after receiving approval approval / non-permission data from the mobile phone 10-2 and establishing a call with the mobile phone 10-2.
(7) Step S107
If the cellular phone 10-2 side does not agree with the division ratio proposed on the cellular phone 10-1 side (No in step S104), the cellular phone 10-1 starts from the cellular phone 10-2. Rejected call availability data is received.
(8) Step S108
If there is a proposal for the payment split ratio from the mobile phone 10-2 side and the proposal is agreed, the call is started. If the mobile phone 10-2 side does not agree with the payment split ratio proposal, the mobile phone 10-1 may transmit rejected call admissibility data to the mobile phone 10-2, and the processing may be terminated as it is. If there is no proposal for the payment split ratio from the mobile phone 10-2 side, the call is not established and the processing ends. At this time, if the key operation for ending the call is not performed on the mobile phone 10-2 side, it is possible to reset the division ratio on the mobile phone 10-1 and notify the mobile phone 10-2 side again. . When the process is terminated, the process is terminated by a key operation for ending the call. Alternatively, if there is no payment split ratio proposal from the mobile phone 10-2 side for a predetermined time, the processing is automatically terminated.
In addition, when the payment split ratio is proposed from the mobile phone 10-2 side, or when the key operation for ending the call is performed on the mobile phone 10-2 side, these are regarded as transmission of rejected call admissibility data, and actually It is not necessary to transmit rejected call availability data from the mobile phone 10-2 to the mobile phone 10-1.
(9) Step S109
As another method, when the payment split ratio from the mobile phone 10-2 side is not agreed in step S108, the user of the mobile phone 10-1 resets the payment split ratio and the mobile phone 10-1 May be notified to the mobile phone 10-2, and the consent on the mobile phone 10-2 side may be requested again (return to step S102). When the cellular phone 10-2 side does not finally obtain the consent, the call with the cellular phone 10-2 is not established, and the process is terminated by the key operation for terminating the call.

  It should be noted that the charge for communication from the transmission of payment split ratio information to the establishment of a call (call start) is borne by the caller. Similarly, when the call is not finally established, the charges during the exchange of the division ratio information are borne by the caller. Charges are generated according to the split ratio from the time when the consent of the split ratio is obtained between the caller and the callee.

Next, screen transition when the mobile phone 10-2 receives an incoming call from the mobile phone 10-1 will be described with reference to FIG.
When an incoming call is received from the mobile phone 10-1, the screen 4-1 is displayed on the mobile phone 10-2, and it is necessary to select whether or not to start a call at the division ratio proposed by the mobile phone 10-1. . As a device for intuitively identifying the split ratio on the own side, the number of the split ratio on the called party side is colored / flashed. When the user agrees with the proposal of the mobile phone 10-1, the call key is pressed to transmit approval call permission data to the mobile phone 10-1. The screen changes to screen 4-4. When the division ratio proposed by the mobile phone 10-1 is to be changed, the function key is pressed on the screen 4-1, and the screen transitions to the screen 4-2. To return to the screen 4-1, press the clear key. A screen 4-2 is a screen for setting a payment split ratio, and a numerical value on the called party side can be changed in a pull-down format. When the cursor is moved to the value to be changed and the enter key is pressed, the screen transits to the screen 4-3. To return to screen 4-2, press the clear key. On the screen 4-3, the numerical value on the caller side is automatically calculated and output in accordance with the numerical value on the callee side selected on the screen 4-2. When the call key is pressed on the screen 4-3, the screen shifts to the screen 4-5, and transmission of the reset division ratio to the mobile phone 10-1 is started. When consent is obtained on the mobile phone 10-1 side, a call session is established after receiving approval approval / disapproval data, and after the call is established, the screen transits to a screen 4-4 on the in-call screen.

FIG. 4 shows an operation related to screen transition when the mobile phone 10-2 receives an incoming call from the mobile phone 10-1.
(1) Step S201
When the mobile phone 10-2 receives information related to the payment split ratio from the mobile phone 10-1, the mobile phone 10-2 displays the screen 4-1 of the incoming call screen displaying the split ratio.
(2) Step S202
The cellular phone 10-2 requests the user of the cellular phone 10-2 to select whether or not to start a call at the division ratio proposed by the cellular phone 10-1.
(3) Step S203
When the user of the mobile phone 10-2 agrees to the proposal of the mobile phone 10-1, the user presses the call key. In response to pressing of the call key, the mobile phone 10-2 transmits approval call approval / rejection data to the mobile phone 10-1.
(4) Step S204
After the call with the mobile phone 10-1 is established, the mobile phone 10-2 transitions to the screen 4-4 of the in-call screen.

(8) Step S208
When the user of the mobile phone 10-2 presses the call key on the screen 4-3, the screen transitions to the screen 4-5, and transmission of the reset division ratio to the mobile phone 10-1 is started.
(9) Step S209
When the consent on the mobile phone 10-1 side is obtained, a call session is established after receiving the approval call approval / disapproval data, and after the call is established, the screen transits to a screen 4-4 on the in-call screen. When the consent on the mobile phone 10-1 side is not obtained, the call is not established after the rejection call permission data is received, and the process is terminated.
As another method, when there is an incoming information on the payment split ratio from the mobile phone 10-1 again, the process returns to step S201. Finally, if the mobile phone 10-2 side does not agree with the proposal on the mobile phone 10-1 side and the mobile phone 10-1 side does not agree with the proposal on the mobile phone 10-2 side, the mobile phone 10- The call with No. 1 is not established, and the process is terminated by a key operation for ending the call.

  FIG. 6 shows a screen for receiving the reset division ratio. For example, when the screen 4-5 of FIG. 4 is displayed on the mobile phone 10-2, the screen 6-1 of FIG. 6 is displayed on the mobile phone 10-1.

Next, another embodiment of the present invention will be described.
In the above, the initial value of the division ratio is “10: 0” used in the current telephone system. Here, a method of setting an initial value for each individual is considered. The screen 7-1 in FIG. 7 shows the phone book data. In addition to the generally registered data (last name, kana notation, phone number, group, E-mail address, etc.), It is possible to register the “division ratio” (“Tel ratio (outgoing)” on the screen 7-1). As a result, when a call is made by calling the other party from the telephone directory, the ratio described in the “Tel ratio (outgoing)” of the telephone directory can be automatically set as an initial value. Similarly, if it is possible to register the “division ratio for incoming calls” (“Tel ratio (arrival)” on the screen 7-1), it can be specified by “Tel ratio (arrival)” in the phone book when receiving an incoming call. It is possible to display whether the other party is making a call at a certain ratio. A screen 8-1 in FIG. 8 shows a case where the other party is making a call with “Tel ratio (arrival)” in the telephone directory. On the other hand, screen 8-2 shows a case where a call is made at a rate other than the “Tel ratio (arrival)” in the phone book, and the character string “* New setting ratio” is displayed so that it can be distinguished at a glance. Colored / flashing.
The phone book data is stored in the memory of the mobile phone 10. However, actually, the present invention is not limited to the case where the phone book data is stored in the memory of the mobile phone 10. For example, the mobile phone 10 may read and use the phone book data stored in an accessible external device on the communication network such as the call cost calculation server 30.

Further, as still another embodiment of the present invention, there is a case in which the call charge payment split ratio is registered in advance in the call cost calculation server 30 and notified from the call cost calculation server 30 to the mobile phone on the called party side. Conceivable.
For example, when the mobile phone 10-1 on the caller side tries to start a call with the mobile phone 10-2 on the callee side, the call cost calculation server 30 uses the division ratio registered in advance as the callee. The mobile phone 10-2 on the side is automatically notified. Alternatively, in response to an instruction from the mobile phone 10-1 on the caller side, the call cost calculation server 30 notifies the mobile phone 10-2 on the callee side of the division ratio registered in advance. May be. At this time, it is assumed that the communication unit 31 has a function of notifying the caller's mobile phone 10-2 of the division ratio registered in advance. The division ratio registered in the call cost calculation server 30 is registered from the mobile phone 10-1 on the caller side.
If the callee side does not agree with the split ratio proposal from the caller side, the split ratio registered in the call cost calculation server 30 is reset from the mobile phone 10-2 on the callee side. The call cost calculation server 30 notifies the caller-side mobile phone 10-1 of the reset division ratio. At this time, the call cost calculation server 30 stores, for each caller's phone number, a data table in which the callee's phone number and the payment charge split ratio are registered. Store in the management database 20.

The present invention can also be used for communication between groups using PoC (Push-to-Talk over Cellular). If the communication is one-to-one, the same processing as in the above embodiment is performed. In the case of communication with a large number of people, the payment of the call charge is divided among all the participants of the call. For example, in the case of communication with a large number of people, the mobile phone of the caller notifies the mobile phone of each participant of the payment split ratio for each of the call participants (recipients). The division ratio of each participant to the mobile phone may be the same for all participants, or the division ratio may be set individually for each participant. Similarly to the one-to-one case, only the division ratio between the caller side and the callee side is set, and the call charge for each participant is the communication charge of the callee side by the number of call participants. It may be divided.
If the called party is unhappy with the proposed split ratio, reset the split ratio and notify the caller. The operation on the called party side is the same as in the one-to-one case. If there is a person who rejects the call without agreeing to the proposal of the division ratio among the participants (incoming party) of the call, the process is terminated as the call is not established. Alternatively, as another method, the payment split ratio is reset between the sender and the remaining participants.

As described above, the present invention proposes a call charge distribution system for mobile phones that can distribute call charges between the caller side and the callee side, and a mobile phone interface and operation method used in this system. The call charges paid by the caller and the callee are determined by the payment division ratio and call time determined in advance between the two parties.
Specifically, the division ratio data is transmitted when a call is made from the caller's mobile phone to the callee's mobile phone. The division ratio data is stored in the temporary data storage unit and is also transmitted to the receiver's mobile phone. When the caller's mobile phone side agrees to the split ratio, OK is sent to the caller's mobile phone as call availability data, and a call session is established between the caller's mobile phone and the callee's mobile phone. The call starts. The call time is stored in the temporary data storage unit. Based on the division ratio data and the call time, the call cost calculation unit calculates the call charge charged to the caller's mobile phone and the callee's mobile phone user. Is stored in the call cost management database via the call cost data management unit.

  In the present invention, since the call charge is distributed between the caller side and the callee side, the call charge share ratio (payment split ratio) can be “negotiated” between the caller and the callee. If negotiation is unsuccessful, that is, if both parties do not agree even after repeated resetting of the split ratio, and one of them thinks hesitation is not clear, either one of them (both are allowed) The processing is terminated by performing a key operation (such as pressing the end-call key) to turn off.

  Thereby, call charges can be shared between the mobile phone and the caller side. In addition, it is possible to easily set the call charge payment ratio. Further, the payment ratio can be registered in the telephone book, and the initial setting value at the time of outgoing / incoming call can be automatically taken in.
