Abstract

PURPOSE: A method for imposing charge on a collect call is provided to apply the collect call to a call for an incoming signal during absence, and to lighten a load for a call-back service of a cellular phone user using a fixed sum system. Also, the method is automatically handled only by adding a simple control code. CONSTITUTION: A control code representing a telephone number of a receiving party and call-back is pressed to generate a service request signal(S1). An originating office exchange receiving the service request signal stores corresponding call-back request information in a predetermined storage unit(S2). Information on a telephone number of an originating party including call-back information is transmitted to a phone of the receiving party from the originating office exchange(S3). A call-back reply signal is generated in compliance with a call attempt responsive to the call-back of the receiving party(S4). The originating office exchange receiving the call-back reply signal compares the call-back replay signal with the call-back request information stored in the storage unit to check the validity of the call-back reply signal(S5,S6). And if the call-back reply signal is normal, a speech path is formed and a charge for a call is imposed to the first service requesting party(S7).

How to charge for toll-free phone charges {A method of charge for a collect call}

The present invention relates to a method for charging a toll free telephone bill, and more particularly, to a method for automatically charging a telephone bill for a missed incoming call or a preset relationship.

With the development of technology, cellular phones are widely used by office workers, college students, and even elementary, middle and high school students. Such an additional function of the mobile phone has a caller identification function. Of course, it is a trend that an additional function corresponding to an option or most mobile phone users are using for convenience. In addition, as a countermeasure for people with unhealthy intentions, the number of households installed by connecting a caller display device to a general landline telephone is increasing, and a telephone having a caller display function is being produced and disseminated.

In case of a missed call or in the form of a text message, the call is made to the number. At this time, the telephone charges generated are the responsibility of the caller. However, there may be various forms of using a collect call system through such a missed call indication or a call-back service by SMS.

For example, a parent with a child using a mobile phone may need these services. In most cases, mobile phones for middle and high school students use a flat fee system. Therefore, you will need a collect call so that your children do not feel burdened by the reduction in their available balance.

Another example would be a person who needs the service so that if they leave a phone number with a message to a lover or a crush, they can be called freely.

Sometimes, even if you see an unfamiliar phone number displayed on the missed call, you are wondering about the burden of the call, but you do not want to ignore the call, or the caller pays for the callback of the missed call so that the caller does not get married. You may also want to deal with this.

However, the current telephone bill system does not meet these demands.

It is an object of the present invention to provide a new method of charging a toll free telephone bill.

It is another object of the present invention to provide a method for charging a toll-free telephone fee for an answering call for an incoming call.

It is still another object of the present invention to provide a method for charging a telephone charge, which can reduce the burden on the return call charge of a mobile telephone user using a flat rate system.

Still another object of the present invention is to provide a method for charging a toll free telephone bill that can be automatically processed by simply adding and using a simple control code.

Toll charge method according to the present invention for achieving the above object comprises the first step of generating a service request signal by pressing a control code that can indicate the telephone number and call-back of the receiver; A second step of storing the callback request information in a predetermined storage device by the calling terminal exchange receiving the service request signal; A third step of transmitting caller's telephone number information including call-back information from a calling party station switch to a caller's telephone; A fourth step of generating a callback response signal in response to a call attempt by the receiver in response to the callback; A fifth step of confirming the validity of the callback response signal by comparing the callback request information stored in the storage device in the calling station switching station receiving the callback response signal; When the callback response signal is normal, the call path is formed, but the first service requester is characterized in that it comprises a sixth step of charging the call charge.

Detailed features of the toll-free charging method according to the present invention is shown as a text message including a callback request signal when the receiver's phone is a mobile phone, and the caller's telephone number and callback request when the landline phone has a caller display function. It is a point indicating a signal.

Another detailed feature of the toll-free charging method according to the present invention is that the callback response signal of the receiver includes a control code that can indicate the telephone number and callback response of the original caller.

1 is a flow chart showing the process of the toll charge method according to the present invention.

2 to 6 are configuration diagrams showing various application embodiments of the present invention according to the type of telephone.

Hereinafter, with reference to the accompanying drawings will be described a toll charge method according to the present invention.

1 is a flow chart showing the process of the toll charge method according to the present invention. First, a person who wants to use the service according to the present invention presses a control code for requesting a callback together with a counterpart's telephone number to call. For example, suppose you press * after a telephone number. This assumption is for the purpose of illustrating the present invention and does not necessarily imply a preferred control code. That is, there may be a method of pressing a specific telephone number (000) first and then pressing a counterpart's telephone number, or a method of pressing a control code and a telephone number such as a combination of ＊ or ＃.

As described above, by pressing the other party's telephone number and control code, if the call is not possible and the call is transferred to the missed call, the user intends to use the service. If the call is available, the control code is invalidated by the call, and if the call is switched to the missed caller ID, it is regarded as the occurrence of the corresponding service request. In some cases, you may want to use this service on purpose. This is the case where you want to give a call option to the other party. That is, there may be a case in which a toll service for a response call to a questionnaire through a text message or a case in which a male or female heterosexual relationship is desired is known. At this time, it would be desirable to use a control code differentiated from the above case (S1 process).

The callback request information is stored in the database device connected to the calling party exchange of the corresponding carrier or mobile carrier as shown in [Table 1] below. [Table 1] below shows an example stored in a database connected to an originating terminal switch of a 011 mobile communication operator. It includes the date and time, the telephone number of the person requesting the use of the service, and the telephone number of the beneficiary of the service.

This information is to store the telephone number of the callback service requester and the service beneficiary for accurate calculation of the call charge when the call request signal according to the callback response is received again from the service beneficiary (S2 process).

Embodiments for performing the telephone billing method according to the present invention may have various cases as shown in Figs. Figure 2 is an exemplary view showing a case in which the subscriber A mobile carrier intends to use the receiver toll payment system according to the present invention for subscribers B mobile communication. Control code to know that the other party, that is, a call-back service request together with the telephone number of the person who requested the service according to the present invention by the caller indication through the missed call number or the message function of the mobile phone subscriber of the B carrier Is displayed. For example, * may be displayed first, and the caller's telephone number may be displayed. Thus, the recipient can recognize that the telephone charges are charged in the form of toll charges when he / she answers the corresponding telephone number.

3 illustrates an example in which the other party is a subscriber using the same mobile communication company. Figure 4 is an exemplary view showing that the mobile subscriber A uses the service according to the present invention with respect to a landline telephone connected to a caller display device or a landline telephone having a caller display function. 5 is an exemplary diagram illustrating a case where a wired telephone user wants to use a service according to the present invention to a subscriber of a B mobile communication company. 6 is an exemplary view when a landline telephone user wants to use a service according to the present invention with respect to a landline telephone connected to a caller display apparatus or a landline telephone having a caller display function (S3).

The receiver attempts to answer the callback by recognizing that the caller has requested the call-back service to himself through the caller's telephone number including the control code. At this time, the callback response signal may also appear in various forms. Pressing the caller's phone number after a specific phone number 999 or pressing 뒤에 after the caller's phone number allows the caller to know that it is a response signal for a call-back (S4 process).

The callback response signal is transmitted to the calling terminal exchange of the corresponding communication company, and the corresponding communication company recognizes the callback response signal through the received signal and transmits the call request information to the calling terminal switching station of the service provider of the service requester. That is, except in the case of using the same carrier as shown in Figure 3, in Figures 2, 4, 5, 6 transfers the corresponding information from the B mobile carrier switch to the A carrier switch (step S5).

The exchange that receives the callback response signal determines whether the callback response signal is valid by checking the data stored in the database as illustrated in [Table 1]. At this time, if there is no callback service request or is received after the validity period of the callback service, it is determined to be abnormal and a callback response message (in the form of voice or text message) indicating that it is impossible to provide toll-free charge service. Provide the phone number of the signal generator. (S6 process)

If the callback response signal is normal, a call path is formed, but the cost (telephone charge) according to the call is charged to the first service requester (S7 process).

For example, a mobile phone user whose telephone number is 011-123-4567 as a subscriber of a mobile carrier named A and whose son uses the telephone number 016-987-6543 as a subscriber of a mobile carrier B is a toll free telephone according to the present invention. Assume the service was charged at 7:42 pm on July 8, 2002. In other words, he presses "*" one after another with his son's telephone number, indicating his intention to use the service. This information is stored in the database of mobile carrier A as shown in [Table 1]. If the son is in class or is a subscription mobile phone user, his son's cell phone is marked with "* 011-123-4567". The son knows that the message is sent by the father, and presses "＃" with the father's telephone number 011-123-4567 to inform the exchange of the mobile carrier of the callback response. The B-carrier notifies the A-carrier of the callback response signal, and the A-carrier checks the database to determine the validity of the callback response signal. If it is found to be valid, it connects the channel and charges for the call are charged to the father's phone number 011-123-4567 as shown in [Table 2]. Of course, you need to tell Mobile B before the start of the call that A will handle the cost for the call. This is to prevent a double charge error on the call.

As described above, using the toll-free charge method according to the present invention, a caller using an incoming call number can be freely called, and a parent can call a teenager using a flat-rate mobile phone. When you have the effect of relieving the burden of telephone bills.
