The present invention relates to a method for transmitting and receiving using two telephone numbers in one terminal and using a different payment means for each number.

A call reception process in a general mobile communication terminal is as follows.

The terminal determines the access by finding the strongest signal sent from the neighbor base station. The subscriber dials the number. At this time, the mobile identification number (MIN) and the electronic serial number (ESN) are transmitted together. When the calling mobile communication subscriber calls the called mobile subscriber, the exchange determines which subscriber's number. The exchange causes the base station to send a paging signal to locate the subscriber. Since the terminal continues to scan the call of the base station, when its number is called from the base station, it sends the ESN and MIN to the nearest base station. The base station sends this ESN and MIN to the exchange for authentication and the exchange instructs the base station to allocate a channel. When the terminal notified that the channel is allocated generates a ring signal, the call is started.

A home location register is connected to the exchange to determine where the subscriber is currently located. Each base station is connected to the exchange and is controlled by the exchange. The radio signal of the base station is transmitted through the antenna and the base station is responsible for the interface with the terminal.

In addition, a predetermined billing server is connected to the home location register to measure the talk time by the user, and the total talk time of the user is integrated for a predetermined period to settle the usage fee for the call.

1 is a schematic configuration diagram of a system for performing communication using a conventional communication terminal. Therefore, FIG. 1 is a system applied when the communication terminal has one telephone number.

As shown in the drawing, the conventional system includes the calling party's communication terminal 1 and the called party's communication terminal 2, the calling party's exchanger 3, the home location register 4, the called party's exchanger 5, and the billing server. It consists of (7).

The charging server transmits an outgoing signal from the calling party communication terminal 1 to the called party communication terminal 2 through the switch 3 and 5 and the home location register 4, and the called party communication terminal 2. When a call is initiated in response to the call, calculates a predetermined call rate proportional to the talk time, and adds the call charge to the call rate of the calling party's communication terminal 1. do.

With the development of mobile communication technology and the increase in the number of wireless subscribers, the number of people using a plurality of mobile communication terminals is increasing. For example, many people use two terminals by distinguishing between a terminal for personal use and a terminal for work provided by a company. However, in order to distinguish and use a mobile communication terminal, it is inconvenient to purchase a separate terminal and to have both terminals at all times.

In order to solve this problem, the Patent Publication No. 2001-86552 discloses two numbers assigned to one terminal, each of which can be used for different purposes, and indicates to the terminal which number is called when the call is received. A so-called two-number service method is known in which only telephone calls can be received.

However, this technique is nothing more than being able to selectively receive an incoming call according to the telephone number of the called terminal inputted by the calling party of the call. Therefore, the transmission using the two-number service was impossible. For example, it is not possible to make a distinction between when a call is made to a personal phone number registered in the mobile communication terminal and when a call is made to a work phone number.

Therefore, an object of the present invention is to provide an outgoing call by selecting an outgoing telephone number when attempting to make an outgoing call using one communication terminal assigned with a personal phone number and a work phone number.

In order to achieve the above object, the present invention, i) when the calling exchange receives the calling signal including at least the called party's telephone number from the calling party's communication terminal assigned a personal telephone number and a work telephone number, Transmitting to a home location register; ii) checking whether a division code for setting a work telephone number assigned to the calling party communication terminal as a calling party number is included in the outgoing call in the home location register; iii) transmitting the outgoing signal to a two-number server that searches for a work telephone number assigned to the outgoing communication terminal or transmits the outgoing signal to the called-side exchange terminal according to whether the distinction code is included in the outgoing signal. Doing; It provides a two-number outgoing service method comprising a.

In addition, step iii) is characterized in that it comprises the step of transmitting the outgoing signal to the destination side exchange, if the distinction code is not included in the outgoing signal.

In addition, the step iii) is characterized in that it comprises the step of transmitting the call signal to the two number server, if the identification code is included in the call signal.

In addition, iii-1) at least transmitting the personal number of the calling party and the called party number included in the outgoing call to the two-number server; iii-2) searching for a work phone number of a calling party communication terminal having the personal phone number in the two-number server; iii-3) transmitting an outgoing call using the work telephone number as a calling party number to a called party exchange; iii-4) displaying the business telephone number included in the outgoing call in the called party communication terminal through a predetermined display means; Characterized in that it comprises a.

In addition, according to whether the distinction code is included in the outgoing call, the billing target of the call charge according to the outgoing call is determined.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic structural diagram of a system for providing a two-number calling service of the present invention.

As shown in the figure, the present invention provides a calling party communication terminal and a called party communication terminal 20, a calling party switching device 30, a home location register 40, a called party switching device 50, and a two number server 60. , Billing server (70).

The calling party communication terminal 10 is a communication terminal such as a cellular phone, a PCS phone, a PDA, and the like, which provides a wireless call service using a mobile communication network, and at least a personal phone number and a work phone number are preferably assigned. The personal phone number is a phone number uniquely assigned when a user initially purchases the communication terminal and opens a predetermined communication function, and the work phone number is a second phone number assigned to the communication terminal. The work phone number is preferably a phone number for paying for improving the work of employees in a place such as a company and paying a telephone fee used through the phone number in the name of the company.

The switch 30 and 50 are mobile switching centers (MSCs), and are devices that transmit a digital signal converted from analog voice data of a user together with other input signals to a backbone network of a mobile communication network or vice versa. .

The home location register (40) is a home location register (HLR), which always checks and stores the location of the mobile communication terminal, while the called party communication terminal 20 is located according to a call request (outgoing call) from the exchange. The call signal is transmitted to the exchange side.

The two-number server 60 is a database operated by a predetermined communication company, and stores at least the unique telephone number (mainly a personal telephone number) of the calling party communication terminal 10, and is additionally assigned to the unique telephone number. A second telephone number (mainly a work telephone number). Accordingly, in response to a request for searching for a work phone number from the home location register 40 which has received a predetermined call from the calling exchange 30, the work phone number connected to the personal phone number included in the call is retrieved. The searched phone number is transmitted to the home location register 40, or the calling signal is transmitted to the called side exchange 50 where the searched phone number is located.

The billing server 70 interoperates with the home location register 40 and the two number server, and when a predetermined call is initiated according to an outgoing signal of the calling party communication terminal 10, the duration of the call is determined. The call charge calculated in accordance with the predetermined rate system corresponding to the time is measured and charged to the calling party communication terminal 10. Further, the charge of the billing server 70 according to the present invention is preferably imposed separately on the personal phone number and the work phone number.

3 is a flowchart illustrating a signal for attempting to make a call using a work phone number in the two-number calling service providing method having the above configuration.

The originating switch 30, which has received an outgoing call from the calling party communication terminal 10 assigned with at least a personal phone number and a work phone number, transmits the outgoing signal to the home location register 40 (S11). The outgoing signal preferably includes at least a telephone number of the calling party communication terminal 10 and a telephone number of the called party communication terminal 20. In addition, the outgoing call includes a predetermined division code for setting a work telephone number assigned to the calling party communication terminal 10 as the calling party number. The identification code is a combination of numbers such as, for example, "# 22", and an outgoing signal having the identification code is input from the user through the calling party communication terminal 10 in the form of "# 22 011 234 5678". If so, the calling party communication terminal 10 transmits an outgoing call including a predetermined calling party number to the switch.

In addition, the predetermined calling party number included in the outgoing call is preferably a personal telephone number. The reason is that a user usually purchases his own communication terminal and uses his assigned unique phone number as his personal phone number, and the company where the user works often provides a new work phone number. In addition, after the communication terminal is provided by the company, the user may give a personal telephone number to the communication terminal, and in this case, it is preferable that the personal telephone number and the work telephone number in the following description are replaced with each other. Do.

Next, the home location register 40 receiving the originating signal from the originating exchange 30 checks whether the division code is included in the originating signal (S12). 3 is a diagram illustrating a case in which a division code is included in the call signal, and a case in which the division code is not included in the call signal will be described later with reference to FIG. 4.

The home location register 40 confirms that a predetermined division code is included in the outgoing signal, and extracts a phone number of the called party's communication terminal 20 from the outgoing signal, and the area where the called party's communication terminal 20 is located. Determining the position of the called-side communication terminal 20, including the process of determining the position of the called-side exchange 50 of (S13).

The home location register 40, which has grasped the location of the called side exchange 50, includes the location information or routing information of the called side exchange 50 in the outgoing call and transmits it to the two number server 60 (S13). ). When receiving the outgoing call, the two-number server 60 extracts the calling party number from the outgoing call and searches for a predetermined work telephone number connected to the calling party number (S14). In the received outgoing call, a personal outgoing call number is first replaced with the searched work phone number, and a new outgoing call is created to make a new outgoing call according to the routing information of the called exchange 50. Send it.

The called party exchange 50 transmits a call request signal to the called party's communication terminal 20 of the called party's telephone number included in the outgoing call when receiving the outgoing signal including the work phone number as the calling party's phone number. (S15). Then, the called party communication terminal 20 receiving the call request displays the work phone number as a calling party number on a predetermined display unit (not shown) and simultaneously generates a visible and audible signal for receiving a call request signal. Notify the arrival of the call request.

Thereafter, when the user accepts the call request by pressing the "call" key of the called party communication terminal in response to the call request, a call between the calling party communication terminal 10 and the called party communication terminal 20 is received. Is started (S16).

In addition, the process of S14 may include the step of transmitting the search results back to the home location register 40 by searching for the business phone number in the two-number server (60). In this case, the home location register 40 may perform the procedure for determining the location of the called party communication terminal 20 and the called party exchange 50 before and after the steps S12 to S14, so that the home location register 40 may be more fluid. It becomes possible. In this case, the home position register 40 is responsible for the transmission of outgoing signals to the destination side exchange 50.

4 is a flowchart of a signal in a call using a unique telephone number in the two-number call service providing method.

The originating exchange 30 which has received a predetermined outgoing signal including the telephone number of the called party's communication terminal 20 from the calling party's communication terminal 10 transmits the outgoing signal to the home location register 40. (S21).

The home position register 40 having received the call signal performs a procedure of checking whether a predetermined division code is included in the call signal (S22). As a result of the check, if it is determined that the distinction code is not included in the outgoing signal, the home location register 40 transmits the outgoing signal to a predetermined destination side in charge of the area where the destination side communication terminal 20 is located. The call signal is transmitted to the exchange 50 (S23).

Of course, before performing the procedure of the transmission of S23, the home location register 40 performs a procedure to determine the location of the called party communication terminal 20 or the location of the called party exchange 50. The location determination process may be performed before or after determining whether the division number is present.

The receiving side exchange 50 receiving the outgoing signal transmits a call request according to the outgoing signal to the called side communication terminal 20 (S24). The called party communication terminal 20 displays the personal telephone number of the calling party communication terminal 10 included in the outgoing call as a calling party number on a predetermined display unit and generates a predetermined call request notification signal. When the user inputs a predetermined call start signal through the called party communication terminal 20 in response to the notification, the calling party communication terminal 10 and the called party communication terminal 20 are connected to each other to perform communication. It is made (S25).

Although the process of FIG. 4 illustrates a process of attempting to make a call using a personal phone number without using a predetermined classification code in the present invention, except for determining the presence or absence of the classification code, a conventional unique number It can be seen that it is similar to the process of attempting to send using a communication terminal having only one.

3 and 4, the home location register and the two number server 60 are preferably connected to a predetermined billing server 70. Therefore, when the origination and call is initiated using the work phone number as shown in FIG. 3, it is preferable to charge the call charge to the work phone number, and when the call is made with the personal phone number as shown in FIG. It is a good idea to charge your call number. To impose a communication fee on the phone number means to charge a call fee to a predetermined billing subject and billing means specified when the phone number is assigned to a predetermined communication terminal. For example, if the communication terminal is owned by a user and is assigned a work telephone number from a company and is using the two-number service, the caller designates the user when the call is made using the personal telephone number as a calling number. If a charge is charged by the payment method of the user and the call is made to the work phone number including the identification code, the charge for the call is charged to the company providing the work phone number.

The present invention having the above-described configuration can be used by distinguishing the personal phone number and the work phone number when a call is made to a predetermined destination communication terminal using a communication terminal assigned with a personal phone number and a work phone number. Since it is possible to distinguish between a work call and a personal call, the personal phone number is not exposed to work, thereby protecting the personal privacy.

In addition, since the target person of the billing can be specified differently according to the business call and the personal call, there is an advantage that a communication fee for the work call may not be paid when an individual uses his or her communication terminal.

In addition, by assigning a predetermined work phone number to an individual communication terminal, the two-number service can be used, thereby reducing the purchase cost of a new communication terminal because it is not necessary to pay each individual a new communication terminal for business use. There is an effect.
