Operation Control Method of Mobile Terminal for Real Time Billing Information}

The present invention relates to a method for controlling a mobile terminal, and more particularly, to a method for controlling a mobile terminal for displaying a real-time billing information which is easy to input a country code and expresses real-time billing information for a currency when an overseas call is made.

Voice calls are mainly made by mobile terminals such as mobile phones and smart phones. A wireless network for a mobile terminal divides a service area into unit cells, and each cell has a base station to form a wireless communication channel between each cell, thereby providing voice communication and data communication to a user of the mobile terminal. On the other hand, the role of the existing wired network (PSTN) has been reduced as the portable terminal has been spreading, and is being used as a data line for a data communication network, or has become a trend. However, the existing wired network does not require any additional equipment, and since it has been installed underground or on the ground for a long time, when the distance between the sender and the receiver is not long, the cost may be lower than the voice call using the wireless network. By using these advantages, the mobile terminal can make a call connection to one of the wired network and the wireless network by using the dead wired network. Thus, voice communication using the wireless network is more expensive than voice communication using the wired network. It has been proposed to lower the cost cheaply.

When the mobile terminal requests a call connection, the caller can make a voice call through the caller and the wired or wireless network by referring to the call connection information provided through the packet network, thereby reducing the call charge when the caller uses the wired network. Can be. However, this approach can lower call charges only if the caller is using a wired network, and the caller does not have any other means to lower call charges. Therefore, there is a side that cannot be seen as a true cost reduction.

In addition, the increase in call cost is more prominent when the caller and the receiver make the voice call longer than necessary, but until now, no mobile terminal control method for notifying the user of the charges incurred during the voice call has not been proposed.

The payment method may be one of cash payment, prepaid card payment, postpaid card payment, card payment, mileage, flight mileage, virtual account, electronic coupon, electronic wallet point, and point payment, and payment of currency by mobile payment. Can also be used as a payment means.

Here, the callback call method means that when the app 51 attempts to make a call to the receiver (requested as a packet through the access module 110), the device makes a call to both sides.

There are three ways to call back.

① Calling the caller and the called party (receiver) at the same time from the equipment (call processing module 140)

② The equipment (call processing module 140) walks the caller first and then the caller (the receiver)

③ The equipment (call processing module 140) to the first caller (receiver) and then walk to the caller

There is this.

The prefix call type represents a representative number service type such as "1588", and the toll free type call number is a number beginning with "080". The call connection is connected from the calling mobile terminal to the server, but the call cost is transferred from the server side. The terminal user represents a method of not adding a call cost, and the toll-free method represents a call method having a free phone cost.

The call processing module 240 determines a communication route in which a minimum cost occurs by referring to a call method set in the caller portable terminal 100 and a payment method. The communication route may be composed of one or a combination of two or more routes, and when the sender portable terminal 100 and the receiver terminal 251 are remotely separated, for example, the sender portable terminal 100 and the receiver terminal 251. In case of making international call, it may consist of a combination of multiple communication routes rather than a single communication route. When combined in plural, the individual communication routes constituting the entire communication route may incur costs between the base station, switching center, radio station, relay station, and server, and the cost of the individual communication route divided by the unit time (for example, one second). These may be different from each other. When the caller mobile terminal 100 connects to the wireless network with the connection module 210, the caller module 240 notifies the telephone number of the receiver terminal 251, so that the call processing module 240 of the receiver terminal 251 in the caller portable terminal 100. It is possible to select a combination of individual communication routes that incurs the lowest cost among combinations of individual communication routes to the location. If the lowest cost is satisfied even with a single communication route, the call processing module 240 may select one communication route.

The call processing module 240 may provide the caller's mobile terminal 100 with the rate of the communication route determined as the lowest cost (or one or the sum of the rates of the individual communication routes) through the access module 110. The caller portable terminal 100 may calculate a sum of rates for the communication route, the communication route, or be notified using the installed app. The rate is a cost per unit time, so it increases in proportion to the talk time.

The call processing module 240 provides the receiver terminal 251 side phone number in the caller portable terminal 100 connected to the wireless network through the access module 110, and records the data in the database 260 when requesting a call connection. The sender portable terminal 100 may be authenticated with reference to the user information. In addition, the call processing module 240 may determine the payment means recorded in the database 260 and the available payment costs for each payment means. If there is no balance in the payment means selected by the caller portable terminal 100, the charging method for the payment means may be requested to the caller portable terminal 100 through the access module 110. In this case, the payment method may be one of cash payment, prepaid card payment, postpaid card payment, card payment, mileage, flight mileage, virtual account, electronic coupon, electronic wallet point, and point payment, the payment of currency costs by mobile payment Can also be used as a payment means.

The call processing module 240 may change the communication route according to the payment method. For example, when the payment method is a prepaid card or a postpaid card, the rate at a particular communication route may be discounted or provided free of charge for a certain time. Therefore, the call processing module 240 should determine whether the payment means for the communication route is lower or higher than the predetermined rate, and may change the communication route according to the determination result. The call processing module 240 may provide CDR information to the billing module 250 after the caller portable terminal 100 and the receiver terminal 251 request a call connection.

The billing module 250 may charge the caller portable terminal 100 according to a call method set in the caller portable terminal 100 after a call connection is made between the caller portable terminal 100 and the receiver terminal 251. have. When the billing module 250 performs a call connection between the caller mobile terminal 100 and the receiver terminal 251 in the call processing module 240, the billing module 250 stores the CDR information until the call connection is terminated from the call processing module 240. And receiving the final charging information and the real-time charging information based on the CDR information. In this case, the billing module 250 may be the same as or similar to the billing information calculated by the mobile terminal 100 side app. The mobile terminal 100 receives the CDR information provided from the billing module 250 through the access module 210, or real-time billing in the app by applying the call method set in the mobile terminal 100 and the rate for each communication route. You can create your own information. Therefore, the real time charging information calculated by the mobile terminal 100 and the charging information calculated by the billing module 250 may be the same.

The mobile terminal 100 may generate real-time billing information using the CDR information provided by the billing module 250 through the access module 210, but rather, multiply the rate information for each communication route by the call time and real-time billing. It is desirable to calculate the information. When the mobile terminal 100 uses the CDR information provided by the billing module 250, the billing module 250 may continuously transmit and receive CDR information with the mobile terminal 100 through the connection module 210.

The final billing information can be obtained by multiplying the talk time by the time ending from the start of the call connection. For example, assuming that there is one communication route, the rate is $ 0.1, and the talk time is 60 seconds, the final billing information may be calculated as 0.1 X 60, that is, $ 6. If the communication route is a combination of a plurality of individual communication routes, the communication time may be multiplied by the rate of each individual communication route.

The real time charging information may be calculated by the billing module 250 and provided to the sender portable terminal 100 or the receiver terminal 251, or may be calculated by the portable terminal 100 that spends money. When real-time charging information is calculated in the mobile terminal 100, the app installed in the mobile terminal 100 may refer to the rate information for each communication route provided by the billing module 250.

Here, the real time may be provided every second (1 second), or 10 seconds, 1 minute period. However, it is not limited.

On the other hand, real-time billing information billing module 250 provides the rate information to the caller mobile terminal 100 that pays the call cost through the access module 110, the app installed on the caller mobile terminal 100 and the rate The call time may be multiplied and displayed on the display unit in real time.

In addition, the billing module 250 may generate billing information using two or more plans. For example, if a free call remains in the mobile terminal 100, the mobile phone 100 will be treated as a mobile phone bill during the time when the free call is exhausted, and thereafter, charging information according to another cheap call method may be used. The billing module 250 may support the user of the mobile terminal 100 to make a voice call with a minimum call cost.

The database 260 may include billing information, region rate information, country rate information, payment rate information, and payment rate information for the previous call history of the caller portable terminal 100. In addition, CDR information transmitted between the billing module 250 and the call processing module 240 may be recorded.

The access module 111 may be connected to the call system 200 through any one or more of a CDMA network, a WCDMA network, an LTE network, an LTE advancd, a GSM network, Wifi, or Wibro, and after accessing the call system 200, By accessing the update module 220 and the installation download module 230 through the call system 200 side connection module 210, a version check of an app may be performed, and if a new app exists, a new app may be downloaded. . In the case of downloading a new app, the app may install the new app on the mobile terminal 100 and restart to perform the new app.

The billing module 113 refers to a call method set in the mobile terminal 100 and a communication route when the call connection is performed from the mobile terminal 100 to the receiver terminal (mobile terminal, smartphone, general telephone, VOIP telephone, etc.). To determine the rate per communication route, multiply the call rate by the identified rate to generate charging information in real time and display it on the display. The communication route may be a single communication route, but the entire communication route may be formed by a combination of two or more separate communication routes when the sender and the receiver are located at a remote location, such as an international call. In this case, the sum of the rates of the respective communication routes may be multiplied to generate a call cost, that is, charging information for the entire communication route. The app installed in the mobile terminal 100 may display the charging information calculated in real time on the display unit of the mobile terminal 100 or may notify a voice by a predetermined amount.

The charging module 114 displays an interface required for charging the call system 200 when the mobile terminal 100 makes domestic and international calls on a display unit and displays a user selected payment means (cash, point). , Mileage, etc.), and the value according to the payment method is requested to charge the call system 200. When the user selected payment means is card payment, the charging module 114 may purchase points and miles using the card payment and use the phone terminal in the mobile terminal 100. When the user of the portable terminal 100 completes charging, the charging module 114 may display the details of the charge of the portable terminal 100 on the display unit.

For example, the charging module 114 may provide a friend or acquaintance of the user of the mobile terminal 100 with his or her own points, miles, and cash so that the friend or acquaintance may make domestic and international calls using the same. The value (cash, mileage, point value) according to the payment method may be provided to a friend or acquaintance in the charging process, or may be moved from the information provided by the call system 200 with respect to the mobile terminal 100. At this time, the charging module 114 may request a charging for the phone number specified by the user of the mobile terminal 100 to the billing module 250 of the call system 200, and the phone number is directly input from the mobile terminal 100. Or from an address book of the mobile terminal 100.

The interface module 112 provides an interface for selecting a country code to a display unit of the portable terminal 100 when the user of the portable terminal 100 wishes to make an international call. When the user of the mobile terminal 100 wishes to make an international call, the interface module 112 displays a national flag image on the display unit of the mobile terminal 100 and receives a user's touch input or key input. When the user selects one of the country images, the interface module 112 recognizes a country in which the user wants to make a call, and may recognize a country code corresponding to the user-selected country image even if the user does not input a country code. Thereafter, the user of the mobile terminal 100 may complete the input of the number for the international call by inputting the telephone number of the receiver terminal after the country code.

The country images may be sequentially displayed on the display unit in alphabetical order, alphabetical order, or in the order of the countries where the mobile terminal user frequently makes a phone call. The interface module 112 may display the rate of the communication route according to the user selected country and the location of the receiver terminal located in the corresponding country on one side of the display unit. In this case, the phone call may be displayed by displaying the local time of the corresponding country together. To determine the time it will take. For example, if the local time in Korea is 3:00 o'clock and the local time on the receiver's terminal is 3:00 am, it is not an appropriate time zone for telephone calls.
