Abstract

PURPOSE: A billing system and method of a mobile communication network, particularly for charging an origination terminal for a corresponding call when a received terminal of the short message makes the call as a call back, are provided to allow a receiver not to be charged for an erroneously-made call and enhance a callback call rate and efficiency of SMS advertisement. CONSTITUTION: A callback information of charge data is checked to determine whether a currently generated call is a callback call or a general call(S201,S202). If the currently generated call is the general call, a charging center extracts a phone number of an origination terminal from the charge data, calculates a corresponding telephone charge based on a call time of the charge data, and charges the origination terminal for the telephone charge(S206). When The generated call is the callback call, an HLR(Home Location Register) checks whether a destination terminal has been subscribed for a supplementary service by searching a supplementary service field for a callback call collect call service, and responds to the charging center(S203). If the destination terminal has been subscribed for the callback call collect call service, the charging center calculates a telephone charge and charges the destination call for the telephone charge(S205).

Description

Billing system and method of mobile communication network {BILLING SYSTEM OF MOBILE COMMUNICATION NETWORK AND METHOD THEREOF}

The present invention relates to billing of a mobile communication network, and more particularly, when a receiving terminal of a short message in a mobile communication network makes a call to a callback of a short message, The present invention relates to a charging system and a method for charging a mobile communication network.

The general charging method of the mobile communication network charges the call charges to the originating terminal that generated the call. As an exception, a toll service is provided as a method of charging the call charges to the receiving terminal. To use the toll-free service, you must first apply for the service and receive a toll-free phone number.

Such toll-free services are mainly used as business telephones, counseling phones, etc. of companies, but there is a problem that the burden of having to promote the toll-free telephone numbers separately and the call charges for the wrongly received telephones must be paid together.

Meanwhile, recently, advertisements using a short massage service (SMS) have been activated. Such SMS advertisements have more specific advertisements or consultations when a recipient of a short message calls a callback.

However, when the recipient of the short message calls to the callback for an advertisement or a consultation, the call rate for the SMS advertisement is very low because the user has to pay the call charge, and thus the efficiency of the SMS advertisement is low. .

On the other hand, SMS advertisements have a reverse function of spamming SMS advertisements, whereas SMS advertisements have a regular function to target advertisements at low cost. Such efforts to block spam SMS have emerged as a task for the information and communication society, along with efforts to block spam e-mail.

In addition, the spam e-mail can reveal the rejection of the message immediately by using the reject button, but the spam SMS, if you want to reveal the rejection of the message, you have to pay the call charge and call back to the callback every time Except how to erase the situation is not able to cope.

The present invention has been proposed to solve such a conventional problem, the purpose of which is to receive a short message in the mobile communication network (Short Massage) when the call to the callback of the short message to the communication fee for the call short message The present invention provides a charging system and a method for charging a mobile communication network for charging a calling terminal.

The present invention, when used as a business phone, counseling phone, etc. in the enterprise, can send a short message to the terminal that you want to talk to perform the work through a reply call, there is no need to promote toll-free phone number separately, You don't have to pay for the wrong number of calls.

In addition, when used for SMS advertising, SMS recipients will be able to call the callback without paying the call charges, which will improve the callback rate. Will improve efficiency.

In addition, since the recipient of the spam SMS calls the callback, the recipient of the spam SMS does not bear the call charges and thus can actively take action to express the rejection of the SMS through the reply call.

Is transmitted to the mobile switching center 105, and the information transmitted from the mobile switching center 105 is transmitted to the mobile communication terminals 101 and 102 via the base station controller 104 and the base station 103. In addition, the mobile communication terminals 101 and 102 provide a display function and a callback call function for the received SMS message.

A base station transceiver (BTS) connects the mobile communication terminals 101 and 102 to the base station controller 104, a digital channel unit (DCU) and a time / frequency controller (TCU). : Timing / Frequency Control Unit, Radio Frequency Unit (RFU), and Global Positioning System (GPS). The base station 103 wirelessly communicates with the mobile communication terminals 101 and 102 and performs a wired / wireless conversion function of performing communication with the base station controller 104 by wire.

The base station controller 104 (Base Station Controller; BSC) connects the base station 103 to the mobile switching center 105 to coordinate the connection between the plurality of base stations 103, supports the plurality of base stations 103, It serves as a signal processing function for communication between the base station 103 and the mobile switching center 105.

The Mobile Switching Center (MSC) connects a call when a mobile subscriber makes or receives a call. The mobile switching center (MSC) connects to the base station controller 104 to establish a call setup of the mobile communication terminals 101 and 102. It performs a release function, performs various functions related to call processing and supplementary services, and performs interworking with other networks. The mobile switching center 105 generates charging data according to call processing and transmits the charging data to the charging center 108. The charging data includes a calling terminal telephone number, a receiving terminal telephone number, a call time, callback information, and the like.

The home location register (HLR) is a database that stores permanent information of the mobile communication terminals 101 and 102 and subscribers, location information, additional service information, and the like, and is a callback call according to the present invention. It includes a supplementary service field for toll service, and interacts with the mobile switching center 105 to perform various functions related to call processing and supplementary service and to control the service.

The Short Message Service Center (SMSC) generates a short message including a calling terminal information in response to a request for transmitting a short message from the mobile communication terminals 101 and 102 to enable a callback call. It transmits to the communication terminals 101 and 102.

Billing Center (BC) receives billing data from mobile switching center 105 and performs billing processing. For the general call, the billing service is billed to the calling terminal. If the subscriber is subscribed to the callback call toll service, the corresponding charge is charged to the receiving terminal.

Usually there can be multiple home location registers 106 in one service network, and one or more mobile switching centers 105 can be connected to one home location register 106, and one mobile switching center ( The base station controller 104 may be connected to the base station controller 104, and the base station controller 103 may be connected to the base station controller 104.

Hereinafter, the mobile communication terminal 101 subscribes to the callback call toll service in order to help understand the charging method according to the present invention performed by the mobile communication system configured as described above with reference to FIGS. 1 and 2. Will be described as an example.

First, when a short message transmission request is generated from the mobile communication terminal 101, it is transmitted to the mobile switching center 105 via the base station 103 and the base station controller 104 in the same manner as a normal short message transmission path.

The mobile switching center 105 extracts the caller terminal information and the receiver terminal information from the short message transmission request signal, and requests the home location register 106 for subscriber information for the mobile communication terminal 101.

The home location register 106 replies to the mobile switching center 105 after checking that the supplementary service field for the callback call toll-free service confirms that the mobile communication terminal 101 is subscribed to the supplementary service.

Then, the mobile switching center 105 collects the caller terminal information, the short message and the callback service information, and transmits them to the short message service center 107 which manages the receiver's mobile communication terminal 102.

The short message service center 107 generates a short message including the receiver terminal information, generates a short message including the calling terminal information to enable a callback call, and sends a message requested from the mobile terminal 101. Requests the home location register 106 to confirm the location of the mobile communication terminal 102 for message transmission to the communication terminal 102.

The home location register 106 searches the subscriber information database to read the current location information of the subscriber and transmits the subscriber location information in response to the subscriber location request message from the home location register 106.

The short message service center 107 includes the calling terminal information to the mobile switching center 105 that manages the service area based on the subscriber location information transmitted from the home location register 106, so that a short message is available. The mobile switching center 105 transmits a short message capable of a callback call to the mobile communication terminal 102.

On the other hand, when the user of the mobile communication terminal 102 confirms the received short message and then requests a callback call in the state where the short message is displayed, the base station 103 and the base station controller 104 are connected in the same manner as a normal call origination path. Is passed to the mobile switching center 105.

The mobile switching center 105 extracts the caller terminal information and the receiver terminal information from the callback call, and requests the home location register 106 for subscriber information and location confirmation for the mobile communication terminal 101.

The home location register 106 checks the additional service field for the callback call toll service in the subscriber information database, checks whether the mobile communication terminal 101 is subscribed to the additional service, and reads the current location information of the subscriber. Respond to the mobile switching center 105.

The mobile switching center 105 requests a callback call to the mobile switching center 105 that manages the service area based on the subscriber location information received from the home location register 106, and the mobile switching center 105 moves. When the paging signal is transmitted to the communication terminal 101 and the call request signal is received from the mobile communication terminal 101, the communication path between the mobile communication terminal 101 and the mobile communication terminal 102 is connected.

Here, the mobile switching center 105 generates charging data including the calling terminal telephone number, the receiving terminal telephone number, call time, callback information, etc. according to the call processing, and transmits the charging data to the charging center 108, and the charging center 108 ) Performs billing processing based on the received billing data.

The charging process performed by the charging center 108 will be described with reference to FIG. 2. First, the callback information of the charging data is checked to determine whether the call currently generated is a callback call or a general call (S201 to S202).

If the current call is confirmed as a general call, the charging center 108 extracts the telephone number of the calling terminal from the charging data, calculates the corresponding call charge based on the call time of the charging data, and processes the call charge calculated at the caller, that is, the calling terminal. (S206).

On the contrary, if the originating call is identified as a callback call, the charging center 108 extracts the telephone number of the receiving terminal from the charging data and then requests the home location register 106 for subscriber information on the mobile communication terminal 101, and the home location. The registrar 106 replies to the charging center 108 after checking whether the mobile communication terminal 101 is subscribed to the additional service by searching the additional service field for the callback call toll service (S203).

Here, when the receiving terminal of the callback call is subscribed to the callback call paying service, the charging center 108 calculates the corresponding call charge based on the call time of the charging data and charges the call charge calculated at the receiver, that is, the receiving terminal (S205). .

At this time, if it is confirmed that the receiving terminal of the callback call is not subscribed to the callback call paying service, the telephone number of the calling terminal is extracted from the charging data as in the charging processing of the general call, and the corresponding call charge is calculated based on the call time of the charging data. The caller, that is, charges the call charge calculated at the calling terminal (S206).

In the above description, but limited to one embodiment of the present invention, it is obvious that the technology of the present invention can be easily modified by those skilled in the art.

For example, in the above-described embodiment, the mobile terminal is charged for the callback call only when the mobile terminal is subscribed to the callback call toll service as an example. However, all callback calls regardless of the service subscription are described. The call fee may be charged to the receiving terminal, and the mobile terminal may select whether to allow the callback call when the mobile terminal transmits the short message, or select whether to charge the call charge for the callback call to the toll free. In such a case, the calling terminal transmits the billing information together with the short message indicating whether to allow the callback call or the toll charge for the callback call when the request of the short message is requested, and the mobile switching center makes the callback based on the billing information. You will generate billing data for the call.

In addition, the charging system and method of the present invention may be linked to other communication networks, such as a wired network.

Such modified embodiments should be included in the technical spirit described in the claims of the present invention.

As described above, the present invention imposes a charge processing on a callback call of a short message to a receiving terminal. Since it can be performed, there is no need to promote a toll-free phone number separately as in the prior art, and do not have to pay a call charge for a wrongly received call.

In addition, when used for SMS advertising, SMS recipients will be able to call the callback without paying the call charges, so the call rate will be improved, and more specific advertisements or consultations will be made through these incoming calls. Will improve efficiency.

In addition, since the recipient of the spam SMS calls the callback, he / she does not bear the call charges, and thus, the recipient of the spam SMS can take an active countermeasure to express the rejection of the SMS through the reply call.

In addition to the commercial use as described above, the subscriber who has less burden on the communication fee between friends or lovers has an effect such that the calling fee is charged to the user after sending a short message to the other party.
