1 is a diagram showing the configuration of a system for charging a call distance according to the present invention, and FIG. 2 is an exemplary diagram showing a structure of detailed billing data. The mobile communication system includes a base station transceiver (BTS), a base station controller (BSC), an exchange (MSC), a home subscriber register (HLR), and a visited subscriber register (VLR) to provide call service between subscriber stations. The apparatus further includes a billing data collection / preprocessing device and a billing data processing device to process billing according to the provision. Briefly, a process of setting a call path in a mobile communication system is as follows. When the calling terminal requests a call, the subscriber station 140 requests subscriber authentication through the base station transceiver 100, the base station controller 110, and the switching unit 120, and requests the subscriber terminal 140 through the home subscriber register 130. Request location information. The home subscriber register 130 checks the destination terminal location information through the visited subscriber register 145 on the destination terminal side, and switches the switch 125, the base station controller 115, and the base station transceiver 105 corresponding to the destination terminal location. The call is set up.

The originating base station controller 110 generates detailed charging data including the calling terminal location information, the called terminal location information, and the talk time. The location information of the calling terminal may include the geographical location information of the calling terminal (for example, the latitude-longitude measured by the calling terminal using a GPS signal or the strength or time difference of the radio wave received by the mobile communication system through a plurality of base station transceivers or repeaters). Latitude-longitude, etc. measured using the terminal) or information for identifying a base station transceiver or originating base station controller (hereinafter collectively referred to as originating base station) to which the calling terminal is connected, and the called terminal location information is the geographical location information of the called terminal. Alternatively, the base station transceiver or the called base station controller (hereinafter, collectively referred to as a called base station) connected to the called terminal may identify information. Referring to FIG. 2, the detailed billing data includes caller identification information 205, originating base station identification information 210, call time 215, called base station identification information 220, and called party identification information 225. The base station transceiver or the switching center may generate the same or similar data as the detailed billing data, and the calculated billing data may be used for the billing calculation. It will be limited to the case.

The detailed billing data generated at the originating base station is collected by the billing data collection / preprocessing device 150 at a predetermined cycle or occurrence. The billing data collection device and the billing data preprocessing device may be separately configured as separate devices. The collected detailed billing data is preprocessed by the billing data collection / preprocessing device 150 for each call distance and then transferred to the billing data processing device 160.

The billing data collection / preprocessing device 150 for determining a call distance by determining the calling base station and the called base station for each detailed billing data, and inserting a predetermined call distance rate for each of the calculated call distances into the detailed billing data, the call distance rate table, A detailed billing data collector and a call distance processor. The call distance rate table includes a predetermined call distance rate corresponding to each combination of the originating base station identification information and the destination base station identification information. The detailed charging data collection unit collects the detailed charging data from the plurality of base stations. In general, detailed billing data is collected through a communication network, but may be collected in a state of being recorded in a portable storage device when a failure occurs in the communication network or incomplete data transmission due to a transmission error. Therefore, the detailed billing data collector may further include a physical interface capable of reading the detailed billing data from the portable storage device. The call distance processing unit reads the call distance rate corresponding to the combination of the originating base station identification information and the called base station identification information extracted from the detailed charging data, and inserts it into the detailed charging data. The detailed charging data in which the call distance rate is inserted is processed by the charging data processing apparatus. The billing data preprocessing function in the billing data collection / preprocessing device 150 described above may be included in the billing data processing device 160 which will be described later.

The billing data processing device 160 differentially processes the preprocessed detailed billing data for each call distance to calculate a communication fee finally charged to the subscriber. More specifically, the call distance rate is extracted from the detailed billing data received from the billing data collection / preprocessing device 150 and the call distance rate is calculated by applying the extracted call distance rate to the detailed billing data. And calculates a communication fee to be charged by summing up the charge per call for each subscriber. Operations of the billing data collection / preprocessing device 150 and the billing data processing device 160 will be described in detail with reference to FIG. 3.

3 is a flowchart illustrating a method for charging call distances according to an embodiment of the present invention, FIG. 4 is a view illustrating a call distance rate table according to an embodiment of the present invention, and FIG. 5 is an embodiment of the present invention. It is an exemplary diagram showing the structure of detailed charging data according to an embodiment.

In operation 300, the charging data collection / preprocessing device 150 collects detailed charging data from the plurality of base stations. The collected detailed billing data is temporarily stored in the storage for preprocessing.

In operation 305, the charging data collection / preprocessing device 150 extracts the originating base station identification information and the destination base station identification information from the detailed charging data. The base station identification information is unique identification information pre-allocated for each base station and is used to determine the call location of the calling terminal and the called terminal. Here, the base station identification information is basically base station transceiver (BTS) identification information, but may also be a repeater, base station controller (BSC) or exchange (MSC) identification information. That is, determining the call location of the calling terminal and the called terminal by the repeater or the base station transceiver may determine the location in more detail than determining the call location by the base station controller or the exchange. The repeater is preferably based on the location of units (eg slave devices, etc.) installed remotely.

The billing data collection / preprocessing device 150 calculates a call distance rate corresponding to the call distance by using the extracted source base station identification information and the destination base station identification information. Referring to the call distance rate table shown in FIG. 4, the horizontal axis represents the originating base station identification information, and the vertical axis represents the destination base station identification information. The extracted source base station identification information is selected from the horizontal axis index, the destination base station identification information is selected from the vertical axis index, and the call distance rate located at the intersection point is extracted. Here, the call distance rate is expressed as a weight applied to the charge per call, but the amount per reference call time is also possible. In the case of the weight, it is more preferable because it is easy to calculate the charge per call considering the call distance by multiplying the charge per call calculated by the subscriber's predetermined rate plan only by the weight. However, in an embodiment in which the subscriber excludes or selectively applies a predetermined plan, the amount of time per call may be applied. In another embodiment, the call distance rate card may be comprised of call distance versus call distance rates. The call distance rate can optionally be inserted into the detailed billing data. That is, in the embodiment of applying the call distance rate according to the distance based on the originating base station, the call distance rate exists regardless of where the called party terminal is located. In this embodiment, the call distance rate is inserted in all the detailed billing data. In embodiments where the discount rate is only within a certain distance and / or the premium rate only over a certain distance depending on the call distance, the detailed billing data belonging to the call distance section where the discount and / or the premium is not applied does not include the call distance rate. Alternatively, an indicator may be inserted to indicate that the subscriber applies data that applies a predetermined plan.

In operation 310, the charging data collection / preprocessing apparatus 150 inserts the calculated call distance rate into the detailed charging data. The call distance rate may be inserted by creating a separate field in the detailed billing data or after deleting data in the existing field. Referring to FIG. 5, detailed billing data includes caller identification information 505, calling base station identification information 510, call time 515, called base station identification information 520, called party identification information 525, and call distance rate ( 525). The detailed charging data in which the call distance rate is inserted is transmitted to the charging data processing device 160.

In step 315, the billing per call is calculated by the billing data processing device 160 for the detailed billing data into which the call distance rate is inserted. Preferably, allowing the subscriber to select a variable rate plan according to the distance of call or to select an hourly rate plan to calculate the charge per call using only one of the two plans reduces the load on the billing data processing device 160. Can be. However, depending on the distance of the call, the differential rate plan can be operated as a supplementary plan to the call hourly rate plan already selected by the subscriber, so that (1) only the rate based on the call distance or (2) the call according to the call hourly rate plan selected by the subscriber The charges based on the party charge and the call distance can be calculated together. The charge based on the distance of call is calculated as the amount of time of call based on the call time X when the call distance rate is the amount of reference time divided by call distance. If the call distance rate is the weight applied to the charge per call, first calculate the charge per call according to the call hourly rate plan selected by the subscriber, and then calculate the charge per call considering the call distance by multiplying the calculated cost per call. If rate premiums or discounts apply only to some distance segments, the detailed billing data in the premium / discount distance segments is processed according to the type of call distance rate, and the detailed charge data in the remaining distance segments is the subscriber's selected hourly rate plan. Calculate the billing per call.

Referring to FIG. 4, a call distance rate table showing weights according to call distances is shown using calling base station identification information and called base station identification information as calling terminal location information and called terminal location information. The source base station identification information and the destination base station identification information are information for specifying any one of a plurality of base stations belonging to the mobile communication system. In FIG. 4, three-digit numbers are used, but the present invention is not limited thereto. In addition, although the call distance rate is displayed as a weight in FIG. 4, the amount of time per reference call is also possible. Preferably, the distance between the originating base stations is calculated in advance to group the base stations to be charged based on the call distance. The call distance is the distance between one base station and the other base stations, and a relationship of 1: n-1 (n is the total number of base stations in a mobile communication system) is established. Distances from other base stations calculated by each base station can be integrated into one table, and have the same form as the call distance rate table of FIG. 4.

In the call distance rate table of FIG. 4, distances between base stations are divided into three groups and weighted corresponding to each group. That is, assuming that a call made within a radius of 10 KM is discounted by a certain rate, 10KM to 30KM is charged a normal rate, and 30% or more is assumed to be a certain percentage premium, the distance between all base stations belonging to the mobile communication system is calculated first. Thereafter, each base station is divided into a group within 10KM, a group of 10KM ~ 30KM and a group of 30KM or more. Finally, if the distance between base stations is within 10KM, 0.9 is allocated instead of the distance between base stations. 10KM ~ 30KM is assigned 1, and if it is more than 30KM, 1.1 is allocated. Of course, by comparing the actual location information (eg, latitude-longitude) of each base station, the distance between the receiving base station and the originating base station can be calculated for each billing data, but the base station is constantly positioned unlike the called / originating terminal. Since is fixed, it is possible to calculate the distance in advance and use it as a reference. In the embodiment in which the geographic location information is used as the location information of the calling terminal and the called terminal, the distance must be calculated for each detailed billing data.

In operation 320, the charge per call is calculated for each subscriber by calculating the charge per call calculated for each detailed billing data.

6 is a flowchart illustrating a method for charging call distances according to another embodiment of the present invention. The difference between the embodiment shown in FIG. 6 and the embodiment shown in FIG. 3 is different from the embodiment shown in FIG. 3. In the embodiment shown in FIG. In contrast to being processed by the billing data processing device after being inserted in the embodiment, the embodiment shown in FIG. 6 is that the billing data processing device calculates and processes the call distance rate when calculating billing per call without preprocessing. Therefore, in the embodiment shown in Fig. 6, no charging data preprocessing step or apparatus for inserting the call distance rate into the detailed charging data is required.

7 is a flowchart illustrating a process of acquiring a location of a subscriber station according to another embodiment of the present invention. The embodiment shown in FIG. 7 illustrates a case where geographic location information is used as location information of an originating / receiving terminal. The geographic location information is an actual location of the calling / called terminal and can calculate the call distance more accurately than when calculating the call distance based on the base station.

In step 700, if a call path between the calling / calling terminals is established, in step 705, the calling base station requests the geographic location information of the calling / called terminal to the calling party and the called party. Subjects for receiving and processing geographical location information requests may be largely divided into a base station-repeater (mobile communication network) and a mobile terminal according to the location information calculation method. Accordingly, when the mobile communication network calculates the geographic location information of the terminal, a data collection request for calculating the geographic location information is sent to the base station transceiver or the repeater belonging to the base station controller. When the geographical location information is obtained from the mobile terminal, the geographical location information request is transmitted to the mobile terminal. At this time, the mobile terminal should be equipped with GPS or equivalent geographical position information calculating means. Hereinafter, a method of obtaining geographic location information of a mobile terminal will be described. In addition to the location information system to be described later, various schemes have been developed or developed, and the present invention relates to obtaining and processing the geographical location information of the calling / calling terminal using the location information system, and thus is not limited to a specific location information system. Do not.

The location information system provided by the mobile communication service provider is a broad-based system that locates subscribers using a network system and GPS equipment, and provides additional services through the mobile network based location information system and the network based location information system. And a hybrid (hybrid) location information system. Mobile station-based location information systems include Global Positioning System (GPS), Assisted GPS (AGPS), Advanced Forward Link Triangulation (AFLT), and the like. Difference of Arrival, Angle of Arrival (AOA), Multipath Fingerprinting (Radio Camera), and a combination of geolocation systems include Qualcomm's gpsOne ^™, which combines AFLT and AGPS. GPS-based location information systems are already well known and will be omitted.

Auxiliary GPS (AGPS) is a location information system developed to solve the problems of the late system booting speed and excessive power consumption of the terminal, which are the problems of the existing GPS method. Information system.

The extended forward triangulation (AFLT) method is a method of calculating the location of a subscriber by using the time difference between a base station transmission signal reaching a terminal, and applying a network-based TDOA technique to a terminal-based method. The position calculation by the AFLT method (1) measures the arrival time of signals from three or more base stations, and (2) converts the time difference taken from each base station into a distance and draws a hyperbolic curve to calculate the location of the subscriber. . To this end, synchronization between each base station is essential, and the method of transmission time measurement, multipath, NLOS transmission, etc. determine the accuracy of the calculated position.

The radio camera method is a method of calculating the position of the terminal using both the direct path component and the multipath component of the terminal transmission signal. The position calculation by the radio camera method is performed by (1) the base station using the radio camera to create an RF signature and transmitting it to the positioning module, and (2) the positioning module has the RF signature and database. To determine the position. The characteristics of the radio camera method are that (1) unlike other network-based technologies, only signals received from one base station are used, and (2) multipath components that limit accuracy in TDOA or AOA are used as location information. Is the point. However, there is a disadvantage that radio camera equipment must be installed in all base stations.

The arrival angle (AOA) method is a method of calculating a terminal position by using a base station arrival incident angle of a terminal transmission signal. The position calculation by the AOA method is performed by measuring the incident angle of the terminal transmission signal at two or more base stations. To this end, an antenna array for measuring the incident angle at the base station is required. The AOA method determines (1) the accuracy of the position of the incident angle measurement method, multipath, NLOS transmission, multiple access interference, etc., and (2) the incident angle measurement error as the terminal moves away from the base station. There is an increasing disadvantage.

The TDOA method calculates a location by using a time difference between a terminal transmission signal reaching a base station, and does not require accurate time information on a time point at which the terminal transmits a signal. The location calculation by the TDOA method includes (1) measuring the arrival time of terminal signals at three or more base stations, and (2) converting the time difference taken to each base station into a distance and drawing a hyperbolic curve based on this to determine the position of the terminal. do. To this end, synchronization between base stations used for position measurement is essentially required. TDOA method, (1) determines the accuracy of the position of the transmission time measurement, multi-path, NLOS transmission, multiple access interference, etc., and (2) the incident angle measurement error increases as the terminal moves away from the base station have.

Hybrid method combines AFLT and AGPS, the terminal receives the transmission signal from three base stations to calculate the position by triangulation method, and auxiliary GPS signal from the communication network to calculate the position of the terminal.

The cell ID method is a method of calculating the location of a terminal by searching for a cell where a subscriber is currently located, and does not require installation of ancillary equipment at a base station, such as a home location register (HLR) or a visitor location register (VLR), which is a basic equipment of a communication network. By using the equipment of the method can determine the location of the terminal in units of cells. However, the cell ID method has a disadvantage in that the accuracy is significantly lower than that of the other location information system.

Receiving the geographic location information request in step 710 and 715, the calling party and the called party calculate the geographical location information of the calling terminal and / or the called terminal and transmits it to the calling base station controller.

In step 720, the base station controller receiving the geographic location information of the calling / called terminal generates detailed billing data including the talk time in step 730 when the call path is released in step 725, and details the geographic location information of the calling / called terminal. Include in billing data. Detailed charging data including geographic location information of the originating and terminating terminal is shown in FIG. 8. The geographic location information may be inserted in place of the source base station identification information and the destination base station identification information, but it is preferable that the geographic location information is additionally inserted while the existing field is maintained. If either or both of the calling / receiving terminals do not include GPS means or the mobile communication network cannot obtain the location of the terminal, only the base station identification information is included in the detailed billing data as shown in FIG. 3 or 6. Let's do it. The base station identification information is used in place of the geographical location information of the mobile terminal which failed to obtain the geographical location information. Preferably, the geographical location information corresponding to the base station identification information is stored in advance in a database and used for the call distance calculation.

The processing of the detailed billing data including the geographical location information of the originating / receiving terminal is the same as that of the billing data processing apparatus described with reference to FIG. 3 or 6, and the call distance using the geographical location information for each detailed billing data only. The difference is that Therefore, in the present embodiment, the call distance rate card is preferably configured as the call distance versus the call distance rate.

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

As described above, according to the present invention, the distance between the caller and the called party is measured based on the base station or the terminal, and the call rate is differentially charged for each distance, thereby providing the customer with an opportunity to select various plans. You can choose the plan that suits your taste.

In addition, in applying the charging method differentially according to the call distance, the existing mobile communication system does not cause overload or processing speed degradation. In addition, it is possible to apply differential rates according to the distance of call while maintaining various rate systems, which are advantages of mobile communication services.

In the above described with reference to the accompanying drawings a preferred embodiment of the present invention. However, the present invention is not intended to limit the scope of the present invention, the embodiments or drawings described above are for easily explaining the present invention.
