Apparatus and Method for Billing Data Distribution for Rater Systems of Mobile Communication Systems}

The present invention relates to a billing data distribution device and method in a mobile telecommunication fee calculation system, and more particularly, to a method for collecting billing data from a mobile communication switch and distributing the collected billing data to a plurality of bill calculation devices. It is about. The present invention can distribute the total billing data collected according to the load balance and customer information of each billing device, it is possible to perform efficient billing.

1 shows a schematic configuration of a fee calculation system in a conventional mobile communication system.

As shown in FIG. 1, when a call is requested from a terminal 105 of each subscriber, a call processing signal is received at the base stations 100a, 100b, ..., 100n, and the mobile communication is performed through the base station controller 110. To exchangers 120a, 120b, ..., 120n. The mobile communication exchangers 120a, 120b, ..., 120n received in response to the call request generate a call to provide a call service and generate a charging data record (CDR). Such billing data includes call detail information such as called party number, calling party number, call type, call start time, call end time and other information necessary for billing.

The fee calculation system 50 is comprised with the billing data distribution apparatus 130 and the fee calculation apparatus 140a, 140b, ..., 140n. Here, the billing data distribution device 130 performs a function of collecting and distributing billing data generated by each of the mobile communication switchboards 120a, 120b, ..., 120n, and the bill calculation device 140a, 140b, ... , 140n) calculates the fee for each user using the billing data.

In the related art, the fee calculation devices 140a, 140b, ..., 140n corresponding to the mobile communication switches 120a, 120b, ..., 120n are preset. The billing data distribution device 130 collects billing data generated by each of the mobile communication exchangers 120a, 120b, ..., 120n, and stores the collected billing data in the mobile communication exchangers 120a, 120b, ..., 120n. ), And the classified billing data are distributed to the respective fee calculation devices 140a, 140b, ..., 140n. This distribution procedure is performed for all billing data collected by the billing data distribution device 130.

That is, in the related art, the billing data distribution device 130 distributed billing data to each bill calculation device 140a, 140b, ..., 140n according to the mobile communication exchange that generated the call, and each bill calculation device 140a. , 140b, ..., 140n) have previously provided subscriber numbers to be processed according to the classification of the mobile communication exchange, so that only charging data generated by the mobile communication exchange could be processed. Therefore, there was an unreasonable point that the charge calculation devices 140a, 140b, ..., 140n have to transmit the billing data corresponding to the subscriber number which they cannot process to another suitable charge calculation device.

An explanation will be made for the irrational points of the conventional system as an example.

Each mobile communication switch 120a, 120b, ..., 120n has an identifier such as name or region (for example, Seoul Guro 1 Switch, Seoul Guro 2 Switch, Busan Exchange, etc.). As such, a group is formed by tying a mobile telecommunication switch in a Seoul area, and a group is formed by tying a local telecommunication switch in a local area. That is, it is assumed that the mobile communication exchange is classified based on the region.

The fee calculation devices 140a, 140b, ..., 140n are pre-assigned in correspondence with each classified mobile switching center group. As in the above example, a fee calculation device corresponding to each group of mobile communication exchanges is named as a fee calculation device and a local fee calculation device in Seoul, respectively.

Therefore, if a subscriber's terminal requests a call through the Seoul Guro 1 exchange, the call is made, the calling party number corresponding to the subscriber's terminal and the mobile communication exchange identifier of the Seoul Guro 1 exchange will be recorded in the billing data. This billing data is generated by the mobile communication exchange to which the call is connected. The charging data distribution device collects the charging data generated in this way, and reads the mobile communication exchanger identifier called "Seoul Guro 1 Switch" from the collected charging data. Therefore, the collected billing data is distributed to the fare calculation device in Seoul to perform the charge calculation.

However, when a subscriber of a province (Busan, Busan) makes a call in Seoul, the identifier of the mobile communication exchange of Seoul is recorded in the generated billing data, and the billing data is distributed to the billing device of Seoul. In this case, the fare calculation device of Seoul is provided with information for processing the subscriber number of Seoul, and determines whether the customer group information is appropriate by referring to the calling subscriber number in the distributed billing data. Since the originating subscriber number of the billing data corresponds to a local subscriber, the billing data should be transmitted from the billing device in Seoul to the billing device in the province.

As in the above example, the distribution method corresponding to the conventional mobile communication switch is unnecessary because the fee calculation device determines whether or not the billing data to be processed is suitable, and the unsuitable billing data must be transmitted to another suitable billing device. There may be a process of transmission of compliance and transmission load.

Particularly, when the number of subscribers is millions or tens of millions, the calculation of the charge in one device requires a very high-performance charge calculation device, which is very inefficient in terms of cost and performance. Therefore, it can be said that it is efficient in terms of cost and performance that the fee calculation is performed in a plurality of fee calculation devices.

In other words, two or more fee calculation devices are distributed and processed. At this time, if the billing data distribution device and method is to calculate the billing data by distributing the billing data based on the classification criteria in the mobile communication exchange generated billing data, a plurality of billing device determines whether the billing data is suitable for the distribution In this case, unsuitable billing data must be transferred to a number of other suitable billing devices.

Therefore, the above-mentioned conventional charging data distribution apparatus and method may cause unnecessary processing and transmission load. Such unnecessary processing, transmission load, etc. become larger as the number of charge calculation devices increases.

An object of the present invention is to provide an efficient billing system by providing an efficient billing data distribution device and method in the billing system, eliminating unnecessary processing and transmission load.

Another object of the present invention is to provide an efficient distribution method in a billing data distribution device. In the above distribution method, the customer is classified into a plurality of groups using the customer information, and the customer number corresponding to the subscriber number of the billing data is determined and distributed to suit the corresponding fee calculation device.

Still another object of the present invention is to set up a billing device corresponding to each subscriber number and store it in a shared memory of the billing device, thereby distributing billing data in an efficient manner. The billing data collected from the mobile switching center is determined by referring to the shared memory as an input of the calling party number of the billing data.

According to a preferred embodiment of the present invention to achieve the above objects, the billing data distribution method of the present invention is a method for distributing billing data in a billing data distribution device combined with a mobile communication exchange and a plurality of fee calculation devices. Receiving charging data including call information and a subscriber number of a calling terminal from the mobile communication switch, wherein the call information includes information about a call start time and a call end time; And extracting a preset billing device identifier corresponding to the customer information, and transmitting the billing data to the billing device corresponding to the billing device identifier.

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

2 is a diagram showing the overall configuration of a fee calculation system according to the present invention.

Referring to FIG. 2, the total fee calculation system 370 includes one billing data distribution device 350 and a plurality of fee calculation devices 360.

The billing data distribution device 350 distributes the billing data collected from the mobile communication switch 120 to each bill calculation device 360a, 360b, ..., 360n, and transmits the billing data 360a, 360b. , ..., 360n) use the distributed billing data to perform a fee calculation for each subscriber.

The charging data distribution device 350 according to the present invention includes a collector 300, an extractor 310, a transmitter 320, and a shared memory 340.

The collection unit 300 collects billing data from each mobile communication switch 120.

The extraction unit 310 performs a function of setting a fee calculation device to distribute the collected billing data. That is, the extraction unit 310 extracts the outgoing subscriber number from the collected billing data, and refers to the shared memory 340, the rate calculation device 360a, 360b, ..., to properly distribute the collected billing data 360n).

The transmitter 320 appropriately distributes the collected billing data to the corresponding fee calculation devices 360a, 360b, ..., 360n.

The shared memory 340 functions to store a fee calculation device corresponding to the subscriber number. That is, it stores the identifier of the charge calculation device (360a, 360b, ..., 360n) corresponding to the entire subscriber number, receives the subscriber number as an input, the charge calculation device (360a, 360b, .. , 360n).

3 shows a functional module of the charging data distribution device according to the present invention.

The function module of the billing data distribution device includes a customer group classification module 375, a bill calculation device setting module 380, a bill calculation device storage module 385, a billing data collection module 390, and a billing data distribution module 395. Include.

The customer group classification module 375 forms a customer group using the customer information, and a fee calculation device is set for each group. That is, the entire subscriber number (meaning the entire customer) is classified into a plurality of groups according to the customer information. One group of customers can include multiple subscriber numbers.

In this case, the customer information may include the age of the customer, the sex of the customer, the address of the customer, the payment method of the customer, the payment method of the customer, the date of payment of the customer. For example, assuming that the customer group is classified by the means of payment of the customer, the classification by the means of payment of the customer may include various classification criteria such as payment by Giro, bank transfer, credit card payment, and the like.

The fee calculation device setting module 380 sets, for each subscriber number, a fee calculation device corresponding to each subscriber number in order to determine to which fee calculation device the billing data of the subscriber number should be distributed.

Accordingly, in the above two customer module classification module 375 and two modules of the charge calculation device setting module 380, one subscriber number will be included in one customer group, and one customer group is assigned to one charge calculation device. Is set. As a result, one fee calculation device is set for one subscriber number, and this setting is performed for the entire subscriber number.

The charge calculating device storage module 385 stores the charge calculating device corresponding to each subscriber number set in the charge calculating device setting module 380 in the shared memory of the charging data distribution device. That is, the information stored in the shared memory becomes an identifier of each subscriber number and the corresponding fee calculation device.

Shared memory is a data sharing technique among applications provided by UNIX systems, etc. The billing data distribution device uses a certain memory area of the system as shared memory, so access / read is faster than when the corresponding data is stored on the hard disk. can do.

The charging data collection module 390 collects the charging data stored in the entire mobile communication exchange to the charging data distribution device. The transmission / reception scheme used in the charging data collection module 390 may include a file transfer protocol (FTP), a file transfer, access and management (FTAM), and a transfer using a socket.

The billing data distribution module 395 reads the corresponding calling party number for all the billing data collected from the mobile communication exchange, inputs the calling party number into the shared memory, and reads the corresponding billing device identifier, and the corresponding fee. Send the billing data to the calculating device.

4A is a flowchart illustrating a process performed in a fare calculation system according to the present invention, which will be described in detail by taking an example of interaction between a mobile communication exchange, a billing data distribution device, and a fare calculation device.

First, in step 400, the entire subscriber number is classified into a plurality of customer groups according to the customer information. That is, the billing data distribution device forms a customer group using various customer information such as the sex of the customer, the address of the customer, the age of the customer, the payment method of the customer, the payment method of the customer, the date of payment of the customer. One customer group may include multiple subscriber numbers with the same kind of customer information.

The data format of the customer group is shown in FIG. 5A. The customer group may include various information, and the field items used in the present invention include a customer group identifier, a number of subscribers included in the customer group, a fare calculation device identifier corresponding to the customer group, and the like as shown in FIG. 5A. do.

For example, if the total subscriber number is classified into 42 customer groups according to the customer information such as payment means, and there are 16 fee calculation devices, the identifiers of the customer groups have values of G1 to G42, respectively. The device identifier will have a value between R1 and R16. Therefore, in step 400, 16 fee calculation devices are set up corresponding to 42 classified customer groups, and each customer group has one fee calculation device for each customer group.

Next, in step 410, a customer group corresponding to each subscriber number is set. As in the above example, the customer information is read for all subscriber numbers to determine which customer group is among the 42 customer groups. That is, in step 410, a customer group identifier corresponding to each subscriber number is set for each subscriber number using information previously set in the customer group using the customer information. 5B shows a customer group identifier corresponding to each subscriber number in the form of a table.

Next, in step 420, a fee calculation device corresponding to each subscriber number is set using the customer group identifier corresponding to the customer group and the subscriber number read in steps 400 and 410. FIG. As shown in Figs. 5A and 5B, respectively, the fare calculation device corresponding to each subscriber number is matched by using the customer group identifier corresponding to the customer group and each subscriber number. Fig. 5D shows a tariff calculation device setting corresponding to each subscriber number in the form of a table.

In step 430, the charge calculation device corresponding to each subscriber number is stored in the shared memory. That is, an address value of the shared memory is set using each subscriber number, and the toll calculation device identifier is stored in the address value. Referring to FIG. 5E for a more detailed description, the format of the shared memory divides the entire shared memory into a plurality of data areas, and assigns an address value to each data area. In addition, each data area is divided into as many segments as the total billing device. The address value is for accessing each data area and can be set using each subscriber number.

In step 440, the billing data transmission request is sent to each mobile communication exchange.

In step 450, the requested charging data is received from each mobile switching center.

In step 460, the calling party number is extracted for all the received billing data, and the billing data is transmitted to the billing device corresponding to the calling party number with reference to the shared memory.

FIG. 4B is a flowchart illustrating a dispensing method of the charging data distribution device according to the present invention, which corresponds to step 460 of FIG. 4A. Step 460 includes extracting the calling party number from the received billing data (step 460a of FIG. 4b), reading the toll calculating device identifier corresponding to the subscriber number extracted from the shared memory (step 460b of FIG. 4b), and calculating the fee Transmitting charging data (step 460c of FIG. 4B) to the corresponding billing device corresponding to the device identifier; determining whether all charging data has been processed (step 460d of FIG. 4B).

In FIG. 4B, step 460b divides the calling party subscriber number extracted in step 460a by the total number of calculating devices and sets the quotient and remainder, and then the corresponding segment of the shared memory address value corresponding to the quotient and the segment of the data area corresponding to the remainder. Find and read the fare calculation device identifier stored there.

Again, in step 470 of FIG. 4A, the actual fee calculation is performed using the billing data in each fee calculation device. Each charge calculation device is assigned to each customer group, and performs the charge calculation function only for the corresponding subscriber number. Therefore, as in the conventional billing data distribution method, in processing the billing data generated by another regional mobile communication exchange, the disadvantage of having to transmit to a suitable billing device is eliminated.

For a more accurate understanding of each step of FIG. 4A, an example will be described. In the following example, it is assumed that the total number of subscriber numbers is 10 million, the total number of charge calculation devices is 16 and the customer group is 42.

In step 400, among the 42 customer groups, the customer group G1 is set to the rate calculating device R2, the customer group G2 is set to the rate calculating device R1, and the customer groups G3 and G4 are set to the rate calculating device R3, respectively. The device identifier is assigned.

In the next step 410, the preset subscriber number 016-0234-1232 is the customer group G1, the subscriber number 016-0234-1233 is the customer group G2, and the subscriber number 016-0234-1234 is the customer group G3, the subscriber number 016-0234- Read that 1235 is customer group G4, and set up a customer group corresponding to each subscriber number.

Subsequently, in step 420, based on the information obtained in steps 400 and 410, subscriber number 016-0234-1232 denotes a charge calculation device identifier R2, and subscriber number 016-0234-1233 denotes a charge calculation device identifier R1 and subscriber number 016-. 0234-1234 matches the charge calculating device identifier R3, and the subscriber number 016-0234-1235 matches the charge calculating device identifier R3, respectively.

In step 430, in order to store the charge calculating device identifier corresponding to the subscriber number in the shared memory, the value obtained by removing the prefix value from the subscriber number is divided by the total number of the calculating device. The quotient after the division indicates the address value of the shared memory, and the remainder indicates each segment.

That is, if there are 16 total billing devices, a shared memory data area for storing billing devices corresponding to 16 subscriber numbers is allocated, and one data area has an address value. In addition, the data area is divided into 16 segments, and the fare calculation device identifier is stored in each segment. For more detailed description, Equation 1 is shown.

(Subscriber number excluding prefix) / (total number of devices counted) = quotient + remainder

For example, assume that the subscriber number is 016-0234-1232, and the corresponding billing device identifier is R2. As shown in Equation 1, if the subscriber number 0234-1232 excluding the prefix is divided by 16, which is the total number of charge calculation devices, the quotient becomes 146327, and the remainder becomes 0. Therefore, the shared memory address value corresponding to the subscriber number 016-0234-1232 is 146327 and the segment storing the toll calculation device identifier becomes the 0th segment. Accordingly, the toll calculation device identifier R2 corresponding to the subscriber number 016-0234-1232 is stored in the 0th segment of the address value 146327 of the shared memory.

Therefore, assume that the subscriber number is 016-0234-1233, and the corresponding billing device identifier is R1. The subscriber number 016-0234-1233 whose subscriber number has increased by 1 to 016-0234-1232 is 146327, and the remainder is 1 in the same manner using Equation (1). Thus, the fare calculation device identifier R1 corresponding to 016-0234-1233 is stored in the first segment of the address value 146327 of the shared memory.

That is, when the subscriber numbers 016-0234-1232 to 016-0234-1247 are divided by 16, which is the number of charge calculation devices, the shares are all 146327, and the remaining values are 0 to 15. Accordingly, the fee calculation device identifiers of the subscriber numbers 016-0234-1232 to 016-0234-1247 are stored in respective segments 0th to 15th of the address value 146327 of the shared memory, respectively.

This method of storing each data area into segments is more effective in using memory. As in the above example, if one data area is allocated to only one subscriber without dividing the data area into segments for the total number of 10 million subscribers, the total memory usage is 10,000,000 subscribers * 8 bits = 10 Mbytes. .

However, if the data area is divided into 16 segments and 4 bits are allocated to each segment, 16 segments can be set in total for each segment. Thus, the total memory used is 10,000,000 subscribers / 16 * 4 bits * 16 segments = 5 Mbytes.

The billing data distribution device stores the billing device corresponding to each subscriber number in the shared memory in the above steps (steps 400 to 430).

In step 440, a request for transmission of charging data is sent to each mobile communication exchange.

In step 450, the billing data distribution device receives the billing data requested from each mobile switching center.

In step 460, as shown in the above example, the calling party number is extracted from the received billing data. If the extracted subscriber number is 016-0234-1232, the quotient and the remainder are set by dividing the calling party number by 16, which is the number of charge calculation devices. That is, the share is set to 146327, the remainder is 0, the share is accessed as an address value, and the data area of the shared memory is accessed, and the fare calculating device identifier R2 is read from the segment corresponding to the remaining zero. Thereafter, the received billing data is transmitted to the fee calculation device R2.

Thereafter, in step 470, a plurality of charge calculation devices (16 units) perform charge calculation processing for each billing data distributed from the billing data distribution device. In the above example, billing data corresponding to subscriber number 016-0234-1232 Is processed in the rate calculation device R2.

As described above, according to the charging data distribution device and method in the mobile communication fee calculation system according to the present invention, when the charging data distribution device distributes the charging data collected from each mobile communication switch to each charge calculation device, By adjusting the number of subscriber numbers included in the customer group, distribution can be made in consideration of the load balance of each billing device.

In addition, the billing data distribution device may classify each subscriber number classified by the customer information into a customer group and allocate an appropriate fee calculation device.

In addition, since each charge calculation device can perform a charge calculation on the charge data appropriately distributed in the charge data distribution device, it is not necessary to perform the determination of the suitability of the charge data to perform the charge calculation. The unnecessary billing data transmission process is eliminated.

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.
