The present invention relates to a method and a system for generating integrated billing information for each service for using a wireless data service. In particular, when a user uses various services in one data session, the user performs differential charging for each service and performs idle time. The present invention relates to a method and system for generating integrated billing information for each service for use of a wireless data service capable of differential time billing.

The communication network technology has developed into two axes of a circuit network represented by a public switched telephone network (PSTN) and a packet network represented by the Internet. Due to the difference in communication technology, network operators generally charge the network fee by introducing a time billing policy, and packet network providers charge the network fee by introducing a packet pay-as-you-go or unlimited packet policy.

However, recently, mobile communication services such as General Packet Radio Service (GPRS), Code Division Multiple Access-2000 (CDMA-2000), and Wideband CDMA (WCDMA), which combine the characteristics of network and packet networks, have time charging policies and packet charging. The billing method was diversified by applying a mixed policy. In addition, according to the type of the terminal of the user, the type of access network or the fee system that the user subscribes to the form that can choose the desired billing method.

In this case, the user receives the requested data through the packet communication network, and the mobile communication service provider generates and manages billing data for charging the user for using the packet communication network at each time point. The generated billing data is summed at predetermined time points (for example, monthly) and billed in addition to the voice communication fee of the user.

Therefore, the mobile communication service provider must present a method for guaranteeing the transparency of the fee in order to charge the user a reasonable fee.

However, a conventional mobile telecommunication service provider generates Internet billing information (IPDR: Internet Protocol Detail Record (hereinafter IPDR)) or call detail data (CDR: Call CDR), which is billing information. However, there was a limit to generate IPDR based on usage time information and usage packet volume for the entire data session. That is, IPDR generation has not been attempted to apply differential charging for each service used by a user in a data session.

In addition, the conventional IPDR generation method has a problem in that accurate IPDR generation is not performed when transaction overlap, transaction incomplete or session incomplete occurs.

Accordingly, an object of the present invention to solve the above-described problem is to realize differential charging for each service by generating an Internet Protocol Detail Record (IPDR) integrating time charging information and packet charging information for each service used in one data session. It is to provide a method and system for generating integrated billing information for each service for using a wireless data service.

Another object of the present invention is to provide a method and system for generating integrated billing information for each service for using a wireless data service that can generate an accurate IPDR even when transaction overlap, transaction incomplete or session incomplete occurs. To provide.

Yet another object of the present invention is to provide integrated billing information for each service for using a wireless data service that can apply a separate charge policy for idle time by dividing a packet transmission time and an idle time within one data session. It is to provide a generation method and system.

In order to achieve the above objects, according to an aspect of the present invention, in a mobile communication service system comprising a data service device, a proxy server, and a billing processing device, the billing processing device is to establish a TCP session between a user terminal and the proxy server. A method of generating billing data for a user's use of a wireless data service during a connection, comprising: (a) recognizing a transaction using packet data transmitted and received between the data service device and the proxy server, wherein the transaction The transaction is a pair of one HTTP request and an HTTP response corresponding to the HTTP request; (b) generating a basic Internet Protocol Detail Record (IPDR) on a transaction basis, wherein the basic IPDR includes a start time, an end time, a quantity of packet data, and an access address of the transaction; ; Repeating steps (a) to (b) until the TCP session between the user terminal of the user and the proxy server is terminated; And generating a unified IPDR by adding the plurality of elementary IPDRs to an arbitrary service group corresponding to each of the access addresses included, and generating a unified IPDR. A system, apparatus, and record carrier are provided that enable performing the method of generating integrated billing data.

Generating the unified IPDR may comprise: recognizing the end of the TCP session; (c) determining whether there is a termination error in any transaction using the generated base IPDR; (d) redefining the start time or end time of the transaction if an end error exists; (e) classifying into a corresponding service group from among a plurality of service groups designated in advance using an access address included in the base IPDR; Performing the steps (c) to (e) for all base IPDRs generated during the connection of the TCP session; And generating a consolidated IPDR by summing service usage time for each service group, wherein the sum of the service usage time is a sum of a difference between the end time and the start time of the transactions included in the service group. .

The termination error may be generated after a start time of a transaction in which a plurality of transactions are sequentially generated during one TCP session connection and a termination time of a preceding transaction is followed by a first error in which termination of any transaction is not recognized. It can be any one of two errors.

The step of redefining the start time or the end time of the transaction may be set equal to the start time of a later transaction.

When the data service device, the charging processing device and the proxy server are located on the transmission / reception path of the packet data, the charging processing device performs the steps (a) and (b) using the packet data. Characterized in that.

When the data service device, the packet copying machine and the proxy server are located on the transmission / reception path of the packet data, and the packet copying machine and the charging processing device are independently coupled, the charging processing device is copied by the packet copying machine and transmitted. Step (a) and step (b) are performed using the duplicated packet data.

The access address may be a Uniform Resource Locator (URL).

The integrated billing data generation method for each service may include calculating a total service use time corresponding to the user during the connection of the TCP session; Calculating a connection time of the TCP session; Calculating an idle time using a difference between a connection time of the TCP session and the total service use time; And performing charging according to each of the service use time and the idle time.

The calculating of the connection time of the TCP session may include calculating a connection time of the TCP session by a difference between an end time of the TCP session connection and a start start when the end time of the TCP session connection is recognized. If the end time of the connection is not recognized and the end time of the PPP connection is recognized, the connection time of the TCP session is calculated by the difference between the end time of the PPP session and the start start of the TCP session connection, and the end of the TCP session connection When the time and the end time of the PPP connection are not recognized, the connection time of the TCP session may be calculated by the difference between the end time of the last transaction generated during the TCP session connection and the start of the start of the TCP session connection. .

The data service device includes an interworking function (IWF), a packet data serving node (PDSN), a serving GPRS supporting node (SGSN), a gateway GPRS supporting node (GPRS) Supporting Node) may be at least one.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the same reference numerals will be used for the same means regardless of the reference numerals in order to facilitate the overall understanding.

1 is a diagram schematically showing an entire system configuration for performing a method for generating integrated billing information for each service according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the mobile communication service system 120 for performing a service-specific integrated billing information generation method according to the present invention includes a base transceiver station (BTS) 125, a data service device 130, and a packet copy machine (BTS). 135, the billing processing device 140 and the proxy server 145. Of course, the mobile communication service system 120 may include a base station controller (BSC), a mobile switching center (MSC), a home location register (HLR), and a visitor location register (VLR). Obviously, the description of other components is omitted for convenience of description.

The base station 125 is a device that enables wireless communication between the user terminal 110 and the mobile communication service system 120 through a wireless communication network, and transmits and receives a signal with the data service device 130 on a transmission path. The user terminal 110 is connected to the mobile communication service system 120 through a communication network, and a plurality of content providing servers 150a, 150b, ..., 150n coupled to the mobile communication service system 120 through a communication network. The device receives specific content data (for example, a ringtone, a wallpaper, a video, etc.) from the device. The user terminal 110 may be, for example, a mobile communication terminal, a personal digital assistant (PDA), a notebook computer, or the like.

The data service device 130 is a device that enables the provision and use of a wireless Internet service in addition to a voice call network. An interworking function (IWF), a packet data serving node (PDSN), It may include at least one of a Serving GPRS Supporting Node (SGSN) and a Gateway GPRS Supporting Node (GPRS). IWF refers to a wireless data service device in a 2G network, a packet data serving node (PDSN) refers to a wireless data service device in a synchronous 3G network, and a gateway GPRS supporting node (GPRS) refers to an asynchronous 3G network. A wireless data service device in a network. Of course, if the device performs a similar function can be applied in the same manner as the above-described devices.

The packet copier 135 copies and transmits all kinds of packet data transmitted and received between the data service device 130 and the proxy server 145 to the billing processing device 140.

The billing processing unit 140 uses a packet data received from the packet copying machine 135 to perform a transaction, that is, an HTTP request and an HTTP response (HTTP request) transmitted and received between the user terminal 110 and the proxy server 145. Basic IPDR (Internet Protocol Detail Record) is generated in units of pairs), and the integrated IPDR is generated by aggregating the basic IPDR according to a predetermined criterion (eg, for each service). The billing processing unit 140 may perform billing using the basic IPDR and / or the integrated IPDR.

The proxy server 145 may be a service platform included in the user terminal 110 (for example, a binary runtime environment for wireless (BREW), a mobile explorer (ME), a KTF unified navigator (KUN), and a wireless internet platform for interoperability (WIPI). ), VOD, etc.) and a device for accessing the content providing server 150 corresponding to the corresponding service platform. The proxy server 145 may perform functions such as mediation of content data, protocol conversion, and encryption processing.

When the user terminal 110 transmits a wireless data service request, the proxy server 145 corresponds to service items provided by the predetermined content providing server 150 corresponding to the service platform provided in the user terminal 110. The menu information may be transmitted to the user terminal 110, and may be a specific HTTP request (eg, content data provision request, content data upload request, etc.) from the user terminal 110. When the case is received), the content data is received from the content providing server 150 providing the corresponding content data and transmitted to the user terminal 110 through the data service device 130.

The content providing server 150 is connected to the mobile communication service system 120 through a communication network and provides a content data requested by a user. The content providing server 150 includes a ringtone providing server, a background image providing server, a stock information providing server, and the like. There may be.

As illustrated in FIG. 1, mobile communication services such as a general packet radio service (GPRS), code division multiple access (2000), wideband CDMA (WCDMA), and the like, may include a user terminal 110 and a proxy server 145. One TCP session is established between them. Therefore, even if a user transmits an HTTP request to the plurality of content providing servers 150, all HTTP requests are transmitted to the corresponding content providing server 150 via the proxy server 145 and the content providing server 150. The HTTP response received from) is also transmitted to the user terminal 110 via the proxy server 145.

That is, in the mobile communication service environment, when the user terminal 110 receives content data from the plurality of content providing servers 150, a plurality of TCP sessions separated by each content providing server 150 or a service are generated, and each session It has a different configuration from the conventional wired Internet environment in which the service form is different for each.

Therefore, the billing processing unit 140 installed between the user terminal 110 and the proxy server 145 by the packet extraction method is one TCP rather than a plurality of TCP sessions divided according to the type or service type of the content providing server 150. Detect multiple web service usage data on the session.

2 is a flowchart illustrating a method of generating integrated billing information for each service according to an exemplary embodiment of the present invention. FIG. 3 is a diagram illustrating a wireless data service usage flow according to an exemplary embodiment of the present invention. In accordance with one preferred embodiment of the present invention, a flowchart illustrating a method for eliminating an error in generating an integrated IPDR is shown.

Referring to FIG. 2, the billing processing unit 140 receives the duplicate packet data from the packet copier 135 in step 210, and proceeds to step 215, in which the underlying IPDR (Internet Protocol Detail Record, Internet) is executed on a transaction basis. Accounting information). In the present invention, a transaction refers to each HTTP request and HTTP response pair transmitted and received between the user terminal 110 and the proxy server 145 in one TCP session. Within the basic IPDR, the start time and end time of the transaction (eg, the start time and end time of the HTTP request, the start time and end time of the HTTP response), the size of the packet data composing the transaction, and the content providing server 150 The access address (eg, all lists of URLs used in each transaction), user information, reason for termination of Internet use (eg, normal termination, abnormal termination), and the like.

There is no limitation on how the charging processing device 140 recognizes that an arbitrary HTTP request and an arbitrary HTTP response are a pair. However, here, for convenience of understanding, only two methods in which the charging processing device 140 may recognize a pair of HTTP request / response will be described.

First, the hash processing unit 140 and the proxy server 145 generate a hash value using the same hash algorithm, respectively, and then the HTTP processing unit 140 determines whether the hash values match. The method of recognizing a pair of HTTP responses can be applied. Of course, pair recognition of the HTTP request and the HTTP response as whether the hash values match is performed in a separate information analysis device (not shown), and then the billing processing device 140 using the pair recognition information provided from the information analysis device. May generate a base IPDR on a transaction basis.

Briefly, a method of recognizing an HTTP request / response pair as a match of hash values is as follows.

When an HTTP request for arbitrary content is transmitted from the user terminal 110, the HTTP request is transmitted to the proxy server 145 via the data service device 130, the packet copying machine 135, or the like. The charging processing device 140 (or the information analyzing device, which is the same below) receives the replicated replication HTTP request from the packet copier 135, extracts the URL from the received replication HTTP request, and then extracts the extracted URL and the predetermined hash algorithm. (Hash Function, for example, MD5, SHA-1, HAS-160, etc.) to generate a first hash value. The proxy server 145 extracts a URL from the received HTTP request and then generates a second hash value using the extracted URL and a predetermined hash algorithm. The proxy server 145 transmits the received HTTP request to the corresponding content providing server 150, and corresponds to the HTTP request (eg, stock information providing request) from the content providing server 150. Receive a raw HTTP response containing content data. Since the proxy server 145 can recognize which HTTP request the received raw HTTP response corresponds to, the second hash value generated for the corresponding HTTP request as a new field value in the header of the raw HTTP response. Generate the transform HTTP response by inserting The proxy server 145 transmits the converted HTTP response to the user terminal 110 through the communication network, and in this process, the packet copier 135 duplicates the converted HTTP response and replicates the converted HTTP response. Transmit to 140. The charging processing unit 140 extracts the second hash value inserted into the header field of the received replication conversion HTTP response, and determines whether the first hash value and the second hash value match. If there is a match, the translated HTTP response is considered to be a pair with the HTTP request corresponding to the first hash value.

Next, when the proxy server 145 receives an HTTP response corresponding to the HTTP request, the proxy server 145 inserts charging information for the HTTP request and the HTTP response into the HTTP response and transmits the data to the data service device 130. to be. Applying this method, the billing processing unit 140 receives the duplicate packet data of the HTTP response including the charging information from the packet copying machine 135 so as to use the received duplicate packet data to pair the HTTP request and the HTTP response (Pair). Recognition and charging for the packet data can be performed.

The method of recognizing HTTP request / response pairs and generating charging data by modifying the header information of the HTTP response of the proxy server 145 will be described briefly as follows.

When an HTTP request for arbitrary content is transmitted from the user terminal 110, the HTTP request is transmitted to the proxy server 145 via the data service device 130, the packet copying machine 135, or the like. The proxy server 145 transmits the received HTTP request to the corresponding content providing server 150, and corresponds to the HTTP request (eg, stock information providing request) from the content providing server 150. Receive a raw HTTP response containing content data. The proxy server 145 extracts HTTP header information from the raw HTTP response, and charges base data (e.g., the number of bytes of the HTTP request, the number of bytes of the HTTP response, and the number of per second) in the extracted HTTP header information. And insert the access address, subscriber information, etc. of the content providing server 150 to generate a converted HTTP response. The proxy server 145 has already received a session related information about which data request (HTTP Request) has been received from the user terminal 110, which content providing server 150 has been transmitted to the request, etc. Since it manages, this charging basic data can be easily inserted in an HTTP header. Thereafter, the proxy server 145 transmits the converted HTTP response to the user terminal 110 via the packet copier 135, the data service device 130, or the like. The packet copy machine 135 duplicates the received converted HTTP response and transmits the duplicate converted HTTP response to the charging processing device 140. The charging processing device 140 performs charging for the pair of the HTTP request and the HTTP response by using the charging basic data inserted in the header of the replication conversion HTTP response. This is because the billing basic data includes the number of bytes of the HTTP request, the number of bytes of the HTTP response, the access address of the content providing server 150, and the like, and the charging processing device 140 separately charges the HTTP request and the HTTP response. There is no need to do it. In addition, since the proxy server 145 configures a pair of the HTTP request and the HTTP response, charging can be performed only when a normal HTTP response exists.

Of course, in addition to this, there may be various methods in which the billing processing unit 140 recognizes any HTTP request and any HTTP response in pairs. In the following description, it is assumed that the billing processing unit 140 constitutes a transaction by recognizing an arbitrary HTTP request and an arbitrary HTTP response as a pair.

In step 220, the charging processing device 140 classifies the base IPDR generated in step 215 by service group. 3 illustrates a wireless data service usage flow of any user. The mobile communication service provider may classify various services into a plurality of service groups (for example, service group classification based on a URL) according to a service plan. Hereinafter, a description will be given on the assumption that the domain names of the access addresses (for example, URLs) are the same and classified into the same service group. In addition, it is assumed that the wireless data usage flow illustrated in FIG. 3 is a case where a user uses wireless data services of a plurality of service groups such as service group A, service group B, and service group C.

The billing processing unit 140 aggregates the basic IPDRs classified into any service group in step 225 to generate an integrated IPDR, and proceeds to step 230 to perform charging using time information and IPDR of the TCP session.

Hereinafter, a process of generating an integrated IPDR and performing charging will be described in detail with reference to FIGS. 3 and 4. As described above, FIG. 3 assumes a case where a user uses a plurality of services (that is, service group A, service group B, and service group C) in one TCP session connected between the user terminal 110 and the proxy server 145. One wireless data usage flow is illustrated. A method of generating an integrated IPDR normally even when the mobile communication network is unstable or the user terminal 110 performs abnormal operation using the wireless data usage flow illustrated in FIG. 3 and the flowchart of FIG. 4 will be described.

Referring to FIG. 4, in step 410, the charging processing device 140 determines whether t _end, which is the end time of the PPP connection, is recognized. If t _end is recognized, flow proceeds to step 415 where t _end is set to t _FIN . However, if t _end is not recognized, the flow proceeds to step 420 where t _end , which is the end time of the last transaction before the end of the TCP session, is set to t _C2 . In general, in the mobile communication service system, t _start and t _end , which are the start time and end time of PPP, can be recognized with high precision. In addition, the accounting processing unit 140 may determine t _{syn, which} is a start time of the TCP session. However, due to instability of the mobile communication network and non-standard operation of the user terminal 110, a packet for recognizing t _FIN does not occur, and a case in which t _FIN does not exist (for example, grows to infinity) may occur. Because there is.

In step 425, the billing processing unit 140 determines whether there is a transaction in which termination error occurs among transactions generated during the TCP session connection. When the charging processing device 140 determines that the transaction is terminated, for example, when the termination of any transaction is not recognized, the termination of any transaction may occur after the start time of the next transaction. Can be. If it is determined that there is no termination error, the flow proceeds to step 435. In general, the wireless data usage flow illustrated in FIG. 3 must satisfy a relationship as shown in Table 1 below in order that an error does not exist in a plurality of transactions existing during a TCP session.

Table 1. Normal end conditions for transactions

transaction Start time End time relation First transaction 310 t _a1 t _a2 t _syn -t _a1 Second transaction 320 t _b1 t _b2 t _a2 -t _b1 Third transaction (330) t _a3 t _a4 t _b2 -t _a3 Fourth transaction (340) t _b3 t _b4 t _a4 -t _b3 Fifth Transaction 350 t _a5 t _a6 t _b4 -t _a5 Sixth transaction 360 t _c1 t _c2 t _a6 -t _c1

In addition, "t _FIN -t _syn -service group A usage time (that is, (t _a2 -t _a1 ) + (t _a4 -t _a3 ) + ( t _a6 -t _a5 )) + Service Group B Usage Time (i.e. (t _b2 -t _b1 ) + (t _b4 -t _b3 )) + Service Group C Usage Time (ie (t _c2 -t _c1 )) " Must be satisfied. This generally means that there is an idle time between each transaction.

However, if it is determined that there is an end error, the flow proceeds to step 430 to redefine the transaction end time. First, when the end of any transaction in the TCP session is not recognized, it may be defined that the end time of the next transaction is the same as the start time of the next transaction. For example, when the end of the third transaction 330 is not recognized, the end time of the third transaction 330 (that is, t _a4 ) is equal to the start time of the fourth transaction 340 (ie, t _b3 ). The same can be defined as t _a4 = t _b3 .

Next, when the end of any transaction occurs after the start time of the next transaction, the end time of the transaction may be redefined to the start time of the next transaction according to the charging policy. For example, if the end of the first transaction 310 occurs after the start time of the second transaction 320 (ie, t _b1 ), the end time of the first transaction 310 (ie, t _a2 ) is the second time. You can redefine the same as the start time of the transaction (that is, t _b1 ) (t _a2 = t _b1 ).

Thereafter, in step 435, the billing processing device 140 adds up usage time for each service. That is, as described above, the billing processing apparatus may classify the service group corresponding to each transaction by using the access address included in each transaction, and add up the use time of the transaction for each classified service group.

In operation 440, the accounting processing unit 140 calculates an idle time. Idle time refers to the time that a TCP session is connected but not occupied by a transaction as described above (that is, t _IDLE = (t _FIN -t _syn )-(service class A usage time + service group B usage time + service group C usage) Time)).

In operation 445, the charging processing device 140 performs charging for service usage (that is, data service usage time and content usage fee) and the calculated idle time. Since the billing processing device 140 according to the present invention can accurately calculate the service usage time and the idle time, an optimal billing corresponding to the user's wireless data service usage is possible. That is, the present invention can solve the problem that expensive charging is made even during idle time when a user does not request or receive content data during a conventional TCP session.

In the following description of a method of generating integrated billing information for each service for using a wireless data service according to the present invention, a plurality of transactions generated during a TCP session are classified by service group based on a connection address and then included in a specific service group. The description will focus on a method of performing charging by summing the usage times of a plurality of transactions. That is, it is assumed that the usage fee per hour (that is, the communication network fee) or the content usage fee (that is, content fee) are equally applied to each service group.

However, in some cases, even if the transaction is included in the same service group, the specific transaction is charged only for the network usage fee (eg, the content data retrieval service), and the specific transaction is charged for the network usage fee and the content usage fee (eg, content Data download service).

In addition, although a plurality of transactions occurred during one TCP session, a specific transaction may be charged according to the usage time, and another transaction may be charged according to the packet usage.

However, it is apparent that the above-described service aggregation method for each service group may be similarly applied to these cases. In this case, for example, a detailed service group (for example, an hourly billing service, a packet billing service, a content usage fee charging service, etc.) subordinate to a service group determined for each access address may be sufficient, and thus description thereof will be omitted. Of course, it is obvious that various service grouping methods for charging a user's use of wireless data service according to various fee products may be applied.

In addition, only the case where the configuration of the service-specific integrated billing information generation system according to the present invention includes the packet copying machine 135 has been described, and in this case, the billing processing device 140 is configured from the packet copying machine 135. The received duplicate packet data was used to generate the base IPDR and the integrated IPDR (see FIG. 1). However, the charging processing unit 140 is located at the position of the packet copying machine 135 in the system configuration diagram of FIG. 1, and the packet data transmitted and received between the data service device 130 and the proxy server 145 is charged. In the case of via, the same method may be used to generate the basic IPDR and the integrated IPDR. That is, the charging processing device 140 generates the basic IPDR and the integrated IPDR using the packet data transmitted and received via the packet processing device 140. When the packet copying machine 135 is not included, a method of generating the IPDR using the packet data by the charging processing device 140 may be easily implemented by those skilled in the art, and thus description thereof will be omitted.

As described above, the method and system for generating the integrated billing information for each service for the use of the wireless data service according to the present invention is an Internet Protocol Detail Record in which time billing information and packet billing information are integrated for each service used in one data session. ), It is possible to realize differential charging for each service.

In addition, the present invention can generate an accurate IPDR even when transaction overlap, transaction incomplete or session incomplete occurs.

In addition, the present invention may apply a separate charge policy for idle time by dividing packet transmission / reception time and idle time within one data session.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
