Abstract

PURPOSE: A mapping method between an IPDR(IP Data Record) and a CDR(Calling Data Record) on a dynamic Internet protocol is provided to process billing by combining an MN(Mobile Node)'s IP information and time information in an IPDR created from a router, a call time in a CDR, and the time that a DHCP granted the IP to the MN. CONSTITUTION: If an MSC(Mobile service Switching Center) generates a CDR, a mediation part receives it and judges whether it is a data call(S10,S11). In case that it is a data call, the mediation part confirms the time used and the subscriber(S13,S14). Then the mediation part collects a DHCP log, executes filtering dependent on a CDR ID for a DHCP server log and filtering dependent on CDR time for the DHCP server log, and judges whether the collected log is the relevant subscriber's log(S15,S16). In case that the collected log is the relevant subscriber's log, the mediation part judges whether the time used is matched with the time collected(S17). If the time used is matched with the time collected, the mediation part records the used IP and the IP-used time in the CDR(S18,S19), stores the mapping CDR for billing(S20), and transmits it to the next system(S21).

Description

MAPPING METHOD FOR IP DATA RECORDING AND CALL DATA RECORDING ON DYNAMIC INTERNET PROTOCOL}

The present invention relates to a mapping method between IP data recording and call data recording on a dynamic Internet protocol. In particular, an IP of each mobile node (MN) is connected to a dynamic host configuration protocol (DHCP). In the case of dynamically assigning the data using the MN, the IP of the MN in the IPDR (IPDR) generated by the router for charging according to the capacity of the packet, the time used and the Mobile Service Switching Center, MSC) The present invention relates to a mapping method between IP data recording and call data recording in a dynamic Internet protocol that combines the call time in a call data record (CDR) and the DHCP server to assign an IP to a corresponding MN.

In the related art, the subscriber information, the type of service used, and the time of use are extracted through the CDR issued by the MSC, and then billing according to the service use time is performed through the extracted call information.

That is, after extracting the subscriber information, the type of service and the time of use from the CDR of the MSC, the type of the service is checked through the extracted service to determine whether data is charged. Thereafter, the billing frequency is checked through the extracted usage time, and the billing rate is calculated after checking the billing rate through the extracted user information.

However, the conventional technology also includes the time when the network traffic (traffic) by the subscriber does not occur when using the data service in the billing time, it is not possible to calculate the exact charge for the service use, and also to increase the capacity according to the network traffic analysis There was a problem that the basic data required for the back cannot be built correctly.

Accordingly, the present invention has been made to solve the above-mentioned conventional problem, and the IP information of the MN in the IPDR generated in the router for charging according to the capacity of the packet and the time information passing through the router with the corresponding IP How to handle charging by checking packet capacity used by MN by combining call time in CDR created by MSC and DHCP server managing dynamic IP assignment for MN by MV time and IP information. The purpose is to provide.

1 is an exemplary view showing an operation flow of the present invention.

2 is an exemplary view showing a processing procedure for charging according to FIG.

In order to achieve the above object, a mapping method between IP data recording and call data recording on the dynamic Internet protocol according to the present invention includes a first method of determining a data call when receiving a call data record (CDR) of a mobile service switching center (MSC). Steps;

A second step of confirming usage time and subscriber according to the determination result of the first step, collecting a dynamic host configuration protocol log (DHCP log), and then determining the login value of the corresponding subscriber;

A third step of determining whether the use time and the collected use time correspond to each other according to the determination result of the second step;

According to the determination result of the third step, recording the use IP (IP) and the use time in the CDR, characterized in that the fourth step of storing the charging mapping CDR and then transmitting it to the next system.

Hereinafter, an operation process of an embodiment according to the present invention will be described with reference to the accompanying drawings.

Figure 1 is an exemplary view showing the operation flow of the present invention, Figure 2 is an exemplary view showing a processing procedure for charging according to Figure 1, as shown in the call request from the subscriber MSC checks the call When a subscriber accepts a call and an IP request is received from the subscriber, the DHCP server checks the available IP, assigns an available IP, and records a log.

Accordingly, when the subscriber checks the IP and uses the data service and then requests the IP termination, the DHCP server confirms the termination of the IP usage, records the IP termination log, and then sends the termination confirmation to the user. A call termination request is made, and the MSC confirms termination and allows termination to terminate the call.

Subsequently, when the CDR is generated in the MSC as shown in FIG. After deciding whether to charge the data by extracting the type and time of use service, checking the type through the extracted service, checking the billing frequency through the extracted use time, and checking the billing rate through the extracted user information Calculate (S12).

However, if the determination result of the step (S11) is a data call, the corresponding usage time and subscriber confirmation (S13 ~ S14), and then collect the dynamic host configuration protocol log (DHCP log) according to the CDR ID for the DHCP server log After performing filtering and filtering according to the CDR time of the DHCP server log (S15), the login value of the corresponding subscriber is determined (S16).

As a result of the determination in step S16, if the subscriber is the same, it is determined whether the usage time and the collected usage time match (S17). If the determination result is matched, the usage IP and the IP usage time are recorded in the CDR. (S18 ~ S19), after storing the charging mapping CDR (S20), and transmits it to the next (nill) system, such as billing (Billing) (S21).

That is, the CDR generated by the MSC and the log generated by the DHCP server are mapped using the ID and time information of the MN, and the IP assigned by the DHCP server to the MN, the grant time for the IP, and the MN are assigned to the DHCP. After checking the packet capacity for each MN in the IPDR generated by the router using the time information returned from the IP, the data packet usage and time for each MN are calculated on the dynamic IP.

As described above, the mapping method between the IP data recording and the call data recording in the dynamic Internet protocol of the present invention can be used for billing processing for a service (for example, a still image cartoon service, etc.) in which a large amount of data is continuously generated. It is possible to check the network usage capacity of each service user, and also to check the IP capacity, thereby effectively using IP resources.
