In particular, the present invention relates to the identification of traffic information associated with a specific subscriber and the identification of subscribers associated with specific traffic. To provide a customized interface.

In the past, many facility investments have been made in the construction of a data network to provide data services to subscribers. As a result, traffic management standards and operation functions have been advanced, and traffic analysis based on subscribers is required to establish a comprehensive analysis system of traffic data.

However, conventionally, by analyzing the traffic information of the optical ADSL network in terms of network operation and design, the actual and systematic traffic analysis focused on the actual subscribers was not properly performed.

In order to solve the problems of the prior art, the present invention enables to separate traffic collected in an optical ADSL network for each subscriber and to analyze the traffic by subscriber, region, time zone, and product. In addition, the present invention enables to analyze the traffic usage tendency of the subscriber by separately extracting the traffic associated with a predetermined subscriber

ADSL subscriber and traffic information mapping method for optical ADSL traffic analysis according to the present invention is an optical subscriber transmission device in which a plurality of subscribers are connected in a traffic collection and subscriber information mapping system for each optical ADSL subscriber. A first step of constructing a facility information DB of the FLC, a second step of constructing a facility information DB of a network access server (NAS) including a plurality of interface cards to which the FLC is connected, and a facility information DB of the FLC; A third step of mapping subscriber information related to predetermined traffic using the facility information DB of the NAS; and mapping traffic information related to a predetermined subscriber using the facility information DB of the FLC and the facility information DB of the NAS; A fourth step is included.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a structure of an optical ADSL network for applying a subscriber and traffic information mapping method according to the present invention.

In high-density areas such as apartments and buildings, or in areas competing with other operators, copper routes for existing public switched telephone network (PSTN) services can be provided to provide better quality data services and to improve investment efficiency. Instead of using them, install a large-capacity facility (ONU (Optical Network Unit) or RT (Remote Terminal)) in the area and collect them.

The OUN or RT is connected to the telephone company's facility (Host Digital Terminal (HDT) or Central Office Terminal (COT)) using a fiber optic line. Facilities such as OUN, RT, HDT, and COT are collectively referred to as Fiber Loop Carriers (FLCs).

Service for one ADSL subscriber requires the assignment of multiple devices and facilities to the subscriber.

Information on facilities allocated to subscribers in FLCs (ONU, RT and HDT, COT), which are currently accommodated by optical ADSL subscribers, can be viewed through the FLC element management system (EMS).

One FLC includes a plurality of racks, a plurality of shelves, a plurality of cards, and a plurality of ports in a hierarchical manner. You can inquire via EMS.

The traffic of all subscribers belonging to the FLC is aggregated into a single STM (Synchronous Transport Module) -1 interface and delivered to a network access system (NAS), a network access system that allows access to the cornet network, a data network operated by KT.

Each NAS has a plurality of interface cards and information about them can be viewed through NAS EMS. The NAS handles traffic from multiple FLC devices through multiple STM-1 interfaces.

In particular, since FLC and NAS use Asynchronous Transfer Mode (ATM) network, one command can be managed between ATM and VC (Virtual call) and VP (Virtual Path) between FLC and NAS STM-1 interface card. . That is, each subscriber connected to one FLC has a unique VP and VC to communicate using the STM-1 interface.

By linking with FLC EMS and NAS EMS, it is possible to know the information of FLC and NAS facilities managed by the EMS.

The traffic of the optical ADSL subscriber is measured per VP and VC on the STM-1 interface of the NAS. The traffic collector collects traffic using a simple network management protocol (SNMP). Since the traffic is collected for each STM-1 interface, traffic information of all subscribers connected to the FLC connected to the interface can be obtained.                     

The subscriber information includes the subscriber's personal information and facility information assigned to the subscriber. Facility information includes the FLC and FLC port (ONU or RT) of the telephone company for the ADSL service. It is necessary to map the traffic information extracted by the subscriber information and the traffic collector by VP and VC.

2 shows a method for building a facility information DB of the FLC. The establishment of the facility information DB includes the step of selecting the EMS of the FLC by the traffic collection and subscriber information mapping system of the optical ADSL subscriber of FIG. 1 (S220), and the equipment list of the EMS by the traffic collection and subscriber information mapping system of the optical ADSL subscriber. Inquiry step (S230), the optical ADSL subscriber-specific traffic collection and subscriber information mapping system for each FLC device included in the list rack (RACK), shelf (SHELF), card (CARD), and port connected to each device Querying the hardware information such as and recording in the FLC facility information DB (S240, S250, S260).

3 shows a method for building a facility information database of a NAS. In the process of building the facility information database, the traffic collection and subscriber information mapping system of the optical ADSL subscriber selects the EMS of the NAS (S320), and the traffic collection and subscriber information mapping system of the optical ADSL subscriber inquires the equipment list of the corresponding EMS. Step (S330), and the optical ADSL subscriber-specific traffic collection and subscriber information mapping system for all NAS devices included in the list to query the information of the interface card connected to each device to record in the NAS facility information DB (S340, S350 and S360).

4 illustrates a method of mapping traffic information related to subscriber information.

In the method, the optical ADSL subscriber-specific traffic collection and subscriber information mapping system checks the port and FLC ID of a predetermined subscriber (S510), and the optical ADSL subscriber-specific traffic collection and subscriber information mapping system is assigned to the FLC port. Checking the VP and VC (S520), checking the ID of the NAS connected to the FLC with the ID and the ID of the FLC and the interface card included in the NAS (S530), and traffic per optical ADSL subscriber The collecting and subscriber information mapping system collects traffic including the ID of the NAS, the ID of the interface card, and the same information as the VP and VC, and combines the traffic with the subscriber information (S540).

This method finds the traffic used by a particular subscriber and combines it with the subscriber information.

A particular subscriber is connected to one port included in the FLC. Therefore, when the subscriber is determined, the VP and VC allocated to the port to which the subscriber is connected can be known using the FLC facility information DB. NAS facility information DB can also be used to find the NAS interface card connected to the FLC including the port.

Therefore, if the traffic information having the VP and VC is associated with the specific subscriber, the traffic used by the subscriber can be found.

5 illustrates a method of mapping subscriber information corresponding to collected traffic.

According to the present mapping method, the optical ADSL subscriber-specific traffic collection and subscriber information mapping system checks the ID of the NAS interface card for traffic having a predetermined VP and VC (S410), and the optical ADSL subscriber-specific traffic collection and subscriber information mapping system Confirming the IP address of the FLC connected to the NAS interface card (S420), collecting traffic by the optical ADSL subscriber and subscriber information mapping system checking the ID of the FLC associated with the IP (S430), traffic by the optical ADSL subscriber Acquisition and subscriber information mapping system to check the hardware information of the FLC equipment (S440), optical ADSL subscriber-specific traffic collection and subscriber information mapping system to determine whether the ports corresponding to the VP, VC (S450, S460) And, if the port does not exist, the optical ADSL subscriber-specific traffic collection and subscriber information mapping system performs error processing (S470). Yiwu includes a step (S480) of the optical ADSL subscriber-traffic acquisition and subscriber information mapping system associated with the subscriber information corresponding to the traffic to the port.

The method finds a subscriber using the VP and VC for traffic having a predetermined VP and VC and maps the traffic information and the subscriber information.                     

The FLC and NAS facility information DB is used to know which subscriber is sending traffic having a predetermined VP and VC.

Specific VP, VC is assigned to specific port of FLC, and FLC is connected with specific interface card of NAS.

Therefore, by finding the interface card of the NAS through which the traffic has passed and searching the NAS facility information DB, it is possible to find out the FLC to which the interface card is connected, and by searching the facility information DB of the FLC, the port having the VP and VC can be determined. . However, since one port is connected to one subscriber, it is possible to know the information of the subscriber who generated the corresponding traffic.

By using the present invention, traffic can be systematically and comprehensively analyzed according to subscriber, product, region, and subscriber's disposition.

In particular, in a high demand area or in a competitive relationship with other operators, this comprehensive analysis can be used to efficiently build networks, make appropriate investments, and gain a competitive advantage over other companies.

The embodiments of the present invention are for the purpose of illustration and those skilled in the art can make various modifications and changes of the embodiments through the technical spirit of the claims, and such modifications and changes are within the scope of the claims.
