Description

Provisioning method of logical subscriber port information for connections between different users}

The present invention relates to a method of configuring subscriber port information for establishing a connection between different users, and more particularly, a network access point (hereinafter referred to as NAP) indicating an end point of a network from a communication network point of view and an access point of a network from a terminal point of view. In the configuration of NAP that logically modeled the subscriber port, the connection between different users is maintained by maintaining the connection allowance information for other users in the NAP configuration information for setting up the connection between different users (EXTRA PVC). (EXTRA PVC) The present invention relates to a method of providing a communication session processing method for selectively determining a user who can set (EXTRA PVC).

In the existing network management system, the subscriber port is configured by the operator according to the contents of the subscription and the connection admission control (CAC) is performed among the preconfigured subscriber ports when establishing the INTRA PVC. .

In this case, the connection between different users uses a dedicated line. Therefore, since separate construction is required to configure different connection networks (EXTRA NET), it takes a lot of time and money, and it is not easy to change the configuration of different connection networks.

In addition, in recent years, various network elements exist in one communication network to provide various data transfer services, so that service management devices are integrated and operated in order to efficiently manage the resources of the communication network and provide various services to customers. It is becoming. Therefore, if the allowed to set the PVC between the different users in the automated device without limitation, it is possible to set the PVC of the unwanted users can cause damage in good faith, and there is a disadvantage that can be wasted network resources.

In view of the conventional problems as described above, the present invention provides a NAP that logically modeles a subscriber port in configuring a subscriber port to allow establishment of a permanent virtual line (hereinafter referred to as PVC) between different users. The purpose of this is to prevent connection by unwanted users in advance by including NAP addresses and connection permission information of other users who allow connection in the information forming the network access point.

In order to achieve the above object, in the subscriber port information configuration method,

A first step of extracting contract information of a user who subscribes to a service and storing the subscriber port information in a user network access point (NAP) information table;

When the user information is stored, a second process of storing the connection permission information for another user to which the user wants to establish a connection is provided.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a block diagram showing the physical configuration of the subscription processing unit, communication session processing unit, network management apparatus installed in a distributed computer environment to which the present invention is applied, the subscription information is registered subscription processing unit ( 10, it is input to the subscription information receiving unit 21 in the communication session processing apparatus 20.

Subsequently, when the information is received, the information processing unit 22 in the communication session processing apparatus 20 checks the subscription information input through the subscription information receiving unit 21 and stores it in the database 24, while also calling the network management device. The unit 23 requests a service configuration to the corresponding network management devices 30 and 40 of the ATM network management device 30 and the frame relay network management device 40.

The service subscription is completed through the above process. At this time, the user requests the configuration of the NAP according to the type of service to be used. Subsequently, when NAP configuration is completed, the user may predefine NAPs of other users who allow the user to connect to the user. Such connection permission information may be stored in the database 24 of the communication session processing apparatus 20, and other user connection settings may be performed. The connection allowance information is checked in the database 24 of the city communication session processing apparatus 20, and the PVC setting is possible only when allowed.

2 is a flowchart illustrating a process of configuring a network endpoint for a user to use a service according to the present invention. When an operator gives a service subscription command through a subscription task processing apparatus 10 for a user's service subscription, a communication session is provided. The subscription information receiving unit 21 of the processing device 20 receives this command, which includes the user's contract information, information on the endpoint of the service to be provided to the user, and the like (S1).

Subsequently, when receiving the service user subscription, the information processing unit 22 of the communication session processing apparatus 20 checks whether the user has subscribed, classifies the service that the user wants to subscribe to (S2), and the corresponding service endpoint number. Contract information such as port identifier and bandwidth (BW) and information necessary for configuring an endpoint are extracted (S3).

Subsequently, the information processing unit 22 of the communication session processing apparatus 20 checks whether the extracted information is in error, and if the information is normal, requests the network management apparatus 30, 40 to configure an endpoint for service use. If an error has occurred (S4).

Subsequently, when the endpoint configuration is completed in the network management apparatuses 30 and 40, service subscription information for the user is stored in the database 24 of the communication session processing apparatus 20 (S5).

When the subscription for the service is completed according to the above process, the network endpoint is configured so that the user can set the PVC. At this time, the user can pre-specify the information such as NAP address, bandwidth, number of connections, etc. of other users who want to allow the connection, so that only the user who has allowed the user can set the PVC for his NAP. The operation process of will be described with reference to FIG.

3 is a flowchart illustrating a process of adding a NAP address and connection permission information of another user to which the user wants to allow connection according to the present invention. If user A tries to allow connection with another user B, the subscription processing unit 10 ) Transmits the request information as described above to the communication session processing apparatus 20. In this case, the connection allowance request information with the other user B is transmitted together with the bandwidth allowed when B sets PVC to A, the number of connections, and the NAP address of B (T1).

Subsequently, the communication session processing apparatus 20 receives the above request and checks the configuration information of the user A's NAP 1 (T2). If the user's NAP 1 is configured, the communication session processing apparatus 20 attempts to allow the user A's information and the connection. The NAP information of user B is respectively confirmed (T3).

As a result of the check, if there are already NAPs allowed to be connected to the information of the user A, the information and the information of the connection allowed NAP of the user B to be newly added are added. In this case, the added information includes connection allowable bandwidth and allowed connection number information (T4).

Subsequently, the contract information of the user A's NAP 1 is compared with the summed information. If the contract information of the user's NAP 1 is greater than the summed information, the information about the user B is recorded in the information table of the user A's NAP 1. Add as allowed connection information and exit.

If the sum is greater than the result of the comparison, the allowable connection cannot be added, and thus terminates immediately (T5).

For example, if user A's NAP has a contract connection number of 100 and the number of other subscribers that are currently allowed to connect is 10, when adding another user to the user A's NAP, this additional user's permission is allowed. If the number of connections is 20, the number of contract connections is 100, and the sum of the number of allowed connections and the number of connections to be added is 30, so that another user can be added to the user A's NAP.
