Description

Method for managing subscriber of system matching call manager and gatekeeper}

The present invention relates to a system in which a gatekeeper and a call manager are matched. More specifically, the present invention relates to an H.323 in a gatekeeper that is matched with a call manager that manages a general public telephone network and Internet phone call processing functions. The present invention relates to a subscriber management method of a system in which a call manager and a gatekeeper are integrated to efficiently manage an endpoint.

In case of accessing through gatekeeper in Voice over Internet Protocol (VoIP) network, it is important protocol to implement basic interface between endpoint and gatekeeper such as terminal gateway, multipoint control unit (MCU), etc. This is RAS (Registration / Admission / Status).

The RAS is also a protocol that is essential and essential for the server to operate and control the client and monitor the status to reflect the operation and control. The gatekeeper is a server, and the endpoints are clients.

Among RAS signals, registration is the process of registering the client's presence as a client with a gatekeeper whose endpoint is a server, and Admission is whether the endpoint complies with the rules of H.323 and the corresponding zone in the gatekeeper. It is the process of checking and granting access to the VoIP network, and Status is the process by which the endpoint periodically reports its information and current status to the gatekeeper.

For reference, the H.323 rule checks whether the endpoint is a gatekeeper's registration ID AliasName (alias: physical address) with another endpoint, and the zone's rule checks whether the endpoint is registered with the gatekeeper. Say.

Admission is divided into no-control mode for all endpoints and pre-defined mode only for predefined endpoints.

The no-control mode is practically impossible for commercial use and is used only for experimental or research purposes. The predefined mode is mainly serviced. The user profile fields of H.323 include fields such as Alias_name, E.164Number, and Email_address. There is a hassle of having to fill in all of these fields during initialization.

This approach also has the problem of confusion in specifying the endpoint's IP address in the gatekeeper's user profile database.

Accordingly, the present invention has been made to solve the above problems, the subscriber telephone number held in the call manager to download to the gatekeeper and H.323. By automatically assigning IP addresses used by the endpoints in the order of initialization, subscriber management of the call manager and gatekeeper-matched system enables users (subscribers) to enter user information efficiently and manage subscribers efficiently. The purpose is to provide a method.

In order to achieve the above object, a method for managing subscribers in a system in which a call manager and a gatekeeper are matched includes planning for a telephone number to be used in the entire system; Preparing and entering a user profile database for the planned telephone number in the call manager; Downloading a user profile database for the entered telephone number from the call manager to the gatekeeper; Deciding a range of IP addresses to use at the endpoint and sending it to the DHCP server; Automatically allocating an IP address at a DHCP server upon endpoint initialization; Transmitting a registration and permission request signal to a gatekeeper at a pre-entered telephone number when the endpoint boots up; The gatekeeper compares and determines whether the telephone number received from the endpoint is a telephone number belonging to the user profile database downloaded from the call manager; Outputting an authentication signal when the phone number belongs to a user profile; And outputting a reject signal if the phone number does not belong to the user profile.

The step of automatically allocating an IP address when the endpoint is initialized is characterized in that the IP address is allocated according to the booting order of the endpoint.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

1 is a block diagram of a system in which a general gatekeeper and a call manager are used to implement the present invention.

As shown in FIG. 1, the call managers 0 to 7 (1 to 71), the gatekeeper 110, and the Internet phones 100 to n corresponding to the H.323 endpoint are configured in a LAN environment. The call managers 1 to 71 collectively control calls (calls) transmitted and received through the private exchanges 0 to 7 (2 to 72).

Under these circumstances, the gatekeeper 110 can accommodate up to eight nodes, i.e. up to eight nodes, with private exchanges 0-7 (2-72), and the private exchanges 2-72 have respective gateways 0-7 (3-73). Call service is achieved through.

The IP address is automatically assigned according to the endpoint initialization through the Dynamic Host Configuration Protocol (DHCP) server 120.

With this configuration, the operation according to the present invention will be described.

FIG. 2 is a diagram illustrating a network connection registration / authorization procedure of an H.323 endpoint in a call manager and gatekeeper matching system according to the present invention, and FIG. 3 is a diagram illustrating a call manager and a gate according to a preferred embodiment of the present invention. This is a flowchart of subscriber management method in keeper-matched system.

1 to 3, the call manager 1 to 71 first establishes a plan for a telephone number to be used at an endpoint of the entire system (S11), and then establishes a user profile along with the established telephone number (S11). profile) prepare and input the database (telephone number, e-mail number, etc.) (S12).

In this process, each endpoint is assigned a phone number to be used by the terminal from the call manager's administrator.

The call manager downloads the input database to the gatekeeper 110 (S13), determines the range of allocable IP addresses to be used by the endpoints of the entire system, and sends it to the DHCP server 120 (S14).

DHCP server 120 allocates the IP address in the order that the endpoint is initialized (S20).

After the endpoint is booted (initialized) and assigned an IP address (S30), the endpoint transfers Registration ReQuest (RRQ) and admin ReQuest (ARQ) to the gatekeeper 110 as a pre-assigned telephone number (E.164Number). It transmits (S40).

If the gatekeeper (S40) is a phone number belonging to the user profile database downloaded from the call manager (S50) and sends a signal of authentication (RCF / ACF: Registration ConFirm / Admin ConFirm) (S61), if the phone number does not belong (S50) ) Sends a rejection signal (RRJ / ARJ: Registration ReJect / Admin ReJect) (S62).

In this case, the IP address is assigned to each endpoint in advance by the DHCP server so that it can be used in the entire system. Therefore, the gatekeeper needs to distinguish only the telephone numbers of the endpoints.

Although the preferred embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that the present invention may be modified without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Therefore, changes in the future embodiments of the present invention will not be able to escape the technology of the present invention.

As described above, according to the present invention, the subscriber management policy between the gatekeeper and the call manager can be efficiently performed, and the IP address is automatically assigned according to the order in which the endpoints are initialized. It provides convenience to users, and maintains accurate synchronization between server and client, thereby reducing the possibility of problems in system operation.
