Abstract

PURPOSE: A manual mode and an automatic mode of an SIP-H323 interworking system are provided to perform a mapping function between protocols in an SIP network or an SIP terminal or in an H.323 network or an H323 terminal, thereby carrying out call setting, changing, and completing functions between entities. CONSTITUTION: When an SIP UA(User Agent) is registered in an SIP-H323 interworking system as a client for deciding whether to receive a call setup request, the SIP-H323 interworking system registers SIP UA information in an H323 gatekeeper. If an H323 endpoint is registered in the SIP-H323 interworking system, the SIP-H323 interworking system registers H.323 endpoint information in an SIP server. The SIP UA is registered by selecting an automatic mode while the SIP UA information is registered in the H.323 gatekeeper.

Description

에스아이피-에이치323 연동시스템의 수동모드와 자동모드{ Manual Mode and Automatic Mode of SIP-H.323 Interworking System}Manual Mode and Automatic Mode of SIP-H.323 Interworking System

본 발명은 SIP기반 서비스와 H.323기반 서비스 사이의 호환성을 제공하는 SIP-H.323 연동 시스템 구현에서 시스템의 환경설정이 수동모드인 경우와 자동모드인 경우에 관한 것이다. SIP-H.323 연동 시스템은 아직 국내에서는 구현된 것이 없다.The present invention relates to a case where the system configuration is a manual mode and an automatic mode in a SIP-H.323 interworking system implementation providing compatibility between a SIP-based service and an H.323-based service. The SIP-H.323 interworking system has not been implemented in Korea yet.

SIP-H.323 연동 시스템은 SIP기반의 네트워크와 H.323기반의 네트워크 사이에 존재하여 SIP와 H.323 프로토콜 사이의 변환 기능을 수행하는 시스템으로서 빠른 호 처리와 많은 메시지 처리가 필요하다.SIP-H.323 interworking system exists between SIP-based network and H.323-based network to perform conversion function between SIP and H.323 protocol. It requires fast call processing and many message processing.

제 1도는 SIP-H.323 연동 모델1 is a SIP-H.323 interworking model

제 2도는 SIP-H.323 연동 시스템 내부 구조2 is the internal structure of the SIP-H.323 interworking system

제 3도는 수동모드로 설정된 환경파일의 일부3 is a part of the environment file set to manual mode.

제 4도는 자동모드로 설정된 환경파일의 일부4 is a part of the configuration file set to the automatic mode

SIP-H.323 연동 시스템은 SIP를 사용하는 네트워크 또는 단말과 H.323 을 사용하는 네트워크 또는 단말 사이에 존재하여 프로토콜간의 매핑 기능을 수행함으로써 서로 다른 표준을 사용하는 엔티티들 상호 간에 호 설정 및 변경 그리고 종료 기능을 수행할 수 있게 하는 시스템이다.SIP-H.323 interworking system exists between network or terminal using SIP and network or terminal using H.323 to perform mapping function between protocols to establish and change call between entities using different standards. It is a system that can perform a shutdown function.

SIP-H.323 연동 시스템은 4가지 모델을 가지고 있는데 첫 번째 모델은 SIP UA와 H.323 Endpoint만이 네트워크상에 존재하는 모델이고 두 번째 모델은 SIP UA, H.323 Endpoint, SIP Server가 존재, 세 번째 모델은 SIP UA, H.323 Endpoint, H.323 게이트웨이가 존재, 네 번째 모델은 SIP UA, H.323 Endpoint, SIP Server, H.323 게이트웨이가 존재하는 모델이다.The SIP-H.323 interworking system has four models. The first model includes only SIP UA and H.323 endpoints on the network, and the second model includes SIP UA, H.323 endpoints, and SIP servers. The third model is SIP UA, H.323 Endpoint, H.323 Gateway, and the fourth model is SIP UA, H.323 Endpoint, SIP Server, H.323 Gateway.

SIP-H.323 연동 시스템은 프로토콜간 매핑 기능의 수행을 위해 SIP 프로토콜 스택과 H.323 프로토콜 스택을 이용하며 연동 시스템으로서의 기능을 수행하기 위해 SIP 처리 모듈과 H.323 처리 모듈, 그리고 두 프로토콜 모듈을 제어하기 위한 제어모듈로 나뉜다.The SIP-H.323 interworking system uses the SIP protocol stack and the H.323 protocol stack to perform the inter-protocol mapping function, and the SIP processing module, the H.323 processing module, and the two protocol modules to perform the functions as the interworking system. It is divided into control module for controlling

제어모듈은 메시지 매핑 모듈, 미디어 포맷 변환 모듈, 주소 변환 모듈로 구성된다.The control module consists of a message mapping module, a media format conversion module, and an address conversion module.

이때 H.323 프로토콜 스택은 환경설정 파일을 가지고 있고 이 파일 안에 등록에 관련된 변수를 수동모드 또는 자동모드로 설정하는 것에 따라 SIP-H.323 연동 시스템을 다르게 구현할 수 있다.At this time, H.323 protocol stack has configuration file and SIP-H.323 interworking system can be implemented differently by setting variable related to registration in manual or automatic mode.

SIP-H.323 연동 시스템의 절차는 SIP UA에서 H.323 Endpoint로 호 설정을 시도하는 경우와 H.323 Endpoint에서 SIP UA로 호 설정을 시도하는 경우로 구분될 수 있으며 SIP 단말과 H.323 단말은 호 설정 요청 전에 SIP Server와 H.323 게이트키퍼의 존재유무에 따라 SIP-H.323 연동 시스템에 단말을 등록해야 한다.The procedure of the SIP-H.323 interworking system can be divided into the case of attempting call setup from SIP UA to H.323 endpoint and the case of attempting call setup from H.323 endpoint to SIP UA. Before the call establishment request, the terminal must register the terminal in the SIP-H.323 interworking system according to the existence of the SIP Server and the H.323 gatekeeper.

호 설정 요청에 대한 중계 기능을 수행하는 H.323 게이트키퍼와 SIP Server가 동시에 네트워크상에 존재할 때 SIP-H.323 연동 시스템을 구현하는 경우 H.323 프로토콜 스택의 환경 설정 파일을 1개나 아닌 2개를 사용하는 것이다.If you implement a SIP-H.323 interworking system when an H.323 gatekeeper and a SIP server exist on the network at the same time, performing a relay function for a call setup request, the configuration file of the H.323 protocol stack is not one or two. Is to use a dog.

첫 번째 환경파일은 수동모드로 설정이 된 것이고 두 번째 환경파일은 자동모드로 설정이 된 것이다. [도 3]에서 보면 manualRAS 변수가 있는데 이것을 설정하면 수동모드가 되는 것이고 [도 4]에서 보듯이 manualRAS 변수가 없으면 자동모드로 설정이 되는 것이다.The first configuration file is set to manual mode and the second configuration file is set to automatic mode. In Figure 3, there is a manualRAS variable, which is set to manual mode, and as shown in FIG. 4, if there is no manualRAS variable, it is set to automatic mode.

환경파일을 수동모드로 설정하면 SIP-H.323 연동 시스템에서 필요에 맞게 수동적으로 처리할 수 있도록 구현을 할 수가 있다.If the environment file is set to manual mode, it can be implemented to be manually processed according to the needs of the SIP-H.323 interworking system.

반면에 환경파일을 자동모드로 설정하면 SIP-H.323 연동 시스템에서는 그 부분에 관해서는 특별한 구현이나 관리가 필요하지 않게 된다.On the other hand, if the environment file is set to automatic mode, the SIP-H.323 interworking system does not need special implementation or management for that part.

호 설정을 요청하거나 호 설정 요청에 대한 수락 여부를 판단하는 클라이언트로서의 SIP UA가 서비스를 받고자 SIP-H.323 연동 시스템에 등록을 하면 SIP-H.323 연동 시스템은 자신한테 등록된 SIP UA를 대신해서 H.323 게이트키퍼에 SIP UA 정보를 등록한다.When a SIP UA as a client requesting call establishment or determining whether to accept a call establishment request registers with a SIP-H.323 interworking system to receive service, the SIP-H.323 interworking system replaces the SIP UA registered with itself. Register the SIP UA information with the H.323 gatekeeper.

또 호 설정을 요청하거나 호 설정 요청에 대한 수락여부를 판단하는 클라이언트로서의 H.323 Endpoint가 서비스를 받고자 SIP-H.323 연동 시스템에 등록을 하면 SIP-H.323 연동 시스템은 자신한테 등록된 H.323 Endpoint를 대신해서 SIP Server에 H.323 Endpoint 정보를 등록한다.If the H.323 endpoint as a client requesting call establishment or determining whether to accept the call establishment request registers with the SIP-H.323 interworking system to receive service, the SIP-H.323 interworking system registers the Register H.323 endpoint information in SIP Server on behalf of .323 endpoint.

이때 SIP UA가 SIP-H.323 연동 시스템에 등록을 해서 SIP-H.323 연동 시스템이 SIP UA를 H.323 게이트키퍼에 등록할 때 H.323 프로토콜 스택에 대한 환경 파일 중에 자동모드를 선택해서 등록을 한다. 호 설정과는 상관없이 중간에 다른 SIP UA 등록 메시지를 받아서 처리할 수 있어야 하므로 자동모드인 환경파일로 처리를 한다.At this time, when SIP UA registers with SIP-H.323 interworking system and SIP-H.323 interworking system registers SIP UA with H.323 gatekeeper, it selects automatic mode among environment files for H.323 protocol stack. Register. Regardless of call setting, it should be able to receive and process other SIP UA registration messages in the middle.

반면에 H.323 Endpoint가 SIP-H.323 연동 시스템에 등록이 될 때는 SIP-H.323 연동 시스템은 수동모드인 환경파일을 선택해서 처리한다. SIP-H.323 연동 시스템이 H.323 Endpoint로부터 등록 메시지를 받았을 때 H.323 Endpoint의 등록 정보를 알고 있어야 하므로 수동모드인 환경파일을 선택해서 SIP-H.323 연동 시스템에서 필요에 맞게 구현을 한다.On the other hand, when the H.323 endpoint is registered in the SIP-H.323 interworking system, the SIP-H.323 interworking system selects and processes the environment file in manual mode. When the SIP-H.323 interworking system receives the registration message from the H.323 endpoint, it needs to know the registration information of the H.323 endpoint, so select the environment file in manual mode to implement the implementation in the SIP-H.323 interworking system as needed. do.

SIP-H.323 연동 시스템이 SIP UA를 H.323 게이트키퍼에 등록할 때 자동모드 환경을 사용하면 등록과정은 호 설정을 하기 전에 이루어지는 작업이고 이미 SIP UA에 대한 정보는 SIP-H.323 연동 시스템이 가지고 있기 때문에 그냥 단순히 H.323 게이트키퍼에 등록만 하면 되므로 자동모드를 사용함으로서 크게 관리해줄 필요가 없다.If the SIP-H.323 interworking system uses the automatic mode when registering the SIP UA to the H.323 gatekeeper, the registration process is performed before the call setup and the information on the SIP UA is already connected to the SIP-H.323 interworking. Because the system has it, you just need to register it with the H.323 gatekeeper, so you don't have to manage it by using automatic mode.

또 호 설정이 된 후에도 다른 SIP UA들이 등록 메시지를 보낼 수 있으므로 자동모드를 사용하면 처리가 간단하다.In addition, other SIP UAs can send registration messages even after the call is set up.

H.323 Endpoint가 SIP-H323 연동 시스템에 등록할 때는 H.323 Endpoint의 정보를 가지고 있어야 하기 때문에 수동모드를 선택해서 SIP-H.323 연동 시스템을 적절하게 구현해야 한다.When the H.323 endpoint registers with the SIP-H323 interworking system, it must have the H.323 endpoint information. Therefore, the manual mode must be selected to implement the SIP-H.323 interworking system.

이렇게 별로 중요하지 않은 작업이거나 단순작업은 자동모드 환경파일을 선택해서 처리하면 빠르고 많은 메시지 처리를 할 수 있다.This less important task or simple task can be processed quickly by selecting the automatic mode configuration file and processing a lot of messages.
