Dynamic Creation and Lifecycle Management of Video Conferencing Service Objects in Open Networks

摘要

The present invention introduces a session concept of a video conferencing service applicable to various types of multimedia services in an open communication network based on a connection connection between a client and a server, thereby creating a service, that is, a service session between multiple service users and a video conferencing service provider system. It relates to methods and procedures for creating objects, shaping objects, and managing their life-cycles. This client and server system uses a broadband communication network (B-ISDN) as a transport network, and establishes a distributed processing environment in each system, regardless of the number of users or conference groups requiring video conferencing service, and an object that conducts a conference. Perform services regardless of their location. According to the present invention, when a service session is created, which is a service call connection between service users who want to use a video conferencing service, a method of separating a service user's connection shape management and a service control performed based on the connection shape, and a service user. We devised two methods to separate the specific service shape and control part and the service shape and control part which are applied to all users. Therefore, the present invention is portable and easy to maintain, which can be commonly applied to various types of multimedia services, and a method of constructing and creating reusable service session objects, session management of conference groups, characteristics of services, and roles of service users. The object can be shaped according to this, and the life cycle of the object can be efficiently managed until the end of the service.
