In the service platform exchange 200, the service terminal 100 and the service server 300 are connected. The service platform exchange 200 includes an ALS (ATM Local Subsystem) 210, an ACS (ATM Central Subsystem) 220 and a service platform 290. The service platform 290 includes a communication control function block CC A communication control block 230, a service control block 240, a resource control block 250, an access control block 260, A distributed processing system 270, and an application block 280.

The ALS 210 includes a single-stage self-routing switch module, a module for subscriber matching of a controller for processing and maintenance of user related functions, and a network synchronization unit.

As an aggregation device, ALS has a population ratio of n: m, where n is the number of links on the user side and m is the number of links on the switch side.

The ACS 220 is a pure interconnector that does not have a connection processing process for exchanging information between ALSs. Unlike the ALS, it does not have a call and connection processing controller.

The ALS switch network module is a self-routing switch that can use the same switch elements as ALS. ACS has a processor for the operation and maintenance of the entire system to manage system resources, test, measure, statistical functions as well as data storage device control, operator and various input / output problem functions. It also has an MMC (Man Machine Communication) interface entity, which is responsible for communication with the MMC.

A Communication Control Function (hereinafter referred to as CC) 230 is the initial connection with the network providing point-to-point and point-to-multipoint connection setup. Therefore, in case of dependency as an element of the network, the connection method according to the switching system structure, which is an element of the network, is used, and when the structure is independent from the network, the network signaling method is used.

A service control function block (hereinafter, referred to as SC) 240 includes a user entity function for user management by service, a service session management for service management and control, a service coordinator for controlling a user entity and a service session manager Function.

A resource control function block (RC) 250 manages resources required to provide a service to a user.

The access control function block (AC) 260 examines the characteristics of a terminal connected to the network, performs authentication verification and authorization of the user, and performs user management using a user agent function.

The service platform functional blocks may provide service routing, network service monitoring, user authentication and authorization checking, terminal compatibility checking, user state management, service state management and electronic secretarial services.

FIG. 2 (a) through FIG. 2 (c) are processing flowcharts for accepting a connection request of a video conference by a user in a service flat to which the present invention is applied, when the signal related to the connection request is detected in the idle state The service can be provided.

2 (a) and 2 (2) are flowcharts showing a service starting process for setting up a video conference service. The user requests a point-to-point connection to the CC by turning on the power (1). Then, the CC requests the terminal check and the user agent creation (2), AC checks the terminal and creates the user agent (3) and notifies the CC to create the user agent (4). The CC extracts the menu data from the menu data server and transmits the service menu to the user (5). The user selects the menu displayed on the screen of the terminal and transmits the desired service information of the conference to the CC (6).

The CC sends the program information provided by the video conference service to the user (7), the user transmits the video conference connection request information to the CC (8), and the CC transmits the receiver connection request information according to the user's request AC (9).

The SC requests the user entity creation of the video conference (10). The SC creates a videoconference user entity (11), and requests the resource status and allocation necessary for service provision to the RC (12). A response to this is received from the RC (13).

In addition, the SC includes a user entity for controlling and managing a service for a user, a service session manager for service control and management to control requested services in order to generate a plurality of processors for controlling a requested service, And a service coordinator for controlling and managing processes and resources (14).

After all these control procedures are satisfied, the SC sends a point-to-point connection request to the CC (15), the CC requests the network and the broadband switching system for point-to-point connection (16) (17).

The CC that established the connection between the users through the above procedure sends the charging start notification to the SC (18), and the SC ends the service setting phase (19) by requesting the high-priority and statistical start notification from the RC.

2 (b) is a flowchart illustrating a service providing process for providing a video conference service.

While the video conference service is proceeding between the users, the RC monitors whether the data transmitted between the access points is in violation of the transmission quality requested by the user (20), continuously monitors the resource use for whether the requested bandwidth is used or not 21) and the statistics (22) are also extracted. When the CC receives the control signal of the user at the time of providing the service (20), the CC transmits the corresponding menu (21).

2 (c) is a flowchart showing a service lifting process of the video conference.

If the user requests to release the video conference service according to the control signal 22 and the menu 23, the CC issues a service cancellation request 25 to the AC, and the AC calls the video conference user entity cancellation request 26).

The function blocks that have received the request release the internal resources allocated to provide the service, the SC issues a resource release request to the RC to release the connected external resource, and the RC releases the resource release, charging, and control After (28), the RC informs the SC of the resource release (29).

The SC deletes the service session of the video conference (30) and sends the disconnect notice to the communication control function block (3). The CC sends a receiver release notification to the receiver side (32) and then requests a point-to-point connection release (33) to the broadband system of the network.

As described above, the present invention provides an efficient access method for providing a video conferencing service in a service platform exchange in a network, thereby perfectly serving as an application service broker in the network, so that a user can easily use video conferencing.
