FIG. 1 is a structural view of a service platform exchanger to which the present invention is applied.

A service platform exchange 200 is connected between the service terminal 100 and the service server 300. The service platform exchange 200 includes an ATM Local Subsystem (ALS) A0, an ATM Central Subsystem (ACS) A1, a connection control function CC (A2), a service control function SC (Service Control (A3) , Resource control (RC) (A4), access control function (AC) (A5) and distributed processing subsystem ALS (A0) And a module for network matching and a network synchronizing unit for control and related function processing and maintenance. The ALS as a concentrator has a n: m home ratio ratio with the number of links on the user side being n and the number of links on the switch side being m The ACS (A1) does not have a call and connection processing control, unlike the ALS, as a pure interconnector without connection processing light to exchange information between ALSs. The switch network module of the ACS is a self-routing switch, Same switch ACS has a processor for the operation and maintenance of the system as a whole, and it performs maintenance, test, measurement and statistical functions of system resources as well as management of messaging control, operator and various control functions It also has an MMC (Man Machine Communication) interface entity, which is responsible for communication with the MMC.

The communication control function block A2 is the initial connection portion with the network providing point-to-point and point-to-multipoint connection setup. Therefore, if it is dependent on the element of the network, it uses the connection scheme according to the structure of the exchange system which is an element of the network, and uses the network signal technique when it is independent from the network.

The service control function block A3 includes a user entity function for user management, a service session manager function for service management and control, and a service coordinator function for controlling an entity and a service session manager.

The resource control function block A4 manages the resources necessary to provide the service to the user. The access control function block A5 examines the characteristics of the terminal connected to the network, performs a proof check and an authority check function of the user, and performs an initial access control procedure. The service platform functional blocks can provide service routing, network service monitoring, user authentication and verification, terminal compatibility checking, user state management, service state management and electronic secretarial services.

In the present invention, a service platform between a VOD user and a server uses a service platform exchange that provides various services in a more convenient and quick manner to improve accessibility for each service, and receives a command to connect a VOD service from a user , It checks the account and password of this subscriber, directs the server address, and then negotiates whether any of the resources connected to the server are available. If there is an available resource, create a user entity in the connection management state between the client and the server, and then connect the server with the user. When the VOD service release request is issued from the user, the resource is released and the user entity is deleted.

2a to 2c are diagrams illustrating a method of accessing a VOD service in a service platform exchange according to the present invention. In order to accommodate the VOD connection request of the user, it can detect the reception of a signal related to the connection request in a dormant state as an algorithm and provide the corresponding service.

FIG. 2A is a service activation step 1 for setting up a VOD service. A user requests a point-to-point connection to a communication control function block by power on (1). The communication control function block then requests an ID (user unique number) for the requested user (2). The user transmits his ID and waits (3). After receiving the ID, the communication control function block extracts the menu data from the menu data server and transmits the VOD provider menu to the user (4). The user selects a menu displayed on the screen of the terminal and transmits desired VOD provider information (5). (8) and a menu selection (9) in the same procedure after transmitting the program information provided by the VOD to the user (6), receiving the program information selected by the user (7) . After this procedure is performed, the communication control function block transmits the user information to the access control function block to confirm the user.

The access control function block that has received the request checks the type of the requested terminal and checks the ID of the user using the access right checking server (10), and transmits the confirmation result (11). Upon receiving the confirmation result, the communication control function block transmits a service use right confirmation message to the connection control function block (12). In the access control function block, the authority of the user is confirmed and the result is transmitted (13).

The communication control function block confirming the user and the authority of the user transmits the requested information to the service control function block in order to provide the VOD service requested by the user (14). The service control function block requests resource status and allocation required for service provision to the resource removal function block (15). And receives a response from the resource control function block (16). In addition, the service control function block includes a user entity for controlling and managing a service for a user, a service session manager for service control and management, (17) a service coordinator for controlling and managing various processes and resources required for provisioning. After all these control procedures are satisfied, the service control function block transmits the point-to-point connection request to the communication control function block (18), and the communication control function block makes a point-to-point connection to the network's broadband switching system (19). Through the above procedure, the user and the server are sent to the control function block 20 to complete the service setting step.

2b is a step for providing a VOD service. While the VOD service is proceeding between the user and the server, the resource control function block monitors whether the data transmitted between the access points does not violate the transmission quality requested by the user (23) Continuously monitor resource usage to see if it uses bandwidth overruns (24), and also extract statistics for it (25). When the service control function block receives the control signal of the user at the time of providing the service (21), the communication control function block transmits the corresponding menu (22).

In step 3c, the VOD service is released. When the user requests to release the service (26), the communication control function block issues a service release request to the access control function block (27) A session release request is made (28). In response to the request, the function blocks release the internal resources allocated to provide the service, and the service control function block requests resource release to the resource control function block to release the connected external resource (29). Finally, as a procedure for releasing all the connection state, the communication control function block releases the connection device that has been connected between the user and the server (30).

As described above, according to the present invention, a signal connection method between a user and a service platform for connecting a VOD server to an arbitrary user in a service platform exchange, and a method for efficiently providing a connection processing function between a service platform and a server are provided Thus, it is possible to improve the hassle of connection for each service, and it is possible to provide various services more conveniently and quickly.
