6A and 6B are flowcharts illustrating an embodiment of a service setting method according to characteristics of a multimedia device of a terminal according to the present invention.

When the access session is established and the environment for the service is all set, the user selects a desired service from the subscribed services (601). The selected service is delivered to the UA object via the PA object (602, 603), and the UA object requests the creation of the service to the SF object (604).

The SF object creates a USM and SSM object for the selected service (605), and passes the interface reference for the USM object to the PA object and the AS_UAP object via the UA object (607, 608, 609). The AS_UAP object receiving the object reference creates an SS_UAP object for the corresponding service to prepare a terminal environment for the service (609).

In response to the service start from the terminal, the SS_UAP object requests the SFM object to the multimedia resource necessary for the service (610). The multimedia resource is represented by the stream flow terminal point, and the number of input video and audio is limited according to the terminal capability expression information, and allocation and release are performed within this number.

The SFM object allocates SFEP as requested by the service, creates an MDev object capable of controlling each SFEP (611), and transmits the result value to the SS_UAP object (612). The SS_UAP object conveys the allocated SFEP information to the USM and SSM object, and thus a session graph is constructed, and this information is also passed to the CSM object for connection on the communication network (613-616).

The communication session constructs a logical connection graph to graph the shape for the connection in the service (617). The CSM also forwards SFEP information to the TCSM for the node connectivity graph configuration (618). The TCSM receives the SFEP information and allocates a network flow end point (NFEP) corresponding thereto (620). The data stream from the stream flow endpoint is transmitted over the communication network through the network flow endpoint.

After the session graph and the connection graph are configured according to the SFEP information and the NFEP allocation is performed, the CSM transfers the allocated NFEP information to the CC object (621), and the CC object forms a physical connection graph according to the information (622). ).

If another user joins the service later or creates another service, the stream flow endpoint is allocated through the SFM object, and the release procedure is performed when the service is terminated.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

In the present invention as described above, service management, terminal management, subscriber management, and service user management are effectively operated through each object composed of object components in a distributed processing environment. In addition, when user authentication is completed, the service user sets the terminal and the service environment according to the service user information, and the user can easily perform resource management and device control on the multimedia device regardless of which service is used.

In addition, the present invention dynamically allocates and releases a multimedia resource through interworking with a service object component implementing service control logic, and the user can receive a desired service according to the current terminal capability.
