In the next-generation network system, the present invention provides various service capabilities, and at the same time, combines individual service capabilities to provide new service capabilities, thereby reducing network resource waste while providing more diverse service capabilities. To be provided.

Figure 1 shows an embodiment of a next-generation network service system having a service capability combination function according to the present invention, where all node devices are physically connected to an IP (packet) network.

As shown in FIG. 1, the next-generation network service system according to the present invention includes a plurality of soft switches 3 to 5 and a plurality of soft switches 3 to 5 to perform an exchange function in each local network area 2. 5) a plurality of application / media servers 6-8, each providing a unique service capability to the user terminal through each, and a plurality of soft switches 3-5, respectively, connected between the local network area 2; A plurality of service connection agents (9-11) for connecting, and a service capability combination control device (12) for combining and interworking the service capabilities of each area through the plurality of service connection agents (9-11).

In the illustrated next generation network service system, there is a unique network area 1 provided by a network provider, and the unique network area 1 includes each local network area where different services are provided by a plurality of service providers. 2) is made, including. In FIG. 1, for convenience, it is assumed that there are three local network areas A, B, and C provided with different service capabilities A, B, and C, respectively, by the respective application / media servers 6 to 8. The network areas 1 and 2 may be linked to other network areas in an open structure.

The soft switches 3, 4, and 5 respectively provided in the local network area 2 are network nodes that handle IP (Internet Protocol) based call control when providing various service capabilities based on multimedia basic call control capabilities. .

In addition, there are application / media servers 6 to 8 that provide unique service capabilities in each local network area 2, thereby providing each multimedia service to the user.

For example, local network area A provides a service capability called video conference through an application / media server 6, and in network area B, a video on demand (VOD) through an application / media server 7 is provided. It can provide a service capability.

In addition, in the system of the present invention, in order to combine the two service capabilities provided in each of the local network areas 2, a service connection air agent enabling service connection control for each network area A, B, C ( 9 ~ 11) to the soft switch (3 ~ 5) of each network area.

When the service capability is treated as a session from the user's point of view, the connection of the session means that the service connection agent 9-11 uses the network configuration resource to associate with the service capability connection. In addition, the system according to the present invention implements such a service connection agent (9-11) in a distributed computer operating system, it is possible to link the connection control for each service capability between each network area (2). The service connection agents 9 to 11 may be physically configured as independent systems, or may be configured to operate with separate computing in the application / media server device 25.

The service capability combination control apparatus 12 combines different service capabilities provided for each network area through the service connection air agents 9 to 11. The service capability combination control apparatus 12 is mapped to a session for each service capability unit to combine different service capabilities.

2 illustrates a hierarchical structure of the next-generation network shown in FIG.

2, in the next-generation network hierarchy, the lowest user terminal layer L4 corresponds to a group of user terminals 21 using a service, for example, a telephone, a PC, a PDA terminal, and the like.

A next-generation network 22 including a soft switch, an access gateway, a backbone IP network, and the like is provided at a network connection layer L3 that enables data communication between the user terminals 21.

The next generation network of the present invention further includes a service-based connection layer L2 for connecting different services provided through the network connection layer L3, and each of the service-based connection layer L2 has a predetermined capability. Application / media server devices (6 to 8) for providing a, and the service connection agent (9 to 11) for connecting the application / media server devices (6 to 8).

In addition, a service combination / control layer (L1) for combining a plurality of application / media server devices (6 to 8) through the service connection air agent (9 to 11) to combine service capabilities is provided with the service capability combination control device (12). Is implemented by

Here, the upper service capability is controlled by the session, the session is mapped to the service-based connection layer (L2), and then to the next-generation physical network 22, end-to-end, multicasting, etc. The mapping is done in the manner of. An open session based protocol 23 is introduced to control next generation network connection resources for this mapping. The protocol 23 performs primitive processing to enable real-time connection information.

The connection between the service capability combination control layer L1 and the service-based connection layer L2 is performed by applying the object-based distributed computing platform 24 to a distributed computing environment. The platform 24 serves to ensure that each object of the service capability unit according to the service capability session model matches the computing model mapped with the connection resources of the next generation network. The object-based distributed computing platform 24 serves to connect the operation relationship between the service capability combination control device 12 and the plurality of service connection agents 9 to 11 in a mutually flexible server and client manner, and the service When the operation element objects in the capability combination control apparatus 12 perform the service capability combination procedure to identify the necessary objects in the process of interacting with each object of the service connection agent 28, and register the request.

Here, since the service connection agents 9 to 11 are physically distributed and installed in the application / media servers 6 to 7 that provide multimedia services of the next-generation network, their configuration information is assigned to the service capability combination control device 12. ), And defines only formalized object interface and is used to control service capability combination.

In addition, the service capability combination control apparatus 12 performs a center function for performing group communication between a plurality of service connection agents 9 to 11.

In the present invention, as shown in FIG. 2, a relationship structure diagram for reducing the dependence between upper and lower layers while unifying the connection environment as shown in FIG. 1 is presented as shown in FIG. 2. Apply without modification.

Fig. 3 is a detailed block diagram showing the internal structure of the service capability combination control apparatus 12, and shows an example of the operation of combining the service capabilities in the user terminals 21a and 21b.

Here, the interoperable operation control between the operation objects is an open object type connection method, and the service capability media transmission to the user terminal is indicated by the stream input / output method. The service capability media transmission path 212 between the user terminals 21a and 21b and the service capability combination control apparatus 12 is a bidirectional transmission path of this stream, which is realized in the form of packetized data of an IP-based network.

Referring to FIG. 3, the user terminals 21a and 21b are provided with an operation object called a terminal computing module 211 that performs an operation according to the control of the service capability combination control apparatus 12. Each time it is formed, it is produced and destroyed.

In addition, the service capability combination control apparatus 12 connects the session management module 33 for each service capability unit corresponding to two service capabilities requested by a user, and controls a stream input and output of the corresponding user terminals 21a and 22b. The capability management unit 31, the session management module 32 for each service capability unit for coordinating between the user terminal session management module 33, and the service capability session for each user to generate configuration characteristic information of the service capability used by the user. It consists of a user terminal session management module 33 to maintain the mapping information for each user and service capability.

In the above, the service capability unit session management module 32 determines which node of the next generation network (1, 2) the service capability session connected to provide the service capability to command the corresponding service connection agent (9-11). Get off.

For example, when the user terminal 21a requests a video conference from another user terminal 21b, as shown in FIG. 3, a service capability between the terminal computing modules 211 of the user terminals 21a and 21b is shown. The unit A bridge 311 is generated and is directly connected to the service capability unit A bridge 311 through the transmission path 212. That is, this connection structure is a video conference between the two user terminals (21a, 21b).

As such, in order for one user to suggest the service capability of another service capability provider and to have the content of this service capability as a meeting subject, a process of forming a new stream bridge by the service capability combination is required. Control for this is performed by the service capability combination control unit 31. The control is achieved in relation to the moving object.

The control unit 31 generates bridges 311 and 312 for each service capability. The bridges 311 and 312 determine the binding method according to the stream interface of the stream controllers 313 and 314 and the service capability unit bridge combination request. That is, the cross binding 315 has a form of service capability combination according to the number of cases where the cross binding 315 is bound to the service capability unit bridges 311 and 312 and the stream controllers 313 and 314.

If one service capability unit B is Video On Demand (VOD), the stream interfaces of the stream controllers 313 and 314 of the service capability unit A and the service capability unit B are connected in parallel. In this case, when the operation of the combined service capability is viewed from the user's point of view, the form creates a combined service capability effect of 'two users are facing each other and having a video conversation at the same time.'

The operation of the service capability combination control device 12 is performed in parallel with the left and right stream connection and binding around the cross binding 315, and the shape of the service capability varies according to the organizer of the service capability. Furthermore, the combination of three or more service capabilities depends on the user's terminal's stream interface access capability and application acceptance, and can be achieved with the concept of extending it.

The operation object in the control unit 31 operates while being present in the form of an instance while passing through the service capability generation / destruction process. The real time capability of cross binding can be solved by improving the combination controller binding 315 portion in a real time softswitched manner.

4 shows an operation flow of the service capability combination control apparatus 12 configured as shown in FIG.

Here, the user terminal 21a and the other user terminal 21b shown in FIG. 3 are divided into user 1 and user 2, respectively, in a state in which two users 1 and 2 use one service capability A and B, respectively. In this case, it is assumed that the requirement of service capability combination is between two users. For example, the service capability A may be a video conference service and the service capability B may be a VOD service.

Referring to FIG. 4, in a state in which users 1 and 2 are in use of service capability A interoperating with each other (S100 and S101), when two users request to combine different service capability B to service capability A under mutual interaction (S102). In step S103, the service capability combination control apparatus 12 checks the user session setting information for the service capability B and the configuration information of the session for the existing service capability A (S104). That is, with respect to the service capability A that is operating, the session feature of the existing service capability A is extracted from the user's state set in this service capability and the configuration information of the service capability session. It is to collect the initial information to be combined.

Then, it is checked whether a session exists for the service capabilities A and B to be combined (s105), and a service session is generated for the service capability where the session does not exist (s107). In the case of the above embodiment, since the service capability A has a session established and is currently in use, only the session for the newly requested service capability B may be further set.

When all the service sessions for the service capabilities A and B to be combined as described above are generated, stream bridges 311 and 312, which are the basic means for connecting the combinations for the service capabilities A and B, are generated for each of the service capabilities A and B. s106).

The stream bridges 311 and 312 generated as described above are objects to be controlled by the combination controller 12, and initialize the operation of the service capabilities A and B and configure the service capabilities for the controller 12 to operate. Identify the information (s108).

The identified configuration information is classified according to the method and characteristic of performing service capability elementization and objectization so as to be combined for each element of multimedia service capability, and is configured in advance so that the combination controller 12 connects / binds the bridges with each other. I know what to do.

The combination controller 12 operates by determining the subject of the service capability combination according to the user based on the configuration information identified as described above.

In the case shown in FIG. 4, as an example, two users perform a combination of service capabilities A and B on a limited basis, and users 1 and 2 combine service capabilities A and B so that both users accept the combined service capability. In the case (s109), the stream bridges 311 and 312 for both service capabilities are bound to the stream connection object on the user side, that is, the stream controllers 313 and 314 (s114). User 1 accepts the combined service capability and uses the service capability A and B at the same time, and user 2 accepts the existing service capability A only (s110), or Conversely, user 1 accepts the service capability A only and user 2 service capability. If both A and B are accommodated (s111), only the user who requests the combination binds the corresponding stream bridge 311 or 312 to the stream controller 313 or 314 (s115). Lastly, in the case of a combination of two users alternately using the service capability with respect to the service capability A and B (s112 and s113), the stream bridges 311 and 312 of the service capability A and B are supplied to the stream controllers 313 and 314. Cross-binding (s116).

In the above, the role of the stream controllers 313 and 314 is to perform connection adjustment according to the preference of the user's subject and the service capability combination of the user, which repeats the process of creation, binding mechanism according to the type, and destruction. If there is more than one user, multiple user stream instances occur and take the form of switching. In the case where the service capability is three or more, the stream bridge is similarly generated in an instance manner and is subject to the handling of the stream controller.

When the binding process is performed as described above and the state of the combination service capability is in the state, it is checked in real time whether there is a request for extinction of the combination by the user giving the initiative (s117), and by the check, the service capability combination is destroyed from the user If there is a request, the previously connected binding is switched to the previous state (s119). On the contrary, if there is no request for extinction for the service capability combination, the service capability combination is continuously maintained (s118).

The above processing of steps s100 to s118 is repeatedly performed.

If the user wants to combine another service capability with the two service capabilities combined, consider the already combined service capability as one other service capability unit and perform the above procedure.

In the above, the configuration information is limited to two users and two service capabilities, but in most cases, the service capability combination control apparatus according to the present invention operates as a multi-control in which a plurality of users and a plurality of service capabilities are combined. At this time, the operation of the stream controllers is to maintain the parallel processing scheme to minimize the time required for the combination of service capabilities.

As described above, the present invention can provide a new service capability in combination with the service capability of other service capability providers while at the same time developing a unique service capability for each next generation network and providing the user with a combination of mutual unit service capabilities. By doing so, the user can be provided with a high quality of service while eliminating redundant development of service capabilities.
