Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a network to which an integrated service providing method using a broadband communication network according to an embodiment of the present invention is applied.

As shown in FIG. 1, the integrated service terminal 100 remotely connects to an access terminal to be serviced via the broadband communication network 70 and simultaneously accesses the vehicle 10 using a function of providing the service terminal. When connecting to the VoIP terminal 30, a telematics service is connected, and a mobile communication service such as 3G is connected, and when connected to a home server 40 in the home, a Web TV, a home appliance control, an IP phone, and a surveillance camera are connected through a home network. The service is available. In addition, in the ubiquitous era, as well as accessing a credit card through RFID, the contents of the biometric device embedded in the human body can be freely used without any limitation of time and place with a single integrated service terminal 100 without a separate monitor or PC.

The integrated service terminal 100 is provided with a selection menu display function that allows a subscriber to access an IP terminal to be connected and select a desired service. At this time, it is connected to the home server 40, the VoIP terminal 30, the DMB terminal, the VoD server 20, and the like remotely by using a remote access program such as an enhanced VnC program. It is possible to provide various functions such as connecting a terminal using a serial port. In the present invention, the home server 40, the VoIP terminal 30, the DMB terminal, the VoD server 20 and the like are referred to as service terminals.

The integrated service terminal 100 according to the present invention is a service method that provides a remote access program and a broadband communication network that provides an encoding / decoding technology, a mobile IP function, and the like, and provides a desired service by the remote access program. Since the result of the service executed in the service terminal is received and output after connecting to the service terminal, even if the available services increase, the price or size of the integrated service terminal is not affected. Regardless of the location of the service, the service provided by the IP terminal in the network to which it is accessible may be used through the integrated service terminal 100 anytime and anywhere.
Hereinafter, an integrated service providing method using a broadband communication network according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG. 2.

The integrated service terminal 100 applies the mobile IP technology through the procedure as shown in FIG.

When the integrated service terminal 100 moves to a new access point (AP), the integrated service terminal 100 requests the care-of-address (CoA) -related information to the access control router (ACR) 110, thereby providing the ACR. CoA related information is notified from (110) (①).

Subsequently, the integrated service terminal 100 transmits CoA related information of the integrated service terminal 100 to a home agent (HA) to request registration, thereby requesting updating of binding related information. By the request, after updating the binding related information in the HA 120, the HA 120 transmits a registration response to the integrated service terminal 100 (2).

Subsequently, the HA 120 encapsulates the packet transmitted from the destination node (CN: Correspond), encapsulates it, tunnels it to the ACR 110, and transmits the encapsulated packet to the ACR 110. The ACR 110 decapsulates the packet. Transmission to the integrated service terminal 100 (③).

Through the above procedure, the integrated service terminal 100 is supported for mobility.

On the other hand, the integrated service terminal supported mobility through the above-described process outputs the integrated service menu (S2), and outputs the service selected by the subscriber of the integrated service menu on the integrated service terminal 100.

In this case, the remote control program included in the integrated service terminal 100 sets the connection target device, which is a service terminal providing the service, as a server, sets the integrated service terminal 100 as a client, and outputs the connection target device. The multimedia data is output to the integrated service terminal 100.

For example, if VoIP is selected on the integrated service menu, the integrated service terminal 100 accesses the VoIP terminal 30 through the broadband communication network 70 (S6), and activates the VoIP terminal 30 (S8). As the VoIP terminal 30 is activated, audio / video data output to the VoIP terminal 30 is also output to the integrated service terminal 100.

When the integrated service terminal 100 inputs the called number to be called on the VoIP screen output through the screen (S12), the called number is transmitted to the VoIP terminal 30 through the broadband communication network 70, the VoIP terminal ( Send the called number through 30) (S16).

When the called terminal corresponding to the called number is called by the broadband communication network, and the called terminal answers the call, an RTP session is connected between the VoIP terminal and the called terminal, thereby enabling a VoIP call between the VoIP terminal and the called terminal (S18).

As described above, in the process of using the VoIP service, the multimedia data output to the VoIP terminal 30 is output to the integrated service terminal 100, the call content input from the integrated service terminal 100 is the VoIP terminal 30 As it is transmitted to the called terminal via the, the integrated service terminal 100 is able to use the VoIP service (S20).

On the other hand, if a service other than VoIP is selected on the integrated service menu, the service terminal corresponding to the selected service is activated similarly to the procedure of S6 to S20 described above to use the service through the service terminal (S22).

In particular, in the present invention, the multimedia data transmitted through the broadband communication network 70 may be encoded by the service terminal (eg, the VoD server 20) to transmit the encoded multimedia data to the integrated service terminal 100. This is because when the decoded multimedia data is transmitted to the integrated service terminal 100 through the broadband communication network 70, the service terminal is output as shown in FIG. 4A, but the integrated service terminal 100 is not compressed. Due to the inability to normally process multimedia data, the normal screen is not output as shown in FIG.

In order to solve this problem, the service terminal (eg, the VoD server 20) encodes the multimedia data and transmits the encoded multimedia data to the integrated service terminal 100. Due to such processing, the integrated service terminal 100 decodes and encodes the encoded multimedia data and outputs a normal screen as shown in FIG.

Referring to FIG. 5, it can be seen that screen (a) of the service terminal and screen (b) of the integrated service terminal 100 output the same data.
On the contrary, if the service terminal is capable of multiprocessing, the compressed multimedia data may be directly transmitted to the integrated service terminal 100 so that the integrated service terminal 100 may decode the multimedia data. In this case, the multimedia data is not reproduced and output through the service terminal.

In an integrated service providing system using a broadband communication network according to an embodiment of the present invention, as shown in FIG. 6, a communication medium may be used as a virtual private network (VPN).

VPNs that securely protect information in the network by allowing access to authenticated users only, are typical of enterprise VPNs that connect corporate branches, branches, and suppliers using MPLS / BGP4 technology. In the future, integrated services will be available by adopting IPSec technology that provides high security for individuals.

As such, when using a VPN instead of a public network, it is possible to effectively block malicious access of other people to information in a private network constructed through an IP network, and provide high security.

In addition, the integrated service providing system according to the embodiment of the present invention provides a quality of service (QoS) because it is localized as shown in FIG. 7.

As shown in FIG. 7, the broadband communication network generates a Label Switched Path (LSP) connecting the LER (Label Edge Router) and the LER according to QoS characteristics by using tunneling and Diffserv technology of MPLS. The bandwidth is set according to the characteristics. Then, when the packet is transmitted from the access network 200, the LER transmits the packet to the LSP supporting the QoS of the packet based on the QoS field value of the packet. As such, QoS is provided.

8 is a diagram illustrating an initial driving procedure of the integrated service terminal 100 according to an embodiment of the present invention.

As shown in FIG. 8, when the integrated service terminal 100 transmits traffic with a HoA address of 0.0.0.0 at power-on (①), the ACR 110 interworks with the AAA server 153 to provide subscribers and services. After authentication (②), the DHCP server 152 allocates the HoA address of the integrated service terminal 100 according to the authenticated subscriber and service information (③).

Thereafter, the ACR 110 binds the HoA address according to the service of the subscriber (④), and the integrated service terminal 100 transmits the traffic by replacing the HoA address with the address assigned from the DHCP server 152 (⑤).

The traffic is transmitted to the HA 120 in an operating state ACT, whereby a registration for the integrated service terminal and tunneling between the HA 120 and the ACR 110 are performed (6).

At this time, the network is classified into CBR: Real time service (VoIP), VBR-rt: Streaming Sevice (Video Streaming), VBR-nrt: Transaction Service (Mobile commerce), and UBR: Best-effort Service (FTP) Qos services such as CBR, VBR-rt, and VBR-nrt will be able to differentiate priority transmissions, and use Dynamic HoA (Home of Address) to prevent resource waste and bypass traffic to remote HA (Home Agent). It can prevent the waste of resources.

According to the present invention as described above, even if one integrated service terminal does not have a module for supporting a specific network or service, services available through a terminal provided on a private network, that is, VoD, home network, GPS , CNS, ITS, LBS and the like can be used.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
