Abstract

Provided is a system and method of providing a seamless on-demand service using a Deep Packet Inspection (DPI) function. A system for providing an on-demand service may include: a switch to recognize a signature of media, and to convert a resolution of media based on information associated with a resolution of media included in the recognized signature, a terminal resolution of a terminal held by a user, and a user requirement; an authentication management server to perform a terminal authentication or a user authentication; and a policy control server to set a path based on a terminal function, a media characteristic, and the user requirement.

Claims

1. A system for providing an on-demand service, comprising:

a switch to recognize a signature of media, and to convert a resolution of media based on information associated with a resolution of media included in the recognized signature, a terminal resolution of a terminal held by a user, and a user requirement;

an authentication management server to perform a terminal authentication or a user authentication; and

a policy control server to set a path based on a terminal function, a media characteristic, and the user requirement.

2. The system of claim 1, wherein the switch has a capability of processing a payload of an Internet Protocol (IP) packet, and includes a Deep Packet Inspect (DPI) processor to analyze the signature of media and convert the resolution of media according to an application service.

3. The system of claim 1, wherein the switch authenticates the terminal or the user, detects a signature of media data, measures a transmission amount of the media data, and converts the resolution of media to be suitable for a receiving terminal.

4. The system of claim 1, wherein the authentication management server includes a terminal authentication information list and a user authentication information list, and performs an authentication management using the terminal authentication information list and the user authentication information list.

5. The system of claim 1, further comprising:

a charge management server to manage charge information,

wherein the switch transmits user information and the charge information to the charge management server after terminating an application service.

6. The system of claim 5, wherein the policy control server stores DPI information, transfers the stored DPI information to the switch, sets an application media service path based on a terminal function using media passing through the switch, a media characteristic, and the user requirement, transfers information associated with the set application media service path to the switch, and transmits, to the charge management server, charge information associated with a media class and a path set.

7. A method of providing an on-demand service, comprising:

processing, by a switch, an authentication using a terminal authentication information list when a terminal authentication request is received;

processing, by the switch, an authentication with respect to an existing service user using a user authentication information list;

recognizing, by the switch, a signature in a payload of media data transmitted using a DPI processor to verify resolution information of at least two terminals using a corresponding service;

comparing, by the switch, the verified resolution information to convert a resolution of media to a lowest resolution; and

providing, by the switch, a seamless on-demand service using path information transferred from a policy control server.

8. The method of claim 7, further comprising:

measurement, by the switch, a media data transmission amount; and

cutting off, by the switch, disallowed media by recognizing the signature using the DPI processor, or by recognizing a pattern of an image content.

9. The method of claim 7, further comprising:

informing the authentication management server that the authentication fails when a terminal authentication or a user authentication fails.

10. The method of claim 7, further comprising:

storing, by the policy control server, DPI information to transfer the DPI information to the switch;

setting, by the policy control server, an application media service path based on a terminal function using media passing through the switch, a media characteristic, and a user requirement;

transferring, by the policy control server, the set application media service path to the switch; and

transmitting, by the policy control server, a class of application media and charge information associated with a path set to the charge management server.

11. The method of claim 8, further comprising:

transmitting, by the switch, user information and the measured media data transmission amount to the charge management server after terminating a service.
