The biggest problem among them is that packet data can be provided with various services such as wireless Internet, video telephony, Video On Demand (VOD), and Java 2 Micro Edition (J2ME), which is the current wireless protocol of 1xEV-DO, IS-856. Since there is no way to distinguish and process various types of services, there is a significant problem with real packet data services.

Therefore, in the current technical field, a scheme for providing various services by dividing each service type in 1xEV-DO network is required.

SUMMARY OF THE INVENTION The present invention has been proposed to meet the above requirements, and provides a multimedia service method and a method for realizing the multimedia service by classifying a packet data service in a wireless communication network such as 1xEV-DO.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration of a 1xEV-DO wireless communication network to which the present invention is applied.

First, 1xEV-DO will be described in more detail to aid in understanding the present invention.

1xEV-DO is a high-speed packet data transmission protocol defined by CDMA2000, which is a synchronous IMT-2000. The omni-directional transmission rate from the base station to the terminal can transmit up to 2.4576Mbps. The forward direction is Time Division (TD) -Code Division Multiple Access (CDMA). Each piece of information is transmitted in time division on a CDMA basis, and the reverse direction is also transmitted in CDMA.

The omni-directional transmission method is a method of guaranteeing high-speed transmission by transmitting from the base station at maximum power.

The reverse transmission method is a transmission method that is transmitted at a maximum of 153.6kbps in consideration of the terminal side.

As described above, the 1xEV-DO protocol is a packet data-only transmission, unlike voice, which should be guaranteed in real time, so that the subscriber and transmission rate accommodated in the wireless section are much better than the existing IS-2000. However, the 1xEV-DO protocol basically focuses on internet access using an external terminal such as a PC, and provides various services such as video on demand (VOD), wireless application protocol (WAP), and video telephony. There is no parameter to provide practical service.

Therefore, in order to provide a service using 1xEV-DO, as shown in FIG. 1, the base station 12 should have a structure in which the wireless IP network 14 is directly connected. The base station 12 uses the IP network 14 without using the existing voice-oriented circuit data network. The base station 12 is connected to a Packet Data Serving Node (PDSN) 13, and uses IS-878, which is a separate Interoperability Operation Specification (IOS), for 1xEV-DO.

The terminal 11 transmits a desired service to the base station 12, and the base station 12 connects to the PDSN 13, which is a system node connected to the IP network 14. The PDSN 13 assigns routes to various application service servers. 1xEV-DO, a wireless protocol, does not have a definition for each service type, which causes problems with commercial services. Accordingly, the present invention intends to provide various multimedia services by newly defining the 1xEV-DO protocol, which is a high-speed packet data transmission method, so that service types can be distinguished.

2 is a structural diagram of a 1xEV-DO session protocol to which the present invention is applied.

As shown in FIG. 2, unlike the conventional IS-2000, the protocol structure of 1xEV-DO is mainly composed of packet data transmission. This is defined in international standard as IS-856. In the present invention, the session configuration protocol of the session layer is improved, and a part for distinguishing a service type is defined and added.

The session configuration protocol uses a ConfigurationRequest message and a ConfigurationResponse message. In IS-856, only the basic matters of these messages are defined. In the present invention, the service types are distinguished by supplementing them.

3A to 3D are structural diagrams illustrating an embodiment of application service classification based on a ValueID of a 1xEV-DO session protocol according to the present invention.

The present invention is achieved by newly defining an attribute identifier (AttributeID) (see FIG. 3C) which is a detailed structure of an attribute record (AttributeRecord) (see FIG. 3B) of a configuration message (see FIG. 3A).

The service for each layer according to the attribute identifier value is shown in FIG. 3C, and each parameter value is as follows.

Referring to FIG. 3C, the attribute identifier "0x00-0x05" is a reserved space, the attribute identifier "0x06" is a security layer application unit, and "0x07" is a session layer application. And the attribute identifier "0x10" is a service type identifier. And, the attribute identifiers "0xA0 to OxFF" represent a manufacturer and a carrier application part.

The detailed value identifier (ValueID) of the attribute identifier "0x10" is defined as shown in FIG. 3D.

Referring to FIG. 3D, the value identifiers "0x00 to 0x0F" are reserved spaces, and the value identifier "0x10" is a delay layer model. The value identifier "0x11" is a network layer model. In addition, the value identifier "0x12" is a Video On Demand (VOD) service, the value identifier "0x13" is an Audio On Demand (AOD) service, the value identifier "0x14" is a Wireless Internet service, The value identifier "0x15" is Mobile Multimedia Service (MMS), the value identifier "0x16" is High Speed Broadcasting Service (HSBS), the value identifier "0x17" is Location Service (LCS), And the value identifier " 0x18 " represents a video conference, respectively.

As described above, the base station and the terminal may be used for path allocation of the PDSN by using factors for identifying each application service for a new session.

In addition, on the terminal side, these values can be used to set the protocol according to the desired application service.

4 is a detailed flowchart illustrating a signal processing procedure in a system for a multimedia service through application service identification according to the present invention.

As shown in FIG. 4, the process of call processing from the base station to the PDSN using the service type classification factors proposed by the present invention is as follows.

The base station determines the reasonableness by looking at the service type classification factor received from the terminal. If it is a predefined value, this value is transmitted to the PDSN (401). Thereafter, the PDSN notifies the base station that it can process (402), and allocates a path to the application service server that wants the service (403).

5 is a detailed flowchart illustrating a signal processing procedure in a terminal for a multimedia service through an application service according to the present invention.

As shown in FIG. 5, when a subscriber selects a 1xEV-DO application service using a terminal menu and a personal computer (501), the terminal may provide a corresponding service desired by the user. In operation 502, if a corresponding service is not provided, a corresponding message is displayed in a general standby state (503).

On the other hand, if the corresponding service can be provided, the terminal constructs a lxEV-DO radio section message in the manner proposed by the present invention (504), and finally transmits it to the base station (505).

Thereafter, when the base station returns a response to the processing possible (506) and proceeds to the next processing (508 to 511), if there is no response, the terminal is in a standby state and displays the reason on the terminal screen (507). That is, when the terminal receives the response, the protocol for the application service is internally set (508), and when the setting is completed, the application service is provided to the application service server and end-to-end (509). ). When the provision of the application service is terminated (510), the terminal is in a standby state again (511).

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. Will be evident to those who have knowledge of

As described above, the present invention provides a method in which IS-856, which is a wireless protocol of 1xEV-DO, can distinguish various service types, thereby enabling wireless Internet, video telephony, and VOD (Video On) at high capacity and speed of 1xEV-DO. It is able to provide various services such as Demand) and Java 2 Micro Edition (J2ME).
