The present invention relates to a method and system for providing a premium service in a portable Internet network. More specifically, the present invention provides a method and system for providing a multimedia premium service that guarantees a certain quality until a session is terminated by separately allocating network resources for service provision before establishing a session for a multimedia service in a portable Internet network. It is about.

As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile subscriber wirelessly, which can provide a service regardless of time and place. In addition, while providing a text message service to complement the voice call service, a wireless Internet service has recently emerged to provide an Internet communication service to a user of a mobile communication terminal through a wireless communication network.

As a result of the development of mobile communication technology, a service provided by a code division multiple access (CDMA) mobile communication system is not only a voice service but also transmits data such as circuit data and packet data. It is developing into a multimedia communication service.

In recent years, IMT-2000 (International Mobile Telecommunication 2000), a third generation mobile communication system that has been established as a standard by ITU-R due to the development of information and communication, has been commercialized. IMT-2000 is CDMA 2000 1X, 3X, EV-DO, Wideband CDMA (WCDMA), etc., and is used in IS-95A and IS-95B networks by using the IS-95C network that has evolved from existing IS-95A and IS-95B networks. It is a service that can provide wireless Internet at a transmission speed of up to 144 Kbps, much faster than the supported data transmission speed of 14.4 Kbps or 56 Kbps. In particular, by using IMT-2000 service, it is possible to provide various multimedia services (AOD, VOD, etc.) at a faster speed as well as improving existing voice and wireless broadcasting service (WBS) service quality.

However, the existing mobile communication system has a limitation in providing high-speed wireless Internet due to the high base station construction cost and high usage rate of the wireless Internet, and the small size of the mobile communication terminal, which limits the available contents. Wireless Local Area Network (WLAN) technology has limitations in providing air services due to problems such as radio wave interference and a narrow coverage area. Accordingly, a portable Internet (PI: Portable Internet or WiBro: Wireless Broadband Internet) system that can use a high-speed wireless Internet service at a low rate while moving has emerged.

The portable internet system uses various types of portable terminals such as laptops, PDAs, and handheld PCs to access various types of information and contents by accessing the Internet in indoor and outdoor stationary environments and in mobile environments at walking speeds and low to medium speeds. It is a service. In addition, it provides mobility of 60 km / h per hour, and has a downlink transmission rate of 24.8 Mbps but an uplink transmission rate of 5.2 Mbps, which is an IP (Internet Protocol) based wireless data system having up-down asymmetric transmission characteristics.

In addition, the portable Internet system uses a frequency band of 2.3 GHz, and draws a time division duplex (TDD) by a duplex method and a multiple access method to effectively use an allocated frequency spectrum. Orthogonal Frequency Division Multiple Access (OFDMA) is used for this purpose.

Meanwhile, in order to provide multimedia services required by service subscribers on a wired or portable Internet with a desired quality of service, a quality of service (QoS) according to each user must be provided. IP-based internet network does not guarantee high quality because it provides Best Effort Service. As a result, integrated services proposed by the Internet Engineering Task Force (IETF) have been developed as a way to guarantee QoS.

Here, QoS refers to a service level required for a specific application program. In general, a method for guaranteeing QoS is based on a resource reservation parameter (RSVP) for allocating network resources according to QoS requirements using a resource reservation protocol (RSVP). Therefore, priority parameters that control network traffic by managing bandwidth are used.

1 is a view for explaining the operation of RSVP for QoS guarantee in a conventional RSVP-based network.

A typical system for providing QoS includes a transmitter 110, an RSVP network 120, and a receiver 130. The transmitter 110 serves to provide a multimedia service. The RSVP network 120 is a network that delivers a message using RSVP, and is composed of network equipment such as a plurality of routers for delivering the message. The receiver 130 is a client requesting and receiving a multimedia service.

The transmitter 110 transmits a path message specifying a traffic characteristic of the multimedia service to the receiver 130 through the RSVP network 120 to provide QoS, and transmits its own traffic characteristic to the receiver 130. Inform. The path at this time is determined by an IP (Internet Protocol) unicast or a multicast routing protocol. The receiver 130 receiving the path message analyzes the traffic characteristics of the transmitter 110 to determine its desired bandwidth and transmits a reservation message to the transmitter 110. The reservation message is delivered in the opposite direction along the route through which the route message was delivered. Routers in the middle of the RSVP network 120 receiving the reservation message may accept or reject the reservation message according to the service requirements recorded in the reservation message in the process of delivering the reservation message. If the reservation request is rejected, the router rejecting the request transmits an error message to the receiver 130 and the signaling process ends. If the request is accepted, the link bandwidth and buffer space for the service are allocated and the relevant service status information is installed in the router.

As described with reference to FIG. 1, a scheme of providing a typical QoS includes an access for transmitting a parameter (resource reservation parameter, priority parameter) for guaranteeing QoS to the router which is a network device of the RSVP network 120 in the receiver 130. I'm taking the way. However, in this conventional method, since the receiving unit 130, which is a client, needs to directly participate in a complicated signal processing task for guaranteeing QoS, the load that the receiving unit 130 must bear increases, and software necessary for the signal processing task is embedded. As a result, the requirements of the receiver 130 such as a memory, a central processing unit, and a peripheral device increase.

On the other hand, as described above, recently, multimedia services using a portable Internet system, which accesses the Internet in a mobile environment using a portable terminal and provides various information and contents, have been highlighted. In such a recent situation, it is obvious that a high quality service that guarantees QoS to a mobile communication subscriber who wants to receive a multimedia service using a portable Internet system will be positioned as an essential service. However, if QoS is guaranteed in the same manner as in the related art, the load burden on the portable terminal increases, and the required specification also increases. This may act as a factor that hinders the activation of the use of the portable Internet service, and may be a burden on the service subscribers using the portable Internet service.

In order to solve this problem, the present invention provides a multimedia premium service that provides a multimedia service with a certain quality by constructing a separate system for guaranteeing QoS in a portable Internet system and allowing the system to perform a task for guaranteeing QoS. Its purpose is to provide a method and system for providing the same.

In order to achieve the above object, the present invention provides a personal subscriber station (PSS), a portable Internet network (HPi: High Speed Portable Internet or WiBro: Wide Broadband Internet), a premium providing server, and a premium application server.

A system for providing a premium service for transmitting a premium application that provides a premium service for transmitting content by guaranteeing QoS by generating content and requesting resource allocation by generating QoS information according to a request of a personal subscriber station. server; A premium provision server which generates a QoS parameter using the QoS information received from the premium application server and requests a resource allocation operation on a path for transmitting data from the premium application server to the personal subscriber station; Includes a radio access station (RAS: RAS), an access control router (ACR), and a number of network devices in an IP network (Internet Protocol Network). However, the mobile Internet is connected to the personal subscriber station, premium provision server, and premium application server to perform resource allocation to ensure QoS according to the request of the premium provider server, and to relay data transmitted and received between the premium application server and the personal subscriber station. QoS parameters include a resource reservation parameter and a control parameter for using a wired resource on a wired path for transmitting and receiving data between a personal subscriber station and a premium application server and a line or network equipment on the wired path, including a network.
