The present invention relates to a method and system for determining a handover type according to a service characteristic provided to a personal subscriber station in a portable internet environment. More specifically, a feature determination server for determining service characteristics is installed in a portable Internet system, and when a service call signal is transmitted from a personal subscriber station, the service characteristic is determined to determine a handover type to provide various services. A system and method for providing a handover type are provided.

As information and communication technology has advanced rapidly, various wireless communication services using a wireless network 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. On the other hand, in recent years, a wireless Internet service for providing an Internet service to a user of a personal subscriber station through a wireless communication network has emerged. The current wireless Internet service uses Code Division Multiple Access (CDMA) 2000 1X, Evolution Data Optimized (EV-DO), Wideband CDMA (WCDMA), or other IS-95A and IS-95B networks. The 95C network provides wireless Internet with data rates up to 144 Kbps, much faster than 14.4 Kbps or 56 Kbps.

Due to the development of mobile communication technology, the services provided by the Code Division Multiple Access (CDMA) mobile communication system are not only voice services but also multimedia for transmitting data such as circuit data or packet data. It is developing into a communication service.

In addition, IMT-2000 (International Mobile Telecommunication 2000) (e.g., CDMA 2000 1X, 3X, EV-DO, WCDMA (WideBand CDMA)), a third generation mobile communication system that has been established as a standard by ITU-R due to the development of information and communication. Etc.) are commercially available. IMT-2000 is a CDMA 2000 1X, 3X, EV-DO, WCDMA (WideBand CDMA), etc., which is used in IS-95A and IS-95B networks by using the IS-95C network that has evolved from the 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 supportable data transfer rate 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 WAP service quality.

Currently, the wireless Internet technology used worldwide includes a third generation cellular system based on the aforementioned mobile phone network and a wireless local area network (WLAN) system based on IP-based packet transmission. .

Existing cellular systems support high mobility and handoff, guarantee data rates required for voice calls, and additionally support packet data services. However, the existing cellular system has a high base station construction cost and high wireless Internet usage fee, and a small screen size of the personal subscriber station restricts the available content and guarantees sufficient transmission speed for packet data service. There is a limit to this.

On the other hand, WLAN guarantees superior data transmission rate compared to cellular systems, but there is a problem in mobility due to radio interference and limitation in provision of public service due to problems such as narrow coverage.

As a result, a mobile Internet (WiBro: Wireless Broadband or PI: Portable Internet) service system that supports cellular mobility and handoff, and provides high-speed wireless Internet service at a low rate, has a transmission speed comparable to that of a WLAN.

The portable Internet service, referred to as the 3.5 generation, uses various types of portable personal subscriber terminals such as laptops, PDAs, and handheld PCs to access the Internet in indoor and outdoor stationary environments and mobile environments at walking speeds and low to medium speeds. It is a service using information and content. In addition, the portable Internet system for providing such a mobile Internet service provides a mobility of 60 km / h per hour and a downlink transmission speed of 30 Mbps, and downlink transmission of 50 Mbps when a multiple input multiple output (MIMO) system is applied. It is an IP-based wireless data system that can provide speed.

In addition, the portable Internet system uses the 2.3 GHz frequency band, and in order to effectively use the allocated frequency spectrum, a time division duplex (TDD) is used as a duplex method, and a multiple access method is used as a multiple access method. Orthogonal Frequency Division Multiple Access (OFDMA) is used. In this case, OFDMA is a multiple access scheme similar to TDMA in which all subcarriers spread over the entire bandwidth are allocated to one user for a predetermined time and to another user for the next predetermined time. In addition, the portable Internet system employs technologies such as Adaptive Modulation Coding (AMC), Multi Input Multi Output (MIMO), and Smart Antenna for efficient operation of radio resources.

In order to receive a service from the portable Internet system, the subscriber accesses the portable Internet system and calls a service desired by the subscriber. The subscriber who is connected to the portable Internet system moves while receiving the service, and when the subscriber moves, the portable internet system provides a handover between the personal subscriber station and the portable internet system.

Handover is the quality of service (QoS) of a service connection provided to a personal subscriber station in a mobile Internet system and the radio link to a new base station so that the connection can be maintained continuously when the personal subscriber station moves from a serving base station to another base station. It is a function to switch. Currently supported handovers include hard handovers that disconnect existing lines first and then connect to new base stations, soft handovers that support reliable handovers using two or more base stations during handovers, and faster handsets. There is a FBSS type handover to support the over.

However, when a service provided to a user by various content providing companies is provided to a user using a mobile Internet system, the mobile communication service provider provides a single handover method determined by policy without considering the characteristics of various services. Handover not considered has a problem of reducing the efficiency of the mobile Internet service network resources.

In order to solve this problem, the present invention provides a variety of services by determining a handover type by determining a service characteristic when a service call signal is transmitted from a personal subscriber station by installing a characteristic determination server for determining service characteristics in a portable Internet system.
