The present invention relates to a method for connecting a mobile communication terminal to a wireless Internet using a service option. More specifically, when the SO = 33 channel is overloaded, the wireless Internet is connected to the mobile communication terminal through the SO = 15 channel, but moves through the SO = 33 channel when an available channel exists in the SO = 33 channel. A method for providing a wireless Internet service to a communication terminal.

With the rapid development of computer, electronic and communication technologies, 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 terminal user wirelessly, which can provide a service regardless of time and place. In addition, while supplementing a voice call service by providing a text message, a wireless Internet service has recently emerged, which provides an Internet service to a user of a mobile communication terminal through a wireless communication network.

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

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.

However, the existing mobile communication system is expensive to use the base station because of the high base station construction cost, and because the screen size of the mobile communication terminal is limited to provide high-speed wireless Internet, such as limited content available. In addition, wireless local area network (WLAN) technology has limitations in providing it as a public service due to problems such as radio wave interference and narrowness of coverage. As a result, a mobile Internet (Wibro: Wireless Broadband Internet or PI: Portable Internet) system that can use a high-speed wireless Internet service at a low price while moving has emerged.

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

In addition, the mobile Internet system uses a 2.3 GHz frequency band, and in order to effectively use the allocated frequency spectrum, a time division duplex (TDD) is drawn by a duplex method, and a multiple access method is used. Uses Orthogonal Frequency Division Multiple Access (OFDMA).

With the advent of such a portable Internet system, a higher quality internet service than the existing CDMA2000 1x and 1x EV-DO is possible, and various kinds of internet services will be provided based on this.

1 is a flowchart illustrating a message flow between a mobile communication terminal and a base station in a conventional wireless Internet connection.

When the state between the mobile terminal and the base station is in an idle state, that is, when the mobile terminal does not attempt to access the wireless Internet, the base station performs a general page message to perform a paging procedure to the mobile terminal. ) Is transmitted to the mobile communication terminal (S110).

The mobile communication terminal transmits a page response message to the base station in response to the general page message received from the base station (S120). As the mobile communication terminal transmits a page response message to the base station, the base station can confirm that the paging procedure to the mobile communication terminal is normally performed.

To access the wireless Internet, the mobile communication terminal first transmits a S0 = 33 Service Request Message (SO = 33) to the base station in order to check whether the SO = 33 channel is accessible (S130). SO is an abbreviation of Service Option, and is a parameter that defines the property of transmission data in a CDMA mobile communication terminal. In the case of a wireless Internet service, the SO is used to determine the data type, speed, and vocoder bypass. This SO is an important factor that determines the characteristics of the wireless Internet service, and is determined through service negotiation between the mobile communication terminal and the base station for wireless Internet packet service.

Table 1 is a table showing SO values according to data services. As shown in Table 1, since various SO values exist in the same data service, the SO value is specifically managed by the mobile communication terminal and the base station.

S0 = 33 supports the speed of 153.6 Kbps so that the mobile terminal can receive the wireless Internet service. When the mobile communication terminal attempts to access the base station through the wireless Internet, the state between the mobile communication terminal and the base station is changed from the idle state to the traffic state (Traffic State).

At this time, when a plurality of mobile communication terminals are connected to the base station with SO = 33 for wireless Internet data communication and the capacity of the SO = 33 channel of the base station is saturated, the base station sends an SO rejection service response message (Service Response Message, SO: Reject) is transmitted to the mobile communication terminal (S140).

The mobile communication terminal determines that the SO = 33 channel is saturated and transmits an SO = 15 service request message to the base station (S150). SO = 15 is a channel that provides a wireless Internet service to the mobile communication terminal at a speed lower than that of the SO = 33 channel, that is, 14.6 Kbps.

The base station transmits a service response message (Service Response Message, Accept) to notify that the provision of the wireless Internet service through the SO = 15 channel (S160).

The base station transmits a service connect message to the mobile communication terminal to notify that the connection of the wireless Internet data call to the mobile communication terminal is completed through the SO = 15 channel (S170).

In this case, the data service through the SO = 15 channel, that is, the low speed data service, continues until the mobile communication terminal completely terminates and reconnects to the wireless Internet service. Even if the SO = 33 channel is free, the mobile communication terminal must maintain the SO = 15 channel, which may cause a service failure when receiving a service that needs to transmit a large amount of multimedia data. There was a problem running the service.

In order to solve the above problems, the present invention, when the SO = 33 channel is overloaded, so that the wireless Internet access to the mobile communication terminal through the SO = 15 channel, if there is a channel available in the SO = 33 channel An object of the present invention is to provide a method for providing a wireless Internet service to a mobile communication terminal through a SO = 33 channel.

According to a first object of the present invention, there is provided a method of connecting a wireless Internet to a mobile communication terminal using a service option (SO), the method comprising the steps of: (a) performing a paging procedure to the mobile communication terminal; (b) confirming whether the mobile communication terminal can access the wireless Internet through a high speed channel; (c) notifying the mobile terminal of the overload condition when the high speed channel is overloaded; (d) allowing the mobile communication terminal to access the wireless Internet through a low speed channel; (e) notifying the mobile communication terminal when a channel accessible to the high speed channel exists; And (f) allowing the mobile communication terminal to access the wireless internet through the high speed channel.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

As the mobile communication terminal transmits a page response message to the base station, the base station can confirm that the paging procedure to the mobile communication terminal is normally performed.

In order to access the wireless Internet, the mobile communication terminal first transmits a S0 = 33 Service Request Message (SO = 33) to the base station in order to check whether the SO = 33 channel is accessible (S215). SO is an abbreviation of Service Option, and is a parameter that defines the property of transmission data in a CDMA mobile communication terminal. In the case of a wireless Internet service, the SO is used to determine the data type, speed, and vocoder bypass. This SO is an important factor that determines the characteristics of the wireless Internet service, and is determined through service negotiation between the mobile communication terminal and the base station for wireless Internet packet service.

S0 = 33 supports the speed of 153.6 Kbps so that the mobile terminal can receive the wireless Internet service. When the mobile communication terminal attempts to access the base station through the wireless Internet, the state between the mobile communication terminal and the base station is changed from the idle state to the traffic state (Traffic State).
