Description

Method and apparatus for providing wireless data service using wired / wireless hybrid network {Method for providing wireless data service using wired and wireless communication network and Apparatus

The present invention relates to the provision of a wireless data service, and more particularly, to a method and apparatus for providing a wireless data service using a wireless communication and a wired communication network.

The wireless mobile communication method can be divided into CDMA and WCDMA.

Code division multiple access (CDMA) is a digital mobile communication method using spread-band technology developed by Qualcomm of the United States, and is a type of multiple access method using spread-band technology. Spread-band communication refers to spreading and spreading a signal with a much wider bandwidth of a signal to be transmitted. Since the signal has a low power density, it is difficult to detect the presence or absence of a signal. In addition, in order to generate the original signal in the process of despreading the received signal, in this case, it is guaranteed because the code used for spreading must be known exactly. .

Multiple access technology is a method of sharing limited resources among many users, such as frequency division, time division, space division, polar division, and code division. However, other methods except for code division are orthogonal division in each physical domain, so that there is no interference between users, but in the case of code division, the interference is large because only division is performed by code.

Wideband code division multiple access (WCDMA) is a wideband CDMA scheme. The wider the bandwidth, the more selective and the higher the data throughput, the higher the processing gain. Therefore, the interference is reduced and the capacity is increased. In addition, since multipath can be decomposed using RAKE, it is possible to overcome in indoor environment even in the case of micro cell. In addition, the bandwidth efficiency per 1MHz bandwidth is excellent, which is advantageous in terms of capacity, and the processing gain is increased to reduce the capacity of, thereby reducing the cost of implementation, and reducing the power consumption and size of the power amplifier by reducing the size of the power amplifier.

A base station controller (BSC) manages multiple base stations, interworking with a mobile switching center (MSC), and some control stations provide interworking functions with PDSN for 2.5G / 3G data services.

A packet control function (PCF) includes a control control unit and a bearer processing unit, and is connected to a base station and connected to an authentication / authorization and accounting server (AAA) to control packet services.

PDSN (Packet Data Serving Node) is a router for providing 2.5G / 3G data services, and is in charge of authorization / authentication / billing, packet routing, handover, and QoS for receiving packet services. The mobile communication network AAA server 130 is responsible for authorization / authentication for accessing the mobile communication network and performs charging of the terminal.

Here, the user terminal 100 communicates with the BTS / BSC / PCF 110 and the BTS / BSC / PCF 110 receives a signal for the user terminal 100 to access a wireless communication network. In addition, the PDNS 120 passes the authentication (S154, S156) for accessing the mobile communication network from the mobile communication network AAA server 130 through a point-to-point protocol (PPP) negotiation process and then sends an IP address toward the terminal. It allocates (S152).

Referring to FIG. 2, when the user terminal 100 enters a building or a home where a wired / wireless access point (AP) is called, the user terminal receives a signal of a wired / wireless AP in a building or home. Will be detected. Thereafter, when the user terminal 100 starts a data service, the user terminal 100 attempts to process a wireless communication network access signal to the wired / wireless AP, and the wired / wireless AP performs a role of BTS / BSC / PCF / PDSN of the existing communication network instead. That is, the present invention is disclosed from the wired / wireless AP receiving a request for a wireless communication network access signal from the user terminal 100 (S210).

The wired / wireless AP 300 transmits authentication request information to a wired / wireless gateway (hereinafter referred to as 'G // W') so that the mobile communication network AAA server 130 authenticates the user terminal 100 (S220). ). The authentication request information may be an identification number of the user terminal 100 or subscriber identification information stored in the mobile communication network AAA server 130.

That is, the wired / wireless G / W 320 makes a request for access to the mobile communication network AAA server 332 (S430), and receives the corresponding subscriber authentication result (S432).

When the subscriber of the user terminal 100 is a valid subscriber, the wired / wireless G / W 320 transmits a VPN generation request response signal including the valid information to the wired / wireless AP 300 (S412). Terminate signal processing for VPN creation.

When the authentication is normally performed, the wired / wireless G / W 320 allocates a tunnel IP address so that the user terminal 100 can access the data (S420). A VPN is formed in the wired communication network 312 using the tunnel IP address. Therefore, the actual call processing is performed in the wired communication network 312, which enables high-capacity data processing, and overcomes the limitation of radio resources in which the speed of data service is slowed in a building or home.

The mobile communication network interworks with the application server 140 to provide a wireless data service (S440).
