Since the wireless network has been commercialized Code Division Multiple Access (CDMA) network, which uses mobile phones as the main communication service, the wireless data access method also uses ISMS (Information Security Management System) or WAP / ME (Wireless Application Protocol /). Mobile Explorer) is the majority.

However, wireless data access requires a high data access fee using a CDMA channel even though data is transmitted at a much lower rate than wired data access, so wireless communication systems are a universal communication service for the public. There was not enough to provide.

Recently, 2.4 GHz Wireless Local Area Network (W-LAN), which uses wireless data network as the main communication service, has been installed in hot spot areas such as hotels, airports, and stadiums. Multi-mode integrated wireless terminal is being released.

The multi-mode integrated wireless terminal supports each wireless network access standard (frequency, modulation / demodulation method, MAC, etc.) to provide two heterogeneous wireless communication services, that is, 800 MHz or 1.9 GHz CDMA mobile telephone service and 2.4 GHz wireless network service. Implemented wireless modem and corresponding protocol are installed respectively and connected to the wireless network according to user's service purpose.

Therefore, when a subscriber with a multi-mode integrated wireless terminal attempts wireless data access in an area where two or more wireless networks are accessible, the subscriber selects a valid service network at this moment without any information about the data quality of each wireless network. Should be.

If there are two or more identified wireless networks, a plurality of wireless data qualities are displayed on the multi-mode integrated wireless terminal and awaiting the user's selection.

In addition, in the above-described process, when the wireless network capable of wireless data access is the only process, the present invention may be displayed to the user and automatically provided with the wireless network connection without waiting for the user's selection.

2 is a flowchart illustrating a method for automatically accessing wireless data in a multi-radio network environment according to the present invention.

As shown in FIG. 2, first, when a user attempts to access a wireless data with a multi-mode integrated wireless terminal providing a multi-radio network connection (21), the wireless terminal can provide all wireless networks that can be provided by the wireless terminal at the current location. Receiving the broadcast signal transmitted from the base station of the to determine the number (N) of wireless networks accessible in the location area from the signal (22).

Subsequently, the number of accessible wireless networks (N) is checked (23), and when there is no wireless network determined to be accessible (N = 0), it is determined that wireless data connection at the corresponding location is impossible (231). The screen may indicate that wireless data connection is not possible.

On the other hand, if it is determined that the accessible wireless network is unique (N = 1), the connection is determined to the corresponding wireless network (232), and the mobile network connection attempt may be automatically started while displaying it on the user screen. In this case, when there are two or more accessible wireless networks, the multi-mode integrated wireless terminal calculates the wireless data quality that can be provided to the user when connected to each wireless network at the corresponding location using the wireless modem processor of each model built in the wireless terminal. (24).                     

Here, the wireless data quality may include a data transmission rate, etc., which is based on the theory of calculating the digital communication transmission capacity between the wireless network base station apparatus of each model and the wireless modem of the terminal apparatus.

Subsequently, the multi-mode integrated wireless terminal of the user checks whether there is a requirement set in advance by the user in the terminal (25). At this time, the user's requirements are the user's preferred wireless network or the preferred wireless data quality. This may be included. If there is no requirement set by the user, the wireless terminal displays at least two accessible wireless networks and wireless data quality calculated in the above step on the user screen (251), and waits for the user's selection (252). ).

However, if there is a requirement set by the user, the wireless terminal compares the number of wireless networks (M) whether the calculated two or more accessible wireless networks or the wireless data quality of the corresponding wireless network satisfies the requirements of the user ( 26).

As a result of the comparison, if there is no accessible wireless network that satisfies the user's requirements (M = 0), the wireless terminal indicates that there is no wireless network that satisfies the user's request on the user screen (261), and helps the user to select later. In order to display the accessible wireless network and the wireless data quality on the user screen (27), the user waits for selection (28). At this time, if the only wireless network that accepts the user's request (M = 1), the wireless terminal is determined to be connected to the wireless network (262) is displayed on the user screen and may attempt to automatically access the wireless network.

However, if there are two or more wireless networks that can accommodate the user's requirements (M ≥ 2), the user terminal displays two or more accessible wireless networks and wireless data quality that satisfies this on the user screen (27). Wait 28 for user selection.

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 embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention provides wireless data quality and user requirements that can be provided in each wireless network type that can provide a user using a multi-mode wireless network as a multi-mode integrated wireless terminal at a location where a wireless data connection is attempted. By considering the automatic access to the service wireless network or automatically accessing the wireless data access service network according to the user's easy selection, the rational use of wireless network resources and the convenience of the user are provided, and the position of the operator providing the wireless network. In addition, it is possible to provide a kind of service level agreement (SLA) function, as customers can check the quality of service that can be provided when accessing their wireless network from the location in advance and quickly check the quality of the failure and network. There is.
