Method for accessing 3G-WLAN internet

Abstract

The invention discloses a method for accessing 3G-WLAN internet, comprising two-way authentication method of WLAN, UE and 3G network, re-direction attacking method of impersonation resisting WLAN accessing network, off-line mobile subscriber charging method and localized re-authentication method in the WLAN network. The method adopts 1-15 concrete executing steps; the method is based on the authentication protocol under the interlinked loose coupling way of the WLAN and WCDMA, and utilizes rapid authentication protocol under off-line charging mechanism and localized re-authentication of the re-authentication process, so as to avoid the potential re-direction attacking action, and effectively reduce the time delay when in roaming switch of the mobile subscriber, thus being a safe and quick method for accessing 3G-WLAN internet.

Description

technical field [0001] The invention relates to an internet access technology, in particular to a method for quickly and safely accessing a 3G-WLAN internet. Background technique [0002] With the development and popularization of the global communication industry, 3G wireless network has gradually become the mainstream new technology in the market, and WLAN, as a broadband access method of 3G network in hotspot areas, has also become an efficient application mode. 3GPP has proposed two completely different schemes for the interconnection between WCDMA and WLAN, which are called "tightly coupled interconnection" and "loosely coupled interconnection". With the WLAN wireless interface as the bearer of WCDMA, all WLANs must pass through the WCDMA core network, but the reconfiguration is too complicated and the cost is too expensive, resulting in the lack of competitiveness of tightly coupled interconnection technologies. Loosely coupled interconnection technology or mechanism ...

AI Technical Summary

Problems solved by technology

This will bring a large delay to mobile users' roaming, handover, and key update behaviors in the WLAN network, and will also affect the continuity and mobility of mobile user services.

In a word, the disadvantages of the Internet access method in the prior art are: 1. Potential Re-direction attack behavior exists; 2. Long delay in the re-authentication process
