Network switching authentication method

Abstract

The invention provides multiple network switching authentication methods, wherein one network switching authentication method is executed by user equipment, and applicable to switching from a cellularnetwork wireless access technology to a wireless local area network technology. The network switching authentication method comprises the steps of starting an authentication process of the wireless local area network technology; during an authentication process period of the wireless local area network technology, monitoring signal quality of the wireless local area network technology; accordingto the monitored signal quality of the wireless local area network technology, judging whether to interrupt the authentication process of the wireless local area network technology; and when the signal quality of the wireless local area network technology indicates that the switching is not suitable for being continuously performed, interrupting the authentication process of the wireless local area network technology. The network switching authentication method has the advantage that during a network switching process in interaction work between the cellular radio access technology and the wireless local area network technology, when the signal quality of the wireless local area network is not good, the authentication process of the wireless local area network can be interrupted in time, and the waste of time and resources can be reduced.

Description

technical field [0001] The present invention relates to a communication device and an operation method thereof, more specifically, relates to a communication device in a cellular network (Cellular Network) radio access technology (Radio Access Technology, RAT) and a wireless local area network technology (Wireless Local Area Network, WLAN) The authentication method when performing network handover in interworking. Background technique [0002] With the rapid development of wireless communication technologies, communication devices can simultaneously support multiple cellular network radio access technologies (for example, 3G WCDMA / TD-SCDMA / CDMA2000 technology specified by 3GPP, 4G LTE technology, etc.) and WLAN technologies (for example, Wi-Fi technology, etc., where Wi-Fi is also called wireless fidelity technology), and further development of communication devices has appeared in a variety of cellular network radio access technologies (such as LTE technology) and wireless ...

AI Technical Summary

Problems solved by technology

However, during this period of time, the signal quality of both cellular network radio access technologies (such as LTE) and wireless LAN technologies (such as Wi-Fi) may change, and may no longer be suitable for switching

Therefore, for the handover authentication process in the interworking between the cellular network and the wireless local area network, it will cause a waste of time and resources.
