WLAN UE Network Reselection via Pre-stored Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WLAN UE systems lack a specific scheme for efficiently reselecting mobile communication networks when multiple networks are connected, leading to issues such as high charges, restricted access, or the need for different data transmission rates, which existing technologies do not adequately address.
Innovation Solution
The method involves a WLAN UE sending authentication information to its Home Network via a WLAN Access Network to access a new Visited Mobile Communication Network, with the Home Network authenticating and sending an access instruction, allowing the UE to seamlessly switch to the new network without disconnecting from the previous one, thus enabling smooth re-selection and multiple connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If WLAN UE uses existing network selection schemes, then network access is possible, but connection downtime increases and user satisfaction decreases
Solution Approach 1:
The patent applies preliminary action by pre-establishing authentication relationships between the WLAN UE and multiple Visited Mobile Communication Networks before actual network switching is needed. The UE stores authentication information for multiple networks in advance, so when network reselection is required, it can immediately use the pre-stored credentials to connect without interruption, eliminating connection downtime and maintaining continuous service.
2Adaptability or versatility
If WLAN UE reselects mobile communication networks frequently, then access requirements are met, but charging accuracy decreases and operator profits are affected
Solution Approach 1:
The patent implements feedback mechanisms where the network side (Visited Mobile Communication Networks and Home Network) monitors and manages the UE's network reselection behavior. The system provides feedback on charging information and network selection decisions, enabling accurate tracking of data transmission volumes across different networks. This feedback loop ensures that even with frequent reselections, the charging system maintains precision by continuously receiving updated information about actual network usage patterns.

AI summary
The present invention discloses an interactive method for a WLAN UE accessing a new operation network, which comprises: when the WLAN UE which has accessed a first Visited Mobile Communication Network needs to re-select a second Visited Mobile Communication Network to access, the WLAN UE sending authentication information to a Home Network of the WLAN UE through a WLAN Access Network and the second Visited Mobile Communication Network; after receiving the authentication information, the Home Network of the WLAN UE authenticate the WLAN UE according to the authentication information via the second Visited Mobile Communication Network, and sending an access instruction to the WLAN Access Network through the second Visited Mobile Communication Network; and on receiving the access instruction, the WLAN UE accesses the second Visited Mobile Communication Network via the WLAN Access Network. The method enables a WLAN UE to reselect another Visited Mobile Communication Network after accessing a Visited Mobile Communication Network.
