Latest Patents
Chengzhen Sun's latest patents focus on methods, systems, and apparatuses for accessing a visited network. The first patent describes a process where a user accesses a visited network in a wireless telecommunication environment. Upon receiving an access request from the user, the system detects any changes in the selected visited network. An AAA server device then requests authentication and/or authorization information from a Home Subscriber Server (HSS). The HSS checks the user's authorization against a list of authorized visited networks stored within it.
The second patent elaborates on a method for accessing a visited network, where the user selects a network and initiates an access request. The user information application apparatus detects changes in the visited network and retrieves a list of authorized networks from a user information storage apparatus. It then verifies the user's authorization to access the network. If authorized, the user receives an access accept response, allowing them to connect to the visited network. These innovations ensure accurate checks of user authorization for network access.
