Abstract: The present application relates to a user accessing to a visited network in a wireless telecommunication network. After receiving an access request from the user for selecting a visited network and detecting the visited network selected by the user has changed, an AAA server device initiates a request for obtaining authentication and/or authorization information of the user from a HSS. In the process of obtaining the authentication and/or authorization information, the HSS checks whether the user is authorized to access to the visited network according to a list of authorized visited networks stored in the HSS.

Abstract: A method for processing a service connection between a user terminal and a Wireless Local Area Network (WLAN) is provided. A WLAN interactive network includes at least a WLAN user terminal, a WLAN access unit, a service control unit and a user information storage unit. The method includes setting flags that represent the attached or detached status of the service connection between the user terminal and the WLAN in the WLAN user terminal and the service control unit respectively; and establishing or canceling the connection between the user terminal and the network through the interaction between the WLAN user terminal and the WLAN, meanwhile modifying the corresponding flags.

Abstract: An interacting method for WLAN UE selecting a mobile communication network to access in WLAN is disclosed. The method includes: a WLAN UE judges whether the identity information of the WLAN AN exists in the WLAN identity information stored when mobile connection with the WLAN AN is established, if so, the network selection information corresponding to the identity of the WLAN stored will be sent to the WLAN AN, otherwise, a pre-configured mobile communication network with highest priority is regarded as network selection information to be sent to the WLAN AN; the WLAN AN identifies the mobile communication network to access according to the network selection information carried in Authentication Request, and connects the WLAN UE to the selected network to implement authentication.
