Abstract  Abstract

PROBLEM TO BE SOLVED: To make manageable the address allocation of a mobile terminal in WLAN (wireless local area network) interconnection in a wireless LAN (local area network) environment for mobile users visiting from other networks.

SOLUTION: By using an access control framework the mobile terminal obtains an address together with the granting of access to a service to be able to set up a tunnel. Just by exchanging a message back and forth once between the mobile terminal and the home domain server address management tunnel setup and service granting are achieved. A management process is protected by encryption peculiar to an access control process and the need of extra security setup procedures is eliminated. Further by using granting procedure the address connected to a service session is acquired. Even in the case of accessing multiple parallel sessions the mobile terminal maintains the multiple addresses. Also the address management is integrated with a policy control mechanism.
