Abstract: A method and device for routing data packets of a wireless terminal device in a communication network. When Open system Authentication is used, the system operates similarly as the current Nokia Operator Wireless LAN system, in which the terminal device and the access controller are the parties involved in the authentication. The access controller relays information relating to the authentication between the terminal device and an authenticating server, and it is capable of updating independently the list of users it maintains. When authentication according IEEE 802.1X authentication, the access point operates according to the IEEE 802.1X standard, serving as the authenticating party and relaying information relating to the authentication between the terminal device and the authentication server. In addition, the list maintained by the access controller is updated after a successful authentication, for example by the access point or the authenticating server.

Abstract: A method and device for ensuring address information of a wireless terminal device in a wireless local area network, the network comprising; an access point for setting up a communication connection to the terminal device, the method comprising establishing a communication connection between the terminal device and the access point (101), and relaying data packets from the terminal device to the network and from the network to the terminal device (105). The method further comprising the steps at the access point: detecting an IP address of the terminal device in response to the established communication connection (103), associating the detected IP address of the terminal device to the MAC address of the terminal device (104), and comparing that the address information of the terminal device on the relayed data packets are corresponding to the associated address information (111, 112).
