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.

Method and apparatus for authentication in a wireless telecommunications system

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 (), and relaying data packets from the terminal device to the network and from the network to the terminal device (). 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 (), associating the detected IP address of the terminal device to the MAC address of the terminal device (), and comparing that the address information of the terminal device on the relayed data packets are corresponding to the associated address information ().

Method and apparatus for ensuring address information of a wireless terminal device in communications network

The invention relates to a method and system for authenticating a user of a data transfer device (such as a terminal in a wireless local area network, i.e. WLAN). The method comprises: setting up a data transfer connection from the data transfer device to a service access point. Next, identification data of the mobile subscriber (for example an MSISDN) are inputted to the service access point. This is followed by checking from the mobile communications system whether the mobile subscriber identification data contains an access right to the service access point. If a valid access right exists, a password is generated, then transmitted to a subscriber terminal (for example a GSM mobile phone) corresponding to the mobile subscriber identification data, and login from the data transfer device to the service access point takes place with the password transmitted to the subscriber terminal.

Method and system for authenticating user of data transfer device

A method for performing authentication in a communication system comprising an authentication server, and a user profile store storing user profiles for users of the communication system, the method comprising: transmitting from the authentication server to the user profile store a request for the user profile of a user; receiving at the authentication server a response to the request; determining whether the response is indicative of an error; and if the response is indicative of an error, transmitting from the authentication server to the user profile store a message of a type such as to trigger the user profile store to perform a location update procedure in respect of the user.

Performing authentication

A method and computer program to manage the load on a packet switched network so that the quality of VoIP transmission does not degrade with the addition of a new VoIP calls. This method and computer program determines the carrying capacity of the communications lines based on the bandwidth and TRAU frames per packet. Further, this method and computer program may determine the state of the network based on round trips times to nodes or computer gateways on the network. In either case calls are admitted only when doing do would not cause the quality of all VoIP calls to degrade.
