A mobile terminal transmits an N-th authentication key to an authentication server when the mobile terminal has moved from a coverage area under a certain radio access point to a coverage area under another radio access point. The N-th authentication key is generated by applying a hash function to a random number a number of times one smaller than an (N−1)th authentication key which was transmitted when the mobile terminal moved to the coverage area under the certain radio access point. Upon receipt of the N-th authentication key from the mobile terminal, the authentication server applies the hash function once to the N-th authentication key, and compares the result with the (N−1)th authentication key. Then, the authentication server determines that the authentication is successful when there is a match between both keys.

An improved connectivity to radio access point is enabled by a server that includes a database storing data about various radio access points, and an evaluation module evaluating the quality of connection to each of the access points. Clients receive updates about relevant access points from the server and use the information to connect to the preferred access point. The clients also check connectivity to other access points in the vicinity, and report the findings to the server. The server uses the reports to update its database, and send corresponding updates to the clients.

A method for changing a route in wireless communication involves: when there is subscriber equipment requesting a change of route in a cell, a base station negotiates downlink measurement contents with a relay station facilitating the route change in the cell; a network side informs the subscriber equipment requesting a change of route of the negotiated downlink measurement contents, and the subscriber equipment executes a downlink measurement according to the received measurement contents and reports the downlink measurement results to a radio access point; and the radio access point executes the route change for said subscriber equipment according to the received measurement results. The method can effectively improve the accuracy of the route change and alleviate the delay due to the route change.

There is provided methods, devices and computer program products for distributing a plurality of virtual IEEE 802.11 wireless networks through a heterogeneous infrastructure. A terminal sends a service provider request to an access point. The service provider request is forwarded to a master server which searches for available service providers. Acknowledgement information relating to available service providers capable of operatively connecting the terminal to the data communications network via the access point is sent by the master server to the access point. The access point forwards this information to the terminal. The access point may thus distribute a plurality of virtual IEEE 802.11 wireless networks, their number only constrained by the number of distinct identifiable service providers and the memory of the master server. A data connection may be established in the absence of a direct service agreement between the service provider of the terminal and the operator of the access point.

Provisioning remote access points for use in a telecommunication network. A remote access point contains identity information established during manufacturing; this identity information may be in the nature of a digital certificate. The identity information is stored in the remote access point, and may be stored in a Trusted Platform Module if present. When the remote access node is powered up in unprovisioned state, outside the manufacturing environment, it attempts to establish an internet connection via a first wired interface, and queries a user for information representing the TCP/IP address of its controller via a second wired interface. Once an internet connection is present, and a TCP/IP address has been provided, the remote access point attempts to connect to the controller at that address. The controller may filter connection requests through a whitelist of approved remote access points. Once a connection is established, controller and access point exchange and verify each other's identities. This may be done through the exchange and verification of digital certificates. Provisioning information is downloaded from controller to remote access point and installed. This may be done via a tunnel such as an encrypted tunnel. Software updates may be applied. The provisioned remote access point is placed in operation.

A mobile terminal (10) in a radio access system detects communication quality such as frequency of retransmission, packet error rate, etc. on an RLP-based radio link, and converts the communication quality into a traffic class in IP or a window size in TCP. Based on the thus converted communication quality, flow control is performed at IP or TCP. At a radio access point (12) also, quality information is extracted from an IP header or a TCP header, and the number of packets into which the IP or TCP packet is to be fragmented, retransmission count, etc. are set based on the extracted information.
