Abstract: An access authentication system is provided for authenticating access for visitors to a wireless local area network (W-LAN), the operator of which administers a visitor authentication, authorisation and accounting (VAAA) server. A user requesting visiting access to the W-LAN, is required to have a valid cellular mobile account, a portable computing device with a browser and a valid W-LAN card from another operator that administers a home authentication, authorisation and accounting (HAAA) server. The user, on requesting visiting access to the W-LAN, inputs, via the VAAA server, identity information that enables the HAAA to issue a personal identification number (PIN) which is encoded and forwarded, preferably by way of a short message service (SMS), to the user's mobile telephone.

Abstract: The invention provides an operating protocol for Local Area Network (LAN) systems capable of coping with the problems of user-mobility between LANs. Such mobility is afforded particularly by wireless LAN (WLAN) systems, whereby a user subscribing to a LAN operated by a so-called Home Operator connects, as a “visitor”, to one or more other LAN sites; basing such connection, for charging and other operational purposes, on that user's subscription with its Home Operator. The inventive protocol links a user's identity with the address of the Home Operator, and stores this information at the visited LAN site, thereby permitting a visiting user, once authenticated by user-interaction, as a visitor with regard to a particular LAN, to revisit that LAN for as long as its authentication with the Home Operator remains sound, without the need for further user intervention.

Abstract: A system is described for delivering information services to the users of Local Area Networks (LANs), and more particularly of wireless LANs (W-LANs), which readily lend themselves to usage in large-scale installations and which support considerable user-mobility around the installation. In order to provide improved delivery to mobile users of location-specific information services, the system is provided with a plurality of wireless access points, distributed around the installation. The system can identify an access point receiving an information request from a mobile user, and can correlate the position of that access point with that of at least one other access point and/or with the position of at least one other feature of the site covered by the W-LAN installation, depending upon the nature of the request. The correlated positional information can be used to determine at least part of the information content supplied to the mobile user.

Abstract: Described herein is apparatus and method for implementing location specific congestion control in a transmission control protocol (TCP) connection. The TCP connection extends between an internet connection (12) and one or more mobile terminals (22, 24, 26). Each mobile terminal (22, 24, 26) is connected to a base station (18) which is then connected to the internet connection (12). An enhancer (14) is provided in the TCP connection to divide it into two connections (16, 20) so that congestion control can be implemented in the connection (16) remote from the mobile terminals (22, 24, 26). There is no requirement of congestion control between the base station (18) and the mobile terminals (22, 24, 26) as they comprise point-to-point connections. The enhancer (14) may be co-located with the base station (18).

Abstract: Described herein is a method for improving the performance of long latency or error prone links without reconfiguration. A host (10) is connected to an external network (20) by means of a satellite connection (30). A first router (40) and a first transparent cache (60) are associated with the host (10). Similarly, a second router (50) and a second transparent cache (70) are associated with the external network (20). When the host (10) sends a domain name server query, it is intercepted by the first router (40) and sent to the first transparent cache (60). If the first transparent cache (60) has the answer, it is passed back to the host (10) via the first router (40). If the first transparent cache (60) does not have the answer, the first router (40) passes the query to the second router (50) via the satellite (30) which passes it onto the second transparent cache (70) which supplies the answer if it has it. Otherwise, the router (50) passes the query to the external network (20).
