Abstract: In a network of data devices having routing functions, a controller within the network core is arranged to monitor the status and capabalities of each data device and to check for the availability of network functions which alter the capabilities of the data devices. The controller changes the configuration of the data devices to gain the new functionality, or alters the routing behavior so that certain control data packets are forwarded to a function processor which performs processing on behalf of the data devices in a proxy manner. The function processor provides virtual functions to the data devices.

Abstract: The disclosure relates to a dual network access point capable of establishing a home wireless network and a further secondary wireless network for a number of wireless devices. The first wireless network is a private home WLAN while the second wireless network is a guest network or a hotspot network. To prevent secondary network users impacting the performance of the first network, the access point monitors the devices connected to the first network and adjusts the advertised minimum supportable rate on the second network.

Abstract: In a Proxy Mobile IPv6 (PMIP) network, a mobile node can roam between different access networks while maintaining a consistent IP address for session continuity. To provide access to a user's home LAN resources, even when the user's mobile node is not directly attached to the home LAN, a local mobility anchor and mobility access gateway are configured to authenticate the mobile node credentials and if authorized, to provide access to the user's LAN resources by via data tunnels and routing table reconfigurations.

Abstract: In a hotspot Wi-Fi network, users can access the Internet from a variety of access points. The users' credentials are centrally authenticated within the network core to ensure they are allowed on the hotspot network. To improve security and provide selective access, a further authenticator function in the network manages access to private and/or restricted network resources.

Abstract: Embodiments provide a traffic control system for WLAN access points. The traffic control system works in dependence on a first input-user priority (supplied by an authentication server). This allows different service levels to be provided to different classes of customer. In addition, the traffic control system polices and/or shapes traffic based on a second input—a modulation rate detector, which measures the modulation rate at which each connected client is sending its traffic, and uses it to indirectly cause fairer use of the available air interface capacity (e.g. by causing TCP streams to back off when they detect packet loss). Finally, for some embodiments where public Wi-Fi is being delivered through private Wi-Fi access points, the traffic control system is to manage the air interface utilization split between public and private WiFi users, to ensure that private users do not have their Wi-Fi air interface network capacity unduly impaired by public users.

Abstract: A voice platform monitors a conversation between a call center agent and a caller to identify any predetermined keywords or phrases used in the conversation therebetween. These keywords or phrases can then be used to interface into an existing knowledge management system in order to allow information from the system to be pushed to the agent, thus improving agent efficiency. In a preferred embodiment additional processing is provided which generates an information item score based in the detected keywords or phrases, and those information items with the highest scores are then pushed to the agent, by displaying shortcuts to the information to the agent in the form of a shortcut tree.

Abstract: A speech recognition system recognizes connected speech using a plurality of vocabulary nodes, at least one of which has an associated signature. In use, partial recognition paths are examined at decision nodes intermediate the beginning and end of the recognition path, each decision node having an associated set of valid accumulated signatures. A token received by a decision node is only propagated if the accumulated signature of that token is one of those in the set of valid accumulated signatures associated with that decision node.
