摘要： Cordless access over an extended area is provided by a network of co-operating wireless access points (10, 20, 30) etc all operating on a common channel, such that continuous communication with a mobile handset (9) is possible within the combined coverage of the set of access points. The access points are all recognised by the handset (9) as being part of the same connection. The access points are in communication with each other, either by wireless connections (11, 51) or by wired connections (21, 41), so that they can communicate between each other, a home base site controller 60, and a connection (31) to the public network. Under the control of the HBSC (60), all the access points (10, 20), broadcast a common service set identifier SSID and operate on the channel selected by the HBSC (60), and consequently a communications session can continue seamlessly, regardless of which access point is currently in use. The HBSC (60), on receiving a data transmission addressed to a specified handset (9), forwards it to any access points (20, 40) directly connected to it. A method is disclosed for setting up the access points (10, 20, 30) to form the wireless network.

摘要： The nodes (200, 201), etc in a hierarchical network are also capable of forming direct wireless connections between each other. Each node checks on a regular basis to determine whether its network connection is intact. If a node (211) discovers that its direct broadband connection (31, 21, 33, 24, 34) to the exchange (2) has failed, it autonomously communicates with other nodes (201, 202, 212, 220) in the physical neighbourhood, using its wireless capability. It first searches for a path through a WIFI connection to its immediate neighbours in the hierarchy to attempt to reach a working node (210, 212) connected to the same Distribution Point (21). (These are not necessarily the nearest neighbours in the wireless network). The nodes collect and store connectivity data on neighbouring nodes, and exchange connectivity data between themselves to identify nodes, and groups of nodes, that are not currently connected to the branched network. Within each group of nodes which have exchanged connectivity information, one of the group is selected to transmit a report on connectivity to the network control centre, the remaining members of the group being suppressed from transmitting such reports. If it is not itself connected to the hierarchical network, the selected node (211) can now use the connection (37) to the closest working node (220) and its broadband connection (22, 25) to the network control centre (2) to inform the network operator of the fault and its likely location. If the nodes have formed two or more separate ad hoc networks, (e.g link 35 being absent) the information from the separate networks is aggregated at the network control centre (2) to identify failure points in the hierachical network.

摘要： Requests (94) for location-dependant information, received from a mobile device (1) having a location-finding capability (10), are processed by middleware (4, 40) which identifies the handset type and generates instructions (93, 95) specific to the handset type to provide the data (94, 97) required to generate the required data (99) in a format compatible with the handset (1).

摘要： Virtual dedicated voice connections between parties 18, 19 to a packet switched system can be created by reserving capacity for such connections in the packet switched system. The capacity reservable by any one party is limited, to prevent oversubscription of resources in the packet switched. The system incorporates a call admission control processor 12, 17 for controlling access to the packet switched call routing system such that a voice call attempt is successful only if capacity for such a dedicated connection has previously been reserved. The capacity reserved for the virtual connections is made available for use by other traffic when not required for voice sessions.
摘要翻译：可以通过在分组交换系统中保留这种连接的容量来创建分组交换系统的各方18,19之间的虚拟专用语音连接。任何一方可以保留的容量有限，以防止分组交换中的资源超额预订。该系统包括用于控制对分组交换呼叫路由系统的接入的呼叫许可控制处理器12,17，使得只有当这种专用连接的容量先前被保留时，语音呼叫尝试才成功。为虚拟连接保留的容量在语音会话不需要时可供其他流量使用。

摘要： A virtual private data network is overlain on an internet connection to allow prioritisation of connection between two or more specified terminations over a switched network, thereby minimising latency in the system. Data to be transmitted between the specified terminations is identified by a weighting prefix and its routing is prioritised over other data for the same destination termination.

摘要： Embodiments of the invention relate to computer-implemented methods of indexing documents in a document repositoiy (210-212) comprising splitting the documents (D1-D3) into subdocuments (Dla-D3d), each subdocument relating to a theme, by identifying semantic relationships between entities in the document and determining changes in theme at least in part on the basis of the distribution of semantically-related entities, and performing an indexing operation by generating and storing, in a searchable index, metadata associated with the respective subdocuments. Embodiments of the invention also relate to retrieving documents of interest from a document repository (210-212), including indexing documents according to the aforementioned method, submitting a search context, using the search context, on the basis of the categories that have been associated with the subdocuments, to identify documents of interest by reference to the metadata, and returning information relating to the identified documents of interest.

摘要： A device is operable to use received signals to divide time into a succession of frames, each frame having plural consecutive timeslots, and into a succession of four or more superframes. A transmitter is operated only in a single timeslot in one frame. A receiver is operated in the other timeslots in the frame and for all timeslots of immediately preceding and following frames, and in no other frames. This allows devices to predict periods in which to hibernate or carry out intensive tasks. The device determines which timeslots of the first frame are occupied to provide local awareness information, and transmits it as a code on its transmit timeslot along with payload data. This allows other devices in a network to obtain information about their local environment and about the environment of their neighbours. Routing decisions are made on this basis.
摘要翻译：设备可操作以使用接收到的信号将时间划分成一连串的帧，每个帧具有多个连续的时隙，并且进入一连串的四个或更多个超帧。一个发射机只能在一个时隙内工作。接收机在帧中的其他时隙以及紧接在前一帧和后续帧的所有时隙以及没有其他帧中操作。这允许设备预测休眠或执行强化任务的时段。该设备确定第一帧的哪些时隙被占用以提供本地感知信息，并且将其作为其发送时隙上的码与有效载荷数据一起发送。这允许网络中的其他设备获取有关其本地环境和其邻居环境的信息。路由决定是在此基础上进行的。

摘要： A system is monitored for event reports, which are delivered and stored in a first database (12). Data flood conditions are identified by monitoring this database (12) to identify event reports having predetermined characteristics whose occurrence exceeds a predetermined flood threshold value, such characteristics being stored in a second database (13). The data flood conditions are contained by retrieving the stored characteristics from the second database (13) and purging the first database (12) of event reports having those characteristics.

摘要： A networked collection of environmental telemetry sensors (10, 11, 12, 13……..) use data derived from received wireless signals both for supporting data communications and for characterisation of environmental phenomena. The sensors are arranged to float in the ocean and form an ad hoc communications network to exchange oceanographic data with each other. Ocean waves cause attenuation or other impairments of the signals transmitted between the sensors, which result in measurable impairment to the signals received by each transceiver. Such impairment is measured by the individual transceivers and collected as environmental data. The invention is also applicable to the measurement of other environmental data that influence propagation properties, such as human or animal activity, traffic movement and congestion, etc.

摘要： The demodulation process of a wireless data transmission system using multi-level symbols makes use of templates corresponding to each of the possible symbol transitions, so that knowledge of previously decoded symbols can be use to decode the next one. An estimation and correction loop provides for initial estimation of the values of a plurality of consecutive symbols, and error estimates are made for the estimated initial values of the symbols and for one or more alternative values, a final estimate being determined to minimise the total estimated error.
