Novel approach for PLC impulsive noise modelling

Abstract: The electrical appliances shared with PLC modems in the same powerline network generate noises. Among them, impulsive noises are the main source of interference resulting in signal distortions and bit errors during data transmission. Many impulsive noise models were proposed in the literature. They share the same impulsive noise definition: “unpredictable noises measured at the receiver side”. This definition leads to the modelling of thousands of impulsive noises whose plurality would very likely come from the diversity of paths that the original impulsive noise took. In this paper, an innovative modelling approach is applied to impulsive noises which are henceforth studied directly at their sources. Noise at the receiver is considered as the noise model at the source filtered by the powerline channel. Effective in-device sources of impulsive noises are identified and classified into six classes, from which representative noises are proposed. Based on impulsive modelling at source, a receiver side model is finally proposed.

System and method for managing virtual user domains

Abstract: The present invention addresses the previous of lack of subscriber identity tracking and management for residential broadband lines and provides customized access and enhanced IP services for a subscriber's household members (virtual user domain) and his/her circle of extended families, relatives, and friends (multiple virtual user domains). Rather than treating a broadband link as a single connection with a single set of services and quality constraints, the present invention enables the subscriber to create multiple user profiles per broadband link; tailor activities such as web services to a specific user and group profile; provide restricted access to minors (e.g. allow only age appropriate content to be viewed); and facilitate connection at multiple access points on a carrier's edge network.

Instant message tagging

Abstract: A messaging system having a portion for receiving a message, a portion for associating a context tag with the message, and a portion for providing the message with the associated context tag if the message is transferred to a client during a messaging exchange. In one embodiment, the system may include a context provider for analyzing the massage and identifying the context tag. The context provider may identify a noun and/or verb contained within the message and provide the identified noun and/or verb as the context tag. The context tag may be provided automatically without user intervention or one or more context tags may be provided for selection by a user.

Interworking of WLAN and 3G systems

Abstract: Interoperation of different fixed and mobile networks is one key feature of systems beyond 3G, specifically between wireless local area networks, covering hot-spots with high data rates, and mobile cellular systems with full coverage. This comprises the vertical handover, i.e. the handover between systems with different air-interfaces, which are investigated in the paper. In contrast to several approaches that investigate solutions for the IP layer, the focus of the paper is on mechanisms on the link layer to improve the handover, respectively scanning other air-interfaces, measurements and appropriate triggers from the link layer that are considered in the handover decision process. Finally, the benefits for the handover performance are indicated and the potential of the proposed new concepts is highlighted.

Extending and unifying chronicle representation with event counters

Abstract: This paper is dedicated to the chronicle recognition approach used to design an evolution monitoring system for supervising dynamic systems for which time information is relevant. We propose to extend and also to unify the chronicle representation through event counters. The main motivation of such an extension of the chronicle representation arises from alarm processing: counting the occurrences of alarms can be useful to evaluate the severity of a problem and also to discriminate some kind of faults. The paper describes the representation and the corresponding algorithms for processing this extension according to the purpose of supervision in terms of performance.
