Method and system for the improvement of the QoS support in the de-centrally organized wireless networks

Method and System for the improvement of the QoS support in de-centrally organized wireless networks. The IEEE 802.11 is enhanced so that the effects of contention of traffic classes with the same priority, that are competing for access to the transmission medium is reduced, thus guaranteeing QoS requirements. Stations that want to transmit, will begin transmission of an signal once they sense that the transmission medium is idle. This signal is transmitted for a number of time slots depending on the priority of the traffic class the station wants to transmit. Once this transmission is over the stations will again sense the medium. If it is busy the stations will resign from transmitting and wait till the next access cycle. If the medium is idle, then the stations will perform a random back-off and then begin to transmit. This random back-off is used to avoid any contention between stations that have the same traffic class priority as the station with the lowest random back-off will begin to transmit first.

Web-telco convergence comprising downloading script commands to user terminals

The present invention relates to methods, apparatus and systems for enabling an improved Web-Telco Convergence, in particular for telecommunication session oriented service. A Web-Telco Convergence Function (507) may identify user, interface relevant information in telecommunication protocol messages relating to a telecommunication session oriented service for a user and transmits the identified user interface relevant information to a Virtual Terminal Function (506). The Virtual Terminal Function may obtain web content based on the user interface relevant information and generate a user interface description. An address URL of the location of the user interface description may be transmitted to the Web-Telco Convergence Function (507) which may transmit the address URL to a user device (502). Keywords: mashup; scripts embedded in web pages containing telephonic API commands.

Procedimiento y dispositivo de comunicaciones para lograr una calidad de servicio relacionada con la distancia en un sistema de comunicaciones.

Procedimiento para transmitir datos en una red de comunicaciones, en el que los datos se transmiten en enlaces parciales (V1, V2, V3) desde una primera estación (S0) a través de al menos una segunda estación (S1) a al menos otra estación (S2, S3), asignándose a los enlaces parciales (V1, V2, V3) entre las estaciones (S0, S1, S2, S3) para la transmisión de datos distintas exigencias a la transmisión de datos, determinándose las exigencias a la transmisión de datos en función de una distancia geográfica de una estación retransmisora a la primera estación (S0), de tal forma que en cada caso las estaciones (S2) del enlace parcial (V3) que se encuentran geográficamente alejadas de la primera estación (S0) asignan para la respectiva retransmisión siguiente una exigencia a la transmisión de datos inferior a la de las estaciones (S1) que se encuentran geográficamente más próximas de la primera estación (S0).

Stovsuger

En støvsuger, særlig en gulvstøvsuger, har et modulært oppbygget hus innbefattende et stabilt, for ulike støvsugervarianter og som plastsprøytestøpedel utforrnet chassis (2) så vel som et variantspesifikt deksel (4) for chassiset (2). Dekselet (4) er utformet som et dyptrukket plastelement. I chassiset (2) er samtlige funksjonsbyggegrupper, eksempelvis for funksjonene inn/utkopling, ledningsspoling, integrert, og dekselet (4) innbefatter i hovedsaken bare betjeningselementer for disse funksjonsbyggegrupper.

Verfahren und funkstation zur datenübertragung in einem funk-kommunikationssystem

Erfindungsgemäss wird von einer ersten Funkstation (AP) ein Datenpaket (dp) zu mehreren zweiten Funkstationen (MT) in einem Übertragungskanal (BCH) gesendet, wobei das Datenpaket (dp) für eine erste Übertragung über die Funkschnittstelle mit einem ersten Fehlerschutz versehen wird. Nachfolgend wird von der ersten Funkstation (AP) das Datenpaket (dp) zumindest ein weiteres Mal zu den zweiten Funkstationen (MT) gesendet, wobei das Datenpaket (dp) für die weitere Übertragung über die Funkschnittstelle mit einem zweiten Fehlerschutz versehen wird, der gegenüber dem ersten Fehlerschutz eine erhöhte Redundanz aufweist.
