Title
(EN) METHOD AND SYSTEM FOR WIRELESS DISTRIBUTION OF LOCAL INFORMATION
(FR) PROCEDE ET SYSTEME DE RADIODISTRIBUTION DE DONNEES LOCALES
Abstract
(EN) In a system, called an application meneger, portable devices (1) can be connected in various kinds of local area networks (LANs). In the portable devices local browsers are run to find services by listening in the local area network to messages broadcast from a local information server (5) through some base unit (3). The local information server registers local services and provides, on automatic requests from the local browsers, address information of the local services. The address information is used by a local browser to obtain, through the Internet, general information of the services from an HTTP server (9), that contains information of applications, such as graphical information including icon files and short descriptions of the applications. After receiving the general information symbols of available services are shown on the display of the portable device. The user can then by a single click access a service and then the local browser automatically downloads the user part of the application the symbol of which has been clicked and starts to execute the program of the application, the executing generally not requiring communication or information relevant to the current location of the user, such as timetable information for trains and air flights.
(FR) Dans un système, appelé gestionnaire d'applications, des dispositifs portables (1) peuvent être connectés dans différents types de réseaux locaux d'entreprises (LANs). Dans ces dispositifs portables, on utilise des outils de survol locaux pour trouver des services en écoutant dans le réseau local d'entreprise des messages diffusés depuis un serveur d'informations locales (5) par une unité de base (3). Le serveur d'informations locales enregistre les services locaux et fournit, sur des demandes automatiques émanant des outils locaux de survol, des données adresses des services locaux. Les données adresses sont utilisées par un outil de survol local pour obtenir, via l'Internet, des informations générales des services d'un serveur HTTP (9) qui contient des informations d'applications, telles que des informations graphiques comportant des fichiers iconiques et de brèves descriptions des applications. A réception des données générales, des symboles de services disponibles sont présentés à l'écran du dispositif portable. Ensuite, l'utilisateur peut par simple click accéder à un service puis l'outil de survol local télécharge automatiquement la partie utilisateur de l'application dont le symbole a été cliqué et démarre pour exécuter le programme de l'application, l'exécution n'exigeant généralement ni communication ni information pertinente pour l'actuel emplacement de l'utilisateur, telle qu'une information d'horaires de trains et de vols.
