Method and system for wireless distribution of local information
First Claim
1. A system for locally providing information comprising:
- a portable device including a display and means for connecting to a local network, anda local information server connected to or arranged to establish said local network, the portable device and the local information server being capable of connecting to each other in the local network, whereinthe local information server is arranged for periodically emitting signals in the local network indicating the existence of the local information server,the portable device is arranged to listen to the signals and when the signals are detected, to connect to the local information server in the local network, and to receive from the local information server address information of how to access available services, each of said available services including a user part and an information part with information of that service,the portable device is arranged, after having received the address information, to connect, via the local network, to a storage information server connected in a general service network using said address information and to obtain from the storage information server said information of the available services,the portable device is arranged to graphically show on its display symbols derived from said obtained information, each symbol being associated with an individual available service, andthe portable device is arranged to obtain, after a user of the portable device has marked or indicated one of the symbols shown on the display, from the general service network, via the local network, the user part of the service, with which the symbol is associated, the user part comprising an executable program, and to store the user part in a memory of the portable device and to automatically install and start executing the executable program of the user part,wherein the portable device is arranged to continue, after detecting the signals emitted by a local information server and connecting thereto, to listen to the signals emitted by the local information server, and to automatically remove from the display, after a predetermined time period elapsed from a last time when the signals were detected, the symbols associated with the services available in the information previously obtained from the storage information server, and to automatically remove from the memory the user part stored therein.

Abstract
In a system, called an application manager, portable devices 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 through some base unit. 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, 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, it is then 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 does not require communication or information relevant to the current location of the user, such as timetable information for trains and air flights.
