The present invention also relates to a method for accessing digital data sources of information by users, in particular when they are transported by public transport, by means of a system comprising several communicating devices which are each capable of broadcasting at least one of said sources of digital data data, and - at least one mobile peripheral user equipment, which method comprises the following succession of operations: - the search and collection of the communicating device (s) present in the perimeter of radioelectric radiocommunication means of said peripheral equipment, - identification and filtration, among said collected communicating devices, of those transmitting said sources of digital information data, - generation of a list of data sources digital information available, - the display of said list on the screen of said equipment peripheral device; - selection by the user of one of said sources of digital information data, and - establishment of a radio connection via radio communication means equipping said peripheral equipment and said corresponding communicating device, for access to the digital data source of selected information. The invention is further illustrated, without being limited in any way, by the following description of a particular embodiment applied to a public transport network, this in relation to the appended FIGS. 1 to 3 schematically showing the main steps of the method for access to information. In order to accompany the user when traveling or traveling on a transport network, the method and the system according to the invention rely on the provision of a set of data sources at the strategic locations of this network. digital information providing individualized access to localized information. This local information is advantageously related to the information needs expressed by the user; it is also a function of the location of the source within the network and the organization of flows. Preferably, it is considered as the strategic location of the network, any entry point of the network (stop, wharf, interchange, station, bus shelter, etc.) and vehicles component (bus, bus, train, tram, taxi , boat, etc.). Each of these strategic locations is therefore equipped with a communicating device 1a comprising at least (not shown): - a central processing unit (microprocessor type), - local radio radiocommunication means (Wifi, Bluetooth, etc.). memory means (for example RAM), containing at least one of the sources of digital information data to be transmitted, own signaling means, in particular ensuring a visual reference of the location and identification of the system data source. Each of these communicating devices thus forms a point or an access terminal, allowing a connection via a wireless link; these communicating devices together form, from the point of view of the user, a wireless information network. The information conveyed by each of these sources is advantageously textual. This type of information has the particularity of being able to adapt to the users having a visual handicap, being by its nature possibly recoverable without difficulties in sound form via a conventional screen vocalization software in itself. The information conveyed by each digital data source is moreover advantageously of the contextual type, and its purpose is to enable the user to find and orient himself from a temporal and spatial point of view within the network. In practice, the information includes, for example, the following elements: - transit times or waiting times for vehicles at a fixed point in the network, - business messaging (general and disturbance messages), - connections, - the next stops of a line, - the arrival time of a vehicle at its next stops, - the timetable of the lines, etc. Access to sources of information is made through any mobile electronic equipment 2 belonging to the user, which is conventional in itself (mobile phone, personal assistant commonly referred to as a PDA, etc.). This equipment 2 has for this at least (not shown) - a central processing unit, - radio local radio communication means (Bluetooth, Wifi, etc.), - a display screen, - memory means, hosting at least one software application described in more detail below. The discovery and access to information sources are driven by the application present on the mobile device of the user and on the initiative of the latter (in particular to provide an appropriate response to issues of particularly high power consumption of this type of device). This software application (or application software or computer program), suitably designed and programmed, includes and ensures in particular the following functional means: - means for searching and collecting the communicating device or devices present in the perimeter of the means radioelectric radiocommunication device of said peripheral equipment; means for identifying and filtering, among said collected communicating devices, those transmitting said sources of digital data data; means for generating the list of available digital data information sources; means for displaying said list on the screen of said peripheral equipment; means for selecting one of said sources of digital information data; and means for establishing a radio connection via the radiocommunication means of said equipment; said communicating device co corresponding for the access by the user to said selected digital data source information. In practice and initially, the application will seek and collect the communicating devices 1 present in the radio perimeter (preferably in transmission) of the user's device 2, by means of these activated radiocommunication means ( figure 1). This detection is also a function of the coverage area (in particular in transmission) of the communicating devices 1. This scanning operation completed and from the result of this scanning, the application will identify and filter, among the detected communicating devices 1, those 1 having one or more sources of information 3 specific to the use sought by the user (Figure 2). This identification step is advantageously made possible by the use of a range of identifiers dedicated to the wireless network of interest, which will enable the application to distinguish the communicating devices 1a of this network from the set of communicating devices 1 detected within the radio perimeter of the device 2 of the user. For example, this identifier range is of the GUID or Globally Unique IDentifier numeric identifier type. More precisely, each local information source 3 is advantageously characterized by an identifier belonging to a specific identification range as well as by a label enabling the user to quickly identify its nature: for example, a fixed element (stop, etc. .) or mobile (Bus, etc.) of the public transport network, as well as its location in the organization of the transport network flows through the line and the destination to which it is attached (eg Center Stop City Line 2 Town Hall or Bus Line 2 Town Hall).

Once this discovery and filtering finalized, the application provided to the user, through the screen of his device 2, the list of local information sources 3 available and accessible, which he can access at this location and at this moment.

This list contains for this the wording of each of the sources 3, as described above. This mode of designation will allow the user to simply identify the available sources 3 and choose the one that best corresponds to the current stage of its path on the network.

The user selects the source of information that interests him; then through the radio communication means of the device 2, the application allows the reception of information transmitted by the connection / radio link with this source 3 (Figure 3). As represented in FIG. 3, the user here selects one of the two sources 3 of a communicating device 1 a. The dialogue set up between the two entities 1 a and 2 (represented diagrammatically in FIG. 3) is of the client / server type: the information source 3 serving as a server, and the user through its peripheral 2 serving as the customer.

The exchanges are dynamically organized around two methods: the so-called push method (the server sends the information to the client) and the so-called pull method (the client will look for the information on the server). These methods make it possible to adapt to the nature and the importance of the information, the speed of the radio communication channels, as well as the load of use of the same source by a set of users. The architecture and the organization of the exchanges between the two entities la, 2 offer a fluidity, a flexibility and a robustness in the transmission and the update of the information, whose peculiarity is its strong dimension real-time while this by guaranteeing a quality of service.

In practice and as an example, in pull mode, a simple request is sent by the device of the user 2 towards the communicating device 1a, without returning information from the client to the server. This allows in particular to avoid the sending of personal information, and also to limit the power consumption by the device of the user 2. From the point of view of the user, the communication is thus of the one-way type, it that is, server to client. The user, through the application and its navigation interface function, accesses the information made available by the source 3 to which it is attached. Information, as such, is advantageously structured in an organized and hierarchical sequence of screens structuring the textual information and promoting its accessibility by the user according to different levels of requirements such as its nature, its importance, its time dimension real or its supposed frequency of consultation.

The user has the ability to navigate within this sequence and tree of screens through the interaction mechanism offered by its device 2 (keyboard, keys, stylus ...). The connection between these two entities 1 a and 2, and therefore the communication, is maintained during the period when each entity detects the presence of the other in its radio proximity zone. The user can also interrupt at any time its connection with the source 3, in order to be able to adapt the information it needs to move it via another source. In general, the method and the system according to the invention make it possible to inform users in a localized and individualized manner, for example during their travels on a transport network whatever the size, nature and type. . The invention also allows individuals to quickly and simply access information that is advantageously located geographically and individualized among a multiplicity of digital data sources of information.
