Abstract

The network system comprises a local server connected to radio access points allowing access by local terminals in radio mode (RLAN). The network system generates access authorisations which can be printed on paper and allows the verification of authorisations by one of the connected terminals. The network system comprises a local server connected to radio access points allowing access by local terminals in radio mode (RLAN). A data server containing a data base, called the visitor database, automatically generates either intrinsically or with the aid of a program in a connected server, a code of at least 4 characters, called the complex personal code. A data routing system is able to point data towards the Internet. The network system generates access authorisations which can be printed on paper and allows the verification of authorisations by one of the connected terminals. The system uses four possible levels of accreditation for interaction with the visitor database, each of the levels permitting a specific action with this database.

  The purpose of the present invention is to facilitate the exchange of information between users of portable written communication systems in a nomadic situation and a data server of the Web type containing information

  essential on a place open to the public.

  A typical application of this invention is the direct linking of visitors traveling in a place open to the public with applications

  stationary computers in this place.

  This invention relates more particularly to a novel process which relies on the implementation of new techniques of the world of telecommunications and computer science: - An information server which contains the local information of the place open to the public (SSV); - A local network in radio technology (quoted RLAN) completed by a wired technology; - Open network access to the outside world via Internet Protocol; - Portable terminals (or not) connected by the network to the server

(ISS);

  The originality of this method lies partly in that the information server is preformed to accept information according to precise fields, these fields being able to be filled directly by a person having personalized access to them. pages in writing mode, and secondly in that access to read information is via the RLAN which directs the communications on the home page, the home page presents emblee

  structured information allowing a selection of groups of information.

  Hypertext links can enrich the informational content and direct the visitor towards specific programs of demonstration by

  example via the local fllaire or radio network or even via the Internet.

  Finally, a selection of some groups of information among all the groups followed by a recording of this selection, makes it possible to save the essential information, the hypertext links afferent and to crush them according to

variable parameters.

  A typical case of use of this process is the establishment of a virtual showroom in entrance and accompanying a real showroom,

2 2840136

  consists of demonstration stands. The selection of some stands on the server makes it possible to define the meaning (optimization of the displacements) and the contents

  visiting the salon for a visitor.

  At present, the only method for a salon visitor to dynamically search for exhibition exhibitor information on-site is the paper directory. This information is limited and can not be sorted according to multiple criteria. Moreover, the data printed on a directory often need to be rewritten on a parallel support to be properly exploited on the spot. Finally, no solution allows sorting

  selected information and their exploitation on the spot.

  The invention eliminates all these major drawbacks by setting up a

  method based on portable communication systems.

  In this case, the visitors of the show establish their first search on the server of data open to the public (SSV), where the server was previously

  filled with information by the exhibiting companies according to the method described here.

  Inventio n can be described as com me su it.

  The information server (SSV) is constituted around a system of type

  Web server accessible via the Internet or locally.

  A method of making the invention in a place open to the public is

described in Figure 1.

  The information server (SSV) is connected to a data routing system of type << Router >>, denomme (RD). This data routing system (RD) allows the connection between this server (SSV) and a Radio Server (SR) that allows

  manage the radio access points located inside a public place.

  In a variant of the invention, the features of this Radio Server integrated into the Information Server (SSV) or into the radio access points, or both by part, thus allowing the deletion to said Radio Server. The data routing system (RD) is connected to the Internet-type external network, allowing, if necessary, routing the data to this external port. The Data Routing System (RD) can also be provided (internally)

3 2840136

  or on a separate system) of a firewall system, allowing security isolation between the outside world in Internet Protocol and the internal world of the Internet.

Place open to the public.

  In a variant of the invention, the information server (SSV) is located outside the enclosure of the location open to the public: in this case the data routing system (RD) needle useful data to the server. information (SSV) through the Internet external network, and the whole process described below can

apply in the same way.

  A system of access points in Radio LAN technology is connected to the Radio Serveur (SR), thus allowing the connection to this remote terminal server equipped with radio card of the same technology Radio LAN. However these same terminals can also be connected by wired network (LAN network),

  which wired network is interconnected to the Radio Server (SR).

  All this system architecture is therefore accessible by portable computers (PDA, PC, ...) terminals equipped, if necessary, radio card in the RLAN communication standard set up or wired LAN card. Three levels of information access control associated with the information server (SSV): The N1 level allows users to fire the pages of the server according to their navigation. Wind users prompts to decline their identity and password

  to have permission to "surf" on this server.

  Level N2 allows staff who wish to enter information into the server inside the fields reserved for this purpose to do so. These staff are invited to present a "log-in" and then a password to access the writing mode of this server, and only in the fields

reserved for this purpose.

  Level N3 is the highest level of server access (SSV). It allows the server administrator to control the content and visits of the site, as well as to deduce usage statistics. The same type of access control is

  uses: << log-in >> and password.

  At first, the administrator of the Web server will elaborate the structure

4 2840136

basic information content.

  Examples of information content are shown in Figures 2 to 6.

  It consists for example of two cover pages, presenting more particularly: 1 ERE PAGE OF GUARD (fig 2): - The "log-in" and the password; - Referral to the server (SSV) itself or other applications; 2 EME PAGE OF GUARD (Fig. 3): - The names of the presentations that follow (preformatees); - A search engine based on a number of key words; These cover pages may, in another version of the invention, be reduced

  or on the contrary extended with more or less fields of information.

  Choosing a presentation name automatically leads to the first of the two preformatted pages: 1 PREFERRED PAGE (Fig. 4): Presentation of the person (company, ..) and presentation of the first specific information field (eg 1st product / service);

  - List of keywords to feed the search engine.

  2 EME PREFORMATTE PAGE (Fig. 5): - Presentation of three other specific information fields (for example: 2nd and 3rd produiVservice and a promotion)

- Useful URL links.

  - Selection of the person (i.e. of the two preformed pages)

I SELECTION PAGE (Fig. 6).

  - Presentation in table format of the selected staff and their main characteristics: this page is created for each user. These preformed and selection pages may, in another version of the invention, be reduced or extended with more or fewer fields.

information.

  Pages 1 and 2 preformatees wind reproduced as many times as necessary

  for as many different descriptions, and by so many different staff

2840136

  as decided by the web server administrator (SSV). Each group of two

  pages reproduces an identical format, with different content.

  The development of such a Web server uses common computer languages

  programming a web server (Java language, JEE, ...).

  As a second step, staff who want to set up Web server (SSV) content in preformed zones

  the server administrator a "log-in" and N2-level password associates.

  This password will give them direct access to the two preformed pages dedicated. The person can then enter, in each of the pre-formatted zones, the data he wishes, according to the expected format. The length of the message must be respected as well as the graphics and the format of the text. The text editor is from

  common type and leaves very little freedom in the graphics.

  Pictograms, sketches or photos can be added to the text

  in a precise format. This attachment file can be deflni in bitmap format.

  Similarly, hypertext links can be introduced at will text, allowing

  to specify an associated URL.

  Figure 3 gives an example of the type of content that can fit into such a

data presentation framework.

  Entering keywords in the box provided for this purpose causes,

  the recording, putting in memory of the couple keyword / name of the person.

  It is this memory that is the basis of the search engine of the web server

(SSV).

  In a third time, and once the web server (SSV) complete with all

  descriptions that are necessary for the given application, the users of this

server can then exploit it.

  This operation uses the following elements: - Portable PDA or laptop terminal; - Local Radio Network or (RLAN); - Radio card residing on the portable terminal and compatible with the RLAN. Users equipped with such terminals can then move to the place open to the public and have access, in a situation called "nomadism" to

6 2840136

seweur applications.

  This access is done directly on the first page of guard of seweur. Users must then enter their N1 level name and password

  associates to be able to enter on the second page of guard of seweur (SSV).

  This second cover page provides access to other information pages (preformatted and filled pages) directly by choosing the name of the person. In this case the user can either select the name of the person chosen from the list set up by the administrator of the Web site, or enter the name of the person directly on the space provided for this purpose (cf. Fig. 3). This selection of the name of the person results in the use of the first of the two preferred pages devoted to

  the person and the related information (Figures 4 and 5).

  In a second case of selecting the second cover page, the user can choose a theme that appears in the search engine. The selection of a research theme brings to the screen the names of all the personnel who are referred to under this theme. The search engine then performs direct sorting on the person's keyword-name, and for each key word

  request returns the complete list of associated staff names.

  The user can then select a person name, which leads him directly to the first preformate filled page of the person in question. The user then becomes aware of the informational content of these pre-formatted pages (Figures 4 and 5). From the second preformatee page (fig.5), hypertext links can allow the user to be sent back to an Internet address (URL) outside the server domain (SSV). In this case, the sewer directs the connection to the external port connected to the Internet or to the

  seweur (SR) if the requested address is a known address of the local network.

  If the user wishes it, it is possible for him to make the selection of the information on the person who is presented to him. In this case, he must perform

  the choice corresponds to the registration in the personal list (FIG.

  This action has the consequence of enriching the PERSONAL SELECTION PAGE (fig.6) which is created for each user and can only be consulted by the user who has validated the password of level N1 corresponding to

his "log-in".

  This page presents, for example, in tabular form and for all

7 2840136

  personnel who have been registered in the personal list, the identity of the personnel, their local co-ordinates, their regal coordinates, the key words,

the titles of the Products / Services.

  The user can then, in this page, choose to sort this list either by the name of the staff, or by the addresses (local or regales), or by the keywords,

either by the Products / Services.

  This table (sorted or not) is also exportable to the local memory of the user's laptop, in a common software format (spreadsheet,

  word processing or HTML format).

  The file is then sent by the server (SSV) to the router (RD) that sends it

  to the requesting terminal via the network bits.

  This list is then searchable at any time by the user, and in particular when

  its mobility in the place open to the public.
