Definitions
- the present invention relates to the field of telecommunication protocols and more particularly content display protocols for a remote site.
- WAP uses communication protocols that allow the transfer of content under conditions suitable for mobile devices.
- WAP uses the WML protocol for rendering remote content, WML is suitable for "simplified" documents and often limited screens on mobile devices.
- the state of the art includes the patent PT WO00 / 67448 describing a device and a method of user authentication which can be used in wireless electronic commerce transactions carried out using a mobile device.
- the micro-browser based on WML (WAP marking language) of the aforementioned device is associated with voice authentication on the network.
- WML WAP marking language
- This document discusses the fact that the transport protocol between a local WAP gateway and a local e-commerce server can be a WAP, HTTP or HTTPs / stack
- This patent describes the transport on a local network between a WML server and a WML application via a WAP gateway.
- the solution proposed in the prior art does not use the PPP layer between the gateway and the server, since it does not provide for access by an Internet access provider, but by a local network (Ethernet, ATM).
- Patent WO01 / 31852 relates to a microcontroller with access to the web providing both web server functions and generic control and monitoring functions. Integrated software for remote hardware control using the microcontroller combines a control application code and an HTTP server code.
- the physical communication unit includes a digital signal processor and a wireless access unit, thereby providing a wireless web access device.
- the processing of the physical wireless access layer is performed by the digital signal processor and the processing of the upper layer is performed on the microprocessor.
- This document describes the alternative use of WAP and HTTP, but not the transport of a document in WML format over Internet protocol layers.
- the invention relates in its most general sense to the use of WML in the standard environment for accessing a remote computer via the Internet and a wired provider. That is to say in using the HTTP protocols for the transfer of the information presented under WML, TCP for ensuring the end-to-end data transmission, IP the Internet protocol, PPP for the encapsulation of data between the equipment and the supplier 'Internet access.
- the WML document is sent by the server following an HTTP header, for which the 'Content-Type' field is set to value: ⁇ text / vnd. wap. wml 'or text / vnd. wap. wmlscript 'instead of the value: ⁇ text / html', usually used for transferring the information presented in HTML.
- WAP protocols can be used, for example WSP in place of HTTP, but IP and PPP remain used for connection across the Internet by means of a wired access provider.
- access to the Internet is not made directly by means of the switched telephone network but through a local network (using for example Ethernet, transmission by carrier currents, or even a local radio link) and a connection gateway between this local network and the switched telephone network.
- a local network using for example Ethernet, transmission by carrier currents, or even a local radio link
- a connection gateway between this local network and the switched telephone network.
- connection to the Internet is made by a broadband connection (using for example ADSL or cable).
- the invention also relates to an electronic component for exchanging and displaying remote information, characterized in that it comprises a monolithic integrated circuit integrating a DSP type microcomputer, and read and write memories, as well as a input / output interface circuit, read only memory containing a communication stack comprising the lower layers of the Internet stack, and the upper layer or layers of the WAP stack.
- said communication stack comprises an information transfer layer formed by an HTTP layer, and a rendering layer which is the WML layer.
- said communication stack comprises an information transfer layer formed by a WSP layer, and a rendering layer which is the WML layer.
- the read-only memory contains a communication stack comprising the lower layers of the Internet stack, and the upper layer or layers of the WAP stack.
- the present invention also relates to a system comprising a WML document server and client equipment, characterized in that the client equipment comprises a component comprising a monolithic integrated circuit integrating a DSP type microcomputer, and read and write memories, as well as a input / output interface circuit, the read-only memory containing a communication stack comprising the lower layers of the Internet stack, and the upper layer or layers of the WAP stack.
- the client equipment comprises a component comprising a monolithic integrated circuit integrating a DSP type microcomputer, and read and write memories, as well as a input / output interface circuit, the read-only memory containing a communication stack comprising the lower layers of the Internet stack, and the upper layer or layers of the WAP stack.
- FIGS. 1 and 2 represent schematic views of the communication protocol stacks according to the state of the technique
- FIG. 3 represents the schematic view of the communication protocol stacks according to the invention
- FIG. 4 represents a schematic view of the architecture of a connectable item of equipment according to the invention.
- FIG. 1 An "Internet" communication stack is shown, represented in FIG. 1.
- This stack comprises first of all a material layer (1): for example the ETHERNET cable, the modem (Modulator-demodulator), the optical fiber, the radio link, ...
- a material layer (1) for example the ETHERNET cable, the modem (Modulator-demodulator), the optical fiber, the radio link, ...
- the next layer is the Internet Protocol layer (2). It ensures the transport of packages.
- the UDP layer (3) is shown only for the record. It has no impact in the context of the invention.
- the TCP layer (4) ensures the shaping of the packets: cutting and re-shaping of the packets and establishment of a connection.
- the HTTP layer (5) ensures the transfer of information.
- the HTML layer (6) renders the document.
- the Internet stack is used for the presentation of rich information (Rich content), displayed on monitors allowing complex displays.
- WAP Another protocol stack known as WAP is known in the prior art, more suitable for wireless communications and equipment comprising screens with reduced display capacities.
- This stack comprises a WSP layer (7) for transferring information, ensuring the same role as the HTTP layer (5), and a WML layer (8) ensuring the rendering of the document on low level screens.
- the invention relates to a new protocol stack, shown in FIG. 3.
- This stack includes the bottom layers (1, 2, 4 and possibly 3) of the Internet stack, and the top layer (s) of the WAP stack.
- It includes a file transfer layer (10) which can be an HTTP layer or a WSP layer, and a rendering layer which is the WML layer (11).
- the communication between the WML layer (11) and the file transfer layer (10) HTTP is unusual and is made possible in the invention by the insertion of specific texts in the documents.
- FIG. 4 represents a schematic view of a connectable device according to the invention.
- the equipment comprises a component (15) formed by a monolithic integrated circuit integrating a DSP type microcomputer (20) and random access memories
- the battery shown in FIG. 3 is loaded in read-only memory (22), and can be installed in random access memory (21) so that it can be executed by the microcomputer (20).
- the read-only memory (22) also includes a modem application, executable by the microcomputer (20). It also includes a WML browser.
- the input-output circuit (23) provides the interface with the peripherals such as a keyboard (24), a screen (25), as well as the network (26).
- This component makes it possible to bring advanced communication functions to various equipment such as a photocopier, a camera or shooting equipment, a meter that can be read remotely, etc. These communication functions allow documents available on a remote station, connected to the network, to be viewed on equipment fitted with such a circuit.
