Abstract

The present invention relates to a process for managing context data (40) for a multilateral and multimode operation, using several software configurations allowing surfing on at least one network in order to access to a content provider service, representing information which is either specific to a content provision session via computer communication, through at least one information network (1), between at least one digital data processing device, called client terminal (30 to 35), and at least one content provider information system (2), or specific to the user of said client terminal(s), or specific to a combination of these elements, this context data (40) being stored outside the content provider information system(s) (2) and at the request of said provider system(s) (2), characterised in that it comprises at least one step wherein this context data is stored in storage means by one or more computer agents, called context proxies (4), in storage means independent of the client terminal(s) and of the software configuration concerned used, and accessible from at least one information or electronic system managing the information network (1).

3. Process according to claim 1, characterised in that it comprises at least one operation of response by the content provider system to the client terminal by the sending of data representing a response, this response operation including the following steps:

the receipt, by at least one context proxy agent, of data associated with a response by the content provider system to the client terminal, this response including at least one request for storage of context data, this data having to be stored outside said content provider system and at its request;

4. Process according to claim 3, characterised in that the storage of the context data includes the storage of a client identifier or a session identifier.

5. Process according to claim 3, characterised in that the response operation from the content provider system to the client terminal additionally includes a step wherein the client terminal is asked for an authorisation to store context data.

6. Process according to claim 1, characterised in that it includes at least one communication step where a context proxy agent communicates, directly or indirectly, on the one hand with the content provider system via the information network, and on the other hand with the client terminal or with a mode gateway allowing the information network to communicate with this client terminal according to a given communication mode different from the one used by the information network.

7. Process according to claim 1, characterised in that it includes at least one communication step where a first context proxy agent communicates on the one hand with a first mode gateway allowing communication with this client terminal according to a first given communication mode, and on the other hand with a second context proxy agent communicating with said client terminal, this second context proxy agent communicating with this client terminal either via the information network or via a second mode gateway allowing communication between the network and this client terminal according to a second given communication mode.

8. Process according to claim 7, characterised in that the content provision session via computer communication includes a first session part, obtained by a communication according to the first communication mode, combined with a second session part, obtained via a communication according to the second communication mode, the process including at least one step of storage or reading context data representing information that can be used by the context proxy agent or by the content provider information system in order to associate these two session parts.

9. Process according to claim 1, characterised in that at least one communication step between the content provider information system and the context proxy agent is carried out by at least one protocol compatible with the TCP/IP protocol or the HTTP protocol.

10. Process according to claim 1, characterised in that the client terminal includes a digital terminal or a cellular telephone, at least one communication step between the client terminal and the network being carried out by wireless connection according to the GSM standard, or the DCS standard or the GPRS standard, or the Airport standard, or the Bluetooth standard or the ISO 802.11 standard (trademarks), or a variant or development of these standards.

11. Process according to claim 1, characterised in that the client terminal includes a digital terminal or a cellular or wired telephone, at least one communication step between the client terminal and the network being carried out by a protocol compatible with the,WAP protocol, or a protocol using the VoiceXML language, or a variant or development of these protocols.

12. Process according to claim 1, characterised in that the network allows computer communication between the content provider system and the client terminal by using the Internet network or a network of the Intranet type.

13. Process according to claim 1, characterised in that the context data transmitted or the context data received by the content provider information system is organised in a format compatible with the “

cookies”
