Abstract

A method for recommending a communication stack formed of communication protocols, relating to a data session between a terminal and a first server to provide content in a network including a second server responsible for providing the content by delegation from the first server, the first server having detected incompatibility of the stack used by the terminal and having transmitted a redirection message including information relating to a recommendation of the stack to be used to obtain the content to the terminal. In the method, the second server receives, from the terminal, an acquisition request message; selects a stack to be recommended based on data relating to the communication network or to the received acquisition request message; transmits, to the terminal, a recommendation message including the recommended stack; and receives a message transmitted by the terminal, using the recommended stack, relating to the acquisition of the item of content.

First claim

The invention claimed is:

1. A method for recommending a communication stack composed of a plurality of communication protocols, which relates to a data session initiated between a terminal and a first server for the provision of a content in a communications network comprising a second server in charge of the provision of the content by delegation of the first server, the method being implemented by the second server and comprising:
receiving from the terminal a message requesting obtainment of the content,
selecting by the second server a stack to be recommended as a function of a data item relating to the communication network or to the obtainment request message received from the terminal,
sending to the terminal a recommendation message comprising the recommended stack, which includes a plurality of communication protocols,
receiving a message relating to obtainment of the content, transmitted by the terminal by using the selected recommended stack sent by the second server to the terminal.

2. The method for recommending a communication stack as claimed in claim 1 , furthermore comprising sending the first server an information message comprising the recommended stack.

3. The method for recommending a communication stack as claimed in claim 1 where the message requesting obtainment of the content comprises at least one communication stack.

4. The method for recommending a communication stack as claimed in claim 1 , where the recommended stack is transmitted in a field of the application layer of the recommendation message.

5. The method for recommending a communication stack as claimed in claim 1 , where the recommended stack is transmitted in a field of the transport layer of the recommendation message.

6. The method for recommending a communication stack as claimed in claim 1 , where the data item relating to the communication network is received from a management entity of the communication network.

7. A method for redirecting a content obtainment request relating to a data session initiated between a terminal and a first contend server in a communications network comprising a second server in charge of the provision of the content by delegation of the first content server, the method being implemented by the first content server and comprising:
receiving from the terminal a message requesting the content using a communication stack;
detecting an incompatibility of the communication stack used by the terminal to request the content from the first server with a communication parameter of the second server; and
sending the terminal a redirection comprising at least one communication stack, which includes a plurality of communication protocols that are compatible with the second server and are configured to be used by the terminal to obtain the content from the second server.

8. The redirection method as claimed in claim 7 , furthermore comprising a receiving from the terminal a message containing an information item of refusal of the recommended stack received.

9. The redirection method as claimed in claim 7 , where the communication parameter of the second server is a communication protocol.

10. A second server for recommending a communication stack, which includes a plurality of communication protocols relating to a data session initiated between a terminal and a first server for provision of a content in a communications network; comprising the second server, which is in charge of the provision of the content by delegation of the first server, wherein the second server comprises:
a receiver;
a sender;
a processor; and
a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the second server to perform acts comprising:
receiving through the receiver a message from the terminal
requesting obtainment of the content;
selecting by the second server a stack to be recommended as a function of a data item relating to the communication network or to the obtainment request message received from the terminal,
sending through the sender to the terminal a recommendation message comprising the recommended stack, which includes a plurality of communication protocols; and
receiving through the receiver a message relating to the obtainment of the content, transmitted by the terminal by using the selected recommended stack sent by the second server to the terminal.

11. A first server for redirecting a content obtainment request relating to a data session initiated between a terminal and the first server in a communications network comprising a second server in charge of provision of the content by delegation of the first server, wherein the first server comprises:
a receiver;
a sender;
a processor; and
a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the first server to perform acts comprising:
receiving through the receiver a message requesting the content from the terminal;
detecting an incompatibility of a stack used by the terminal with a communication parameter of the second server; and
sending through the sender to the terminal a redirection message comprising a plurality of communication protocols and an information item relating to a recommendation of a communication stack.

12. The first server as claimed in claim 11 , wherein the device is configured to receive from the terminal a message containing an information item of refusal of the recommended stack received.

13. A terminal requesting provision of a content in a communication network relating to a data session initiated between the terminal and a first content server in the communications network, which includes a second server in charge of provision of the content by delegation of the first content server, wherein the terminal comprises:
a receiver;
a sender;
a processor; and
a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the terminal to perform acts comprising:
sending through the sender to the second server a message requesting obtainment of the content, the message being sent using a communication stack;
receiving through the receiver a message sent by the second server of a recommendation indicating to the terminal to change the used communication stack and comprising a recommended stack including a plurality of communication protocols to be used to obtain the content; and
sending through the sender to the second server a message of obtainment of the content transmitted using the selected recommended stack sent by the second server.

14. A non-transitory computer-readable recording medium on which a computer program is recorded comprising instructions for implementing a method, when executed by a processor of a second server, of recommending a communication stack, which includes a plurality of communication protocols relating to a data session initiated between a terminal and a first server for provision of a content in a communications network comprising the second server, which is in charge of the provision of the content by delegation of the first server, wherein the instructions configure the second server to perform acts comprising:
receiving from the terminal a message requesting obtainment of the content;
selecting by the second server a stack to be recommended as a function of a data item relating to the communication network or to the obtainment request message received from the terminal;
sending to the terminal a recommendation message comprising the recommended stack, which includes a plurality of c
