Method for routing data of a session initialized between a terminal and a server

1. A routing method for routing data of an end-to-end session initialized between a terminal and an application server, over a first network slice corresponding to a set of data processing functions of a communication infrastructure, implemented by the terminal, and comprising:

receiving from the application server at least one routing identifier determined based on at least one communication parameter of the session,

configuring a piece of session information based on the at least one routing identifier received, and

transmitting to the application server subsequent data of the end-to-end session routed over at least a second slice corresponding to the configured piece of session information.

2. The routing method as claimed in claim 1 , where the end-to-end session is ciphered by the terminal and deciphered by the application server.

3. The routing method as claimed in claim 1 , where the end-to-end session is initialized by the terminal by configuring a default piece of session information.

4. The routing method as claimed in claim 1 , where the piece of session information is a data element relating to a piece of NSSAI information.

5. The routing method as claimed in claim 1 , further comprising the terminal storing in memory the at least one identifier received based on the communication parameters of the end-to-end session.

6. A determination method for determining at least one routing identifier of data of an end-to-end session initialized between a terminal and an application server, over a first network slice corresponding to a set of functions for processing the data of a communication infrastructure, implemented by the application server, and comprising:

determining at least one routing identifier based on at least one communication parameter of the end-to-end session,

transmitting to the terminal the at least one identifier determined, and

receiving from the terminal subsequent data of the end-to-end session routed over at least a second slice.

7. The determination method as claimed in claim 6 , where the at least one parameter relates to a transport layer of the end-to-end session.

8. The determination method as claimed in claim 6 , where the at least one parameter relates to a Quick User Datagram Protocol (UDP) Internet Connections (QUIC) protocol.

9. The determination method as claimed in claim 6 , where the at least one parameter relates to a protocol version of the transport layer.

10. The determination method as claimed in claim 6 , where the at least one identifier is transmitted in a data element of a transport protocol.

11. A device for routing data of an end-to-end session initialized between a terminal and an application server, over a first network slice corresponding to a set of data processing functions of a communication infrastructure, implemented by the terminal,

wherein the device comprises:

a receiver, configured to receive from the application server at least one routing identifier determined based on at least one communication parameter of the end-to-end session,

a processor, configured to configure a piece of session information on the basis of the at least one identifier received, and

a transmitter, configured to transmit to the application server subsequent data of the end-to-end session routed over at least a second slice corresponding to the configured piece of session information.

12. A device for determining at least one routing identifier of data of an end-to-end session initialized between a terminal and an application server, over a first network slice corresponding to a set of functions for processing the data of a communication infrastructure, implemented by the application server, wherein the device comprises:

a processor, configured to determine at least one routing identifier determined based on at least one communication parameter of the end-to-end session,

a transmitter, configured to transmit to the terminal the at least one identifier determined, and a receiver, configured to receive from the terminal subsequent data of the end-to-end session routed over at least a second slice.

13. A non-transitory computer-readable recording medium comprising a computer program recorded thereon, the computer program comprising instructions for implementing a routing method when the instructions are executed by a processor of a terminal, the routing method routing data of an end-to-end session initialized between the terminal and an application server, over a first network slice corresponding to a set of data processing functions of a communication infrastructure,

wherein the instructions configure the terminal to:

receive from the application server at least one routing identifier determined based on at least one communication parameter of the end-to-end session,

configure a piece of session information based on the at least one identifier received, and

transmit to the application server subsequent data of the end-to-end session routed over at least a second slice corresponding to the configured piece of session information.

14. A non-transitory computer-readable recording medium comprising a computer program recorded thereon, the computer program comprising instructions for implementing a determination method when the instructions are executed by a processor of an application server, the determination method for determining at least one routing identifier of data of an end-to-end session initialized between a terminal and the application server, over a first network slice corresponding to a set of functions for processing the data of a communication infrastructure,

wherein the instructions configure the application server to:

determine at least one routing identifier based on at least one communication parameter of the end-to-end session,

transmit to the terminal the at least one identifier determined, and

receive from the terminal subsequent data of the end-to-end session routed over at least a second slice.
