Method for routing data of a session initialized between a terminal and a server
A method for routing data of a session initialized between a terminal and a server, over a first network slice corresponding to a set of data-processing functions of a communication infrastructure, implemented by the terminal. This method includes receiving from the server at least one routing identifier determined as a function of at least one communication parameter of the session, configuring session information as a function of the at least one identifier received, and emitting to the server subsequent data routed over at least one second slice corresponding to the configured information.
1. A routing method for routing data of a 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, in a HyperText Transfer Protocol (HTTP), 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 routed over at least a second slice corresponding to the configured piece of session information.
2. The routing method as claimed in claim 1 , comprising ciphering the session by the terminal.
3. The routing method as claimed in claim 1 , comprising initializing the session 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 comprises a data element relating to a piece of Network Slice Selection Assistance Information (NSSAI) information.
5. The routing method as claimed in claim 1 , further comprising the terminal storing in memory the at least one routing identifier received based on the at least one communication parameter of the session.
6. The routing method according to claim 1 wherein the session is an HTTP session.
7. A determination method for determining at least one routing identifier of data of a session initialized between a terminal and an application server, over a first network slice corresponding to a set of functions for processing data of a communication infrastructure, implemented by the application server and comprising:
determining at least one routing identifier of the communication infrastructure based on at least one communication parameter of the session,
transmitting to the terminal, in a HyperText Transfer Protocol (HTTP) the at least one routing identifier determined, and
receiving from the terminal subsequent data routed over at least a second slice.
8. The determination method as claimed in claim 7 , where the at least one communication parameter relates to a transport layer of the session.
9. The determination method as claimed in claim 7 , where the at least one communication parameter relates to the Quick UDP Internet Connections (QUIC) protocol.
10. The determination method as claimed in claim 7 , where the at least one communication parameter relates to a protocol version of a transport layer.
11. The determination method as claimed in claim 7 , where the at least one routing identifier is transmitted in a data element of a transport protocol.
12. The determination method according to claim 7 wherein the session is an HTTP session.
13. A device for routing data of a session initialized between a terminal and a 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;
a transmitter; and
a processor configured to:
use the receiver to receive in a HyperText Transfer Protocol (HTTP) from the server at least one routing identifier determined on the basis of at least one communication parameter of the session,
configure a piece of session information based on the at least one routing identifier received, and
use the transmitter to transmit to the application server subsequent data routed over at least a second slice corresponding to the configured information.
14. The terminal comprising the device for routing as claimed in claim 13 .
15. The device according to claim 13 wherein the session is an HTTP session.
16. A device for determining at least one routing identifier of data of a session initialized between a terminal and an application server, over a first network slice corresponding to a set of functions for processing data of a communication infrastructure, implemented by the application server, wherein the device comprises:
a transmitter;
a receiver; and
a processor, configured to:
determine at least one routing identifier based on at least one communication parameter of the session,
use the transmitter to transmit in a HyperText Transfer Protocol (HTTP) to the terminal the at least one routing identifier determined, and
use the receiver to receive from the terminal subsequent data routed over at least a second slice.
17. The device according to claim 16 wherein the session is an HTTP session.
18. 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 for routing data of a 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 in a HyperText Transfer Protocol (HTTP) from the server at least one routing identifier determined based on at least one communication parameter of the session,
configure a piece of session information based on the at least one routing identifier received, and
transmit to the application server subsequent data routed over at least a second slice corresponding to the configured information.
19. The non-transitory computer-readable recording medium according to claim 18 wherein the session is an HTTP session.
20. 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 a 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 server to:
determine at least one routing identifier based on at least one communication parameter of the session,
transmit in a HyperText Transfer Protocol (HTTP) to the terminal the at least one routing identifier determined, and
receive from the terminal subsequent data routed over at least a second slice.
