Method for transmitting a data stream in a communication network, method for processing a data stream, method for controlling the processing of a data stream, and corresponding devices, terminal apparatus, execution entity, control entity, system and computer programs

A method for controlling processing of a data stream in a communication network, said communication network being divided into a plurality of network slices, said data stream having been transmitted by a terminal apparatus and received by an execution entity of said network in a network slice of said plurality, wherein said method is implemented by a control entity of said network, said control entity being configured to control implementation of a policy for processing the data streams routed in said network, and wherein said method comprises:

• receiving from the execution entity a notification of a priority indicator associated with said received data stream;
• obtaining a level of resources available in the network slice;
• deciding on at least one action for processing said stream at least according to the received priority indicator and the level of available resources, said processing action belonging to a group comprising at least one first action to let the data stream pass in said network slice intended to be implemented when the level of available network resources is sufficient for routing the data stream according to the priority indicator and a second action to block the data stream in said network slice intended to be implemented when the level of available network resources is insufficient;
• and
• sending a response to said execution entity, said response comprising said processing action.

A device for transmitting a data stream by a software application running on a terminal apparatus, in a communication network to which said terminal is connected, said network being divided into a plurality of network slices, wherein said device comprises:

• at least one processor;
• and
• at least one non-transitory computer readable medium comprising instructions stored thereon which when executed by the at least one processor configure the device to implement at the terminal apparatus:

• obtaining a type of said stream, said type belonging to a group comprising at least one first type and a second type of stream;
• inserting a priority indicator associated with the type of stream into the data stream, the priority indicator belonging to a group comprising at least one first indicator associated with the first type of stream and a second indicator associated with the second type of stream, the first priority indicator and the second priority indicator having different values;
• and
• transmitting the data stream comprising the priority indicator in the selected network slice.

A device for processing a data stream in a communication network, said network being divided into a plurality of network slices, said data stream having been received in a said network slice of said plurality, from a software application running on a terminal apparatus connected to said network, wherein the device comprises:

• at least one processor;
• and
• at least one non-transitory computer readable medium comprising instructions stored thereon which when executed by the at least one processor configure the device to implement at an execution entity of the network:
• detecting a priority indicator of said stream in said data stream;
• evaluating a level of resources available in the network slice;
• executing at least one action for processing said data stream at least according to said priority indicator and the level of network resources available in said network slice, said processing action belonging to a group comprising at least one first action to let the data stream pass in said network slice, when the level of available resources is sufficient, and a second action to block the data stream in said network slice, intended to be implemented when the level of available network resources is insufficient.
