Configurable mapping of quality of service classes

A method, comprising:

• detecting a requested quality of service level of a new data flow or an existing data flow at a user equipment, an indication of the requested quality of service level embedded in a data flow packet;
• retrieving from a table, at the user equipment, a parameter linked to the requested quality of service level, the parameter is linked to the requested quality of service for a radio link layer;
• marking an uplink data packet using a quality of service marking as detected in a downlink data packet received by the user equipment;
• and
• sending the uplink data packet to a network entity.

An apparatus comprising:

• at least one memory comprising computer program code;
• at least one processor;
• wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
• detect a requested quality of service level at a new data flow or an existing data flow at a network entity, an indication of the requested quality of service level embedded in a data flow packet;
• retrieve from a table a parameter linked to the requested quality of service level;
• and
• use the parameter to create a new radio link layer processing instance or to update an existing radio link layer processing instance at the network entity.
