Abstract

Methods of transmitting information relating to a quality of service are shown, which information is to be transmitted in at least one direction between a first device 30 and a second device 20. A first method comprises at least at one of the devices 20, 30 assembling a protocol message containing information other than the information relating to a quality of service and attaching the quality of service related information to the protocol message. A second method comprises forming the information relating to a quality of service inside at least one of a header field and an attribute of a protocol message. The disclosure relates equally to corresponding software codes, devices 20, 30, network elements and systems.

attaching said information relating to a quality of service to said protocol message.

12. A device comprising:

an assembling component for assembling a protocol message containing information other than information relating to a quality of service, and for attaching information relating to a quality of service to said message, which quality of service information is to be transmitted to another device; and

a transmitting component for transmitting a protocol message assembled by said assembling component to said other device.

13. A network element of a network comprising:

an assembling component for assembling a protocol message containing information other than information relating to a quality of service, and for attaching information relating to a quality of service to said message, which quality of service information is to be transmitted to a device accessing said network; and

a transmitting component for transmitting a protocol message assembled by said assembling component to said device.

14. A system comprising at least a first device and a second device,

said first device comprising an assembling component for assembling a protocol message containing information other than information relating to a quality of service, and for attaching information relating to a quality of service to said message, which quality of service information is to be transmitted to said second device

said first device comprising a transmitting component for transmitting a protocol message assembled by said assembling component to said second device;

said second device comprising a receiving unit for receiving a protocol message transmitted by said first device; and

said second device comprising a detaching component for detaching quality of service related information from a received protocol message.

15. A method of transmitting information relating to a quality of service, which information is to be transmitted in at least one direction between a first device and a second device, said method comprising at least at one of said devices:
