Providing a quality of service to wireless devices attached to relay access nodes

A system for providing a quality of service (QoS) to wireless devices attached to a relay access node, the system comprising:

• a donor access node configured to provide wireless services to a first plurality of wireless devices directly attached to the donor access node without an intervening relay access node and to a second plurality of wireless devices attached to a relay access node, wherein the relay access node is communicably coupled to the donor access node via a wireless backhaul link;
• and
• a processor coupled to the donor access node, the processor for configuring the donor access node to perform operations comprising:
• comparing a first resource requirement of the first plurality of wireless devices with a second resource requirement of the second plurality of wireless devices, wherein both first and second resource requirements as associated with a same type of traffic;
• determining that the first resource requirement of the first plurality of wireless devices is smaller than the second resource requirement of the second plurality of wireless devices;
• and
• changing a class identifier of the wireless backhaul link from a default class identifier to a new class identifier to meet the second resource requirement;
• determining that the second resource requirement is smaller than the first resource requirement;
• and
• changing the class identifier from the new class identifier to the default class identifier.

A processing node for providing a quality of service (QoS) to one or more wireless devices, the processing node being configured to perform operations comprising:

• obtaining a first number of transport bearers associated with a first traffic type between a first one or more wireless devices and a wireless network, wherein the first one or more wireless devices are directly attached to a donor access node without an intervening relay access node;
• obtaining a second number of transport bearers associated with the first traffic type between a second one or more wireless devices and the wireless network, wherein the second one or more wireless devices are attached to a relay access node communicably coupled to the donor access node via a first radio bearer;
• comparing the first number with the second number;
• and
• upon determining that the second number exceeds the first number, modifying a first set of QoS parameters of the first radio bearer to a second set of QoS parameters to meet a resource requirement of the second number of wireless devices;
• determining that the second number is smaller than the first number;
• and
• returning the second set of QoS parameters to the first set of QoS parameters.
