FLEXIBLE SCOPE OF PACKET FILTERS FOR REFLECTIVE QUALITY OF SERVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18467028 titled 'FLEXIBLE SCOPE OF PACKET FILTERS FOR REFLECTIVE QUALITY OF SERVICE

Simplified Explanation

The patent application describes a system and method for controlling the derivation of Quality of Service (QoS) rules in a User Equipment (UE) by defining the scope of packet header fields. Here are the key points:

  • The system allows for flexible definition of the scope of packet header fields for deriving QoS rules in the UE.
  • The network provides the scope of packet header fields to the UE during PDU Session establishment or modification.
  • For IP type PDU Sessions, the network indicates whether the scope of QoS rules includes both the Source/Destination IP address pair and the Source/Destination Port numbers, or only the former.
  • For Ethernet type PDU Sessions, the network indicates whether the scope of QoS rules includes both the Source/Destination MAC address pair and the IEEE 802.1Q tag, or only the former.
  • The UE can indicate to the network whether it supports the flexible scope of packet filters for QoS rules for a PDU session.

Potential applications of this technology:

  • Mobile network operators can use this system to provide more granular control over QoS rules for different types of PDU Sessions.
  • Enterprises can benefit from improved QoS management for their network traffic, ensuring better performance for critical applications.
  • Service providers can offer differentiated QoS levels to their customers based on the specific packet header fields.

Problems solved by this technology:

  • Traditional QoS rules may not provide enough flexibility to meet the specific requirements of different types of PDU Sessions.
  • Lack of granular control over QoS rules can lead to inefficient resource allocation and suboptimal network performance.
  • The system addresses these issues by allowing the network and UE to define the scope of packet header fields for deriving QoS rules.

Benefits of this technology:

  • Improved QoS management and resource allocation in mobile networks.
  • Enhanced performance for critical applications and better user experience.
  • Increased flexibility for network operators and service providers to offer customized QoS levels.


Original Abstract Submitted

Systems and methods provide for controlling the derivation of QoS rules in the UE by flexibly defining the scope of packet header fields over which packet filter derivation is performed. The scope of packet header fields for derivation of QoS rules may be provided by the network to the UE upon PDU Session establishment or modification. For PDU Session of IP type, the network indicates to the UE whether the scope of RQoS includes both the Source/Destination IP address pair and the Source/Destination Port numbers, or only the former. For PDU Session of Ethernet type, the network indicates to the UE whether the scope of RQoS includes both the Source/Destination MAC address pair and the IEEE 802.1Q tag, or only the former. The UE may indicate to the network whether it supports the flexible scope of packet filters for RQoS for a PDU session.
