QoS Control for Unstructured Data Packets via Indication Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation networks face challenges in controlling Quality of Service (QoS) for unstructured data packets, as they lack traditional IP headers, making it difficult for the network to parse and manage these packets effectively.
Innovation Solution
The method involves determining indication information related to QoS for unstructured data sessions and transmitting this information to target nodes, such as the User Plane Function (UPF) or User Equipment (UE), allowing them to assign and add QoS identifiers to packet headers, ensuring proper QoS control for both downlink and uplink data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network uses traditional IP header parsing methods for QoS control, then IP data packets can be properly managed and prioritized, but unstructured data packets without traditional IP headers cannot be parsed or controlled
Solution Approach 1:
The patent introduces an intermediary mechanism (indication information) that bridges the gap between unstructured data packets and QoS control requirements. Instead of directly parsing packet contents, the network uses indication information transmitted through control plane signaling to convey QoS parameters, enabling QoS control without direct packet parsing
Solution Approach 2:
The patent changes the parameter representation method from traditional IP header fields to indication information parameters transmitted via control signaling. This parameter transformation allows the network to control QoS for unstructured data by managing indication information parameters rather than parsing packet structures
2Reliability
If the network implements flow template matching for IP packets, then QoS can be enforced based on source and destination addresses, but unstructured packets without IP headers cannot be matched or identified
Solution Approach 1:
The patent applies preliminary action by pre-configuring indication information parameters and QoS policies before unstructured data transmission occurs. The network establishes QoS rules and indication information mappings in advance, so when unstructured packets arrive, the QoS control is already in place without requiring real-time packet analysis
3Measurement precision
If the system maintains separate handling procedures for IP and unstructured data, then IP QoS control remains precise, but unstructured data lacks any QoS management mechanism
Solution Approach 1:
The patent implements universality by creating a unified QoS control framework that handles both IP and unstructured data through the indication information mechanism. The same control plane procedures and indication information parameters can be applied to different data types, providing consistent QoS management across diverse packet structures

AI summary
A control method and device, SMF, UPF, UE, PCF, and AN are provided. It relates to the field of communications, and solves the problem that the network cannot perform QoS control on unstructured data packets in related art. The control method includes: when establishing a session for transferring unstructured data for a user equipment, determining indication information related to a QoS of the session; transmitting the indication information to a target node, determining, by the target node, a QoS corresponding to the session according to the indication information. The target node can determine the QoS of the session for transferring unstructured data according to the indication information sent by the SMF, thereby realizing the QoS control of unstructured data packets by the network, and ensuring the QoS of the unstructured data transmission and improving network performance.
