Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in efficiently managing data units (DUs) in wireless devices, particularly in determining packet associations based on timestamp fields, which affects the establishment of PDU sessions and overall network performance.
Innovation Solution
A wireless device receives configuration information from an SMF to determine packet associations within data units using timestamp fields, enabling accurate packet handling and PDU session establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If timestamp fields are used to determine packet associations in data units, then packet association accuracy is improved, but device complexity increases
Solution Approach 1:
The network side pre-configures timestamp field definitions and packet association rules before data transmission. This preliminary configuration enables the wireless device to accurately associate packets using predefined timestamp criteria without performing complex real-time analysis, thereby improving measurement precision while controlling device complexity
Solution Approach 2:
Timestamp fields serve as an intermediary mechanism between packets and their associations. Instead of direct complex packet analysis, the timestamp fields act as mediators that carry timing information, enabling accurate packet association through simpler timestamp comparison operations rather than complex packet content analysis
2Productivity
If accurate packet handling is implemented through timestamp field analysis, then PDU session establishment efficiency is improved, but processing time increases
Solution Approach 1:
Packet association rules and timestamp field definitions are pre-configured by the network side before actual data transmission. This preliminary setup enables faster real-time processing during PDU session establishment, as the wireless device can directly apply predefined rules rather than performing complex real-time analysis, thus improving productivity while minimizing processing time
Solution Approach 2:
The system changes from analyzing complex packet content to using simplified timestamp field parameters for packet association. This parameter transformation reduces processing complexity and time requirements while maintaining accurate packet handling, enabling efficient PDU session establishment without significant processing time overhead

AI summary
A wireless device receives, from an SMF, a message for a PDU session establishment, wherein the message comprises a configuration information for determining whether one or more packets are associated with a plurality of packets of a data unit (DU) based on a timestamp field of the one or more packets. The wireless device determines, based on the configuration information, that a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU, and a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU. The wireless device sends, to a base station, the first packet and the second packet.
