Solution Overview

Problem

Existing off-the-shelf real time simulators for network traffic are inadequate for simulating packet transmissions exceeding 64 KB, which are common in 5G wireless networks, as they fail to handle large packets efficiently.

Innovation Solution

Implementing a fragmentation and reassembly process that splits large packets into sub-packets with QoS information and timers, ensuring they are received in order and within a specified time frame, tailored for 5G network traffic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing off-the-shelf real time simulators are used for network traffic simulation, then simulation of standard packet sizes (up to 64 KB) is supported, but simulation of large packet sizes (exceeding 64 KB) common in 5G networks is inadequate

Engineering Contradiction:

Improvepacket size handling capabilityVSAvoidsimulation accuracy for large packets

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent divides large packets exceeding 64 KB into multiple smaller sub-packets, each within the 64 KB limit. This segmentation allows the simulation system to handle large packets by processing them as sequences of manageable sub-packets, thereby extending the simulator's capability to 5G network packet sizes while maintaining simulation reliability through proper reassembly of sub-packets into original packets

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If large packets are split into sub-packets, then packet delivery ordering and timing control are improved, but system complexity increases due to fragmentation and reassembly processes

Engineering Contradiction:

Improvepacket delivery ordering precisionVSAvoidfragmentation and reassembly system complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent embeds sequence numbers and timing information in the fragmentation headers during the segmentation process. This preliminary action ensures that sub-packets contain all necessary information for correct reassembly and ordering, reducing the complexity of the reassembly process while maintaining precise delivery control

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements acknowledgment mechanisms where the receiving end confirms successful receipt of sub-packets. This feedback loop ensures reliable reassembly by allowing the transmitting end to retransmit lost or delayed sub-packets, thereby maintaining delivery precision without requiring overly complex error handling protocols

Inventive Principle:

Principle #23Feedback

3Productivity

If fragmentation headers with QoS information and timers are added to sub-packets, then service prioritization and timing control are enhanced, but overhead and processing complexity increase

Engineering Contradiction:

Improvetraffic handling efficiencyVSAvoidpacket overhead

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent designs the fragmentation header to serve multiple functions simultaneously: it contains sequence numbers for reassembly ordering, QoS information for service prioritization, and timing information for delay control. This multi-functionality reduces the need for separate header fields, thereby limiting overhead growth while enhancing traffic handling efficiency through integrated control mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

In some implementations, a first device associated with a wireless simulation environment may detect that a packet is associated with a packet size that exceeds a threshold. The first device may perform a fragmentation of the packet by splitting the packet into a plurality of sub-packets. The first device may insert a header for each sub-packet that indicates quality of service (QOS) information associated with the packet and an allowed time for reassembling the packet. The first device may transmit each sub-packet of the plurality of sub-packets. A second device associated with the wireless simulation environment may receive each sub-packet of the plurality of sub-packets. The second device may perform a reassembly of the plurality of sub-packets to obtain the packet.
