Reflective Mapping Initiation with Embedded Data Packet Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a specific implementation method for initiating reflective mapping in communication terminals, particularly in scenarios with small signaling overhead.
Innovation Solution
A method is introduced to initiate reflective mapping by adding a startup identifier to a data packet transmitted between communication devices, allowing the receiving device to start the reflective mapping mechanism without additional control signaling, thereby reducing overhead and ensuring efficient underlying bearer switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a startup identifier is added to data packets to initiate reflective mapping, then the ability to start reflective mapping is improved, but the signaling overhead increases
Solution Approach 1:
The patent merges the startup identifier with existing data packets by embedding it in the SDAP header or using the existing packet structure as the carrier. This combines the control function (initiating reflective mapping) with the data transmission function, eliminating the need for separate control signaling and thus reducing signaling overhead while maintaining the ability to start reflective mapping.
2Quantity of substance
If reflective mapping is initiated without additional control signaling, then signaling overhead is reduced, but the precision of initiating reflective mapping deteriorates
Solution Approach 1:
The patent uses the SDAP header or existing data packet fields as an intermediary to carry the startup identifier. This intermediary structure enables precise control signaling (by embedding specific indicator bits or fields) without requiring separate control messages, thus maintaining precision while reducing overall signaling overhead.
Solution Approach 2:
The patent changes the state of existing packet parameters (such as setting specific bits in the SDAP header or modifying existing field values) to indicate the startup of reflective mapping. By reusing existing parameters and changing their interpretation or state, the patent achieves precise control without adding new signaling elements.
3Productivity
If data packets are switched to different underlying bearers, then communication efficiency is improved, but logical processing confusion increases
Solution Approach 1:
The patent performs preliminary actions by establishing clear mapping relationships between QoS flows and data radio bearers before data transmission occurs. The startup identifier and associated configuration information prepare the receiving device in advance, so when data packets need to be switched between bearers, the device already has the necessary context and rules, reducing logical processing confusion while maintaining efficient bearer switching.

AI summary
The present disclosure provides a method for starting reflective mapping, a communication device and a storage medium. The method for starting reflective mapping applied to a first communication device, includes: when determining that first data packet is to be transmitted by first underlying bearer, adding a startup identifier of a first value to a second data packet, where the startup identifier of the first value is used to instruct a second communication device to start reflective mapping, the first data packet is a data packet transmitted by the second communication device to the first communication device, and the second data packet is a data packet that is originally to be transmitted by the first communication device; and transmitting the second data packet carrying the startup identifier of the first value by the first underlying bearer.
