Router Advertisement Acknowledgement Location Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP communication networks lack an efficient method for user communication devices to accurately and reliably provide their geographic location to packet network nodes, which is essential for effective communication and service management, especially in mobile scenarios.
Innovation Solution
Wireless communication devices receive router advertisement messages and generate acknowledgement messages with header extensions containing location information, which are then transmitted to packet network nodes, allowing for the determination and communication of geographic location, enabling seamless communication and service management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user communication devices transfer acknowledgement messages to packet network nodes, then communication reliability is improved, but location information cannot be provided to the network node
Solution Approach 1:
The patent combines location information with the acknowledgement message by embedding it in a header extension field. This merging allows the device to simultaneously acknowledge receipt of the router advertisement message and provide its geographic location to the packet network node through a single integrated message structure.
Solution Approach 2:
The acknowledgement message is enhanced to serve multiple functions: it not only confirms receipt of the router advertisement message but also conveys location information to the network node. This multi-functionality resolves the contradiction by making the existing acknowledgement mechanism capable of carrying additional information without requiring separate communication channels.
2Measurement precision
If location information is embedded in acknowledgement messages, then location determination accuracy is improved, but message structure complexity increases
Solution Approach 1:
The patent segments the message structure by adding a distinct header extension field specifically for location information. This segmentation allows the location data to be clearly separated and identified within the message structure, reducing processing complexity despite the added information. The standardized extension format enables systematic handling of the enhanced message structure.
3Productivity
If header extension with location information is added to acknowledgement messages, then service management efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining standardized header extension structures and formats for location information. This standardization enables packet network nodes to efficiently process location data without complex custom parsing logic, thereby improving service management efficiency while minimizing processing complexity through predictable, pre-established message formats.

AI summary
A wireless communication device receives a router advertisement message transferred by a packet network node. The wireless communication device determines location information that corresponds to its geographic location. In response to the router advertisement message, the wireless communication device generates an acknowledgement message having a header extension that includes the location information. The wireless communication device wirelessly transmits the acknowledgement message for delivery to the packet network node.
