Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to locate user equipment, then comprehensive network information can be collected, but communication overheads and bandwidth occupation increase significantly
Solution Approach 1:
The patent extracts only the essential information needed for location determination from the mirrored packets, specifically the receive port identifier and transmitter identifier. Instead of analyzing complete data packets or extensive interface data, the system selectively extracts minimal necessary information fields, thereby reducing communication overhead while maintaining location accuracy.
Solution Approach 2:
The patent applies local quality by focusing analysis on specific critical fields within the mirrored packets rather than processing entire packets. The receive port identifier and transmitter identifier are identified as the key local elements that contain location information, allowing the system to ignore irrelevant data and reduce bandwidth occupation.
2Measurement precision
If traditional location methods are used, then location information can be obtained, but real-time performance is insufficient
Solution Approach 1:
The patent implements preliminary action by having network devices continuously generate and send mirrored packets containing location information before fault occurrence. The access location information is pre-obtained and stored in the apparatus, enabling immediate fault location without waiting for additional data collection when an exception occurs.
Solution Approach 2:
The system maintains continuous operation by continuously receiving mirrored packets from network devices and continuously updating access location information. This continuous data flow ensures that the latest location information is always available, providing real-time performance for fault locating without interruption.
3Loss of information
If extensive interface data is transmitted to obtain access location, then comprehensive information is available, but bandwidth occupation increases
Solution Approach 1:
The patent extracts only the essential information needed for location determination from the mirrored packets, specifically the receive port identifier and transmitter identifier. Instead of analyzing complete data packets or extensive interface data, the system selectively extracts minimal necessary information fields, thereby reducing communication overhead while maintaining location accuracy.
4Reliability
If traditional fault locating methods are used, then fault can be located, but the process is inefficient and inaccurate
Solution Approach 1:
The patent implements preliminary action by having network devices continuously generate and send mirrored packets containing location information before fault occurrence. The access location information is pre-obtained and stored in the apparatus, enabling immediate fault location without waiting for additional data collection when an exception occurs.
Solution Approach 2:
The system establishes feedback by continuously monitoring mirrored packets and updating access location information in real-time. This feedback mechanism ensures that the apparatus always has current location data, improving both the accuracy and efficiency of fault locating by providing up-to-date information for transmission path determination.
Data Source
AI summary
This application provides a device access location obtaining method and apparatus. The method includes: receiving a mirrored packet sent by a network device, determining, based on the mirrored packet, whether a transmitter of a data packet is user equipment, and obtaining access location information of the user equipment in a network when it is determined that the transmitter of the data packet is user equipment. The mirrored packet is generated based on the data packet received by the network device, the data packet carries an identifier of the transmitter of the data packet, the mirrored packet carries the data packet or partial content of the data packet, an identifier of the network device, and a receive port identifier, and the access location information includes the identifier of the transmitter, the identifier of the network device, and the receive port identifier.
