Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to obtain access location of user equipment, then comprehensive location information can be obtained, but communication overheads increase and real-time performance deteriorates
Solution Approach 1:
The patent extracts only the essential elements needed for access location identification from complete interface data. Specifically, it extracts the receive port identifier and transmitter identifier from mirrored packets, discarding redundant data while maintaining sufficient information for accurate location determination. This extraction principle directly reduces communication overheads while preserving measurement precision.
Solution Approach 2:
The patent applies partial action by transmitting only a portion of the complete interface data - specifically, mirrored packets containing selected identifiers rather than full data sets. This partial transmission approach reduces bandwidth occupation and communication overheads while providing sufficient information for access location determination, avoiding the need to transmit excessive data.
2Measurement precision
If traditional methods are used to obtain access location of user equipment, then location information can be obtained, but real-time performance is poor
Solution Approach 1:
The patent implements preliminary action by pre-configuring network devices to generate and transmit mirrored packets containing access location information. Network devices are prepared in advance to monitor and capture relevant identifiers (receive port identifier and transmitter identifier) from data packets, so that when access location queries occur, the information is already available for immediate retrieval, improving real-time performance while maintaining accuracy.
3Speed
If mirrored packets are transmitted for access location determination, then real-time performance improves, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the mirrored packet mechanism to serve multiple functions simultaneously. The same mirrored packet infrastructure is used for access location determination, fault locating, and traffic monitoring. Network devices perform multiple tasks (generating mirrored packets, transmitting them, and processing location information) through a unified mechanism, reducing overall system complexity despite the added real-time capabilities.

AI summary
This application provides a device access location obtaining method and apparatus, and relates to the communication field. 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. In this application, the user equipment in the network is accurately located based on the mirrored packet, to obtain an access location of the user equipment.
